SAFETY INSTRUCTIONS
1 SAFETY INSTRUCTIONS
In cases where a breakage could injure persons or damage equipment, the user must
take appropriate safety measures (such as safety devices to protect against falls,
collapses or overloads). For safe and trouble‐free operation, 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 specifications.
Intended use
Load cells are designed for metrological applications. Use for any additional purpose
shall be deemed to be not as intended.
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 tank weighing, for example). In these
situations, you must make sure that for greater sensitivity, 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 appropriate use. 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. Load cells can give rise to residual dangers if
they are inappropriately installed and operated by untrained personnel.
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.
Residual dangers
The scope of supply and performance of the load cells covers only a small area of
weighing technology. In addition, equipment planners, installers and operators should
plan, implement and respond to the safety engineering considerations of the weighing
technology in such a way as to minimize residual dangers. On‐site regulations must be
complied with at all times. Reference must be made to the residual dangers associated
with the weighing technology.
