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 hingeA 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 in the evaluation module |
| OL | Guard locking solenoid in locked position |
| OI | Diagnostics; there is a fault |
Pushbutton
| S1 | 1 NO contact, illuminated |
Lens setThe color of the pushbutton can be selected using the lens set included (5 colors). Item no.: 120344 (see Accessories)
