AP7721: Automatic Transfer Switch: Phase Leds/Push-buton hardware failure.

[andrewlavens]

Hello all. Following a power failure, the AP7721 now reports 'Automatic Transfer Switch: Phase Leds/Push-buton hardware failure.' This is followed by 'Automatic Transfer Switch: Phase Leds/Push-buton hardware initialized.' This pair of messages repeats every few seconds.

Less often, but still repeating, are the messages 'Automatic Transfer Switch: 7-Segment display hardware failure.' and 'Automatic Transfer Switch: 7-Segment display hardware initialized.'

I've also noticed that the display briefly shows 'Er' (for a fraction of a second) and this too repeats every few seconds, presumably matching the log entries.

Is this a failing unit or are there a few things I could do to recover it?

(P.S. I know about the spelling changes. If I spell 'buton' correctly I get a warning 'The message subject contains bu*t, which is not permitted in this community.')
