Vehicle detectors are designed to be used in conjunction with a formed loop of wire that is buried in the pavement. When charged with electrical current, the loop wire produces a magnetic field that is changed by the presence of a vehicle. The vehicle detector measures the change in inductance and sends an electrical signal to operate equipment. 21/2' x 6' with 20' lead in.

Two Models Cover ALL Voltages: LMA-1250-LP operates on 12VDC, 24VDC, and Low Power. LMA1250-HV operates on 120VAC and 240VAC

DEFLECTOMETER ™:
The front panel 7-segment LED DEFLECTOMETER™ provides visual feedback and assistance for setting the correct sensitivity, reading the frequency of the loop, reporting Loop Faults, and indicating Delay & Extension Timing functions.

The LM series of Loop Detectors takes vehicle detection one step further. They not only indicate vehicle presence with great accuracy and reliability, but also monitor the condition of the loop for diagnostic purposes.

The LM302 Series meet or exceed all standards specified in NEMA publication TS 1-1989 part 15 (Inductive Loop Detectors)

Detection Features
Automatic Tuning: No manual tuning is required.

Environmental Tracking: Ensures reliable operation by continuously adjusting for changes in ambient conditions.

15 Levels of Sensitivity: Allows users to fine tune the Loop Monitor to their application.
Four Loop Frequencies and Sequential Scanning: Together, these features greatly reduce the incidence of cross-talk.

Three Selectable Modes:

• Pulse: For counting and volume.
• Short Presence: For normal detection.
• Long Presence: For sites where loops may be occupied for extended periods of time.

Diagnostic Features

Color-Coded, Separate LEDs for Detect & Fault Indication: Eliminates the confusion encountered with other detectors that use only one LED to display both faults and detection. The Yellow Fault LED works independently from the Red Detect LED to display the type of fault: Short, Open or 25% change of inductance. Each type of fault is indicated by a unique sequence of flashes allowing the user to diagnose loop failures at a glance.

Fault Memory: Records previous fault information. If a problem self- heals, the LM302 will resume normal operation. The contents of the memory will be displayed on the Fault LED. This feature can be used to isolate the source of intermittent loop failures.

Options: Optically Isolated Solid State Outputs Delay and Extension Timing

Specifications

Power Supply: 15 VAC +20%, 60 Hz, 3 W max.

Delay and Extension Timing (LM302t):
Delay times up to 63 seconds in 1 second increments, and extension times up to 15.75 seconds in 0.25 second increments may be selected by setting the appropriate front panel DIP switches to the ON position. The DETECT LED indicator will flash at a 2 Hz rate while the delay timer is running and at a 4 Hz rate while the extension timer is running.

The ORACLE “ENHANCED” detectors not only indicate vehicle presence with great accuracy and reliability, but also incorporate a complete built-in loop analyzer for optimum detector set-up and loop diagnostic purposes.

New Features

LCD View Screens: The Loop Frequency, -ΔL/L%, Loop Inductance, DEFLECTOMETER™ Pie Graph, DEFLECTOMETER™ Numeric Optimizer, DEFLECTOMETER™ Streaming Graph, Frequency Stability Graph, Sensitivity Level, Mode of Operation, and Vehicle Counting Accumulator can be viewed on the front panel LCD for each channel simultaneously.

DEFLECTOMETER™ Pie Graph & Numeric Value Indictor: While the DEFLECTOMETER™ pie graph displays an instantaneous indication of the current Call strength, the Streaming Graph display graphically shows the Call strength over time. The horizontal axis represents a six second interval. The vertical axis represents Call strength. The graph streams when there is a Call present.

Frequency Stability Graph: The frequency stability graph provides the capability to analyze each frequency level to ensure proper selection of the nominal loop tuning frequency. The XY graph displays detector frequency samples with respect to the reference.

A variation from the center of the graph depicts frequency instability on the channel. Basically a thin smooth graph offers a more optimum frequency selection over a thick uneven line.

Paired Channel Functions:
Directional Logic and 3rd Car Logic: When both of the paired channels have detection in Directional Logic mode, the last channel to have detection will output a CALL until the detection for the last channel ends, even if the detection ends for the first channel. This feature is intended to be used in freeway ramps for wrong way detection and left turn lanes where other movements in the intersection tend to clip the detection zone of the left turn lane. 3rd Car Logic provides a Call output when both channels are in the Call state. 3rd Car Logic is typically used in left turn queues to provide logic for Protected-Permissive movements.

Enhanced Features

Programmable Navigation: The ORACLE “ENHANCED” Series provides a flexible and simple programming process via the front panel bidirectional toggle switches. Moving through the menu choices has never been easier. The new QuikSet mode navigates to commonly used menu items quickly.

Loop Fault History Log: For each channel, the LCD screen can display the last 25 loop fault conditions and power events.

Loop Inductance Display Indicator: In the “Induct” display mode the LCD screen displays the equivalent system loop inductance (loop and lead-in inductance) within the range of 20 to 2500 micro Henries.

High Intensity Front Panel Back Lighting: The Liquid Crystal Display (LCD) incorporates a white LED backlight. The backlight is energized when any switch is actuated and remains on for 2 hours after the last switch actuation. The backlight improves visibility in poor lighting conditions.

Variable Character Channel ID: Up to five characters or numbers can be selected to identify each channel of detection.
