4.9. Power Input Tolerance Check

4.9.1. Input Voltage Check:

Follow below procedure to perform Input voltage Check:
1. Check the current input voltage adaption of system and treat current input voltage as
parameter V1.
There are 7 standard voltage configurations for different countries as follows:
100V/110V/120V/200V/220V/230V/240V
The voltage adaption for 115V is the same with the 110V; V1=110V;
2. Remove the WKS back cover and Power Distribution Unit Board protection cover.
3. Plug out the connectors PJ3 and PJ10 on Power Distribution Unit Board;
4. Switch on the breaker on WKS;
5. Test the voltage between the terminal J1-9 and J1-12 by multi meter and treat the voltage as
parameter V2;
6. Long press the switch on/off button, until the WKS power on switch inner LED starts to flash;
7. Test the voltage between the test points TP19 (red) and TP25 (black) on the PDU board with
the DC voltage shift of multi meter. The voltage shall be within (V2*6.25/V1)±0.01V
Example 1:
If the voltage adaption is 115V, then the V1 is 110V, and the actual tested input voltage is
117V (between J1-9 and J1-12), so the V2 is 117V.
So the voltage between the TP19 and TP25 shall be within (117*6.25/110)±0.01.
Example 2:
If the voltage adaption is 220V, then the V1is 220V, and the actual tested input voltage is
215V (between J1-9 and J1-12), so the V2 is 215V;
So the voltage between the TP19 and TP25 shall be within (215*6.25/220)±0.01.
8. If the voltage fulfill (V2*6.25/V1)±0.01V, plug in connectors PJ3 and PJ10 removed in step3,
recover the Power Distribution Unit Board protection cover and WKS back cover.
If the voltage do not fulfill (V2*6.25/V1)±0.01V, refer to 4.9.2 to perform calibration.
