compliance with FCC regulations.
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.
The FCC identifier or the unique identifier, as appropriate, must be displayed on
the device.

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.

Appropriate use
The torque transducer 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 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 careful 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 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.
• 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 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 torque flange corresponds to the state of the art and is failsafe. 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 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 property 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 requirements:
- 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. You
are also authorized to activate, ground and label circuits and equipment in
accordance with safety engineering standards.

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 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).

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.
