I've been away from here for a while and I've lost my EXPERT distinction. Still don't know if I'm returning actively or not. I still get emailed on previous threads. Some of the reasons I left were fixed, some not.
If only certain devices are a problem. On page 6 here: http://literature.rockwellautomation...d001_-en-p.pdf there is a schematic of a start/stop ckt. If you ignore the STOP and the O/L and make the Motor an outlet, you can put this circuit in an outlet strip or separate box with a power light. When the power drops out for about 20 mS or so, the outlet strip will stay off until reset. It requires a DPDT r120 VAC coil relay, a normally open push button and a pilot light if not present.
I would do this for devices with problems. I have placed this circuit in an outlet strip. I attached it to an auto answer modem. If I called a number and it didn't answer, we had a power failure.
