Centurion gate and garage motor repairs and installation

• Sliding gate motors: the D-series, from the D2 Turbo and the D5-Evo to the D3, D5 and D6 SMART and the D10. Control cards, gearboxes, chargers, batteries, limits and racks.
• Swing gate motors: the Vantage, Vector2 and the R3 and R5 arms.
• Garage door motors: the SDO4 for sectional and tip-up doors and the RDO for roll-up doors.
• Access: NOVA remotes and receivers, SMARTGUARD keypads, Photon beams and the G-SPEAK ULTRA GSM intercom.

All our spare parts are genuine, and every repair carries our six-month guarantee on our repairs. Repairs Plus is an independent installer and repairer. We are not the manufacturer.

A Centurion D5-Evo or D10 says a lot through its status light, on the controller or on an indicator wired to your intercom. Centurion's user guide gives these signals:

Battery low. When the battery drops below 10.5 V on a D5-Evo, or 21 V on a D10, Centurion's Battery Low Protection lets the gate finish its cycle, closes it and shuts the motor down until the battery recovers. If the mains is on and it keeps happening, the battery is usually worn out. Centurion says its maintenance-free batteries should give at least three years; we test and replace them, see gate motor batteries.

Collisions. Four flashes almost always point at the gate rather than the motor: wheels or guide rollers that don't turn freely, a track full of stones, or a rack pressing down on the pinion.

No mains. Check the breaker or isolator that feeds the motor. A fault on the supply itself is a job for a registered electrician.

After a storm. Lightning and power surges kill control cards. Centurion builds in lightning protection but says it only works with a proper earth, and the manufacturer's warranty doesn't cover lightning damage, so a storm-damaged card has to be repaired or replaced.

Each model's full fault table is on its manual page: start with the D5-Evo fault finding page.

Centurion's user guide gives owners a short maintenance list. Most of the faults above start where it isn't followed:

1. Keep the track clear of stones, dirt and anything else in the way.
2. Make sure every roller turns freely.
3. Put the motor on manual and push the gate along its rail: it shouldn't catch on walls or pillars.
4. Check the wheels and guide rollers for wear; on a busy gate they need replacing regularly.
5. Check that the rack is fixed firmly and doesn't press down on the motor's pinion anywhere along the gate.
6. Cut back plants around the motor and the rack.
7. Make sure the key still turns the camlock, with a little lubricant if it's stiff.
8. Keep insects and dust out of the motor housing.

How to put the motor on manual is on the Centurion manual page. Anything inside the controller is our job.

Centurion makes two families of garage door motor, and they suit different doors:

• SDO4 and SDO4 SMART: rail-mounted motors for sectional and tip-up doors. See the Centurion SDO4 manual.
• RDO and RDO Digital: motors for roll-up doors, fitted at the door's drum. See the Centurion RDO manual and coding RDO remotes.

Both have a manual release for power cuts, and both depend on a door that is balanced and runs freely by hand. A garage motor that strains, stops part-way or reverses is often telling you about the door, its springs or its tracks, which we repair too: see garage door repairs.

Centurion's NOVA remotes are coded into a NOVA receiver, either on the motor's control card or in a separate multichannel receiver. We code new remotes, delete lost ones and replace receivers; the steps are on Centurion remote programming.

SMARTGUARD keypads, wired or the wireless SMARTGUARDair, open the gate with a code for visitors, staff and family without remotes: see the SMARTGUARD keypad page. For a gate intercom, Centurion's G-SPEAK ULTRA is a GSM unit, which we install and repair along with the other intercom brands on intercoms.
