CIRCUIT OPERATION
IExample]
Aiming switch "0"
o When
the aiming switch rs set to "0",

2 3 Aiming
switch "O" --
"1"
o When
the aiming switchis moved from "0"
to "1",
power is
applied to the motor through the relay
operated by the
sensor's conductive secton. The
headlamps
will then move
in lhe "DOWN"
direction.
o The
motor continues lo rotate while the rotary unit
of the
sensors moves from point
A to point
B.
o The power
terminals will
lhen be positioned
at the noncon-
ductive seclion, disconnecting the power
tothe motor.
The
motor lhen slops.
Aiming switch "1"
