Rack Mount Loop Detectors -ORACLE 2E SERIES – DUAL CHANNEL TS-1 Type
The ORACLE “ENHANCED” series meet or exceed
all applicable requirements in NEMA TS 1-1989 and NEMA TS2-2003.
New Features
LCD View Screens: The Loop Frequency, ΔL/%,
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.
