1. The switching contact for the brake must be open.
2. Remove two bridges from the motor terminals to de-energise the motor.
- Do not disconnect the supply voltage for the brake. Apply DC voltage to the brake.
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.
6. Measure the DC voltage at the brake:
- The measured DC voltage after the over-excitation time (see bridge/half-wave rectifier, 34)
must correspond to the holding voltage (see table 5). A deviation of ±10 % is permissible.
7. Check the air gap "s
L
".
- It must be zero and the rotor must rotate freely.
8. Check the switching status of the microswitch (see table 6).
9. Open the switching contact for the brake.
- The brake is applied.
10. Check the switching status of the microswitch (see table 6).
11. Switch off DC voltage for the brake.
12. Screw the bridges onto the motor terminals.
13. If necessary, remove the neutral conductor from the neutral point (step 2).
NOTICE
If the brake is connected to the neutral point of the motor, the PE conductor must also be con-
nected to this point.
