by using BUS tiny regulation command. (BUS voltage can be regulated about
0.5V every point by using BUS voltage tiny regulation command).
2. INV output voltage regulation: When the UPS run into the Inverter mode, measure
the output voltage with the multimeter. then regulate the output voltage to 220
±
0.5V by using output voltage regulation command. (INV output voltage can be
regulated about 0.8V every point by using output voltage regulation command).
3. UPS ID setting: Set ID for every UPS by UPS ID setting command.
After finished all the operation, turn off the UPS and run into the bypass mode.
switch off the input switch of UPS, and wait until fans stop. Then switch on the
input switch, turn on the UPS and UPS will run into Line mode, measure the BUS
voltage and output voltage, be sure all the regulations have been taken effect, and
then, regulate the next UPS.
Notes:
1. Be sure the ground of the UPS connect earth safely while parameter regulation.
2. The new assembly UPS must be regulated.
3. The UPS who have been replaced CNTL/PSDR must be regulated again.
4. All the commands use capital letters.
5. All the above parameter regulation can not be accumulated.
6. All the regulation will be saved in CPU of the CNTL. So if you want to re-regulate
the CNTL, you should reset the CPU and clean all the parameters setting by the
following commands:
BUSP+00
BUSN+00
V+0
After all the commands have been executed, CPU be reset and then we can
re-regulate the UPS according to the above regulation process.
7. If you are not sure whether the CNTL has been regulated, reset before your
regulation.

The Fault code is
“05”;
The UPS beeps
continuously.
When one of the follow conditions have been meet, the fault
signal will be sent.
1. The time that the +Bus voltage keeps higher than 450V or the
–BUS voltage keeps lower than –450V is more than 80 ms.
2. The time that the +Bus voltage keeps higher than 400V or the
–BUS voltage keeps lower than –400V is more than 1.5s.
3. The time that the +Bus voltage keeps lower than 230V or the
–BUS voltage keeps higher than –230V is more than 1.5s.
