Motor Control Diagnostic Codes
16 312066ZAF
E25: High line voltage
Supply voltage is too high. Check Reactor voltage
requirements, page 75.
E26: Low line voltage
Supply voltage is too low. Check Reactor voltage
requirements, page 75.
E27: High Motor Temperature
1. Motor temperature is too high. Reduce pressure,
gun tip size, or move Reactor to a cooler location.
Allow one hour for cooling.
2. Check fan operation.
3. Ensure there is no obstruction around the fan area
that would cause lack of airflow; ensure the
motor/fan shroud is installed.
4. Ensure the unit is being operated with the front
cover on.
5. Ensure the brush wear/over temp switch wire
assembly is plugged into J7 (E-20/E-XP1) or J6
(E-30/E-XP2) of the motor control board.
6. With the main power off, unplug the wire harness
from J7 (E-20/E-XP1) or J6 (E-30/E-XP2) on the
motor control board and install a jumper wire on
pins 1 and 2. Turn the main power back on.
If E27 is gone:
If the E27 error is gone and the motor is truly not
overheated, then the problem can be in the motor/motor
wire harness assembly. Measure the resistance
between the two yellow wires that go to pins 1 and 2 of
the motor connector. If there is an open connection, the
thermal overload switch is open or there is a broken wire
inside the motor, or a broken wire in the motor harness.
If the E27 error code is still there, double check if pins 1
and 2 are jumpered properly. If jumpered properly, then
it would appear that the problem is with in the motor
control board.
E28: High current in motor
Check the motor control board:
1. Turn the master power off.
2. Disconnect socket J4 (E-20/E-XP1) J1
(E-30/E-XP2) on the motor control board.
3. Turn the master power back on.
4. If the E28 error did not go away then there is a
problem with the motor control board. Replace
board, page 36.
Check the motor:
1. Check to see if the motor rotates freely.
2. Check to see if the brushes are damaged.
3. Check that the voltage going to the motor is good.
4. Check the three wire (yellow, yellow, orange) motor
connector to the motor board. A gentle tug on each
wire individually at the connector should identify the
loose wire. If a wire pulls out, bend the locking tab
on the crimp end, insert the wire until it seats and
repeat gentle tug.
5. If the above does not resolve the problem, replace
the motor, page 35.
E29: Brush Wear
1. Check for normal brush wear, which causes the
brush sensor to come in contact with the motor
commutator. Replace the brushes, page 32.
2. Check spade plug. The spade plug inside the motor
housing may be twisted and contacting the
commutator side of the brush sensor assembly,
causing a false alarm. Follow the orange wire
coming from J7 (E-20/E-XP1), or J6 (E-30/E-XP2),
up to the spade connector on the motor. Using a
flashlight, ensure the spade plug assembly is not
making contact with the metal housing of the brush
assembly.
CAUTION
Prolonged operation of motor after a brush wear
warning may result in failure of motor and motor
control board.
