Trouble shooting for the basic contol unit KR4 / KR 7
- Check fuse / Mains voltage
- Control unit is not enabled (ext. potential free contact closed)
- Check the thermal protective contact
- Connect thermal protective contact at the control Unit.
-
During operation with rotation monitor:
- Check distance of magnetic switch to the rotor
- Check connection of the magnetic switch at the
control Unit
- Check if V belt has come off
- Check V belt tension
During operation without rotation monitor:
- Alter programming of the Control Unit
(See Description of the item rotation monitor)
- Check position of jumper according to the
requirements
- Check if control unit signal is effective
- Check connection control signal at the control unit
on contacts 5, 7 and 9 against ground (contacts 3 or 4)
supply voltage of 24 V must exist.
If not: check trip line
