How to Troubleshoot a CP80 D5 or D3 Gate Motor When the Gate Does Not Run But the Relay Energise



When you activate the gate motor via a remote or any trigger device, and the relays energize but the gate does not move, please refer to the possible causes and solutions below:

Possible Causes:

  • Faulty motor circuit
  • Faulty motor relay / FET
  • Motor fuse blown
  • Fuse holder making bad contact
  • Worn motor brushes
  • Loose motor wire
  • Faulty controller

Possible Solutions (On-Site Checks):

  1. Motor Fuse:

    • Confirm that the motor fuse still has continuity.
    • If the fuse is blown, replace it with a 16/20A slow blow (5x20mm).
    • Ensure the fuse is making good contact in the fuse holder.

  2. Motor Wires:

    • Check that the motor wires are securely connected to the PC board.

Further Action:

  • If all the above checks are in order, take the motor to your nearest CENTURION branch for testing and possible repairs.
