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 LRS as a closing detector
on a parking arm operator to prevent accidental closing on a car.
Product Overview
The Loop Replacement System Logic Controller (LRS-LC) works with LRS Direct
Burial (LRSDB) or LRS Flat Pack (LRS-FP) magnetoresistive sensors. Once the
sensors have been
programmed using the Loop Replacement System Controller (LRS-C1), 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
Specifications
NOTE: Refer to LRS Operating Instructions for operation and installation
of controller
and sensor.
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 LRS-C1 prior to connection to the LRS-LC. The LRS-LC only monitors the sensors’ NPN outputs and cannot be used to change operation settings in the sensor.
Set the Configuration Selector Switch
Presence detection is determined by the settings programmed to the LRS-DB /
LRS-FP connected. Refer to the LRS Operating Instructions when installing the
sensor(s) (LRS-DB / LRSFP) 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 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.
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.
Controls and Indicators
Connections
NOTES:
- Refer to Operator Instruction for power and relay/control connections
- Protect RED and GREEN wires from the sensor using electrical tape or other suitable electrical insulation
Troubleshooting
Installation
- Refer to LRS-C1 Operating instructions for installation and set-up of the sensors for proper operation. All settings are stored in the sensors for stand-alone operation.
- LRS-LC monitors the NPN outputs from the LRS sensor and does not provide the ability to change sensor (LRS-DB / LRS-FP) settings.
- When using the AB Directional Logic function, the sensors should be installed 1 meter (40”) apart in the axis of travel.
- When wiring the sensors to the LRS-LC:
a. The brown wire from both sensors goes to pin 11 on the LRS-LC
b. The blue wire from both sensors goes to pin 10 on the LRS-LC
c. The white wire from one sensor goes to pin 8 (Sensor1 Input) on the LRS-LC
d. The white wire from the other sensor goes to pin 7 (Sensor2 Input) on the LRSLC
e. Protect RED and GREEN wires from the sensor using electrical tape or other suitable electrical insulation
