Problem
Pump failed the stall
test; did not stall on
either the upstroke or
the downstroke.
Pump was detected to
be out of 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.
Cause
Valve failure, seal
failure, worn rod or
cylinder.
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.
Solution
Replace inlet and outlet
valve and seal for up
and down strokes.
Replace piston and
throat seals. Replace
rod and cylinder as
necessary.
Re-enable pump power
to reset pump. Make
sure inlet supply
pressure is not too
high.
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.
