• Press the scroll up key to execute special functions. The functions include buzzer ON (as in figure Q1),
buzzer OFF (as in figure Q2, Alarm silence for UPS Warning), and self-test OFF (as in figure R). The UPS will
execute the battery test for ten seconds. If the self-test is successful it will display figure E1; otherwise, it
will display figure E2 and an error message at the same time.)
Changing the UPS Default Settings
• Make sure the UPS is not “On”. Press the On
and scroll down
keys simultaneously for approximately
three seconds. The buzzer will sound twice, and the LCD will display figure Q1, indicating that the UPS is
in setting mode.
• Except for Buzzer (figures Q1 and Q2) and Self-test (figure R) all of the other default settings may be
changed by pressing the scroll up
key.
• Figure S indicates the bypass input acceptable window. It can be 184-260 VAC or 195-260 VAC.
• Figure T indicates the bypass frequency window of the Inverter Output. The acceptable setting values are
±3 Hz and ±1 Hz.
• Figure U indicates the acceptable Inverter Output Voltage. Possible values are 200, 208, 220, 230, or 240
VAC.
The inverter output voltage needs to match the input voltage for this system.
• Figure V indicates the operation modes of the UPS. Possible values are Online, Eco (Economy) mode, fixed
50 Hz Output, and fixed 60 Hz Output.
• Figure W indicates the adjustment of the Inverter Output voltage, which may be set to 0%, +1%, -1%, +2%,
-2%, +3%, or -3%.
• Figure X indicates the position of the UPS when the UPS is in Parallel mode. Possible positions are 1, 2, 3,
and 4. The position must be 1 if the UPS is not in Parallel mode.
• Figure Y indicates the parallel function status. “P 01” indicates that the parallel function is disabled, and “P
02” indicates that the parallel function is enabled.
• After changing settings you must scroll to the “SAVE” screen (figure Z) and then press the enter
key to
save all of your changes. Then the LCD will display figure AA to indicate completion of the setting changes.
To cancel your changes rather than save them press and hold the “OFF” key for five seconds. The LCD
displays figure AA directly, which indicates that your changes were canceled.
