Problem
System sees two or
more identical Fluid
Control Modules.
System sees two or
more identical Booth
Control Modules.
Pump was driven to
its maximum allowed
speed.
This is a manual stall
test failure when the
pump cannot build
pressure to the target
"Stall Test Pressure."
Will fault after 30
seconds.
Pump stall test failed;
pump did not stall on
the up stroke.
Cause
More than one Fluid
Control Module is
connected in the
system.
More than one Booth
Control Module is
connected in the
system.
System has a leak
or open valve that is
allowing unrestricted
flow.
Pump is cavitating,
cycling without
restriction.
Viscosity of material is
too thin for nozzle size.
No material in the
pump or line.
Leak in the system.
Valve failure, seal
failure, worn rod or
cylinder.
Solution
Check the system and
remove the extra fluid
control module.
Check the system
and remove the extra
booth control module.
Inspect system for
leaks.
Verify pump is being
supplied material.
Reduce nozzle size
to create more
restriction. Reduce
paint pressure to lower
the flow rate.
Make sure the pump
and down stream color
line are loaded with
material.
Determine if leak is
external or internal
by visually inspecting
the system for fluid
leakage. Fix all loose
or worn hoses, fittings,
and seals. Inspect
all valve seats and
needles for wear, and
replace worn piston or
throat seals.
Replace inlet and
outlet valve and
seal for up stroke.
Replace piston and
throat seals. Replace
rod and cylinder as
necessary.
