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.
