7. Check counter friction face:
A Flange
-
Maximum run-in depth = 30 % of rated air gap
13.
-
In the case of strong scoring, replace the flange.
-
In the case of thermal damage (dark blue tarnishing), replace the flange.
B End shield
-
Maximum run-in depth = 30 % of rated air gap
13.
-
In case of strong scoring, reprocess the end shield
20.
8. Assemble the brake,
9. Connect the supply cable.
10. Recommission the brake,
34.

Release / voltage
1. Observe the brake functionality while the drive is operating. The armature plate must be attracted and
the rotor must move without residual torque.
2. Measure the DC voltage at the brake.
-
Compare the DC voltage with the voltage indicated on the name plate. A deviation of 10 % is per-
missible.
NOTICE
After replacing the rotor, the original braking torque will not be reached until the run-in opera-
tion for the friction surfaces has been completed. After replacing the rotor, the run-in armature
plates and the flanges have an increased initial rate of wear.
