5.5.4.3 Detector Angle

The initial installation angle will change depending on the installation height. As a guide

these are listed as:

4m – 50 degrees from horizontal

6m – 75 degrees from horizontal

8m – 85 degrees from horizontal

Reference section 4.7.1 for instructions on how to pre-set mounting angle

5.5.4.4 Detector Angle for Second Lane Detection

The initial installation angle will change depending on the installation height. In order to

maintain a reasonable line-of-sight it is expected that second lane detection will require at

least 6m installation height as a minimum. As a guide these are listed as:

6m – 50 degrees from horizontal

8m – 75 degrees from horizontal

Reference section 4.7.1 for instructions on how to pre-set mounting angle

5.5.4.5 Detector Alignment - 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’

. This is factory default.

For optimum performance, it is recommended that this alignment is used.
