Loop Detectors
a)
2 / 4 Channel, general use.
Provide the following functions or indications on LCD view screen on a per channel basis: loop
frequency, percent change, inductance, stability, sensitivity, operation mode, counting
accumulator, etc.
A real-time pie graph which assists in determining the optimum sensitivity setting shall be
provided.
A streaming graph shall show 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.
A stability graph provides the capability to analyze each frequency level to ensure proper
selection of the nominal loop tuning frequency. A variation from the center of the graph depicts
frequency instability on the channel.
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 left turn lanes where
other movements in the intersection tend to clip the detection zone.
Optional, accurate count mode produces a secondary output in addition to the primary CALL
output for each vehicle entering the loop zone. Loop configurations range from a single loop to
eight loops connected together in series. The Count Accumulator screen can be used to view
the totals.
For each channel, the LCD screen can display the last 25 loop fault conditions and power
events.
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 microHenries. It can also display
the percentage of inductance change during the CALL state.
Page 5
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.
Up to five characters or numbers can be selected to identify each channel of detection.

2 /4 Channel, diagnostic.
The LCD screen displays the actual loop operating frequency for each channel. Eight (8)
selectable loop frequency settings are available per channel.
A bar graph displayed on the LCD allows setting the sensitivity [-∆L/L(%)] for any loop / lead-in
situation. Nine (9) selectable sensitivity levels are available per channel, plus settings for
Continuous-Call and Channel-Off.
The loop oscillator is disabled when in the Continuous-Call or Channel-Off state. Each state is
indicated by a unique display on the LCD.
Each channel’s Call Delay is adjustable from 0 to 255 seconds in one-second steps. Call Delay
time begins when a vehicle enters the loop detection zone.
Each channel’s Call Extension is adjustable from 0 to 25.5 seconds in 0.1-second steps.
Extension time begins when the last vehicle clears the loop detection zone.
Each channel can be placed in either presence or pulse mode. Presence mode provides a
minimum Call hold time of at least four (4) minutes (regardless of vehicle size) and typically one
to three hours for an automobile or truck.
Page 6
A single output Pulse of 125 ±10 milliseconds duration is generated for each vehicle entering the
loop detection zone. Each detected vehicle is instantly tuned out if it remains in the loop detection
zone longer than two (2) seconds.
Each channel’s Max Presence timer is adjustable from 1 to 999 seconds in one-second steps,
plus OFF. The Max Presence function is used to limit presence time by automatically resetting a
channel.
Options:
When this option (1) is enabled (On), the LCD screen displays the total loop inductance (actual
loop inductance plus lead-in inductance) in microhenries.
When this option (2) is enabled (On), the LCD screen displays the percentage of inductance
change (-∆L/L value) during the Call state. The detector holds the peak -∆L/L value for a period
of two (2) seconds.
When this option (11) is enabled (On), an audible signal will be activated whenever vehicles are
in the detection zone. The audible signal indicates occupancy of the loop detection zone.
All options are automatically disabled five (5) minutes after the last switch activation or on loss of
power.
Mechanical / Electrical:
Less than or equal to 7.0 oz (199 gm.).
4.50 inches high x 1.12 inches wide x 6.875 inches deep. Handle adds 1.00 inch to depth
measurement.
Complies with NEMA Environmental requirements.
Circuit boards are 0.062 inch thick FR4 material with 2 oz. copper on both sides and plated
through holes. Circuit boards and components are conformal coated with polyurethane.
10.8 to 14 VDC, 100 mA maximum, 40 mA during normal operation.
Loops, 20 to 2500 microhenries. All transformer isolated, tolerates a shorted loop.
Lead-in up 5000 feet with proper feeder cable.
Application of a 30 millisecond low state (0 to 3 VDC) to pin C resets all channels.
The LCD backlighting illuminates whenever any pushbutton is pressed. The backlighting and
LEDs will extinguish five (5) minutes after the last actuation of any pushbutton.
Each channel has a high-intensity red light-emitting-diode (LED) to indicate a Call output, Delay
Timing, Extension Tiiming, or failed loop.
The detector automatically tunes and is operational within two (2) seconds after application of
power or after being reset. Full sensitivity and hold time require 30 seconds of operation.
Page 7
If the total inductance of the channel’s loop input network goes out of the range specified for the
detector, or rapidly changes by more than ±25%, the channel will immediately enter the Fail-Safe
mode and display
If the detector is reset, or power is momentarily lost, the detector will retune if the loop
inductance is within the acceptable range.
The Fail-Safe mode generates a continuous call in both Presence Mode and Pulse Mode.
Pressing any two of the front panel switches simultaneously will display all symbols and
messages on the LCD screen.
Card Edge Connectors:
2 x 22 contact edge card connector with 0.156 inch (0.396 cm.) contact centers. Key slots located
between pins B/2 & C/3, E/5 & F/6, and M/11 & N/12.
Field effect transistors (FETs) are used for outputs. 30 VDC maximum drain to source. 50mA
maximum current. 0.1 VDC maximum transistor saturation voltage. The output transistors are
protected by 33 volt Zener diodes connected between the drain to souce.

BIU Module. RENO (similar to Eberle)
General Description: The circuit card consists of a front communications hookup, a display
section and handle. A glass epoxy circuit board contains the communications and interface
components. The back of the Bus Interface Unit (BIU) has a 29 pin card edge that fits into a
standard TS2 interface.
The BIU complies with Section 8 and all other applicable sections of the NEMA TS2-2003
Standard. It performs its specified functions under the environmental conditions set forth in
Section 2 of the standard.
Operates from 16 to 30 VDC. 1.25 Amps maximum (initial power application), 200 milliamps
maximum (steady state operation).
The printed circuit board is 0.062 inch thick FR4 glass epoxy material with 2 oz. copper on both
sides and plated through holes. Circuit board components are conformal coated with
polyurethane.
Size less than or equal to 4.50 inches high x 1.12 inches wide x 6.78 inches deep (including
connector, excluding handle). Weight less than or equal to 5.4 oz.
Front (Communications port and Display):
An aluminum handle on the front panel faciltates insertion and removal of the BIU into and from a
card rack. The front panel is made of 0.062” thick aluminum.
Three LEDs light to indicate Power (PWR), Transmit (TX), and Receive (RX). The first two
indicators meet the NEMA standard. In addition, the front panel has a Receive indicator lamp
which lights whenever a valid data frame is received.
The Port 1 SDLC Bus connector on the front panel of the BIU is a female, 15-pin, metal shell, Dsubminiature type with gold plated contacts. The connector is equipped with latching blocks and
mates with a male, 15-pin, D-subminiature type cable connector that is equipped with spring
latches (Amp part number 745012-1 or equivalent).
When the BIU is used in a TS2 Type 1 cabinet, the full-duplex SDLC serial data bus provides
high speed, bidirectional data exchange between the controller, the Malfunction Management
Unit (MMU), the Detector Rack(s), and the Terminals and Facilities. The bus operates at 153,600
bits per second (bps) and uses four sets of RS-485 balanced lines: Rx Data, Rx Clock, Tx Data,
and Tx Clock.

Logic Ground
The TS2 Standard specifies 24 V logic pin assignments for the rear connector of the BIU as
follows: eight inputs, four opto-isolated inputs, 24 remappable input / outputs, 15 outputs, and
four address-select inputs. The isolated inputs are intended to be used with pedestrian detectors
and remote interconnect signals. All outputs (Eberle) are rated at 150mA continuous sink
Page 10
current. Each output provides a 500mA typical current limit. Outputs are rated to 50 volts and
utilize a voltage clamp for inductive transient protection.
The BIU has four optically isolated inputs for use with pedestrian pushbuttons and remote
interconnect. These inputs provide minimum electrical isolation of 10 MOhm, minimum electrical
breakdown of 1000 VAC, and a nominal input impedance of 5 kOhm.
The four address-select inputs provide 16 BIU addresses, which are normally set by jumpers on
the backplane. The TS2 Standard specifies the I/O mapping for eight of the addresses. Once one
of the eight addresses has been set, all I/O pins of the backplane and the BIU are fully defined,
thus allowing standardized cabinet wiring and simple menu-driven programming of the controller.
Operation of the SDLC bus is completely transparent to the user. BIU’s 1 through 4 are
designated for Terminals and Facilities; BIU’s 9 through 12 are for Detector Racks.

Advanced Model (Phase Selector)
Page 25
The PS (phase selector) meets the basic model specifications described above and adds
additional features. Each model would have an application at various locations in the field,
needing classification or transit vehicle features, or not.
Two communication ports may be provided on the card. The front connection will be via a 6 pin
DIN connector, and the back connection will be over the TS 2 communications bus. The back
connection is an optional. Either communication port will allow direct setting of the range via
software.
A D shell connector shall be provided on the front panel for confirmation lights, auxiliary detector
inputs and auxiliary detector power. A wiring harness shall be provided with each unit. Other I/O’s
with respect to this connector are as follows:
Green sense wires (110 or 24 VDC) will monitor the state of the controller during and just after
preempt, to record statistics on how effective the preemption was in delivering the desired green.
This information will be logged along with other information about each preempt event.
A confirmation light output will be provided compatible with the 24 VDC logic system used in the
terminal facilities. An output will be made available on a per channel basis on the front auxiliary
connector.
No NEMA outputs from the PS are needed.
The PS should have the ability to provide gating of a preempt request with respect to an external
input. This feature should be available during low or high priority requests.
The PS’s card edge connector includes primary infrared detector inputs and power outputs. Four
(4) additional detector inputs per channel will also be provided on a front panel connector.

Railroad. This section to be developed
C. Transit
D. Maintenance and Emergency Vehicles (optical signal source)
1.
DATA ENCODED EMITTER & SWITCH UNIT
To preempt a traffic signal each vehicle needs one or more emitters (bright flash-tube lights). The
lights are designed to transmit optical energy in a narrow beam to a detector mounted somewhere
near the signalized intersection. The control unit for the light is further specialized to provide a
precise flash rate (about 14 Hz) for an emergency vehicle, another rate (about 12 Hz) for a probe
vehicle and the last (about 10 Hz) for a transit vehicle. It is also possible to further identify the
vehicle (engine #, bus #, etc.) by transmitting a digital signature that "rides" on the 10-14 Hz carrier.
Page 28
2.
DATA ENCODED EMITTER
The vehicle emitter will generate an infrared signal consisting of a series of intense flashes from a
single light source. Modulated on top of this signal shall be digital vehicle identification. The
energy output per flash from the unit will be 0.84 Joules. A 25 ft. (7.5 m) installation cable shall be
attached to the unit.
Power for the emitter will come from a source (vehicle battery) of from 10-16 VDC. There will be
an integral in-line fuse holder and a quick disconnect plug.
Maximum size for the unit will be no greater than 5.9 inches (15 cm) wide by 3.8 inches (9.7 cm)
high by 3.5 inches (8.9 cm) deep.
The unit shall be capable of setting 10 different vehicle classifications with 1000 different vehicle ID
numbers per class. Setup will be through a SAE J1708 multi-purpose communications port and
provided Windows 2000, Professional or Windows NT 4.0 software.
The unit will monitor its transmitted data and check to see that the required identity pulses are
present. Feedback will be provided to the switch (see below) if the unit does not transmit data
pulses correctly.
A disable input shall be provided operating in either the latch or non-latch (normal) mode to turn
the unit off, when say a vehicle has arrived at its destination.
The emitter can be turned on with or without the strobe being activated (at the same time).
The unit shall come with a five (5) year manufacturer warranty. A Contractor installing any such
device will pass along the warranty to the end user.
An optional visible light filter (to block same) may be substituted for the front face of the unit.
3.
VEHICLE SWITCH UNIT
An on/off switch will be equipped with an indicator light providing internal diagnostics. The light will
be steady when operating, flash at 0.5 Hz rate when disabled and 2 Hz rate when inoperative.
The switch shall be able to initiate emergency, probe, transit or range setting features on the
emitter.
The switch shall be provided with a dashboard mounting bracket.
