C2.… current out X

C2.…

current out X

X stands for one of the connection terminals A, B or C

…

stands for Fct. no. C2.2 (A) / C2.3 (B) / C2.4 (C)

C2.….1

range 0%…100%

Current range for the selected measurement, e.g. 4...20 mA,

corresponds to 0…100%

xx.x … xx.x mA; range: 0.00…20 mA

(condition: 0 mA ≤ 1st value ≤ 2nd value ≤ 20 mA)

C2.….2

extended range

Defines the min. and max. limits.

xx.x … xx.x mA; range: 03.5…21.5 mA

(condition: 0 mA ≤ 1st value ≤ 2nd value ≤ 21.5 mA)

C2.….3

error current

Specify error current.

xx.x mA; range: 3…22 mA (condition: outside of extended range)

C2.….4

error condition

The following error conditions can be selected.

Select: error in device (error category [F]) / application error (error category

[F]) / out of specification (error category [S])

C2.….5

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.….6

range

0…100% of the measurement set in Fct. C2.….5

0…xx.xx _ _ _ (format and unit depend on the measurement, see above)

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

limitation

Limitation before applying the time constant.

±

xxx … ±xxx%; range: -150…+150%

C2.….9

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.….10

time constant

Range: 000.1…100 s

C2.….11

special function

Select: off (switched off) /

automatic range (range is changed automatically, extended lower range,

only makes sense together with a status output) /

external range (change by control input, extended lower range, control input

must also be activated)

C2.….12

threshold

Appears only when Fct. C2.….11 threshold is activated between extended

and normal range. The automatic range function always changes from the

extended to the normal range when the 100% current is reached.

The upper 100% value of the hysteresis is then = 0. The threshold is then the

hysteresis value, instead of "threshold ± hysteresis" as shown in the display.

Range: 5.0…80%

(1st value = switching point / 2nd value = hysteresis),

condition: 2nd value ≤ 1st value

C2.….13

information

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

circuit board

C2.….14

simulation
