Maintenance work

Note
Completely replace brakes with defective armature disks, springs or flanges.
When performing inspection and maintenance work always observe the following:
• Use a brake cleaning agent to remove any impurities as a result of oil and grease
• Possibly replace the brake after the cause has been clarified.
• Remove dirt and particles in the air gap between the solenoid and armature disk as they
can impair the function.
• After replacing the rotor, the original braking torque is only reached after the friction
surfaces have run-in. After a rotor has been changed, increased initial wear occurs for
armature disks and flanges that have been run-in.
Testing the brake
Note
If the safety-related brake is operated according to the regulations listed in these instructions,
then simplified testing/maintenance is permissible with the brake mounted.
After removing the brake, the extended testing/maintenance is no longer necessary.

Check the air gap (CAUTION: if the air
gap must be readjusted, then an
extended test is required after
removing the brake)
Test the release function and control
Adjust the air gap
Check the rotor thickness
Check rotor teeth backlash, replace
worn rotors
Any movement/deflection of the torque
support at the guide parts and armature
disk
Check the springs for any damage
Check the armature disk and flange
and/or mating surfaces
- thermal damage (dark blue tarnishing)
- Flatness depending on the size
Max. run-in depth = nominal air gap
