391 not responsive

[JoeF]

Hi, I have a FAAC 391 swing gate opener set, which has the E0245 board. All's been fine for months, but the other day the gates spontaneously opened, then after that won't close with the key switch, fobs or keypad.

I removed the radio module in case it was receiving spurious radio signals from the fobs or keypad, no change - the key switch - which is across Open A, does nothing. I've tried shorting the switch pins out on the board in case its a switch/wiring issue - no change.

I did a factory reset, ran the auto setup which worked fine, then set the logic to EP, all looks OK, but still no response from either OPEN A or OPEN B pins.

Any ideas please?

Thanks

HI,
this to me sounds to be a short on your command inputs such as your keyswitch as obviously what has happened is that the cables have deteriorated over time causing an open command to be ever present.

to diagnose this disconnect these from all of the inputs in the board and give it a try!
