z
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 fro 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.
z
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 the phase order which L2 delay L1 120º, L3 delay L2 120º.
ENA
: Enable phase auto adapt function. Then, the UPS can accept
either inputs of L1, L2, L3 in the same phase or the phase order
which L2 delay L1 120º, L3 delay L2 120ºor L2 delay L1 240º, L3
delay L2 240º.
3.8. Operating Mode/Status Description
The 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, that represent 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 meaning
of each error code in the warning code table.
Operating mode/status
Description
When UPS is powered on, it will enter into this mode for a few seconds for
initializing the CPU and system.
