Guard locking type
| MGB-L2… | The locking arm is kept in locked position by solenoid force and unlocked by spring force when the solenoid is switched off (open-circuit current principle, electrically 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 |
| OI | Diagnostics; there is a fault |
Emergency stop device
| S1 | 2 positively driven NC contacts, emergency stop with turn-to-reset, not illuminated |
Pushbutton
| S2 | 1 NO contact, white, illuminated |
| S3 | 1 NO contact, yellow, illuminated |
Key-operated rotary switch
| S4 | Key-operated rotary switch with 2 positions (form L, 90°). The switch latches in both positions, but it can only be removed in position 0. |
Adhesive labelsDevices with adhesive labels have pre-formed recesses. The adhesive labels enclosed (standard size 12.5 x 27 mm) can be affixed in these recesses.
