18: Output A 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 A 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.
19: Output B 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 B 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.
*It will display number 1 under
to represent the output B
voltage.
20: Output C 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 C 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.
*It will display number 2 under
to represent the output C
voltage.
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 seven screens one by one, which represents 3 phase input
voltages (An, bn, Cn), 3 line input voltages (Ab, bC, CA) 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;
