C2._.2 Status Output Y Only appears if output A...D is set under "Mode" (see above), and this output
is a "Status Output".
Same Signal (like other connected status output, signal can be inverted, see
below)
C2._.2 Limit Switch Y and Control
Input Y
Only appears if output A...D / input A or B is set under "Mode" (see above),
and this output / input is a "Limit Switch / Control Input".
Status Off (is always selected here if Status Output X is connected with a
Limit Switch / Control Input Y).
C2._.2 Output Y Only appears if output A...D is set under "Mode" (see above) and this output
is switched off.
C2._.3 Invert Signal Select:
Off (activated output: switch closed) /
On (activated output: switch open)
C2._.4 Information Serial no. of the I/O board, software version no. and production date of the
circuit board
C2._.5 Simulation Sequence see B1._ Status Output X
C2._ Limit Switch X
C2._ Limit Switch X X stands for one of the connection terminals A, B, C or D
C2._.1 Measurement Select:
Volume Flow / Mass Flow / Flow Speed / Velocity of Sound / Gain / SNR /
Diagnostics 1 / Diagnostics 2
C2._.2 Threshold Switching level, set threshold with hysteresis
xxx.x ±x.xxx (format and unit depend on the measurement, see above)
(1st value = threshold / 2nd value = hysteresis),
condition: 2nd value ≤ 1st value
C2._.3 Polarity Set polarity, please note Flow Direction
Select:
Both Polarities (plus and minus values are displayed) /
Positive Polarity (display for negative values = 0) /
Negative Polarity (display for positive values = 0) /
Absolute Value (always displays positive, with both negative and positive
values)
C2._.4 Time Constant Range: 000.1…100 s
C2._.5 Invert Signal Select:
Off (activated output: switch closed) /
On (activated output: switch open)
C2._.6 Information Serial no. of the I/O board, software version no. and production date of the
circuit board
C2._.7 Simulation Sequence see B1._ Limit Switch X
