The Model E-1000 series consists of detectors designed to meet or exceed NEMA Standards TS 2-1992 for Type
D detectors. These units are downward compatible to NEMA Standards TS 1-1989. In addition, the Model E-1000
series includes a version that is designed for use in Type 332 / 170 applications. The E-1000 detector is a four
channel, card rack type loop detector with individual channel detect and loop fail indications provided via four
high intensity red LEDs and an easy to read LCD screen. All detector settings and parameters are congured
using a set of four push-buttons and the LCD screen. The E-1000 offers advanced features providing built-in
diagnostic capabilities all of which are viewable by means of the LCD screen. These include 1.) real-time loop
frequency, 2.) loop inductance, and -∆L/L%, 3.) a bar-graph indication of relative inductance change (which
ensures proper selection of sensitivity level), 4.) a record of accumulated loop failures, and 5.) a timer countdown
of programmed timing functions.

E-1000 Series Specications
This is a basic performance specication and is not intended to be used as operating
instructions.
GENERAL CHARACTERISTICS:
Loop Frequency: The LCD screen displays the actual loop operating frequency for each
channel which makes it easy to quickly identify and eliminate crosstalk in the most difcult
to congure intersections. There are eight (8) selectable loop frequency settings per
channel (normally in the range of 20 to 100 kilohertz). The actual loop operating frequency
is a function of the loop / lead-in network and the components of the loop oscillator circuit.
Sensitivity: A unique bar graph displayed on the LCD makes it easy to quickly set
sensitivity at the ideal level for any loop / lead-in network situation. There are nine (9)
selectable sensitivity levels per channel, plus settings for Continuous-Call and Channel-Off.
See “SENSITIVITY, -∆L/L, & RESPONSE TIME” table.
Continuous-Call: When set to the Continuous-Call state, the channel output is
continuously in the Call state regardless of the presence or absence of vehicles over
the loop. The loop oscillator is disabled when in the Continuous-Call state. This state is
indicated by “CALL” ashing on the LCD. This option is selected from the Sensitivity
menu in Program Mode and is useful for checking controller response and other
troubleshooting activities.
Channel-Off: When set to the Channel-Off state, the channel output is continuously
in the No-Call state regardless of the presence or absence of vehicles over the loop.
The loop oscillator is disabled when in the Channel-Off state. This state is indicated
by “OFF” ashing on the LCD. This option is selected from the Sensitivity menu in
Program Mode and is useful for checking controller response and other troubleshooting
activities.
Call Delay: Each channel’s Call Delay is adjustable from 0 to 255 seconds in 1-second
steps. Call Delay time begins when a vehicle enters the loop detection zone. The remaining
Call Delay time is continuously displayed on the LCD. Whenever a Phase Green Input (call
delay override) signal (pin 1, 2, 3, or 10) is active (low state), the Call Delay function for that
channel is aborted and the Call Delay time is forced to zero.
Call Extension: Each channel’s Call Extension is adjustable from 0 to 25.5 seconds in 0.1second steps. Extension time begins when the last vehicle clears the loop detection zone.
The remaining Extension time is continuously displayed on the LCD. Any vehicle entering
the loop detection zone during the Extension time returns the channel to the Detect state,
and later, when the last vehicle clears the loop detection zone, the full Extension time
starts counting down again. NOTE: See Option 3, Call Extension Control for an alternate
mode of operation for Call Extension.
Presence / Pulse: One of two mutually exclusive modes of operation for each channel can
be selected in Program Mode:
Presence Mode: Provides a minimum Call hold time of at least 4 minutes (regardless
of vehicle size) and typically 1 to 3 hours for an automobile or truck.
Pulse Mode: 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 2 seconds. This enables
detection of subsequent vehicles entering the loop detection zone. After each vehicle
leaves the loop detection zone, the channel resumes full sensitivity within 0.5 seconds.
Max Presence Timer: Each channel’s Max Presence timer is adjustable from 1 to 999
seconds in 1-second steps, plus OFF. The Max Presence function is used to limit presence
time by automatically resetting a channel. If this function is enabled (on), the Max Presence
timer begins counting down when a Call is initiated and the remaining time is continuously
displayed on the LCD. If the loop becomes vacant before the Max Presence timer reaches
zero, the Call is dropped and no automatic reset occurs. If the End-Of-Green (EOG) function
is not enabled (off) and the Call is still present when the Max Presence timer reaches
zero, the channel is then automatically reset. If the EOG function is enabled (on) and the
Call is still present when the Max Presence timer reaches zero, the channel enters a Wait
state. The Wait state continues until the loop becomes vacant; or the Phase Green Input
signal for the channel (pin 1, 2, 3, or 10) transitions from green to not green with the Call
still present. If the loop becomes vacant rst, the Call is dropped and no automatic reset
occurs. If the Phase Green Input for the channel transitions from green to not green while
the channel is in a Wait state, the channel is automatically reset. The phase green signals
on pins 1, 2, 3, and 10 are also called Call Delay Overrides.
End-Of-Green (EOG): The EOG function is used to synchronize a channel reset with the
termination of the associated phase green. The EOG function is only available when the
Max Presence function is set between 1 and 999 seconds. It is not available when the Max
Presence function is OFF. When the EOG function is enabled (on), the channel will
automatically reset at the time the phase green input signal (pin 1, 2, 3, or 10) transitions
from the ON state to the OFF state if the Max Presence Time has counted down to zero
and is resting in the Wait state. The phase green signals on pins 1, 2, 3, and 10 are also
called Call Delay Overrides. If an out of range loop failure condition exists and is identied
(i.e. loop inductance is less than 20 microhenries or greater than 2500 microhenries) the
detector channel will not be reset at End-of Green and the channel will remain in the failed
state.
Option 1, Loop Inductance Display: When this option is enabled (on), the LCD
screen displays the total loop inductance (actual loop inductance plus actual lead-in
inductance) in microhenries for loop inductance values in the range of 20 to 2500
microhenries. NOTE: Enabling this option activates it for all channels. This option is
automatically disabled 15 minutes after activation or on loss of power.
Option 2, Loop Inductance -∆L/L Display: When this option is enabled (on), the
LCD screen displays the percentage of inductance change (-∆L/L value) during
the Call state. To facilitate viewing of the maximum change in the -∆L/L value
while trafc is in motion over the detection zone, the detector will hold the peak
-∆L/L value for a period of 2 seconds. NOTE: Enabling this option activates it for
all channels. This option is automatically disabled 15 minutes after activation or on
loss of power.
Option 3, Call Extension Control: When this option is enabled (on), the channel
will extend calls for the programmed extension time only when the Phase Green
Input signal (pin 1, 2, 3, or 10) is active for the channel. When this option is off,
the channel extends ALL calls for the programmed extension time. The signals on
pins 1, 2, 3, and 10 are also called Call Delay Overrides. NOTE: Each channel can
be enabled independently.
Option 4, Noise Filter Disable: When Option 4 is enabled (on), internal noise
ltering is disabled thus providing a faster response time. When this option is
off, internal noise ltering is utilized. When the detector is used in speed and/or
occupancy applications, the noise lter should be disabled (i.e. Option 4 on) to
provide the most accurate data possible. It is recommended that this option not
be activated. The factory default setting of “Off” provides stable operation in high
crosstalk environments. NOTE: Enabling this option activates it for all channels.
Changing the setting of this feature will reset the detector. See “SENSITIVITY,
-∆L/L, & RESPONSE TIME” table.
Option 5, Phase Green Loop Compensation: When Option 5 is enabled (on),
normal loop compensation is used until the Phase Green Input signal (pin 1, 2, 3,
or 10) becomes active. Once the Phase Green Input signal is active, concurrent
with a call output, the detector desensitizes the loop by 0.05% (-∆L/L) over a 15
second period. This desensitization “tunes out” small changes, such as adjacent
lane pickup, therefore minimizing the chance of max timing an empty lane. A small
motorcycle may also be tuned out following the start of Phase Green. This option
is useful in minimizing the effects of false detection from adjacent lane pickup
when a channel must be run with a high sensitivity setting to ensure detection of
motorcycles. When Option 5 is not enabled (off), normal loop compensation is
used. NOTE: Each channel can be enabled independently.
Option 9, Third Car Passage: Option 9 is a “paired channel” option. This means
that it takes two channels to implement this feature. Channel 1 is paired with
Channel 2 and Channel 3 is paired with Channel 4. When Option 9 is enabled (on),
the outputs of the paired channels (1 and 2 and/or 3 and 4) are logically ANDed
together. This means that while the loops for both of the paired channels are
occupied, a call will appear on both channels. While only one loop is occupied, or
neither loop is occupied, a call will not appear on either channel. The rst channel
with detection will enter a “pending” state while waiting for detection on the other
paired channel. While in the pending state, the LCD will show “Pnd” on the display.
The intent of this feature is for use in Protected / Permissive left turns. The expected
installation is a stop bar loop for the left turn lane connected to one channel, a queue
detection loop for the left turn lane connected to the other channel with a small
amount of delay time programmed, and the output of either channel connected to
the Vehicle Call input for the protected movement of the trafc controller. NOTE:
Refer to the Model E-1000 Series Operation Manual for complete installation and
operation details.
Option 10, Directional Logic: Option 10 is a “paired channel” option. This means
that it takes two channels to implement this feature. Channel 1 is paired with
Channel 2 and Channel 3 is paired with Channel 4. When Option 10 is enabled
(on), directional logic is enabled. Directional logic starts with a detection on one of
the paired channels. This channel will go into the “pending” state, display “Pnd”
on the LCD screen, and NOT output a call. When both of the paired channels have
detection, 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 rst channel. None of
the timing functions (Delay, Extension, Max Presence, or Detector Disconnect) of
the rst channel with a detection will time and the rst channel will always operate
in the Presence Mode regardless of programming for the channel. The second
channel with a detection will time all timing functions as programmed. The intent
of this feature is for use in parking lot applications where vehicles can enter or exit
from the same lane, 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. The expected installation is two loops, one after the other in the same
lane, spaced anywhere from slightly overlapping to 6 feet apart. NOTE: Refer to
the Model E-1000 Series Operation Manual for complete installation and operation
details.

E-1000 Series Specications
Option 11, Audible Detect Signal: When this option is enabled (on), an audible signal will
be activated whenever the detection zone for the selected channel is occupied. The audible
signal indicates actual occupancy of the loop detection zone. Timing and disconnect
functions have no affect on the audible signal. This feature allows a technician to watch
the detection zone on the street and conrm correct detector operation without having to
look at the detector display as well. Only one channel can have this feature active at a given
time. Turning this option on for one channel automatically turns it off for all other channels.
NOTE: This option is automatically disabled 15 minutes after activation or on loss of power.
Option 12.0, Detector Disconnect: The Detector Disconnect feature requires that the
Phase Green Inputs for each channel be connected to the proper controller phase. When
the Phase Green Input is not active (high), the detector shall operate normally. When the
Phase Green Input is active (low), at the end of each detection, the extension timer will
start to count down. If this timer reaches zero before the next detection, this channel will
no longer output a Call until the phase green input is not active. Because the extension
timer is used as a disconnect timer while in this mode, two different disconnect types are
available:
Option 12.1 OFF: Extension timing occurs and the extension timer also serves as the
disconnect timer during phase green. This will cause the Call output to remain in the
Call state until disconnect occurs. This may allow the user to use gap times appropriate
for the advanced loops without considering the effects on the stop bar loops.
Option 12.1 ON: Extension timing is disabled and the extension timer is used as the
disconnect timer. This will cause the Call output to follow the occupancy of the loop
detection zone until disconnect occurs.
The intent of this feature is for use in applications where a loop at the stop bar is not
needed after any waiting queue in the associated trafc lane is moving during the green.
Note: Refer to the Model E-1000 Series Operation Manual for complete installation and
operation details.

SPECIFICATIONS (ELECTRICAL):
Power: 10.8 to 30 VDC, 120 mA maximum, 2.1 Watts maximum.
Loop Inductance Range: 20 to 2500 microhenries with a Q factor of 5 or greater.
Loop Inputs: Transformer isolated. The minimum capacitance added by the detector is
0.068 microfarads.
Lightning Protection: The detector can tolerate, without damage, a 10 microfarad
capacitor charged to 2,000 volts being discharged directly into the loop input terminals,
or a 10 microfarad capacitor charged to 2,000 volts being discharged between either loop
terminal and earth ground.
Reset: Meets and/or exceeds NEMA TS 1 and TS 2 detector specications. Application of a
30-millisecond low state (0 to 8 VDC) to pin C resets all channels. The detector can also be
reset by removing and reapplying power or by changing the setting of Option 4 (Noise Filter
Disable). Each detector channel can be independently reset by pressing the CHAN button
until the desired channel is selected, then holding the CHAN button for 3 seconds. Also,
changing either the sensitivity or loop frequency of a channel will reset that channel. NOTE:
Resetting a channel or changing the setting of Option 4 does not disable any selectable
diagnostic functions. If any diagnostic option(s) (Option 1, Option 2, or Option 11) has
(have) been activated, it (they) will remain activated following the channel reset or change
of Option 4 setting. Resetting the detector by applying a 30-millisecond low state to pin C
or removing and reapplying power disables all selectable diagnostic features.
Phase Green Inputs: Also known as Call Delay Overrides. Meets and/or exceeds
all NEMA TS 1 and TS 2 requirements. Application of a low state voltage (0 to 8
VDC) to pin 1 (Ch. 1), pin 2 (Ch. 2), pin 3 (Ch. 3), and/or pin 10 (Ch. 4) causes the
delay timer for the channel to abort the delay timing function and also provides
control for Phase Green Loop Compensation, Max Presence Timing (End-of-Green),
Extension Timing, and Detector Disconnect, if the features are programmed.
Fail-Safe Outputs: Per NEMA TS 2, a conducting state indicates detection output.
Each detector channel output defaults to a Call state for any loop failure condition
or loss of power.
Channel Status Outputs: Per NEMA TS 2, each channel has an output to
communicate the status states of the channel as follows:
Normal operation . . . . . . . . . . . . . . . . . . . . . .Continuous Low or On State.
Detector failure . . . . . . . . . . . . . . . . . . . . . . .Continuous High or Off State.
Open loop . . . . . . . . . . . . . . . . . . . . . . . . . . . .50 ms On time, 50 ms Off time.
Shorted loop . . . . . . . . . . . . . . . . . . . . . . . . . .50 ms On time, 100 ms Off time.
Excessive inductance change (±25%) . . . . .50 ms On time, 150 ms Off time.
Solid State Output Ratings: Optically coupled eld effect transistors. 30 VDC
maximum drain to source. 50 mA maximum current. 1.2 VDC maximum transistor
saturation voltage. The output transistor is protected with a 33-volt zener diode
connected between the drain and source.
SPECIFICATIONS (OPERATIONAL):
Display: The LCD back-lighting illuminates whenever any push-button is pressed.
The back-lighting will extinguish 15 minutes after the last actuation of any pushbutton.
Detect Indicators: Each channel has a super-high-intensity, red, light-emittingdiode (LED) to indicate a Call output, Delay Timing, Extension Timing, Pending
state, or failed loop. Response Time: Meets or exceeds NEMA TS 1 and TS 2
response time specications. See “SENSITIVITY, -∆L/L, & RESPONSE TIME” table
for actual response times.
Self-Tuning: The detector automatically tunes and is operational within 2 seconds
after application of power or after being reset. Full sensitivity and hold time require
30 seconds of operation.
Environmental & Tracking: The detector is fully self-compensating for
environmental changes and loop drift over the full temperature range and the
entire loop inductance range.
Grounded Loop Operation: The loop isolation transformer allows operation with
poor quality loops (which may include one short to ground at a single point).
Loop (Fail) Monitor: If the total inductance of the channel’s loop input network
goes out of the range specied for the detector, or rapidly changes by more than
±25%, the channel will immediately enter the Fail-Safe mode and display “LOOP
FAIL” on the LCD screen. The type of loop failure will also be displayed as “L lo”
(for -25% change or shorted loop conditions) or “L hi” (for +25% change or open
loop conditions). This will continue as long as the loop fault exists. However, if the
detector is reset, or power is momentarily lost, the detector will retune if the loop
inductance is within the acceptable range. If any type of loop failure occurs in one
(or more) loop(s) in a group of two or more loops wired in parallel, the detector will
not respond with a fail-safe output following any type of reset. It is essential that
multiple loops wired to a common detector channel always be wired in series to
ensure fail-safe operation under all circumstances. The Fail-Safe mode generates a
continuous call in Presence Mode or in Pulse Mode. At the time of a loop failure,
the channel’s LED will begin repeating a burst of three ashes each one second.
The LED will continue these bursts until the channel is manually reset or power
is removed. If the loop “self heals”, the “LOOP FAIL” message on the LCD will
extinguish and the channel will resume operation in a normal manner; except the
LED will continue the bursts thus providing an alert that a Loop Fail condition
occurred. Each loop failure for the channel is counted and accumulated into the
Loop Fail Memory. The total number of loop failures written into the Loop Fail
Memory (since the last power interruption or manual reset) is viewed by stepping
through the channel’s functions in Program Mode to the “LOOP FAIL” message.
Full Restore To Factory Defaults: Pressing all four front panel switches
simultaneously and continuously for 5 seconds resets the detector and restores
all the factory default settings. The countdown of the 5-second period is displayed
on the LCD screen. Releasing any of the switches before the countdown ends
will abort the Full Restore operation. See “FACTORY DEFAULT SETTINGS” table.
Display Test: Pressing any two of the front panel switches simultaneously will
display all possible symbols and messages on the LCD screen.
Note: Entries in this table are based on the assumption that both detector channels are
set to the same sensitivity. To achieve the exact response times listed above, the Sensitivity level of both channels must be set the same. To approximate response times for a
detector with channels set to different sensitivities, look up the response time for each
channel and divide it by four, then add these times together.
