Problem
There has been no flow
or low flow during a
pump fill operation.
There has been no flow
or low flow during a
pump purge operation.
The pump flow
exceeded 20 cc/min
flow coming into Idle
mode.
No flow while mixing.
The pump flow rate
did not stabilize while
entering Idle mode.
Air flow switch is
active while solvent,
diluted material, or an
unknown material is in
the gun.
Cause
There is a restriction on
the outlet side of the
pump or color stack.
Thick viscosity paint
requires more pressure
to pump.
The pumps do not
have to move for the
system to build enough
pressure to meet the
setpoint.
Restriction in the outlet
side of the pump or
color stack resulting in
the solvent flow being
too low.
There is a leak in the
system or the gun was
open when the system
went into Idle mode.
Restriction in the outlet
side of the pump or
color stack.
Potential leak in the
system.
Atomizing air supply
was not shut off before
purging or filling spray
gun.
System Errors
Solution
Make sure there are no
restrictions in the color
stack and that the dump
valve is actuating.
Increase non-mix
pressure if necessary
to create flow during
the fill function.
Increase non-mix
pressure if necessary
to create flow during
the fill function.
Make sure there are
no restrictions in the
system. Increase
non-mix pressure if
necessary to create
flow during the purge
function.
Verify there are no
leaks in the system.
Make sure the air flow
switch is actuating
properly. Do not
trigger the gun without
atomizing air.
Make sure there are
no restrictions in the
system.
Check the system for
leaks and run manual
stall test.
Make sure atomizing
air is shut off before
purging or filling the
spray gun. Use an
AA cutoff valve on the
atomizing air supply.
