Re: Hey digital console users don't forget your UPS
I've thought about this a little more since I brought it up last month. I think a possibility might be a time-delay relay between the UPS and the board that's controlled by the sequencer. I'm talking about something like this (which, incidentally, I use for a delay off on my bathroom fan), except that the power handling is borderline for the X32 at 1A, assuming 120VAC mains--on 240VAC you're fine:
DAYTON Relay, Time Delay - Time Delay Relays - 6A859|6A859 - Grainger Industrial Supply
Normal operation: When you turn on the sequencer, it closes the relay, allowing juice to flow from the UPS to the console. When you turn off the sequencer, it sets up a delayed opening on the relay, eventually cutting off power to the board.
Brown/Black-out operation: Assuming that everything's off, then there are no state changes during the outage, just as you'd "expect." Assuming that things are powered on, then the sequencer cuts power to "everything," including the control line to the power-delay relay. The nice thing here, though, is that, because of the delay, the console stays on, powered by the UPS. If it's just a little blip, then the rest of your system comes back up shortly. If it's a prolonged outage, the operator has time to bring the console down gently (or they choose to either ignore it or cross their fingers).
Notes on that particular relay, since the notation on the device leaves something to be desired. According to Grainger, who commissioned the product:
"1: To Load (HOT)
"2: Line (HOT)
"3: Line Neutral
"6 & 7 would need to be shorted to engage (mV control signal) < 6' to 10' from switch... "
On several blogs folks have said they tied #6 to Neutral and #7 to switched HOT... though that may "work", it's not reccomended. If the available control line has voltage (12VDC or mains) on it, you could use it to close a normally open relay that's connected to pins 6 & 7.
