![MGB-L2-ARA-BM5A1-S1-L-121181 (Order no. 121181)](https://assets2.euchner.de/files/88/17/ast_668817_xl.png)
Description
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). |
Guard lock monitoring switched off
As the default setting on delivery, guard lock monitoring is switched off via the internal DIP switches on these evaluation modules. Consequently, the guard locking is suitable only for process protection. Safety outputs FO1A and FO1B do not depend on the state of guard locking.
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
OT | Bolt tongue inserted into the evaluation module |
OI | Diagnostics; there is a fault |
Emergency stop device
S1 | 2 positively driven contacts, emergency stop with turn-to-reset, not illuminated |
Pushbuttons
S2 | 1 NO contact, illuminated |
S3 | 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)
Adhesive labels
Devices with adhesive labels have pre-formed recesses. The adhesive labels enclosed (standard size 12.5 x 27 mm) can be affixed in these recesses.
