f Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
Guard locking by solenoid force: ¨ Activate
guard locking.
f
The machine must not start automatically.
f
It must not be possible to open the safety guard.
3. Enable operation in the control system.
f
It must not be possible to deactivate the guard locking
as long as operation is enabled.
4. Disable operation in the control system and
deactivate guard locking.
f
The safety guard must remain locked until there is no
longer any risk of injury.
f
It must not be possible to start the machine as long as
the guard locking is deactivated.
Repeat steps 2 - 4 for each safety guard.
Inspection and service
If damage or wear is found, the complete switch
and actuator assembly must be replaced.
Replacement of individual parts or assemblies is
not permitted!
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
sealing of cable entry
f
loose cable connections or plug connectors.
Note:The year of manufacture can be seen in the bottom,
right corner of the rating plate.
Exclusion of liability under the following
circumstances
f
incorrect use
f
non-compliance with safety regulations
f
non-compliance with safety regulations
f
failure to perform functional checks.

Functional check
Warning! Danger of fatal injury as a result of faults
in installation and functional check.
Before carrying out the functional check, make sure
that there are no persons in the danger area.
Observe the valid accident prevention regulations.
After installation and any fault, the safety function must
be fully checked. Proceed as follows:
f Mechanical function test
The actuator must slide easily into the actuating head.
Close the safety guard several times to check the
function.
