System Description
CIRCUIT OPERATION
[Example]
Aiming switch ``0''
+When the aiming switch is set to ``0'', the motor will not start.
This is because the power terminals are positioned at the non-
conductive section of the sensor's rotary unit.
Aiming switch ``0''®``1''
+When the aiming switch is moved from ``0'' to ``1'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The headlamps will then move
in the ``DOWN'' direction.
+The motor continues to rotate while the rotary unit of the sen-
sor moves from point A to point B.
+The power terminals will then be positioned at the nonconduc-
tive section, disconnecting the power to the motor. The motor
will then stop.
Aiming switch ``1''®``0''
+When the aiming switch is moved from ``1'' to ``0'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The motor will rotate to move the
headlamps in the ``UP'' direction.
+When the rotary unit of the sensor moves from point B to point
A, the motor will stop.
