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 primary setpoint 1 (A) is shown,
i.e. the value set in the display. At the right hand of the column
the current setpoint (B) is shown, i.e. the setpoint acting as
reference for the PI controller. If no kind of setpoint influence has
been selected, the two values are identical. The current
measured value (discharge pressure) is shown as the grey part of
the column (C). See
10.4.5 Setpoint influence (1.2.3)
,
10.7.5 Setpoint influence (4.1.3)
.
Below the top part is a menu line for setting of setpoint 1.
The bottom half of the display makes it possible to go to displays
where operating and control modes as well as forced control of
individual pumps can be selected.
