WDGALRM Winding Temperature Alarm. WDGALRM asserts if any healthy winding RTD
temperature exceeds its alarm setpoint, or biased alarm setpoint.
44
WDGTRIP Winding Temperature trip. WDGTRIP asserts when one or two (when EWDGV = Y)
healthy winding RTD temperatures exceed their trip or biased trip (when RTDBIAS = Y)
setpoints.
