Troubleshooting
LED Display Status
Problem
Suggestion
Buffering mode (Buffering)
• Orange LED display status is flashing
slowly.
1) If there is no output voltage, this means the set
buffering time has expired.
2) Restart the DC-UPS module to reset the buffering
time.
Normal mode (Charging)
• RED LED display status is On
(not flashing).
1) Check the Replace BAT relay contact. If it
is “Open”,
this either means:
- DC-UPS module is over temperature
- Battery module is over temperature (if the Rx/Tx or
battery sensor function is used)
- DC-
UPS module’s output is overload
2) Check the surrounding air temperature for DC-UPS
module or battery module.
3) Check if system is loading over the DC-
UPS module’s
current limit.
