DKD#
Alarm
Position
Failed Pump
#
Pump was unable to
reach its drive position.
The pressure at the
pump outlet is too high.
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.
DKF#
Alarm
Position
Overspeed
Pump #
Pump moved beyond its
drive position.
The pump was knocked
out of position.
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.

system tolerance.
Verify correct assembly
of linear actuator and
pump piston rods. See
pump manual.
Pump dose valves did
not actuate.
Visually inspect valves
to ensure they are
operating properly; verify
they have air pressure
above 85 psi (0.6 MPa,
6.0 bar).
EF1#

Shutdown
Pump #
Pump tried but was not
able to move to the park
position within a specified
amount of time.
Pump is filled with thick
paint and could not drive
piston to end of stroke.

damaged.
Observe motor and drive
assembly to verify that
the motor is generating
force.
