Dynamic Teach-In of 1 setpoint. For SP1 only
Principle
Dynamic teach-in allows you to set the switching point
without interrupting the process.
Typical application: Sensitivity setup to a process running
perpendicular to the light beam of the sensor
During the teach procedure, which begins with the Start
command and ends with the Stop command, the sensor
carries out measurements and determines the minimum
and maximum of the obtained values. The Teach Apply
command determines the switching point SP1.
