11.1.1 Setpoint setting
Set the desired setpoint by pressing
or
. The setpoint can
be set on any of the pumps in the system and applies to the
complete booster system.
The light fields on the control panel will indicate the setpoint set.
Pump in constant-pressure control mode
The following example applies to a pump in an application where
a pressure sensor gives a feedback to the pump. If the sensor is
retrofitted to the pump, it must be set manually as the pump does
not automatically register a connected sensor.
Figure
shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 3 bar with a sensor measuring
range from 0 to 6 bar. The setting range is equal to the sensor
measuring range.

Setpoint set to 3 bar, constant-pressure control mode
Pump in constant-curve control mode
In constant-curve control mode, the pump performance will lie
between the maximum and minimum curve of the pump. See fig.

Pump in constant-curve control mode
Setting to maximum curve:
• Press
continuously to change over to the maximum curve
of the pump (top light field flashes). When the top light field is
on, press
for 3 seconds until the light field starts flashing.
• To change back, press
continuously until the desired
setpoint is indicated.
Example:
Pump set to maximum curve.
Figure
shows that the top light field is flashing, indicating
maximum curve.

Maximum curve duty
Setting to minimum curve:
• Press
continuously to change over to the minimum curve
of the pump (bottom light field flashes). When the bottom light
field is on, press
for 3 seconds until the light field starts
flashing.
• To change back, press
continuously until the desired
setpoint is indicated.
Example:
Pump set to minimum curve.
Figure
shows that the bottom light field is flashing, indicating
minimum curve.
