The electronics inside the VTS-Box digitizes the measured cursor voltage of the potentiometer. This digital information is first processed and then transferred back into an analogue output signal, e.g. 0 to 10 V. As a result of the digitalization the measurement range can be teached and a switching point can be set. By teaching the sensor, the measurement range is reduced which leads to an improved resolution. One, or two teach limits may be set, with a reduction of the measurement range of up to 50% of the original full scale. The reduced, teached measurement range can be placed anywhere within the original full scale. The switching point can be placed anywhere within the measurement range and is independent of a teaching of the measurement range. Therefore, the switching point can also lie outside of a teached range.
Another advantage of a sensor that can be teached is the possibility to use it in different applications, because the measurement range can be adapted accordingly. There is no need to buy a new sensor every time a different range is required. The configuration of a position sensor is easily done by using the LED button, that is integrated in the VTS-Box. The light signal of the LED indicates the menu point, that is active at the moment and gives feedback to the user, if for example the teaching process was successful.
