6.3 Pot 1 and Pot 2 – Detection area
There are two potentiometers for the adjustment of the detection area referred to as Pot 1 and Pot 2.
Pot 1 is used to adjust the detection area length ( Figure 5). Pot 2 is then used to adjust the detection area
width in relation to the detection area length.
Pot 1: Detection area length
Pot 1 is located directly to the right of
the DIP switches. It sets the detection
area length (l) between 1 m (40 in)
and 3 m (120 in).
Important: The detection area length
must be set about 0.2 m (8 in) above
floor level as the floor would otherwise
interfere with the sensor detection
ability.
Adjust Pot 1 according to
Table 3 / Table 4.
Pot 2: Detection area width
Pot 2 sets the detection area width (w)
in relation to the detection area length.
The width can be adjusted between
0.3 and 0.7 x the detection area length.
Adjust Pot 2 according to
Table 5 / Table 6.
Example (row/column highlighted
in gray): The detection area length (l)
has already been set to 2.5 m (100 in).
The detection area width (w) should
now be set to 1.5 m (59 in). In order to
do this, take the following steps:
1. Look up the corresponding
detection area length row in
Table 6 (i.e. 2.5 m / 100 in).
2. Move along this row to the desired
detection area width (i.e. 1.5 m /
59 in).
3. Directly below this figure you will
find the required Pot 2 setting, in
this example the value is 3.
4. Set Pot 2 using a small
screwdriver
