Hello,
I currently have an APC ATS connected in my coloc rack. I'm only using Source A connected to the power supplied to my Rack and Source B is not connected at all. I'm only using the ATS for it's amperage in use display. In my current rack, I have 2 PDUs each with's own display but both of the PDUs are connected to the ATS. That way I have a free plug in my rack so that I can easily plug in my laptop or the crash cart display without adding a power bar and my PDUs are full also. So from time to time, I get a notification of the following :
Automatic Transfer Switch: Phase Leds/Push-button hardware initialized.
Automatic Transfer Switch: 7-Segment display hardware initialized.
Automatic Transfer Switch: ATS Communication established.
My PDUs seems to have stayed up during those error events which in total last 6 seconds because...
