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 test 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. Dur-
ing the manual test the 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
Te s t
Press the test switch and wait for unit
to transfer to emergency mode then
release. Repeat one more time for a total
of two test switch presses and releases.
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
Press the test switch and wait for unit
to transfer to emergency mode then
release. Repeat two more times for a
total of three test switch presses and
releases.
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 Indi-
cator 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 Cur-
rent 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, recommis-
sion the inverter's load level detection (see Commissioning Test).
Continuous Flashing Commissioning Required • Follow instructions above to initiate the commissioning test.
