Troubleshooting
Capacitor Charging Fault
Turn unit on and wait 1 minute
Shut down power and
repair power supply to
the correct voltage.
Replace the AP1
control panel
Restart
unit
Is voltage higher than 200 v?
Measure the AC voltage between
terminals “L” & “N” on the board XT
power supply
Check the connection of the
reactor, is the wiring correct?
End Troubleshooting
Yes

No
Is voltage within 10% or
nameplate rating
• Use AC voltmeter to check proper voltage on terminals “L” & “N” on the terminal board. Voltage should
be within 10% of voltage on nameplate.
• Is the reactor (L) correctly connected? Check for damaged reactor.
Is fault
corrected?
Power off unit for 20 minutes, then use DV
voltmeter to measure the two leads on the
capacitor until the voltage is < 20v
Use a DC voltmeter to measure the voltage on the
two terminals of the electrolytic capacitor
Faulty AP1
Connect
correctly
Power up
unit, is fault
corrected?
Yes
No
Replace AP1
control panel
Yes
