PROG INPUT1, PROG INPUT2, PROG INPUT3. These three inputs
can be independently programmed to function as an auto transfer
switch input, single-phase override input, low coolant level input, fuel
leak detection input, battery charger failure input, or an auxiliary
input. The inputs accept normally-open contacts connected between
terminals P2 (PROG INPUT1), P3 (PROG INPUT2), or P4 (PROG
INPUT3) and terminal P21 (BATT –).
