Closing safety guard and activating guard locking
The safety door can be opened as long as the lift tappet is held in the extended
position. Switching the guard locking solenoid on via AS-Interface output bit D0
releases the lift tappet. The actuator's guard locking pin can now press the lift tap-
pet down. The safety door is locked and the solenoid monitoring contact is closed
as soon as the guard locking pin is fully inserted into the recess. The complete
safety code sequence is sent via AS-Interface input bits D0 to D3.
Deactivating guard locking
Switching the guard locking solenoid off via AS-Interface output bit D0 extends the
lift tappet and raises the actuator's guard locking pin over the edge of the recess.
The half-sequence is sent via AS-Interface input bits D0 and D1 in every bus cycle.
Opening safety guard
Opening the safety door moves the actuator out of the operating distance. The
values 0, 0, 0, 0 are continuously sent via AS-Interface input bits D0 to D3.
