Fig. 5-1 Auto Sweep Motor Circuit (Horizontal air defl ectors)
● Fig. 5-1 shows the Auto sweep motor drive circuit; the signals shown in Fig. 5-2 are output from pins
– of the micro computer.
Fig. 5-2 Micro computer Output Signals
● As the micro computer’s outputs change as shown in Fig. 5-2, the core of the auto sweep motor is
excited to turn the rotor. Table 5-1 shows the rotation angle of horizontal air defl ectors.
