3. INSTALLATION AND OPERATION
3.2.4 Supporting Structure
The Transmitter and Receiver units should be fixed to a stable supporting structure using the
mounting plates supplied.
Note: The maximum movement of the supporting structure under all anticipated operating
conditions must be ±0.5
If either unit is to be free standing and not mounted to existing supports or structures, and the height
above the ground is no more than 3m, the supporting structure shown is recommended:

500mm
minimum
Note: The pipe can be filled with concrete to provide extra robustness if necessary.
3.2.5 Orientation
Searchline Excel is solar immune and therefore there is no need to take account of the sun's
movement when considering orientation.
When positioning the units do not install them with the optical axis at an angle greater than 45
to the horizontal. This is to avoid dirt/water buildup on the windows.
