8�3�4�1 Example: Calibrate switch output
For example, the Solimotion FTR20 with switch output should be calibrated such that the
output relay remains closed despite the fluctuating signal strength (if loading of the belt is low
(= minimum signal strength), the switch point (LED 5) must remain reliably exceeded). If the
belt is empty, the switch point must not be exceeded.

c
Signal strength when belt is empty
d
Signal strength when belt loading is minimum
e
Signal strength when belt loading is maximum
The calibration is carried out as follows:
Increasing the gain (
function B
) by 2 LEDs to 7 (shifting the detection range in the
direction of smaller signal strengths)
→ Display of the maximum belt loading (dashed curve) now with 10 LEDs
→ The minimum loading is displayed with 6 to 7 LEDs
→ The empty belt is displayed with 4 to 5 LEDs
Reduction of the detection range (
function C
) by 1 LED to 3 in order to reduce the signal
strength display of the measured signal strength of the empty belt
→ Display of the empty belt (bold curve) with 3 LEDs
→ The minimum loading is displayed with 5 to 6 LEDs
→ Exceeding of the switch point with low loading is ensured
