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 off Only appears if output A...D is set under "mode" (see above) and this
output is switched off.
C2. .3 invert signal Off (activated output supplies a high current, switch closed)
On (activated output supplies a low current, switch open)
C2. .4 information
1 st line: serial number of the I/O circuit board
2 nd line: software version number
3 rd line: production date of the circuit board
C2. .5 simulation Sequence see B1. status output X
limit switch X
C2. limit switch X X stands for one of the connection terminals A, B, C or D.
stands for A, B, C or D.
C2. .1 measurement Measurements for activating the output.
Select: volume flow / corr. volume flow / mass flow / molar mass /
flow speed / velocity of sound / gain / diagnostics 1, 2, 3
C2. .2 threshold Switching level, set threshold with hysteresis.
xxx.x ±x.xxx (format and unit depend on the measurement, see above)

C2. .3 polarity Set measured value polarity, please note flow direction in C1.3.2!
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 (use for the output)
C2. .4 time constant Averages measurement
Increasing value improves stability but delays the reaction.
Range: 000.1…100 s
C2. .5 invert signal Define limit switch activation
Off (activated output generates a high current, switch closed)
On (activated output generates a low current, switch open)
C2. .6 information
1 st line: serial number of the I/O circuit board
2 nd line: software version number
3 rd line: production date of the circuit board
C2. .7 simulation Sequence see B1. limit switch X
control input X
C2. control input X X stands for connection terminal A or B.
stands for A or B.
