POSSIBLE CAUSES & SOLUTIONS TO PROBLEM
Long pulse on TRG would activate the auto-close override
feature.
Faulty IR Beam input.
Intermittent power loss, check for low voltages with
procedure A: Low battery voltage condition.
If the problem is still not solved, the CP75 main controller
might be faulty.
Intermittent fault on PED (pedestrian) input. Check wiring,
and key switch operation.
B: False collision detection.
If the problem is still not solved, the CP75 main controller
might be faulty.
By default the motor would delay opening to pedestrian for
2 seconds. This time can be changed or removed by
changing the value of the PREFLASH TIME feature (Feature
11)
There is a continuous PED signal, the PED light will be on
continuously. (The PED light & signal must turn on
momentarily for the gate to close after a pedestrian signal.)
Check for latching Receiver, or a faulty key switch.
If the problem is still not solved, the CP75 main controller
might be faulty.
The slave motor wires are too thin.
Either of the Master or Slave motors were not installed on
the recommended positions.
The fault is with the receiver.
Check the wiring between the receiver and control card.
Check that the receiver has power. If not, check the 3A
Auxiliary fuse on the main controller. (NB. remove fuse
before measuring.)
The receiver could be faulty.
