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 hinge
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.
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 |
Pushbuttons
| S1 | 1 NO contact, illuminated |
Lens set
The color of the pushbuttons can be selected using the color cover set included (5 colors). Item no.: 120344 (see Accessories)
