- Auto1 – the maximum time interval between pulses for minimum flow
- 16 [s];
-
FUnCt – mathematical functions - for frequency measurement should
be set to oFF;
- Cnt1 – set to value 1 (averaging current measurements every second).
Then set the individual characteristics:
-
IndCp – set 2 points;
- X1 – set – 0 [Hz], Y1 set the corresponding flow 0 m 3 /h;
- X2 – set 1 pulse – 1 [Hz], Y2 set the corresponding flow 3600 m 3 /h.
Example 2 Programming the analog output: if you want to program the
analog output as a signal 4...20 mA proportional to flow: 4 mA - 0 m
3 / h,
20 mA - 125 m 3 /h, set the output parameters as follows:
- P_An – set InP1;
- AnL set the value 0;
- AnH set the value 125;
- typA set the type 4_20A (4..20mA).
Example 3 Programming the alarm output working with time delay:
if we want the alarm 1 to work in the range of flow from 1 m
3 /h
to 30 m 3 /h and to be activated after 10 seconds, set the alarm parame-
ters as follows:
-
P_A1 – set InP1;
- PrL1- set the value 1;
- PrH1 -set the value 30;
- typ1 -set the type on;
- dLY1- set the value 10;
- LEd1 – if an alarm indication is needed, it should be set to on, otherwise to oFF.
