Safety instructions
Accident prevention
The applicable accident prevention regulations from employers' liability
insurance associations must be taken into account, even though the stated
load in the destructive range is well in excess of the full scale value.
Additional safety precautions
Load cells cannot (as passive transducers) implement any (safety-relevant)
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 load cells would cause injury
to persons or damage to equipment, the user must take appropriate additional
safety measures that meet at least the requirements of applicable safety and
accident prevention regulations (e.g. automatic emergency shutdown, overload
protection, catch straps or chains, or other fall protection).
The electronic processor 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
Load cells are state-of-the-art and reliable. Transducers can give rise to
residual dangers if they are mounted, installed, used and operated
inappropriately or by untrained personnel. Everyone involved with siting,
starting up, operating or repairing a load cell must have read and understood
the mounting instructions and in particular the technical safety instructions.
Load cells may be damaged or destroyed by improper use or non-compliance
with the mounting and operating manual, these safety instructions or any other
applicable safety regulations (safety and accident prevention regulations of
employers' liability insurance associations) when handling the load cells. Load
cells can break, particularly if overloaded. The breakage of a load cell can also
cause damage to property or injury to persons in the vicinity of the load cell.
If load cells are not used according to their designated use, or if the safety
instructions or specifications in the mounting and operating manual are
ignored, it is also possible that the load cells may fail or malfunction, with the
result that persons or property may be affected (due to the loads acting on or
being monitored by the load cells).
