16: Output voltage calibration
Interface
Setting
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
Down
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.
17: Phase auto adapt enable/disable
Interface
Setting
Parameter 2:
it always shows
PH.A
as phase auto adapt
function.
Parameter 3:
Enable or disable phase auto adapt function. You
may choose following two options:
DIS:
disable phase auto adapt function. Then, the UPS only can
accept one condition which the phase difference of L2 and L1 is
120
º
and phase difference between L3 and L2 is 120
º
.
ENA:
enable phase auto adapt function. Then, the UPS can accept
either inputs of L1, L2, L3 in the same phase or the phase
difference between L2 and L1 with 120
º
, L3 and L2 with 120
º
or
phase difference between L2 and L1 240
º
, and L3 and L2 with
240
º
.
3-8. Operating Mode/Status Description
Following table shows LCD display for operating modes and status.
(1) If the UPS is in normal operation, it will show four screens one by one, which represents 3 phase input
voltage (L1, L2, L3) and frequency in turns.
(2) If parallel UPS systems are successfully set up, it will show one more screen with “
PAR
” in parameter 2
and 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;
Parallel screen
Warning screen
(3) If some errors occur in the UPS, it will show one more screen to represent the warning situation. In the
warning screen, it can show up to 3 error codes and each code indicates one error. You can find the
meanings of error codes in the warning code table.
Operating mode/status
UPS Power On Description
When UPS is powered on, it will enter into this mode for a few seconds for
initializing the CPU and system.
