Operating Instructions
Safety System MGBS-P-L.-AP…
EN
Important!
If the guard is open when the power supply is interrupted and is then closed, guard locking is activated.
This can lead to persons being locked in unintentionally.
The tongue on the handle module cannot be pulled out of the locking module and the guard is locked as long as the guard
locking pin is extended.
If a voltage is applied to the guard locking solenoid, the guard locking pin is retracted and the tongue on the handle module
is released. The guard can be opened.

Guard locking for version MGBS-L2
(guard locking actuated by power-ON and released by spring force)
Important!
Use as guard locking for personnel protection is possible only in special cases, after strict assessment
of the accident risk (see EN ISO 14119:2013, section 5.7.1)!
Activating guard locking:
apply voltage to the solenoid.
Releasing guard locking:
disconnect voltage from the solenoid.
The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the voltage is
interrupted at the solenoid, the guard locking is released and the guard can be opened directly!
The guard can be opened as long as no voltage is applied to the guard locking solenoid.
If a voltage is applied to the guard locking solenoid, the guard locking pin is held in the extended position and the guard is
locked.
