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 safety switchgear
2 Check max angular misalignment (see “Mounting” part)
3 Check the integrity of the cable entry and connections
4 Check the switch enclosure for damage
5 Remove particles of dust and soiling
7.2 Maintenance
In the case of correct installation and adequate use, the safety
switchgear features maintenance-free functionality A regular visual
inspection and functional test, including the following steps, is
recommended:
• Check of the safety function
• Check the fixing of the safety switch and the actuator
• Check max axial misalignment of actuator and solenoid interlock
• Check max angular misalignment (see “Mounting” part)
• Check the integrity of the cable entry and connections
• Check the switch enclosure for damages
• Remove soiling
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators
Damaged or defective components must be replaced.
