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). |
Guard lock monitoring switched offAs the default setting on delivery, guard lock monitoring is switched off via the internal DIP switches on these evaluation modules. Consequently, guard locking is suitable only for process protection. Safety outputs FO1A and FO1B do not depend on the state of guard locking.
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, illuminated |
S3 | 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)
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.
