Function checks before initial commissioning

7.2.1

Function check of the brake

If a fault or malfunction arises during the function check, you can find important information for
troubleshooting in the chapter Troubleshooting and fault elimination, Page 71. If the fault cannot be fixed
or eliminated, please contact your customer service.
7.2.2

Release / voltage control

1. Switch off the supply to the motor and brake securely.
2. When switching on the brake supply, make sure that the motor DOES NOT start up (e.g. remove the
two bridges on the motor terminals).
– Do not disconnect the supply connections to the brake.
– If the rectifier for the brake supply is connected to the neutral point of the motor, also connect the
neutral conductor to this connection.
3. Micro-switch option - release monitoring: Check that the switching state is correct on the micro-switch:
the brake is applied.
4. Micro-switch option - wear monitoring: Check that the switching state is correct on the micro-switch:
the brake is NOT worn.
5. Switch the power on.
6. Measure the DC voltage at the brake.
– Compare the measured voltage to the voltage specified on the name plate. A deviation of up to
10% is permitted.
– When using bridge/half-wave rectifiers: After switching to one-way voltage, the measured DC
voltage may drop to 45% of the voltage specified on the name plate.
7. Micro-switch option - release monitoring: Check that the switching state is correct on the micro-switch:
the brake is released.
8. Check the air gap s
9. Switch off the supply to the motor and brake securely.
10. Connect the bridges to the motor terminals. Remove any extra neutral conductor.
11. Micro-switch option - wear monitoring: Adjust the air gap to s
gap, Page 40).
12. Micro-switch option - wear monitoring: Check that the switching state is correct on the micro-switch:
the brake is worn.
13. Adjust the air gap to s
14. If necessary, deactivate mechanical shutdown of the system.

DANGER
Danger: rotating parts!
Your system should be mechanically immobilized in the event that it could start moving
when the brake is released.
. The air gap must be zero and the rotor must rotate freely.
