Safety instructions
Designated use
The T10FS torque flange is used exclusively for torque and rotation speed
measurement tasks, and directly associated control and regulatory tasks. Use
for any additional purpose shall be deemed to be not as intended.
In the interests of safety, the transducer should only be operated as described
in the Operating Manual. It is also essential to comply with the legal and
safety requirements for the application concerned during use. The same
applies to the use of accessories.
The transducer is not a safety element within the meaning of its designated
use. Proper and safe operation of this transducer requires proper
transportation, correct storage, assembly and mounting, and careful
operation.
General dangers of failing to follow the safety instructions
The transducer corresponds to the state of the art and is failsafe. The
transducer can give rise to remaining dangers if it is inappropriately installed
and operated by untrained personnel.
Everyone involved with mounting, starting up, maintaining, or repairing the
transducer must have read and understood the Operating Manual and in
particular the technical safety instructions.
Residual dangers
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 the safety
engineering considerations of torque measurement technology in such a way
as to minimize remaining dangers. On‐site regulations must be complied with
at all times. Reference must be made to remaining dangers connected with
torque measurement technology.

The following symbols are used in this Operating Manual to point out
remaining dangers:
Symbol: DANGER
Meaning: Maximum danger level
Warns of an imminently dangerous situation in which failure to comply with
safety requirements will result in death or serious physical injury.
Symbol: WARNING
Meaning: Possibly dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious physical injury.
Symbol: ATTENTION
Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could result in damage to property or some form of
physical injury.
Symbols for application and disposal instructions, as well as useful
information:
Symbol: NOTE
Means that important information about the product or its handling is being
provided.
Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product
complies with the requirements of the relevant EC directives (the Declaration
of Conformity can be found at http://www.hbm.com/HBMdoc).

Symbol:
Meaning: Statutory waste disposal mark
In accordance with national and local environmental protection and material
recovery and recycling regulations, old devices that can no longer be used
must be disposed of separately and not with normal household garbage.
If you need more information about waste disposal, please contact your local
authorities or the dealer from whom you purchased the product.
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.
Qualified personnel
The transducer must only be installed and used by qualified personnel, strictly
in accordance with the specifications and with safety requirements and
regulations. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Qualified personnel means persons entrusted with siting, mounting, starting
up and operating the product who possess the appropriate qualifications for
their function.

Accident prevention
According to the prevailing accident prevention regulations, once the torque
flange has been mounted, a covering agent or cladding has to be fitted as
follows:
The cover or cladding must not be free to rotate.
The cover or cladding should avoid squeezing or shearing and provide
protection against parts that might come loose.
Covers and cladding must be positioned at a suitable distance or be
arranged so that there is no access to any moving parts within.
Covers and cladding must also be attached if the moving parts of the
torque flange are installed outside peoples' movement and operating
range.
The only permitted exceptions to the above requirements are if the various
parts and assemblies of the machine are already fully protected by the design
of the machine or by existing safety precautions.
Warranty
In the case of complaints, a warranty can only be given if the torque flange is
returned in the original packaging.

1 Torque flange versions
In the case of option 2 “Electrical configuration", the T10FS torque flange
exists in versions KF1, SF1 and SU2. The difference between these versions
lies in the electrical inputs and outputs on the stator, the rotors are the same
for all the versions of a measuring range. Alternatively, versions SF1 and SU2
can be equipped with a magnetic or optical speed measuring system (in the
case of the optical system, with or without a reference pulse).
