6.8 External analog 0-10 V controller

The expansion modules, type MC xx, have an input
for an external 0-10 VDC analog signal transmitter
(terminals 11 and 12). Via this input, the pump can
be controlled by an external controller if the pump
has been set to one of the following control modes:
• Constant curve.
The external analog signal will set the pump curve
within the range from the min. curve to the con-
stant curve selected according to the characteris-
tic in fig. 19.
• Constant or proportional pressure control.
The external analog signal will control the setpoint
for the pump head between the setpoint corre-
sponding to the min. curve and the setpoint se-
lected according to the characteristic in fig. 19.
At an input voltage lower than 0.5 V, the pump will
operate according to the min. curve. The setpoint
cannot be changed.
The setpoint can only be changed when the input
voltage is higher than 0.5 V.

Note:
• The max. curve input, terminals 7 and 10, must be
open.
• The min. curve input, terminals 7 and 9, must be
closed.

Note: As will appear from the above figure, the
number of curves that can be selected via the exter-
nal analog signal will depend on the setpoint of the

6.9 Deactivating the control panel

Can be set by means of the R100.
The buttons on the pump control panel can be deac-
tivated to prevent unauthorized persons from operat-
ing the pump.

6.10 Wireless remote control

For wireless operation and reading of data, use the
Grundfos remote control R100.
For application of the remote control, see section
7.4 R100.
