Alarm Name
Alarm Description
Action to Correct
Abnormal Battery Current
The equalize charging current exceeds the
alarm setting.
Check the alarm setting.
Temperature Compensation Active
Battery charge temperature compensation
is active.
--
Battery Current Limit Active
Battery is in current limit.
--
Bad Battery
Battery test fails.
Check the batteries.
Battery Discharge
Battery is discharging.
A battery test is active (the discharge test
will stop automatically). There is a mains
failure (check that it is not caused by open
AC input circuit breaker). The system load is
higher than rectifier capacity, causing the
batteries to discharge (install additional
rectifiers).
Battery Test Fail
Battery test fails.
Check the batteries.
Comp Temp High2
Compensation temperature sensor sensing
temperature higher than high temperature
threshold 2.
Check why temperature is high or low.
Comp Temp High1
Compensation temperature sensor sensing
temperature higher than high temperature
threshold 1.
Comp Temp Low
Compensation temperature sensor sensing
temperature lower than low temperature
threshold.
Compensation Sensor Fault
Temperature Compensation temperature
sensor failure.
Replace temperature sensor.
System Temp1 High 2
Temperature sensor #1 sensing
temperature higher than high temperature
threshold 2.
Check why temperature is high or low.
System Temp1 High 1
Temperature sensor #1 sensing
temperature higher than high temperature
threshold 1.
System Temp1 Low
Temperature sensor #1 sensing
temperature lower than low temperature
threshold.
System Temp2 High 2
Temperature sensor #2 sensing
temperature higher than high temperature
threshold 2.
Check why temperature is high or low.
System Temp2 High 1
Temperature sensor #2 sensing
temperature higher than high temperature
threshold 1.
System Temp2 Low
Temperature sensor #2 sensing
temperature lower than low temperature
threshold.
