Gate does not move, but the
relays “click” when the unit is
activated:

Gate moves a short distance
and stops:

Gate starts closing then stops &
reopens:
!
Check that you are out of programming mode, SET light
must be OFF.
!
Check the battery condition with procedure A: Low
battery voltage condition, later in this section.
!
Check the motor wires.
!
If STATUS light flashes 4 times then the operator is in
Multiple Collision Mode. Remove & reapply all power, or
wait 60 seconds to reset operation. If required, check with
procedure B: False collision detection, later in this
section.
!
If the problem persists, the CP75 main controller might
be faulty.
!
Check the battery condition with procedure A: Low battery
voltage condition, especially if the STATUS light flashes 3
times.
!
Motor wires use for the SLAVE operator are too thin.
!
Check for false collisions with procedure B: False collision
detection, later in this section (STATUS light could also
flash 4 times if the number of detected collisions exceeded
the COLLISION COUNTER feature value).
!
Intermittent IRB trigger. Check that the voltage applied to
the beams are appropriate.
!
Spurious trigger. Remote with same coding operated in
area, or intermittent short due to possible moisture on the
FRX or TRG inputs.
!
If the problem is still not solved, the CP75 main controller
might be faulty.
!
Check collision sensitivity and other causes with procedure
B: False collision detection.

Gate overruns its limits:
Gate opens on its own
Unreliable auto-close
!
!
!
Check for intermittent IRB (IR Beam) triggers. (Check
beam operation, alignment and supply voltage).
Intermittent/spurious signal on FRX or TRG if in CONDO,.
PIRAC or REVERSING modes. (Standard mode would first
stop then reverse)
If the problem is still not solved, the CP75 main controller
might be faulty.
!

!
Check for latched TRG or FRX input. (Respective lights
would be on continuously).
Intermittent fault on TRG or FRX inputs. Look at all joints,
switches, etc. (Underground joints with moisture buildup)
Outside transmitter with the same code. (Typically only
with DIP switch type remotes)
Faulty receiver
Faulty electric fence
If the problem is still not solved, the CP75 main controller
might be faulty.
!
Latching Receiver on TRG, would activate the auto-close
override feature.
For both MASTER and SLAVE motors: (only the faulty gate's
components need to be inspected)
!
Check that the ORIGIN sensor wire harness is securely
plugged into the CP75 (master controller) or CP74A (slave
board), a nd securely into the ORIGIN sensor.
!
Check that the respective ORIGIN sensor is securely
clipped into the housing.
!
Check if the gate origin was accidentally moved, steps 4
to 10 of the electrical setup. If so reset the limits.
!
For SLAVE motor, check the wiring of S1, S2 and S3 for
continuity and short circuits. Look for and correct all loose
connections and signs of corrosion, be sure to solder all
joints.
!
Make sure that the ORIGIN dust cover is closed. (Ants
could give intermittent false triggers).
!
If the problem is not solved, the CP75 main controller might
be faulty.
