Setup and functional check
Pay attention to the information in the system manual
for the evaluation unit used during setup.
Danger of fatal injuries as a result of faults in
installation and functional check.
f
Before carrying out the functional check,
make sure that there are no persons in the
danger area.
f
Observe the valid accident prevention regula-
tions.
After installation and any fault, the safety function
must be fully checked. Proceed as follows:
f
Switch on operating voltage.
The machine must not start automatically.
f
Close all safety guards.
f
Activate the guard locking.
f
Test the locking force by trying to open the safety
guard. The adhesive force of 500 N or 1,000 N is
attained when U
CM
is applied.

Service and inspection
No servicing is required, but regular inspection of the
following is necessary to ensure trouble-free long-term
operation:
f
correct switching function
f
secure mounting of components
f
dirt and wear
f
loose cable connections or plug connectors.
If damage or wear is found, the complete
read head and actuator assembly must be
replaced.
Replacement of individual parts or assemblies
is not permitted!
Exclusion of liability under the following
circumstances
f
incorrect use
f
non-compliance with safety regulations
f
installation and electrical connection not per-
formed by authorized personnel.
f
failure to perform functional checks.
