Horizontal air deflectors
As the micro computerÕs outputs change as shown in Fig.4-4, the core of the auto sweep motor is excited
to turn the rotor. Table 4-2 shows the rotation angle of horizontal air deflectors.
Table 4-2 Auto sweep otor Rotation
Horizontal air deflectors
The air deflectors are driven by the stepping motors, which are instructed by the micro computer .
The air deflectors on the left and right are each driven by two stepping motors.
The stepping motors and main unit are connected via relay connectors. The air deflectors will not operate
unless the relay connectors are connected: Securely connect the relay connectors identified by colors
when attaching the panel.
Before removing the panel for servicing, be sure to disconnect the relay connector to protect the lead
wires.
