CAME electirc gates, one has stopped working

Scruff

One of my CAME electric gates has stopped working. Checked the motor and it looks like there is no power getting to it.
Its a Z4A control board with what i think is the FROG series gates. I've just downloaded the instructions from here:
http://www.cameuk.com/camenew/tech-docs/02_Control%20panels/ZA4_319S15/s15%20v4-1.pdf

Wont have a chance to try an diagnose the issue on the board until at least tomorrow but would be grateful for any pointers! Only have a voltmeter, nothing fancy.

First thing to do is verify there is power going to the unit.
Then check the fuses on the board.

got a quick look at it and power and fuses are fine.
There is some dodgy wiring though, both gates are wired to the same 3 terminals and not separate ones (with 1 common) as in the instructions. So in addition to all power over the 1 set of connections, only 1 of the 2 "start up" capacitors is being used to drive the 2 gates. Might have something to do with it. Will have to retest the power at the motor tomorrow...

You will need to check the cable as well as the power at the motor. Could be an issue with the cable if everything else is ok.

Each motor has to have a capacitor, the second capacitor may very well be within a junction box at the furthest motor from the controller.

Just curious, which motor is not working? Is it the one furthest from the controller?

I wonder could you please take a picture of those connections and post it up here please, I am very curious as to how it was done.

See attached. Capacitors top right, motor connectors highlighted in red on the bottom. Both motors wired to the UVW terminals but from my reading of documentation the the first should be wired to UVW and the second to WXY.

Its the furthest motor that isnt working.

will do, havent had a chance to do it yet.

Thank you for that, as the saying goes a picture tells a thousand words.
The state of that tells a lot.
You are correct the motors are wired incorrectly I also note that the motors are not earthed via the control board and that the earth from the mains cable is not attached to anything.
In my professional opinion this is dangerous, are those motors earthed another way?
I am trying to work out the logic as to why someone would wire the motors together like that.
I would encourage you to get at least a registered electrician to look at your system there with regard to electrical safety.
Then wire it up according to the way it should be.
