CIRCUIT OPERATION
[Example]
Aiming switch
"0"

• When theaiming switchisset to"0", themotor willnotstart.
This isbecause thepower terminals arepositioned atthe
nonconductive sectionofthe sensor's rotaryunit.

Aiming switch
"0"

"1"

• When theaiming switchismoved from"0"to"1", thesen-
sor's conductive sectionactivates therelay. Power issup-
. plied through therelay tothe motor. Theheadlamps will
then move inthe "DOWN" direction.
• The motor continues torotate whiletherotary unitofthe
sensor movesfrompoint Ato point B.
• The power terminals willthen bepositioned atthe noncon-
ductive section, disconnecting thepower tothe motor. The
motor willthen stop.
