The "Troubleshooting Guide" provides information
for troubleshooting the power supply when improper
operation is obtained and the problem has been
traced to the power supply. Proper troubleshooting
should ONLY be accomplished with specific test
equipment by qualified electronics technicians or
authorized ITW Ransburg representatives.
Before troubleshooting, ensure that the power
supply is plugged into a live outlet of the appropriate
voltage. All electrical measurements in the
"Troubleshooting Guide" are nominal and may
vary as much as
+
/- 10% depending on the test
conditions and the test equipment used. Refer to
Figures 6 and 9 for location of parts called out in the
"Troubleshooting Guide" in this section.
For bench testing, jumper JP4 should be used to
trigger the high voltage output (see "PC Board
Test Jumper" discussed at the beginning of the
"Maintenance" section).

Before going through the trouble of a
complete bench test, jumper JP4 on the
main PC board to trigger the high voltage
and see if the suspected problem goes
away. If it does, replace the high voltage
trigger device (flow switch, pressure
switch, PC contact, etc.) or repair the in-
ternal wiring of the power supply con-
nected to the trigger device, and test
again. If the problem does not go away,
then proceed with a bench test.
