SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Intended use
Force transducers in the C5 series are designed solely for measuring static and dynamic
compressive forces within the load limits stated in the specifications. Any other use is
not the intended use. To ensure safe operation, it is essential to comply with the
regulations in the mounting instructions, the safety requirements listed below, and the
data specified in the supplied technical data sheets. It is also essential to observe the
applicable legal and safety regulations for the relevant application.
Force transducers are not intended for use as safety components. Please also refer to
the “Additional safety precautions” section. Proper and safe operation of force
transducers requires proper transportation, correct storage, setup and mounting, and
careful operation.
Load-carrying capacity limits
The information in the technical data sheets must be observed when using the force
transducers. The respective specified maximum loads in particular must never be
exceeded. The values specified in the technical data sheets must not be exceeded:
SForce limits
SLateral force limits
SMaximum eccentricity
SBreaking forces
SPermissible dynamic loads
STemperature limits
SElectrical load limits
Please note that when several force transducers are interconnected, the load/force
distribution is not always uniform.
Use as machine elements
Force transducers can be used as machine elements. When used in this manner, note
that to favor greater sensitivity, force transducers were not designed with the safety
factors usual in mechanical engineering. Please refer here to the "Load-carrying capacity
limits" section and to the specifications.
Accident prevention
The prevailing accident prevention regulations must be taken into account, even though
the nominal (rated) force values in the destructive range are well in excess of the full
scale value.

SAFETY INSTRUCTIONS

Additional safety precautions
The force transducers (as passive transducers) cannot execute (safety) shutdowns. This
requires additional components and design measures, for which the installer and
operator of the plant is responsible.
Wherever,in the event of breakage or malfunction of the force transducers, people or
property may be injured, the user must take suitable additional safety precautions which
at least comply with the relevant accident prevention regulations (e.g. automatic
emergency stop, overload protection, catch straps or chains, or other fall protection
devices).
The electronics that processes the measurement signal should be designed so that
failure of the measurement signal cannot lead to secondary failures.
General dangers of failing to follow the safety instructions
Force transducers are state-of-the-art and failsafe. The transducers can be dangerous if
they are mounted, set up or operated improperly, or by untrained personnel. Every person
involved in setting up, starting up, operating or repairing a force transducer must have
read and understood the mounting instructions and in particular the technical safety
instructions. The force transducers can be damaged or destroyed by non-designated use
of the force transducer or by non-compliance with the mounting manual, these safety
instructions or other applicable safety regulations (safety and accident prevention
regulations of the Employers' Liability Insurance Association) when using the force trans
ducers. A force transducer can break, particularly if it is overloaded. The breakage of a
force transducer can cause damage to property or injury to persons in the vicinity of the
force transducer.
If force transducers are not used in accordance with their intended purpose, or if the
safety instructions or the specifications in the mounting instructions are disregarded, the
force transducers may also fail or malfunction, with the result that (due to loads acting on
or monitored by the force transducers) people or property may be injured.
The scope of supply and performance of the transducer covers only a small area of force
measurement technology, as measurements with (resistive) strain gage sensors
presuppose the use of electronic signal processing. Equipment planners, installers and
operators should always plan, implement and respond to the safety engineering
considerations of force measurement technology in such a way as to minimize residual
dangers. Pertinent national and local regulations must be complied with.
Conversions and modifications
The design or safety engineering of the transducer must not be modified without our
express permission. Any modification shall exclude all liability on our part for any
resulting damage.

SAFETY INSTRUCTIONS
Maintenance
The force transducers of the C5 series are maintenance free. We recommend having the
force transducer calibrated at regular intervals.
Disposal
In accordance with national and local environmental protection and material recovery and
recycling regulations, old transducers that can no longer be used must be disposed of
separately and not with normal household garbage.
If you require more information about disposal, please contact your local authorities or
the dealer from whom you purchased the product.
Qualified personnel
Qualified personnel means persons entrusted with installing, mounting, starting up and
operating the product who possess the appropriate qualifications for their work.
This includes people who meet at least one of these three requirements:
SAs project personnel, you know and are familiar with the safety concepts of
automation technology.
SAs 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.
SAs a commissioning or service engineer, you have successfully completed training on
the repair of automation plants. Moreover, you are authorized to start up, ground and
label circuits and equipment in accordance with safety engineering standards.
During use, compliance with the legal and safety requirements for the relevant
application is also essential. The same applies to the use of accessories.
The force transducer may only be used by qualified personnel exclusively in accordance
with the technical data in conjunction with the safety rules and regulations.

3.3 Equipment variants
The C5 force transducer always comes supplied with a thrust piece.
The force transducer is available in different versions. The following options are
available:
1. Nominal (rated) force
You can purchase force transducers with nominal (rated) forces between 5 MN and
20 MN. The nominal (rated) force is the force at which the sensor provides the rated out
put specified on the type plate as the output signal.
2. Number of measuring bridges
You can purchase the force transducer with a single bridge (SB), in which case the C5
comes supplied with one measuring bridge. The double-bridge version (DB) is optionally
available. The C5 then comes supplied with two electrically isolated bridge circuits.

3. Bending moment bridges
You can purchase the force transducer with or without bending moment bridges (NB). If
you select the bending moment bridges option, the C5 comes with two electrically
isolated bending moment bridges.
The bending moments are recorded at 90 degrees to each other. Please note that no
characteristic value is specified for the bending moment bridges in the test report or in
the optional calibration certificate.
4. Transducer identification
You can purchase the force transducer with transducer identification (“TEDS”). TEDS
(Transducer Electronic Data Sheet) makes it possible to store the transducer data
(characteristic values) in a chip which can be read out by a connected measuring device.
With the double bridge version, or if you have selected optional bending moment bridges,
each measuring bridge is assigned its own TEDS. See also section 9, page 18.
5. Plug protection
On request, we can fit plug protection, consisting of a strong square tube, so that the plug
is protected against mechanical damage.
6. Plug version
The standard version of the force transducer is delivered with a bayonet connector. A
threaded connector can be supplied instead, if required. It is also possible to obtain the
force transducer with a fixed cable.
