Operating Mode/Status Description
Mode/Status
Description
UPS power on
When UPS is powered on, it will enter into this mode for a few seconds for initializing
the CPU and system.
Line Mode
When the input voltage is within acceptable range, and the UPS is turned on (the in
-
verter is running), the UPS will provide pure and stable sine wave AC voltage. The UPS
will also charge the battery in Line mode.
Battery Mode
When the input voltage is out of the acceptable range or a power failure occurs, and
the UPS is turned on (the inverter is running), the UPS will backup power from battery.
Bypass Mode
When input voltage is within acceptable range and bypass is enabled, and the UPS
(inverter) is not turned on or the inverter can’t support the load, the UPS will switch
to battery.
ECO Mode
When the input voltage is within voltage regulation range and “ECO” mode is enabled,
the UPS will bypass voltage to output for energy saving. If the input voltage is out of
the regulation range but it is still within acceptable range of Line mode, the UPS will
transfer to inverter supplying the power to load (similar to Line mode).
Frequency Converter
Mode
When input frequency is within 46 to 64Hz, the UPS can be set with a constant output
frequency (50 Hz or 60 Hz) through the inverter. The UPS will still charge the battery in
this mode. Bypass is disabled in this mode.
Battery Test Mode
When the UPS is in Line mode or Converter mode, and the battery test command is
enabled through LCD or monitoring software, the UPS will start Battery Test. This op
-
eration is used to check the battery status.
Warning Status
If some errors occur in the UPS (but it is still running normally), buzzer will alarm and
warning code will appear in the LCD for trouble shooting.
Fault Mode
When fatal error occurs in the UPS, it will beep continuously and go to fault mode. It
will display fault codes in LCD.
