15: I nverter voltage adjustment
I nterface
Setting
Parameter 2:
you may choose
Add
or
Sub
to adjust inverter
voltage
Parameter 3:
the voltage range is from 0V to 6.4V, the default
value is 0V.
16: Output voltage calibration
I nterface
Setting
When the output voltage can not be detected(less than 50VAC),
this menu will be reserved, “
” will be displayed in parameter
2 and parameter 3.
Parameter 2:
it always shows
OP.V
as output voltage.
Parameter 3:
it shows the internal measurement value of the
output voltage, and you can calibrate it by pressing
Up
or
Dow n
according to the measurement from an external voltage meter.
The calibration result will be effective by pressing
Enter
. The
calibration range is limited / -9V. This function is normally
used for parallel operation.
3- 8. Operating Mode/ Status Description
I f parallel UPS systems are successfully set up, it will show one more screen with “ PAR” in parameter 2 and
be assigned number in parameter 3 as below parallel screen diagram. The master UPS will be default
assigned as “001” and slave UPSs will be assigned as either “ 002” or “ 003” . The assigned numbers may be
changed dynamically in the operation;
Operating mode/ status
AC mode
Description
When the input voltage is within acceptable range, UPS will provide pure
and stable AC power to output. The UPS will also charge the battery at
AC mode.
