DCS Actuator Rod Does Not Move
Use this flow chart if the DCS Actuator Rod does not
move or if the DCS displays error code E09 (Hall Sensor
Error). Reference Wiring Diagram, page 68.
Turn power switch to OFF. Remove the blue shroud behind the DCS Control.
Ensure you have a good 12V battery installed. Disconnect the actuator motor
wires and signal cable from the DCS Control. Connect a multimeter between
the blue and brown wires on the DCS Control. Turn the power switch to ON.
Measure the voltage (DC) within 10 seconds of turning the power on. Does it
measure at least 3.0 VDC?
Within 10 seconds of turning the power switch to ON (while connected to
a good battery), measure the voltage (DC) between the red and black
wires on the actuator signal cable coming from the DCS Control. Does it
measure at least 10 VDC?
Reconnect the actuator motor wires and signal cable from the actuator to
the DCS Control. Turn the power switch to ON. Does the DCS Control
display the Run Screen within 5 seconds?

Connect the blue and brown wires on the
BLUE
BROWN
actuator to a good 12VDC battery. First try with
the blue wire on positive post and brown wire
on negative post. If the actuator rod does not
12V
move, put the blue wire on the negative post
and the brown wire on the positive post. Does
the rod move in either case?
