2. After completing the setting, you can type the command in the command area.
3. +BUS voltage regulation: Type “BUSP+/- XX” command (XX is two digits from 00 to 99). Then
press the “ENTER” key, and +BUS voltage will rise (drop) about 0.1V.
4. -BUS voltage regulation: Type “BUSN+/- XX” command (XX is two digits from 00 to 99). Then
press the “ENTER” key, and -BUS voltage will rise (drop) about 0.1V.
5. INV output voltage regulation: Type “V+/- XX” command (X is two digit from 00 to 99) Then press
the “ENTER” key, and output voltage will rise (drop) about 0.2V.
6. INV output voltage setting: Type “VXXX” command (XXX is 208/220/230/240). Then press the
“ENTER” key, and INV output voltage will be set to 208V/220V/230V/240V.
Regulation Process for Single UPS
1. BUS voltage regulation: When the UPS run into AC mode, measure ±BUS voltage with the
multimeter and then regulate ±BUS voltages to 370±0.1V by using BUS regulation command.
(BUS voltage can be regulated about 0.1V every point by using BUS regulation command).
2. INV output voltage regulation: When the UPS run into the Inverter mode, measure the output
voltage with the multimeter, and regulate the output voltage to 230±0.2V by using output voltage
regulation command. (INV output voltage can be regulated about 0.2V every point by using
output voltage regulation command).
Notes:
1. Make sure the ground of the UPS connects to earth safely during parameter regulation.
2. New assembly UPS must be regulated.
3. UPS which have been replaced CNTL/PFC/INV must be regulated again.
4. All the commands use capital letters.
5. All the above parameter regulation cannot be accumulated.
6. All the regulation will be saved in the flash memory of the CNTL when UPS shutdown with
battery connected.
8.2.4 Quick Start
Before any detail check for UPS, please check the components listed in the following table. This action
could help you find problem quickly and make debug procedures go smoothly.
Note:
Make sure that the capacitor voltage is lower than the safety voltage before disassembling any
parts to do checking procedure.
