Guard locking type

MGB-L1...

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

Door stopA mechanical door stop is permanently integrated into the evaluation module of the MGB. A marking on the stop makes adjustment easier. LED indicatorThe LED indicator indicates all important system and status information. Monitoring outputs

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

Pushbutton

S1	One NO contact, illuminated

Lens setThe color of the pushbutton can be selected using the lens set included (five colors). Item no.: 120344 (see Accessories) Escape releaseThe escape release enables people accidentally shut in to open the guard locked door from the danger zone. Multicode evaluationEvery suitable handle module is detected by the safety switch.
