Problem Problem Problem
Pump was unable to
reach its drive position.
Pump moved beyond its
drive position.
Record of pump homing
is complete.
Pump tried but was not
able to move to the
home position within a
specified amount of time.
Pump tried but was not
able to move to the park
position within a specified
amount of time.
Record of pump
completing an auto
pressure relief.
Record of pumps being
auto parked.
The pump was unable to
maintain its target flow
rate.
The Mix Unit was unable
to maintain it's target flow
rate.
Cause
Cause Cause
Not enough air is
supplied to the dosing
valves.
The pressure at the
pump outlet is too high.
The pump was knocked
out of position.
An indication on the
display that the pump
completed the home
function
Pump dose valves did
not actuate.
Motor could not drive
pumps and linear
actuator.
Pump stroke length is
shortened by mechanical
system tolerance.
Pump dose valves did
not actuate.
Pump is filled with thick
paint and could not drive
piston to end of stroke.
Motor or drive is worn or
damaged.
Pump outlet pressure
exceeded relief
threshold.
The auto pump
park operation was
completed.
There is a restriction
in the hose or gun that
is preventing the pump
from dispensing at its
target rate.

System Errors
Solution
Solution Solution
Ensure that at least 85
psi is being supplied to
the dosing valves.
Check for an obstruction
downstream of the pump
that would increase
pressure. Ensure the
feed pressure is within
1/2 – 1/3 of the target
pressure
There is no fluid pressure
at the outlet of the pump;
run the pump at a lower
pressure to fill the lines.
Check that the feed
pressure is not more
than the target pressure.
No action required.
Verify air pressure to
solenoid valves. Verify
the valves are actuating.
Verify motor is driving
the pump.
Verify correct assembly
of linear actuator and
pump piston rods. See
pump manual.
Visually inspect valves
to ensure they are
operating properly; verify
they have air pressure
above 85 psi (0.6 MPa,
6.0 bar).
Observe motor and drive
assembly to verify that
the motor is generating
force.
No action required.
No action required.
Check that the gun
is triggered and for
restrictions in the hose.
Check that the gun
is triggered and for
restrictions in the hose.
