This is a basic checklist for your gate automation system. Should you experience a fault with the system, see if the symptom corresponds to any given in the list below. For each symptom listed, the probable cause and action to be taken is given. In the event of the symptom not being listed, consult your installer for assistance.
CAUTION
PRIOR TO WORKING INSIDE THE CONTROL CARD ENCLOSURE, ENSURE
THAT THE MAINS SUPPLY TO THE SYSTEM HAS BEEN ISOLATED.
NB: As this product is used outside of the control of the manufacturer, CENTURION SYSTEMS
(PTY) LTD, it cannot be held responsible for consequential damage as a result of the end user attempting to maintain the unit without the assistance of a qualified installer.
SYMPTOM
Gate does not open or close fully or gate moves a short distance and stops.
CAUSE
There is an object obstructing the movement of the gate.
Anti-crushing device setting is too sensitive
Position control system is malfunctioning.
ACTION
INDICATION: STATUS LED will be flashing 4 times per 2 seconds.
Clear any obstructions from the gate.
Unhook the gate from the m e c h a n i c a l l i n k a g e a n d check that the motor operates c o r r e c t l y. C o n s u l t y o u r installer should there still be a problem.
C h e c k t h a t t h e s e n s o r m o u n t e d a d j a c e n t t h e geared DC motor is clipped into position. Check both
MASTER and SLAVE motors where applicable.
Battery voltage is low and the battery protection is being activated.
INDICATION: STATUS LED will be flashing 3 times per 2 seconds.
Check that the battery is charging.
Check that the mains supply is connected and switched on.
Touch the side of the charger unit, it should be hot if the battery is charging.
Check battery connections are tight and that there is no

corrosion.
When was the battery last changed?

The life span of the 7A/H maintenance free battery supplied with the system is typically up to three years.
Gate does not operate but the relays on the controller
"click" momentarily.
Motor fuse blown on the control card.
Battery voltage is low.
Gate lock not releasing
(applies to typically single gate installations where a solenoid or magnetic lock has been fitted).
Replace blown fuses R3-

Make sure that the motor fuse holders are making good contact.
See action earlier in this troubleshooting guide for
battery voltage is low and the battery low protection is being activated.
Solenoid lock: check that the lock is trying to release. it will make a distinctive "click" sound when energised. Then check that the lock is not being mechanically held due to misalignment, dirt etc.
Magnetic lock: Pull on the lock when activating the gate to release and feel whenever the lock is releasing. Try d i s c o n n e c t i n g t h e l o c k
( r e m o v e t h e w i r e f r o m terminal 13)
Consult your installer if the problem persists.
Gate does not operate and there is no reaction from the motor relays either. Only the radio receiver relay "clicks" when the system is activated.
An input is latching up the controller.
Check that both the GREEN
IRB (infra red beam) and LCK
(holiday lockout) LED's on the CP75 controller are ON.
Check that the other RED

SYMPTOM
Gate does not auto-close.
CAUSE ACTION
input LED's are OFF. They must only light up when the c o r r e s p o n d i n g i n p u t i s activated.
Try operating the system using the TEST pushbutton on the control card.
Consult your installer if the problem persists
Infra red beam (if fitted) is faulty.
Check that the auto-close override facility is not being operated.
Check that the GREEN LED adjacent the IRB input is ON
When the IRB input is ON
Then the infra red beam is clear.
Check that beam is correctly aligned. It should be possible to hear the relay "click" as the beam is broken and cleared.
E n s u r e t h a t n o b o d y i s mistakenly pressing and h o l d i n g d o w n t h e g a t e release pushbutton on either the remote or intercom for too long when activating the unit. Refer to section Auto-
close override.
Gate starts closing but stops and re-opens.
Intermittent operation of infra red beam if fitted.
Anti-crushing device is set too sensitively.
Check the GREEN IRB LED on the controller. It must remain ON if the beam is clear.
Consult your installer if the problem persists.
Unhook the gate from the mechanical linkage and check that the operator then drives fully closed. Consult your installer if the problem persists.
Operator drives too far and does not stop in the correct open and closed positions.
Origin system not functioning correctly.
Check that the origin sensor which is mounted on the black plastic housing which covers the manual override, i s p r o p e r l y c l i p p e d i n .

SYMPTOM
Gate opens on its own.
Radio transmitter has poor range.
Permanent input on one of t h e t r i g g e r l i n e s t o t h e controller.
CAUSE
Origin position has been shifted.
Faulty trigger line cables.
Transmitter battery flat.
R a d i o r e c e i v e r c a n n o t receive transmitter signal properly.
ACTION
Consult your installer if the problem persists.
Make sure that nobody has accidently used the origin adjustment tool to release the manual override. Consult your installer should this be suspected.
Check that the RED LED's adjacent each trigger input on the controller (TRG, FRX,
PED) are OFF and only switch ON when that input is activated.
Consult your installer.
Check that the fault only o c c u r s w i t h o n e o f t h e transmitters. Replace the battery.
Receiver must be mounted in an elevated position, housed i n a w e a t h e r p r o o f, n o n ferrous enclosure.
Make sure that the aerial is straight.
Consult your installer.
Master gate opens to pedestrian and closes.
Courtesy light does not operate.
K e y - s w i t c h u s e d f o r activating pedestrian facility is faulty - where applicable.
Light fuse blown.
Check for corrosion of the wire terminations behind the key-switch. Consult your installer should the problem persist.
Replace fuse - 220V 3A fast blow. Size 5x20mm.
CAUTION - 220V, make sure supply to system is isolated
Check that the lamp load does not exceed 500W.
Check the bulb and replace if necessary. Make sure that the bulb is making good electrical contact in its holder.
Consult your installer should the problem persist.
