Pic #48 Electro-Pneumatic Schematic for One Arm Assembly
When
the vehicle is being pulled through the wash, it makes contact with and pushes the wheel, because of the
rotation of the wheel
(CCW for D/S and CCW for P/S)
and because of its geometry, the
PRIMARY ARM
leaves its
resting position, releasing the
PRIMARY LIMIT SWITCH
(see Picture #41) turning
OFF
the solenoid valve,
releasing the air slowly from the
SECONDARY ARM.
