Safety instructions
S Limits of electrical loading capacity
When several force transducers are connected, it must be noted that the load/
force distribution is not always uniform.
Use as a machine element
Force transducers can be used as machine elements. When used in this
manner, it must be noted that, to favor greater sensitivity, the force transducers
were not designed with the safety factors usual in mechanical engineering.
Please refer here to the section "Load-carrying capacity limits", and to the
specifications.
Additional safety precautions
Force transducers cannot (as passive transducers) implement any safety-rel­
evant cutoffs. This requires additional components and constructive measures,
for which the installer and operator of the plant is responsible.
In cases where a breakage or malfunction of the force transducer would cause
injury to persons or damage to equipment, the user must take appropriate ad­
ditional safety measures that meet at least the requirements of applicable
safety and accident prevention regulations (e.g. automatic emergency shut­
down, overload protection, catch straps or chains, or other fall protection).
The electronics conditioning the measurement signal should be designed so
that measurement signal failure does not subsequently cause damage.
General dangers of failing to follow the safety instructions
The force transducers are state-of-the-art and failsafe. There may be dangers
involved if the transducers are mounted, sited, installed and operated inappro­
priately, or by untrained personnel. Every person involved with siting, 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 and operating in­
structions, these safety instructions or any other applicable safety regulations
(safety and accident prevention regulations of the Employers' Liability Insur­
ance Association) when using the force transducers. Force transducers can
break, particularly if overloaded. The breakage of a force transducer can also
