1)
In case of default valid range:
Physical full scale value of the sensor (10 Volt)
equa
ls to 1’000’000.
(In case of 2 sensor operation the full scale of
high range sensor equals to 1’000’000.)

1)
min signal value = “valve is closed”
max signal value = “valve is opened”
The position 9’999’999 (or 9’999’999.0 for
floating point) show an unknown valve position
– e.g. during synchronization at startup
If Isolation valve failure is active:
The position = ((max signal value - min signal
value) * 0.2) + min signal value.
e.g.: max signal value = 100’000
min signal value = 0
Position = ((100’000 – 0) * 0.2) + 0 = 20’000
