Inspection and Maintenance
Installing a new
brake disk When installing a new brake disk, inspect the other removed parts as well and install
new ones if necessary.
1. Isolate MOVIMOT
®
from the supply, safeguarding it against unintentional power-up.
2. Remove the following:
– Proximity sensor NV16 / NV26, if installed
– Flange cover or fan guard (21), circlip (20) and fan (19)
3. Remove the rubber sealing collar (5).
Remove the manual brake release: Setting nuts (18), conical coil springs (17), studs
(16), releasing lever (15).
4. Loosen hexagon nuts (10e), carefully pull off the coil body (12) (Caution, brake ca-
ble!), and take out the brake springs (11).
5. Remove the damping plate (9), pressure plate (8) and brake disk (7, 7b) and clean
the brake components.
6. Install a new brake disk.
7. Re-install brake components (except rubber sealing collar, fan and fan guard). Set
working air gap (page 145, Points 5 to 7).
8. With manual brake release (type HF or HR):
Set the floating clearance via the setting nuts between the conical coil springs
(pressed flat) and setting nuts (see the following figure).

Important: This floating clearance is necessary so that the pressure plate can
move up as the brake lining wears.
Note:
• The lockable manual brake release (type HF) is already released if a resistance is
encountered when operating the grub screw.
• The self-reengaging manual brake release (type HR) can be operated with normal
hand pressure.
Important: In brake motors with self-reengaging manual brake release, the manu-
al brake release lever must be removed after startup/maintenance. A bracket is
provided for storing it on the outside of the motor.
