Guard locking type

MGB-L2...

The locking arm is held in the locked position by solenoid force and is unlocked by spring force when the solenoid is switched off (open-circuit current principle, electrically 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

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

Emergency stop device

S1	Two positively driven contacts and one NO contact (e.g. monitoring contact), emergency stop with turn-to-reset, not illuminated

Pushbutton

S2	One NO contact, illuminated
S3	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.
