Troubleshooting
The following sections list troubleshooting procedures.
Drive Fault / Encoder Fault
The most common fault at startup with a Magnetek drive is the Encoder fault.
Perform the following checks to correct this fault:
Check for a solid shield-to-ground connection at the motor and drive.
Check for correct colored encoder wires to the terminals.
Swap A+ / A- on terminal TB1 – #1 (A+) and #2 (A-).
• After swapping the A signal wires it may be necessary to change the direction of the
C1 – Encoder Connect.
Brake Not Lifting
If the brake is not picking, make sure that the brake is wired according to C4 Controller sheet 05
Brake Connection and if there is a second brake installed, verify that the EB terminal is
jumpered to the terminal. See the C4 Controller sheet 01 – Getting Started for more
information.
If the brake has the proper voltage check the following:
During a run command, check the DC voltage between points K1 / K2 and J1 / J2 if
secondary brake is installed. Verify the voltages are also at the brake coil(s) when
commanded to pick.
Verify that the actual brake voltage matches the brake coil voltage shown on the C4
Controller sheet 01 – Getting Started Parameter table.
Wrong Direction
If the car is moving in the wrong direction check the following:
On the Smartrise controller board make sure that IO CUP comes on when commanding
the UP direction and IO CDN comes on when commanding the DOWN direction.
Swap two of the motor leads (T1 with T2).
