Safety instructions
4A05750_02_XA0_00 HBM: public PWS
Use as a machine element
The load cells can be used as machine elements. When used in this manner, it
must be noted that, to favor greater sensitivity, the load cell is not designed
with the safety factors usual in mechanical engineering. Please refer here to
the section “Loading capacity limits" and to the specifications.
Accident prevention
The prevailing accident prevention regulations must be taken into account,
even though the maximum capacity values in the destructive range are 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 layout of the electronics conditioning the measurement signal should be
such that measurement signal failure does not cause damage.
General dangers of failing to follow the safety instructions
Load cells are state‐of‐the‐art and reliable. Transducers can give rise to resid
ual dangers if they are incorrectly operated or inappropriately mounted,
installed and operated 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. The
load cells can be damaged or destroyed by non‐designated use of the load
cells or by non‐compliance with the mounting and operating instructions, these
safety instructions or any other applicable safety regulations (BG safety and
accident prevention regulations) when using the load cells. Load cells can
break, particularly in the case of overloading. The breakage of a load cell can
