SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
Intended use
The force transducers of the Z4A series are designed exclusively for measuring static
and dynamic tensile and/or compressive forces within the load limits specified in the
technical data. Any other use is not appropriate.
To ensure safe operation, the regulations in the mounting instructions, together with the
following safety rules and regulations, and the data specified in the technical data sheets,
must be complied with. During use, compliance with the legal and safety requirements for
the relevant application is also essential.
The force transducers are not intended for use as safety components. Please also refer
to the “Additional safety precautions” in this 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
SBending moment limits
STorque limits
SBreaking forces
SPermissible dynamic loads
STemperature limits
SLimits of electrical load-carrying capacity
Please note that when several force transducers are interconnected, the load/force distri
bution is not always uniform, so an individual force transducer may be overloaded even
though the cumulative signal has yet to reach the sum of the nominal (rated) forces of the
sensors connected in parallel.
Use as machine elements
Force transducers can be used as machine elements. In this application, it should be
noted that, for the sake of high measurement sensitivity, the force transducers were not
designed with the safety factors commonly used in machine building. Please refer to the
“Load-carrying capacity limits” section and the specifications.

SAFETY INSTRUCTIONS

Accident prevention
Pay attention to the prevailing accident prevention regulations, even though the breaking
force is well in excess of the full scale value. This applies in particular to transportation
and installation.
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 opera
tor of the plant is responsible. Wherever breakage or malfunction of the force transduc
ers may result in injury to persons or damage to property, the user must take appropriate
additional safety precautions that at least meet the requirements of the relevant accident
prevention regulations (e.g. automatic emergency shutdowns, overload protection, safety
straps or chains, or other fall protection devices).
The electronics processing the measurement signal must be designed in such a way that
no consequential damage can occur if the signal fails.
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.
Force transducers can be damaged or destroyed if used for purposes other than their
intended use or in the event of non-compliance with the installation and operating man
ual, these safety instructions or other applicable safety regulations (relevant accident
prevention regulations). Force transducers can break, particularly if overloaded. The
breakage of a force transducer can also cause damage to property or injury to persons in
the vicinity of the force transducer.
Furthermore, if force transducers are not used according to their intended use, or if the
safety instructions or specifications in the installation and operating manual are ignored,
the force transducer may fail or malfunction, with a possible impact on persons or prop
erty (from the loads acting on or being monitored by the force transducer).
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 require
the use of electronic signal conditioning. In addition, plant planners, equippers and opera
tors are responsible for planning and implementing force measurement systems in such
a way as to minimize residual risks. Pertinent national and local regulations must be com
plied with. There must be reference to the remaining dangers associated with force
measurement technology.

SAFETY INSTRUCTIONS
Conversions and modifications
The design or safety engineering of the transducer must not be modified without our
express permission. Any modification will void our liability for resulting damage.
Maintenance
Z4A force transducers are maintenance free.
Disposal
In accordance with national and local environmental protection, material recovery and
recycling regulations, old transducers that are no longer serviceable must be disposed of
separately from normal household waste.
For more information on disposal,please contact your local authority or the dealer from
whom you purchased the product.
Qualified personnel
Qualified personnel are persons who are familiar with the installation, assembly, commis
sioning,operation and disassembly of the product, and who have qualifications appropri
ate to their work. This includes people who meet at least one of the three following crite
ria:
1. Knowledge of the safety concepts of automation technology is a requirement and as
project personnel, you must be familiar with these concepts.
2. 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.
3. As commissioning or service engineers, you have successfully completed the training
to repair automation plants. You are also authorized to operate, ground and mark cir
cuits and equipment in accordance with safety engineering standards.
During use, compliance with the legal and safety requirements for the relevant applica
tion is also essential. The same also applies to the use of accessories.
The force transducer may only be installed by qualified personnel, strictly in accordance
with the specifications and with the safety requirements and regulations.
