5.5.4.7 Detector Alignment – Second Lane Detection (default)
The detector default setup uses a static detection algorithm. The detector is aimed
perpendicular to the traffic flow and just below the centre of the carriageway, as shown in
Figure 18 below. To use this installation method, ensure DIP switch 6 is set to ‘0’, or
using the appropriate terminal command ‘DAA’ is set to ‘0’
1
. This is factory default.

5.5.4.8 Maximum Presence Time
The maximum presence time attribute defines the period of continuous detection before
the detector tunes the stationary object and detection returns to normal. The default
setting is for a period of 4 minutes. However if adjustment is required, DIP switch 5 can
set the maximum presence time to 30 minutes. Alternatively, if a user defined value is
required, the terminal command MPT can be set to the user defined variable (reference
section 7.7.4).
5.5.4.9 Detector Fault Monitor (DFM)
The detector has a fault monitor function. In the default mode, the detector will generate a
fault output (equivalent to a permanent detect) if the detector has not registered an
activation for a period of twenty hours.
This duration can be adjusted to a user defined value by setting DIP Switch 7 to ‘1’ (On)
and then using the terminal command DFM (reference section 7.7.4).
