C2.3.11

special functions

This function is only available at the terminal B frequency output. At the

same time, 2 frequency outputs must be available:

1st output at terminal A or D / 2nd output at terminal B

The B output is operated as a slave output, controlled and set using master

output A or D

Selection: off (no phase shift) / phase shift w.r.t. D or A (slave output is B and

master output is D or A)

C2.….12

information

Serial no. of the I/O board, software version no. 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 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

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 (not

not

not

not valid for PF (partly filled))

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 C2.….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"

(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)
