Sprayer is pressurized. Power is applied.
(Pressure varies with tip size and pressure
control setting.)
Normal operation. Spray.
E=02 Sprayer may continue to run. Power is
applied.
Pressure greater than
4500p psi (310 bar, 31
mpa) or a pressure trans-
ducer is faulty.
Replace pressure control board
or pressure transducer.
E=03 Sprayer stops. Power is applied. Pressure transducer
faulty, bad connection or
broken wire.
Check transducer connection.
Open drain valve. Substitute
new transducer for transducer
in sprayer. If sprayer runs,
replace transducer.

lem.
E=05 Sprayer does not start or stops. Power is
applied.
Motor fault. Check for locked rotor, shorted

psi (14 bar, 1.4 MPa)
Increase pressure if desired.
Drain valve may be open.
EMPTY Sprayer stops. Power is applied. Empty paint pail. Loss of
