LV1/BOD
PB input low voltage (below 53 +/- 0.5) /system battery on discharge alarm (PB input voltage
below 53 +/- 0.5). (ie. the DC plant Voltage is low) Increase in voltage clears the alarm.
LV2/VLV/SDP
PB input very low voltage alarm (below 46V +/-0.5). (ie. the DC plant Voltage is low) Increase
in voltage clears the alarm.
HV1/HFV/HVSD
This alarm is the result of an input voltage being above the high voltage set point (55.50 +/-
0.5). Check the DC plant voltage.
