Suitable Properties and Applications
Common Problems
Gate motor not opening, not closing or gate stuck
Power, battery, controller, receiver, limit, safety-device or mechanical resistance faults can produce similar symptoms.
Arrange fault finding rather than forcing the gate or replacing parts without testing.
Gate moving slowly, stopping or behaving intermittently
A weak battery, charging fault, poor power, gate resistance, rack alignment, motor load or control setting may be involved.
Have the gate mechanics, operator load, battery and charging system checked together.
Gate motor beeping or showing a battery warning
The warning may relate to battery condition, charging, mains supply or model-specific status indications.
Record the beep pattern or display message and request an inspection before repeatedly resetting the motor.
Remote, receiver or access-control trigger not operating the gate
Remote batteries, receiver memory, radio interference, wiring, controller inputs or the gate motor itself may be responsible.
Test the controls and operator together so the failed part is identified before replacement.
Gate reverses, stops unexpectedly or ignores an end position
Safety beams, limits, origin sensing, rack alignment, obstruction or gate resistance may affect travel.
Keep the entrance clear and arrange a safety and travel inspection.
Unusual motor, gearbox or gate noise
Worn gate hardware, rack alignment, gearbox condition, motor load or loose mechanical components may contribute.
Stop repeated operation if movement is strained and have both the gate and operator assessed.
Fault after lightning, a surge or power interruption
Power supplies, chargers, controllers, receivers, accessories or cabling can be affected, sometimes in more than one place.
Request controlled testing before replacing a control board or reconnecting accessories.

Repairs and Maintenance
- Fault finding can cover the battery, charger, incoming power, cabling, controller or PCB, receiver and connected accessories.
- Mechanical checks can include the rack, pinion, track, rollers, gate alignment, end stops, motor and gearbox condition.
- Safety beams, limits and origin sensing should be tested when a gate reverses, stops or loses its travel position.
- Intermittent and surge-related faults may affect more than one component and should not be diagnosed from a single symptom.
- Older CENTURION motors can be inspected for repair, servicing or an appropriate replacement path; replacement is not assumed automatically.

FAQs
Why is my gate motor not opening or closing?
The cause could be power, battery, charging, controls, safety devices, limits or gate mechanics. Similar symptoms can come from different faults, so the system should be tested before parts are replaced.
Why is my gate motor beeping?
Beeping can indicate a battery, charging, power or model-specific status condition. Note the pattern and any display message, but avoid treating it as a certain diagnosis without inspection.
Why is my gate moving slowly?
Battery condition, charging performance, gate resistance, rack alignment, motor load and settings can all affect speed. The gate and operator should be checked together.
How do I know if the gate motor battery is failing?
Slow movement, limited operation during outages or battery warnings may justify testing, but charging or mechanical faults can look similar. A battery and charger test is more reliable than symptoms alone.
Can an older CENTURION gate motor be repaired?
Often it can be assessed for repair or servicing. The decision depends on the installed model, fault, gate condition, safety, parts availability and the overall cost of returning it to reliable service.
Should I repair or replace an old gate motor?
Replacement is not automatic. SonSec can inspect the motor, electronics, gate mechanics and safety devices, then explain whether repair, servicing or replacement is the more practical route.
Can a gate motor be damaged by lightning or a power surge?
Yes. Surge damage may affect the controller, charger, receiver, accessories, power supply or cabling. Testing is needed to establish the extent of the damage.
Do you repair CENTURION SMART gate motors?
SonSec provides diagnosis-led repair and service support for supported CENTURION SMART gate motors, subject to site condition, product condition and parts availability.
