8.5.1 Operation (2)
Fig. 17
Operation
Description
The column shows the setting range. In closed-loop control, it
corresponds to the range of the primary sensor, here 0-16 bar.
In open-loop control, the setting range is 0-100 %.
At the left hand of the column, the selected setpoint 1 (A) is
shown, i.e. the value set in the display. At the right hand of the
column, the actual setpoint (B) is shown, i.e. the setpoint acting
as reference for the PI controller. If no kind of external setpoint
influence has been selected, the two values will be identical. The
measured value (discharge pressure) is shown as the grey part of
the column (C). See sections
8.7.5 External setpoint influence
and
8.7.6 Setting of influence function (4.1.3.2)
.
Below the display is a menu line for setting of setpoint 1 and
selection of operating mode, including the operating modes
"Normal" and "Stop". It is possible to select further settings:
system operating mode, control mode, setpoints for closed and
open loop and individual pump control.
