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
| 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 |
Pushbutton
| S1 | One NO contact, illuminated |
| S2 | 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.
