C2. .15 4mA trimming Trimming of the current at 4 mA
Reset to 4 mA restores the factory calibration.
Used for HART ® setting.
C2. .16 20mA trimming Trimming of the current at 20 mA
Reset to 20 mA restores the factory calibration.
Used for HART ® setting.
C2. frequency out X
C2. frequency out X X stands for one of the connection terminals A, B or D
stands for Fct. no. C2.2 (A) / C2.3 (B) / 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. .3 100% 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 (not not not not valid for PF (partly filled)) / diagnosis
value / flow speed / coil temperature / conductivity (not not not not valid for PF (partly
filled)) and CAP (capacitive)) / level (only only only only valid for PF (partly filled))
C2. .5 range 0…100% of the measurement set in Fct. C2. .4
0…xx.xx _ _ _ (format and unit depend on the measurement, see above)
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. .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. 2.5.6 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)
