Door stop A mechanical door stop is permanently integrated into the evaluation module of the MGB. A marking on the stop makes adjustment easier. LED indicator The LED indicator indicates all important system and status information. Guard locking type

MGB-L1...

The locking arm is kept in locked position by spring force and is unlocked by solenoid force (closed-circuit current principle).

Auxiliary release For releasing the guard locking, e.g. in case of a power failure. Monitoring outputs

OT	Bolt tongue inserted into the evaluation module
OL	Guard locking solenoid in locked position
OI	Diagnostics, there is a fault

Escape releaseThe escape release enables people accidentally shut in to open the guard locked door from the danger zone.
