8.2 Description of functions

The description of functions is based on the four main menus of the
CU 352 control unit:
• Status
• Operation
• Alarm
• Settings.
The functions apply to all control variants unless otherwise stated.

8.3 Status (1)

appears if the buttons of the control panel remain untouched for
15 minutes.

Description
No settings can be made in this menu.
The actual value (process value, PV) of the control parameter,
usually the outlet pressure, is shown in the upper right corner (G)
together with the selected setpoint (SP) (H).
The upper half of the display (A) shows a graphic illustration of the
system. The selected measuring parameters are shown with sensor
symbol and actual value.
In MPC-E systems where the differential pressure across the
pumps and pump curve data are known, the display shows the
estimated flow rate when the flow rate and speed of the pumps are
within a range where it is possible to estimate the flow rate.
≈ : This indicates that the flow rate is an estimated value.
The estimated flow rate may differ from a measured value.
In the middle of the display, an information field (I) is shown if any of
the following events occurs:
• Limited operation due to standby pump
• Proportional-pressure influence active
• External setpoint influence active
• Alternative setpoint active
• Low flow boost active
• Pressure relief active
• Clock program active
• Remote-controlled via GENI (RS-485)
• Limited due to reduced operation
• Stopped due to low flow.
