The "Troubleshooting Guide" (Figure 9) pro-
vides information for troubleshooting the power
supply when improper operation is obtained and
the problem has been traced to the power sup-
ply. Proper troubleshooting should ONLY be
accomplished with specific test equipment by
qualified electronics technicians or authorized
Ransburg representatives.

Before troubleshooting, ensure that the power
supply is plugged into a live outlet of the appro-
priate voltage. All electrical measurements in
the "Troubleshooting Guide" (Figure 9) are
nominal and may vary as much as ±10% de-
pending on the test conditions and the test
equipment used. Refer to Figures 7 and 8 for
location of parts called out in the "Troubleshoot-
ing Guide".

For bench testing, jumper JP4 should be used
to trigger the high voltage output (see "PC
Board Test Jumper" previously discussed in
this section).

Procedures outlined in the "Trouble-

shooting Guide" (Figure 9) require measure-
ment of voltage potentials that can cause

Diagnostic LED's

There are two diagnostic LED's located on the
relay board inside the cabinet (see Figure 8).
LED1 is a green LED that indicates 24 VDC in-
put is being received from power supply 2SUP.
LED1 should be lit whenever the power supply
ON/OFF switch is ON. LED2 is a red LED that
indicates 24 VDC is being output to the gun mo-
tor. LED2 should be lit whenever the toggle
switch at the back of the gun is turned ON.
