Max. pressure flow (010)
Entry
Enter maximum pressure of primry element.
See layout sheet of primary element. This pressure is assigned to the flow defined in
the "
Max. flow
"
(009)
parameter.
!
Note!
Use the "
Lienar/Sqroot
"
(055)
parameter to specify the current signal for the "Flow"
measuring mode. The following applies for the "linear" setting:
If you enter a new value for "
Max. pressure flow
"
(010)
, the value for "
Set URV
"
(014)
is also changed. Use the "
Set URV
"
(014)
parameter to assign a presure value to
the upper current value. If you want to assign the upper current value a value other than
that for "Max. press. flow" (010), you must enter the desired value for "
Set URV
"
(014)
.
Factory setting:
Upper range limit (URL) of the sensor
Set low-flow cut-off (049)
Entry
Enter switch-on point of the flow-flow cut-off.
Thje hysteresis between the switch-on point and the switch-off point is always 1 % of the
maximum flow value.
Input range:
0...50 % of the end flow value t (
"Max. flow" (009)
).
P01-PMD7xxxx-05-xx-xx-xx-000
Factory setting:
5 % (of the maximum flow value)
Flow (018)
Display
Displays the present flow value.
