1)
The leading diagnosis message through bit 1 indicates whether locking or unlocking of the guard system is possible. The solenoid interlock
cannot be unlocked if e.g. the door pulls the turret out of its rest position beyond the set latching force. This can occur if doors are heavily
distorted or when pulling the door. The solenoid interlock can only be locked if the turret is in the rest position, i.e. the latching force is
sufficient to pull the guard system into the correct position.

7 Set-up and maintenance
The safety function of the safety components must be tested. 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:
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. angular misalignment (see "Mounting" part).
4. Fitting and integrity of the cable connections.
5. Check the switch enclosure for damages.
6. Remove particles of dust and soiling.
7. For versions with emergency exit and emergency release the following should also be considered:
- For versions with emergency exit it must be possible to open the guard system from within the hazardous area;
it must not be possible that the guard system is blocked from the inside.
- By operating the emergency release lever outside of the hazardous zone it must be possible to open the guard
system.
