4 Intended use The T40HS torque flange is used exclusively for torque, angle of rotation and power measurement tasks within the load limits stipulated in the specifications. Any other use is not the designated use. Stator operation is only permitted when the rotor is installed. The T40HS 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 T40HS 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 careful operation. Loading capacity limits The data in the technical data sheets must be complied with when using the T40HS torque flange. In particular, the respective maximum loads specified must never be exceeded. The following limits set out in the specifications must not be exceeded, e.g.: • Limit torque • Longitudinal limit force, lateral limit force or bending limit moment • Torque vibration bandwidth • Breaking torque • Temperature limits • Limits of electrical loading capacity Use as a machine element The T40HS 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.
5 Accident prevention According to the prevailing accident prevention regulations, once the transducers 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. • Covers 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 T40HS torque flange are installed outside peoples' movement and working range. The only permitted exceptions to the above requirements are if the T40HS torque flange is already fully protected by the design of the machine or by existing safety precautions. Additional safety precautions The T40HS torque flange cannot (as a passive transducer) implement any (safety-relevant) cutoffs. This requires additional components and constructive measures 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 engineering considerations in such a way as to minimize residual dangers. Pertinent national and local regulations must be complied with. General dangers of failing to follow the safety instructions The T40HS torque flange is state of the art and reliable. Transducers 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 T40HS 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 applicable safety regulations (BG 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 property or injury to persons in the vicinity of the transducer. If the T40HS 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 affected (due to the torques acting on or being monitored by the T40HS 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.
6 Selling on If the T40HS torque flange is sold on, these mounting instructions must be included with the T40HS 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.

8 Symbol Meaning This marking draws your attention to information about the product or about handling the product. Emphasis Italics are used to emphasize and highlight texts. 2 Application The T40HS torque flange measures static and dynamic torques on stationary and rotating shafts. Test beds can be extremely compact because of the short construction of the transducer. This offers a very wide range of applications. The T40HS torque flange is reliably protected against electromagnetic interference. It has been constructed according to the relevant European standards (e.g. EMC behavior) and/or complies with US and Canadian standards. The product carries the FCC label.
9 3 Structure and mode of operation The T40HS 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 includes the electronic system for voltage adaptation and signal conditioning. Connectors for the torque and speed signals, the voltage supply and the digital output are located on the stator. The antenna segments (ring) should be mounted more or less concentrically around the rotor (see Chapter 4). Antenna segments Rotor Connector plug Connector plug Identification plate Stator housing Fig. 3.1: Possible mechanical construction without speed measuring system
10 4 Mechanical installation 4.1 Important precautions during installation NOTE A T40HS 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, even while it is being mounted. • Handle the transducer with care. • Check the effect of bending moments, critical speeds and natural torsional oscillations, to prevent the transducer being overloaded by increases in resonance. • Make sure that the transducer cannot be overloaded. WARNING 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 screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws into the counter thread to exclude prestressing loss due to screw slackening, if alternating loads are to be expected. • Comply with the mounting dimensions to enable correct operation. An appropriate shaft flange enables the T40HS 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 T40HS torque flange's high torsional stiffness, dynamic shaft train changes are kept to a minimum.
11 Important Even if the unit is installed correctly, the zero point adjustment made at the factory can shift by up to approx. 2% of the sensitivity. 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. 4.2 Conditions on site The 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 "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. 4.3 Mounting position The T40HS torque flange can be mounted in any position. With clockwise torque, the output frequency is, depending on the option, 60 - 90 kHz, 10 - 15 kHz or 240 - 360 kHz). With HBM amplifiers or with the voltage output option, a positive output signal (0 V -+10 V) is present. 4.4 Installation options For T40HS torque flange mounting 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 4.4.1). 4.

13 4.5 Mounting the rotor Tip Usually the rotor identification plate is no longer visible after installation. This is why we include with the rotor additional stickers with the important ratings, 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. 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 or the speed measuring system. 2. For the bolted rotor connection (see Fig. 4.9), use DIN EN ISO 4762 hexagon socket screws of the property class stated in Table 4.1, in a suitable length (dependent on the connection geometry, see Table 4.1 on Page 14). We recommend DIN EN ISO 4762 fillister head screws, blackened, smooth-headed, permitted size and shape variance in accordance with DIN ISO 4759, Part 1, product class A. Important Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws into the counter thread to exclude pre-stressing loss due to screw slackening, if alternating loads are to be expected. 3. Fasten all screws with the specified torque (Table 4.1 on page 14). 4. There are tapped holes on the rotor for further mounting. Also use screws of property class 10.9 or 12.9, and fasten with the torque specified in Table 4.1. Important Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the screws into the counter thread to exclude pre-stressing loss due to screw slackening, if alternating loads are to be expected.

The upper antenna segment can be separated from the stator, for example, for maintenance or to facilitate stator mounting. If your application does not require the stator to be dismantled, proceed as described in points 2., 5., and 6. Antenna segment bolts with washers (M5) Fan-type lock washers Hole for fixing the antenna segment, diameter 4.2 mm top Antenna segments bottom Stator housing Fig. 4.10: Bolted connection of the antenna segments on the stator
15 1. Undo and remove the bolted connections (M5) on the upper antenna segment. There are fan type lock washers between the antenna segments: Make sure that they do not get lost. 2. Use an appropriate base plate 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. 3. Then align the antenna to the rotor in such a way that the antenna encloses the rotor more or less coaxially and the antenna wire in the axial direction shows the position and the center of the transmitter winding on the rotor. Please comply with the permissible alignment tolerances stated in the specifications. 4. Now use two hexagon socket screws to mount the upper antenna segment removed in Point 1 on the lower antenna segment. Make sure that the two fan type lock washers are inserted between the antenna segments (these ensure that there is a defined contact resistance)! Important 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. Now fully tighten the bolted stator housing connection. 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 (depends on the measuring range) • The design of the machine base
16 Important To prevent this axial oscillation, the antenna ring requires additional support by the customer. There is a hole on the upper antenna segment (with M5 internal thread), which can be used to incorporate a clamping device (see Fig. 4.13). The cable plug also requires support in this case, a construction example is shown in Fig. 4.14. Fig. 4.13: Construction example for supporting the antenna ring Fig. 4.14: Construction example for connector terminals (for two connectors)
17 5 Electrical connection 5.1 General instructions • With cable extensions, make sure that there is a proper connection with minimum contact resistance and good insulation. • All plug connections or swivel nuts must be fully tightened. Important Transducer connection cables from HBM with attached connectors are identified in accordance with their intended purpose (Md or n). When cables are shortened, inserted into cable ducts or installed in control cabinets, this identification can get lost or become concealed. Mark the cables before laying them in this case. 5.2 EMC protection Important The product offered here is a special module for stationary plants or a transducer for installation by system integrators and plant engineers and is not intended for general sale. This product does not need an EC Declaration of Conformity or CE marking in compliance with EMVG1 §12 Paragraph 2 and directive 2004/1008/EC Article 13 Paragraph 1. The product is exclusively manufactured and intended for further processing by companies or persons with expertise in the sector of electromagnetic compatibility (EMC). Relevant EMC protection aims are met with regards to the offered product when the following instructions for installation are observed and implemented. Special electronic coding methods are used to protect the purely digital signal transmission between the transmitter head and the rotor from electromagnetic interference.
18 The cable shield is connected with the transducer housing. This encloses the measurement system (without the rotor) in a Faraday cage when the shield is laid flat at both ends of the cable. With other connection techniques, an EMC-proof shield should be applied in the wire area and this shielding should also be connected extensively (see also HBM Greenline Information, brochure i1577). Electrical and magnetic fields often induce interference voltages in the measuring circuit. Therefore: • Use shielded, low-capacitance measurement cables only (HBM cables fulfill both conditions). • 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 stator housing 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.

21 5.4 Supply voltage The transducer is operated with a separated extra-low voltage (nominal (rated) supply voltage 18 - 30 VDC). You can supply one or more T40HS torque flanges simultaneously within a test bench. 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 standalone operation of the T40FM without HBM system solutions. The supply voltage is electrically isolated from signal outputs and shunt signal inputs. Connect a separated extra-low voltage of 18 V - 30 V to pin 3 (+) and pin 2 (-) of plug 1 or 3. We recommend that you use HBM cable KAB 8/00-2/2/2 and appropriate sockets (see Accessories). The cable can be up to 50 m long for voltages 24 V, otherwise it can be up to 20 m long. If the permissible cable length is exceeded, you can supply the voltage in parallel over two connection cables (connectors 1 and 3). This enables you to double the permissible length. Alternatively, install a power supply on site. Important 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. 1) Distribution system for electrical energy with greater physical dilatation (over several test benches, for example) that may possibly also supply consumers with high nominal (rated) currents.
22 6 Shunt signal Triggering the shunt signal Applying a separated extra-low voltage of 5 - 30 V to pins 6 (+) and 7 (-) at connector 1 or 3 triggers the shunt signal. The nominal (rated) voltage for triggering the shunt signal is 5 V (triggering at U > 2.5 V), but when voltages are less than 0.7 V, the transducer is in measuring mode. The maximum permissible voltage is 30 V, current consumption at nominal (rated) voltage is approx. 2 mA and at maximum voltage, approx. 18 mA. The trigger voltage for the shunt signal is electrically isolated from the supply voltage and the measurement voltage. The transducer should not be under load when the shunt signal is being measured, since the shunt signal is mixed additively. The T40HS torque flange delivers an electrical shunt signal that in measuring chains with HBM components, can be activated from the amplifier. 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, adjust the amplifier output signal to the shunt signal supplied by the connected transducer to adapt the amplifier to the transducer. Tip The shunt signal can be triggered by the amplifier or via the operating software in HBM system solutions.
23 7 Functionality testing You can check the functionality of the rotor and the stator from the LEDs on the stator. LED A rotor status LED B stator status Fig. 7.1: LEDs on the stator housing 7.1 Rotor status, LED A (upper LED) Color Meaning Green (pulsating) Internal rotor voltage values OK Flashing orange Rotor and stator mismatched (an increasing flashing frequency indicates the degree of misalignment) => Correct the rotor/stator alignment. Pulsating orange Rotor status cannot be defined => Correct the rotor/stator alignment. If the LED still pulsates orange, it is possible that there is a hardware defect. The measurement signals reflect the level of the defect status. Red (pulsating) Rotor voltage values NOK. => Correct the rotor/stator alignment. If the LED still pulsates red, it is possible that there is a hardware defect. The measurement signals reflect the level of the defect status. Pulsating means that the LED goes dark for about 20 ms every second (sign of life); making it possible to detect that the transducer is functioning.
24 7.2 Stator status, LED B (lower LED) Color Meaning Green (permanently lit) Measurement signal transmission and internal stator voltages OK Green, intermittently orange. For many synchronization errors: Constant orange Orange until end of defective transmission if ≥5 incorrect measured values in sequence are transmitted. The measurement signals reflect the level of the defect status for the duration of the transmission defect + approx. another 3.3 ms. Orange (permanently lit) Permanently disrupted transmission, the measurement signals reflect the level of the defect status. (fout = 0 Hz, Uout = defect level). => Correct the rotor/stator alignment. Red (permanently lit) Internal stator defect, the measurement signals reflect the level of the defect status (fout = 0 Hz, Uout = defect level).
25 8 Loading capacity Nominal torque can be exceeded statically up to the limit torque. If the nominal torque is exceeded, additional irregular loading is not permissible. This includes longitudinal forces, lateral forces and bending moments. Limit values can be found in the chapter "Specifications" (Chapter 13, Page 34). Measuring dynamic torque The T40HS torque flange can be used to measure static and dynamic torques. The following rule applies to the measurement of dynamic torque: • The transducer calibration performed for static measurements is also valid for dynamic torque measurements. • The natural frequency f0 of the mechanical measurement setup depends on the moments of inertia J1 and J2 of the connected rotating masses, and the torsional stiffness of the transducer. Use the equation below to approximately determine the natural frequency f0 of the mechanical measuring arrangement: • The permissible mechanical vibration bandwidth (peak-peak) can also be found in the specifications. Nominal (rated) torque Mnom in % + Mnom Oscillation width Oscillation width 0 time t 200% oscillation width - Mnom Oscillation width Fig. 8.1: Permissible dynamic loading Natural frequency in Hz Mass moment of inertia in Torsional stiffness in N m/rad

Otherwise the limit values must be reduced. If for instance 30 % of the bending limit moment and also 30 % of the lateral limit force are present, only 40 % of the axial limit force are permitted, provided that the nominal (rated) torque is not exceeded. With the permitted bending moments, axial, and lateral limit forces, measuring errors of about 0.3 % of the nominal (rated) torque can occur. 8) With static loading 9) Static and dynamic 10) The nominal rated) torque must be exceeded Notes: • Extremely high dynamic vibration, velocity, accelerations and running at shaft resonance have to be avoided, otherwise measuring can be wrong or transducer can be damaged (rotational acceleration max. 30000rpm/s)!
