RCD trip on close LUX 2B

[JoeF]

Hi, I have a single LUX 2B running on a Rigel 5 controller. Recently started having issues with it tripping the RCD when on a gate closing cycle. I've replaced the RCD with no luck, motor capacitor has been tested and is all gd. Photocells have been inspected, one did have water ingress, I haven't tested with the photocells disconnected. Starting to think the motor has gone bad, is there anything else I can test/try? 

Cheers

Hi Dave,

thanks for the message,

this to me sounds like it is either a short on the closing phase of the motor cable or a short on the motor windings which intern could have been caused via water ingress, have you checked the cable at all?

Thanks 
Joe
