C3._ Limit Switch X
C3._ Limit Switch X X stands for one of the connection terminals A, B, C or D
_ stands for Fct. C3.2 (A) / C3.3 (B) / C3.4 (C) / C3.5 (D)
C3._.1 Measurement Select:
Volume Flow / Mass Flow / Temperature / Density / Velocity / Sensor
Average / Sensor Deviation / Drive Level / Tube Frequency / Strain 1 /
Strain 2 / 2 Phase Signal
C3._.2 Threshold Switching level, set threshold with hysteresis
xxx.x ±x.xxx (format and unit depend on the measurement, see above)
(1st value = threshold / 2nd value = hysteresis),
condition: 2nd value ≤ 1st value
C3._.3 Polarity Set polarity; the flow direction in C1.3.2 must be noted!
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)
C3._.4 Time Constant Range: 000.1…100 s
C3._.5 Invert Signal Select:
Off (activated output: switch closed) /
On (activated output: switch open)
C3._.6 Information Serial no. of the I/O board, software version no. and production date of the
circuit board
C3._.7 Simulation Sequence see B1._ Limit Switch X
C3._ Control Input X
C3._ Control Input X
C3._.1 Mode X stands for connection terminal A or B
_ stands for Fct. C3.2 (A) / C3.3 (B)
Off (control input switched off) /
Hold All Outputs (hold actual values, not display and totalisers) /
Hold Output Y (hold actual values) /
All Outputs To Zero (actual values = 0%, not display and totalisers) /
Output Y To Zero (actual value = 0%) /
All Totalisers (reset all totalisers to "0") /
Totaliser "Z" Reset (set totaliser 1, 2 or 3 to "0") /
Stop All Totalisers /
Stop counter "Z" (stops counter 1, 2 or 3) /
Zero Outp.+Stop Tot. (all outputs 0%, stop all totalisers, not the display) /
External Range Y (control input for external range of current output Y) - also
make this setting on current output Y (no check if current output Y is
available) /
Error Reset (all resettable errors are deleted) /
Calibrate Zero
C3._.2 Invert Signal Select:
Off (activated output: switch closed) /
On (activated output: switch open)
C3._.3 Information Serial no. of the I/O board, software version no. and production date of the
circuit board
C3._.4 Simulation Sequence see B1._ Control Input X
