Reserved RW UI16
48076
16th annunciation enable for Relay 2 – Reserved for future C12 data RW UI16
48077
Output for Relay 2: 0 = contact open / 1 = contact closed R UI16
48078
Relay 2 annunciation type: 0 = momentary / 1 = maintained / 2 =
latched
RW UI16
48079
Relay 2 contact sense: 0 = closed for normal operation, open for
annunciation; 1 = open for normal operation, closed for annunciation
RW UI16
48080
Relay 2 output duration for momentary type, adjustable from 2 to 100
in unity increments (which is 0.1 to 5 seconds in 0.05 second
increments)

b0 = field overvoltage, b1 = field overcurrent, b2 = gen. Undervoltage,
b3 = gen overvoltage, b4 = underfrequency, b5 = in OEL, b6 = in
UEL, b7 = in FCR mode, b8 = loss of sensing voltage, b9 = setpoint
at lower limit, b10 = setpoint at upper limit, b11 = unassigned, b12 =
gen. Below 10 Hz, b13 = field overtemperature, b14-b15 are
unassigned.
