Ref Display Description & Settings
C 3.x Control input X
C 3.x.1 Mode
• off
• zero output + stop cnt.
(not display)
• stop all counters
• stop counter 1, 2 or 3
• reset all counters
• reset counter 1, 2 or 3
• error reset
• hold all outputs
(not display, not counters)
• hold output W, Y or Z
• all outputs zero
(not display, not counters)
• output W, Y or Z zero
• range change W, Y or Z
• zero calibration
Note! If two control inputs are provided, they should not be set to the
same operating mode; if they are, only the control input connected to
Term. A is in function!
C 3.x.2 Invert signal
• off High current at input, switch closed activates function
• on Low current at output, switch open activates function
C 3.x.3 Information
Displays the Serial No, Software No, and calibration date of the circuit
board
C 3.x.4 Simulation For sequence, see Test Level Menu, Fct. B 1
C4 I/O Totaliser
C 4.y Totaliser 1, 2 or 3
All functions and settings for both counters are the same! In the fol-
lowing descriptions the “y“ indicates the counter:
Totaliser 1 = C 3.1
Totaliser 2 = C 3.2 Totaliser 3 = C 3.3
C 4.y.1 Function of Totaliser Incremental Total counts only positive values
Decremental Total counts only negative values
Absolute Total counts positive and negative values
off counter is disabled
C 4.y.2 Measurement
• volume flow • mass flow
• concentration total1 • concentration total2
C 4.y.3 Low flow cutoff
xxxx.x … ±xxxx.x unit dependent on measured variable selected
1st value A 2nd value (hysteresis), values around “0“ are set to “0“
C 4.y.4 Time constant xx.x s (setting range 000.0…100.0 s)
C 4.y.5 Preset value
x.xxxxx in the unit selected, max. 8 places (see Fct. C 4.7.10 or 13),
Status output X becomes active when value is reached. Status output
X mode (see Fct. C 3.x.1) must be set to Counter 1/2/3 Preset
C 4.y.6 Reset Total • yes • no
C 4.y.7 Set Total
