6.5.
Guard locking on version CTP-LBI
(Guard locking actuated by spring force and released by power-ON)
Activating guard locking:
close guard; no voltage at control input IMP
Releasing guard locking:
apply voltage to control input IMP.
The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking remains active and the guard cannot be opened directly.
If the guard is opened when the power supply is interrupted and is then closed, the guard locking pin will be pushed down
and held in this position. This prevents people from being locked in unintentionally.
