• Keep a new transducer on hand to use for test.
• No display does not mean the sprayer is not pres-
surized. Before repair,
Relieve Pressure , page 11.
NOTE: Do not allow sprayer to develop fluid pressure
without transducer installed. Leave drain valve open if
test transducer is used.
1. For sprayers with digital display, see Digital display
Messages.
2. Remove screws (12) and cover (50).
3. Turn ON/OFF switch ON.
4. Observe LED operation and reference following
table:
Display Sprayer Operation Indicates What To Do
No Display Sprayer stops. Power is not
applied. Sprayer may be
pressurized. Loss of power. Check power source. Relieve pressure
before repair or disassembly.
psi/bar/MPa Sprayer is pressurized. Power is
applied. (Pressure varies with tip
size and pressure control setting.) Normal operation. Do nothing
E=02 Sprayer may continue to run.
Power is applied. Runaway pressure.
Pressure greater than
4500 psi (310 bar, 31
MPa) or damaged
pressure transducer Replace motor control board or pressure
transducer.
E=03 Sprayer shuts down and LED
continues to blink three times
repeatedly. Power is applied. Pressure transducer is
faulty or missing. Check transducer connection. Open drain
valve. Substitute new transducer for
transducer in sprayer. If sprayer runs,
replace transducer.
E=04 Sprayer shuts down and LED
continues to blink four times
repeatedly. Power is applied. Line voltage is too high. Check for voltage supply problems.
E=05 Sprayer does not start or stops and
LED continues to blink five times
repeatedly. Power is applied. Motor fault. Check for locked rotor, shorted wiring or
disconnected motor. Repair or replace
failed parts.
E=06 Sprayer stops and LED blinks six
times repeatedly. Power is applied. Motor is too hot or there
is a fault in motor thermal
device. Allow sprayer to cool. If sprayer runs
correctly when cool, check motor fan
function and air flow. Keep sprayer in cool
location. If sprayer does not run when cool
and continues to blink six times, replace
motor.
- - - - Power is applied. Pressure is less than 200
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
pressure. Refill paint pail. Check for leaks or clogged
pump inlet. Repeat Startup procedure.
E=10 Sprayer does not start or stops and
LED continues to blink 10 times
repeatedly. Power is applied. High control board
temperature. •
Make sure motor air intake is not
blocked.
•
Make sure control board is properly
connected to the back plate and that
conductive thermal paste is used on
the power components.
