Safety instructions

In cases where a breakage may cause injury to persons or damage to equip-
ment, the user must take appropriate safety measures (such as fall protection,
overload protection, etc.). Safe and trouble-free operation of the load cells re-
quires 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 specifica-
tions.
Use in accordance with the regulations
Z7A/... type load cells have been designed for weighing applications. Use for
any additional purpose shall be deemed to be not in accordance with the re-
gulations.
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 ap-
plies 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 sensiti-
vity, the load cells have not been designed with the safety factors normally ap-
plied in machine design. The load cell is not a safety element within the mea-
ning of its use in accordance with the regulations. The measuring signal
processing electronics has to be designed in such a way that with a measur-
ing 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 untrained 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 technical safety instructions.
