System has a leak
or open valve that is
allowing unrestricted
flow.
Inspect system for leaks.
Pump is cavitating,
cycling without
restriction.
Verify that the pump
is being supplied with
material.
Viscosity of material is
too thin for nozzle size.
Reduce nozzle size to
create more restriction.
Reduce paint pressure to
lower the flow rate.
DA0#
Alarm
Exceeded
Maximum
Flow Pump
#
Pump was driven to
its maximum allowed
speed.
System pressure or
Flow Setpoint is too high
(causing the pump to
work too hard).
Reduce the pressure or
the Flow Setpoint.
No material in the pump
or line.
Make sure the pump and
down stream color line
are loaded with material.
DE0#
Alarm
Leak
Detected
Pump #
This is a manual stall test
failure when the pump
cannot build pressure
to the target “Stall Test
Pressure.” Will fault after
30 seconds.
Leak in the system.
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.
DF0#
Alarm
No Stall Up
Pump #
Pump failed the stall
test; did not stall on the
upstroke.
Valve failure, seal failure,
worn rod or cylinder.
Replace inlet and outlet
valve and seal for
up stroke. Replace
piston and throat seals.
Replace rod and cylinder
as necessary.
DG0#
Alarm
No Stall
Down Pump
#
Pump failed the stall
test; did not stall on the
downstroke.
Valve failure, seal failure,
worn rod or cylinder.
Replace inlet and
outlet valve and seal
for down stroke. Replace
piston and throat seals.
Replace rod and cylinder
as necessary.
DH0#
Alarm
No Stall
Pump #
Pump failed the stall
test; did not stall on
either the upstroke or the
downstroke.
Valve failure, seal failure,
worn rod or cylinder.
Replace inlet and outlet
valve and seal for up and
down strokes. Replace
piston and throat seals.
Replace rod and cylinder
as necessary.
