C2. .11 phase shift w.r.t. B
Only available when configuring the A or D terminal and only if output
B is a pulse or frequency output. If setting in Fct. C2.5.6 is "both
polarities", the phase shift is prefixed by a symbol, e.g. -90° and +90°.
Select: off (no phase shift) /
0° phase shift (between outputs A or D and B, inversion possible) /
90° phase shift (between outputs A or D and B, inversion possible) /
180° phase shift (between outputs A or D and B, inversion possible)

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
Set time for pulse activation.
Only available if Fct. C2. .1 is set to "Fixed".
Range: 0.05…2000 ms
Note: max. setting value T
p
[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 Hz
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 / corr. volume flow
C2. .5
value p. pulse
Set value for volume or mass per pulse.
xxx.xxx (format and unit depend on the measured variable)
At max. pulse rate see above C2. .3 pulse output.
C2. .6
polarity
Set 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. .7
low flow cutoff
Below set value, pulse output is set to zero.
