Section 1 General Description

This product manual was written for people installing, operating, and maintaining the Reno A&E Model P-1400 inductive loop vehicle detector. The Mode l P-1400 is a four-channel inductive loop vehicle detector designed as a direct, drop-in replacement for older technology detectors that mount in ground level enclosures. It is designed to be used in applications requiring detection of railway vehicles in large detection areas typically required in classification yard switch and sidesw ipe protection, interlocking and movea ble bridge occupancy detection, or detection of roadway vehicles and/or railway vehicles in at-grade crossing sites.

The Model P-1400 monitors and process es signals from four loop / lead-in circuits, four check loop circuits, and one Vital input. These inputs can be pro grammed to co ntrol two Vital o utputs, one pr imary Vital o utput and one auxiliary Vital output. The primary Vital output ca n be controlled by any combination of t he four loop inputs and/or the Vital input. In addition to the four loop inputs and the Vital input (as described above), the a uxiliary Vital output can be controlled by the four loop Health Status inputs that are continuously monitored by the processor. A loop failure will deactivate the Vital output that the loop status input and/or loop Health Status input is programmed to control. The check loop circuits ca n be programmed to s imulate a vehicle detection (every 1 t o 255 minutes) in the loop area as a means of verifying p roper loop operatio n. T he Vital o utputs a nd Vita l input are monitored to ensure they are in the correct state. If the state of the Vital input is not correct, the front panel LED indicator will turn red and all Vital outp uts will be de act ivated. I f the sta te of e ither V ital o utput is not correct, t he front panel LED corresponding to that output will turn red and both Vital outputs will b e de a ctivated.

A Liquid Crystal Display (LCD ), seve n LEDs, and four f r ont panel pushb uttons a re used t o displa y and program all detector functions. The Model P-1400 also incorporates a series of motherboard and front panel mounted connectors to facilitate set-up and operation. Motherboard mounted Wago type connectors are used for detector input and output connections. A front panel mounted nine pin RS-232 co nnector is used for communication with a laptop computer.

The use of a LCD is one feature that disti nguishes this detector from that of other manufacturers. It a llows for more information, never before a vailable, to be displayed to the user during normal operat ion of the detector. Several diagnostic modes are available to aid the technician in troubleshooting detection problems. It also allows easy viewing and setting of all programmable values in the detector. The detector cont inues to operate normally while being programmed. An eight-se g me nt ba r gr a p h a t t he top of the LCD provides a graphical representation of the relative change of inductance as seen by the detector. This automatically takes into account loop size, loop inductance, number of loops, number of turns, geometry, lead-in length, etc. The firs t bar grap h seg ment repre s e nt s the minimum inductance change necessary for the detector to output a call. Larger inductance changes will be indicated by more segments. Each additio nal segment represents the next sensitivity le vel exceeded. Therefore, the bar grap h indicates if the se nsitivity is se t too high or too low, easily facilita ting the idea l setting of se nsitivity level.

All programmed settings are stored in non-volatile memory and can only be changed by programming new settings. Memory stora ge consists o f an internal EEPROM mounted on the processor board and an EEPROM mounted on the motherboard. Settings programmed on either compone nt must match those programmed on the other for the detector to operate. Loss of power or a detector reset will not change the programmed sett ings. If a loop failure occurs, the LCD will display the type of loop failure as L lo (for -25% change or shorted loop condit ions) or L hi (for +25% change or open loop cond itions). Eac h loop failure is counted ( up to a maximu m of 255 failures) and accumulated in the Loop Failure Memory. Information on the number of failures since t he last detector reset or power interruption is very useful during analysis of problems due to intermittent loop operat ion.

The Model P-1400 detector is a scanning detector. The scanning operation sequentially activates the on and off cycle of each detector channel’s oscillator. Because only one channel’s loop input(s) is (are) active at a given time, crosstalk between adjacent loops connected to the sa me scanning detector is minimized. Several Model P-1400 detectors can be linked together via the Synch In and Synch Out lines. This allows loops connected to different detectors to be scanned in series or parallel. When in Program Mode, t he Model P-1400 detector disp la ys t he re al time loop frequency reading for each channel. The eight frequency levels can be incremented or decremented to provide precise frequency settings. This re moves the guesswork when changing frequency sett ings to eliminate crosstalk. NOTE: Adjacent loops connected to different channels of a non-scanning detec tor or different sca nning detectors should be set to different frequencies with the maximum separatio n possible.

The Reno A&E Model P-1400 utilizes the first major innovat ion in inductive loop detectors since the introduct ion of digital detectors. The programming o f all of the detector’s parameters with four normally ope n pushbutton switches not only simplifies setup by removing binary coded rotary or DIP switches, but also increases the reliability of the detector by removing t he dependence on switch co ntacts during normal operation. T he detailed descriptions displayed on the LCD facilitate the interpretation of operational state conditions to determine the detector status.

Section 2 General Characteristics

2.1 LOOP FREQUENCY

There are eight selectable loop frequency settings ( normally in the range of 20 to 100 kilohertz) per loop input. The actual loop operating frequency is a function of the loop / lead-in network a nd the compo nents o f the lo op oscillator circuit. The digital display of t he actual loop operating frequency for each setting makes it easy to quickly identify and elimina te crosstalk in the most difficult to configure installations. The freque ncy display is typically very stable when the loop is vacant and vehicles are not passing close to the loops. If the reading is varying by more than ±1 in the last digit, this is an indication of possible crosstalk between loops.

2.2 SENSITIVITY

There are ten selectable sensitivit y levels per loop input, plus Continuous-Call a nd Loop-Off. The sensiti vity levels are designed so that a one level increase actually doubles the sensitivity and a one level decrease halves the sensitivity. A unique bargraph displayed on the LCD makes it easy to quickly set sensitivity at the ideal level for any loop / lead-in network situation. (See Section 3.4 for actual detection levels at each sensit ivity level.)

ONTINUOUS-CALL: When set to the Co ntinuous-Call state, the Loop Status is continuo usly in the Call state

regardless of the presence or absence of vehicles over the loop. If the Loop Status Input is assigned to a Vital Output , the Cont inuo us-Call state w ill deactivate the V ital Output. The loop oscilla tor is disa bled when in the Continuous-Call State. This state is indicated by Call flashing on the LCD. This option can be selected from the Sensitivity menu in Progra m Mode a nd is useful for checking contro ller response and other t roubleshooting activities.

OOP-OFF: When set to the Loop-Off state , the Loo p Stat us is con tinuo usly i n the No -Call state regardless of

the presence or absence of vehicles over the loop. If the Loop Status Input is assigned to a Vital Output, the Loop-Off state will not affect the Vital Output. The loop oscillator is disabled when in the Loop-Off State. This state is indicated by OFF flashing on the LCD. This option can be selected from the Sensitivity menu in Program Mode and is useful for checking controller response and other troubleshooting activit ies.

2.3 OPTION 1: LOOP INDUCTANCE DISPLAY

The Loo p I nd uc tance Dis play set t in g c a n be toggled ON or OFF by mome nt a rily pre s s in g e it her the  (UP) or  (DOWN) pus hbu tto n. W hen t his opt io n is enab led ( ON), the LCD dis pla ys t he t ota l lo op inductance (actual loop inductance plus actual lead-in inducta nce) in microhe nries fo r loop ind uctanc e values in the ra nge of 20 to 25 00 microhenries. By recording the inductance of the loop / lead-in circuit when it is first installed, 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 8.2 of this manual. NOTE: Enabling this option activates it for all loop inputs. This option is automatically disabled 15 minutes after activation or on loss of power.

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

The Loop Inductance -ΔL/L Display setting can be toggled ON or OFF by mo mentari ly press ing eit her the  (UP) or  (DOWN) pushbutton. When this option is enabled (ON), the LCD displays the percentage of induct ance cha nge (-ΔL/L value) during the Ca ll state. To facilitate the viewing of the maximum amount of change in the -ΔL/L value while traffic is in motion over the detection zone, the channel holds the peak -ΔL/L value for a period of two seconds. NOTE : Enabling this option activates it for all loop inputs. T his option is automatically disabled 15 minutes after activation or on loss of power.

2.5 OPTION 3: NOISE FILTER

Each loop input’s Option 3 has four settings ranging from 3.00 to 3.03. When Optio n 3 is set to 3.00, the option is disab led (OFF), a nd normal noise filtering is used. W hen Option 3 is set to 3.01, 3.02, or 3.03 the option is ON, and increased filtering of the loop signa l is used to eliminate problems assoc iated with particular types of noise. Turning this option ON when not required can degrade the performance of the detector. The default setting o f t his option is 3.00 (OFF). This op tion should only be turned ON at the advice of Reno A&E. NOTE: Each loop can be enabled independently.

3.00 = 250 milliseconds filter.

3.01 = 1 second filter.

3.02 = 2 seconds filter.

3.03 = 10 seconds filter.

2.6 OPTION 4: DETECTION ZONE TRACKING

Each loop input’s Option 4 has nine settings ranging from 4.00 to 4.08. This option allows the user to select a detection zone tracking setting that will maintain detection zone occupancy for an extended period of time. When Option 4 is set to 4.00, the detector will t rack ou t the vehic le (i.e. drop the detection of the vehicle) in four minutes to several hours depending on the amount of inductance chan ge (-ΔL/L) caused by the vehicle when it is detected. The greater the change caused by the vehicle, the longer the time needed to track out the vehicle. When Option 4 is set to 4.01,

4.02, 4.03, 4.04, 4.05, 4.06, 4.07, or 4.08 the option is ON, and the detector wil l provide e xtended detection times.

There are man y fac tors tha t in flu ence t he p roper s ett in g of this op tion. A full expla nat ion of h ow to determine the correct setting is beyond the scope of this manual. Contact a Technical Support representative at Reno A&E regarding proper settin g of this option.

NOTE: Using this option in a long loop application is not recommended. The detector will drop the call prior to the vehicle totally exiting the loop.

4.00 = Tracki ng R ate 0.

4.01 = Tracki ng R ate 1.

4.02 = Tracki ng R ate 2.

4.03 = Tracki ng R ate 3.

4.04 = Tracki ng R ate 4.

4.05 = Tracki ng R ate 5.

4.06 = Tracking Rate 6.

4.07 = Tracki ng R ate 7.

4.08 = Tracki ng R ate 8.

2.7 OPTION 5: SENSITIVITY BOOST

Each loop input’s Option 5 has five settings ranging from 5. 00 to 5.04. W hen Optio n 5 is set to 5. 00, the opt ion is disab led (OFF), a nd no sensitivity boost is added. W hen Option 5 is set to 5.01, 5.02, 5.03, or 5.04 the option is ON, and sensitivity boost is enabled. A fter detect ion, the se nsitivity is boosted to t he currently se lected se nsitivit y level p lus the nu mber of le vel(s ) select ed. The maximu m sens itivit y level that ca n be ob tained w ith or witho ut sensitivity boost is level 10.

5.00 = Off (no sensitivity boost).

5.01 = 1 level of sensitivity boost.

5.02 = 2 levels of sensitivity boost.

5.03 = 3 levels of sensitivity boost.

5.04 = 4 levels of sensitivity boost.

2.8 OPTION 6: AUDIBLE DETECT SIGNAL

Each loop input’s Audible Detect Signa l setting can be toggled ON or OFF by mome nta r ily p re ss i ng e ithe r the  (UP) or  (DOWN) pus hbutton. Only one loop input can be turned ON at a t ime. T ur ning this option ON for o ne loop i nput auto matica lly turns it OFF for the other loop inputs. When this option is enabled (ON), an audi ble signal will be activated whenever the detection zone for the selected loop input is occupied. The audible signal indicates actual occupancy of the loop detection zone. This feature allows a technician to watch the detection zone and confirm correct detector operation without having to look at the detector disp lay as well. NOTE: This option is automatically disabled 15 minutes after activation or on loss o f power.

Page 10

2.9 LOOP CHECK

The Loop Check feature provides a means of auto matically verifying the proper operation of each loop circ uit. The Loop Check Timer can be set for an interval ranging from 0 to 255 minutes in o ne-minute increments. A setting of 000 indicates that the Loop Check feature is off.

2.10 DETECTOR ID

This feature is used in conjunction with the Synch feature (Option 7) and is also used as a means of providing each detector with a unique identification s ignature for communication purposes . Detector ID settings can range from 000 to 255. If, however, t he detec tor is set to an ID value of 255, it is co ns idered to be in an uninitialized state a nd the detector will not save any power down data. When a detector with an ID setting of 255 is powered up, the LCD will alternate betwee n id and 255 until the ID setting is changed to something other than 255 and the new setting is saved in detector memor y. Whe n a ny detecto r is first initialized, its ID setting is, by default, 255.

2.11 OPTION 7: SYNCH FEATURE

This option provides a means o f linking together up to four (4) P-1400 detectors. Each detector’s Option 7 has three settings ranging from 7.00 to 7.02. T here are two modes of Synch, Ser ies Synch and Para llel Synch. W hen set to operate in Series Synch mode, one detector channel in the entire detector system is active at any given time. This has the advantage of minimizing crosstalk between adjacent loops connected to different P-1400 dete ctors. When se t to o perate in Parallel Sync h mode, all detectors scan their respective channel 1, 2, 3, or 4 inputs at the same time. Parallel Synch offers a faster response time than Series Synch, however the potential for crosstalk is greater.

7.00 = Off.

7.01 = Series Synch.

7.02 = Parallel Synch.

NOTE: When operating in either Series or Parallel Synch mode, all linked detectors m ust have Option 7 set to the same setting.

2.12 OPTION 10: INVERTED VITAL OUTPUT

The detector’s Inverted Vital Output option can be toggled ON or OFF by momentarily pressing ei ther the  (UP) or  (DOWN) pushbutton. When Option 10 is enabled (ON), the Auxiliary Vita l Output will assu me the state opposite to that of the Primar y Vital Output. When the Primary Vital Output de activates, the Auxiliary Vital Output will activate. When the Primary Vital Output activates, the Auxiliary V ita l Output will deactivate.

Loop failures or loop check test failures w ill deactivate the Primary V ital Output and activate the Auxilia ry Vital Output. If either Vital Output fa ils its self-check, both of the detector’s Vital Outputs will be deactivated and remain deactivated until the problem is corrected and the detector is reset rega rdless of the setting of Option 10.

2.13 PRIMARY VITAL OUTPUT DELAY

The Primary Vital Output ca n be condition ed with a Delay ti me that is adjustable from 0.0 to 25.5 s econds in 0.1second steps. Primary Vital O utput Delay time sta rts counting dow n when a Call state is received fro m the Loop Status Inp ut o r Vit al I np ut tha t is mapp ed t o the Pr ima ry Vital Output. When the timer reaches zero, the Primary Vital Output is deactivated. Primary V ital Output Delay does not condition the Auxilia ry Vital Output.

2.14 PRIMARY VITAL OUTPUT EXTENSION

The Pr i ma r y V i t a l O u t p ut c an be co ndition e d with an E x t e nsion ti me tha t is adjustab le from 0.0 to 25.5 sec onds in

0.1-second steps. Primary Vital Output Extension time starts counting down when a Call state is cleared from the Loop Status Input or Vital Input that is mapped to t he Primary Vital Output. The Primary Vital Output will remain off until the Extension time reaches zero. Any vehicle enter ing the loop detect ion zone during the E xtension time period causes the Primary Vital Output to remain in the off state, and later, when the last vehicle clears the loop detection zone, the full Primary Vital Output E xtension time starts count ing down again. Primary V ital Output Extension does not co ndition the Auxil iary Vital Output.

2.15 INPUT / OUTPUT MAPPING

The Loop Status Inputs and/or Vital Input can be assigned to either or both of the Pri ma ry Vital and Auxiliary Vital Outputs. Health Status can only be mapped to the Auxiliary Vital Output.

2.16 FULL RESTORE TO FACTORY DEFAULT SETTINGS

Pressi ng a ll fo ur fr o nt pa ne l pus hb ut to n s wit c hes s imu lta ne o us ly a nd co nt inu o us ly f or f ive (5) seconds restores all factory default settings. The countdown of the five se cond period is displayed on the LCD. Releasing any or all of the switches before the countdown ends aborts t he full restore operation. (See Section 3.5 for default settings). Refer to Section 5.0 for details. Caution: Restoring the factory default settings will clear all previously

programmed settings including any mapped output(s).

2.17 DIAGNOSTIC FEATURES ACTIVATION

When the detector is operating in normal mode, pressing either the  (UP ) or  (DOWN) pushb utton will temporarily activate Option 1 (Loop Inductance Display) and Opt ion 2 (Loop Inductance -ΔL/L Display) for all loop inputs and Option 6 (Audib le Detect S ignal) for the loop input ind icated in the lower port io n of the LCD. All three of these diagnostic options will remain active for 15 minutes.

2.18 PASSWORD PROTECTION

This detector has a password protection feature to gua rd against the accidental change of detector settings. In order to change any detector setting, a va lid password must be entered to disable the password protection feature. Refer to Section 5.0 for details.

OOP (FAIL) MONITOR: If the total inductance o f a channel’s loop input network goes out of the range specified for

the dete ctor , or rap idly c hanges by mo re tha n ±25%, and the Loop a nd/o r Healt h Stat us outp uts a re mappe d, the Loop and/or Health Sta tus outp uts will immediate ly enter Fa il-Safe mode and the LCD will display LOOP FAIL. The type of loop failure will a lso be displayed as L lo (for -25% change or shorted loop conditions) or L hi (for +25% change or open loop conditions). T his will continue as long as t he loop fault exists. At the time of a loop failure, the Loop status LED will begin to flash at a ra te of three flashes per sec ond. The LED will contin ue this display pattern until the loop input channel is manually reset or power is re moved. If the loop self-heals , the LOOP FAIL mess age o n the LC D will e xtin guish a nd the loop input channel will resume operation in a normal manner; except the Loop stat us LED will continue the three flas hes per second display patter n, thus provid ing an alert that a prior Loop Fail condition has occurred. Each loop failure for the loop input c hannel 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) can be seen by stepping through the loop input channel’s detector functions in Program Mod e to the LOOP FAIL mess age. When the status of one or mo re loops is assigned to a Vital Outp ut, a loop failure will deactivate t he Vital Output and the correspo nding VITAL OUT LED will turn from green to OFF to indic ate the failure. When a Health Sta tus is assigned to the Auxiliary Vital Output, a loop failure will deactivate the Auxiliary Vital Output and the VITAL AUX LED w i ll turn off.

OOP CHECK: This feature is used as a means of verifying proper operation of each inductive loop connected to a

detector. In a typical installat ion, a separate loop of wire called a check loop will be wound around the perimeter of each inductive loop. The Loop Check T imer can be programmed with a value ranging from 1 to 255 minutes. Once this time interval has elapsed, the detector will automatically short the check loop simulating vehicle detection in the induct ive loop. If this initial loop check test fails, t he detector will enter a verification mode to make certain that the loop failure is indeed due to a loop related problem. W hile operating in this verification mode, the detector will perform a series of ten verification tests and the LCD will flash Pcl. If the te n loo p c hec k verification tests all fail, the Vital Output(s) to which the Loop Status I nput(s) and/or Health Status Input(s ) is (are) mapped will be deactivated. The loop check test w ill be repeated at regular intervals depending on the value programmed into the Loop Check Timer. The Vital Output(s) to which the Loop Status Input(s) and/or Health Status Input(s) is (are) mapped will not be activated until t he problem with the check loop is corrected and the channel reset or until the Loop Check functio n is turned off. During a check loop failure the LCD will flash Lcl. NOTE: If the Loop Check Timer is set to 0 minutes, the Loop Check function is off.

YNCH MODE: The Synch feature provides a means of linking up to four P-1400 detectors together. There are two

modes in which the detectors can be configured to operate, Series Synch or Parallel Synch.

Series Synch mode can be used to eliminate the possibility of crosstalk between adjacent loops. Se ries Synch will activate one loop at a time, c ycling through all loops config ured to detect in the Series Synch mode. When the detector system is configured to operate in Series Synch mode, it is necessary for one detector to be identified as the master unit, i.e. the detector that starts the Synch pulse. This master unit must be assigned a Detector ID value of 000. The scanning sequence of detector loop input channels is Detector ID 000 channel 1, Detector ID 000 channel 2, Detector ID 000 channel 3, Detector ID 000 channel 4, second detector channel 1, second detector channel 2, second detector channel 3, second dete ctor channe l 4, a nd so on until the s ynch p ulse returns to the first detector. The Synch-out of the first (master) unit is connected to the Synch-in of the second detector; the S ynchout of the second detector is connected to the Synch-in of the third detector. This connection scheme is continued until the Synch-out of the last detector is connected to the Synch in of the first (master) detector.

When set to operate in Parallel Synch mode, all detectors configured to operate in Parallel Synch mode start scanning their respective channel 1 loop inputs at the same time and t he n proceed to sequentially scan their respective channel 2, 3, and 4 loop inputs. W hen the detector system is configured to operate in Parallel Synch mode, it is necessary for one detector to be identified as the master unit. This master unit must be assigned a Detector ID value of 000. Connections between detectors differ from those in Series Synch mode in that the Synch-o ut o f first detector is connected to the Synch-in of the othe r d e te c tors and t he S y nc h-in of the first detector is connected to the Synch-out of the other detectors.

Operation in either Synch mode requires that the Reset inputs (on the motherboard) of all detectors be tied together and that the DC - inputs (on the motherboard) of all detectors be tied together. To start operation in either Synch mode, the detectors must be reset using the Reset terminal on the motherboard.

When operating in Series Synch mode, if any detector fails to Synch, all o f the Vital Outputs of e very detector configured to operate in Synch mode will be deactivated. If the detector that has fai led to Synch has the Synch feature turned off, the other detectors confi gured to operate in Synch mode will continue to operate in Series Synch mode.

Section 5 Installation and Set-Up

Mount P-1400 in the enclosure (see diagra ms below). Connect 12 VDC power, Loops, Check Loops, the Vital Input, and the Vital Outputs to the terminals marked on the motherboard as de tailed below and apply power. If a loop is not connected to a loop termina l, the detector w ill see a failed loop and deact ivate the Vita l Output if it is mapped. The Loop Status for loop inputs with no loop connected must be turned off (see Sensitivity) or not assigned (mapped) to a Vital Output (see Vital Output Mapping). If the detector is not new from the factory, it may be advantageous to restore all factory default settings to avoid having to check every setting for e very loop input channel. To restore a ll factory default settings, d isable the pass word protection feature as explained be low. Press a nd hold all four pushbutton switche s simultane ously for fi ve seconds. When all four pushbutt ons are depressed and held, the display will start counting down fro m five (5). When the countdown reaches zero (0), releasing the pushbuttons restores the factory default settings. Releasing any or all of the switches before the countdown ends aborts the full restore operation. Cautio n: Restoring the factory d efault settings will clear all previously programmed settings including any mappe d output(s).

All operating parameters can be adjusted from the front panel. The detector continues to operate norma lly 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 changing the delay time, the time displayed at the instant that a vehicle entered the detection zone for that loop input channel would be the value used fo r the delay timer .

Pressing the FUNC pus hbutton e nters t he Prog ram Mode . The FUNC p ushbutto n has an auto r epeat funct ion. This allows quick navigation to the desired parameter. The FUNC pushbutton only moves forward through all of the parameters. There is no way to move backwards through the parameters.

While viewing any parameter, pressing the CHAN p ushbut ton wil l disp lay the same p aramete r in t he next l oop input channel. The currently selected channel is indicated at the bottom of the LCD display. Pressing and holding the CHAN p ushb utton for one sec ond will exit the Program Mode and return to the Normal Mode.

Pressing and holding either the  (UP) or  (DOWN) pushbutton will ca us e the va lue t o c hange ra p id l y u nt i l the pushbutton is released.

Disabling Password Protection

To change any detector setting, the password protection feature must be disabled. When viewing a setting in the Program Mode, press the  (UP) or  (DOWN) pushbutton to ente r pa s s word entry mode. The LCD will d is play PSd to provide an indication that a valid password must be entered before any detector sett ing can be changed. NOTE: Pressing the CHAN button for two seconds at an y time will e xit password entry mode . P re ss the  (UP) or  (DOWN) pushbutt on. The LC D displa y will cha nge to 000 with the leftmos t 0 flashing. Press the  (DOWN) pushbutton t o change the fl ashing digit t o 9. Press the CHAN pushbutton a second time to ge t the ce nter 0 to flash. Press the  (UP) pushbut ton to change the flash i ng digit t o 1. Press the CHAN pushbutton a third t ime to get the rightmost 0 to flash. Press the  (UP) p ushbutton to change the flas hing digit to 1. Press the FUNC pushbutton to enter the password. Detector settings can now be c hanged. Press the FUNC pushbut t o n t o e nt e r t he password. Detector settings can now be changed. Password protection can be re-e nabled by pressing and holding the CHAN p ushbutt o n fo r t w o s ec onds followed by pressing the  (U P ) pushbut t o n t wic e . If n o a ction is ta ken to re-enable the password protection feature, it will be automatically re-enabled 15 minutes after changing any detector setting.

LOOP FAIL

The detector will next confirm the state of the check loops connected to it. If a ll four check loops are connected and are intact, the LCD screen will display an indication of the successful completion of the check loop verification. This screen will flash twice.

If all four check loops are not connected or one (or more) is (are) damaged in some way, the detector will initiate its check loop verification proce ss. The LCD screen will display an indication of a pending state during the che ck loop verification. This screen will flash for 55 seconds until one of three things happe n; the check loop ver ification fails, the c heck loop(s) causing the check loop verification is (are) connected or restored to a functional state, or the check loop(s) causing the check loop verification is (are) turned off, i.e. the Loop Check Timer of the loop(s) is set to 000.

If the check loop verification process continues for the entire 55 second period and no action has been taken to connect or restore the check loops causing the check loop verification, the LCD screen will toggle between the two screens shown w ith a 50% duty cycle.

If the detector passes its check loop verification process or a pending loop check failure state is resolved in one of the ways mentioned above, the LCD screen will show a normal (idle) condition.

5.4 ERROR MESSAGE DISPL AY SCREENS

The Model P-1400 stores operating parameters and detection reference settings in two places. The detector hardware includes an internal EEPROM mounted on the processor board and an EEPROM mounted on the motherboard.

Logic programmed into the detector operating firmware continua lly checks the data stored on the two compone nts listed above. This check function provides a means of verifying several key factors that ensure that the detector is functioning properly. Thes e includ e:

Detector power up status - Has the detector powered up correctly and is it operating in the correct state? Detector Failure status - Are failure conditions be ing identified and is the detector res ponding to these failures

correctly? Stored data status - Is the data stored on each o f the two data storage components consistent with each other?

If the information obtained via the check function ind icates that there is a problem with some phase of the detector operation, the LCD screen will display one or more of the error messages listed below.

Uninitialized Motherboard Mounted EEPROM . The display will toggle between the two screens shown with a 50% duty cycle. This is an indication that the motherboard mounted EEPROM is uninitialized. To correct this problem, press the FUNC pus hbutto n. If the e rror mess age does not clear, the motherboard mounted EEPROM is defective. Return the detector to the factory for servicing.

Warning: If the error message clears after pressing the FUNC pushbutton, the us er must confirm that t he stored detector setti ngs are correct for the installation in questio n.

Uninitialized Interna l E EPROM. The display will toggle between the two screens shown with a 50% duty cycle. This is an indication that the internal EEPROM is uninitialized. To correct this problem, press the FUNC pushbutton. If the error message does not clear, the internal EEPROM is defective. Return the detector to the factory for servicing.

Warning: If the error message clears after pressing the FUNC pushbutton, the us er must confirm that t he stored detector settings are correct for the installation in questio n.

Uninitialized Internal and Motherboard M ounted EEPROMs. The display will toggle bet ween the two scr eens sho wn with a 50% dut y cycle. This is an indic ation that t he interna l EEPROM and the motherbo ard mounte d EEPROM are uninitialized. To correct this problem, press the FUNC pushbutton. If the error message does no t clear, the internal EEPROM and the motherboard mounted EEPROM are defective. Return the detector to the factory for servicing. NOTE: Clearing this error message will reset the detector to factory default settings and will clear any previously mapped output(s).

Warning: If the error message clears after pressing the FUNC pushbutton, the us er must confirm that t he stored detector setti ngs are correct for the installation in questio n.

If the error message does no t clear, the internal EEPROM and the mot herboard mounted EE PROM a re defective . Return the detector to the factory for servicing. NOTE: Clearing this error message will reset t he detector to factory default s ettings and will clear any previously mapped output(s).

Warning: If the error message clears after pressing the FUNC pushbutton, the us er must confirm that t he stored detector setti ngs are correct for the installation in question.

Detection Reference Error. This is an indication that the internal EEPROM and the motherboard mounted EEPROM detection reference values do not match. Press the FUNC pushbutton to clear the error message.

Warning: If the error message clears after pressing the FUNC pushbutton, the user must confirm that the stored detector s e ttings ar e c or r e ct for the ins tallation in question.

Warning: Clearing this error will reset all internal and external detection reference values. If a vehicle (or vehicles) is (are) present over any or all loops at this time, the inductance change caused by the vehicle(s) will be incorporated into the new baseline detection reference and the vehicle(s) will no longer be detected.

5.5 LOOP CHECK PASS / FAIL INDICATIONS

The Loop Check feature is enabled whenever the Loop Check Timer for a specific loop input is set to a value between 1 and 255 minutes. When the Loop Check T imer has timed out, the detector will automatically short the check loop to simulate vehicle detection. If the percentage of inductance change is greater than or equal to -0.04% ∆L/ L, and the channel on which the current loop check test is selected and being viewed on the LCD, the display will show PAS.

Loop Check

1 Loop Check

If the percentage of inductance change caused by activating the check loop is less than -0.04% ∆L/L, the detector will initiate its check loop verification process. The LCD screen will displa y a n ind icat io n of a pe ndi ng st ate (Pcl) during the check loop verification. This scree n will flash for 55 seconds until one o f three things happen; the check loop verificat ion fails (indic ati on s how n be low - Lcl), the check loop(s) causing t he check loop verificat ion is (are) connected or restored to a functional state (indication shown above, PAS), or the check loop(s) causing the check loop verificat ion is (are) turned off, i.e. the Loop C heck Timer of the loop(s) is set to 000.

Pending Indication

If the check loop verification fails, the LED corresponding to t hat loop channel will begin flashing at a three Hz rate. If the channel corresponding to the check loop failure is selected and being viewed on the LCD, the display will toggle between a screen showing L and LOOP FAIL and a scree n showing Lcl and LOOP FAIL wit h a 50% dut y cyc le to indicate a that Loop Check failure has occurred. In addition, the loop status will enter the Ca ll state and the Health Stat us will enter the Fail condition.

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 termina l 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.

5.15 CHANGING PROCESSOR BOARD OR MOTHERBOARD

The P-1400 dete ctor stores use r-progra mmed para meters o n an internal EEPROM mounted o n the p rocessor boa rd and on an EEPROM mounted on the motherboard. This allows the user to change the processor assembly or motherboard and reset the parameters that were programmed for that particular site. When a new processor assembly or motherboard is installed, an Error message will appear on the LCD. The LCD will alternate between Cpy and In. This message means that the parameters stored on the motherboard mounted EEPROM do not match the parameters stored on the EEPROM on the processor board. If the motherboard was replaced, pressing the FUNC pushbutton will accept the para mete rs s tored on the EEPROM on the processor board and store them on the motherboard mounted EEPROM.

Section 7 Theory of Operation

The Re no A&E M od el P -1400 detector digitally meas ures changes in the resonant frequency of four independent loop circuits to determine if a vehicle has entered the detection zone. The Model P-1400 detector applies an excitation voltage to each loop circuit resulting in the loops oscillating at their reso nant frequencies. The current flow in the loop wire creates magnetic fields around the loop wire. When a vehicle passes over the loop area, the conduc tive meta l o f 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 freque ncy, the magnitude and rate o f change c an be determined. If the frequency change exceeds a selectable threshold (set by the sensitivity settings), the detector will deactivate a Vital output if one is mapped. If the rate of change is slow, typical of environ mental drift, the detecto r will cont inuously track and compensate for the change. The Model P-1400 detector also monitors the loop frequency for out of range conditions such as an open or shorted loop circuit.

The Model P-1400 detector is a scanning detector. The scanning method sequentially turns on and off eac h channel’s loop oscillator. Each channel’s osc illator circuit supplies t he excitation voltage that is coupled to the loop circuit by a loop isolation transformer. The tra nsformer provides high common mode isolation between the loop and detector electronics, which allows the detector to opera te on poor qualit y loops including a single s hort to ground. The transformer also limits the amount of static energy (lightning) that can transfer to the detector electronics. A spark gap transient suppression device is connected across the loop inp uts co nne cted to the isolation transformer. This device dissipates static charges prior to 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 osc illator circuit thus providing frequency separation be tween adjacent loops. The three switchable capacitors are electronically switched using FETs and are selected when programming parameter value s with the front p anel pushbutton 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 allowing only a single loop oscillator to be operating at a ny given time. The sine wave from each loop oscillator circuit is squared to provide a prec ise zero crossing signal for the input to the microcontroller. This signa l is called the loop sample. The loop sample is an integral number of complete oscillations from the loop oscillator circuit. The number of loop oscillatio ns counted is a function of the selected sensitivity setting for the detector 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) crystal clock p ulses generated by the microcontroller’s internal 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 vehic le ente rs t he loop zone t he l oop ind ucta nce de creases. This decrease in loop inductance causes an increase in the loop oscillato r 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 cr ystal 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. If the magnitude of the change exceeds a selectable threshold (sensitivity setting), the detector deactivates a Vital output if one is mapped. The rate of change is also monitored. Slow rates of c hange caused by environmental fluctuations are tracked and automatically compensated for. This process is conducted independently for each of the four loop oscillator circuits.

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 seve n-segment LCD. The microcontroller also processes the pushbutton switch selections for the LCD display and stores the operating parameters in non-volatile memory. Stored parameters are changed with the front panel switches or via the front panel RS-232 communications port and are unaffected by loss o f power or detector reset. The microcontroller continuously processes the loop samples and detector operation is not affected during the operation of the switches or the LCD. NOTE: When eit her the sensitivity or frequency of a loop input channel is changed, the loop input cha nnel is reset.

In addition, the microcontroller conditions the outputs based on Loop Status Inputs, Vital Inputs, Health Status Inputs , and the p rogramme d settings of the va rious ti mers (Prima ry Vita l Output De lay, Pri mary Vital O utput Extension, and Loop Check) and options (Option 1, Option 2, Option 3, Option 4, Opt ion 5, Option 6 and Option

7).

Section 8 Maintenance and Troubleshooting

The Reno A&E Model P-1400 Detector requires no maintenance. If you are having problems with your Mode l P1400 detector, use the troubleshooting tips below to help determine the cause of the prob lem.

8.1 BASIC TROUBLESHOOTING TIPS

Detector Enclosure Checks:

Verify correct input voltage to the detector. Check the detector diagnostics. If there is a current loop failure or the loop fail memory shows a loop failure has

occurred, the problem is probably not related to the detector module. Check the loop / lead-in cable resistance of the detect loops and the check loops. A value greater t han five

Ohms is an indication of a splice or connection problem or a broken loop wire. Disconnect the detect loop or check loop from the detector. Use a 500 VDC Megger to measure the resistance

from one of the loop wires to earth ground. It should be greater than 50 megOhms. If lower, separate the splice at the pull box and isolate the problem to the loop or lead-in cable.

Verify all terminal screws are tight. Inspect all loop connections in the detector enclosure, especially crimped lug connections. If suspect, solder the

lugs to the wire. If the lightening or surge suppression devices on the loop inputs in the detector e nclosure are s uspect, remove or

replace them. Check for places in the detector enclosure where the harness wires or lead-in cable may be pinched or chaffed. Make sure that each pair of interconnect (lead-in) wires for the loop(s) are individually twisted together.

Field Checks:

Inspect the loop. Look for exposed wires, debris pressed into the loop wires, paveme nt s hifts , e tc . Check splices in the pull box. They must be soldered and waterproofed. DO NOT USE WIRE NUTS. Check that each set of loop lead-in wires in each pull box is twisted to gether [six (6) twists per foot, minimu m]

and that lead-in lengths are not excessi ve.

8.2 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. Therefore, 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 microhenries

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

Therefo re, 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 (T

P = Loop Perimeter in feet TOL = Number of Turns of Wire (Outer Legs) T CL = Length of Center Leg in feet.

+ TOL) / 4] + [CL x (T

+ TCL) / 4] Where: L = Loop Inductance in microhenries

= Number of Turns of Wire (Center Legs)

Therefo re, a 6΄ by 50΄ loop with a 2-4-2 config uration w ould 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.
