MAINTENANCE & TROUBLESHOOTING
Always turn off SW-1(first), then turn off AC power to the equipment inside the case before
servicing.
Servicing should be performed only by qualified service technicians. Use only manufacturer supplied
replacement parts. Although no routine maintenance is required to keep this emergency lighting inverter
functional, it should be checked periodically to ensure that it is working.
1. Automatic self-testing performs a 30-second test once every month and a 90 minute or 120-minute test (depending on
model) once per year. A failure during this test will cause the charge indicator LED to flash with a code indicating the
failure type.
2. Visually inspect the charging indicator light monthly. It should be steadily illuminated. If flashing, use the table below
to determine the failure mode and follow the troubleshooting steps.
If manual testing is desired, the illuminated test switch on the product cover can be used to send the product into three
different test modes. These modes are detailed in the table below.
TESTING
WARNING:
Test Type
Procedure to Follow
Description
Manual Test
Press and Hold the Test Switch
Initiates the emergency mode for as long as the switch is depressed. During the manual
test t
he emergency lighting load will turn off momentarily (if switched power is present).
After a few seconds, the lights will turn back on in the emergency mode. Releasing the
test switch will return the emergency lighting load to the normal AC mode.
Manual 30-Second Test
Press and Release the Test Switch
Two Times
Manually initiates a 30-second diagnostic test. The inverter will switch to the emergency
mode for 30 seconds and test all relevant functions. Once complete, the inverter returns
to normal AC mode and indicate any faults, if detected.
Commissioning Test
Press and Release the Test Switch
Three Times
Initiates a 30-second commissioning test. The inverter will switch to the emergency
mode and store in its memory the current connected load level. If, during future self-
tests, this load level deviates by more than 10%, an error will be triggered.
TEST SWITCH MODES
Trouble State or Indica-
tor Light Status
Error
Corrective Action
Indicator Light On Steady
None
•
No Action. The product is operating correctly.
Indicator Light Off
No Unswitched AC Mains Present
•
Unit maybe operating in emergency mode only and there is no error
•
Check unswitched hot wiring connections.
•
Ensure unswitched hot circuit breaker is on.
•
Ensure switch SW-1 is on.
1x Flashes
Load Control (Transfer) Fault
•
Check output voltage if it is within the spec
•
Check if output load is connected properly
•
Check output voltage is functioning
•
If all the above conditions check OK, replace unit.
2x Flashes
Battery Fault
•
Charge battery. If after an hour failure is still indicated, see battery action below.
3x Flashes
Battery Disconnected or Charge Current Fault
•
Ensure input wiring is correct and verify voltage is correct and stable.
•
Check battery voltage and ensure battery is connect fully.
4x Flashes
Load Level Change Greater Than 10%
•
Ensure proper operation of all connected loads. If all functional, recommission the
inverter's load level detection (see Commissioning Test).
Continuous Flashing
Commissioning Required
•
Follow instructions above to initiate the commissioning test.
