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 pumps auto
park complete.
Record of pump #
pressure automatic
pressure relief complete.
The pump was unable to
maintain its 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.
An indication on the
display that the system
parked the pump
automatically.
An indication on the
display that the system
automatically opened the
dump valve to relieve
pressure.
There is a restriction
in the hose or gun that
is preventing the pump
from dispensing at its
target rate.
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 not 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 1/2 – 1/3
greater 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 ad for
restrictions in the hose.
