Digital Linear Actuator (DLA)
Energizing the bi-directional digital linear actuator coils
in the proper sequence, causes the threaded shaft to
move out of, or back into the rotor, in precise linear
increments. When power is removed, the actuator
shaft remains in position. The DLA must initialize (fully
extend) to move the throttle plate to the closed
position, and partially open for starting. Correct
adjustment of the DLA is critical to achieve the full
range of throttle plate movement. See Adjustment
Procedure.
