7.12.6.1 Object 0x2330: Active transducer interface system
This parameter keeps the number of the transducer interface for the actual system pressure value. Instead of
using a pressure sensor it is also possible to use a constant value.
7.12.6.2 Object 0x5217: Active transducer interface tank
This parameter keeps the number of the transducer interface for the actual tank pressure value. Instead of us-
ing a pressure sensor, it is also possible to use a constant value.
7.12.7 Alpha correction
The alpha correction can be used to compensate the area differences between A-side and B-side of a differ-
ential cylinder.

7.12.7.1 Object 0x5219: Flow alpha
This parameter is the multiplier for the pressure in B-side to get the alpha corrected actual pressure.
