Fault Code Descriptions, Possible Causes and Solutions
Code Fault Type Description Cause Solution
101 Direction
Motor Direction
Forward, Encoder
Reading Reverse Motor wiring or
encoder signal
wiring is reversed.
Using manual key switch, verify that forward command
produces counter-clockwise (as observed from above)
distributor rotation. If distributor rotates clockwise (as
observed from above), swap any two (2) motor leads to
reverse motor rotation direction. If motor direction is
correct, check blue terminals 3 and 4 for correct wiring
both at junction box and control panel.

201 Encoder
Encoder Channel A
is OFF, Encoder
Channel B is OFF
Controller is
detecting no signal
from encoder
channel A or
encoder channel B.
Verify encoder wiring per instructions in this manual.
Encoder connections are blue terminal blocks. Blue
terminal block #1 should be connected to red encoder
wire. Blue terminal block #2 should be connected to
blue encoder wire. Blue terminal block #3 should be
connected to pink encoder wire. Blue terminal block #4
should be connected to white encoder wire.
202 Encoder
Encoder Channel A
is OFF, Encoder
Channel B is ON
Controller is
detecting no signal
from encoder
channel A,
channel B is always
ON.
Controller is receiving no signal from channel A (blue
terminal block #3) and a constant signal from channel B
(blue terminal block #4). Verify encoder wiring as
referenced above and ensure all terminal blocks are
secure with proper electrical continuity. If wiring is
correct and all terminals have continuity, check for 24V
across terminals 1 and 2. If encoder has 24V power
and problem persists the encoder has likely failed.
Replace encoder.
203 Encoder
Encoder Channel A
is ON, Encoder
Channel B is OFF
Controller is
detecting encoder
channel A always
ON, channel B no
signal.
Controller is receiving a constant signal from channel A
(blue terminal block #3) and no signal from channel B
(blue terminal block #4). Verify encoder wiring as
referenced above and ensure all terminal blocks are
secure with proper electrical continuity. If wiring is
correct and all terminals have continuity, check for 24V
across terminals 1 and 2. If encoder has 24V power
and problem persists the encoder has likely failed.
Replace encoder.
204 Encoder
Encoder Channel A
is ON, Encoder
Channel B is ON
Controller is
detecting encoder
channel A and
channel B always
ON.
Controller is receiving a constant signal from channel A
(blue terminal block #3) and a constant signal from
channel b (blue terminal block #4). Verify that encoder
ground (blue terminal block #2) is secure with proper
electrical continuity at all terminations. If wiring is
correct and all terminals have continuity, check for 24V
across terminals 1 and 2. If encoder has 24V power
and problem persists the encoder has likely failed.
Replace encoder.
