Documentation of the topography The topography describes the layout of the complete system. Starting from the blower, all diverters and stations must be indicated. Hereby the diverter position and the station type must be considered. For each station the complete way must be described. System drawing Draw a sketch (or a drawing) showing all the units. The resting position of the diverter (0 position) is called the main tube. Indicate the 0 position and the output numbers of the diverters (0, 1 and for 3-way-diverter also 2). Attention! The middle position (1) of a 3-way-diverter must not be the 0 position. For the main tube run, you can also use an active position. However, this will be a disadvantage because this diverter will always be moved in an active position when a sending- or receiving- procedure runs behind it. (Alteration of the resting position, exchange the motor connections and reed contacts, middle position must be readjusted). Numbering the stations:
