8.4 Menu OPERATION

When the communication between the R100 and the
pump has been established, "Contact with" appears
in the display. When the "arrow down" on the R100 is
pressed, the OPERATION menu appears.
The display "Contact with" appears
Note
only once, i.e. when the R100 gets
contact with the pump.
8.4.1 Setpoint
This display depends on the control mode selected
in the display "Control mode" in the INSTALLATION
menu.
If the pump is remote- or forced-controlled via
external signals, the number of possible settings will
be reduced. See section 8.7 Priority of settings.
Attempts to change the settings will result in an
indication in the display saying that the pump is
remote-controlled and that changes therefore cannot
be made.
The following example of display will appear if the
pump is in proportional-pressure control mode.
Set the desired head.
Furthermore, it is possible to select one of these
operating modes:
• Stop
• Min. (min. curve)
• Max. (max. curve).
This display will be a little different in the case of
constant-pressure control or constant-curve duty.
The actual duty point of the pump is indicated by
a square in the Q/H field. No indication at low flow.
8.4.2 Operating mode
Select an operating mode:
• Stop
• Min. (min. curve)
• Normal (proportional pressure, constant pressure
or constant curve)
• Max. (max. curve).

8.4.3 Fault indications
If the pump is faulty, the cause will appear in this
display.
Possible causes:
• Phase failure
• Pump blocked
• Undervoltage
• Defective pressure/temperature sensor
• Internal fault.
The fault indication can be reset in this display. If the
fault cause has not disappeared when resetting is
attempted, this will be indicated in the display.

8.5 Menu STATUS

The displays appearing in this menu are status

Field "Actual setpoint":
Actual setpoint of pump.
Field "corresponding to":
Actual setpoint in % of the setpoint set if the pump
is connected to an external analog 0-10 V signal
transmitter or if temperature influence or
proportional-pressure control is activated.
8.5.2 Operating mode
This display shows the actual operating mode (Stop,
Min., Normal or Max.) and where this was selected
(Pump, R100, Bus or External).
