CarSense202™
Single Piece Vehicle Motion Detector
Instruction Manual
The CarSense202 is a compact, single-piece vehicle motion detector that operates by detecting changes
in the earth’s magnetic field that occur near the probe with a fixed detection range of 12 feet at a
minimum speed of 5 mph. The CS202 will only detect a moving vehicle and will not detect a stationary
vehicle. The CS202 may be used as a free exit sensor to allow gates to open and guests to exit without
the use of a key fob or passcode. The CS202 may also be wired to notify a home automation system or
security system that a vehicle is moving down a driveway. This vehicle motion detector is available in 50,
100, or 150 foot lead lengths.
Cautions and Warnings
The CS202 is designed to detect moving vehicles. It is not suitable for use as a vehicle
presence detector such as a reversing loop for a gate or door.
The CS202 detects ferrous metals. It will not detect aluminum, but will detect any
moving ferrous metallic object.
The probe must be stationary to function properly.

IMPORTANT: EARTH GROUND CONNECTION
The CS202 contains transient protection devices to guard the sensitive electronic circuitry from damage
and false triggering due to electrical transients caused by lightning or other sources. Always provide a
good earth ground. An 8’ copper rod or metal cold-water pipe provides a sufficient earth ground.
When using AC power, connect the CS202 green common relay and earth ground wire to the operator.
When using DC power, connect the CS202 black power (–) wire and the operator’s ground, common
or power (–) lead to the earth ground.

Installation
Read the following list of tips prior to beginning the installation process.
This will save significant time in the long run.
•The detector’s sensitivity is a function of speed and mass. The detection distance for a moving,
average size car or truck is approximately 12 feet at a speed of 5 mph. At higher speeds,
detection distance can exceed 12 feet as noted below.
•The detector is sensitive to minute changes in the magnetic field around the probe.
Power lines, transformers, and other electrical devices located in the vicinity of the probe
that produce transients could cause disturbances in the magnetic field that may result in
triggering the detector. Avoid installation of the probe near these devices.
•Do not install the probe or lead wire near or parallel to:
•Low voltage lighting wires or in-ground power lines
•Telephone lines or intercom systems
•Electric motors or control relays
•Overhead power lines, transformers or underground power lines
•Cell phone towers, TV towers or communications links
•Moving metal flagpoles, fences, gates or horses with metal shoes
•Do not mount on any moving surface, such as bridges or walkways that may vibrate under traffic.
The probe must always be installed in such a way that it remains completely motionless.
Any movement will cause the probe to trigger.
•Probes are available in various cable lengths, when possible select the appropriate cable length
for the installation. If it is necessary to extend the cable length (maximum 900’), use a
high-quality lead-in cable suitable for direct burial and a high quality, watertight cable splice
to prevent moisture from entering the cable causing false triggering. Lead-in wire is available
from EMX.
•When there is a high incidence of damage from burrowing animals or other potential damaging
activities, it is recommended that the cable be placed in plastic conduit (1.5” internal diameter).
Damage to the cable jacket may allow moisture to enter the cable causing false triggering. When
placing the probe in plastic conduit, use foam or tape to assure that the probe does not move or
vibrate. It is recommended that the conduit be sealed to prevent water from collecting in it.

Installation Methods
Adjacent to Roadway (Recommended Method)
In a Roadway
1. Temporarily place the probe parallel to the
roadway (driveway) in the desired location.
1. Position the probe in the center of the
roadway, perpendicular to the direction of
traffic. The probe should be located at a
minimum of 2” deep in concrete or
asphalt.
•If installing the probe prior to paving a hot
asphalt roadway, the CS202 and its lead
cable need to be insulated. A common
method to do this would be to dig a small
trench and bury the probe and lead cable
in 4” of sand prior to paving. (DO NOT
APPLY HOT ASPHAULT DIRECTLY
AGAINST PROBE AND LEAD CABLE!)
•If installing the probe in concrete,
make sure it is installed above the rebar.
•The probe may be positioned prior to
paving or a cut may be made in the
finished pavement for installation.
2. Connect the power, output relay contact and earth ground to the intended equipment.
(Reference EARTH GROUND CONNECTION in Wiring Connections.)
DO NOT EXCEED 41 VDC or 29 VAC.
3. Apply power and allow 5 minutes of warm-up for system stabilization.
4. Drive a vehicle at a minimum speed of 5 mph passed the probe and to the far side of the
roadway. Upon detection of the moving vehicle, the output relay will energize for approximately
2 seconds. Verify that the CS202 has detected the moving vehicle.
5. Bury the probe at this location approximately
8-12” deep for typical applications.
Repeat the previous sensitivity check
(step 4-5) to verify proper operation.
Installation adjacent to roadway complete.
5. Installation in roadway complete.
For instances of high pedestrian traffic, heavy animals or heavy vehicles, bury the
probe 24” deep to prevent false triggering in either installation method.

Troubleshooting
Warranty
EMX Industries, Inc. products have a warranty against defects in materials and workmanship for a period
of two years from date of sale to our customer.
Symptom
Possible Cause
Solution
False triggering
Electrical disturbances
Damaged probe cable
Moisture in probe cable
Movement in the probe’s
environment
Dirty or noisy power supply
Lightning
1. Disconnect from operator power supply,
temporarily connect the red and black wires
to a 9 or 12V battery. Wait 5 minutes for the
system to stabilize. If the false triggering
stops, consider using a separate power supply
for the CS202 such as a 120 VAC to
12 VDC power converter (min. 100 ma).
2. Disconnect the relay wires and see if the false
triggering continues. If the false triggering
stops, switch the brown and green wires in the
operator and/or add earth ground connection
to COM input in operator. Verify that the
earth ground is connected securely. If the
connection is not secure, reconnect the earth
ground and retest the system.
3. Inspect the area around the probe to see if
any ferrous metal objects may be subject to
any movement. These may include fences,
flagpoles, signs, etc. Other possible causes are
electrical power lines, electric motors, invisible
dog fences, low voltage lighting and
high-power lighting.
No detection
Minimum 5 mph
Bad wire connection
Faulty power connection
Failed relay
1. Disconnect the output contacts from the
operator.
2. Connect a digital multi-meter, set to read
ohms, to the CS202 internal relay COM and
NO contacts. The meter should read open
(infinity). Move a metal tool over the length of
the probe. Verify that the meter reads less
than 10 ohms. If the meter reads more than
10 ohms, the CS202 is defective.
3. Check the supply voltage using a digital
multimeter. Verify the voltage is 9-41 VDC or
6-29 VAC. If voltage is present and there is still
no detection, the CS202 is defective.
