• Operation
For brakes fitted with a DMD, supply the brake coil separately
from the motor. Once the brake is released, supply the
electromagnet on the latch control plate. Once the latch
contact is triggered, power off the brake coil then the control
plate. The brake is maintained in the released position. When
brake power is restored, locking drops automatically and the
brake is operational.

.
- Unscrew the control rods of the levers
1502
and
1605
