SAFETY INSTRUCTIONS

In cases where a breakage may cause injury to persons or damage to equipment, the
user must take appropriate safety measures (such as fall protection, overload protection,
etc.). Safe and trouble‐free operation of the load cells requires proper transportation,
correct storage, assembly and mounting as well as careful operation and maintenance.
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.
Use in accordance with the regulations
Z7A/... type load cells have been designed for weighing applications. Use for any addi­
tional purpose shall be deemed to be not in accordance with the regulations.
To ensure safe operation, the load cells should only be used as described in the Mounting
Instructions. It is also essential to observe the appropriate legal and safety regulations
for the application concerned during use. The same applies to the use of accessories.
The Z7A/... load cells can be used as machine components (e.g. with tank weighing).
Please note in these cases that, in order to provide a high sensitivity, the load cells have
not been designed with the safety factors normally applied in machine design. The load
cell is not a safety element within the meaning of its use in accordance with the regula­
tions. The measuring signal processing electronics has to be designed in such a way that
with a measuring signal failure no damages can occur.
General dangers due to non‐observance of the safety instructions
The Z7A/... load cells correspond to the state of the art and are fail‐safe. The load cells
can give rise to residual dangers if they are inappropriately installed and operated by un­
trained personnel.
Everyone involved with the installation, commissioning, maintenance or repair of a load
cell must have read and understood the Mounting Instructions and in particular the tech­
nical safety instructions.
Residual dangers
The scope of supply and performance of the load cells covers only a small part of weigh­
ing technology. In addition, equipment planners, installers and operators should plan, im­
plement and respond to the safety engineering considerations of weighing technology in
such a way as to minimize residual dangers. Prevailing regulations must be complied
with at all times. There must be reference to the residual dangers connected with weigh­
ing technology.
