If a fault occurs in the drive, the Fault LED on the front panel of the drive will illuminate. The
MPU will reset the drive as long as the RESET / NON RESET switch on the relay board is in
the up, or RESET position.
To access the drive faults, using the hand held programmer, go to the FAULTS F0 menu. This
menu has two sub-menus, ACTIVE FAULTS F1 and FAULT HISTORY F2. Use the arrow keys
to access the desired menu. If the drive is faulted, ACTIVE FAULTS will display the present
fault. FAULT HISTORY will display faults which have occurred.
For a complete list of drive faults, refer to the MagneTek HPV 900 manual.

Note:
The brake assembly and all pins should be cleaned thoroughly and all spring
tensions set properly to hold 125% of car capacity prior to adjusting the brake
driver. Brake shoes should be checked to insure at least 95% surface contact. If
spring tensions are changed after this adjustment, the brake driver will need to be
completely re-adjusted.
Ensure the brake coil has been connected properly to the controller.
