7 Set-up and maintenance
7.1 Functional testing
The safety function of the safety components must be tested. The following conditions must be previously checked and
met:
1. Check max. axial misalignment of actuator and solenoid interlock.
2. Check max. angle displacement.
3. Make sure that it is not possible to lift the actuator in the Z axis above the extended bolt.
4. • Check for a secure installation of the actuator and the solenoid interlock
5. Fitting and integrity of the cable connections.
6. Check the switch enclosure for damages
7. Remove particles of dust and soiling.
8. For versions with emergency exit, the following should also be considered:
It should be possible to open the guard system from within the hazardous area; it should not be possible to lock
the safety guard from inside.
7.2 Maintenance
In the case of correct installation and intended use, the safety switchgear is maintenance-free.
A regular visual inspection and functional test, including the following steps, is recommended:
1. • Check for a secure installation of the actuator and the solenoid interlock
2. Check max. axial misalignment of actuator and solenoid interlock.
3. Check max. angle displacement.
4. Make sure that it is not possible to lift the actuator in the Z axis above the extended bolt.
5. Fitting and integrity of the cable connections.
6. Check the switch enclosure for damages
7. Remove particles of dust and soiling.
Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for
2
instance by means of replacement actuators.
Damaged or defective components must be replaced.

8 Disassembly and disposal
8.1 Disassembly
The safety switchgear must be disassembled in a de-energised condition only.
