Charger Voltage High. Major Alarm. After a discharge or application of
power, the Charger Voltage High alarm condition is ignored for 60 minutes.
After the 60-minute delay, the Charger Voltage High alarm occurs if the
string voltage value (the sum of all battery voltages in the string) is above
the string voltage limits.
Minor Battery Fault. Minor battery alarms are unfavorable conditions that
usually do not result in the loss of the critical load but could develop into a
major alarm or would prevent the detection of a major alarm condition.
Possible Causes Corrective Action
