Commissioning and operation
Important notes
DANGER
Danger: rotating parts!
¾
The running rotor must not be touched.
¾
Take structural design measures on your final product and implement organizational
safety rules to ensure that nobody can touch a rotor.
DANGER
There is a risk of injury by electrical shock!
The live connections must not be touched.
¾
The brakes are dimensioned in such a way that the specified rated torques are reached safely after a
short run-in period.
¾
Increased breakaway torque is common, in particular after long downtimes in humid environments
where temperatures vary.
¾
Before the initial commissioning, check the braking torque when the brake is being used on the cus-
tomer's friction surfaces.
¾
If the brake is used as a pure holding brake without any dynamic load, the friction lining must be react-
ivated regularly by implementing the friction work.
7.1
Function checks before initial commissioning
7.1.1
Brake with micro-switch
1. The switching contact for the brake must be open.
2. Remove two bridges from the motor terminals to de-energize the motor.
– Do not switch off the voltage supply to the brake.
NOTICE
If the brake is connected via the neutral point of the motor, this connection
must also be used for connecting the neutral conductor.
3. Apply DC voltage to the brake.
4. Measure the AC voltage at the motor terminals. The measured level must be zero.
5. Close the switching contact for the brake.
– The brake is released.
