Maintenance and repair
7.1
Inspection intervals
The spring-applied brake must be checked during the prescribed inspections of the drive system in which it
is installed.
The service life of the brake before replacement does not only depend on the number of emergency brak-
ings. The wear of the brake friction linings varies depending on the operating conditions. The friction work
possible before replacement decreases with every braking when the switching energy increases.

Inspections
7.2.1
Braking torque / delay check.
1. Switch on the power supply for the brake.
2. Use a feeler gauge to check the air gap "s

in the reverse order of the assembly (
1. Switch on the current for the brake
or
screw in the transport screws (M6x65 with Ø23 washer).
2. Loosen the fixing screws at the guide sleeves (Figure 1).
3. Remove the brake radially from the brake disc.
4. Switch off the power supply and disconnect the connecting cables.
