Manual Release Adjustment
CAUTION: Load to be removed or blocked. Brake will be inoperative during this procedure.
The manual release (7) may require adjustment after replacing the electromagnet assembly (50A & 32), magnet (50A), or
pressure plate (32). It also may be required if adjustments are made on the pivot post nut (44).
The release is working properly if:
a) You turn release (7) clockwise to stop and the brake is released;
b) The release returns to its normal position automatically when power is applied to the magnet.
NOTE: Cover (67) must be removed to make this adjustment.
1. To adjust: Set air gap “D” as described under “Wear Adjustment”.
2. If the brake does not release, turn the adjusting screw above the manual release cam (12) on the pressure plate (32)
counterclockwise and try again.
3. If the manual release (7) does not return to its normal position automatically, turn the adjusting screw above the manual
release cam (12) on the pressure plate (32) clockwise and try again.
NOTE: You may have to repeat Steps 2 or 3 to get the release to operate properly. It is important that the manual release
returns to its normal position automatically when power is applied to the magnet.
