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 (CS303-

DB) 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.

Operation (continued)

Set the Configuration Selector Switch

Presence detection is determined by the settings programmed to the CS303-DB / CS303-FP connected. Refer to the CS303 Operating Instructions when installing the sensor(s) (CS303-DB

/ CS303-FP) to determine sensor settings appropriate for your application.

Relay2: Inactive

Discrete Relays

While operating in Discrete Relays mode, Relay1 will activate and remain active while a vehicle is detected by Sensor1. Relay2 will activate and remain active while a vehicle is detected by Sensor2.

AB Directional Logic

AB Directional Logic mode is capable of determining the direction of travel of a vehicle using two sensors. Two sensors are installed in the direction of travel to provide input.

If a vehicle is detected by Sensor1 and then Sensor2, Relay1 will activate and remain active while the vehicle is detected by Sensor2.

If a vehicle is detected by Sensor2 and then Sensor1, Relay2 will activate and remain active while the vehicle is detected by Sensor1.

When using the AB Directional Logic function, the sensors should be installed 1 meter (40”) apart.

Operation (continued)

Pulse on Entry

Pulse on Entry provides mode presence (Relay1) and pulse (Relay2) outputs. When a vehicle is detected by Sensor1, Relay1 will activate and remain active while the vehicle is present, Relay2 will activate for 500ms and then remain inactive.

Pulse on Exit

Pulse on Exit mode provides presence (Relay1) and pulse (Relay2) outputs. When a vehicle is detected by Sensor1, Relay1 will activate and remain active while the vehicle is present, Relay2 will be inactivate until the vehicle is undetected, then Relay2 will activate for 500ms and then deactivate.

Dual Relays

Dual Relays mode allows for the operation of both Relay1 and Relay2 by Sensor1. While a vehicle is detected by Sensor1, both Relay1 and Relay2 will be active.

Common Relay

Common Relay mode allows for the operation of Relay1 and Relay2 by both Sensor1 and Sensor2. When a vehicle is detected by either Sensor1 or Sensor2, Relay1 will remain active while the vehicle is detected, Relay2 will activate for 500ms and then remain inactive.

Invalid

While the rotary switch is set to positions 6, 7, 8, or 9, the relays will remain inactive and all three LEDs on the unit will flash on and off once per second.

Troubleshooting

Possible Cause Solution Symptom

All LEDs flash, one second cycle

Invalid rotary switch selection

Set rotary switch to a valid setting

(0-5)

Red LED flashes, relay clicks, unstable

Green and Red LEDs flash simultaneously

Poor connection for Sensor1 or

Sensor2

Insufficient supply voltage

Check and fix connection

If only one sensor is used, set rotary switch to a valid position for 1 sensor

Make sure the power supply is working correctly and properly rated according to connections table

Installation

1.

Refer to CarSense 303 Operating instructions for installation and set-up of the sensors for proper operation. All settings are stored in the sensors for stand-alone operation.

2.

CS303-L monitors the NPN outputs from the sensors and does not provide the ability to change sensor (CS303-DB / CS303-FP) settings.

3.

When using the AB Directional Logic function, the sensors should be installed 1 meter (40”) apart in the axis of travel.

4.

When wiring the sensors to the CS303-L: a.

The brown wire from both sensors goes to pin 11 on the CS303-L b.

The blue wire from both sensors goes to pin 10 on the CS303-L c.

The white wire from one sensor goes to pin 8 (Sensor1 Input) on the CS303-L d.

The white wire from the other sensor goes to pin 7 (Sensor2 Input) on the

CS303-L e.

Protect RED and GREEN wires from the sensor using electrical tape or other suitable electrical insulation
