6.2. Guard locking for version MGB-L2
(guard locking actuated by power-ON and released by spring force)
Important!
Use as guard locking for personnel protection is possible only in special cases, after strict assessment
of the accident risk (see EN ISO 14119:2013, section 5.7.1)!
Activating guard locking:
apply voltage to the solenoid.
Releasing guard locking:
disconnect voltage from the solenoid.
The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the voltage is
interrupted at the solenoid, the guard locking is released and the guard can be opened directly!
The guard can be opened as long as no voltage is applied to the guard locking solenoid.
When voltage is applied to the guard locking solenoid, the locking arm is held in the locked position and the guard is locked.
