For 2001 DC Non-Solar mode
AC
(Power)
AC Power and External AC power (not looking at 48VDC)
Battery
>12.3v (DC-DC)AND >41.6 (48V battery) (either 12 or 48 fail will
cause a fail)
Transfer switch low voltage detect (External AC input Sense2,
low=voltage pass)

Jumper pins 9 and 10 for Kenwood/TR Monitor and Control mode
When the Kenwood mode is polled, the unit responds over the port which received
the poll request only.
TR monitor and Control mode
For FCD2001 or FCD Eclipse types, relay #3 is used for TR Control and Remote AC
power Sense is used to monitor TR voltage.
Remote AC power Sense debounce fixed at 4 seconds (normally 28 Sec).
Standby:
 If low voltage is detected close relay #3
 If low voltage is not detected open relay #3
Running a function:
 If low voltage is detected relay #3 closes for duration of function.
 If voltage changes to good while running a function relay remains closed for
duration of function
If unit is not a FCD2001 or FCD Eclipse or JP11-9,10 is not asserted relay #3
functions as programmed.
