The current position of the actuator is detected by a servo potentiometer and fed back as actual value x. The setpoint and actual value are output simultaneously on the display. The setpoint w is formed by a current fed to the positioner which at the same time serves to supply the positioner in two-wire operation. In 3/4-wire operation the supply comes from a 24 V voltage input. The positioner operates as a predictive five-point switch by the output variable ±∆y of which the integrated actuating valves are controlled with pulse length modulation. These actuating signals cause fluctuations in pressure in the actuator chamber(s) and thus adjustment of the actuator until the control error is zero. Operation (manual) and configuration (structuring, initialization and parameterization) is effected by three keys and a display with the housing cover removed. The standard controller has one digital input (DI1). This can be configured individually and can be used for blocking the operating modes for example. With the Iy-option module, the current actuator position can be output as a two wire signal Iy = 4 to 20 mA. In addition the actuator can be monitored for two programmable limit values which respond on exceeding or dropping below the stroke or angle of rotation. The limit value alarms are output by the alarm option module which can monitor and report the function of the positioner and the actuator additionally through a fault message output. The value of the control difference dependent on the travel time is monitored in automatic mode. The fault signal is always set when the control error cannot be leveled after a certain time because for example the valve is blocked or the mains pressure is insufficient. The three digital outputs are implemented as semiconductor outputs and are error self-reporting, i.e. the outputs re- SIPART PS2 Manual A5E00074631--06 15 Design and Functional Principle spond even when the power supply fails or the electronics are defective. The actuator can also be blocked or driven to its final positions depending on the configuration for example by an external event via a digital input (DI2) on the alarm module. If you require electrically independent limit value messages from the standard controller, you will have to use the SIA module with the slot initiators instead of the alarm module. Communication with the controller is possible via the optional HART interface. To be able to use the positioner with a variety of different part-turn and linear actuators, it has a friction clutch and switchable gearing. The switchable gearing allows you to adjust the positioner for small and large lifts. You can switch using the yellow switch (8, Fig. 2-11, page 28) between 33_ (as delivered) and 90_. The friction clutch (8, Fig. 2-11, page 28) allows you to set the working range, particularly for linear actuators, after installation. You thus do not have to ensure symmetrical mounting during the installation. As it is not allowed to open the housing of an explosion-proof version in a potentially explosive atmosphere, the shaft has an externally fitted, additional friction clutch (8, Fig. 2-12, page 31). NOTICE for the explosion-proof version: Only adjust the outer friction clutch (8, Fig. 2-12, page 31). The internal friction clutch (8, Fig. 2-11 page 28) is fixed and, for the explosionproof version, must not be adjusted. 16 SIPART PS2 Manual A5E00074631--06 Design and Functional Principle 2.2 Name plate design (2) (1) (8) (7) (3) (4) (5) (1) (2) (3) (4) (6) Order number Manufacturer Product name Technical data Figure 2-1 2.3 (5) (6) (7) (8) Serial number Place of manufacture Protection class Observe manual Design name plate, example with protection class EEx ia/ib Instrument Components 14 3 15 33 O 90° 2 DI1 O 1 90 13 3/4 W 0/4...20 mA 4...20 mA 2W 4 33° 12 6.1 11 1 2 3 4 5 6 6.1 6.2 *) 10 Input: Supply air Output: Actuating pressure Y1 Display Output: Actuating pressure Y2 *) Operating keys Restrictor Restrictor Y1 Restrictor Y2 *) 9 8 7 8 9 10 12 13 14 15 7 6.2 6 5 Silencer Transmission ratio selector Adjusting wheel for frichtion clutch Terminals options modules Dummy plug Screw-type cable gland Terminal plate on cover Purging air switch in double-acting actuators Figure 2-2 View of the positioner in normal version (cover open) SIPART PS2 Manual A5E00074631--06 17 Design and Functional Principle 3 9 6.1 1 12 7 10 -- 10 1 2 3 4 5 6.1 6.2 *) 238 9 138 1 2 + 6.2 4 5 Input: Supply air Output: Actuating pressure Y1 Display Output: Actuating pressure Y2 *) Operating keys Restrictor Y1 Restrictor Y2 *) 7 8 9 10 12 8 Transmission ratio selector (only possible with positioner open) Adjusting wheel for friction clutch Terminals standard controller Terminals options modules Safety catch in double-acting actuators Figure 2-3 View of the explosion proof version of the positioner 2.3.1 Motherboard The motherboard contains all the electronic elements such as the CPU, memory, A/D converter. It also contains the display and the operating keys. In addition, the terminal strips for connecting the options modules are also on the motherboard. 2.3.2 Electrical Connections The terminals of the standard controller, the Iy- and alarm-option module are arranged at the left-hand front edges and offset against each other in staircase form.

In the IN position the inside of the housing is purged with very small amounts of clean, dry instrument air. In the OUT position the purge air is fed directly to the outside air. Figure 2-7 Purge air switch on the valve block, view of the positioner onto pneumatic connection side with cover open 2.3.6 Restrictors In order to achieve travel times of > 1.5 s in small actuators, the air rate can be reduced with the restrictors Y1 and Y2 (figure 2-8, in explosion proof version, see figure 2-5, page 19). By turning to the right the air rate is reduced up to shutting off. To set the restrictors it is advisable to close them and then open them slowly (see initialization RUN3). In the case of double-acting valves make sure that both chokes are set approximately equal. Hexagon socket 2.5 mm Y1 Y2 Figure 2-8 22 Restrictors SIPART PS2 Manual A5E00074631--06 Design and Functional Principle 2.4 Method of Operation The electropneumatic positioner SIPART PS2 forms a control circuit with the pneumatic actuator in which the actual value x is the position of the actuator bar in linear actuators or the position of the actuator shaft in part-turn actuators and the command variable w is the actuating current of a controller or a manual control station of 4 to 20 mA. The stroke or part-turn movement of the actuator is transferred by the appropriate mounting accessories, the feedback shaft and a play-free switchable gearwheel to a high quality conductive plastic potentiometer and to the analog input of the microcontroller. The current position can also be preset for the positioner via an external sensor. The detection of the stroke or rotation andle is performed by a non-contacting position sensor (Non Contacting Position Sensor) directly at the actuator. This may correct the angle error of the stroke tap, compares the potemtiometer voltage as actual value x with the setpoint w fed in at the terminals 3 and 7 and calculates the manipulated variable increments Δy. Depending on the size and direction of the control error (x-w) the piezo-controlled supply air or exhaust air valve is opened. The volume of the actuator integrates the positioning increments to actuating pressure y open which moves the actuator bar or actuator shaft approximately proportionally. These positioning increments change the actuating pressure until the control error becomes zero. The pneumatic actuators are available in single and double-acting versions. Only one pressure chamber is aerated or deaerated in the single-acting version. The resulting pressure operates against a spring. In the double-acting version, two pressure chambers are counteractive. In this case the one volume is deaerated when the other volume is aerated. See the block diagram figure 2-10, page 25. The control algorithm is an adaptive predictive five-point switch (see figure 2-9, page 24). The valves are controlled with continuous contact at large control errors (fast step zone). At medium control errors the valve is controlled by pulse length modulated pulses (short step zone). No actuating pulses are output in the small control error zone (adaptive dead zone). The dead zone adaptation and the continuous adaptation of the minimum pulse lengths in automatic operation cause the best possible control accuracy to be achieved at the lowest switching frequency. The start parameters are determined during the initialization phase and stored in a non-volatile memory. These are basically the real travel with the mechanical limit stops, the travel times, the size of the dead zone etc. In addition the number of fault messages, changes in direction and the number of strokes are determined and stored every 15 minutes during operation. These parameters can be read out and documented by the communication programs such as PDM and AMS. Conclusions as to the wear on the fitting can be drawn (diagnostic function) especially by comparing the old value with the currently determined values.

SIPART PS2 Manual A5E00074631--06 25 Design and Functional Principle 2.5 HART-function The positioner is also available with built-in HART-functions. The HART protocol allows you to communicate with your instrument with a handheld communicatorR, PC or programming unit. This enables you to configure your instrument comfortably, save configurations, call diagnostic data, display online measured values and much more. Communication takes place as frequency modulation over the existing signal lines for the command variable from 4 to 20 mA. Function The SPART PS2 is integrated in the following parameterization tools: S Handheld communicatorR S PDM (Process Device Manager) S AMS (Asset Management System) S Cornerstone (without diagnostic values/-functions) . NOTE Operation on the positioner has priority over the settings via the HART interface. Communication is aborted by a power failure at the positioner. 2.6 State as supplied There are no mechanical mounting accessories on the controller in the state as supplied. These must be ordered and installed according to the “operating instructions” depending on the application. The respective connections for single or double-acting versions are prepared at the factory as ordered. The pneumatic connections on the rear are sealed. 26 SIPART PS2 Manual A5E00074631--06 Design and Functional Principle 2.7 Installation of options modules 2.7.1 Installation of options modules in normal and intrinsically safe versions The following option modules are available for the positioner in the standard and the intrinsically safe version: -- ly-module -- Alarm module -- SIA-module -- Mechanical limit switch module -- EMC filter module The installation of the options modules is described below: Installation . The option modules are secured by a assembly covering ((1), see figure 2-11, page 28) and mechanically fixed. NOTE To install the option modules the housing of the positioner needs to be opened. As soon as the positioner is opened, the IP66 degree of protection is not guaranteed. Open positioner To open the positioner, the four screws of the housing cover must be loosened with a Phillips screwdriver. Disconnect or isolate the power supply cables. Remove the module cover (1). To do this, the two screws (1.1) must be removed with a screwdriver. .

The options modules are protected and mechanically fixed by a module cover ((1), see figure 2-12, page 31). NOTE The housing must be opened to install the options modules. The degree of protection IP66/NEMA4x is not guaranteed as long as the positioner is open. ! WARNING In areas in which the atmosphere may be potentially explosive, the explosion-proof positioner may only be supplied with electrical auxiliary power when the housing is closed and when built-in, approved electronics are used. The feed-though openings for the electronic connections must be sealed with EEX-d certified cable glands or EEx-d certified plugs or an ignition lock must be mounted at a maximum distance of 46 cm (18 inches) when using the “conduit”-system. Open the positioner See figure 2-12, page 31. Disconnect or isolate the power supply cables first. To open the positioner, the safety catch (12) must be opened and the screw-on cover unscrewed. After loosening the four fixing screws (13.1) the complete rack (13) can be removed. The actuator may have to be turned so that the clutch can be easily disengaged. Remove the module cover (1). To do this, the two screws (1.1) must be removed with a screwdriver. SIPART PS2 Manual A5E00074631--06 29 Design and Functional Principle .

The dynamic control of the Iy module makes it also error self-reporting. 31 Design and Functional Principle Installation Insert the Iy module (3) in the lower slot of the rack up to the stop and use the 6-pin flat ribbon cable (6) provided to connect it to the motherboard (see figure 2-11, page 28). 2.7.4 Alarm module The alarm module contains S 3 digital outputs and S 1 digital input Function The digital outputs serve to output fault messages and alarms. The configuration is described in chapter 4.4, page 95, with the parameters 44 to 54. By an external signal applied at digital input (DI2) the actuator can be blocked or driven to its limit positions for example depending on the configuration. The configuration is described in chapter 4.4, page 95, with the parameters 43. The alarm module is available in two versions: S explosion protected for connecting to switching amplifier EN 60947-5-6 S non-explosion protected for connection to voltage sources with a maximum 35 V The semiconductor outputs of the alarm module report an alarm (signal state Low) by switching off with high resistance. They are conductive in the High state (without alarm). The dynamic control makes them error self-reporting. The outputs are potentially isolated from the basic circuit and each other. The digital input is double. S one potential isolated for voltage level S one not potential isolated for floating contacts These two inputs are designed as logic OR links. Installation 32 Insert the alarm unit (4) below the motherboard in the rack up to the stop and use the 8-pin flat ribbon cable (5) to connect it to the motherboard (see figure 2-11, page 28). SIPART PS2 Manual A5E00074631--06 Design and Functional Principle 2.7.5 SIA module The SIA module contains: S one binary output S two binary outputs Function A collected fault message (see alarme module) is output via the binary output. The floating digital output is implemented as a self error reporting semiconductor output. The two binary outputs are used to report two mechanically adjustable limit values (L1, L2) via slot initiators. These two outputs are electrically independent of the rest of the electronics. Installation (Slot Initiator Alarm module) Proceed as follows for installation (figure 2-11, page 28):: 1. Remove all the electrical connections from the motherboard (2). 2. Loosen the two fixing screws (2.1) of the motherboard. 3. Snap out the motherboard by carefully bending the four holders. 4. Insert the SIA module (7) from above until it reaches the upper circuit board rail of the rack. 5. Push the SIA module into the circuit board rail of the rack approx. 3 mm towards the right. 6. Screw the special screw (7.1) through the SIA module into the axle of the positioner (Torque: 2 Nm): CAUTION The pin pressed into the actuating disc bearing (12) must be adjusted to just before touching with the special screw. The actuating disc bearing and the special screw must then be turned simultaneously so that the pins slot into the special screw. SIPART PS2 Manual A5E00074631--06 7. Place the insulating cover (10) over the SIA module underneath the surface of the motherboard at the container wall on one side. The recesses in the insulating cover must slot into the corresponding lugs on the container wall. Place the insulating cover on the SIA module by carefully bending the container walls. 8. Snap the motherboard into the four holders and screw it tight again with the two fixing screws (2.1). 33 Design and Functional Principle 9. Make all the electrical connections between the motherboard and the options with the ribbon cables provided and between the motherboard and potentiometers with the potentiometer cable. 10. Fix the enclosed module cover instead of the standard version with the two screws (1.1). 11. Select the plates which already exist on the standard version of the module cover from the set of plates enclosed. Stick the selected plates according to the standard version to the mounted module cover. In the case of the version which doesn’t feature explosion protection, stick the warning sign onto the side of the ground plate opposite the name plate. 12. Make the electrical connections. Setting the two limit values: . NOTE Connect a suitable display instrument such as the Initiator-Tester type 2/Ex made by Peperl+Fuchs to the terminals 41 and 42 or terminals 51 and 52 of the SIA module to be able to see the switching state of the slot initiators. . 1. Drive the actuator to the first desired mechanical position. 2. Adjust the top actuating disc (7.2) by hand until the output signal on terminals 41 and 42 changes. 3. Drive the actuator to the second desired mechanical position. 4. Adjust the bottom actuating disc (7.3) by hand until the output signal on terminals 51 and 52 changes. NOTE If you turn the actuating disc beyond the switching point up to the next switching point, you can set a high-low or a low-high change. To avoid the actuating discs being accidentally adjusted during operating, they are relatively sluggish. The following remedy might be of help if you are having trouble with the adjustment: open and close the actuator several times while holding the actuating discs. This temporarily reduces the friction. This allows an easier and finer adjustment. 34 SIPART PS2 Manual A5E00074631--06 Design and Functional Principle 2.7.6 Mechanical limit switch module The mechanical limit switch module contains the following: S A binary output for the output of a group error message) S Two switches for signaling two limit values that can be set mechanically. These two switches are electrically independent from the rest of the electronic system. Installation The installation has to be carried as follows (figure 2-11, page 28): ! WARNING ! DANGER When the mechanical limit switch module is run with AC > 16 V or DC > 35 V (low voltage), the housing must be protected against mechanical actions of > 1 Joule, since otherwise the proper functioning of the IP66 protective system is not guaranteed. When the module is supplied with low voltage, you must observe the basic safety rules before beginning work on the device, such as: 1. Deenergizing the module by disconnecting it via the disconnecting device located directly upstream from the module 2. Securing it against being turned on again 3. Ensuring that the module is disconnected from the voltage supply CAUTION The following maximal values only refer to the clamps 41 and 42 as well as the clamps 51 and 52. Maximal voltage (not Ex) AC 250 V or DC 24 V Maximal current (not Ex) AC/DC 4 A Maximal voltage (Ex) DC 30 V Maximal current (Ex) DC 100 mA When you supply one circuit breaker with extra-low voltage (AC <16 V or DC 35 < V) and the other with low voltage, you ensure that the cable insulation is doubled. When operating the switch with low voltage, you must position the low voltage circuits so that they are separated from the extra-low voltage circuits.

The positioner must be assembled – especially in a moist environment – in such a way as to rule out freezing of the positioner axle at low ambient temperature. The operating keys must be covered to prevent liquid getting in. ! WARNING In the combination of components it must be ensured that only positioners and options modules are combined which are approved for the respective area of application. This applies especially for safe operation of the positioner in areas in which the atmosphere is potentially explosive (zone 1 and 2). The instrument categories (2 and 3) of the instrument itself and those of its options must be observed. In addition, you must always make sure that no water gets into an open housing or screw-type gland. This may be the case for example when the positioner cannot be finally assembled and connected immediately. It generally applies that the positioner may only be operated with dry compressed air. Therefore use the normal water traps. An additional drying unit may even be necessary in extreme cases. This is particularly important when operating the positioner at low ambient temperatures. Please set the purge air switch (on the valve block above the pneumatic terminals) additionally to the “OUT” position. Use a sufficiently rugged console (e.g. plate thickness > 4 mm with reinforcements) for part-turn actuators and the mounting kit “linear actuator” or integrated connection for linear actuators. 3.3.1 Instructions for using positioners in a wet environment This information gives you important instructions for the assembly and operation of the positioner in a wet environment (frequent, heavy rain and/or prolonged tropical condensation) in which the IP66 degree of protection is no longer sufficient and especially when there is a danger that water may freeze. To prevent water getting into the instrument in normal operation (e.g. through the exhaust air openings) or the display being poorly legible, please avoid the unfavorable installation positions illustrated in figure 3-5. 44 SIPART PS2 Manual A5E00074631--06 Preparing for Operation Figure 3-5 Favorable and unfavorable installation positions If conditions oblige you to operate the positioner in a unfavorable installation position, you can take additional precautionary measures to prevent penetration by water. . NOTE Never clean the positioner with a high pressure water jet because the IP66 degree of protection is inadequate protection for this. The necessary additional measures to prevent penetration by water depend on the installation position chosen and you may additionally require: S screw-type gland with sealing ring (e.g. FESTO: CK –1 / 4–PK–6) S plastic hose approx. 20 to 30 cm (e.g. FESTO PUN- 8X1,25 SW) S cable straps (number and length depends on local conditions) Procedure S Connect the pipes in such a way that rain water which runs along the pipes can drip off before it reaches the terminal strip of the positioner. S Check the electrical connections for perfect firm contact. S Check the seal in the housing cover for damage and contamination. Clean and replace if necessary. S Mount the positioner if possible so that the sinter bronze silencer faces downwards on the underside of the housing (vertical installation position). If this is not possible, the silencer should be replaced by a suitable screw-type gland with a plastic hose. SIPART PS2 Manual A5E00074631--06 45 Preparing for Operation Assembly of the screw-type gland with plastic hose S Unscrew the sinter bronze silencer from the exhaust air opening on the underside of the housing. S Screw the screw-type gland mentioned above into the exhaust air opening. S Mount the above mentioned plastic hose on the screw-type gland and check the good fit. S Fix the plastic hose with a cable strap to the fitting so that the opening faces downwards. S Make sure that the hose has no kinks and the exhaust air can flow out unhindered. 3.3.2 Instructions for using positioners which are exposed to strong accelerations or vibrations NOTICE for explosion-proof versions: Only adjust the outer friction clutch (8, Fig. 2-12, page 31). The internal friction clutch (8, Fig. 2-11, page 28) is fixed and, for the explosionproof version, must not be adjusted. The electro-pneumatic positioner SIPART PS2 has a friction clutch and switchable gearing and can thus be used universally for part-turn and linear actuators. This means that, for part-turn actuators you don’t have to worry about the zero point and for linear actuators, you don’t have to worry about symmetrical mounting, as you can adjust the working range after installation, with the help of the friction clutch. The switchable gearing allows you to also adjust the positioner for small or large lifts. Occasionally it can happen, that in the rough environment of process systems (e.g. due to incorrectly fitted valves or if “steam pulses” occur) that the shaft to monitor the position of the SIPART PS2 positioner is exposed to extreme acceleration, which far exceeds its specified load limits, and which could result in an unwanted shift in the friction clutch or in the gears in the position monitoring jumping briefly out. For cases like this, as standard, the SIPART PS2 positioner is fitted with a locking device for the friction clutch and you can also lock the setting of the transmission ratio selector. This means that an unwanted change to the position monitoring due to the above mentioned effects can be reliably prevented. Both of these locking options are labeled via additional tags inside the device (see Figure 3-6, page 47). Note that these locks are only required if extreme acceleration or strong vibration might be present within your process. 46 SIPART PS2 Manual A5E00074631--06 Preparing for Operation After you have installed the positioner and put it fully into operation, you can set the torque for the friction clutch as follows: Procedure S On the module cover, insert an ordinary 4 mm wide screwdriver into a slot on the yellow wheel. S Now use the screwdriver to move the yellow wheel to the left, until you can feel that it clicks in. This increases the torque of the friction clutch. S You can recognize a locked friction clutch by an approx. 1 mm wide gap between the yellow and black wheels. S If you have to set the zero pint e.g. after exchanging the actuator, first reduce the torque by turning the yellow wheel to the right until you hit the stop. After setting the zero point, you can refix the friction clutch as described above. Starting from the neutral setting (as delivered), you can lock the transmission ratio selector as follows: S Adjust the yellow wheel underneath the terminals with an ordinary 4 mm wide screwdriver to correspond to the setting that you would like (33_ or 90_), turning to the left or right, until you can feel that it clicks in. S Please note that you can only adjust the transmission ratio selector after releasing the fixing. For this reason you first have to put the yellow ring into the neutral position, if you have to adjust the transmission ratio selector e.g. after exchanging the actuator).

This applies for instance with continuous and heavy vibration, increased or too low ambient temperatures and in the case of nuclear radiation. The separate attachment of position displacement sensor and controller unit can help here. A universal component is available which is suitable both for linear and part-turn actuators. You require the following: S The external position detection system (order no. C73451-A430-D78). This consists of a SIPART-PS2-housing with integrated friction clutch, built-in potentiometer and various dummy plugs and seals. S or a Non-Contacting Position Sensor (e.g. 6DR4004-6N). S The controller unit, any positioner version. S The EMC filter module, this is is a set together with cable clips and M-20 screw-type cable gland and has the order number C73451-A430-D23. The EMC filter module must be installed in the positioner. The installation instructions enclosed with the EMC filter module explain how to assemble the components. S A 3-wire cable for connecting the components. This EMC filter module should always be used for the controller unit when any actuator-mounted potentiometer (resistance 10 kΩ) is to be used instead of the position detection system C73451-A430-D78. ! 48 WARNING The explosion-proof version may not be run together with the external position detection system.

NOTE Any necessary options modules must be installed before electrical connection (see chapter 2.7, page 27). N.B.: The transmission ratio selector can only be set when the positioner is open. Therefore check this setting before closing the controller. ! WARNING The specifications of the examination certificate valid in your country must be observed. Electrical connection in hazardous areas The national directives and laws which apply in your country for hazardous areas, must be followed for electrical installations. In Germany these are, for example: -Working reliability regulations -Regulations for installing electrical equipment in hazardous areas, DIN EN 60079-14 (in the past VDE 0165, T1). -The EC type examination certificates SIPART PS2 Manual A5E00074631--06 57 Preparing for Operation ! WARNING If the intrinsically safe version is operated with a higher operating voltage by mistake, the positioner must no longer be used for intrinsically safe application. The explosion-proof positioner may only be supplied with electrical power in areas in which the atmosphere may be potentially explosive when the housing is closed. Where power supply is required, we recommend checking the power supply to ensure that it corresponds with that on the name plate and with the test certification valid for your country. The feed-though openings in the explosion-proof version for the electronic connections must be sealed with EEX-d certified cable glands or EEx-d certified plugs or an ignition lock must be mounted at a maximum distance of 46 cm (18 inches) when using the “conduit”system. The plastic housing is metal lined to increase the electromagnetic compatibility (EMC) against high frequency radiation. This screen is connected electrically to the threaded bushes shown in figure 3-12, page 58. Please bear in mind that this protection can only be effective if you connect at least one of these bushes with grounded fittings by electrically conductive (blank) mounting parts. Shield Figure 3-12 58 Base plate SIPART PS2 Manual A5E00074631--06 Preparing for Operation . NOTE Use standard M20 x 1.5 cable gland nuts to ensure leakage (IP-protection of the housing) and for the necessary tensile strength use only cables with a cable diameter ≥ 8 mm, or for smaller diameters use a suitable sealing insert. For the NPT version, the positioner will be delivered with an adapter. Make sure that when fitting a part into the adapter, that the maximum permissible torque of 10 Nm is not exceeded. NOTE for use in zone 2: Non-sparking equipment for Zone 2 may not be connected or disconnected under power in normal operation. However, during installation or repair work the positioner may be connected or disconnected even under power (see also certificate for zone 2). NOTE for use in two-wire systems: Never connect the current input (terminal 6 and 7) to a voltage source as this could destroy the positioner. Always use a current source with a maximum output current of 20 mA. To maintain the power supply, the input current must be ≥3.6 mA. 3.4.1 Connection in non-intrinsically safe and explosion proof version + 4 to 20 mA J 6 7 8 9 10 E A Positioner Digital input 1 6DR50x0-xNxxx 6DR5011-xNxxx 6DR51x0-xNxxx 6DR5111-xNxxx 6DR50x5-xExxx 6DR51x5-xExxx Only for: HART Communicator Figure 3-13 6DR51x0-xNxxx 6DR5111-xNxxx 6DR51x5-xExxx Two-wire connection SIPART PS2 Manual A5E00074631--06 59 Preparing for Operation + Positioner 2 3 4 5 4 to 20 mA J 6 7 8 9 10 E 6DR53x0-xNxxx 6DR52x5-xExxx 6DR53x5-xExxx A Digital input 1 HART Communicator Only for: 6DR52x5-xExxx Figure 3-14 Two-wire connection + 2 3 4 5 18 to 30 V U + *) 0/4 to 20 mA *) J 6 7 8 9 10 HART Communicator Positioner E 6DR53x0-Nxxx 6DR52x5-Exxx 6DR53x5-Exxx A Digital input 1 Only for: 6DR52x5-xExxx *) only for three-wire connection Figure 3-15 60 Three-/four-wire connection SIPART PS2 Manual A5E00074631--06 Preparing for Operation Current output + UH E 61 62 ≤35 V J + Iy module: 6DR4004-8J Figure 3-16 Iy-module 6DR4004-8J, not Ex Digital inputs and outputs Alarm module 6DR4004-8A +13 V + ≤30 V +4,5 V 11 12 21 22 Digital input 2 +3 V 1K + 35 V 31 32 Fault message 1K + 35 V 41 42 Limit value A1 1K + 35 V Figure 3-17 ≥1 51 52 Limit value A2 Alarm module 6DR4004-8A, not Ex SIPART PS2 Manual A5E00074631--06 61 Preparing for Operation SIA module Switching amplifier according to EN 60947-5-6 SIA module 6DR4004-8G 1K21 + <35 V 31 32 8.2 V 41 42 Limit value A1 8.2 V 51 52 Limit value A2 + 10K Fault message + Figure 3-18 SIA module 6DR4004-8G, not Ex Mechnical limit switch module Limit switch module 6DR4004-8K 1K21 + <35 V = + DC 24 V AC/DC 4 A + Figure 3-19 max.

NOTE In order for spring-loaded pneumatic actuators to be able to reliably exploit the maximum possible travel, the supply pressure must be sufficiently greater than the maximum required final pressure of the actuator. After installing the device, check the pneumatic connections of the entire assembly for leakage. Any leakage would cause not only continuous consumption of compressed air but also would cause the positioner to continually endeavor to compensate for the variance in position, leading in time to premature wear of the whole control mechanism. SIPART PS2 Manual A5E00074631--06 71 Preparing for Operation 3.6 Commissioning Once the positioner has been fitted to a pneumatic actuator, it must be provided with electrical and pneumatic auxiliary power. Then you can then adapt the position controller to the respective actuator by parameterizing and initializing it. Mode” operating mode (which can also if necessary be attained by “PRST”) -- “NOINI” will flash. If the positioner has not been initialized it will be in the “P Manual Mode“ operating mode (which can also if necessary be attained by “PRST”) -- “NOINI“ will flash. This initialization can be effected in three different ways: S Automatic initialization Initialization takes place automatically. Hereby the positioner determines the direction of action, the stem travel and the angle of rotation, the travel times of the actuator one after the other and adapts the control parameters to the dynamic behavior of the actuator. S Manual initialization The stem travel or angle of rotation of the actuator can be set manually, the other parameters are determined as in automatic initialization. This function is useful in actuators with soft limit stops. S Copying initialization data (positioner exchange) In the devices with HART function the initialization data of a positioner can be read out and copied to another positioner. This enables a defective device to be changed without having to interrupt an ongoing process by initialization. Only a few parameters need to be set in the positioner prior to initialization. The others are defaulted so that they do not normally need to be adjusted. You will have no problems with commissioning if you observe the following points. The possible operating modes and parameters, together with the adjustment capabilities and their effects are described in chapter 4, page 89 “Operation“. . NOTE N.B.: The operating pressure should be at least one bar greater than is necessary for closing/opening the valve during initialization. However, the operating pressure may not be higher than the maximum permissible operating pressure of the actuator. N.B.: The transmission ratio selector can only be set when the positioner is open. Therefore check this setting before closing the housing. 72 SIPART PS2 Manual A5E00074631--06 Preparing for Operation 3.6.1 Preparations for linear actuators 1. .

This allows for example a positioner to be changed on a running system in which automatic or manual initialization cannot be performed without disturbing the process. NOTICE Initialization (automatic or manual) should be performed as soon as possible afterwards because only then can the positioner be optimally adapted to the mechanical and dynamic properties of the actuator. Data are transmitted from the positioner to be replaced to the replacement instrument via the HART®- communication interface. The following steps must be performed to exchange a positioner: 1. Read in and save instrument parameters and initialization data (determined in initialization) of the instrument to be replaced with PDM (Process Device Manager). This step is unnecessary if the instrument has been parameterized with PDM and the data have already been stored. 2. Fix the actuator in its momentary position (mechanical or pneumatic). 3. Read and note the current position actual value of the positioner to be changed. If the electronics are defective, determine the current position by measuring on the actuator or valve. 4. Disassemble the positioner. Mount the lever arm of the positioner on the replacement instrument. Mount the replacement instrument on the fitting. Move the transmission ratio selector to the same position as the defective instrument. Copy the instrument data and initialization data from the PDM or handheld. 5. If the displayed actual value does not match the noted value of the defective positioner, set the correct value with the friction clutch. 6. The positioner is now ready to operate. The accuracy and dynamic behavior may be restricted in relation to correct initialization. The position of the hard stops and the related maintenance data may show deviations in particular. Therefore initialization must be performed at the earliest opportunity. SIPART PS2 Manual A5E00074631--06 87 Preparing for Operation 88 SIPART PS2 Manual A5E00074631--06 Operation 4 Operation The following chapter describes the operation of the positioner. 4.1 Display The LC display has two lines whereby the lines have different segmentation. The elements of the top line consist of 7, those of the bottom line of 14 segments. The contents of the display depend on the selected operating mode (see chapter 4.3, page 92) . NOTE If the positioner is operated in ranges with temperatures below --10 °C the liquid crystal display becomes sluggish and the display refresh rate is reduced considerably. Figure 4-1 shows you the various display options. The meaning of further display capabilities is detailed in chapter 4.3 page 139. 4.2 Input keys The positioner is operated by three keys (figure 4-2, page 91) the function of which depends on the selected operating mode. In the explosion proof version of the positioner the input keys are underneath a key cover which can be lifted up after loosening the cover screw. . NOTE The input keys of the explosion proof version must be covered to prevent liquid getting in. The IP66/NEMA4x degree of protection is not guaranteed when the housing is open or the key cover is open. The housing cover must be removed to operate the keys in the normal and intrinsically safe versions of the positioners.

Firmware version, example: 4.00.00 SIPART PS2 Manual A5E00074631--06 91 Operation 4.3 Operating modes The positioner can be operated in five operating modes. 1. P-manual mode (ex-factory state) 2. Configuration and initialization 3. Manual mode (MAN) 4. Automatic (AUT) 5. Diagnostic display Figure 4-4 gives you an overview of the possible operating modes and the change between them. Figure 4-4 92 Change between the operating modes SIPART PS2 Manual A5E00074631--06 Operation P-manual mode (ex-factory state) The display of the positioner shows you the current potentiometer setting in the top line and “NOINIT” flashes in the second line. You can move the actuator with the decrement and increment key . In order to adapt the positioner to your actuator, you have to change to the Configuration menu. See also chapter 3.6, page 72 “Commissioning”. Output of alarms and position feedback is possible after successful initialization. Configuration and initialization for To go to the Configuration menu, press the operation mode key at least 5 seconds. In the Configuration menu you can adapt the positioner individually to your actuator and start initialization. Only a few parameters need to be set in the positioner prior to initialization. The others are defaulted so that they do not normally need to be adjusted. You can block the Configuration menu against manipulation by an appropriately parameterized and activated digital input. Which parameters you need to set and all other parameters are explained in chapter 4.4, page 95 Parameters. The configuration mode can be reported by outputting a parameterizable fault message, a position feedback or output of limit values A1 and A2 is not possible. . NOTE If the electric power supply fails during configuration, the positioner switches back to the first parameter after recovering the power supply, values which have already been parameterized are retained. When doing this, please note that the new value will only be saved when leaving the configuration menu or when another parameter is selected. Without a power failure you re-enter the configuration menu at the point you exited it when you call the Configuration menu again. SIPART PS2 Manual A5E00074631--06 93 Operation at the same time at the same time at the same time at the same time to Figure 4-5 Overview: Configuration Manual mode (MAN) . In this operating mode you can move the actuator with the decrement ( ) and increment keys ( ) and the current position is held regardless of the setpoint current and any leakages. NOTE You can move the actuator quickly by pressing the other direction key additionally whilst keeping the direction key selected first pressed. The manual mode can be reported by outputting a parameterizable fault message, a position feedback or output of limit values A1 and A2 is only possible in automatic mode. . NOTE The positioner switches over to automatic mode automatically after an electrical power failure. Automatic (AUT) The automatic mode is the normal mode. In this mode the positioner compares the setpoint current with the current position and moves the actuator until the control deviation reaches the parameterizable dead zone. Error messages are output if this is not possible for various reasons. Diagnostic display In this operating mode you can have the current operating data (such as number of strokes, number of changes in direction, number of faults messages, etc.) displayed (see table 4-1, page 123). From the automatic or manual mode you go to the diagnostic display by simultaneously pressing all three keys for at least two seconds. 94 SIPART PS2 Manual A5E00074631--06 Operation See chapter 4.5, page 122 for further information. . NOTE The respective operating mode (MAN or AUT) of the positioner is retained when you switch to the diagnostic display, i.e. in automatic operation the specified setpoint is still used for controlling and in manual operation the position last reached is retained. 4.4 Parameters All the parameters of the positioner are listed in this chapter. Figure 4-6 shows an overview of the parameters. The parameter name is shown once in plain text and once as it appears in the display. The function of the parameter is described briefly in the “Function” column. In addition, the possible parameter values, the physical unit and the factory setting of the parameters are shown. SIPART PS2 Manual A5E00074631--06 95 Operation Figure 4-6 96 Parameter table of the positioner SIPART PS2 Manual A5E00074631--06 Operation The following configuration block diagram shows the effects of the parameters. Figure 4-7 Configuration block diagram SIPART PS2 Manual A5E00074631--06 97 Operation Normally adjustment of the first three following parameters is completely sufficient to enable a positioner to be operated by an actuator. If you wish to become familiar with all details of the positioner, try out incrementally the effects of the remaining parameters by selective trials. . NOTE In particular if the positioner has previously been operated using a different actuator, it must always be reinitialized in order to restore the factory settings. Only in this way can the positioner matching process start from known conditions. The parameter “55.PRST” is provided for this purpose. This is also recommended if multiple parameters have been changed in a single session, the effects cannot be assessed and unintended consequences may result. 1.YFCT Positioning actuator type This is to match the positioner with the respective actuator and where necessary to the position sensor being used. The following adjustment capabilities are provided: S YFCT = turn This adjustment is necessary for the part-turn actuator. If “turn” is selected, the following parameter “2. YAGL” is automatically set to 90_ and cannot be changed. S YFCT = WAY (Factory setting) This is necessary for a linear actuator. This allows the positioner to compensate for the non-linearity that arises due to the conversion of the linear movement of the linear actuator into the part-turn movement of the feedback shaft. For this the positioner is factory set so that it shows between “P 49.0 and P 51.0” when the arm on the feedback shaft is vertical to the linear actuator spindle. S YFCT = LWAY This must be adjusted, if an external linear potentiometer is to be connected to a linear actuator. TIP: use this adjustment also for part-turn actuators with reverse direction of control action. S YFCT = ncSt Use this when an NCS is fitted to a part-turn actuator. S YFCT = -ncSt This must be set when an NCS is used with a part-turn actuator with reverse direction of control action. S YFCT = ncSL This must be set when an NCS is used with a linear actuator. 98 SIPART PS2 Manual A5E00074631--06 Operation S YFCT = ncSLL This must be adjusted if an NCS is to be connected to a linear actuator with the position converted by an arm into a part--turn movement. . NOTE After “LWAY, ncSt, --ncSt or ncSL” have been adjusted, the parameter “3. YWAY” will not be displayed. Rated angle of rotation of the feedback shaft 2.YAGL In part-turn actuators, an angle of 90° is preset automatically by 1.YFCT = turn (see above). In linear actuators (1.YFCT = WAY) a value of 33° or 90° can be selected depending on the stroke range: S 33° for strokes ≤ 20 mm S 90° for strokes > 20 mm When using the lever up to 35 mm, both angles of rotation (33° and 90°) are possible. The long lever (> 35 mm stroke) is only designed for an angle of rotation setting of 90°. It is not part of the mounting kit set 6DR4004-8V but must be ordered separately under order number 6DR4004-8L. . NOTE The setting of the transmission ratio selector on the positioner (see figure 2-2, page 17 and figure 2-3, page 18) must correspond to the angle value selected under “2.YAGL”. Lever arm transmission 3.YWAY Selection of the lever arm range: serves to display the real stroke after initialization. The use of this parameter is optional. You only need to set this parameter if you want to have the way in mm displayed at the end of the initialization. If the parameter value “oFF” is selected here, the real stroke is not displayed after initialization. . NOTE The specification “YWAY” must match the mechanical lever arm transmission. The carrier must be set to the value of the actuator stroke, if this is not scaled to the next highest scaled value. SIPART PS2 Manual A5E00074631--06 99 Operation Automatic initialization (see chapter 3.6, page 72) 4.INITA By selecting “Strt” and pressing the increment key for at least 5 seconds, automatic initialization is started. The initialization process is displayed by “RUN 1” to “RUN 5” (see figure 3-35, page 83 to figure 3-38, page 86). Manual initialization 5.INITM By selecting “Strt” and pressing the increment key for at least 5 seconds, manual initialization is started. The manual initialization process is described in chapter 3.6.3, page 76 and chapter 3.6.6, page 81. . NOTE If the positioner has already been initialized, for INITA and INITM it is possible to transfer it to its non-initialized state without changing the remaining parameters by pressing the decrement key for 5 s. 6.SCUR Current range of the setpoint The selection of the current range depends on the connection type. “0mA” (0 to 20 mA) is only possible in three-/four-wire connections (see figure 3-23, page 64). 7.SDIR Setpoint direction (see figure 4-8, page 101) The setting of the setpoint direction serves to reverse the direction of action of the setpoint. It is used mainly for the split range mode and in single-acting actuators with the safety position “up”. 8.SPRA 9.SPRE Split range start (see figure 4-8) and Split range end (see figure 4-8) The parameters “8.SPRA” and “9.SPRE” in connection with the parameter “7.SDIR” serve to restrict the active setpoint range. In this way split range tasks can be solved with the following characteristics.

When switching over from manual operation to automatic the active setpoint is adjusted to the setpoint on the positioner with the setpoint ramp. This bumpless manual/automatic switchover avoids excessive pressure increases on long pipelines. In the position TSUP = Auto the slower of the two travel times determined during initialization is used for the setpoint ramp. TSDO is then ineffective. 12.SFCT Setpoint function (see figure 4-9, page 102) Non-linear valve characteristics can be linearized with this function and any flow characteristics simulated in linear valve characteristics. SIPART PS2 Manual A5E00074631--06 101 Operation Six valve characteristics are stored in the positioner S linear (12.SFCT = Lin, factory setting) S equal percentage 1 : 25 (12.SFCT = 1:25) S equal percentage 1 : 33 (12.SFCT = 1:33) S equal percentage 1 : 50 (12.SFCT = 1:50) S inverse equal percentage 25 : 1 (12.SFCT = n1:25) S inverse equal percentage 33 : 1 (12.SFCT = n1:33) S inverse equal percentage 50 : 1 (12.SFCT = n1:50) S freely adjustable (12.SFCT = FrEE) Setpoint turning points 13.SL0 to 33.SL20 A flow parameter can be assigned to the respective setpoint turning value at an interval of 5 %. These points lead to a polygon chain with 20 straight lines which therefore represents a projection of the valve characteristic. 100% Example: 39 YCLS = UP 41YCUP = 75.0 100% 90 80 80 70 70 Modulation range 90 60 50 9 SFCT = Lin 40 Limit for tight closing x Example: 39 YCLS = UP 41 YCUP = 85.0 Setpoint turning point Example: 18 SL5 = 45.0 60 40 Example: 39 YCLS = DO 40 YCDO = 15.0 20 0 10 20 30 40 50 60 Example: 39 YCLS = DO 40YCDO = 10.0 20 Setpoint w 0 Limit for tight closing 30 10 70 80 90 12 SFCT = FrEE 50 Limit for tight closing 30 Modulation range Limit for tight closing x 100 % 10 Setpoint w 0 0 10 20 30 40 50 60 70 80 90 100 % SL 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Figure 4-9 Setpoint characteristic, manipulated variable standardization and tight closing function The setpoint vertex values can only be input at 12.SFCT=FrEE. You may only enter a strictly monotonous characteristic, and two consecutive vertex values must differ by at least 0.2 %. 102 SIPART PS2 Manual A5E00074631--06 Operation Dead zone of the controller 34.DEBA At dEbA = AUto the dead zone in automatic operation is adapted continuously to the requirements of the control circuit. The dead zone is gradually increased on detecting a control oscillation. The reverse adaptation takes place by a time criterion. In the other discrete settings the fixed value is used for the dead zone. Manipulated variable limiting start (see figure 4-9 and 4-10) and Manipulated variable limiting end (see figure 4-9 and 4-10) 35.YA 36.YE With the parameters “YA” and “YE” the mechanical actuating distance (from stop to stop) is limited to the set values. In this way the mechanical setting range of the actuator can be limited to the active flow and the integral saturation of the commanding controller avoided. . NOTE YE must always be set to greater than YA. 37.YNRM Manipulated variable standardization (see figure 4-9 and 4-10) With limiting of the manipulated variable (by “35.YA” and “36.YE”) two different scalings are produced for the display and the position feedback via the current output (MPOS or FLOW). The MPOS scaling shows the mechanical position (0 to 100%) between the hard stops of the initialization. This is not affected by the parameters “35.YA” and “36.YE”. The parameters “35.YA” and “36.YE” are displayed in the MPOS-scale. The FLOW-scale is the standardization (0 to 100%) to the range between “35.YA” and “36.YE”. The setpoint w (0 to 100%) is always referred to this range. This gives (also by using valve characteristics) a quasi-flow-proportional display and position feedback Iy. To calculate the control difference, the setpoint is also shown in the appropriate scale on the display.

Stroke (actual value) YE = 80% Dependence on the stroke of standardization and on YA and YE in the example of an 80 mm linear actuator Manipulated variable direction of action The direction of action (rising or falling) of the display and the position feedback (Iy) can be set with this. 39.YCLS Tight closing with manipulated variable (see figure 4-9, page 102) With this function the valve can be driven to the seat with the maximum actuating force of the actuator (continuous contact of the piezo-valves). The tight closing function can be activated on one side or for both limit positions. YCLS becomes active when the setpoint is below the value set with parameter “YCDO” or above that set with parameter “YCUP”. 104 SIPART PS2 Manual A5E00074631--06 Operation . NOTE If the control function to close tightly is activated, for parameter “49. LIM” the monitoring of the control deviation in each overrun direction (YCDO: < 0 %, YCUP: > 100 %) is disabled. This function is particularly useful for valves with a soft seating. For long term monitoring of the end-stop positions, we recommend activating the parameters “52. ZERO” and “53. OPEN”. Value for tight closing, bottom and Value for tight closing, top 40.YCDO 41.YCUP . NOTE “40.YCDO” must always be set to less than “41.YCUP”. The tight closing function has a fixed hysteresis of 1 %. “40.YCDO” and “41.YCUP” relate to mechanical stops and are independent of the settings of “7.SDIR” and “38.YDIR”. 42.BIN1 43.BIN2 Function digital input 1 (see figure 4-6, page 96) and Function digital input 2 (see figure 4-6) The parameters “BIN1” and “BIN2” can be set individually depending on the purpose. The direction of action can be adapted to an NCC or an NOC. S BIN1 or BIN2 = on or --on Digital messages of the periphery (e.g. pressure or temperature switches) can be read out via the HART interface or lead to responding of the fault message output by OR linking with other messages. S BIN1 = bLoc1 The Configuration operating mode is locked to prevent it being adjusted (e.g. by a wire jumper between terminals 9 and 10). S BIN1 = bLoc2 If digital input 1 has been activated, manual operation is also locked in addition to the Configuration operating mode. S BIN1 or BIN2 = uP or doWn (contact closes) or --uP or --doWn (contact opens). The actuator drives the linear actuator to the upper or lower stop when the digital input is activated with continuous contact. S BIN1 or BIN2 (contact closes) = StoP or --StoP (contact opens). SIPART PS2 Manual A5E00074631--06 105 Operation With activated digital input the piezo-valves are blocked and the actuator remains in the last position. Leakage messages can then be executed without initialization function. S BIN1 oder BIN2 = PSt oder --PSt Depending on settings, a partial stroke test can be initiated via binary input 1 or 2 by actuating an opener or closer. S BIN1 or BIN2 = oFF (factory setting) no function special function of DI1: If the digital input 1 is activated in P manual operation by a jumper between terminals 9 and 10, , when the operating mode key is pressed the firmware version will be displayed. line of the display. If one of the above named functions is selected with the parameters “BIN1” and “BIN2” simultaneously, then “Blocking” has priority over “Up” and “Up” priority over “Down”. 44.AFCT Alarm function The actuator can report the exceeding (max.) or dropping below (min) of a specified stroke or angle of rotation. The response of the alarms (limit values) is related to the MPOS-scaling (see figure 4-10, page 104). The alarms are reported by the alarm module (order no. 6DR4004-6A or -8A). In addition the alarms can be read out through the HART interface (optional). The direction of action of the digital outputs can be adapted from high active to low active sequence systems.

NOTE If you have activated the extended diagnostics (parameter 51.XDIAG) with On2 or On3, the alarms cannot be output via the alarm unit. However, the message is possible via HART communication at any time. 45.A1 46.A2 Response threshold alarm 1 and Response threshold alarm 2 The alarm thresholds are related to the mechanical path (MPOS-scale). 47. FCT Function of the fault message output The fault message output serves as a group message for following faults: S Control error (e.g. by actuator fault, valve fault, compressed air failure) with the parameters “48. TIM” and “49. LIM” S Positioner not in automatic mode S Digital input activated (see parameter “42.BIN1” and “43.BIN2”) S Exceeding of a limit value (e.g. way integral or valve seat, see parameter 50 to 54) It also responds at: S Power failure S Processor fault The direction of action of the digital outputs can be adapted from high active to low active sequence systems. For more information on error messages, see chapter 4.5.3 OnlineDiagnostics, page 131. SIPART PS2 Manual A5E00074631--06 107 Operation Monitoring time for setting the fault messages 48. TIM The set value(s) is/are for the specification of the time, within which the positioner must have reached a compensated state. The corresponding response threshold is preset with “49. LIM”. If the set time is exceeded, the fault message output is set. . NOTE If the tight closing function is activated, for parameter “49. LIM”, the monitoring of the control deviation in each overrun direction (YCDO: < 0 %, YCUP: > 100 %) is deactivated. This function is particularly useful for valves with a soft seat. For the long-term monitoring of the endstop positions, we recommend activating the parameters “F. ZERO” and “G. OPEN”. You can find more information on fault messages in chapter 4.5.3 Online Diagnostics. Response threshold for fault messages 49. LIM A value (%) can be set here for the permissible control deviation for triggering the fault message. If parameters 48 and 49 are set to “Auto” (factory setting), the fault message is set if the short step zone is not reached within a certain time. Within 5 to 95 % of the actuator travel, this time is 10 to 90 % of 10 times the initialization actuating time. Preset 50.PRST Establishes the factory setting and resets the initialization. . NOTE After “Preset” the positioner needs to be re-initialized. All previously determined maintenance parameters are deleted. 108 SIPART PS2 Manual A5E00074631--06 Operation 51.XDIAG Activation of the extended diagnostics The extended diagnostics is deactivated at the factory, parameter 51 is therefore at “OFF”. There are three operating modes for activating the extended diagnostics: S On1: The extended diagnostics is activated and the threshold 3 error messages are also output via the fault message output. S On2: The extended diagnostics is activated, the threshold 2 error messages are output via alarm output 2 and the threshold 3 error messages are also output via fault message output. S On3: The extended diagnostics is activated, the threshold 1 error messages are output via alarm output 1, the threshold 2 error messages are output via alarm output 2 and the threshold 3 error messages are also output via the fault message output. . NOTE Please note that the menu items of the extended diagnostics from A. PST to P. PAVG are only displayed in the display after selecting one of the three On operating modes. With the factory setting, the parameters of menu items A to P are deactivated by default (OFF). The corresponding parameters are only displayed once you have activated the relevant menu item with “On”. SIPART PS2 Manual A5E00074631--06 109 Operation A. PST Partial stroke test This parameter activates the partial stroke test for the cyclic or manual partial stroke test of Up/Down and modulating valves. The partial stroke test can be triggered via keyboard, a binary input or the HART communication. A1.STPOS Start position The start position of the partial stroke test is specified here within the range of 0.0 to 100.0%. A2.STTOL Start tolerance The start tolerance in relation to the start position is specified here in the range of 0.1 to 10.0%. That means, with a start position of e.g. 50% and a start tolerance of 2%, a partial stroke test can only be triggered during operation if the current position is between 48 and 52%. A3.STEP Step height Input of the step height of the partial stroke test within the range of 0.1 to 100.0%. The factory setting is 10.0%. A4.STEPD Step direction Input of the step direction of the partial stroke test. The following options are available: “up”, “do” (down), “up do” (up and down). If “up” is selected, the actuator is moved in a controlled manner from its start position to the target position (start position + step height) and then back to the original position in a controlled way once the target position has been reached. The procedure for the “do” option is the same but in the opposite direction. With “up do”, the actuator first travels in a controlled manner from its start position to the upper target position (start position + step height), then controlled from the upper to the lower target position (start position -- step height). After reaching the lower target position, it returns to its original position in a controlled manner. A5.INTRV Test interval Input of the interval for the cyclic partial stroke test within the range of one day to 365 days. 110 SIPART PS2 Manual A5E00074631--06 Operation A6.PSTIN Partial stroke test reference step time (PSTIN = Partial Stroke Test Initialization) Measurement of the reference step time for the partial stroke test. After the initialization of the device, the calculated (C = calculated) average actuating time of the control valve is displayed in seconds in the form: C ###.#. This time can be used as reference step time, however it is only a rough guide value. That is why it is recommended to measure the reference step time here after the specification of the partial stroke test (parameters A1 to A5) by pressing the Greater Than button for five seconds. In doing so, “rEAL” is shown in the display. The device then automatically moves to the set start position, performs the desired step and saves the time required to do this. The time that is measured is the controlled movement from start position to target position. After the succesful measurement, this reference step time is shown in the display in the form: “###.#” seconds. If a reference step is attempted without previous initialization of the device, “noini” appears in the display. If the start position cannot be approached or if the jump destination cannot be reached, “Fdini“ (Failed PST Initialization) is displayed. A7.FACT1 Factor 1 Input of the factor for the threshold 1 error message. The factor 1 refers to the reference step time. If a specified partial stroke test results e.g. in a reference step time of 1.0 second and factor 1 is used in the factory setting of 1.5, the threshold 1 error message of the partial stroke test is performed for a measuring time of 1.5 seconds. A8.FACT2 Factor 2 Input of the factor for the threshold 2 error message. The factor 2 refers to the reference step time. If a specified partial stroke test results e.g. in a reference step time of 1.0 second and factor 2 is used in the factory setting of 3.0, the threshold 2 error message of the partial stroke test is performed for a measuring time of 3.0 seconds. A9.FACT3 Factor 3 Input of the factor for the threshold 3 error message. The factor 3 refers to the reference step time. If a specified partial stroke test results e.g. in a reference step time of 1.0 second and factor 3 is used in the factory setting of 5.0, the threshold 3 error message of the partial stroke test is performed for a measuring time of 5.0 seconds. At the same time, if this time threshold is exceeded, the excitation signal of the actuator is cancelled to prevent any sudden breaking free and overshooting of a valve that might be jammed or rusted in place. The partial stroke test is thus stopped immediately, a threshold 3 error is reported and the actuator is moved back to its original position. SIPART PS2 Manual A5E00074631--06 111 Operation b. DEVI General control valve malfunction This parameter activates the dynamic monitoring of the control valve reaction. To do this, the actual position sequence is compared to the guide value and the expected position sequence, which allows conclusions with regard to the correct operational behavior of the control valve. When the parameter is activated, the submenu for the general control valve malfunctions from b1 to b5 opens. The function can be configured there. b1.TIM Time constant of the low-pass filter The time constant of the low-pass filter is determined during the automatic initialization of the device. In the factory setting, parameter b1 therefore indicates “Auto”. If the user is very familiar with the process sequence or desires a certain filter time constant for application-specific reasons, parameter b1 can be set from one second to 400 seconds manually. One second causes no damping, 400 seconds result in a strong damping effect. b2.LIMIT Limit for the general control valve malfunction Sets the limit for the deviation from the model behavior. This limit is a reference value for the error message factors. Factory setting is 1.0 %. b3.FACT1 Factor 1 Input of the factor for the threshold 1 error message. This factor refers to the limit for the general control valve malfunction. Factory setting for factor 1 is 5.0. That means, for b2.LIMIT = 1.0% and factor 1 = 5.0, the first error message is triggered at a control deviation of 5.0 % from the model behavior. b4.FACT2 Factor 2 Input of the factor for the threshold 2 error message. This factor refers to the limit for the general control valve malfunction. Factory setting for factor 2 is 10.0. That means, for b2.LIMIT = 1.0% and factor 2 = 10.0, the second error message is triggered at a control deviation of 10.0 % from the model behavior. b5.FACT3 Factor 3 Input of the factor for the threshold 3 error message. This factor refers to the limit for the general control valve malfunction. Factory setting for factor 3 is 15.0. That means, for b2.LIMIT = 1.0% and factor 3 = 15.0, the third error message is triggered at a control deviation of 15 % from the model behavior. 112 SIPART PS2 Manual A5E00074631--06 Operation C. LEAK Pneumatic leakage This parameter is used to activate the function for the detection of a pneumatic leakage. To do so, the changes of position and the internally used controller output are recorded and filtered, depending on the direction. The filter result provides a coefficient that allows the detection of any leakage. Note that the detection of a leak can only provided clear results for spring-loaded actuators. C1.LIMIT Limit for the leakage indicator Sets the limit for the leakage indicator The leakage indicator is scaled within the range of 0.0 to 100.0. Factory setting for the limit is 30.0. In other words, there is leakage below this limit. A leak can be expected if this value is exceeded. To be able to make full use of the sensitivity of the detection process, it is recommended to perform a ramp test with a calibrator after the automatic initialization of the device. The ramp should cover the standard operating range of the valve and correspond in steepness to the approximate dynamic requirements of the application. During the ramp test, parameter 15.ONLK of the diagnosics menu provides information on the values shown by the leakage indicator. This allows the limit for the leakage coefficient to be defined above the maximum ramp test value. C2.FACT1 Factor 1 Input of the factor for the threshold 1 error message. This factor refers to the limit for the leakage indicator. Factory setting for factor 1 is 1.0. That means, for C1.LIMIT = 30.0 and factor 1 = 1.0, the first leakage error message is triggered at a leakage indication of 30.0. C3.FACT2 Factor 2 Input of the factor for the threshold 2 error message. This factor refers to the limit for the leakage indicator. Factory setting for factor 2 is 1.5. That means, for C1.LIMIT = 30.0 and factor 2 = 1.5, the second leakage error message is triggered at a leakage indication of 45.0. C4.FACT3 Factor 3 Input of the factor for the threshold 3 error message. This factor refers to the limit for the leakage indicator. Factory setting for factor 3 is 2.0. That means, for C1.LIMIT = 30.0 and factor 3 = 2.0, the third leakage error message is triggered at a leakage indication of 60.0. SIPART PS2 Manual A5E00074631--06 113 Operation d. STIC Slipstick effect This parameter is used to activate the function for the detection of a slipstick effect. The device tries to detect sudden changes of the valve position that indicate excess slipstick. If the device detects a slipstick, the filtered step is saved as slipstick value. When the valve moves normally again (without detection of a slipstick), the slipstick value is reduced slowly. Note that to avoid misinterpretations, for actuators with actuating times below 1 s, the positioner cannot distinguish reliably between a normal movement and a sudden change. d1.LIMIT Limit for the slipstick detection Sets the limit for a step caused by a slipstick effect. The limit can be set within the range of 0.0 to 100.0%. Factory setting for the limit is 1.0. d2.FACT1 Factor 1 Input of the factor for the threshold 1 error message. This factor refers to the limit for the slipstick detection. Factory setting for factor 1 is 2.0. That means, for d1.LIMIT = 1.0 and factor 1 = 2.0, the first slipstick error message is triggered when the current slipstick value has reached 2.0. d3.FACT2 Factor 2 Input of the factor for the threshold 2 error message. This factor refers to the limit for the slipstick detection. Factory setting for factor 2 is 5.0. That means, for d1.LIMIT = 1.0 and factor 2 = 5.0, the second slipstick error message is triggered when the current slipstick value has reached 5.0. d4.FACT3 Factor 3 Input of the factor for the threshold 3 error message. This factor refers to the limit for the slipstick detection. Factory setting for factor 3 is 10.0. That means, for d1.LIMIT = 1.0 and factor 3 = 10.0, the third slipstick error message is triggered when the current slipstick value has reached 10.0. 114 SIPART PS2 Manual A5E00074631--06 Operation E. DEBA Dead zone monitoring This parameter activates the monitoring of the dead zone adaptation. Prerequisite for the function is the setting of parameter “34.DEBA” = Auto. E1.LEVL3 Threshold for the monitoring of the dead zone adaptation. This value (%) can be used for the automatic adaptation of the dead zone. If the dead zone exceeds the set value, the threshold 3 error message is triggered. The three-level error message is not implemented for dead zone monitoring. F. ZERO Zero point offset This function is for detecting when the lower stop has changed its value compared to the value during initialization by more than the set thresholds. Monitoring is only possible if the valve is within the tight closing function. The activation of the “bottom tight closing function” (parameter “39.YCLS”) is therefore prerequisite. F1.LEVL1 Threshold 1 First threshold for monitoring the lower limit stop. If the set absolute value is exceeded during “bottom tight closing”, this will trigger the threshold 1 error message. F2.LEVL2 Threshold 2 Second threshold for monitoring the lower limit stop. If the set absolute value is exceeded during “bottom tight closing”, this will trigger the threshold 2 error message. F3.LEVL3 Threshold 3 Third threshold for monitoring the lower limit stop. If the set absolute value is exceeded during “bottom tight closing”, this will trigger the threshold 3 error message. SIPART PS2 Manual A5E00074631--06 115 Operation G. OPEN Shifting the upper stop This function is for detecting when the upper stop has changed its value compared to the value during initialization by more than the specified tolerance value. Monitoring is only possible if the valve is within the tight closing function. The activation of the “top tight closing function” (para“meter “39.YCLS”) is therefore prerequisite. G1.LEVL1 Threshold 1 First threshold for monitoring the upper limit stop. If the set absolute value is exceeded during “top tight closing”, this will trigger the threshold 1 error message. G2.LEVL2 Threshold 2 Second threshold for monitoring the upper limit stop. If the set absolute value is exceeded during “top tight closing”, this will trigger the threshold 2 error message. G3.LEVL3 Threshold 3 Third threshold for monitoring the upper limit stop. If the set absolute value is exceeded during “top tight closing”, this will trigger the threshold 3 error message. . NOTE Monitoring of the lower and upper limit stops does not only react to valve faults. A misadjustment of the position feedback is also detected as a malfunction if the threshold values are exceeded. 116 SIPART PS2 Manual A5E00074631--06 Operation H. TMIN Monitoring of the lower temperature limit The current temperature in the positioner housing is measured by a sensor on the electronic circuit board. This parameter is for the three-level monitoring of the lower temperature limit. H1.TUNIT Temperature unit The temperature unit can be switched over by pressing the Greater Than or Smaller Than button between °C and °F. Another way of switching over is the J1.TUNIT parameter for monitoring the upper temperature limit. The selected unit applies to all temperature-related parameters. H2.LEVL1 Threshold 1 First threshold for monitoring the lower temperature limit. The factory setting is --25.0 °C. If the temperature falls below the set value, the threshold 1 error message is triggered. H3.LEVL2 Threshold 2 Second threshold for monitoring the lower temperature limit. The factory setting is --30.0°C. If the temperature falls below the set value, the threshold 2 error message is triggered. H4.LEVL3 Threshold 3 Third threshold for monitoring the lower temperature limit. The factory setting is --40.0°C. If the temperature falls below the set value, the threshold 3 error message is triggered. SIPART PS2 Manual A5E00074631--06 117 Operation J. TMAX Monitoring of the upper temperature limit The current temperature in the positioner housing is measured by a sensor on the electronic circuit board. This parameter is for the three-level monitoring of the upper temperature limit. J1.TUNIT Temperature unit The temperature unit can be switched over by pressing the Greater Than or Smaller Than button between °C and °F. Another way of switching over is the H1.TUNIT parameter for monitoring the lower temperature limit. The selected unit applies to all temperature-related parameters. J2.LEVL1 Threshold 1 First threshold for monitoring the upper temperature limit. The factory setting is 75.0°C. If the temperature exceeds the set value, the threshold 1 error message is triggered. J3.LEVL2 Threshold 2 Second threshold for monitoring the upper temperature limit. The factory setting is 80.0°C. If the temperature exceeds the set value, the threshold 2 error message is triggered. J4.LEVL3 Threshold 3 Third threshold for monitoring the upper temperature limit. The factory setting is 90.0°C. If the temperature exceeds the set value, the threshold 3 error message is triggered. 118 SIPART PS2 Manual A5E00074631--06 Operation L. STRK Monitoring of the displacement integral This parameter activates the monitoring of the displacement integral. This function allows the preventive maintenance of the control valve, also see chapter 4.5 “Diagnosics”, page 122. L1.LIMIT Limit for the number of strokes Input of the limit for the number of strokes. The parameter can be used depending on the requirement profile of the user. On the one hand, it is possible to enter a maximal number for the strokes and to use factors smaller than one to receive warning messages when a certain fraction of the maximal number is reached. On the other hand, a minimum value can be entered for the strokes. Factors greater than one are then used to receive warning messages for certain limits above the minimum value. Factory setting for the limit is 1 000 000. L2.FACT1 Factor 1 Input of the factor for the threshold 1 error message. This factor refers to the limit for the number of strokes. Factory setting for factor 1 is 1.0. That means, for L1.LIMIT = 1 000 000 and factor 1 = 1.0, the first stroke counter error message is triggered after 1 000 000 strokes. L3.FACT2 Factor 2 Input of the factor for the threshold 2 error message. This factor refers to the limit for the number of strokes. Factory setting for factor 2 is 2.0. That means, for L1.LIMIT = 1 000 000 and factor 2 = 2.0, the second stroke counter error message is triggered after 2 000 000 strokes. L4.FACT3 Factor 3 Input of the factor for the threshold 3 error message. This factor refers to the limit for the number of strokes. Factory setting for factor 3 is 5.0. That means, for L1.LIMIT = 1 000 000 and factor 3 = 5.0, the third stroke counter error message is triggered after 5 000 000 strokes. SIPART PS2 Manual A5E00074631--06 119 Operation O.

O3.FACT2 Factor 2 Input of the factor for the threshold 2 error message. This factor refers to the limit for the number of changes of direction. Factory setting for factor 2 is 2.0. That means, for O1.LIMIT = 1 000 000 and factor 2 = 2.0, the second direction change error message is triggered after 2 000 000 strokes. O4.FACT3 Factor 3 Input of the factor for the threshold 3 error message. This factor refers to the limit for the number of changes of direction. Factory setting for factor 3 is 5.0.

PAVG Calculation of the position average This parameter is used to activate the function for the calculation of the position average. The function allows the calculation of a reference average for the position sequence within preset intervals and the calculation of comparison average values for the following intervals. If the comparison average values deviate from the reference average, error messages are displayed, depending on the set thresholds. 120 SIPART PS2 Manual A5E00074631--06 Operation P1.TBASE Time basis for the formation of the average value Sets the intervals for the formation of the average value. The following time intervals are available: 30 minutes 8 hours 5 days 60 days 2.5 years P2.STATE Status of the calculation of the position average After activating the function with parameter P. PAVG, the initial status of the calculation of the position average is “IdLE” (inactive). To start the calculation of the position average, the Greater Than button is pressed for five seconds. The display text then switches from “IdLE” to “rEF” (reference average is calculated) and remains there until the selected time interval has passed. The reference average is then shown on the display. . NOTE The current comparison average is displayed in the diagnosis menu under parameter 19.PAVG as soon as the first comparison interval has passed. During the first comparison interval, “COMP” (comparison interval) is displayed there. P3.LEVL1 Threshold 1 First threshold for monitoring the reference average. The factory setting is 2.0%. If a comparison average deviates from the reference by more than this value, the threshold 1 error message is triggered. P4.LEVL2 Threshold 2 Second threshold for monitoring the reference average. The factory setting is 5.0%. If a comparison average deviates from the reference by more than this value, the threshold 2 error message is triggered. P5.LEVL3 Threshold 3 Third threshold for monitoring the reference average. The factory setting is 10.0%. If a comparison average deviates from the reference by more than this value, the threshold 3 error message is triggered.

With manual initialization, the values of the manually approached end positions can be found here. 22 IMPUP 23 IMPDN Pulse length up and Pulse length down During the initialization phase, the smallest pulse lengths are determined, with which a movement of the actuator can be achieved. They are determined separately for the “Up” direction and the “Down” direction and displayed here. These two parameters can be set for special applications (see chapter 4.7, page 143). 24 DBUP 25 DBDN Dead zone up and Dead zone down The dead zone of the controller in “Up” direction or in “Down” direction is displayed here. The values correspond either to the manually set value of parameter “34.DEBA” or to the value automatically adapted by the device if “DEBA” was set to “Auto”. 128 SIPART PS2 Manual A5E00074631--06 Operation Short step zone up and Short step zone down 26 SSUP 27 SSDN The short step zone is the range of the controller, in which pulseshaped excitation signals are output. The pulse length is proportional to the control deviation. If the control deviation is not within the short step zone, then the valves are activated in permanent contact. These two parameters can be set for special applications (see chapter 4.7, page 143). Current temperature 28 TEMP Current temperature in the positioner housing. The sensor is on the electronic circuit board. The temperature display can be switched between _C and _F by pressing the decrement button. Minimum temperature (min/max pointer) and Maximum temperature (min/max pointer) 29 TMIN 30 TMAX The minimum and maximum temperature in the housing interior is determined continuously in the form of a min/max pointer and saved and can only be reset at the factory. 31 T1 to 39 T9 Number of operating hours in temperature range T1 to T9 The device gives statistical information as to how long and in which temperature ranges it was operated. For this purpose, the measured temperature is averaged for each hour and the counter that is assigned to the relevant temperature range is incremented every hour. This allows conclusions to be made about past operating conditions of the device and the entire control valve. The temperature ranges are divided as follows: T1 Temperature range [_C] ≥--30 40 VENT1 41 VENT2 T2 ≥--30 <--15 T3 ≥--15 <0 T4 ≥0 < 15 T5 ≥15 < 30 T6 ≥30 < 45 T7 ≥45 < 60 T8 ≥60 < 75 T9 ≥75 Number of switching operations pilot valve 1 and Number of switching operations pilot valve 2 These two counters add up the activation processes of the pilot valves and are for the assessment of the switching dependency. SIPART PS2 Manual A5E00074631--06 129 Operation Save maintenance data 42 STORE for at least 5 seconds triggers a Pressing the increment button memory function. In doing so, the diagnostic data 7 to 18 is saved in a non--volatile memory as the “data of the last maintenance”. This diagnostic data consists of selected values that, when changed, can provide information on the mechanical wear of the valve. Normally, this function is operated via PDM, menu item: Device!Save maintenance info. The comparison of the data of the last maintenance to the current data is possible via PDM. 43 PRUP 44 PRDN Prediction up Prediction down see chapter 4.7, page 143. 45 WT00 to 52 WT95 Number of operating hours in actuating range WT00 to WT95 If the positioner is in automatic mode, statistical information is generated as to how long a valve or a flap was operated in which section of the actuating range. For this purpose, the entire actuating range (0 to 100 %) is divided into 8 sections (actuating ranges). The positioner registers the current position continuously and increments the operating hours counter that is assigned to the relevant section (actuating range) every hour. This allows conclusions to be made about past operating conditions and is in particular for the assessment of the control characteristics of the control loop or of the entire control valve. The actuating range is divided as follows: Actuating range Actuating range section WT00 WT05 WT10 WT30 WT50 WT70 WT90 WT95 <5% ≥5 % < 10 % ≥10 % < 30 % ≥30 % < 50 % ≥50 % < 70 % ≥70 % < 90 % ≥90 % < 95 % ≥95 % The 8 operating hours counters can be set to zero together by pressing the increment button (for at least 5 seconds). TIP: Since the actuating ranges are arranged at the end of the diagnosis menu with numbers 45 to 52, press the decrement button several times in addition to the operating mode button. That is how you access diagnosis numbers 45 to 52 quickly. Setpoint current 53 MA You can have the current setpoint displayed here in mA. . NOTE All diagnosis values are updated every 15 minutes in the non-volatile memory so that only the values of the past quarter of an hour are lost if there is a power failure. 130 SIPART PS2 Manual A5E00074631--06 Operation 4.5.3 Online diagnosis While the positioner is in operation, some important values and parameters are monitored on a continuous basis. In “Configuration” mode, you can configure this monitoring in such a way that the fault message output is activated when a certain event occurs, such as e.g. when a limit is exceeded. Table 4-2, page 133, shows which events can activate the fault message output and the alarm outputs, how the parameters need to be set for this event to be monitored, when the fault messages disappears again and what the possible causes of the malfunction are. In automatic and manual mode, the display shows what triggered the fault message when the fault message output reacts. The two numbers at the bottom left indicate the relevant error code. If several triggers occur simultaneously, they are display in succession cyclically. The device status that also includes all fault messages, can be called using command #48 via HART. The parameters of the extended diagnostics allow error messages to be displayed in one, two or three levels. In addition to the fault message output, alarm outputs 1 and 2 are then used. For this purpose, parameter 51.XDIAG needs to be set according to the following table: Settings of 51.XDIAG Off Message by On1 Fault message output for threshold 3 error messages (one-level) Fault message output for threshold 3 error messages and alarm output 2 for threshold 2 error messages (two-level) Fault message output for threshold 3 error messages and alarm output 2 for threshold 2 error messages and alarm output 1 for threshold 1 error messages (three-level) On2 On3 SIPART PS2 Manual A5E00074631--06 Extended diagnostics not activated 131 Operation Error three- Event code level 1 no Remaining control deviation Parametersetting always active Error message disappears if... ... the control deviation has disappeared again.

Events that can activate the fault message output Explanations for the “Error codes” column: 1 Control deviation monitoring In automatic mode, the deviation between the setpoint and actual value is monitored continuously. According to the setting of parameter 48. TIM, the monitoring time for setting the fault messages, and 49. LIM, the response threshold of the fault message, the fault message is activated if the control deviation remains. As soon as the control deviation falls below the response threshold again, the fault message is cancelled. 2 Automatic mode monitoring If parameter “47. FCT”, the fault message output function, is set accordingly, a fault message is generated if the device is not in automatic mode. In this way, e.g. the control system can be warned if the device was switched to manual mode or configuration on location. 3 Binary input BE1 or BE2 active If parameter “47. FCT”, the fault message output function, and parameter “42.BIN1”, the binary input 1 function, are set accordingly, a fault message is generated when the binary input is activated. This can be e.g. a stuffing box monitoring switch, a temperature switch or a limit switch (e.g. for pressure). Binary input 2 (for the alarm unit option) can be configured in the same way. SIPART PS2 Manual A5E00074631--06 133 Operation 4 5 Stroke number monitoring Monitoring of the number of changes of direction The two values, number of strokes and number of changes of direction, are compared to the threshold values on a continuous basis. These values result from the parameters “L1.LIMIT” to “L4.FACT3” and “O1.LIMIT” to “O4.FACT3”. If they are exceeded, depending on the operating mode of the extended diagnostics, the fault message output reacts, and possibly also the alarm outputs. The two functions can be deactivated by the parameter setting “OFF” for “L. STRK” or “O. DCHG”. 6 7 Monitoring of the lower limit stop (valve seat) Monitoring of the upper limit stop The monitoring of the lower limit stop is activated if parameter “F. ZERO” has a value ¸OFF. This function can be used e.g. to detect valve seat errors. If the limit is exceeded, this can be an indication of deposits or foreign particles on the valve seat. If the limit is fallen short of, wear to the valve seat or reactor body could be the cause. The mechanical misadjustment of the position feedback can also trigger this error message. Monitoring takes place every time the valve is in “bottom tight closing” position. In doing so, the current position is compared to the position that was determined as lower end stop during the initialization phase. The activation of the “bottom tight closing function” (parameter “39.YCLS”) is therefore prerequisite. Example: 3% is set as value. For “bottom tight closing”, the 0% position is normally established. If a value of >3% or <--3% is determined instead, a fault is reported. The fault message remains activated until either a subsequent monitoring process remains within the tolerance range or a re-initialization is carried out. The deactivation of the monitoring process (“F. ZERO”=OFF) also deletes any fault messages. This monitoring function does not provide any useful results if the stops were not determined automatically during initialization but instead the limits were set by hand (manual initialization, “5.INITM”). An appropriate diagnosis was carried out for the upper limit stop. The parameter “G. OPEN” is used to set this limit. The activation of the “top tight closing function” (parameter “39.YCLS”) is therefore prerequisite. 8 Dead zone adaptation monitoring If, during the automatic adaptation of the dead zone (parameter 34.DEBA=Auto) the dead zone increases disproportionately during operation, this is an indication of a fault in the system (e.g. significantly increased stuffing box friction, play in the position displacement sensor, leakage). Therefore a limit can be specified for this value (“E1.LEVL3”, threshold for dead zone monitoring) that activates the fault message output if it is exceeded. 134 SIPART PS2 Manual A5E00074631--06 Operation 9 Partial stroke test exceeds reference step time This error message appears on the one hand if a manual or cyclic partial stroke test is triggered and the test cannot be started because the valve is not within the start tolerance range. The error message also appears if one of the three thresholds of the partial stroke test that are a result of the reference step time (A6.PSTIN) times factors (A7.FACT1 to A9.FACT3) is violated. How serious the error message is, can be seen at the bar graph on the right side of the display. At the same time, the severity of the error message is output via the fault message output or the alarm outputs, according to the operating mode of the extended diagnostics. 10 General control valve malfunction The monitoring of the operational behavior triggers if the actual valve position leaves a narrow corridor between guide value and expected position sequence. In this case, the deviation between expected and actual position sequence is filtered and output and compared to the set thresholds that are the result of the limit (b2.LIMIT) times the factors (b3.FACT1 to b5.FACT3). 11 Pneumatic leakage This error message appears if the leakage indicator exceeds the set thresholds. Note that the function can only take effect with its entire sensitivity if a ramp test is performed to set the leakage indicator after initialization (see Explanations on C1.LIMIT). 12 Slipstick effect too high If the slipstick of the control valve is increased during operation of if an increasing number of slip jumps are detected, the relevant limits can be exceeded, resulting in an error message. 13 Temperature fallen short of This error message appears if the lower temperature limit thresholds are fallen short of. 14 Temperature exceeded This error message appears if the upper temperature limit thresholds are exceeded. 15 Monitoring of the position average If a position average is calculated when a comparison interval passes that deviates from the reference value by more than the set thresholds, this error message triggers.

In special cases (e.g. extremely small and therefore particularly fast actuators or for operation with boosters), you might want to modify this data specifically for faster compensation or a greater damping effect. The following six parameters are available for this purpose: 13 Pulse length up 14 Pulse length down This is for defining the smallest pulse lengths with which the actuator is to move for each actuating direction. The optimal value mainly depends on the volume of the actuator. Small values result in small actuating increments and frequent activation of the actuator. Bear in mind that if the values are too small, there will be no movement. Large values are advantageous for large actuator volumes. Also bear in mind that large actuating increments for small actuators also result in large movements. 17 Short step zone up 18 Short step zone down The short step zone is the range of the control deviation between the fast step zone and the dead band in which the actuator is activated by pulses. In the case of small control deviations, small values already cause relatively high actuating speeds and can therefore result in overshooting. Large values in particular reduce overshooting in the case of large changes in the nominal value and result in slow actuating speeds near the compensated status. 34 Prediction up 35 Prediction down This parameter has the same effect as a damping factor and is used to set the control dynamics. Small values cause fast compensation with overshooting. Large values cause slow compensation without overshooting. We recommend that you perform an automatic initialization first and only then adapt the parameter determined by the positioner to your own special requirements. TIP: To have a fixed reference value, it is helpful if you specify a fixed value for the dead zone (DEBA parameter) instead of “Auto” for the optimization of your particular controller. You select the parameters above from the diagnosis menu in the accustomed manner and activate the joint adjustment by pressing the increment or decrement button for 5 seconds. If you now adjust the relevant parameter, the new value is activated immediately. You can test the effects of the new values on the controller results immediately. When you quit the diagnosis menu, the parameter adjustment option is deactivated again. SIPART PS2 Manual A5E00074631--06 143 Operation 144 SIPART PS2 Manual A5E00074631--06 Care and Maintenance Service and Maintenance 5 The positioner is largely maintenance-free. The positioners are fitted with filters in the pneumatic connections as protection against coarse particles of dirt. If the pneumatic energy supply contains particles of dirt, the filters may clog and impair the function of the positioner. In this case the filters can be cleaned as follows. Positioner in metal housing and explosion proof version 1. Switch off the pneumatic power supply and remove the pipes. 2. Remove the metal filters carefully from the holes and clean (e.g. with compressed air). 3. Insert the filters. 4. Re-connect the pipes and supply pneumatic energy. Positioner in plastic housing Removal 1. Switch off the pneumatic power supply and remove the pipes. 2. Unscrew the cover 3. Remove the three screws from the pneumatic connector strip. 4. Remove the filters and O-rings behind the connector strip. 5. Clean the filters (e.g. with compressed air). Installation 6. First insert the filters in the recesses in the plastic housing and then place the O-rings on the filters. 7. Align the pneumatic connector strip on the two lugs and screw tight with the three self--tapping screws. Important: Make sure that the same thread is used. To do this turn the screws counterclockwise until they snap into the thread audibly. Only then should you tighten the screws. SIPART PS2 Manual A5E00074631--06 145 Care and Maintenance 8. Replace the cover and screw it tight. 9. Re-connect the pipes and supply pneumatic energy. ! Repair/Upgrade DANGER Electrostatic charging must be prevented in hazardous areas. These could be caused by example when cleaning the positioner in plastic housing with a dry cloth. Faulty equipment should be sent to the repair department with details of the fault and its origin.
