16: Output voltage calibration
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:
voltage.
Parameter 3:
value of the output voltage, and you can
calibrate it by pressing Up or Down according
to the measurement from an external voltage
meter. The calibration result will be effective
by pressing Enter. The calibration range is
limited within +/-9V. This function is normally
used for parallel operation.
17: Charging current setting
Parameter 2:
at 1A , 2A, 3A or 4A (001 ~ 004).
Parameter 3:
there is deviation between setting current and real
measured current, please use this parameter to
calibrate the charging current.
± 0~± 5:
calibrate charging current. This setting number is
the first number after the decimal point.
0 0 4 3
The calibrated formula is listed as below:
Setting charging current = "real measured current"
+ or – "value setting in parameter 3". For example,
if setting charging current is 4A, but real current is
detected as 3.7A, please set up calibrated current as
+ 3.
Setting charging current 4A = real measured current
3.7A + 0.3A
NOTE!
If you plan to connect more than one battery cabinets to one UPS, then you should
set Charging current as in second table from page 38.

6.6. Operating mode and status description

If 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;
• AC mode
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.
LCD display
• ECO mode (Efficiency Corrective Optimizer)
When the input voltage is within voltage regulation range and ECO mode
is enabled, UPS will bypass voltage to output for energy saving.
