3.7.2.3. Setting Procedure for NEW version of CPU
1.Short the JP3 of the control board by jumper cap. Do Not Connect Battery.
2.Add 110V/60Hz or 220V/50Hz and Adjust Charger Voltage: 41.4V for MS1K/MS1KR, 82.8V for
MS2K/MS2KR and 110.4V for MS3K/MS3KR. (Important: The input voltage must be precisely110V/60Hz or
220V/50Hz)
3.Software Setting(This part is not nessary if the UPS already been set)
。
4.Switch on the front switch of the UPS and adjust the output voltage to
220V/110V. To decrease or increase the voltage, please follow the chart below:
Output Voltage Adjustment
DIP SW1
DIP SW2
DIP SW3
DIP SW4

Remarks: to enable the adjustment, please push the Test Switch to
Increase or decrease the voltage till the desired one.
5.Set the DIP SW1 ON and DIP SW2 OFF, then add a resistance load
Of 700W, 1400W and 2100W for MS1K/MS1KR, MS2K/MS2KR,
and MS3K/MS3KR respectively. (For an UPS already been set, the load is not nessary)
Read the input voltage and batteryVoltage from the multi-meters connected to see
whether they are at the desired 110Vac or 220Vac and 41.4V/82.8V/110.4Vac.
6.Then, push the Test Switch to see whether the voltage setting is done Successfully.
Tolerance of Input Voltage
CPU Action
Setup Condition
CPU Read Value <10%
CPU automatically adjusts and
Buzzer beeps twice.
Success
CPU Read Value>10%
Buzzer beeps continuously
Failure
Remarks: If the setup is in failure, you shall proceed the adjustment all over again
Or return for repair.
7.Switch off the UPS and remove the jumper cap from the JP3.
8.In most of cases
，
The Calibration Procedure is NOT nessary, even after replace CPU and Logic Board.
9.For the new versions of CPU, output voltage is selected by software(step 3).
