P9BX B Pump Pressure is Abnor-
mally Low Compared to A
Pump Pressure.
Spray B air motor is icing causing restric-
tion and lower fluid pressure.
Open the air motor de-ice bleed air
controls. Allow ice to melt. Dry com-
pressed air. Heat compressed air.
Use a smaller tip.
B pump is binding. Repair lower. See XM PFP repair
manual.
B air motor is binding. Repair air motor. See XM PFP

QDAE Dosing Size A Alarm Spray The fluid dosing size is greater than
45 cc when fast dosing is turned off.
Decrease the air motor velocity with
a smaller tip or increase ‘B’ restric-
tion.
The fluid dosing size is greater than
30 cc when fast dosing is turned on.
Decrease the air motor velocity with
a smaller tip or increase ‘B’ restric-
tion.
*QPDX Pot Life Timer Expired. Mixed
Fluid Will Cure in Hoses,
Mixer, and Gun.
Spray Have not sprayed enough volume to
keep fresh mixed fluid in the integra-
tion hose, mixer, whip hose, and
spray gun.
Spray fluid, or flush. Resets when

page 36.
QTAE Dosing Size A Advisory Spray The fluid dosing size is greater than
35 cc when fast dosing is turned off.
Decrease the air motor velocity with
a smaller tip or increase ‘B’ restric-
tion.
The fluid dosing size is greater than
20 cc when fast dosing is turned on.
Decrease the air motor velocity with
a smaller tip or increase ‘B’ restric-
tion.

System Delivering Not
Enough B Component.
Spray B dosing valve will not open. Check for air signal to valve.
B mix manifold valve closed. Open green mix manifold valve.
Pump filter plugged on B side. Use alternate 30 mesh screen. See
manual 311762 for part number.
Clean B pump outlet filter. See man-
ual 311762.

System Delivering Too Much
B Component.
Spray B Dosing valve not closing. Perform Pump Test to test for leak-
age. See Pump and Metering Test,
page 40.
Loosen valve packing nut. See XM
PFP repair manual.
Check air signal at valve top
Repair valve or air solenoid. See XM
PFP repair manual.
Pump filter plugged on A side. Clean filter. See manual 311762.
Use alternate 30 mesh screen. See
manual 311762 for part number.
Inlet air dropping below 80 psi (0.55
MPa, 5.5 bar) while spraying. B dos-
ing valve not closing correctly.
Check air filters. See XM PFP repair
manual.
Use larger air hose.
Use larger compressor.
Use smaller gun tips or less guns to
reduce flow rate.
Solenoid air regulator set below 80
psi (0.55 MPa, 5.5 bar)
