HBM: Business Document Model: TJ1-S9 FCC ID: 2ADAT-TJ1S9 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 electron- ics for transmitting the bridge excitation voltage and the measurement signal are located centrally in the flange. The transmitter coils for contactless trans- mission of excitation voltage and measurement signal are located on the measuring body's outer circumference. The signals are sent and received by a separable stator antenna. The antenna has to be mounted close to the rotor antenna. The connection cable connects the stator antenna with the evaluation unit which contains the electronics for voltage adaptation and the signal conditioning. Connector plugs for the torque signal and the voltage supply are located on the evaluation unit. The stator antenna should be mounted tangential with some gap to the rotor antenna (see chapter 5). Fig 4.1: Mechanical construction in principle
4 HBM: Business Document Fig 4.2: Mechanical construction of stator with mounted shielding 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 NOTE 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, even 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 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.  If alternating loads are expected, use thread locker (medium strength, e.g. LOCTITE No. 242) to fix the screws into the threaded holes to exclude loss of tightening stress due to screw slackening.  Comply with the mounting dimensions to enable correct operation. 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.
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 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. 5.2 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 out- put and zero signals of the transducer (see “Specifications" section). 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 load, the output signal is from 10 kHz to 15 kHz corresponding zero to nominal torque load.
7 HBM: Business Document 5.4 Installation Please mount the rotor & stator simultaneous to its final position, so that you don’t need to separate the stator winding. The stator antenna should only be separated in case of an emergency. For dismounting instructions please contact the responsible HBM sales engineer. 5.5 Preparing for the rotor mounting (exemplary) CAUTION The rotor is very heavy (approx. 370kg)! 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
8 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)
9 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 1. Prior to installation, clean the plane faces 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. When cleaning, make sure that you do not damage the transmitter winding. Important If alternating loads are expected, use thread locker (medium strength, e.g. LOCTITE No. 242) to glue the screws into the counter thread to exclude loss of tightening stress due to screw slackening. 3. Fasten all screws with the specified torque. 4. Now remove the ring bolts and mounting ring(s). Important Keep them in a safe place for future dismounting.
10 HBM: Business Document 5.7 Installing the telemetry system The telemetry system consists of the following component parts:  Rotor antenna  Stator antenna  Stator  Evaluation unit  Connection cable Fig 5.4: Component parts Important  Do not bend the connection cable  Do not shorten or stretch the connection cable  Do not guide the cable close to energy- or power circuit lines  The stator antenna has to be mounted directly above the rotor antenna  The stator antenna has to be mounted in the middle of the adjustment range of the rotor antenna
11 HBM: Business Document  The stator antenna must not touch the rotor antenna CAUTION  At all mounting- dismounting or repair operations, switch of the power supply of the system.  Connectors must not be under electric tension while it will be connected or disconnected 5.7.1 Measuring setup Fig 5.5: Block diagram
