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

C2.3.9

Sequence see B1.3 frequency out D

No.
