C2. .1 mode Off (control input switched off)
Hold all outputs (hold current values, not display and counters)
Output Y (hold current values)
All outputs to zero (current values = 0%, not display and counters)
Output Y to zero (current value = 0%)
All counters (reset all counters to "0")
Counter "Z" reset (set counter 1, 2 or 3 to "0")
Stop all counters
Stop counter "Z" (stops counter 1, 2 or 3)
Zero outp.+stop Cnt. (all outputs 0%, stop all counters, 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)
C2. .2 invert signal Select: off / on
C2. .3 information 1 st line: serial number of the I/O circuit board
2 nd line: software version number
3 rd line: production date of the circuit board
C2. .4 simulation Sequence see B 1. control input X
C3 I/O counter
C3.1 counter 1 Set function of counter
stands for 1, 2, 3
C3.2 counter 2
C3.3 counter 3
C3. .1 funct. of counter Define counter
Select:
Sum counter (counts positive and negative values)
+counter (counts only the positive values)
-counter (counts only the negative values)
Off (counter is switched off)
C3. .2 measurement Selection of the measurement for counter
Select: volume flow / mass flow / corr. volume flow
C3. .3 low flow cutoff Sets output value to "0".
Range: 0.0…20%
1 st value = switching point / 2 nd value = hysteresis
Condition: 2 nd value ≤ 1 st value
C3. .4 time constant Averages measurement
Increasing value improves stability but delays the reaction.
Range: 000.0…100.0 s
C3. .5 preset value If this value is reached, positive or negative, a signal is generated that
can be used for a status output at which "preset counter X" has to be
set.
Preset value (max. 8 digits) x.xxxxx in selected unit, see C5.7.9 + 12
C3. .6 reset counter Sequence see Fct. A3.2, A3.3 and A3.4
