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:
Mechanical function test
The guard locking pin must move easily to the locked
position. For checking, close the safety guard several
times and extend and retract guard locking pin.
Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
Guard locking by solenoid force: Activate
guard locking.
The machine must not start automatically.
It must not be possible to open the safety guard.
3. Enable operation in the control system.
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.
The safety guard must remain locked until there is
no longer any risk of injury.
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.
Service and inspection
If damage or wear is found, the complete switch
must be replaced.
Replacement of individual parts or assemblies
is not permitted!
Do not grease guard locking pin.
No servicing is required, but regular inspection of
the following is necessary to ensure trouble-free long-
term operation:
correct switching function
secure mounting of components
dirt and wear
sealing of cable entry
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
incorrect use
non-observance of the safety instructions
non-compliance with safety regulations
failure to perform functional checks.
