TROUBLESHOOTING GUIDE (Cont.)

Note: To check for fluid leaks, it is easiest to first remove the applicator from the test station and remove 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 be-

ing 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 between

cascade connection and turbine shaft.

7. Refer to "MicroPak" service manual for detailed

"Troubleshooting Guide".

8. Optimize color change.

1. Verify high voltage at bell cup edge. Normally,

a high voltage setting of 70 -100 kV is appropri-

ate 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.
