7. Setting by LCD Module
The output voltage and frequency, and bypass state, and ECO mode, and
Converter mode could be set directly thro ugh LCD module. The output
voltage could be set to 208V, 220V, 230V and 240V. The output frequency
could be set to 50Hz and 60Hz. The operating mode of UPS could be set
between the Line mode, ECO mode and Converter mode. The bypass
state could be set to enable and disable. But all the settings could only be
done when the UPS is in bypass or no output mode.
In bypass or no output mode, pressing the “Select” button on the LCD
panel for more than one second, a flickering black dot would be shown
before “208V” on the screen. And if pressing the “Select” button
continuously again, the flickering black dot would move to “220V”, next to
“230V”, “240V”, “50Hz”, “60Hz”, “Bypass Disable”, “Bypass Enable”,
“UPS”, “ECO”, “CVF” in turn. (Here “UPS” means the normal inverter
mode, and “UPS”, “ECO”, and “CVF” would be presented circularly at the
position of output voltage) And if pressing the “Enter” button for more than
one second at this time, the flickering black dot would turn to flickerless
and the output voltage or frequency or bypass state or mode state setting
would be modified to the selected value. And if no any pressing on the
“Select” or “Enter” button lasting for more than 30 seconds, the flickering
black dot would disappear.
The only one voltage value could be selected in “208V”, “220V”, “230V”,
“240V” at any time. The only one frequency value could be selected in
“50Hz”, “60Hz” at any time. And the output voltage and frequency would
be changed to the corresponding value after the right values are selected
on the LCD panel and the UPS is turn on by pressing the “ON” Button.
The UPS would turn to bypass mode in several seconds after “Bypass
Enable” is selected, and turn to no output mode in several seconds after
“Bypass Disable” is selected. The mode change would be active only after
the UPS is turned on.

UPS, the UPS will get into the inverter mode, the LCD screen will
indicate the state of the UPS.
(2) Without utility pow er connecting:
If UPS is cold start without utility power connecting, user need to
push “I” button twice, first pushing “I” button is for UPS to get
power, and second pushing “I” button continuo usly for more than 1
second is for UPS to turns on, the UPS will get into the inverter
mode. In fact, the two pushing “I” button is to make further sure
user operation for turning on UPS, the LCD screen will indicate the
state of the UPS.
Note: The default setting for bypass mode is no output after UPS
is connecting utility power and breaker is turned on. This can be
configured by monitoring the LCD panel or firmware.
5.5 Test function:
Test the function of the UPS system by pressing the On-Switch “I” for
more than 1 second, the UPS would detect whether the battery is
connected or the battery is low. And the UPS could also do the test
automatically and periodically, the period time could be set by user.
5.6 Turn off the UPS:
(1) In Inverter Mode:
Press “ “ button continuously for more than 1 seco nd to turn off
the UPS, the UPS will get into no output or bypass mode. At this
time, the UPS might has o utput if bypass is enabled. Disconnect
the utility power to turn off the output.
(2) In Battery Mode:
Press “ “ button continuously for more than 1 second to turn off
the UPS, the UPS will be turned off completely.
