CALL DELAY TIME
Call Delay Time can be adjusted from 0 to 255 seconds by pressing the
(UP) or
(DOWN) pushbutton. When the
Call Delay Time is 0, pressing the DOWN pushbutton steps the value to 255 seconds. When the Call Delay Time is 255
seconds, pressing the UP pushbutton steps the value to 0. During the DELAY PERIOD, the channel’s LED flashes at a
four Hz rate with a 50% duty cycle and the LCD shows a countdown of the Call Delay Time.
CALL EXTENSION TIME
Call Extension Time can be set from 0.0 to 25.5 seconds by pressing the
(UP) or
(DOWN) pushbutton. When the
Call Extension Time is 0.0, pressing the DOWN pushbutton steps the value to 25.5 seconds. When the Call Extension
Time is 25.5 seconds, pressing the UP pushbutton steps the value to 0.0. During the EXTENSION PERIOD, the channel’s
LED flashes at a 16 Hz rate with a 50% duty cycle and the LCD shows a countdown of the Call Extension Time.
MAX PRESENCE TIME
Max Presence Time can be adjusted from OFF to 999 seconds by pressing 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 Time is set to
anything 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 transitions from the ON condition to the OFF condition. If the call drops, no reset action
occurs. If the Max Presence timer is in the wait state when the green input signal transitions from the ON condition to the
OFF condition, the detector channel 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 the 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.
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. See MAX PRESENCE TIME
above for the effects of turning this feature on.
OPTION 1: LOOP INDUCTANCE
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 1 is OFF, the LCD
indicates three dashed lines (
- - -
) during the No Call state. When Option 1 is ON, the LCD continuously indicates the
Loop Inductance value in microhenries 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
μ
H. If the inductance is greater than 999
μ
H, the
display alternately flashes between
1
or
2
and the lower three digits. The four digits represent inductance values from
1000 to 2500
μ
H. When a vehicle is detected the Detect LED and bargraph display indicate the call. The countdown of
the Delay, Extension, and Max Presence timers is
not
displayed when Option 1 is ON.
NOTE:
Turning this option ON
for either channel turns it ON for both channels.
OPTION 2: INDUCTANCE CHANGE -
∆
∆
∆
∆
L/L
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 2 is OFF, the LCD
indicates a steady Call when a vehicle is detected. When Option 2 is ON, the LCD indicates the -
Δ
L
/
L value when a
vehicle is detected. The maximum -
Δ
L
/
L that occurred is displayed for two seconds unless a greater change occurs.
NOTE:
Turning this option ON for either channel turns it ON for both channels.
OPTION 3: CALL EXTENSION TIME CONTROL
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 3 is OFF, the detector
channel extends all calls for the programmed extension time. When Option 3 is ON, the detector extends calls for the
programmed extension time
only
when the associated Phase Green Input (Delay Override) signal is active.
OPTION 4: NOISE FILTER DISABLE
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 4 is OFF, internal
noise filtering is utilized. When Option 4 is ON, internal noise filtering is disabled thus providing a faster response time.
Changing the setting of this option will reset both detector channels.
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
either channel turns it ON for both channels.
OPTION 5: PHASE GREEN LOOP COMPENSATION
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 5 is OFF, normal loop
compensation is used. No compensation occurs during the first four minutes following the detection of a vehicle to
preserve small motorcycle detection for a full four minutes. When Option 5 is ON, loop compensation begins when the
Phase Green (Delay Override) input becomes true and the channel is outputting a Call. The channel will then begin to tune
out small 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 also be tuned out in a short period of time following the start of Phase Green).
This option is useful in minimizing false detection resulting from adjacent lane pickup effect.
OPTION 6: DISPLAY / RESET VEHICLE COUNT
This option has two parameters. Option 6.0 is used to turn the display of vehicle counts ON and OFF. Option 6.1 is used
to reset the vehicle count to zero. Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF
for
either parameter. When Option 6.0 is ON, the NORMAL DISPLAY will show the accumulated vehicle count since last
vehicle count reset. The display will show the hundreds, tens, and ones digits until the accumulated count exceeds 999. At
this point the display will alternate between the ten thousands and thousands digits and the remaining three digits for
hundreds, tens, and ones. Setting Option 6.1 to ON resets the accumulated vehicle count. The setting automatically
returns to the OFF state when the parameter is exited.
OPTION 7: LOOP CONFIGURATION FOR COUNTING
Pressing either the
(UP) or
(DOWN) pushbutton scrolls through the available loop configurations for counting. The
currently available options are 7.01 through 7.05 where the last two digits specify how many loops there are in the
detection zone. The detection zone must be confined to a single lane of traffic.
OPTION 9: THIRD CAR PASSAGE
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. Option 9 is a paired channel option.
This means that it requires two detector channels to perform the function. Channel 1 is paired with Channel 2. When this
option is changed for one of the paired channels, the state of the option for the other paired channel is changed to match it.
When Option 9 is OFF, the detector channel operates normally. When Option 9 is ON, the output of the two paired
channels are logically ANDed together. This means that neither channel will output a Call until both channels have
detection. The first channel with detection 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:
Option 9 is mutually exclusive with Option 10.
Turning ON one option will automatically turn OFF the other option.
OPTION 10: DIRECTIONAL LOGIC
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. Option 10 is a paired channel
option. This means that it requires two detector channels to perform the function. Channel 1 is paired with Channel 2.
When this option is changed for one of the paired channels, the state of the option for the other paired channel is changed
to match it. When Option 10 is OFF, the detector channel operates normally. When Option 10 is ON, directional logic is
enabled. Directional logic starts with a detection on one channel. This channel 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
detection will output a Call until the detection for the last channel ends, even if the detection ends for the first channel.
NOTE:
Option 9 is mutually exclusive with Option 10. Turning ON one option will automatically turn OFF the other
option. None of the timing functions of the first channel with a detection will time (Delay, Extension, and Max. Presence)
and the first channel will always operate in the Presence Mode regardless of programming for the channel.
OPTION 11: AUDIBLE DETECT SIGNAL
Pressing either the
(UP) or
(DOWN) pushbutton toggles between ON and OFF. When Option 11 is ON for a
channel, an audible signal is emitted any time that channel’s detection zone is occupied. This option can only be turned
ON for one channel at a time. The last channel to have Option 11 turned ON will be the only one with Option 11 turned
ON. Delay and Extension time have no effect on the audible signal. Option 11 will automatically turn off after 15
minutes.
OPTION 12: DETECTOR DISCONNECT
Pressing either 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 Option 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 times when the phase green input for the channel is OFF. When the phase green
input is ON, the detector will use the value programmed as extension time to determine 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 green input transitions to OFF.
DETECTOR ID
This feature is used to assign a unique identification value to the detector for communication purposes. Detector ID
settings can range from 000 to 253. Pressing either the
(UP) or
(DOWN) pushbutton will increment or decrement
the ID setting by one digit. NOTE: When first initialized, the detector ID setting is 000.
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 one count. Pressing either the
(UP) or
(DOWN)
pushbutton will clear the loop fail register. The number of loop fail counts is also reset to zero 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 sensitivity or frequency is changed.
After each detector channel is initialized and operating in a normal manner, the channel is continuously monitored for
faulty loop conditions (e.g. broken wires, poor splices, bad solder connections, etc.). If the measured loop inductance
value rapidly changes by more than ±25%, the channel is considered to have failed. The channel then enters the Fail Safe
Mode, which generates a constant Call Output. When a channel is in Fail Safe Mode, the Loop Fail symbol located at the
