4. Setting the pump
4.1 Pumps without factory-fitted sensor
The pumps have been factory-set to uncontrolled operation.
In
uncontrolled-operation mode , the pump will operate
according to the constant curve set, fig. 15.
Fig. 15 Pump in uncontrolled-operation mode
4.2 Pumps with pressure sensor
The pump can be set to two control modes, i.e. controlled and
uncontrolled operation, fig. 16.
In
controlled-operation mode , the pump will adjust its
performance to the desired setpoint for the control parameter
(pump discharge pressure).
Fig. 16 Pump in controlled-operation mode (pressure control)
and in uncontrolled-operation mode
In addition to normal operation (controlled or uncontrolled
operation), the following operating modes can be selected,
Stop ,
Min . or Max ., fig. 17.
Fig. 17 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
6. Setting by means of R100.
4.3 Factory setting
Pumps without factory-fitted sensor: 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).
Pumps with pressure sensor: The pumps have been factory-set
to controlled operation. The setpoint value corresponds to 50 %
of the sensor measuring range (see sensor nameplate).
Other pump settings are marked with
bold - faced type under each
individual display in sections 6.1 Menu OPERATION and
6.3 Menu INSTALLATION.
5. Setting by means of control panel
The pump control panel, fig. 18 or 19, incorporates the following:
• Buttons,
and , for setpoint setting.
• Light fields, yellow, for indication of setpoint.
• Indicator lights, green (operation) and red (fault).
