must be observed. Laws and regulations valid in your country must be
observed for the electrical installation in explosions hazardous areas.
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).
It should be checked whether the available power supply, insofar as
this is required, is compliant with the power supply specified on the
rating plate and specified in the examination certificate valid in your
country.
Take care to avoid electrostatic discharges within the hazardous area,
such as can arise if a dry cloth is used to clean the positioner in the
plastic housing.
Devices with the protection type “flameproof enclosure” may only be
opened when the power is off.
!WARNING
Devices with the protection type “intrinsically safe” lose their certifica-
tion as soon as they are operated with circuits that do not conform to

Design and Method of Operation
The following chapter describes the mechanical and electrical design,
the instrument components and method of operation of the positioner.
2.1 Overview
The electropneumatic positioner forms a control system in connection
with an actuator. 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 hous-
ing cover removed.
The standard controller has one digital input (DI1). This can be config-
ured 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=4to20mA.
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 addi-
tionally through a fault message output. The value of the control differ-
ence 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-
Introduction

Design and Functional Principle
16 SIPART PS2 Manual
A5E00074631--06
spond even when the power supply fails or the electronics are defec-
tive.
The actuator can also be blocked or driven to its final positions depend-
ing 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 explosion-
proof version, must not be adjusted.

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.

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 posi-
tion 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 fre-
quency. 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.

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 hand-
held communicatorR, PC or programming unit. This enables you to
configure your instrument comfortably, save configurations, call diag-
nostic data, display online measured values and much more. Commu-
nication takes place as frequency modulation over the existing signal
lines for the command variable from 4 to 20 mA.
The SPART PS2 is integrated in the following parameterization tools:
SHandheld communicatorR
SPDM (Process Device Manager)
SAMS (Asset Management System)
SCornerstone (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.

The following option modules are available for the positioner in the ex-
plosion-proof version:
-- Iy-module
-- Alarm module
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 elec-
tronics 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.
See figure 2-12, page 31. Disconnect or isolate the power supply
cables first.

Insert the Iymodule (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
S3 digital outputs and
S1 digital input
The digital outputs serve to output fault messages and alarms. The
configuration is described in chapter 4.4, page 95, with the para-
meters 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:
Sexplosion protected for connecting to switching amplifier
EN 60947-5-6
Snon-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.
Sone potential isolated for voltage level
Sone not potential isolated for floating contacts
These two inputs are designed as logic OR links.
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 mother-
board (see figure 2-11, page 28).

2.7.5 SIA module
The SIA module contains:
Sone binary output
Stwo binary outputs
A collected fault message (see alarme module) is output via the binary
output. The floating digital output is implemented as a self error report-
ing 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.
(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 bea-
ring and the special screw must then be turned simultaneously so that
the pins slot into the special screw.
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 correspond-
ing 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).

9. Make all the electrical connections between the motherboard and
the options with the ribbon cables provided and between the mo-
therboard 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 termi-
nals 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 sig-
nal 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 opera-
ting, they are relatively sluggish. The following remedy might be of help
if you are having trouble with the adjustment: open and close the ac-
tuator several times while holding the actuating discs. This temporarily
reduces the friction. This allows an easier and finer adjustment.

2.7.6 Mechanical limit switch module
The mechanical limit switch module contains the following:
SA binary output for the output of a group error message)
STwo switches for signaling two limit values that can be set mechani-
cally. These two switches are electrically independent from the rest
of the electronic system.
The installation has to be carried as follows (figure 2-11, page 28):
!WARNING
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.
!DANGER
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 ca-
ble 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.

!WARNING
To avoid injury or mechanical damage to the positioner/mounting kit,
the following order must be observed for assembly:
1. Mechanical fitting of positioner this chapter
2. Connection of electric power supply see chapter 3.4, p. 57
3. Connection of pneumatic power supply see chapter 3.5, p. 71
4. Put into operation see chapter 3.6, p. 72
Please also observe the warning on page 58!
General
Preparing for Operation
44 SIPART PS2 Manual
A5E00074631--06
.NOTE
The positioner will be equipped at the factory and delivered complete
with the necessary options at the customer’s request. Options modules
may only be retrofitted by our service technicians.
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 poten-
tially 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 particu-
larly important when operating the positioner at low ambient tempera-
tures. Please set the purge air switch (on the valve block above the

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.
Preparing for Operation

SIPART PS2 Manual
A5E00074631--06
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:
Sscrew-type gland with sealing ring (e.g. FESTO: CK –1 / 4–PK–6)
Splastic hose approx. 20 to 30 cm (e.g. FESTO PUN- 8X1,25 SW)
Scable straps (number and length depends on local conditions)
Procedure
SConnect 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 posi-
tioner.
SCheck the electrical connections for perfect firm contact.
SCheck the seal in the housing cover for damage and contamination.
Clean and replace if necessary.
SMount the positioner if possible so that the sinter bronze silencer
faces downwards on the underside of the housing (vertical installa-
tion position). If this is not possible, the silencer should be replaced
by a suitable screw-type gland with a plastic hose.
Preparing for Operation
46 SIPART PS2 Manual
A5E00074631--06
Assembly of the screw-type gland with plastic hose
SUnscrew the sinter bronze silencer from the exhaust air opening on
the underside of the housing.
SScrew the screw-type gland mentioned above into the exhaust air
opening.
SMount the above mentioned plastic hose on the screw-type gland
and check the good fit.
SFix the plastic hose with a cable strap to the fitting so that the open-
ing faces downwards.
SMake 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 explosion-
proof 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 re-
quired if extreme acceleration or strong vibration might be present
within your process.
Preparing for Operation
47
SIPART PS2 Manual
A5E00074631--06
Procedure After you have installed the positioner and put it fully into operation, you
can set the torque for the friction clutch as follows:
SOn the module cover, insert an ordinary 4 mm wide screwdriver into
a slot on the yellow wheel.
SNow 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.
SYou can recognize a locked friction clutch by an approx. 1 mm wide
gap between the yellow and black wheels.
SIf 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 trans-
mission ratio selector as follows:
SAdjust 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.
SPlease 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).

Applications in which the measures described above are inadequate
are also conceivable. 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:
SThe 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.
Sor a Non-Contacting Position Sensor (e.g. 6DR4004-6N).
SThe controller unit, any positioner version.
SThe 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.
SA 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 k)isto
be used instead of the position detection system C73451-A430-D78.
!WARNING
The explosion-proof version may not be run together with the external
position detection system.

3.3.4 Assembly procedure (see figure 3-7, page 51)
1. Mount clamping assembly (3) with hexagon socket cap screws
(17) and lock washer (16) on the actuator spindle.
2. Insert the pick-up bracket (2) into the recesses of the clamping
assembly. Set the necessary length and tighten the screws so that
the pick-up bracket can still be shifted.
3. Insert the pin (4) in the lever (6) and assemble with nut (18), spring
washer (14) and washer (12).
4. The value of the stroke range specified on the actuator or if this
does not exist as a scaling value, the next greatest scaling value is
set. The center of the pin must be in line with the scaling value.
The same value can be set later under parameter 3.YWAY in
commissioning to display the way in mm after initialization.
5. Assemble the hexagon socket cap screw (17), spring washer (16),
washer (12) and square nut (19) on the lever.
6. Push the premounted lever onto the positioner axis up to the stop
and fix with the hexagon socket cap screw (17).
7. Fit the mounting bracket (1) with two hexagon head screws (9),
lock washer (10) and flat washer (11) on the rear of the positioner.
8. Selection of the row of holes depends on the width of the actuator
yoke. The pin (4) should engage in the pick-up bracket (2) as close
as possible to the spindle but may not touch the clamping
assembly.
9. Hold the positioner with the mounting bracket on the actuator so
that the pin (4) is guided within the pick-up bracket (2).
10. Tighten the pick-up bracket.
11. Position the mounting parts according to the type of actuator.
-- Actuator with ledge: Hexagon head screw (8), flat washer (11)
and lock washer (10).
-- Actuator with plane surface: Four hexagon head screws (8), flat
washer (11) and lock washer (10).
-- Actuator with columns: Two U bolts (7), four hexagon nuts (21)
with flat washer (11) and lock washer (10).
12. Secure positioner onto the yoke using the previously positioned
mounting parts.
.NOTE
Set the height of the positioner so that the horizontal lever position is
reached as close to the stroke center as possible. You can use the
lever scale as orientation. It must be guaranteed that the horizontal
lever position is passed through within the stroke range.

.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 haz-
ardous 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
Preparing for Operation
58 SIPART PS2 Manual
A5E00074631--06
!WARNING
If the intrinsically safe version is operated with a higher operating vol-
tage 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 con-
nect at least one of these bushes with grounded fittings by electrically
conductive (blank) mounting parts.

A5E00074631--06
.NOTE
Use standard M20 x 1.5 cable gland nuts to ensure leakage (IP-protec-
tion 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 discon-
nected under power in normal operation.
However, during installation or repair work the positioner may be con-
nected 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.

3.5 Pneumatic Connection
!WARNING
For reasons of safety, the pneumatic power may only be supplied after
assembly when the positioner is switched to operating level P manual
operation with electrical signal applied (as-delivered state, see
figure 4-4, page 92).
.NOTE
Note the air quality! Oil-free industrial air, solid content < 30 μm, pressure
dew point 20 K below the lowest ambient temperature (chapter 7 “Techni-
cal Data”, page 153).
SConnect a manometer block for supply air and actuating pressure if
necessary.
SConnection by female thread G 1/4 DIN 45141 or 1/4” NPT:
PZSupply air 1.4 to 7 bar
Y1 Actuating pressure 1 for single- and double-acting actuators
Y2 Actuating pressure 2 for double-acting actuators
E Exhaust air outlet (remove silencer if necessary)
see figure 2-4 and 2-5, page 19.
SSafety position when the electric power supply fails:
single-acting: Y1 deaerated
double-acting: Y1 Max. Actuating pressure
(supply air pressure)
Y2 deaerated
SConnect actuating pressure Y1 or Y2 (only in double-acting actua-
tors) according to the desired safety position.
SConnect supply air to PZ.
.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.

72 SIPART PS2 Manual
A5E00074631--06
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 actua-
tor 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:
SAutomatic initialization
Initialization takes place automatically. Hereby the positioner deter-
mines the direction of action, the stem travel and the angle of rota-
tion, the travel times of the actuator one after the other and adapts
the control parameters to the dynamic behavior of the actuator.
SManual initialization
The stem travel or angle of rotation of the actuator can be set
manually, the other parameters are determined as in automatic init-
ialization. This function is useful in actuators with soft limit stops.
SCopying initialization data (positioner exchange)
In the devices with HART function the initialization data of a posi-
tioner can be read out and copied to another positioner. This en-
ables 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 initializa-
tion. 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 permis-
sible 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.

3.6.1 Preparations for linear actuators
1. Assemble the positioner with the appropriate mounting kit
(see chapter 3.3.3, page 39).
.NOTE
Particularly important is the position of the transmission ratio selec-
tor (8, figure 2-2, page 17) in the positioner:
Stroke Lever Position of the transmission ratio
selector
5to20mm short 33°(i.e. down)
25 to 35 mm short 90°(i.e. up)
40 to 130 mm long 90°(i.e. up)
2. Push the carrier pin (4, figure 3-7 (page 51) 2) onto the lever
(6, figure 3-7, 2) to the scale position corresponding to the rated
stroke or next highest position and screw the carrier pin tight with
the nut (18, figure 3-7, 2).
3. Connect the actuator and the positioner with the pneumatic lines
and supply pneumatic power to the positioner (figure 2-4 and 2-5,
page 19).
4. Connect a suitable current or voltage source (see figure 3-13,
page 59 and figure 3-20, page 63).
5. The positioner is now in the operating mode “P-manual opera-
tion The current potentiometer voltage (P) is displayed in percent
in the top line of the display, e.g.: P12.3”, and “NOINI” flashes in
the bottom line:
6. Check the free running of the mechanics in the whole actuating
range by moving the actuator with the keys and and driving
to the respective end position.
.NOTE
You can move the actuator quickly by pressing the other direction key
additionally whilst keeping the direction key selected first pressed.
7. Now move the actuator to the horizontal position of the lever.
A value between P48.0 and P52.0 should be visible in the display.
If this is not the case, adjust the friction clutch (8, figure 2-11, page
28 or in frameproof enclosure 8, figure 2-12, page 31) until “P50.0
is displayed with a horizontal lever. The more accurately you hit
this value, the more exactly the positioner can determine the path.

3.6.3 Manual initialization of linear actuator
The positioner can be initialized with this function without the actuator
being driven hard against the limit stop. The start and end positions of
the travel are set manually. The other initialization steps (optimization
of the control parameters) run automatically as in automatic initializa-
tion.
1. Make preparations as described in chapter 3.6.1, page 73 for

“RUN5” appear one after another in the bottom line of the display.
The following display appears on successful completion of initiali-
zation:
The first line additionally contains the determined stroke in millimeters if
the set lever length was specified with parameter 3 YWAY.

3.7 Copying initialization data (positioner exchange)
With this function you have the possibility of starting up a positioner
without running the initialization routine. This allows for example a posi-
tioner 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 rela-
ted maintenance data may show deviations in particular. Therefore
initialization must be performed at the earliest opportunity.

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 fur-
ther 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.

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 init-
ialization.
To go to the Configuration menu, press the operation mode key for
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.

Figure 4-5 Overview: Configuration
In this operating mode you can move the actuator with the decrement
() and increment keys ( ) and the current position is held regard-
less 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.
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.
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.

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 ap-
pears in the display. The function of the parameter is described briefly

Normally adjustment of the first three following parameters is com-
pletely 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.
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:
SYFCT = turn
This adjustment is necessary for the part-turn actuator.
If “turn” is selected, the following parameter “2. YAGL” is automati-
cally set to 90_and cannot be changed.
SYFCT = 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 move-
ment 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.
SYFCT = 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.
SYFCT = ncSt
Use this when an NCS is fitted to a part-turn actuator.
SYFCT = -ncSt
This must be set when an NCS is used with a part-turn actuator with
reverse direction of control action.
SYFCT = ncSL
This must be set when an NCS is used with a linear actuator.
1.YFCT
Operation
99
SIPART PS2 Manual
A5E00074631--06
SYFCT = ncSLL
This must be adjusted if an NCS is to be connected to a linear ac-
tuator with the position converted by an arm into a part--turn move-
ment.
.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
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:
S33°for strokes 20 mm
S90°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
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 trans-
mission. The carrier must be set to the value of the actuator stroke,
if this is not scaled to the next highest scaled value.

Automatic initialization (see chapter 3.6, page 72)
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
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.
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).
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”.
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.

Setpoint ramp UP
and
Setpoint ramp DOWN
The setpoint ramp is effective in automatic operation and limits the
speed of alteration of the active setpoint. When switching over from
manual operation to automatic the active setpoint is adjusted to the set-
point 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 deter-
mined during initialization is used for the setpoint ramp. TSDO is then
ineffective.

Dead zone of the controller
At dEbA = AUto the dead zone in automatic operation is adapted con-
tinuously 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)
With the parameters “YA” and “YE” the mechanical actuating distance
(from stop to stop) is limited to the set values. In this way the mechani-
cal 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.
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 feed-
back via the current output (MPOS or FLOW).
The MPOS scaling shows the mechanical position (0 to 100%) be-
tween the hard stops of the initialization. This is not affected by the pa-
rameters “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 be-
tween “35.YA” and “36.YE”. The setpoint w (0 to 100%) is always re-
ferred 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 ap-
propriate scale on the display.

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”.

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.

ure) with the parameters “48. TIM” and “49. LIM”

Monitoring time for setting the fault messages
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
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

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.
Start position
The start position of the partial stroke test is specified here within the
range of 0.0 to 100.0%.
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%.
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%.
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.

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.
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.
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.
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.

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.
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.
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 %.
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.
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.
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.

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.
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.
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.
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.
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

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.
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.
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.
Factor 2
Input of the factor for the threshold 2 error message. This factor refers

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 imple-

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”

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.

Save maintenance data
Pressing the increment button for at least 5 seconds triggers a
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.

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:

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, para-
meter 51.XDIAG needs to be set according to the following table:
Settings of 51.XDIAG Message by

Table 4-2 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.

134 SIPART PS2 Manual
A5E00074631--06
4 Stroke number monitoring
5 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 Monitoring of the lower limit stop (valve seat)
7 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.

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.

4.7 Optimizing the controller data
The data for the control quality that was automatically determined
during initialization is optimized for short compensation with low
overshooting. 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:
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 activa-
tion 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.
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 over-
shooting. 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.
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.

Service and Maintenance
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.

8. Replace the cover and screw it tight.
9. Re-connect the pipes and supply pneumatic energy.
!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. When ordering replacement equipment,
please specify the serial number of the original equipment. You will find
the serial number on the name plate.

Scope of Delivery
The positioner and its options modules are delivered as separate units
and in different versions. Positioners and options modules for operation
in hazardous areas and non-hazardous areas are available. These ver-
sions are identified respectively by a special rating plate.
!WARNING
In the combination of components it must be ensured that only positio-
ners 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 poten-
tially explosive (zone 1 and 2). The instrument categories (2 and 3) of
the instrument itself and those of its options must be observed.
