5.13 F/R mode, forward/reverse flow measurement
•
Refer to Sect. 2.6 for electrical connection of outputs.
•
Define direction of forward (normal) flow, see Fct. 3.02, subfunction “FLOW DIR.”:
in conjunction with F/R operation, set the direction for the forward flow here.
“+” signifies the same direction as shown by the arrow on the primary head,
“–” signifies the opposite direction.
•
Set the status output to ”F/ R INDIC.”, see Fct. 1.07.
•
Current and/or pulse output must be set to “2 DIR.”, see Fct. 1.05 and 1.06, subfunctions
“FUNCT. I” and “FUNCT. B1”.
