CarSense 303-L™ Operating Instructions 1
Document no. 10310404 Revision 1.6 5-30-17

Cautions and Warnings

CE REQUIREMENT: Use CE rated power supply for CE compliance providing
suppression as specified by EN61000-4-5.

Not to be used in safety applications.

IMPORTANT:

This product is an accessory or part of a system. Always read and follow the
manufacturer’s instructions for the equipment before connecting this product. Comply
with all applicable codes and safety regulations. Failure to do so may result in damage,
injury, or death.

WARNING:
DO NOT INSTALL THE SENSOR DIRECTLY INTO HOT ASPHALT, see installation section

WARNING:

Always use photoelectric protection when using the CS303 as a closing
detector on a parking arm operator to prevent accidental closing on a car.

Product Overview

The CarSense 303 Logic Interface (CS303-L) works with CarSense 303 Direct Burial (CS303­DB) or CarSense 303 Flat Pack (CS303-FP) magnetoresistive sensors. Once the sensors
have been programmed using the CarSense 303 Controller (CS303-C-1), the sensors store
the settings and can operate independent of the controller.

The Logic Interface allows one or two sensors to be connected and provides 6 different
logic functions and two sets of relay outputs, one form A and one form C.

These functions include:

• AB Directional Logic

• Pulse on Entry

• Pulse on Exit

• Common Relay operation

• Discrete Relay operation

• Dual Relay operation

For more information regarding these functions and how they work, see page 4

Operation

Power Up

Upon power up the detector initializes: all three LEDs will flash on, then off. The green

LED indicates that the detector is powered and operational. Relay1 and Relay2 LEDs

indicate when Relay1 or Relay2 is activated, respectively.

Note that the sensor must be installed and programmed using a CS303-C-1 prior to

connection to the CS303-L. The CS303-L only monitors the sensors’ NPN outputs and

cannot be used to change operation settings in the sensor.
