1. Turbine is not rotating
2. Fluid valve does not actu-
ate
3. Clogged fluid tube/fluid tip
4. Bad transceiver module
1. Fluid valve open
2. Fluid valve seat damaged
or worn
1. Insufficient back pressure
to fluid regulator
2. Fluid regulator does not
control flow (system)
1. Atomizer mounting ring is
loose
2. O-ring is missing
3. O-ring is damaged
1. O-ring is damaged
2. Fluid tubing not properly
installed or tightened.
1. Damaged o-ring(s) on
outer diameter of valve
body
2. Damaged or worn needle

bly
1. Verify rotation of turbine (the paint valve air
pilot must be interlocked with the turbine
speed feed back signal to ensure that paint
does not flow into the air bearing).
2. a. Verify that air pilot signal is present.
b. Fluid valve air pilot pressure is too low.
Increase air pressure to 70 psig minimum.
c. Replace fluid valve.
3. Remove and inspect fluid tube or fluid tip.
4. Replace transceiver module.
1. a. Remove air pilot signal.
b. If still open, replace fluid valve.
2. Replace fluid valve seat.
1. Replace fluid tip with the next smaller inner
diameter size.
2. Disassemble fluid regulator and inspect for
failed components (system).
1. Tighten mounting ring.
2. Install o-ring.
3. Visually inspect for damage and replace.
1. Replace o-ring.
2. Inspect and retighten.
1. Replace o-ring(s).
2. Replace valve assembly.
