Ransburg MMA-570 Direct_Ind Charge Atomizer A13366 - Manual (Page 78)

Turbine is not rotating
Fluid valve does not actuate
Clogged fluid tube/fluid tip
Bad transceiver module
Fluid valve open
Fluid valve seat damaged or worn
Insufficient back pressure to fluid
regulator
Fluid regulator does not control
flow (system)
Verify rotation of turbine (the paint valve
air pilot must be interlocked with the tur-
bine speed feed back signal to ensure that
paint does not flow into the air bearing).
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.
Remove and inspect fluid tube or fluid tip.
Replace transceiver module.
a. Remove air pilot signal.
b. If still open, replace fluid valve.
Replace fluid valve seat.
Replace fluid tip with the next smaller
inner diameter size.
Disassemble fluid regulator and inspect
for failed components (system).
