3. Setting the pump
E-pumps can be set to two control modes, i.e. controlled and un-
controlled operation, fig. 8.
In
controlled
-operation mode, the pump will adjust its perform-
ance to the desired setpoint for the control parameter (pressure,
differential pressure, temperature, differential temperature or
flow).
In
uncontrolled
-operation mode, the pump will operate accord-
ing to the constant curve set.
Fig. 8
Pump in controlled-operation mode (differential-
pressure control) and in uncontrolled-operation mode
The pumps have been factory-set to uncontrolled operation, see
section
In addition to normal operation (controlled or uncontrolled opera-
tion), the following operating modes can be selected,
Stop
,
Min
.
or
Max
., fig. 9.
Fig. 9
Min. and max. curves
The max. curve can for instance be used in connection with the
venting procedure during installation.
The min. curve can be used in periods in which a minimum flow is
required.
The operating modes (Stop, Normal, Min., Max.) can all be set on
the pump control panel.
If the electricity supply to the pump is disconnected, the pump
setting will be stored.
The remote control R100 offers additional possibilities of setting
and status displays, see section
3.1 Factory setting
The pumps have been factory-set to uncontrolled operation.
The setpoint value corresponds to 100% of the maximum pump
performance (see data sheet for the pump).
Other pump settings are marked with
bold-
faced type under each
individual display in sections
and
4. Setting by means of control panel
The pump control panel, fig. 10, incorporates the following:
•
Buttons,
and
, for setpoint setting.
•
Light fields, yellow, for indication of setpoint.
•
Indicator lights, green (operation) and red (fault).

4.1 Setpoint setting
The desired setpoint is set by pressing the button
or
.
The light fields on the control panel will indicate the setpoint set.
4.2 Pump in controlled-operation mode
(differential pressure control)
Example:
Figure 11 shows that the light fields 5 and 6 are activated, indicat-
ing a desired setpoint of 4 m with a sensor measuring range from
0 to 8 m. The setting range is equal to the sensor measuring
range (see sensor nameplate).

Setpoint set to 4 m (differential pressure control)
4.3 Pump in uncontrolled-operation mode
Example:
In uncontrolled-operation mode, the pump performance is set
within the range from min. to max. curve, fig. 12.
