Safety instructions
PW22 A2443-3.0 HBM: public 3
1 Safety instructions
In cases where a breakage would cause injury to persons or damage to equip
ment, the user must take appropriate safety measures (such as safety devices
to protect against falls, collapses or overloads). For safe and trouble‐free op
eration, load cells must not only be correctly transported, stored, sited and
mounted but must also be carefully operated and maintained.
It is essential to comply with the relevant accident prevention regulations. In
particular you should take into account the limit loads quoted in the specifica
tions.
Appropriate use
Load cells are designed for metrological applications. Use for any additional
purpose shall be deemed to be not appropriate.
In the interests of safety, load cells should only be operated as described in the
Mounting Instructions. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Load cells can be used as machine elements (for container and silo weighing,
for example). In these situations, you must make sure that for greater sensitiv
ity, the load cells are not constructed with the customary safety factors found in
machine design. Load cells are not safety elements within the meaning of ap
propriate use. The layout of the electronics conditioning the measurement sig
nal 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. Load cells can give rise to remain
ing dangers if they are inappropriately installed and operated by untrained per
sonnel.
Everyone involved with siting, starting up, maintaining or repairing a load cell
must have read and understood the Mounting Instructions and in particular the
technical safety instructions.
