3.7.2.2. Setting Procedure for EARLY version of CPU ( MS01013F
、
MS03014B and those before MS0731)
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. Switch on the front switch of the UPS and adjust the output voltage to
Desired one. To decrease or increase the voltage, please follow the chart below:
Output Voltage Adjustment DIP SW1 DIP SW2 DIP SW3 DIP SW4
Decrease O/P Voltage OFF OFF OFF OFF
Increase O/P Voltage OFF ON OFF OFF
Remarks: to enable the adjustment, please push the Test Switch to
Increase or decrease the voltage till the desired one.
4. 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. Read the input voltage and battery
Voltage from the multi-meters connected to see whether they are at
The desired 110Vac or 220Vac and 41.4V/82.8V/110.4Vac.
5. 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.
6. Switch off the UPS and remove the jumper cap from the JP3.
7. To choose the model type and output voltage, adjust the DIP Switch 3-4 at the rear part of logic
board , following the tables below:
Voltage 100/200Vac 110/220Vac 115/230Vac 120/240Vac
DIP-SW3 OFF OFF ON ON
DIP-SW4 ON OFF OFF ON
8. In most of cases
，
The Calibration Procedure is NOT nessary, even after replace CPU and Logic Board.
9. For a UPS already been set, when doing procedure 4, the load is not necessary.
