9. To output the transducer values (P1,P2,P3) separately and the
average value (P). Indicates errors if the maximum pressure
difference between the transducers is exceeding the defined value.
The two-or three-digit error field in the end of the line is expressing
the error state of the transducers. Number 1 means error and number 0
normal state. The first digit shows state of transducer 1 (P1), second
digit shows state of transducer 2 (P2) and the third digit shows
transducer 3 (P3).
