6 Commissioning and operation
6.1 Important notes
❚ The brakes are dimensioned in such a way that the specified rated torques are reached safely after a
short run-in process.
❚
However, as the organic friction linings used do not all have identical properties and because environ-
mental conditions can vary, deviations from the specified braking torques are possible. These must be
taken into account in the form of appropriate dimensioning tolerances. Increased breakaway torque is
common, in particular after long downtimes in humid environments where temperatures vary.
❚ Check the braking torque when the brake is being used on the customer's friction surfaces.
❚ If the brake is used as a pure holding brake without dynamic load, the friction lining must be reactivated
regularly.
6.2 Function checks before commissioning
6.2.1 Functional checks
Brake with microswitch
DANGER
❚ The live connections and the rotating rotor must not be touched.
❚ The drive must not be running when checking the brake.
DANGER
Danger: rotating parts!
The brake must be free of residual torque. The motor must not run!
DANGER
There is a risk of injury by electrical shock!
Live connections must not be touched.
