C2. .6 polarity Set polarity, please note flow direction in C1.2.2!
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. .7 limitation Limitation before applying the time constant.
± xxx … ±xxx%; range: -150…+150%
C2. .8 low flow cutoff Sets output value to "0":
x.xxx ± x.xxx%; range: 0.0…20%
(1st value = switching point / 2nd value = hysteresis),
condition: 2nd value ≤ 1st value
C2. .9 time constant Range: 000.1…100 s
C2. .10 invert signal Select:
off (activated output generates a high current at the output, switch closed) /
on (activated output generates a low current at the output, switch open)
C2. .12 information Serial number of the I/O circuit board, software version number and
production date of the circuit board
C2. .13 simulation Sequence see B1. frequency out X
C2. pulse output X
C2. pulse output X X stands for connection terminals D
stands for Fct. no. C2.5 (D)
C2. .1 pulse shape Specify the pulse shape.
Select: symmetric (about 50% on and 50% off) / automatic (constant pulse
with about 50% on and 50% off at 100% pulse rate) / fixed (fixed pulse rate,
setting see below Fct. C2. .3 100% pulse rate)
C2. .2 pulse width Only available if set to "fixed" in Fct. C2. .1
Range: 0.05…2000 ms
Note: max. setting value Tp [ms] ≤ 500 / max. pulse rate [1/s], gives the pulse
width = time where the output is activated
C2. .3 max. pulse rate Pulse rate for 100% of the measuring range.
Range: 0.0…10000 1/s
Limitation 100% pulse rate ≤ 100/s: I
max
≤ 100 mA
Limitation 100% pulse rate > 100/s: I
max
≤ 20 mA
C2. .4 measurement Measurements for activating the output.
Select: volume flow / mass flow
C2. .5 pulse value unit Selection of the unit from a list, depending on the measurement.
C2. .6 value p. pulse Set value for volume or mass per pulse.
xxx.xxx, range in [l] or [kg] (volume or mass for current output C2. .6)
At max. pulse rate see above 2. .3 pulse output.
C2. .7 polarity Set polarity, please note flow direction in C1.2.2!
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. .8 low flow cutoff Sets output value to "0"
x.xxx ± x.xxx%; range: 0.0…20%
(1st value = switching point / 2nd value = hysteresis),
condition: 2nd value ≤ 1st value
C2. .9 time constant Range: 000.1…100 s
No. Function Settings / descriptions
