Before You Start ...
Please read the instructions completely before you begin the installation.
Terms and Definitions:
•
METAL OBJECT: anything that is made of iron-based metal, from a child's toy to a car or truck.
•
SENSOR: the magnetic device inside the waterproof tube that detects METAL OBJECTS in motion.
•
MAGNETIC FIELD: an area around the SENSOR where metal in motion can be detected.
•
MAGNETIC DISTURBANCE: a change in the MAGNETIC FIELD which lets the SENSOR know that it
needs to send a signal to the gate opener to open the gate.
•
RANGE: the distance from the SENSOR in which a MAGNETIC DISTURBANCE can be detected in the
MAGNETIC FIELD.
•
RANGE ADJUSTMENT: the RANGE is adjustable from a 3 to 12 foot* radius by tuning the ADJUSTMENT
POTENTIOMETER (POT) on the RANGE ADJUSTMENT CONTROL BOARD (shown on page 5). Within
this RANGE, the closer you get to the SENSOR, the less metal and motion an object needs to cause a DIS-
TURBANCE in the MAGNETIC FIELD.
CAUTION This principle explains why a child's tricycle, bicycle and other metal objects moving close to the
SENSOR may have the same DISTURBANCE as a car or truck at a greater distance, and can cause the gate
to open.
•
WIRE CLAMP: a device which provides a secure and weatherproof opening for the cable from the SENSOR
to be brought into a control box (see Parts Identification on cover).
•
DOUBLE SPADE CONNECTOR: a wire connector which allows the connection of two wires to be connect-
ed to a single terminal (see Parts Identification on cover).
How the VEHICLE SENSOR works:
•
When a metal object such as a car, truck or motorcycle in motion disturbs the MAGNETIC FIELD around the
SENSOR, a signal is sent to the automatic gate opener's control board, signaling it to open the gate.
•
The metal object must be in motion to disturb the MAGNETIC FIELD, thus activating the gate opener.
How the VEHICLE SENSOR's RANGE ADJUSTMENT works
•
The RANGE distance can be adjusted from a 3 to 12 foot* radius from the SENSOR.
•
The potentiometer varies the sensitivity range of the SENSOR to avoid unwanted moving metal objects from
activating the gate opener, such as: other moving gates; metal play equipment; garage doors; other vehicular
traffic; etc.
•
With the RANGE adjusted to the maximum of 12 feet*, a large metal object moving slowly will be detected
12 feet* from the SENSOR, while a small metal object moving slowly might not be detected at the same
distance. As you move closer toward the SENSOR, the small moving metal object will at some point cause a
DISTURBANCE in the MAGNETIC FIELD and activate the gate opener.
Placement of the SENSOR:
*
Range distance is approximate and will vary due to outside interference, type of soil, vehicle mass, speed, etc.
