Ransburg Evolver 303 Solvent Applicator A11976-XXX - Manual (Page 53)

TROUBLESHOOTING GUIDE (Cont.)
Note: To check for fluid leaks, it is easiest to first remove the applicator from the test station and re-
move the shroud from the applicator. Then the applicator can be remounted to the test station. Leak
detector may be used at all appropriate sources. Be certain to wipe off all residual solution using a
non-conductive solvent such as Naphtha.
General Problem Possible Causes Corrective Action
5. Faulty low voltage connec-
tions (usually indicated by
MicroPak feedback fault
light)
6. Faulty high voltage connec-
tion
7. MicroPak or cascade failure
8. Improper color change (i.e.
paint or solvent in dump line)
1. Low or no high voltage
2. Poor grounding of parts
being coated
3. Excessive target distance
1. Applicator mounting nut is
loose
2. O-ring is missing
3. O-ring is damaged
5. a. Make sure quick disconnection electrical
connection is aligned and clean.
b.Check low voltage connection at cascade.
6. Remove cascade and check continuity be-
tween cascade connection and turbine shaft.
7. Refer to "MicroPak" service manual for de-
tailed "Troubleshooting Guide".
8. Optimize color change.
1. Verify high voltage at bell cup edge. Normally,
a high voltage setting of 70 -100 kV is
appropriate for most applications.
2. Verify that parts being coated are properly
grounded (the electrical resistance between
the part and ground must not exceed 1 megohm).
3. The recommended target distance is between
10-14-inches (.25m-.36m) (see "Target Dis-
tance" in the "Operation" section of this
manual).
1. Tighten mounting ring.
2. Install o-ring.
3. Visually inspect for damage and replace.
