Troubleshooting
This section introduces troubleshooting measures. Typical symptoms are listed. Check
whether any of the items listed below apply to your case. In some cases, the problem can be
solved quite easily.
p.59
If none of the items apply to your case, we recommend that you initialize the PWX series to
its factory default settings. If the remedy does not correct the problem, contact your Kikusui
agent or distributor.
The power does not turn on
No output is generated

Symptom Items to Check Remedy
The PWX series does not
operate when the POWER
switch is turned on. Is the power cord broken? Exchange the power cord with a new one. p.2
Is the power cord connected correctly? Connect the power cord correctly. p.12
Symptom Items to Check Remedy
No output is generated even
when the OUTPUT switch is
turned on. Is the output voltage set to 0 V and the
output current set to 0 A? Turn the knobs to set the output voltage
and output current to the required values. p.29
Are you using an external con-
tact to turn output on and off? Yes Use the external contact to turn output on. p.71
No Set the external control parameter for turn-
ing output on and off to “off” (CF09: oFF). p.47
Even when the PWX series is
configured so that output is
turned on at power on, the
output is turned off immedi-
ately after the power is turned
on. Has the overvoltage protection (OVP)
function been activated? Limit the set output voltage (CF15: on). If
you do not limit the set output voltage
(CF15: oFF), set the OVP to a value that is
higher than the set voltage. p.49
Has the overvoltage protection2 (OVP2)
function been activated? A voltage that is greater than or equal to
the rated output may be being applied to
the PWX series. Check the voltage that is
being applied. p.96
p.105
Has the overheat protection (OHP/ OHP2)
function been activated? The internal temperature is abnormally
high. Check the operating conditions. After
you have removed the cause of the abnor-
mal temperature, turn the power switch
on. p.40
The air inlet (louver) may be clogged, or
the fan may be broken. Check them. —
Is a shutdown (SD) signal being applied? Set pin 6 of the J1 connector to HIGH (4.5
V to 5 V) or open the pin, or eliminate the
shutdown (SD) signal. p.73
