Good evening,
Since mid-2021 we live in a property with a Came ZA4 electric gate, which seems to be very prone to failing.
After it had died for the 3rd/4th time in less than a year, I called the original installers, who said that they would not come out to investigate, as the previous owners did not want to take their advice of sorting out the dodgy wiring, and that they had been out to diagnose more times than they care to remember. So that avenue is a dead-end. If the wiring was the issue, surely the RCD in the garage should be tripping.
I've had the outer box off and had a look, but couldn't see anything odd. An electrickery-savvy friend had a look, scraped a bit of residue off the connectors on the circuit board, and the gates worked again. When they failed again, he came round again, and said that the summer heat had caused a cable to short out, he replaced it, and all was well again (not sure I buy that... we're in the UK!).
Lo and behold, this week the gates failed again.
I took the cover off, and cleaned around the board and checked the wiring. All looked OK. The little red LED was not lit.
I checked the fuses, and noticed that the top 1A fuse was short-circuited. The other two (5A) were fine. I removed the 1A fuse, and fiddled with the wiring around the transformer.
Still nothing.
I shorted the fuse (I know, I know), turned on the power, and noticed the transformer getting really hot. So if I fit a fuse, it's likely to pop - for a good reason.
Any ideas where I can start looking? Is the board borked, and have I messed up the transformer?
I'm tempted to ask a qualified person to come round and give proper advice, but thought I'd pick the collective's brain first.
Thank you.
