7.4 Menu OPERATION

When communication has been established, menu
OPERATION appears in the display.
7.4.1 Setpoint
This display depends on the control mode selected
in the display "Control mode" in menu INSTALLA-
TION.
If the pump is remote- or forced-controlled via exter-
nal signals, the number of possible settings will be
reduced, see section 7.7 Priority of settings . At-
tempts to change the settings will result in an indica-
tion in the display saying that the pump is remote-
controlled and changes therefore cannot be made.
The following example of display will appear if the
pump is in constant-pressure control mode.
In this display, the desired head is set.
Furthermore, it is possible to choose between the
following operating modes:
• Stop ,
• Min . (min. curve),
• Max . (max. curve).
This display will be a little different in the case of pro-
portional-pressure control or constant curve duty.
The actual duty point of the pump is indicated by a
square in the Q/H field. The pump cannot register
very low flow rates, and the square will therefore dis-
appear.
7.4.2 Operating mode
Select one of the following operating modes:
• Stop ,
• Min . (min. curve),
• Normal (proportional pressure, constant pressure
or constant curve),
• Max . (max. curve).
7.4.3 Fault indications
If the pump is faulty, the cause will appear in this dis-
play.
18
Possible causes:
• Phase failure ,
• Pump blocked ,
• Undervoltage ,
• Defective pressure/temperature sensor ,
• Internal fault (fault in electronics),
• Fault in master/slave communication .
The fault indication can be reset in this display. If the
fault cause has not disappeared when resetting is at-
tempted, this will be indicated in the display.

7.5 Menu STATUS

The displays appearing in this menu are status dis-
plays only. It is not possible to change or set values.
The actual values in the display are stated as a
guide.
7.5.1 Actual setpoint
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 trans-
mitter or if temperature influence or proportional-
pressure control is activated.
7.5.2 Operating mode
This display shows the actual operating mode ( Stop,
Min., Normal or Max. ) and where is was selected
( Pump, R100, BUS or External ).
7.5.3 Head and flow
Very low flows cannot be registered, and the R100
will show "<" in front of the lowest possible value of
the pump in question.
