Centurion D5 Evo sliding gate motor issue

[Jonny_9]

I have a Centurion D5 evo sliding gate motor.
It has worked fine for years. Yesterday it kept opening again after closing. I cleaned some dirt from the tracks near where front wheel reached at end of closing movement just in case there was resistance from dirt. It now runs fairly freely by hand.
So that issue is ok.

I thought I should just reset gate limits again. Went to the lcd menu and went through setup wizard to reset limits.
It finds stop 1 (closed position) fine. It finds stop 2 position (open position) fine. And both times that the origin magnet passes the origin sensor I can hear a click and lcd screen at that moment says "origin on left" and "origin on right". So origin message does seem to go through.
As soon as it finished the limit setting process and has found stop 2 (fully open) the screen says "Setup Fail Origin Not Found"

I have tried it about 30 times now. I have run it free hand and engaged motor to start rest procedure from different positions and same result: Origin Not Found. If it says origin not found you just can't use the gate. The origin on gate looks fine and is bolted into position just like it always was.

I unplugged DOSS harness from PC board and immediately LCD screen beeps and says that DOSS not detected. (So I assume pc board is picking up DOSS ok because when I plug it back in the lcd screen is happy).

I have done factory reset. No change.
I have unplugged both battery and mains and replugged them in. No change. Battery voltage is 13.4V and charging voltage is 14.1V.


Anyone know what to do?

It's most likely not counting the distance correctly everytime.

There's a timing gear behind the knob that puts the gate on manual. That compartment does get dirty sometimes and that can clog some of the slots in the timing gear.

Carefully unscrew the knob from the motor. It is spring loaded so keep pressure on while you unscrew it. Once all the screws are removed slowly pull the knob out. There's a spring and bearing in there so make sure you note how it goes together.

Once you remove the knob you'll see a gear with slots on it. This is connected directly to the drive gear that moves the gate. You'll also see the bottom end of the doss sensor. You can unscrew the sensor as well.

Clean the doss sensor and the timing gear wheel with a brush and electronic cleaner or any other cleanser that doesn't leave a residue.

If you see oil in that compartment then the shaft seal is probably leaking. Centurion will only sell the complete gearbox unit. Otherwise you must just clean it when it starts acting up.

You are a star for replying in such detail.

I was hoping I didn't have to remove that cover held behind the turning knob held in place with the 4 allen key screws. Cos my screws are rusted soft (at coast) Will work out something to get it off. Damn. I'll let u know. Thanks again.

You welcome

I think they torque screws iirc.

You could also try removing the doss sensor and then spraying the cleaner via that hole while someone moves the gate.

Just make sure that the sensor is dry before trying to set limits again

Looks ok? Some dust or stuff at bottom on chamber, but slotted wheel looks clean to me. Not sure how.itnis supposed to look. Didnt feel oily to me.
Maybe it's the doss counter thing giving the issues? Also seemed clean to me.
Not sure if they must be microscopically clean? But they looked ok.

(Managed to unscrew top two screws. Bottom two unsuccessful so ground heads off. Will replace them when i have this motor fixed.)

I reassembled everything and giving same "Origin not found" message with limit setup. :-(

Try with a different Battery, Centurions are very fussy when it comes to batteries, especially under load. then the second option is the origin sensor, wipe it off, sometimes there is friction between it and the outer housing of the motor and dust bults up. The sensor can also be going.

Check the battery voltage while the motor is running, with a meter.
Do a master reset, basily long press that big knob.
is the gear turning all the time while the gate moves, no broken off teeth or it lifted.

Ja, I thought of that. Yes the gear is turning all the time. There is one small hiccup on teeth track where an additional piece was added in the past. Far away from magnet origin. But motor has never had a problem with that in the past. But no new issues like broken teeth. Nothing lifted. Gear in contact all the time.

Ok, I'll try master reset. (I did the fzctory reset, the milder reset where it doesn't forget remotes, but notnthe deeper reset. At this stage reprogramming remotes is least of my concerns)

Will also check battery terminals tomorrow under load (will check while motor is doing its limit settings test that it fails cos thats only way i can get it to run at this stage)

Would sensor be going if it still clicks when origin moves past it? Perhaps it could send dodgy/incoherent signals to pc board if it were going downhill.

did do open your pc board and look for ants that made a nest under track.

Two weeks ago, busy with a gate, I notice the amps were very high, motor went.
