FIRMWARE VERSION
The fir mware ver sion and r evisio n for the de tector is displaye d. This is a view o nly para meter. Th e displa y alterna tes
between the model letter and firmware version (example U34) and the firmware revision number (example .00).
III. How to Reset the De tector:
• Momentarily press the CHAN pushbutton until the channel to be reset is selected. Press and hold the CHAN pushbutton
continuously for three (3) seconds. After three seconds the channel is reset maintaining all previous settings.
• Changing the freque ncy or se nsit ivit y sett ing w ill en ter t he new s ett ing a nd res et the cha nnel. Chan ging any o f the ot her
parameters will take e ffect immed iately or on the next de tection, but will not rese t the detec tor channe l. Sim ply enter ing
the program mode wit ho ut changing any parameter will not reset the channel.
• Pressing and holding all four pus hbu ttons simultaneously and continuously for five (5) seconds re sets both c han nels a nd
also restores the default settings to both channels.
• Changing the setting of Option 4 (Noise Filter Disable) will reset both detector channel s .
• The detector can be reset by removing and reapplying power.
• Loop Fail History is cleared by all rese t procedures descr ibed above excep t changing t he setting of Option 4 or changing
freque nc y o r s ens it iv it y. Press ing either the
(UP) or (DOWN) pushbutton while viewing the Loop Fail Histor y will
also clear the Loop Fail History.
IV. Sensitivity Setting:
Sensitivity is controlled by selecting a Sensitivity Level for each c hannel. The sens itivity settings o f 1 through 9 represent
thresholds from the least sensitive to the most sensitive. Setting the proper sens itivity level for the loop circuit provides
stability to the system. If set too high, the de tector may detect adjacent traffic. If set too low, t he detector may not detect
small vehicles or high bed vehicles.
The LCD includes an eight (8) segment bargraph that is a representation of the relative change of inductance as seen by the
detector. This automatically takes into acc ount loop s ize, loop inducta nce, number of loops, number of turns, loop geometry,
lead-in length, etc. The bargraph is a sliding scale that is relative to the programmed Sensitivity Level. The first (left-most)
bargraph segment represents the minimum inductance change necessary for the detector to output a call at t he currently
selected sensitivity level. Larger inductance changes will indicate more segments. Each additional segment indicates that the
next se ns it ivi ty le ve l has a lso b ee n met o r e xce ede d. Therefore, the bargraph indicates if the sens itivity is set too high or too
low, easily facilitating the idea l sett in g of the sensitivity level.
The dia gra m belo w sho ws the bar graph w it h the c hanne l set to Sensitivit y Level 6: 0.02% -ΔL/L. The bargraph indicates
that the vehicle in the loop zone has exc eeded the mi nimum sens itivity leve l by an additio nal five Sens itivity Leve ls or
0.64% -ΔL/L. The typical vehicle to be detected should cause five or six segments of the bargraph to become filled.

If the typical vehicle to be detected is not creating a five to six segment display on the bargraph, count how many segments
are being displayed and subtract six. If t he number is positive, lower the sensitivity that many leve ls. If t he numbe r is
negati ve, rais e t he se ns itiv ity t hat man y le vels . E xamp le: The d ete cto r cha nne l se ns itiv ity is c urre nt ly pr ogr am med at th ree
(3). The bargraph shows four (4) segments during a typical vehicle detection. Take four (4) (the number of segments
displayed) and subtract six (6) to get minus two (-2). Si nce the a nswer is negat ive, raise the sensit ivity level, c urrent ly at
three (3), by two (2) to arrive at the desired s e nsitivity level of five (5 ).
The bargraph can also be used to take advantage of a direct relationship between the percent change of inductance caused by a
single standard automobile and a small motorcyc le in the sa me loop / lead-in conf i gurat ion. Ad justin g the se nsitivi ty level for
the channel until seven (7) segments of the bargraph are shaded when a standard auto mobile is present in the loop zone
ensures that the sensitivity has been set to detect a small motorcycle in the same loop zone. If the left most segments of the
bargraph are flickering when vehicles pass in t he adjacent lane, the Phase Green Compensation can be turned on to minimize
the effects of adjacent lane detection (see Option 5). The second method of reducing adjacent lane detection is to reduce the
sensit ivit y leve l by t he nu mber of seg ment s tha t are flickering, however this w ill also eliminate the ability to re liably detect
small mo t o rcycles .

the functions described below.
• Pres s t he CHAN p ushbutt o n t o s e le c t the cha n ne l to vi e w o r ma ke cha nge s t o. T he c hannel t ha t is in PR O G R AM mo d e is
indicated by a flashing numbered-loop symbol at the bottom of the LCD.
• To change a function’s setting or to toggle a function ON or OFF, press the (UP) or (DOWN ) pushbutton.
• To exit the PROGRAM mode a nd return to the NORMAL mode, press and hold the CHAN p ush butto n continuously for
one second.
LOOP FREQUENCY
Press the (UP) or (DOW N) p us hb utt on to c han ge t he pro grammed l oop fre q ue ncy. The fil le d se gme n t on t he bargraph
indicates the setting. The left-most segment represents setting 1 a nd t he rig ht-mo st se gme nt represe nts setting 8. The LCD
will display the actual operating frequency of the loop circuit. A separation of at least 5 KHz for adjacent loops, not
connected to the same detector, is recommended. NOTE: Changing the frequency will reset the detector channel. Care
should be taken to ensure that the detector channel is not reset while the detection zone is occupied.
SENSITIVITY
Press the (UP) or (DOWN) p ushbutton to change the programmed sensitivity. The low e s t S e nsitivi t y Le vel is 1 and the
highest Sensitivity Level is 9. The channel can be configured to place a permanent call by selecting CALL (o ne setting after
Sensitivity Level 9). The channel can be disabled by selecting OFF (one setting before Sensitivity Level 1). If CALL or OFF
is selected, the LCD flashes the message CALL or OFF during NORMAL DISPLAY mode. See Section IV Sensitivity
Setting for instructions on how to use the bargraph to determine t he proper sensitivity setting for the loop / lead-in netwo rk
connected to the channel. NOTE: Changing the sens itivity will reset the detector cha nnel. Care should be taken to ensure
that the detector channel is not reset while the detection zone is occupied.
PRESENCE / PULSE
Pressing either t he (UP) or (DOWN) pushbutton t oggles betwee n PRESENCE and PULSE modes. PRESENCE mode
outputs a call as long as the detection zone is occupied. CALL EXTENSION, C ALL DE LAY, and MAX PRE SENCE ca n all
modify the operation of the PRES ENCE mode. PULSE mode generates a 125 millisecond pulse when a vehicle is first
detected. On l y CA LL EXTENSION a nd CALL DELAY modify PULSE mode operation.
CALL DELAY TIME
Call Delay Time c an be adjusted from 0 to 255 se conds by press ing the (UP) or (DOWN) pushbutton. When the Call
Delay Time is 0, pressing the DOWN pushbutton step s t he value t o 255 s econds. Whe n the Ca ll De lay Ti me is 255 s econds,
pressing the UP pushbutton st eps the va lue t o 0. Dur ing the D EL AY P ERIO D, the c ha nne l’s LED flas he s at a four Hz rate
with a 5 0% duty cycle and the LC D shows a countdown of the Call D elay Ti me .
CALL EXTENSION TIME
Call Extension Time can be set from 0.0 to 25.5 sec onds b y press ing the (UP) or (DOWN) pushbutton. Whe n t he Call
Extension Time is 0.0, pressing the DOWN pushbutton steps the va lue to 25.5 second s. W hen the Call Exte nsio n Time is
25.5 seconds, pressing the UP pushbutton step s the value t o 0.0. Dur ing the EXT ENSION PER IOD, the channel’ s LED
flashes at a 16 Hz rate with a 50% duty cycle and the LCD shows a countdo wn of the Call Extension Time.
MAX PRESENCE TIME
Max Presence Time can be adjusted from OFF to 999 seconds by pressin g the (UP) or (DOWN) pushbutton. When the
time is set to OFF, pressing the DOWN pushbutton steps the value to 999 seconds. If Max Presence T ime is set to anyt hing
other than OFF, an EOG selection appears on the LCD after the Max Presence selection.
A call output occurs when either a vehicle is detected (Delay Time = 0) or after the delay timer has counted down to zero
following the arrival of a vehicle. The Max Presence timer starts timing when a call output occurs. Any time a call output
drops while the Max Presence timer is timing, the Max Presence timer is reset to the Max Presence time setting. The Max
Presence timer counts towards zero as long as the call output exists. If EOG (End of Green) control is OFF, the detector
channel resets at the time the Max Presence timer reaches zero. If EOG is ON, the detector channel goes into a wait state
when the Max Presence timer reaches zero. The channel remains in the wait state until either the call drops , or the green input
signal to the channel tra ns itions fr o m t he ON co nd it i o n to the OFF c o nditio n. I f t he call d r op s , no re s e t a c t io n o c c u rs . I f t he

the detector c hannel is reset with the vehicle over the loop. When the Max Presence timer is in the wait state, the MAX
PRESENCE - EOG message flashes on t he LCD. NOTE: If the Max Presence timer does reset the channel, no CALL
EXTENSION time will occur.
EOG (END OF GREEN) NOTE: Only appears if MAX PRESENCE TIME is not set to OFF.
Pressi ng e ithe r t he (UP) or (DOWN) pushbutton t oggles between ON and OFF. See MAX PRESENCE TIME above
for the effects of turning this feature on.
OPTION 1: LOOP INDUCTANCE
Pressi ng either the (UP) or (DOWN) pushbutton to ggles betw een ON and OFF. When O ption 1 is OFF the LC D
indicates three dashed lines (- - -) d uring the No Call state. When Opt ion 1 is ON th e LCD cont inuously ind icates the Loop
Induct ance val ue in microhenr ies while in the NORMAL DISPLAY mode. After 15 minutes, Option 1 turns OFF. The
display shows three digits if the inductance is between 15 and 999 μH. If the inductance is greater than 999 μH, the display
alternately flashes between 1 or 2 and the lower three digits. The four digits represe nt inductance values from 1000 to 2500
μH. When a vehicle is detected the Detect LED and bargraph display indicate the call. The count down of the Delay,
Extension, and Max Presence timers is not displayed when Option 1 is ON.
NOTE: Turning this option ON for any channel
turns it ON for all channels.
OPTION 2: INDUCTANCE CHANGE -∆L/L
Pressing either the (UP) or (DOWN) pushbutton toggles betwee n ON and OFF. When Option 2 is OFF, th e LCD
indicates a steady Call when a vehicle is detected. When Opt ion 2 is O N , the LCD indicates the -ΔL/L value w he n a ve hi c le is
detected. The maximu m -ΔL/L that occurred is displayed for two seconds unless a greater change occurs. NOTE: Turning this
option ON for any channel tur ns it ON fo r all channels.
OPTION 3: CALL EXTENSION TIME CONTROL
Pressi ng ei ther t he (UP) or (DOWN) pushbutton to ggle s be tween O N and OFF. When O ptio n 3 is OFF, the detector
channe l extends a ll calls for t he program med extensi on time. Whe n Option 3 is ON, the detector extends calls for the
programmed extens ion time only when t he associated Phase Gr een Inp ut (Delay Override) signal is active .
OPTION 4: NOISE FILTER DISABLE
Pressi ng e it he r t he (UP) or (DOWN) pushbutton to g gles be tw ee n ON and O FF. W hen O pt io n 4 is O FF, int er na l no is e
filtering is utilized. W he n Opt ion 4 is ON, internal noise filter ing is disabled thus providing a faster response time. Changing
the setting of this optio n will reset all detector cha nnels. It is recommended that this option only be turned ON when the
detector is used for speed and/or occupancy measurement applications. NOTE: Turning this option ON for any channel
turns it ON for all channels.
OPTION 5: PHASE GREEN LOOP COMPENSATION
Pressi ng e ithe r t he (UP) or (DOWN) pushbutton to ggles between ON a nd OFF. When Option 5 is OFF, normal loop
compe nsa t ion is use d. No co mpe ns at io n oc cur s d ur in g t he f irs t four minutes following the detection of a vehicle to preserve
small mo tor cyc le d etec ti on fo r a full four min utes . W hen O ptio n 5 is ON , loo p co mp ensa tio n be gins whe n the Pha se G ree n
(Dela y Overrid e) input becomes true and the cha nnel is outputting a Call. T he channe l will t hen begi n to tune o ut smal l
changes, such as adjacent lane pick up and/or loop drift. The presence time for average size vehicles is not affected (note that
a small motorcycle will a lso be tuned o ut in a short pe riod of t ime follow ing the start of Phase Green). This option is useful
in minimizing false detection resulting from adjacent lane pickup effect.
OPTION 9: THIRD CAR PASSAGE
Pressi ng ei ther t he (UP) o r (DOWN) pushbutton to ggles between ON and OFF. Option 9 is a paired channel option.
This means that it requires two detector channels to per form the function. C hannel 1 is paired w ith Channe l 2 a nd Cha nnel 3
is pair ed wi th Cha nnel 4 . When this option is c hanged for one of the paired channels, the state of the option for the other
paired channel is changed to match it. W hen O pt ion 9 is OFF the detector channel operates normally. When Option 9 is ON,
the output of the two paired channels are logically ANDed together. T his means that neither c hannel will output a Ca ll until
both channels have detection. T he first channel with detect ion will enter a pending state while waiting for detection in the
other paired channel. While in the pending state, the LCD will show Pnd. NOTE: Optio n 9 is mu tuall y exclus ive wit h
Option 10. Turning ON one option will automat ically t urn OFF the other option.
OPTION 10: DIRECTION AL LOGIC
Pressing either the (UP) or (DOWN) pushbutton toggles between ON a nd OFF. Optio n 10 is a paired c hannel opt ion.
This means that it requires two detector channels to per form the function. C hannel 1 is paired with C hanne l 2 and Cha nnel 3
is pair ed wi th Cha nnel 4 . When this option is changed for one of the paired cha nnels, t he state of the option for the other
paired channel is changed to match it. Whe n Option 10 is OFF, the detector channel operates normally. When Opt ion 10 is
ON, directional logic is enabled. Directional lo gic starts with a detection o n one channel. This channe l will go into the
pending state, display Pnd on the LCD, and NOT output a call. When both of the paired channels have a detection, the last
channel to have a detect ion will output a Call until t he detectio n for the last c hannel ends, e ven if the detect ion ends for the
first channel. NOTE: Option 9 is mutually exclusive with Option 10. Tur ning ON one opt ion will auto matically turn OFF
the ot her opt ion. N one o f the t iming funct ions o f the f irst c hanne l with a dete ctio n will t ime (D elay, Exte nsion, and M ax.
Presence) and the first channel will always operate in the Presence Mode regardless of programming f or the channel.
OPTION 11: AUDIBLE DETECT SIGNAL
Pressi ng e it he r t he (UP) or (DOWN) pushbutton to ggles between ON and OFF. W hen Option 11 is ON for a channel,
an aud ib le s ig nal is e mit ted an y t ime tha t c ha nne l’s de tection zone is occupied. This option can only be t urned ON for o ne
channel at a time. The last channel to have Opt ion 11 tur ned ON w ill be the only o ne wit h Option 11 t urned ON. De lay and
Extension time have no effec t on the audibl e signal. Option 11 will automatically turn off after 15 minutes.
OPTION 12: DETECTOR DISCONNECT
Pressi ng eithe r the (UP) or (DOWN) pushbutton toggles Option 12.0 between ON and OFF. When Option 12.0 is
turned ON, detector disconnect is enabled for that channel and Optio n 12.1 is now accessible. If Option 12.1 is OFF, the
extension timer also serves as the disconnect timer. If Option 12.1 is ON, the extension timer is inoperative and its
programmed value is used as the disconnect timer (gap timer). When Detector Disconnect is enabled (Option 12.0 is ON), the
detector operates normally during t imes when the phas e green input for the channel is OFF. Whe n the phase gree n inp ut is
ON, the detector will use t he value programmed as extension time to deter mine when to disconnect the output for that
channel. Therefore, if the detection zone is empty for the amount of time specified in the extension timer, the output for that
channel will be disconnected. If a call does not exist when the phase green input transitions to ON, the output is immediately
disconnected. The output is re-enabled when the phase gre en input transitions t o OFF.
OPTION 13: TRUE PRESENCE
TRUE PRESENCE can be set from 13.0 to 13.5 by press ing t he (UP) or (DOWN) pushbutton. When O ption 1 3 is OFF
(13.0), the detector operates in the normal PRESENCE mode. When this option is set to 13.1 through 13.5, TRUE
PRESENCE is O N. Whe n Option 13 is O N, TRUE PRESENCE will hold the Call for as long as the vehicle is prese nt and
power is not removed or the detector reset. TRUE PRESENCE time applies only for normal size automobiles and trucks and
for normal size loops (approximately 12 f t

OPTION 14: SENSITIVITY BOOST
SENSITIVITY BOOST ca n be set from 14. 0 to 14.4 by pressing the (UP) or (DOWN) pushbutton. Whe n Op t i o n 1 4 is
set to 14.0, SENSITIVITY BOOST is turned O FF. When this option is set to 14.1 thro ugh 14.4, SENSITIVITY BOO ST is
ON. SENSITIVITY BOOST increases the sensitivity of the detector once it has detected an object. When setting this option,
the digit to the right o f the decimal point indicates the number o f sensitivity levels t hat the sensitivity will increase after a
detection has occurred.

LOOP FAIL
The number of loop failures logged in the loop fail register is displayed. Any time a channel enters the Fail Safe Mode due to
a recognized loop failure, the loop fail register is incremented by o ne count. Pressing either the
(UP) or (DOWN)
pushbutton will clea r the loop fail register. The nu mber of loop fail counts is also reset to ze ro by any power down, when the
harness is disconnected from the detector, or when the channel is reset. The loop fail register is not reset when the setting of
Option 4 (Noise Filter Disable) is changed or when the channel’ s sens itivity or frequency is changed.
