Single Cut Magnetoresistive Vehicle Detector

Instruction Manual

The Loop Replacement System (LRS) features advanced 3-axis, magnetoresistive sensing technology.

The small size of the LRS allows for easy installation in pavement with a single saw cut. It provides cost

savings on labor and materials when compared to the multiple cuts and corner reliefs required for the

installation of inductive loops. The sensor measures the Earth’s magnetic field and responds

to disturbances caused by ferrous objects. Three sensing elements provide magnetic field measurement

in the X, Y and Z axis, improving detection sensitivity. The LRS flat pack (FP) and direct burial (DB) sensors

are also suitable for above ground installations, making them ideal for use in confined areas or hidden in

non-ferrous architectural components for security purposes. The LRS’ exciting new technology provides

a high-sensitivity, compact and cost-effective solution for reliable vehicle detection.

NOTE: When power is applied to the LRS-C1 controller and the LRS-FP or DB sensor is connected,

the settings on the controller will be sent to the sensor. The sensor stores these settings even when

disconnected from the LRS-C1. However, the controller is required to program and recalibrate

the sensor.

Installation Read the following list of tips prior to beginning the installation process. This will save significant time in the long run.  Every time the settings are changed on the LRS-C1 or the sensor is moved, press the RESET button on the LRS-C1.  The LRS-FP and DB sensors are sensitive to minute changes in the magnetic field around them.
PAGE 5
TIP: The LRS-FP and DB sensors have the ability to detect in 3 dimensions (X, Y, Z axis). In most applications, all three axes should be switched on (DIP switch 1, 2, and 3).  Note that the LRS-FP sensor allows for the best implementation of the axis settings. The installer knows the direction of all axes because of the flat pack’s fixed orientation within the saw cut. (See the axis diagram in the photo below.
PAGE 6
LRS-DB Installation For vertical installation, drill a 7” x 1.5” hole in the surface with a 5/16” x 2” deep saw cut exiting the cutout for the communications /power cable. Backer rod should be placed at a minimum of every 10-14”. Hard epoxy pavement sealant should then be used to fill the cable and sensor cavities. Make sure pavement sealant does not extend above roadway surface. Y axis Y axis Note: The Y axis is always the direction of the cable.

Troubleshooting Symptom No detection Red LED on constantly (stuck in detection mode) or ULTRAMETERTM display shows a value when no car is present No green LED, red LED or ULTRAMETERTM display on EMX Industries, Inc. Document No.10310204 Rev 1.1 Possible Cause Sensitivity set too low Solution With a vehicle within the desired proximity, observe the ULTRAMETERTM display to find the minimum sensitivity required for detection.

Symptom Green LED flashes half second on, half second off, “E” “1” flashes on display Possible Cause Communication failure Solution 1. Check the communications and power wiring to the sensor. 2. Cycle power to the control unit and sensor. Green and red LEDs flash simultaneously, “E” “2” flashes on display Insufficient supply voltage 1. Make sure the power supply is working correctly and properly rated (see Wiring Connections).
