C2.2.7 time constant Range: 000.1…100 s
C2.2.8 information Serial no. of the I/O board, software version no. and production date of the
circuit board
C2.2.9 simulation Sequence see B1.2 current output A
C2.2.10 4mA trimming Trimming of the current at 4 mA
Reset to 4 mA restores the factory calibration.
Used for HART
®
setting.
C2.2.11 20mA trimming Trimming of the current at 20 mA
Reset to 20 mA restores the factory calibration.
Used for HART
®
setting.
C2.3 frequency out X
C2.3.1 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. C2.3.3 100% pulse rate)
C2.3.2 pulse width Only available if set to "fixed" in Fct. C2.3.1
Range: 0.05…500 ms
Note: max. setting value Tp [ms] ≤ 500 / max. pulse rate [1/s], gives the pulse
width = time where the output is activated
C2.3.3 100 % pulse rate Pulse rate for 100% of the measuring range
Range: 1…10000 Hz
Limitation 100% pulse rate ≤ 100/s: I
max
≤ 100 mA
Limitation 100% pulse rate > 100/s: I
max
≤ 20 mA
C2.3.4 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 (always displays positive, with both negative and positive
values)
C2.3.5 low flow cutoff Sets the measurement to "0" for low values
x.xxx ± x.xxx%; range: 0.0…20%
(1st value = switching point / 2nd value = hysteresis),
condition: 2nd value ≤ 1st value
C2.3.6 time constant Range: 000.1…100 s
C2.3.7 invert signal Select:
off (activated output: switch closed) /
on (activated output: switch open)
C2.3.8 information Serial no. of the I/O board, software version no. and production date of the
circuit board
