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.
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.
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.
7 1 Markings used 1.1 Symbols on the transducer Symbol: Meaning: Read and note the data in this manual Label example Label example with FCC ID and IC number. Location of the label on the stator device. 1.2 The markings used in this document Important instructions for your safety are specifically identified. It is essential to follow these instructions in order to prevent accidents and damage to property.
8 Symbol Meaning This marking draws your attention to information about the product or about handling the product. Emphasis 2 Italics are used to emphasize and highlight texts. 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.
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.
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.
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.

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.

The upper antenna segment can be separated from the stator, for example, for maintenance or to facilitate stator mounting.
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.
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.
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).
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.
19 5.3 Connector pin assignment The stator housing has two 7 pin connectors, an 8 pin connector and a 16 pin connector. The supply voltage connections and shunt signal connections of connectors 1 and 3 are each electrically interconnected, but are protected against compensating currents by diodes. There is also an automatically resetting fuse (multifuse) to protect the supply connections against overload by the stator. Assignment for connector 1: Supply voltage and frequency output signal.
20 Assignment for connector 2: Speed output signal (optional).
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.
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.
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.
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. 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.
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.
26 9 Maintenance The T40HS torque flanges are maintenance-free. 10 Waste disposal and environmental protection All electrical and electronic products must be disposed of as hazardous waste. The correct disposal of old equipment prevents ecological damage and health hazards. Symbol: Meaning: Statutory waste disposal mark The electrical and electronic devices that bear this symbol are subject to the European waste electrical and electronic equipment directive 2002/96/EC.
