CarSense 303-L™ Operating Instructions 2
Document no. 10310404 Revision 1.6 5-30-17
CE REQUIREMENT: Use CE rated power supply for CE co pliance 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 C 303 as a closing
detector on a parking arm operator to prevent accidental closing on a car.
Product Overview
The Car ense 303 Logic Interface (C 303-L) works with Car ense 303 Direct Burial (C 303-
DB) or Car ense 303 Flat Pack (C 303-FP) magnetoresistive sensors. Once the sensors
have been programmed using the Car ense 303 Controller (C 303-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 C 303-C-1 prior to
connection to the C 303-L. The C 303-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-D / CS303-FP
connected. Refer to the CS303 Operating Instructions when installing the sensor(s) (CS303-D
/ CS303-FP) to determine sensor settings appropriate for your application.

Discrete Relays
While operating in Discrete Relays mode, Relay1 will activate and remain active while a
vehicle is detected by ensor1. Relay2 will activate and remain active while a vehicle is
detected by ensor2.
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 ensor1 and then ensor2, Relay1 will activate and remain
active while the vehicle is detected by ensor2.
If a vehicle is detected by ensor2 and then ensor1, Relay2 will activate and remain
active while the vehicle is detected by ensor1.
When using the A Directional Logic function, the sensors should be installed 1 meter (40”)
apart.

Document no. 10310404 Revision 1.6 5-30-17
Operation (continued)
Pulse on Entry
Pulse on Entry provides mode presence (Relay1) and pulse (Relay2) outputs. When a
vehicle is detected by ensor1, 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 ensor1, 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 ensor1. While
a vehicle is detected by ensor1, both Relay1 and Relay2 will be active.
Co on Relay
Common Relay mode allows for the operation of Relay1 and Relay2 by both ensor1
and ensor2. When a vehicle is detected by either ensor1 or ensor2, 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.

1. Refer to Car ense 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. C 303-L monitors the NPN outputs from the sensors and does not provide the
ability to change sensor (C 303-DB / C 303-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 C 303-L:
a. The brown wire from both sensors goes to pin 11 on the C 303-L
b. The blue wire from both sensors goes to pin 10 on the C 303-L
c. The white wire from one sensor goes to pin 8 ( ensor1 Input) on the C 303-L
d. The white wire from the other sensor goes to pin 7 ( ensor2 Input) on the
C 303-L
e. Protect RED and GREEN wires from the sensor using electrical tape or other
suitable electrical insulation
