Active Alarm or
Abnormal Condition
Probable Causes Corrective Action
Output Overvoltage
Reading
Configuration error
Failure of metering circuit on
Power Distribution Board
Failure of Transformer
1. Check output voltage and compare to display
reading:
2. Check the configuration switch settings on the
Power Distribution Board match those required
for the power supply.
3. Check that configuration settings on display
(press UP and Enter simultaneously) match the
configuration switch settings on the Power Distri-
bution Board.
4. Check Output Taps from Transformer.
5. Change inverter module
6. Replace power supply
Line Isolation
Alarm
Failure of input relay
1. Open the Battery Circuit Breaker
2. Pull out and re-seat Inverter Module
3. Turn the Battery Circuit Breaker back on.
4. Run Self Test (press Down and Enter
simultaneously).
5. If Alarm…..Replace power supply
Output Failure
Alarm
Battery End of Discharge
during Line Input Fail
Configuration Settings incor-
rect
Output overloaded
Output in short circuit
1. Check for AC Input Voltage present
2. Check Output current on the display. If Output
Current is > 100% of rating, correct overload
conditions.
3. Measure the output voltage and compare to the
display output voltage
4. Check Output Taps from Transformer.
5. Check the configuration switch settings on the
Power Distribution Board match those required
for the power supply.
6. Check that configuration settings on display
(press UP and Enter simultaneously) match the
configuration switch settings on the Power Distri-
bution Board.
7. Open the Battery Circuit Breaker and
8. Pull out and re-seat Inverter Module
9. Turn the Battery Circuit Breaker back on.
10. Replace power supply
Battery Temp Probe
Alarm
Temperature Sensor Failure or
Inverter Board Failure
1. Inspect RTS sensor, wire and connector to see if
there is an intermittent connection
2. Replace with known good sensor
3. Check Battery Temperature Display Reading
4. Check for Alarm
5. Replace Inverter Module
