NOTE:
Major Alarms
Active Alarm Probable Cause of Alarm Corrective Action
SELF TEST STATUS
Output voltage failed or batteries less than 1.85V/cell
during Selt Test.
1. CHECK BATTERIES
2. CHECK INVERTER
Refer to Notes below for additional information.
INVERTER STATUS
Predicted overall health of the inverter calculated by the
power supply’s proprietary algorithm.
1. CHECK INVERTER
2. REPLACE INVERTER
OUTPUT OVERLOAD The output is overloaded or shorted.
1. REMOVE SHORT CIRCUIT
2. REDUCE OUTPUT LOAD
3. REPLACE POWR SPLY
OUTPUT 1 TRIPPED
Output 1 PIM hardware protection mode engaged and
is overloaded.
1. REDUCE OUTPUT LOAD
2. CHECK PIM SETTINGS
CHARGER FAILURE
Charger has failed or shutdown, possible battery over-
temperature.
1. RESEAT INVERTER
2. PERFORM SELF TEST
3. REPLACE INVERTER
INVERTER TEMP
Inverter heat sink has exceeded set temperature (Stand-
by operations suspended until temp drops to safe level).
1. CHECK VENTILATION
2. REPLACE INVERTER
CONFIG ERROR
The power supply is improperly configured and opera-
tion is suspended until error is corrected.
1. CHECK INVERTER MODULE
BATTERY STATUS
Predicted overall health of the batteries calculated by
the power supply’s proprietary algorithm.
1. CHECK BATTERIES
2. REPLACE BATTERIES
LOW BATT WARNING Batteries dropped below 1.85 V/cell.
1. SHUTDOWN IMMINENT
2. CHECK AC INPUT
3. CONNECT GENERATOR
HIGH BATT WARNING Batteries raised above 2.50 V/cell.
1. CHECK CHGR SETTINGS
2. REPLACE INVERTER
BATT DELTA MHO’S VERY
LOW
Conductance delta major alarm threshold has been
exceeded.
1. CHECK ALARM THRESH
2. REPLACE BATTERY
OUTPUT FAIL Power Supply output has failed.
1. CHECK OUTPUT TYPE
2. OUTPUT OVERLOADED?
3. CHECK INVERTER
LINE ISOLATION
AC plug is connected to the inverter. The potential for
backfeed exists.
1. REPLACE POWER SUPPLY
