Section 1 General Description

This product manual was written for people installing, operating, and maintaining the Reno A & E Model E-1000 Series inductive loop vehicle detector. The Model E-1000 is a four channel, rack mount type, inductive loop vehicle detector designed to meet or exceed NEMA Standards TS 2-1992 and is downward compatible to N EMA Standards TS 1-1989.

The Model E-1000 uses a microcontroller to monitor and process signals from the loop / lead-in circuits, Phase Green Inputs, and the reset input. It uses these inputs to deter mine how to control the four detector channel outputs and the four TS 2-1992 stat us outputs (if equipped). A Liquid Crystal Display ( LCD), four light emitting diodes (LEDs), and four front panel pushbuttons are used to display and program all detector functions. Several diagnostic modes are available to aid technicians and service personnel in troub leshoot ing detect io n problems.

The use of an LCD is what distinguishes this detector from that of other manufacturers. It allows more information, never before available, to be displayed to the user during nor mal operation of the detector. The LCD makes it easy to view and adjust all programmable detector options and settings. It is no longer necessary to check or change detector sett ings with DIP switches. An eight-se gment bar graph at t he top of the LCD ca n be used to provide a graphical representation of the relative change of inductance as seen by the detector at the current sensitivity level. The bar graph automatically takes into account loop size, loop inductance, number of loops, number of turns, loop geometry, lead-in length, etc. The bar graph functions as a sliding scale that relates to the programmed Sensitivity Level. The first (left-most ) bar graph segment represents the mini mum inductance change necessary for the detector to output a call at the currently selected sensitivity level. Larger inductance changes will indicate more se gments. Each additional segment indicates that the next sensitivity level has also been met or exceeded. When used in this manner, t he bar graph provides an indication of w hethe r the s ens itivit y is set too high or too low, facilitating the ideal setting of the sensit ivity level.

All programmed settings are stored in non-volatile memory and can only be changed by programming new settings. Loss of power or a de tector reset will not change any of t he programmed settings. If a loop failure occurs, the LCD will display the type of loop failure as L lo (for -25% change or shorted loop conditions) or L hi (for +25% change or open loop c onditions). Each loop failure is counte d and accumulated in the Loop Failure Memory. The number of failures since the last detector reset or power interrupt ion is very us eful infor mation during analysis of intermittent loop operation.

The Model E-1000 Series detector is a scanning detector. The scanning operation sequentially activates the ON and OFF cycle of each channel’s oscillator. Since only one channel’s loop(s) is (are) active at a given time, crosstalk between adjacent loops connected to t he same scanning detector is minimized. The Model E-1000 Series’ unique scanning process also disconnects the capacitors and dampens the oscillator during the o ff cycle. This eliminates oscillation past the OFF point (ringing or deca y) every time the loop circuit is scanned which can result in crosstalk. When operating in the Program Mode, the Model E-1000 Series d isplays the real time loop freque ncy rea ding for each channel. The eight frequency settings ca n be incremented or decremented to p rovide precise frequency readings, removing any guesswork when cha nging frequency settings to eliminate crossta lk. NOTE: Adjacent loops connected to different c hannels of a non-scanning detector or different scanning detectors should be set to different frequencies with maximum separation.

The Reno A & E Model E-1000 Series utilizes the first major innovation in inductive loop detectors since the introduction of digital detectors. The programming of all of the detector’s parameters with four normally open pushbutton switches not o nly simplifies setup by removing binary coded DIP s witches, but also increases the reliability of the detector by eliminating the dependence on switch contacts during normal operation. The detailed descriptions displayed on the LCD eliminate the interpretation of numerous LED flash rates to determine the detector status. In addition, the Model E-1000 offers t he versatility of software c ontrol. Special functions are possible with a simple change of the socket-mounted microprocessor. Special functions are de fined as unique options (e.g. Option 5, Opt ion 12, etc.). Spe cial option functio ns are activated thro ugh the use o f the LCD menu option programming.

The Model E-1000 Series is comprised of the following detectors:

E-1100-SS For 332 cabinet (170 controller) applications ca lling for a four channel, 2” wide (double width),

E-1200-SS For NEMA TS 1 -1989 and TS 2-1992 applications calling for a four channel, four c hannel, 2”

Section 2 General Characteristics

2.1 LOOP FREQUENCY

There are eight (8) selectable loop frequency settings (nor mally in the range o f 20 to 100 kilohertz) pe r channel.

The actual loop operating frequency is a function of the loop / lead-in network and the components of the loop oscillator circuit. The d igital display of the actual loop operating frequency for each setting makes it easy to quickly identify and eliminate crossta lk in the most difficult to configure intersections. The frequency display is typica lly very stab le when the loop is vacant and veh icles are not passing nearby the loops. If the reading is varyin g by more than ±1 in the last digit, this is an indication of possible crossta lk betwee n loops.

2.2 SENSITIVITY

There are eight (8) selectable loop frequency settings (normally in the range of 20 to 100 kilohertz) per channel. The actual loop operating frequency is a function of the loop / lead-in network and the components of the loop oscillator circuit. The digital display of t he actual loop operating frequency for each setting makes it easy to quickly identify and eliminate crossta lk in the most difficult to configure intersections. The frequency display is typica lly very st able when t he loop is va cant and ve hicles ar e not passi ng nearby the loops. I f the readin g is varyin g by more than ±1 in the last digit, this is an indication of possible crosstalk between loops.

2.3 PRESENCE / PULSE

One of two mutually exclusive modes of operation for each channel is available. Presence or Pulse mode is toggled by momentarily pressing e ither the  (UP) or  (DOWN) butto n.

PRESENCE MODE: Provides a call hold time of at least four minutes (regardless of vehicle size) and typically one to three hours for an automobile or truck.

PULSE MODE: An output Pulse of 125 ±10 milliseconds duration is generated for eac h ve hicle ente ring t he loo p detection zone. Each detected vehicle is instantly tuned out if it remains in the loop detection zone longer than two 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.

2.4 CALL DELAY

Each channel’s Call Delay is ad justab le from 0 t o 255 seconds in one-second steps. Call Delay time starts counting down w he n a veh ic le e nt ers t he loo p detect ion zone. The re maining Call Dela y time is c ontinuously displa yed 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 fo r that channel is aborted and the C all Delay time forced to zero.

2.5 CALL EXTENTION

Each channel’s Call Extension is adjustable from 0 to 25.5 sec onds in 0.1-second steps. Extension time starts counting down when the last vehicle clears the loop detection zone. The remaining Call Extension time is contin uous ly d isp la yed o n the LCD. Any veh icle ente r ing t he lo op de tec tio n zo ne d uri ng the Ca ll Ext ens io n ti me period causes the channel to return to the Detect state, and later, when the last vehicle clears the loop detection zone, the full Call Exte nsion time starts counting down again. (See Option 3, Call E xtension Control, for an alternate mode of operation for Call Extension.)

2.6 MAX PRESENCE TIMER

When activated, each channel’s Max Presence timer is adjustable from 1 to 999 seconds in one-second steps. A setting of OFF turns the Max Presence timer off. The Max Presence function is used to limit presence time, by automatically resetting the channel. If this function is enabled (ON), the Max Pre sence timer begins counting down when a call is initiated and t he remaining ti me is continuously displaye d on the LCD. I f the loop becomes vacant before the Max Presence timer reaches zero, the call is dropped and no automatic reset occurs. If the EndOf-Green (EOG) function is not enabled (OFF) and the call is still present when the Max Presence timer reaches zero, the cha nnel then is aut omatically reset. If the EOG functi on is e nabled (ON) and the call is still present w hen the Max Presence timer reaches zero, the channel enters a Wait state. The Wait state continues until either the loop becomes vacant or the Phase Gree n Input signal for a channel (p in 1, 2, 3, or 10) transitions fro m green to not green with the call still present. If the loop becomes vacant first, the call is dropped and no automatic reset occurs. If the P hase Gree n Input tr ansitio ns from gre en to not green whil e a channe l is in a W ait state , the chan nel is automatically reset. The signals on pins 1, 2, 3, and 10 are also called Call Delay Overrides. (See Section 3.2, Phase Green Input specifica t ion for volt age leve ls . )

2.7 END-OF-GREEN (EOG)

Each channel’s EOG setting can be toggled O N or OFF b y moment arily pr essing either the  (UP) or  (DOWN) button. The EOG function is used to synchronize resetting of a detector with the termination of the associated phase green. The assumption is that t his is the sa fest point in t ime to reset the c hannel. T his assumption is based on the premise that at the termination of the associated phase green, traffic should be moving, and therefore, a reset would not result in the loss of a call when traffic comes to rest over the loop(s). The EOG func tion is only

889-0503-1 Model E-1000 Operations Manual Rev Apr 2020 Page 2 of 25

Page 9

available when the Max Presence function is set between 1 and 999 seconds. It is not available when the Max Prese nce fun ct io n is O FF. W he n t he E OG function is enabled (ON), the channel will automatically be reset at the same 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 . T he s igna ls on p ins 1 a nd ar e a lso called Call Delay Overrides. (See Section 3.2, Phase Green Input specifications for voltage levels.)

2.8 OPTION 1: LOOP INDUCTANCE DISPL AY

Each cha n ne l’s Loo p I nd uct a nce Dis p la y se tt in g ca n be t o ggle d O N or O FF b y mo me nta r il y pre ss i ng e it her the  (UP) or  (DO W N ) b u t to n. W hen this o p ti o n is e nabled (ON ) , t he LC D d is p la ys the tota l lo o p inductanc e (a c t ua l loop inductance plus actual lead-in in ducta nce) in m icrohe nries for loop induct ance va lues i n the ran ge of 20 to 2500 microhenries. By recording the inductance of the loop / lead-in circuit when it is first insta lled, the actual inductance can be compared to the expected inductance to help identify defective loop / lead-in circuits. Loop / lead-in inductance can be easily estimated using the simple formulas included in Section 8.7 of this manual. NOTE: Enabling this option act ivates it for all c hannels. This option is a utomatically disabled 15 minutes after activation or on loss of power.

2.9 OPTION 2: LOOP INDUCTANCE -∆L/L DISPLAY

Each cha n ne l’s Loo p I nd uct a nce -∆L/L Display sett ing can be toggled ON or OFF by momentarily press ing either the  (UP) or  (DOWN) but ton. When th is option is e nabled (ON), the LCD displays the percentage of induct ance change (-∆L/L value) during the Call state. To fac ilitate the viewing of the maximum amount of change in the -∆L/ L value w hile tra ffic is i n motion o ver the de tectio n zone, t he channe l holds t he peak -∆L/L value for a period of two seconds. NOT E: Enabling this option activates it for all channels. This option is automatically disabled 15 minutes after activation or on loss of power.

2.10 OPTION 3: CALL EXTENTION CONTROL

Each cha nnel’ s Cal l Exte nsion C ontro l set ting ca n be to ggled O N or OF F by mo mentar ily pre ssin g eithe r the  (UP) or  (DO WN ) b ut to n. W he n t h is o pt io n is e nab led (O N) , t he c ha n nel w ill e x tend ca l ls f or t he pr o gra mme d extension t i me only when the Phase Gree n Input s ignal (p in 1, 2, 3, or 10) is active. When this option is OFF, the channel extends ALL calls for the programmed exte nsion time. The signals o n pins 1, 2, 3, and 10 are also ca lled Call Delay Overrides. (See Section 3.2, Phase Green Input specifications for voltage levels.)

2.11 OPTION 4: NOISE FILTER DISABLE

The detector’s Noise Filter Disable setting can be toggled ON or OFF by momentarily pressing either the  (UP) or  ( DO WN ) b utt o n. W he n Op t io n 4 is e nab le d ( ON ), inte r na l no is e f ilt er in g is d isa ble d t hus p ro vid in g a fas te r response time. When this opt ion is OFF, internal noise filtering is utilized. When the detector is used in speed and/or occupancy applications, the noise filter s hould 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 o f 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 all detector channels.

The Loop Fail Count is not reset when the setting of Option 4 is changed. Also, changing the setting of Option 4 will not cause the prior Loop Fail indication to cease (see Section 5.3, Loop Fail Indications).

2.12 OPTION 5: PHASE GREEN LOOP COMPENSATION

Each channel’s Phase Green Loop Co mpensation setting can be toggled ON or OFF by mo mentarily pressing either the  (UP) o r  (DOWN) button. When Option 5 is enabled (ON), normal loop compensation is used until the Phas e G re e n I n p ut signal (p i n 1 o r 2) becomes active. Once the Phase Green Input signal is active, the channel desensitizes the loop. Maximum desensitization is 0.05% (-∆L/L). This desensitization tunes out small changes, such as adjacent lane pickup, therefore minimizing the chance of max timing an empt y lane. Note: A small motorcycle may also be tuned out in a short period o f time following the start of Phase Green. This optio n is useful in minimizing false detection resulting from adjacent lane pickup when a channel must be run with a high sensitivity s etting. When Opt ion 5 is not enabled (OFF) , norma l loop compensation is used.

2.13 OPTION 9: THIRD CAR PASSAGE

Each channel’s Third Car Passage setting can be toggled ON or OFF by momentarily pressing either the  (UP) or  (DO WN ) b ut to n. Op tion 9 is a paired channe l option. This means that it takes two c hannels to imple ment the

feature. Therefore, when this option is toggled ON or OFF in one channel, its paired channe l is a lso set to the sa me state. In the Model E-1000, C hannel 1 is paired with C hannel 2 and Channe l 3 is paired with C hannel 4. NO TE: Option 9 is mutually exclusive with Opt ion 10. Turning ON one option will automatically tur n OFF the other option.

When Op t ion 9 is e nab led (ON ) , t he o ut pu t o f the tw o p air ed c ha n ne ls a re logically ANDed together. This means that while the loops for both of the paired channels are occ upied, a call will be output on both channe ls. While only one channel is occupied, or neither channel is occupied, a call will not be output for either cha nne l. The f irs t

Loop A

channel with detection will enter a pend ing state w hile wait ing for detect ion on the ot her pa ired cha nnel. While in the pending state, the LCD will show Pnd on the d isplay. This feature is intended to be used in Protected / Permissive left turn situations. The expected ins ta llation is a stop bar loop for the left turn lane connected to one c hanne l, a queue detect ion loop (with a s mall amount o f delay ti me programmed) for the left turn lane connected to the other channel, and the output of either channel connected to the Vehicle Call input for the protected movement of the traffic controller.

Basic Installation - Loop A is the Queue Detection loop and Loop B is the Stop Bar loop.

Car enters Loop A - No call is output.

Car proceeds to Loop B - No call is output.

Additional cars enter the left turn lane - When the back of the queue reaches Loop A while a car is still over Loop B, a call will be output.

When Third Car Passage is turned on, as the first vehicle enters the left turn lane it will dr ive over t he queue detection loop. Since there is no vehic le over the stop bar loop, there is no call output genera ted. The vehicle advanc es to t he sto p bar loop. Still, no out put is gene rated beca use the re is no veh icle o ver the queue detection loop. If the vehicle traffic in the left turn lane backs up to the queue detection loop, then the stop bar loop and the queue detection loop will both be occupied at the same time. This will cause the detector to generate a call to the traffic co ntroller to service the protected movement for the left turn. This should help clear the queue of vehicles in the left turn lane. The spacing between the stop bar loop and the queue detection loop controls the size of the queue needed to generate a call to the protected movement of the controller. The delay time on the Queue Detection loop should be sufficiently long that vehic les driving over this loop to enter the queue do not generate a call.

2.14 OPTION 10: DIRECTIONAL LOGIC

Each c ha n nel’s D ire c t ional Lo gic setting can be toggled ON or OFF b y momentarily press ing either the  (UP) or  (DOWN) button. Option 10 is a paired c hannel option. This means that it takes two channe ls to implement t he

feature. Therefore, when this option is toggled ON or OFF in one channel, its paired channe l is a lso set to the sa me state. In the Model E-1000, C hannel 1 is paired with C hannel 2 and Channe l 3 is paired with C hannel 4. NO TE: Option 10 is mutually exclusive with Opt ion 9. Turning ON one option will automatically tur n OFF the other option.

When Op tion 10 is enab led (ON ), dire ctiona l logic is enabled. Directional logic starts with a detection on one channel. This channel will go into the pending state, display Pnd on the LC D , a nd N O T output a c a l l. W hen both of the paired channe ls have detect ion, the last channel to have d etect ion will output a call until the detection for the last c ha n ne l e nd s , e ve n if t h e d e te c t ion ends fo r t he fi rs t c hannel. None of t he t i mi n g f un c t io ns of the f ir s t channe l with a detection will ti me (Delay, Extens ion, Max Presence, a nd Detector Disconnect) a nd the first channel w ill always operate in the Presence Mode regardless of the programming of the channel.

This feature is intended to be used in parking lot applications where vehicles can enter or exit from the same lane, freeway ramps for wrong way detection, and left tur n la ne s w he re o t her movements in t he inte rs ec ti o n te nd t o cl ip the detection zone of the left turn lane. The expected installation is two loops, one after the other in the same lane, spaced anywhere from slightly overlapping to 6 feet apart. NOTE: Contact a Field Engineer at Reno A & E

regarding proper loop configurations and spacing for specific applic ati ons.

Loop B

Loop A

When Directional Detectio n is turned on, a vehicle entering the first loop will cause that channel to enter t he pending state. As the vehicle enters the second loop w hile still occupying the first loop, the second channel will enter the Call state while the firs t channe l remains in t he pending s tate. A call is never outp ut on the first c hannel with a detection. Under normal conditions both outputs can never be on at the same time. However, if one of the loops fail, both outputs will come on and stay on until the failure is correc te d.

2.15 OPTION 11: AUDIBLE DETECT SIGNAL

Each c hanne l’s, A udible Detec t Sig nal set ting c an be t oggled ON or OFF b y mome ntar ily pre ssing e ither the  (UP) or  (DOWN) butto n. Only one channel can be turned ON at a time. Turning this option ON for one channel auto matically turns it OFF for the other channels. W hen this o ption is enable d (ON), a n 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 effect on the audible signal. This feature allows a technician to watch the detection zone on the street and confirm correct detector operation without having to look at the detector display as well. NOT E: This option is automatically disabled 15 minutes after activation or on loss of power.

2.16 OPTION 12: DETECTOR DISCONNECT

Each channel’s Detector Disconnect se tting can be toggled ON o r OFF and the Extension t imer toggled between ON and OFF by momenta r il y pr es sing ei t h er t he  (UP) or  (DOWN) button. The Detector Disconnect feature require s tha t the Phase Gree n Inp ut for t he channel be connected to the proper controller phase. When the Phase Green I nput is no t a c t i ve , t he c hannel s hall ope ra te no r mally. W hen the P ha s e Gr e e n I np ut is a c t iv e , t he e xt e nsion timer will start to count down at the end of each detection. 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. Since the extension timer is used as a disconnect timer while in this mode, two different disconnect types are available:

Optio n 12.1 OF F : Extension timi ng still occurs and the extension timer is also t he disconnect timer during phase green. This will cause the call output to re main in the Call state until disconnect oc curs. This may allow the user to use gap times appropriate for the advance loops without considering the effects on the stop bar loops.

Option 12.1 ON: E xte ns ion timing is disabled and the extension timer is used as the disconnect timer. T his will cause the call output to follow the occupation of the loop detection zone until disconnect occurs.

This feature is intended to be used in applications where a loop at the stop ba r is not needed after any waiting queue in the associated traffic lane is moving during the green phase. The expected installation is a stop bar loop

(typically a 20΄ to 30΄ long detection zone) and an advance detection loop (typically a 6΄ long detection zone) for a

single traffic lane. This feature provides a means for keeping the stop bar loop from placing ca lls to the traffic controller after the stop bar loop has served its intended purpose during the beginning period of the associated green phase. The channel connected to the stop bar loop would have the Detector Disconnect feature turned ON and have a programmed extens ion time tha t functions as the disconnect time. The channel connected to the advance detection loop would be programmed as normal.

This example assumes an extension time of 2 seconds. The dott ed lines show where di sconnect would occur. Phase

Green is the state of the light (actual Phase Green Input is inv er ted).

When the Detector Disconnect feature is turned ON and the signal is not green, the channel outputs calls to the traffic controller as usual. W hen the signa l turns gree n, vehicles begin to move and eventually the stop ba r detection zone is cleared. At the time that the stop bar detection zone is cleared the disconnect timer begins to count down. If another vehicle enters the stop bar detection zone before the disconnect timer reaches zero, the channe l o utp u ts the ne w c al l t o the traffic controller and the disconnect timer is reset to its initial value. Once the stop bar detection zone remains clear for a time equal to the programmed disconnect time, the detector channel is disable d a nd w il l no t ge nera te a ny fu rt her c alls t o t he traffic controller until after the green has terminated. When the stop bar detection loop is disabled, the green phase can only be extended by vehicles detected by the advance detection loop. NOTE: The disco nnect t imer will alwa ys time a n initial gap each t ime tha t the p has e t ur ns gre e n. If Option 12.1 is OFF, the channel will generate an output for the specified extension time at the start of each green phase.

(17.46 cm) long including connector (not including front handle). Model E/2 (single width faceplate) - 4.50 inches (11.43 cm) high x 1.20 inches (2.84 cm) wide x 6.88 inches (17.46 cm) long including connector (not including front handle). Handle adds 1.00 inch (2.54 cm) to depth measurement.

PERATING TEMPERATURE: -40° F to +180° F (-40° C to +82° C).

IRCUIT BOARD: Printed circuit boards are 0.062 inch thick FR4 material with 2 oz. copper on both sides and

plated through holes. Circuit board and components are conformal coated with polyur ethane.

ONNECTOR: 2 x 22 pin 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.

3.2 MINIMUM FLASH DIP SWITCH PROGRAMMING

OWER: 10.8 to 30 VDC, 120 mA maximum, 1.8 Watts maximum.

OOP INDUCTANCE RANGE: 20 to 2500 micro henries w ith a Q factor of 5 or greater.

OOP INPUTS: Transformer isolated. The minimu m capacita nce added is 0.068 microfarad.

IGHTNING PROTECTION: Meets and/or exceeds all applicable NEMA TS 1-1989 specifications for transient

voltage protection. Each channel 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 bein g discharged between either loop terminal and earth ground.

ESET: Meets and/or exceeds NEMA TS 1-1989 and TS 2-1992 detector specifications. Applicat ion of a 30-

millisecond low state (0 to 8 VDC) t o pin C resets all cha nnels. The detector can a lso be reset by removing and reapplying power or by changing t he setting of Option 4 (Noise Filter Disable). E ach detector channel can be independently reset by pressing the CHAN button until the desired c hannel is selected, then pressing and ho lding the CHA N b ut t o n fo r t hr e e se c o nd s . A ls o, c ha n gi n g either the sensitivit y or loop fr e q uency o f a channe l will res e t that channel.

HASE GREEN INPUTS: Also known as Call Delay Overrides. Meets and/or exceeds all NEMA TS 1-1989 and TS

2-1992 requirements. Application of a low state voltage (0 to 8 VDC) to pin 1 (Ch. 1) and/or pin 2 (Ch. 2) and/or pin 3 (Ch. 3) and/or pin 10 (C h. 4) causes the delay timer for the channel to abort t he delay timing function a nd also provides control for Phase Green Loop Compensation, Max Presence Timing (End-of-Green), Extensio n timing, and Detector Disconnect, if the features are programmed.

AIL-SAFE OUTPUTS: Per NEM A TS 2-1992 - co nducting state indicates detection output. Each detector channel

output defaults to a CALL state for any loop failure condition or loss of power.

HANNEL STATUS OUTPUTS: Per NEM A TS 2-1992 - each channel has an output to communicate the status states

of the c hannel as follow s:

SOLID STATE OUTPUT RATING: Optically isolated. 30 VDC maximum collector (drain) to emitte r (source). 100 mA ma ximum s atu rat ion c urre nt. 2 VDC maxi mum t rans isto r satur atio n vol tage. The o utput is pr otect ed w ith a 33-volt Zener diode connected between the collector (drain) and emitter (source).

four, then add these times together.

ETECT INDICATOR: Each channel has a super bright, high intensity, red light e mitting diode (LE D) to indicate a

Call Output, Delay Timing, Extension Timing, Pending State, or Failed Loop co nditio n.

ESPONSE TIME: Meets or exceeds NEMA TS 1-1989 and TS 2-1992 response time specifications. (See Section

3.4 for actual response times.)

ELF-TUNING: The detector automatically tunes and is operational within two seconds after application of power

or after being reset. Full sensitivity and hold time require 30 seconds of operation.

NVIRONMENTAL & TRACKING: The detector is fully self-compensating for environmental changes a nd loop drift

over t he full te mperature range and the entire loop inductance r ange.

ROUNDED LOOP OPERATION: The loop is olation transformer allows operation with poor qualit y loops (which may

include one short to ground at a single point).

OOP FEEDER LENGTH: Up to 5000 feet (1500 m) maximum with proper feeder cable and appropriate loops.

LOOP (FAIL) MONITOR: If the tot a l in duc ta nc e o f t he c ha n ne l’s loo p inp ut ne tw or k go e s o ut o f t he ra nge sp ec i fied for the detector, or rapidly changes by more than ±25 %, the channel will immediate ly e nte r t he Fail-Safe mode and display LOOP FAIL o n the LCD. The type of loop failure will also be disp layed 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. At the time of a loop failure, the

channel’s LED will begin to flash at a rate of three flashes per second. The LED will continue this display pattern until the channel is manually reset or power is removed. If the loop self-he als, the LOO P FAIL message on t he LCD will extinguish and the channel will re sume operation in a normal manner; exce pt the LED will continue t he three flashes per second display pattern, thus pro viding an alert that a prior Loop Fail condition has occurred. Each loop failure for the channel is counted and accumulated into the Loop Fail Memory. The total nu mber 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 until the LO O P FAIL messa ge is dis played .

Section 5 Installation and Set-Up

The detector has no DIP sw itches or jumpe rs to configure. P lug the detecto r into an appropriate ly wired rack and apply power. If the detector is not new from the factory, it may be advantageous to reset the detector back to the factory defaults to avoid having to check every setting for eac h channel. To reset the detector to factory default, press and ho ld a ll fou r p us hb utt on s w itc hes s imul ta ne o us ly fo r five se co nds . Whe n al l fo ur buttons are depressed, the display will start counting down from five (5). When the countdown reaches zero (0), releasing the pushbuttons will reload the factor y de fau lts and reset all channels.

All operating parameters can be adjusted from the front panel. The detector continues to operate normally while it is in t he Program Mode . The value cur r ently displayed is alw ays the actua l value being use d. Exa mple: If you are changi ng the de la y t ime, t he t ime d isp la ye d a t the ins ta nt tha t a ve hic le e nter e d the detection zone for that channel would be the value used for the delay timer.

Pressing the FUNC button enters t he Progra m Mode. The FUNC button has a n auto repeat function. This a llows quick navigation to the desired parameter. T he FUNC button only moves forward through all of the parameters. There is no way to move backwards through the parameters.

While viewing any parameter, pressing t he CHAN button will display the same para meter for the next channel. The currently selected channel is indicated at the bottom of the LCD. Pressing and hold ing the CHAN button for one second will exit the Program Mode and return to the Normal Mode.

5.3 LOOP FAIL INDICATIONS

If the to tal induc tanc e of a c han nel’s loop inp ut net work goes out o f the range specified for the detector, or rapidly c hanges by more than ±25%, the channel will enter the Fail-Safe mode and LOOP FAIL will be displayed on the LCD. The type of loop failure wi ll a ls o be d isp la ye d a s L lo (for -25% change or shorted loop cond itions) or L hi (for +25% change or open loop conditions). This will cont inue as long as the loop fault exists. Fail-Safe mode generates a continuous call in Presence Mode and in Pulse Mode. At the ti me of a loop failure, the channel’s LED will begin to flash at a rate of three flashes per second. The LED will continue this disp lay pattern until the channel is manually reset or power is removed.

If the loop self-heals, the LOOP FAIL message on the LCD will

exting uish and t he channel w ill resume operatio n in a norma l manner; except, the LED will continue the three flashes per second display pattern, thus, providing an alert that a prior Loop Fail condition has

occurred. Each loop failure is counted and accumulated into the Loop Fail Memory. The total number of loop failures for the channel is written into the Loop Fail Memory (since the last power interruption or manua l reset) and can be seen by stepp ing through the channel’s functions in Pro gram Mode to the LOOP FAIL display.

This is a useful tool to identify intermittent loop prob lems. If the count is extremely high for the pe riod of time observed, the problem is very likely a loose connection (check for loose connections at the terminal strip and bad splices in the field). The Loop Fail Count is reset when power is removed from the detector. This prevents the Loop Failure Count from moving to another loop, if the detector is moved to a new location.

To view the Loop Fail Count, repe atedly p ress the FUNC button unt il the LOOP FAIL display is shown. The Loop Fail Co un t d is p lay is aft er the OP TI ON d is pla ys . P res s in g th e  (UP) or  (DOWN) button while the Loop Fail Count is displayed will reset the count to zero.

NOTE: The Loop Fail Count is not reset when the setting of Option 4 (Noise Filter Disable) is changed or when the channel’s sensitivity or frequency is ch anged. The prior Loop Fail indic ation will continue u ntil the Lo op Fail Count is reset to zero.

5.4 SETTING SENSITIVITY USING THE BAR GRAPH

The bar graph is a graphical representation of the relative change of inductance as seen by the channel. It automatically takes into account the channel’s sensitivity setting, loop geometry, configuration, lead-in lengt h, etc. The first bar segment represents the minimum inductance change (set by the sensitivity level) necessary for the channe l to o utput a cal l. Eac h addi tiona l se gment t o the r ight repre sents the induct ance c hange in exc ess o f the next se nsitivit y thresho l d . Us ually, t he larger the vehicle, the greater the -∆L/L; thus, more and more segments are displayed. The bar graph can be used as a precise indicator to select the proper sensitivity level.

The bar graph below shows the deflection (3 s eg me nt s) o f a ve hic le w it h Se ns it iv it y s et to le ve l 4. T he ve hic le in the loop zone is causing a change of inductance greater than 0.32% -∆L/L or Sensitivit y Level 2.

5.5 SETTING SENSITIVITY FOR MOTORCYCLE DETECTION USING THE BAR GRAPH

The bar graph can also be used to select the proper sensitivity level for small motorcycle detection. The relative change of inductance caused by a motorcycle and a single automobile are proportional on any loop configura tion. Select ing the sensitivity le vel that causes the bar graph to display the seventh segment for a single standard automobile automatically sets the sensitivity to detect small motorcyc les. Follow the steps below:

displayed on the bar graph. (4)

Note: This method applies to conventional loop configurations only. Other loop configurations, such as QuadrupoleTM, will require a different method to correctly set sensitivity for motorcycle detection. Increasing the sensitivity to detect motorcycles in some loop configurations will make the loop sensitive to adjacent lane detection. If adjacent lane traffic is detected, the phase will max time whe n no vehicles are present in the loop (see Option 5 - Phase Green Loop Compensation for a possible solution).

Section 7 Theory of Operation

The Re no A & E M o d e l E -100 0 dete cto r digita lly measures changes in the resonant frequency of four independent loop circuits to determine if a vehicle has entered the detection zone. The Model E-1000 Series detector applies an excitation voltage to each loop c ircuit resulting in the loops oscillat ing at their resona nt freq uency. The cur rent flow in the loop wire creates magnetic fields around the loop wire. When a vehicle passes over the loop area, the conductive metal of the vehicle causes a loading of the loop’s magnetic fields. The loading decreases the loop inductance, which causes the resonant frequency to increase. By continuously sampling the loop’s resonant frequency, the magnitude and rate of change can be determined. If the frequency change exceeds a selectable thres hold (se t b y the s ens it ivity settings), t he channel w ill activate an outp ut signal. If the rate of change is s low, typical of environmental drift, the channel will continuo usly track and compensate for the change. The Mode l E1000 detector also monitors the loop frequency for out of range c onditions such as an open or shorted loop circuit.

The Model E-1000 detector is a scanning detector. The scanning method sequentially turns each channel’s loop oscillators on and off. Each channel’s os cillator circuit supplies the e xcitation voltage that is coupled to the loop circu it by a loo p isolatio n transfo rmer. The channel’ s oscilla tor circu it supplie s the exci tation vo ltage that is coupled to the loop circuit by a loop isolation transformer. The tra nsformer pro vides high co mmon mode is o lat i on between the loop and detector electronics , which allows the channel to o perate on poor quality loops including a single short to ground. The transformer also limits the a mount of static energy (lightning) that ca n transfer to the detector electronics. A spark gap transient suppression device is co nnected across t he loop inputs connected to t he isolation transformer. This device dissipates static charges before they reach the transformer. A network of four capacitors is connected to the detector side of the isolation transformer. Three of the capacitors can be switched in or out of the oscillator circuit to shift the frequency of the loop oscillator circuit thus providing frequency separation between adjacent loops. The three switchable capacitors are electronically switched using FETs and are select ed when p rogram ming parameter values with the front panel pushbutto n switches.

The outputs from the four loop oscillators are tied together and fed into a co mmon squaring circuit. This is possible since the detector is a scanning detector that allows only a single loop oscillator to be operat ing at any given time. The sine wave from the loop oscillator circuit is squared to provide a precise zero crossing s ignal for the input to the microcontroller. T his s ig nal is c al led the loo p sa mp le. The loo p sa mp le is a n in te gra l nu mbe r o f complete oscillations from the loop oscillator circuit. The number of loop oscillations counted is a function of the selected sensitivity setting for the channel. The required number of loop oscillations needed for a loop sample increases as the sensitivity setting is increased. The microcontroller uses the period of the loop sample for accumulating high-speed (32 MHz) crysta l clock pulses generated by the microcontroller’s interna l high-speed crystal oscillator. The number of crystal clock pulses accumulated during consecutive loop samples is compared to the internal reference number of crystal clock pulses stored in the microcontroller’s memory.

When a vehicle enters the loop zone the loop inductance decreases. This decrease in loop inductance causes an increase in the loop oscillator frequency. In turn, an increase in loop oscillator frequency results in a decrease of the time period for the loop sample. Hence, when a vehicle enters the loop zone the number of crystal clock pulses accumulated during a loop sample period decreases. By comparing the new count with the reference count, a percentage change can be calculated that indirectly relates to the inductance change. I f the magnit ude of the change exceeds a selectable threshold (sensitivity setting), the channel activates an output device. The rate of change is also monitored. Slow rates of change caused by environmental fluctuations are tracked and automatically compensated for. The microcontroller uses the high-speed crystal clock count to calculate the loop inductance, frequency and percentage of change. If selected, the values are displayed on the seven segment LCD. The microcontroller also processes the pushbutton switch selections for the LCD and stores the operating parameters in non-volatile memory. Stored parameters are only changed wit h the front pa nel switches a nd are unaffected by los s o f power or channe l reset. The microcont roller co ntinuously pr ocesses the loop samples and the detector operation is not affected during the operation of the switches or the LCD. (Note: When either channel’s sensitivity or frequency is change d, that channel is reset .)

In addition, the microcontroller conditions the out puts base d on Pha se G reen I nput s and t he pr ogra mmed sett ings of the various t imers (De lay, Ext ension, and Max Presence ) and opt ions (EO G, Optio n 3, Opt ion 4, Opt ion 5, Option 9, Option 10, and Option 12).

8.4 TROUBLESHOOTING INTERMITTENT LOOP FAIL PROBLEMS

Have you been able to see the channel display while the loop failure was occur ring?

NO, Loop Fail problems tend to be bad splices in the loop / lead-in c irc uit , sho rt s in t he loo p / le ad-in cir cu it, sh or ts t o earth ground in the loop / lead-in circuit, or loose connections or bad solder joints in the signal cabinet. If you ha ve an y splices that are not soldered a nd sealed with an adhes ive heat shrink or ep oxy resin, replace the sp lice with one that is. Using a MegOhm meter, measure the resist ance fro m one of the loop wires to earth gro und. It should be great er tha n 50 megOhms. Inspect the loop. Look for expo sed wires or debris pressed into the saw cut. Tighten a ll screw terminals in the signal cabinet that the loo p circuit uses. Check solder joints in the loop c ircuit, especially on the harness itself. Disconnect and reconnect a ny co nnecto r used in the loo p c ircuit and check for loo se pins a nd socket s in these connect o rs. If your cabinet has lightning or surge suppression devices on the loop inputs in the cabinet, remove or replace them. Check for places in t he field where the loop wire or lead-in cable may be pinched or chaffed. Look for wires pinched under junction box covers and where the wire enter s a conduit, especially where the loop wire leaves the saw cut and enters a conduit. After checking all of the above items, you could swap out the detector but this t ype of failure is rarely ever related to the detector.

YES, Did the display show L hi?

NO, The d ispla y must have been L lo the n. Th is ind icate s an int er mittent sho rted loop or -25% inductance

8.5 TROUBLESHOOTING INTERMITTENT DETECTOR LOCK-UPS

Have you been able to see the channel display while the loop was locked up?

NO, See Troubleshooting Intermittent Loop Fail Problems a nd fo llow t he pat h for u nable t o see t he cha nnel d ispla y while the loop failure was occurring.

YES, Were more than t wo segments lit in t he bar grap h on the LCD?

NO, Problems of this type tend to be difficult to isolate due to the many possible causes and the short duration

of the symptom (usually less than 30 minutes). If the problem occurs more frequently in the morning or when

raining, suspect a short to earth ground in the loop / lead-in cir cu it. T his can u sual ly be verif ied b y test ing

with a MegOhm meter but no t always. Vibrat ion can also be a possible cause. Loop wires may be moving

slightly in a conduit due to vibrat ions from truck traffic. Ut ility lids in t he street near t he loop may also be a

source of problems. Ensure that lids near a loop are bo lted down so t hat they cannot move. Check that each

set of loop wires is t wisted together in each pull box and t hat lengths are not excessive. And a lso see

8.7 THINGS TO KNOW ABOUT LOOPS

Always use a wire with cross-linked Polyet hylene insu lation (insulation type XLPE) for loo p wire. Typical sensing height is ⅔ of the shortest leg of a loop. Therefo re, a 6΄ x 6΄ loop will have a detection height of 4΄. The inductance of a conventional four-sided loop can be estimated using the formula: L = P x (T2 + T) / 4 Where: L = Loop Inductance in microhenrie s

P = Loop Perimeter in feet T = Number of Turns of Wire.

Therefore, a 6΄ by 6΄ loop with 3 turns would have an inductance of:

L = (6 + 6 + 6 + 6) x (32 + 3) / 4 L = 24 x (9 + 3) / 4 L = 24 x 12 / 4 L = 24 x 3

L = 72 microhenries. The inductance of a QuadrupoleTM loop can be estimated using the formula: L = [P x (T2 + T) / 4] + [CL x (T2 + T) / 4] Where: L = Loop Inductance in microhenries

P = Loop Perimeter in feet T = Number of Turns of Wire CL = Length of Center Leg in feet.

Therefore, a 6΄ by 50΄ loop with a 2-4-2 configuration would have an inductance of:

L = [(6 + 50 + 6 + 50) x (22 + 2) / 4] + [50 x (42 + 4) / 4]

L = [112 x (4 + 2) / 4] + [50 x (16 + 4) / 4]

L = (112 x 6 / 4) + (50 x 20 / 4)

L = (112 x 1.5) + (50 x 5)

L = 168 + 250

L = 418 micr ohenries. Loop Feeder cable typically adds 0.22 microhenrie s of inductance per foot of cable. Total inductance of loops connected in series: L Total inductance of loops connected in parallel: L

= L1 + L2 + L3 + . . . + LN.

TOTAL

= 1 / [ (1 / L1) + (1 / L2) + (1 / L3) + . . . + (1 / LN) ].
