Alarm
Code
Alarm Problem When Active Cause Solution
DAAX
DABX
Pump runaway, above 80
cpm for 10 sec.
Always No material in pump or lines;
no fluid restriction.
Refill material in tank or hoses;
install fluid tip.
DDAX
DDBX
Pump cavitation; dives
more than 1/2 of stroke.
Spray No fluid or valve closed. Refill supply and open inlet valve.
Material is too cold or thick. Increase material temperature to
reduce viscosity. Follow Heat
Fluid, page 40. Shear material
with agitation to reduce viscosity.
Pump inlet check valve not
closing.
Clear debris from check valve. Or
replace ball, seat, and seal.
Feed pump not providing
material.
Check feed pump (if used).
Inlet strainer plugged (if used). Check and clean strainer. See
your proportioner repair manual.
F7AX
F7BX
System Detects
Unexpected Pump
Movement (Fluid Flow).
Spray Recirculation valve or dosing
valve open or leaking for more
than five seconds.
Close or repair recirculation valve,
and run Pump Test. Follow Pump
and Metering Test, page 51.
F8RX No movement occurred in
circulation mode
Circulation Pump did not move for 5
seconds while in circulation.
User may have attempted to
spray in circulation mode.
Use spray mode for spraying.
P1AX
P1BX
Pressure low. Spray, Pump
Test, Leak
Test
Fluid pressure is below 1000
psi (7 MPa, 70 bar) for spray
mode, or below 1500 psi (10.3
MPa, 103 bar) for test modes).
Increase main air regulator.
P4AX
P4BX
Pressure high. Always Fluid pressure is above
maximum.
Decrease main air regulator.
P4RE Pressure high. Recirculation Pressure is above maximum
advisory limit of 3000 psi (21
MPa, 210 bar) on A side.
Decrease pump air regulator
pressure.
P5RE Pressure high. Recirculation Pressure is above maximum
warning limit of 5200 psi (35.9
MPa, 359 bar) on A side.
Decrease pump air regulator
pressure.
P9AX A pump pressure is
abnormally low compared
to B pump pressure.
Spray A air motor is icing up causing
restriction and lower fluid
pressure.
Open the air motor de-ice bleed
air controls. Allow ice to melt. Dry
compressed air. Heat compressed
air.
Use a smaller tip.
A pump is binding. Repair lower. See manual your
proportioner repair.
A motor is hanging up. Repair air motor. See your
proportioner repair manual.
