(Red) LED will return to normal operation. The FAULT (Yellow) LED will continue to flash
with the sequence signifying the type of fault that was last detected. In the case of the
excessive inductance change fault (possible loss of a loop within a series of loops), the unit
will log the fault and retune to the new inductance after a period of two seconds. The
logged fault will be stored in the Event Log memory.
2.3 VEHICLE COUNTING (ORACLE EC SERIES)
2.3.1 VEHICLE COUNTING (
ACCURATECOUNT
) DISPLAY
If
AccurateCount
(Enable Vehicle Counting) mode is enabled, the LCD will reflect actual
counts from the secondary “Count” outputs. For each channel, when a vehicle occupies the
loop zone, the LCD counter accumulates one vehicle count per output. The counter is
capable of accumulating 999,999 vehicle counts per channel before rolling over to zero.
2.3.2 VEHICLE COUNTING (
ACCURATECOUNT
) MODE
For each channel of the Oracle 2EC model only, the
AccurateCount
(Enable Vehicle
Counting) output feature can be enabled via the “SET UP” menu to produce a secondary
output 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 secondary
“Count” output on pin S (Channel 1) and pin Y (Channel 2), irrespective of the size of the
loop. See section 3.3.2.
When the Secondary outputs are enabled for counting, the Secondary Status outputs on
pin 16 (Channel 1) and pin 22 (Channel 2) will be set to the True state (TS2 state #1).
2.3.3 VEHICLE COUNTING (
ACCURATECOUNT
) LOOP CONFIGURATIONS
For each channel, when the
AccurateCount
(Enable Vehicle Counting) feature is enabled, a
loop configuration must be selected, via the “Set up Counting Type” menu for either a
single loop or up to eight loops connected together in series. For the single loop case, a
Short or Long configuration is also provided. See section 3.3.
