•
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 “SIGN I” or “SIGN P”, see Fct. 1.06 or 1.07, “STATUS B1 or B2”.
For dynamic response of the outputs with “SIGN I” or “SIGN P” see Sect. 5.8.
•
Current and/or pulse output must be set to “2 DIR.”, see Fct. 1.05 and 1.06, subfunctions
“FUNCT. I” and “FUNCT. B1”.
