My AM12AU switches on/off erratically, I'm using a ban pass filter at the controller and also at the main meter board. Having done some investigation, this seems to be a common problem with some of the USA units (AM466 and PSC02) were information is available to disable this problem. Unfortunately the printed circuit board inside the AM12AU does not match the USA units. Any suggestion or links would be appreciated.

erratic?
Do they miss commands or do they go back on when turned off.
What type of loads are on them?
If they are misssing commands it could be a signal problem.
If they go back on when turned off. It could be a Local Control problem.
Anymore information you can give may help in getting your problem fixed.
