Adjustment of valve position indication / Teach-in
The continuously measuring valve position measuring system is
tought via a reference valve movement.
The respective positions for the closed and open valve position as
well as for further valve positions, e.g. seat lifting, are travelled to
and the corresponding position of the sensor system is permanently
stored in the memory of the electronic module. This process is
called Teach-In.
The Teach-In is started by pressing the Teach-In key at the
electronic module. The key must be pressed permanently for 3
seconds.
After the start of the Teach-In the LED 9 lights up and the valve
travels into the corresponding final positions and back into the basic
position. The positions of the corresponding valve positions are
stored.
