Motor Control Diagnostic Codes
14 312066ZAF
E21: No component A
transducer
1. Check transducer A connection at J3 on motor
control board, page 36, and clean contacts.
2. Reverse A and B transducer connections. If error
moves to transducer B (E22), replace transducer A,
page 38. If error does not move, replace motor
control board, page 36.
E22: No component B
transducer
1. Check transducer B connection at J8 on motor
control board, page 37, and clean contacts.
2. Reverse A and B transducer connections. If error
moves to transducer A (E21), replace transducer B,
page 38. If error does not move, replace motor
control board, page 36.
E23: High fluid pressure
1. Perform the Pressure Relief Procedure, page 25.
Verify low pressure with analog gauges. Turn main
power OFF then ON . If error
persists, do checks below.
1. Check the jumpers and the wiring. Check jumper on
motor control board J10 for E20 and E-XP1, or J7
for E30 and E-XP2, pins 7-10, page 36.
2. Remove, clean and re-install the pressure
transducer leads
If the jumpers and the wiring are in good working
condition and you still have the error, then you will need
to replace the “A” and “B” pressure transducers.
3. To determine if it’s the “A” or the “B” transducer, you
will need a known good Reactor pressure
transducer to use as a “test” transducer. The test is
done without removing the existing pressure
transducers from the fluid manifold.
a. Unplug the “A” transducer from the Motor
control board socket (page 38) and replace with
“test” transducer.
b. Turn on the Reactor master power.
• If the error is gone, turn off the Reactor main
power, remove test transducer, and replace “A”
transducer.
• If the error persists, unplug the “test” transducer
from the “A” socket, and reinstall the “A”
pressure transducer back into the “A” socket.
Repeat this test procedure on the “B” side.
4. If the error persists and no root cause is found
through the above testing, replace the motor control
board, page 36.
E24: Pressure Imbalance
NOTE: If the pressure difference between components
A and B exceeds 500 psi (3.5 MPa, 35 bar), an E24 will
occur. This default value is adjustable; see the operation
manual.
NOTE: E24 can be an alarm or a warning, as desired.
Set DIP switch on motor control board ON for alarm,
OFF for warning. See page 36.
Fast E24 Errors
Fast E24 errors occur:
• Within 10 seconds of turning the pumps on.
• As soon as you trigger the gun.
Causes of Fast E24 Errors
• one side of the gun is plugged.
• a pressure transducer has failed.
• damaged pump seals or check valve.
• no feed pressure or empty material drum
• plugged heater.
• plugged hose.
• plugged manifold.
• one PRESSURE RELIEF/SPRAY valve is leaking or
is set to PRESSURE RELIEF/CIRCULATION
