INSPEcTIONS PrIOr TO STArT-UP Of THE brAKE
6 Start-up
6.1 Inspections prior to start-up of the brake
6.1.1 visual inspection
• Do connection and rated voltage (magnet marking) agree?
• Are external damages visible?
• Are there impurities in the functional area or foreign bodies in the air gap of the
brake?
6.1.2 Load-free testing
• Ensure that the brake is unloaded.
• Release/close the brake by switching the voltage supply.
NOTICE
Damage due to non-observance!
►
Do not put into operation if one of the tests is not OK.
6.1.3 run in of the brake
NOTICE
Damage due to insufficient rated braking torque!
►
The rated braking torque is only reached after the brake has run in.
To run in the brake, some dynamic braking must be carried out. Depending on the brake
size and corresponding speed, we recommend a slip and idle time of 2 seconds each
for 10 switching operations.

Table 9:
Run in of the brake
NOTICE
Influences on the brake torque!
► The braking torque may deviate from the specified values depend
-
ing on the mounting situation as well as the environmental condi-
tions such as temperature, contamination or corresponding ageing.
► Using the brake purely as a holding brake can lead to a drop in
braking torque, so that regular refreshment must be carried out as
part of maintenance.
A maintenance interval of 4 weeks is recommended for normal industrial ap-
plications.
