Operation Modes

Press and hold the push-button to cycle through the different operation modes; release the

button when the desired mode is reached. A quick press and release of the push-button will

exit out of any mode and return the unit back to normal operation.

Table 6.2 describes the different operating modes. To use dual-loop emulation, you must

wire both the primary and secondary outputs; to use single-loop emulation, you must only

wire the primary output.

Definition

PR (Presence)

Red

Outputs contact closures for single-loop or dual-loop
emulation. Dual-loop emulation will signal the radar’s
speed and duration measurements. Speed is signaled
as the elapsed time between the primary and second-
ary outputs. Duration in the radar beam is signaled as
the duration of the outputs. Single-loop emulation
will simply signal the radar’s duration measurement
(no speed information).

PU (Pulse)

Orange

Outputs contact closures for single-loop or dual-loop
emulation. Dual-loop emulation will signal the radar’s
speed measurement using the time elapsed between
the onset of the primary and secondary outputs, but
not the radar’s duration measurement. Instead the
outputs will be held active for precisely 125 millisec-
onds for every vehicle detected. This fixed period
of time is necessary when integrating with some
systems and is often used in counting applications.
Single-loop emulation will simply signal that the radar
detected a vehicle (no duration or speed information).

AC (Actuation)

Green

Outputs contact closures for single-loop emulation.
This mode of single-loop emulation is used both with
true presence and continuous passage detectors.
True presence detectors signal the existence of a
stopped or moving vehicle within the detector beam.
Continuous passage detectors signal the existence
of a moving vehicle meeting specific criteria (speed,
range, ETA) within the detector beam. When a vehicle
within the detector beam meets the requirements of
the true presence or continuous passage detector, the
associated rack card output will be closed. This is the
only mode used by SmartSensor Advance. With side-
fire radar sensors this mode is used for occupancy
data collection.
