No.

Symptom

Possible cause

Measure

W21*
WRN OVER VOLT

Occurred in the event of an output

overvoltage.

Check the load impedance.
If the symptom frequently occurs even
though there is no problem with the load,
replace the product.

W22*
WRN OVER CUR

Occurred in the event of an output

overcurrent.

Check the load impedance.
If the symptom frequently occurs even
though there is no problem with the load,
replace the product.
