8.4.4 Setpoint (1.2.2)
Fig. 10 Setpoint
Description
The display shows the selected setpoint and whether it comes
from CU 352 or an external bus.
It also shows all seven possible setpoints from CU 352, (for
closed- and open-loop control). At the same time, the selected
setpoint is shown.
As it is a status display, no settings can be made.
Setpoints can be changed in the menu "Operation" or "Settings".
See section
8.7.3 Alternative setpoints (4.1.2) .
8.4.5 Setpoint influence (1.2.3)
Fig. 11 Setpoint influence
Description
The selected setpoint can be influenced by parameters. The
parameters are shown as a percentage from 0 to 100 % or as a
pressure measured in bar. They can only reduce the setpoint, as
the influence in percentage divided with 100 is multiplied with the
selected setpoint:
Actual setpoint (SP) = selected setpoint x influence (1) x
influence (2) x etc.
The display shows the parameters influencing the selected
setpoint and the percentage or value of influence.
You can set some of the possible parameters in the display
8.7.5 External setpoint influence (4.1.3) . The parameter "Low flow
boost" is set as a start/stop band as a percentage of the setpoint
set in the display
8.7.24 Stop function (4.3.1) . The parameter is
set as a percentage in the display 8.7.10 Proportional pressure
(4.1.7) .
Finally, the resulting actual setpoint (SP) is shown.
8.4.6 Measured values (1.2.4)
Fig. 12 Measured values
Description
The display gives a general status of all measured and calculated
parameters. In MPC-E systems with a flowmeter, the specific
energy is shown as an average value and actual value (mean
value over the last minute). The average value is based on the
accumulated flow shown as total volume. The total volume and
specific energy average can be reset in this display.
8.4.7 Analog inputs (1.2.5)
Fig. 13 Analog inputs
Description
The display shows an overview of the analog inputs and the
measured values of each input. See sections
8.7.30 Analog
inputs (4.3.8) , 8.7.31 Analog inputs (4.3.8.1 - 4.3.8.7) and
8.7.32 Analog inputs and measured value (4.3.8.1.1 - 4.3.8.7.1) .
The lines "Power consumption" and "Energy
consumption" are only shown in MPC-E systems.
