POSSIBLE CAUSES & SOLUTIONS TO PROBLEM
To determine which is the faulty gate in a double swing system,
activate the gates. Both gates will stop and reverse on closing,
but only the faulty gate will stop when opening.
For both MASTER and SLAVE motors:
(Only the offending gate's components need to be inspected)
Check for tight hinges, unbalanced gate, or something
physically obstructing the gate. Activate the manual
override and move the gates to check for ease of operation.
For SLAVE motor, check the wiring of S1, S2, S3 and the 2
motor wires for continuity and short circuits. Look for
moisture on any joints and correct all loose connections
and signs of corrosion. (Joints should be soldered together
to ensure a reliable joint.)
Check for ants and dirt in and around the DOSS sensor.
Check the DC motor wires for loose connections.
Check contact of the fuses with the fuse holder on CP75
(main controller).
Check that the sensor wire harness is securely plugged
into the CP75 (master controller) or CP75A (slave board)
and into the DOSS sensor.
Check that the DOSS sensor is securely clipped into the
housing.
If the problem is not solved replace the DOSS sensor
(CP75B), then the Slave card (CP75A), and main controller
(CP75).
