Thought about it, but I need a little bit more logic. Tried to find a
240 voltage monitoring relay with some time delay functions. They exist
in SPST, but I need DPDT. Could I use an SPST to trigger the existing
transfer relay (12vDC coil), yes. But then I need an additional power
supply that's battery backed. I'm trying to control a stand-alone
Generac RTG switch. All of the monitoring and transfer decisions would
be happening outside in the generator controller (it monitors both
utility legs and starts its timers and sequences when it sees 192 volts
or less), but obviously I'm not going to have that.
Basically I'm going to stack this switch onto the service transfer
switch that the generator will be managing. So I'm thinking for now I'll
just pull the 12v transfer signal over which will transfer both switches
at the same time. That's all fine and good... if the service is out on
the generator side. If we lose utility on the other side (where the
second switch will reside), but not on the generator side, then it won't
transfer and I'll be screwed.

Subject: [AFMUG] PacketFlux stand-by controller
Can the PacketFlux controller's mains monitor transformers take both
120v legs (4 total to monitor) or do I need to put in two external
240>120 step-downs?
