3.2.5 CHANNEL ID
A five characters ID name can be set to any alphanumeric character A through Z, 0 through
9 or space to custom label each channel of detection. Using the “MENU (Back/Select)”
switch, pressing “Select” causes the cursor to move to the next digit to the right and
pressing “Back” causes the cursor to move to the next digit to the left. To edit each digit,
use the “SCROLL (Up/Down)” switch and press DOWN or UP keys accordingly. Continue
until all of the digits are set and then press the “MENU (Back/Select)” switch down until the
screen highlights OK to confirm and save.
3.3 VEHICLE COUNTING (ORACLE EC SERIES)
Each channel Count Mode may be set to YES or NO. If YES is selected then the “SET UP
Counting Type” and “Enable Count Output” can be set.
3.3.1 COUNTING TYPE (
ACCURATECOUNT
)
The “Counting type” can be selected to be either on one loop or up to eight loops
connected in series. The “one loop” setting includes all loop configurations, square or
rectangle, where a single loop is connected to the loop inputs. The “Loop Length” setting
should be selected to optimize counting accuracy. A “Short” length is typically considered
as a 6’ long loop. The “Long” length is typically considered as a loop 10’ or greater in
length.
On the two to eight loop setting the Count must be derived from a configuration of individual
loops (6’ x 6’ square or round loops on 12’ to 15’ centers) connected in series within a
single lane. Each vehicle that enters the detection zone will be counted irrespective of
whether vehicles are already present. Accuracy is dependent on the type and volume of
traffic and loop configurations, high long term accuracies are possible.
3.3.2 VEHICLE COUNTING OUTPUT (
ACCURATECOUNT
)
For the ORACLE 2EC, 4EC models only, the Vehicle Counting output may be set to NO or
YES. If Count Outputs are set to NO then the secondary outputs on the edge card
connector are disabled, Count information will then only be available on the front panel
LCD. If YES is selected, then a secondary output will be produced in addition to the primary
CALL output for every vehicle entering the loop zone. Each vehicle entering the loop will
cause an output pulse of 125ms ± 25ms from the respective secondary “Count” output on
pin S (Channel 1) and pin Y (Channel 2). These pins are typically assigned to Channel 3
and 4 in the rack.
3.4 DISPLAY MODES
Each channel display (view) can be set to either Frequency (Freq), Inductance (Induct), or
Count (2EC, 4EC). This sets the screen that is displayed when the detector starts up or
when RUN is selected.
The Frequency (Freq) view displays the channel ID, sensitivity level, and loop frequency
when there is no vehicle in the loop zone. When a vehicle enters the loop zone, the
channel ID, count down timer (Presence mode only), loop frequency, DEFLECTOMETER
®
Pie Graph, Numeric Indicator, and Streaming Graph are displayed and active.
The Inductance (Induct) view displays the channel ID, sensitivity level, and loop inductance
when there is no vehicle in the loop zone. When a vehicle enters the loop zone, the
channel ID, count down timer (Presence mode only),
∆
L/L% value, DEFLECTOMETER
®
Pie Graph, Numeric Indicator, and Streaming Graph are displayed and active.
The Count view (2EC, 4EC) displays the channel ID and current count accumulated since
the channel was last reset along with the loop frequency. To reset the count accumulator
use the SCROLL (Up) switch.
