6.2.
Guard locking on version CTP-I2
(guard locking actuated by power-ON and released by spring force)
Activating guard locking:
Apply auxiliary power to the solenoid and set AS-Interface output bit D0.
Releasing guard locking:
No auxiliary power at the solenoid and/or clear AS-Interface output bit D0.
The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the solenoid is
not controlled (D0=0) or if auxiliary power is switched off, guard locking is released and the guard can be opened directly!
If the solenoid is controlled via the AS-Interface bus (D0=1) and auxiliary power is applied to the solenoid, the guard locking
pin is held in extended position and the guard is locked.
