HBM: Business Document Model: TCA-S5 FCC ID: 2ADAT-TCAS5 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Fig. 1.2 Example of the label Appropriate use The torque transducer is used exclusively for torque, angle of rotation and power measurement tasks within the load limits stipulated in the specifica- tions. Any other use is not the designated use. Stator operation is only permitted when the rotor and stator antenna are coupled. The torque flange may only be installed by qualified personnel in compliance with the specifications and with the safety requirements and regulations of these mounting instructions. It is also essential to observe the applicable legal and safety regulations for the application concerned. The same applies to the use of accessories. The torque flange is not intended for use as a safety component. Please also refer to the section: “Additional safety precautions". Proper and safe operation requires proper transportation, correct storage, siting and mounting, and care- ful operation. Loading capacity limits The data in the technical data sheets must be complied with when using the torque flange. In particular, the respective maximum loads specified must never be exceeded. The values stated in the specifications‐must not be exceeded, for example, for  limit torque,  longitudinal limit force, lateral limit force or limit bending moment,  torque oscillation width,  breaking torque,  temperature limits,  the limits of the electrical loading capacity.
HBM: Business Document Use as a machine element The torque flange can be used as a machine element. When used in this manner, it must be noted that, to favor greater sensitivity, the transducer is not designed with the safety factors usual in mechanical engineering. Please refer here to the section “Loading capacity limits", and to the specifications. Accident prevention According to the prevailing accident prevention regulations, once the trans- ducers have been mounted, a covering agent or cladding has to be fitted as follows:  The covering agent or cladding must not be free to rotate.  The covering agent or cladding should prevent squeezing or shearing and provide protection against parts that might come loose.  Covering agents and cladding must be positioned at a suitable distance or be so arranged that there is no access to any moving parts within.  Covering agents and cladding must still be attached even if the moving parts of the torque flange are installed outside people's movement and working range. The only permitted exceptions to the above requirements are if the torque flange is already fully protected by the design of the machine or by existing safety precautions. Additional safety precautions The torque flange cannot (as a passive transducer) implement any (safety‐rel evant) cutoffs. This requires additional components and constructive meas- ures for which the installer and operator of the plant is responsible. The layout of the electronics conditioning the measurement signal should be such that measurement signal failure does not cause damage. The scope of supply and performance of the transducer covers only a small area of torque measurement technology. In addition, equipment planners, installers and operators should plan, implement and respond to safety engin- eering considerations in such a way as to minimize residual dangers. Pertin- ent national and local regulations must be complied with. General dangers of failing to follow the safety instructions The torque flange corresponds to the state of the art and is failsafe. Trans- ducers can give rise to residual dangers if they are incorrectly operated or inappropriately mounted, installed and operated by untrained personnel. Every person involved with siting, starting‐up, operating or repairing a torque flange must have read and understood the mounting instructions and in particular the technical safety instructions. The transducers can be damaged or destroyed by non-designated use of the transducer or by non-compliance with the mounting and operating instructions, these safety instructions or any other
HBM: Business Document applicable safety regulations (safety and accident prevention regulations), when using the transducers. Transducers can break, particularly in the case of overloading. The breakage of a transducer can also cause damage to prop- erty or injury to persons in the vicinity of the transducer. If the torque flange is not used according to the designated use, or if the safety instructions or specifications in the mounting and operating instructions are ignored, it is also possible that the transducer may fail or malfunction, with the result that persons or property may be adversely affected (due to the torques acting on or being monitored by the torque flange). Conversions and modifications The transducer must not be modified from the design or safety engineering point of view except with our express agreement. Any modification shall exclude all liability on our part for any damage resulting therefrom. Selling on If the torque flange is sold on, these mounting instructions must be included with the torque flange. Qualified personnel Qualified personnel means persons entrusted with siting, mounting, starting up and operating the product, who possess the appropriate qualifications for their function. This includes people who meet at least one of the three following require- ments: - Knowledge of the safety concepts of automation technology is a requirement and as project personnel, you must be familiar with these concepts. - As automation plant operating personnel, you have been instructed how to handle the machinery. You are familiar with the operation of the equipment and technologies described in this documentation. - As commissioning engineers or service engineers, you have successfully completed the training to qualify you to repair the automation systems.

3 HBM: Business Document 4 Structure and mode of operation The torque flange consists of two separate parts: the rotor and the stator. The rotor comprises the measuring body and the signal transmission elements. Strain gauges (SGs) are installed on the measuring body. The rotor electronics for transmitting the bridge excitation voltage and the measurement signal are located centrally in the flange. The transmitter coils for contactless transmission of excitation voltage and measurement signal are located on the measuring body's outer circumference. The signals are sent and received by a separable antenna ring. The antenna ring is mounted on a housing that contains the electronics for the automatic self-tuning function of the antenna. The connection cable connects the stator housing with the evaluation unit which contains the electronics for voltage adaptation and the signal conditioning. Connectors and screw terminals for the torque signal and the voltage supply are located on the evaluation unit. The stator antenna ring should be mounted more or less concentrically with some gap to the rotor antenna (see Chapter 5). Fig. 4.1: Transducer with stator antenna and evaluation unit
4 HBM: Business Document Fig. 4.2: EMI suppressor Important The use of the shielding plates is important to ensure compliance with FCC regulations. If the shielding plates has to be removed for any purpose (e.g. installation or maintenance), they must be replaced in the original position before the product is used.
5 HBM: Business Document 5 Mechanical installation 5.1 Important precautions during installation A torque flange is a precision measurement element and therefore needs careful handling. Dropping or knocking the transducer may cause permanent damage. Make sure that the transducer cannot be overloaded, including while it is being mounted.  Handle the transducer with care.  Check the effect of bending moments, critical rotational speeds and natural torsional oscillations, to prevent the transducer being overloaded by resonance sharpness  Make sure that the transducer cannot be overloaded. There is a danger of the transducer breaking if it is overloaded. This can cause danger for the operating personnel of the system in which the transducer is installed. Implement appropriate safety measures to avoid overloads and to protect against resulting dangers.  Use a Use a thread locker (medium strength, e.g. LOCTITE) to glue the screws into the counter thread to exclude prestressing loss due to screw slackening, in the event of alternating loads.  Comply with the mounting dimensions to enable correct operation. An appropriate shaft flange enables the special torque flange to be mounted directly. It is also possible to mount a joint shaft or relevant compensating element directly on the rotor (using an intermediate flange when required). Under no circumstances should the permissible limits specified for bending moments, lateral and longitudinal forces be exceeded. Due to the torque flange's high torsional stiffness, dynamic shaft train changes are kept to a minimum. NoteWARNING
6 HBM: Business Document Important Even if the unit is installed correctly, the zero point adjustment made at the factory can shift by up to approx. 0.5% of the characteristic value. If this value is exceeded, we advise you to check the mounting conditions. If the residual zero offset when the unit is removed is greater than 1% of the sensitivity, please send the transducer back to the Darmstadt factory for testing. 5.2 Conditions on site The special torque flange must be protected against coarse dirt particles, dust, oil, solvents and humidity. There is wide ranging compensation for the effects of temperature on the output and zero signals of the transducer (see Chapter 13, "Specifications"). If there are no static temperature ratios, for example, because of the temperature differences between the measuring body and the flange, the values given in the specifications can be exceeded. In this case, ensure static temperature ratios by cooling or heating, depending on the application. As an alternative, check if thermal decoupling is possible, e.g. by means of heat radiating elements such as multiple disc couplings. 5.3 Installation orientation The torque flange can be installed with any orientation. With clockwise torque, when using the voltage output mode a positive output signal (0 V…+10 V) or when using the frequency output mode an output frequency of 10 kHz … 15 kHz is present on the output (corresponding zero to nominal torque load). 5.4 Installation options There are basically two options for mounting the special torque flange: with or without dismantling the antenna ring. We recommend mounting as described in Chapter 5.4.1. If mounting in accordance with Chapter 5.4.1 is not possible (e.g. in the case of subsequent stator replacement), you will have to dismantle the antenna ring. It is essential in this case to comply with the notes on assembling the antenna segments (see Chapter 5.4.2).

9 HBM: Business Document 5.5 Preparing for the rotor mounting (exemplary) CAUTION The rotor is heavy Use a crane or other suitable lifting equipment to lift it out of its packaging and install it. Use flexible eye bolts as transport and mounting aids. Hook the lifting equipment to these eye bolts as this ensures that the rotor is lifted horizontally out of the packaging (see Fig 4.1). Transport and mounting eye bolts Fig 5.1: Transport and mounting eye bolts on the rotor
10 HBM: Business Document 1. Lift the rotor out of the packaging, rotate horizontally by 180°, so that the bigger flange is pointing upwards (see exemplary Fig 5.1). Flange B Fig 5.2: Rotating the rotor 2. Place the rotor carefully onto a clean and stable table. 3. If the rotor is to be installed horizontally as shown in Fig 5.3, remove one mounting eye bolt. Both mounting eye bolts can initially remain in the flange for vertical installation. Fig 5.3: Rotor installation (horizontal)
11 HBM: Business Document 4. Clean the plane surfaces of the transducer flange and the counter flange. For safe torque transfer, the faces must be clean and free from grease. Use a piece of cloth or paper soaked in solvent. Make sure that no solvent drips into the inside of the transducer and that the transmitter coils are not damaged during cleaning. 5. Fasten the lifting equipment to the mounting eye bolt(s). 6. Carefully lift up the rotor and move it to the mounting position (see Fig 5.1). 5.6 Mounting the rotor Usually the rotor identification plate is no longer visible after installation. This is why we include with the rotor additional stickers with the important characteristics, which you can attach to the stator or any other relevant test-bench components. You can then refer to them whenever there is anything you wish to know, such as the shunt signal. To explicitly assign the data, the identification number and the size are engraved on the rotor flange, where they can be seen from outside. Make sure during installation that you do not damage the measuring zone marked in Fig. 5.4 by using it to support tools or knocking tools against it when tightening screws, for example. This can damage the transducer and produce measurement errors, or even destroy the transducer. 1. Prior to installation, clean the plane surfaces of the transducer flange and the counter flange. For safe torque transfer, the surfaces must be clean and free from grease. Use a piece of cloth or paper soaked in solvent. When cleaning, make sure that you do not damage the transmitter winding. TipNote
12 HBM: Business Document Fig. 5.4: Bolted rotor connection 2. For the connection of flange A (see Fig. 5.4), use DIN EN ISO 4762 property class 10.9 hexagon socket screws of a suitable length (dependent on the connection geometry, see Tab. 5.1). We recommend fillister head screws DIN EN ISO 4762, blackened, smooth headed, permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product class A. 3. Fasten all screws with the specified torque (Table 5.1). 4. Now remove the eye bolt(s) used for transportation and mounting. Keep them in a safe place for future dismounting. 5. There are relevant tapped holes on flange B for continuing the shaft train mounting. Again use screws of property class 10.9 and tighten them with the pre scribed torque, as specified in Tab. 5.1. Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screws into the counter thread to exclude prestressing loss due to screw slackening, in the event of alternating loads. ImportantImportant
13 HBM: Business Document Comply with the maximum screw-in depth as per Tab. 5.1. Otherwise significant measurement errors may result from torque shunt, or the transducer may be damaged. Dry screw connections can result in different and higher friction factors (see VDI 2230, for example). This means a change to the required tightening moments. The required tightening moments can also change if you use screws with a surface or property class other than that specified in Tab. 5.1, as this affects the friction factor 5. There are relevant tapped holes on flange B for continuing the shaft train mounting. Again use screws of property class 10.9 and tighten them with the pre scribed torque, as specified in Tab. 5.1. NoteImportant
14 HBM: Business Document 5.7 Installing the stator On delivery, the stator has already been installed and is ready for operation. If necessary, the antenna segments can be divided from the antenna segment clamp for maintenance or to facilitate stator mounting. We recommend to use the stator ring as it is and to only open if absolutely necessary. When the flexible antenna segments are bent, they easily deviate from circularity. Prevent the antenna segments from a large deformation while bending. While opening the stator ring, bend the antenna segments only as wide as necessary to slip them over a thin part of the shaft nearby. Fig. 5.5: Bolted connection of the antenna segments on the stator 1. Undo and remove the bolted connections (M4) on the Antenna segment clamp. There are fan type lock washers (or toothed washers) between the antenna segments: Make sure that they do not get lost. ImportantAntenna segmentscrews M4Toothed washerbetween the segmentsM5 mounting slots forfor fixing the stator ringAntenna segmentscrews M5Toothed washersStator housingAntenna segmentsAntenna segment clampand fixation point
15 HBM: Business Document 2. Careful bend the antenna segments to the necessary amount of gap and slip the antenna ring over the thinnest part of the shaft nearby. 3. Use an appropriate mounting base to install the stator housing in the shaft train so that there is sufficient opportunity for horizontal and vertical adjustments. Do not fully tighten the bolts yet. 4. Now use two hexagon socket screws to mount the antenna segment clamp removed in Point 1. Make sure that the fan type lock washer is inserted between the antenna segments (these ensure that there is a defined contact resistance)! To make sure that they function perfectly, the fan-type lock washers (A5.3-FST DIN 6798 ZN/galvanized) must be replaced after the bolted antenna connection has been loosened three times. 5. Now tighten all antenna-segment bolted connections with a tightening torque of 5 Nm. 6. Then align the antenna to the rotor in such a way that the antenna encloses the rotor more or less coaxially and the antenna ring in the axial direction shows the position and the center of the transmitter winding on the rotor (on flange B). Fig. 5.6: Bolted connection of the antenna segments on the stator 6. Now fully tighten the bolted stator housing connection. Important
16 HBM: Business Document Prevention of stator axial oscillation Depending on the operating conditions, the stator may be excited to vibrate. This effect is dependent on:  The rotational speed,  The antenna diameter,  The design of the machine base. To prevent this axial oscillation, the antenna ring requires additional support by the customer. There are two mounting slots on the upper antenna segment clamp (with an inner diameter of 5.5mm), which can be used to incorporate a clamping device .The cable plug also requires support in this case, a construction example is shown in Fig. 5.7 Fig. 5.7: Construction example for connector cables (here for two plugs, needs adjustment to MPZ1604008 to only one plug) Important
17 HBM: Business Document 6 General information  With extension cables, make sure that there is a proper connection with minimum contact resistance and good insulation.  All cable connectors or swivel nuts must be fully tightened. 6.2 EMC protection The product offered is a special assembly for stationary systems that is not available on the general market or a transducer for installation by system integrators and plant manufacturers. According to EMVG1 §12 paragraph 2 and Directive 2004/1008/EC article 13 paragraph 1 this product does not require an EC declaration of conformity nor the CE marking. This product is intended exclusively for subsequent processing by companies or persons that are experts in the field of electromagnetic compatibility (EMC). Relevant EMC protection requirements relating to the product offered are met when the following Installation notes are observed and implemented. Installation notes Please note the following points during installation and use:  It is essential to observe the specifications and notes provided in the operating manual and the data sheet  Connecting cables, in particular the measuring and control cables, need to be shielded  Make sure that the transducer and shielding are connected extensively to ground.  Ensure an interference-free environment, avoid radiation interference  Devices connected to this product need to comply with protection requirements per EMVG (Gesetz über die elektromagnetische Verträglichkeit von Geräten / law on electromagnetic compatibility of instruments). You have to install the shield of the connection cable at the shielded housing of the electronics, to achieve the EMC-protection of the measuring chain. Make sure that the transducer and shielding are connected extensively to ground. Important
18 HBM: Business Document Electrical and magnetic fields often induce interference voltages in the measuring circuit. Therefore:  Use shielded, low-capacitance measurement cables only  Only use plugs that meet EMC guidelines.  Do not route the measurement cables parallel to power lines and control circuits. If this is not possible, protect the measurement cable with e.g. steel conduit.  Avoid stray fields from transformers, motors and contact switches.  Do not ground the transducer, amplifier and indicator more than once.  Connect all devices in the measurement chain to the same grounded conductor.  In the case of interference due to potential differences (compensating currents), supply voltage zero and housing ground must be disconnected on the amplifier and a potential equalization line established between the evaluation unit and the amplifier housing (copper conductor, minimum 10 mm² wire cross-section).  Should differences in potential between the machine rotor and stator, because of unchecked leakage, for example, cause interference, this can usually be overcome by connecting the rotor definitively to ground, e.g. with a wire loop. The stator must be connected to the same (ground) potential.

22 HBM: Business Document 6.4 Supply voltage The transducer must be operated with a separated extra low voltage (supply voltage 9 … 36 VDC). You can supply one or more torque flanges within a test bench at the same time. Should the device be operated on a DC voltage network1), additional precautions must be taken to discharge excess voltages. The information in this Chapter relates to the self-contained operation of the special torque transducer without HBM system solutions. The supply voltage is electrically isolated from signal out puts and shunt signal inputs. Connect a separated extra low voltage of 9 V … 36 V DC to bracket 7 (+) and bracket 8 (-) of the evaluation unit. The cable can be up to 50m long for voltages ≥24V, otherwise it can be up to 20m long. 1) Distribution system for electrical energy with greater physical expansion (over several test benches, for example) that may possibly also supply consumers with high nominal (rated) currents At the instant of power-up, a current of up to 4 A may flow, which could switch off power packs with electronic current limiters. Important
23 HBM: Business Document 6.5 Use of EMI suppressor To suppress high frequencies a EMI suppressor on the cable between rotor and stator has to be used. Use at least 1 loops of the cable. Fastening must be done in an area not subject to mechanical loads (i.e. no unwanted vibrations, etc.) using cable ties fit for the specific application. Fig 6.1: Installation example EMI suppressor Information Consider longer cable of approximately 40cm due to the installation of the EMI suppressor. The max. distance of EMI suppressor to connector is 500mm. If the EMI suppressor has to be removed for any purpose (e.g. for maintenance), it must be replaced on the cable. Use only EMI suppressor of the correct type. Type: Vitroperm R Model No.: T60006-22063W517 Size: external diameter x internal diameter x height = 63 x 50 x 25 Important The use of the EMI suppressor on the power cable is mandatory to ensure compliance with FCC regulations.
24 HBM: Business Document
25 HBM: Business Document 7 Shunt signal The special torque flange delivers an electrical shunt signal that can be activated from the evaluation unit for measuring chains with HBM components. The transducer generates a shunt signal of about 50% of the nominal (rated) torque; the precise value is specified on the type plate. After activation of push button no. 15 (see Fig. 6.1), the shunt signal is activated for a time span of 5s. Adjust the amplifier output signal to the shunt signal supplied by the connected transducer to adapt the amplifier to the transducer. The transducer should not be under load when the shunt signal is being measured, as the shunt signal is mixed additively. Triggering the shunt signal Push button no. 15 (see Fig. 6.1) on the evaluation unit to activate the shunt signal for a time span of 5s. Information

If this condition is not met, the limit values must be reduced. If 30% of the limit bending moment and lateral limit force occur at the same time, only 40% of the longitudinal limit force is permissible and the nominal (rated) torque must not be exceeded. The effects of permissible bending moments, longitudinal and lateral forces on the measurement result are ≤±1% of the nominal (rated) torque. The load limits only apply for the nominal (rated) temperature range. At temperatures <10°C, the load limits must be reduced by approx. 30% (strength reduction). 3) The data refer to static loading of the measuring body; note the bolted connection! 4) The nominal (rated) torque must not be exceeded.
