C3._ Frequency Output X
C3._
Frequency Output X
X stands for one of the connection terminals A, B, or D_ stands for Fct. C3.2 (A) /
C3.3 (B) / C3.5 (D)
C3._.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. C3._.3 100% pulse rate)
C3._.2
Pulse Width
Only available if set to “Fixed” in Fct. C3._.1.
Range: 0.05 to 2000 ms
Note: max. setting value Tp [ms]
≤
500 / max. pulse rate [1/s], gives the pulse width =
time where the output is activated
C3._.3
100% Pulse Rate
Pulse rate for 100% of the measuring range
Range: 1 to 10000 Hz
Limitation 100% pulse rate
≤
100/s: I
max
≤
100 mA
Limitation 100% pulse rate > 100/s: I
max
≤
20 mA
C3._.4
Measurement
Measurements for activating the output
Select:
Volume Flow / Mass Flow / Temperature / Density / Velocity / Sensor
Average / Sensor Deviation / Drive Level / Tube Frequency / Strain 1 / Strain 2 / 2
Phase Signal
Depending on the settings for the concentration measurement, the following
measurements are possible:
Concentration 1 / Concentration 2 / Conc. mass flow 1 / Conc. mass flow 2 /
Conc. volume flow 1 / Conc. volume flow 2
C3._.5
Range
0 to 100% of the measurement set in Fct. C3._.4
x.xx - xx.xx _ _ _ (format and unit depend on the “measurement”, see above)
C3._.6
Polarity
Set polarity; the flow direction in C1.3.2 must be noted!
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)
C3._.7
Limitation
Limitation before applying the time constant
±xxx - ±xxx%; range: -150 to +150%
C3._.8
Low Flow Cutoff
Sets the measurement to “0” for low values
x.xxx±x.xxx%; range: 0.0 to 20%
(1st value = switching point / 2nd value = hysteresis), condition: 2nd value
≤
1st value
C3._.9
Time Constant
Range: 000.1 to 100 s
C3._.10
Invert Signal
Select:
Off (activated output: switch closed)
On (activated output: switch open)
C3._.11
Phase Shift w.r.t. B
Only available when configuring the terminal A or D 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)
