clearance of 50.8 mm must be maintained. This
does not apply if the moving cables are equipped
with suitable insulation materials which possess an
identical or higher dielectric strength compared to
the other relevant parts of the system.
The operating voltage for the guard locking solenoid
must match the value on the rating plate (e.g. U
S
=
AC/DC 24 V).

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.
f Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
In case of 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.
f BI-state function test
1. Switch on operating voltage and close the
safety guard.
2. Switch operating voltage off.
f
It must not be possible to open the safety guard.
3. Switch on operating voltage.
4. Deactivate guard locking and open safety
guard
5. Switch operating voltage off.
f
It must be possible to close and open the safety
guard as required.
Repeat the function test 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
installation and electrical connection not per-
formed by authorized personnel
f
failure to perform functional checks.
