Fig. 27: Sensor input 0-10V or 0-20mA

The applied analog signal of 0 V or 0 mA represents the actual value of the pressure at "0
%". The analog signal of 10 V or 20 mA represents the actual value of the pressure at "100
%".

Sensor inputs 2V .. 10 V / 4 mA .. 20 mA:

For 2 V .. 10 V / 4 mA .. 20 mA the motor off section does not apply. The setting values for
linear section and cable break section are shown on the figure Fig.28.

Fig. 28: Sensor input 0-10V or 0-20mA

An analog signal smaller than 1 V or 2 mA is recognised as a cable break. An emergency op-
eration speed is then used as emergency operation. For this purpose the emergency opera-
tion must be set to "Pump ON" in the menu "Control setting - Emergency operation". If the
emergency operation is set to "Pump OFF", the motor of the pump is switched off when a
cable break is detected. The applied analog signal of 1 ... 2 V or 2 ... 4 mA represents the ac-
tual value of the pressure at "0 %". The analog signal of 10 V or 20 mA represents the ac-
tual value of the pressure at "100 %".

Application and function of the
Wilo Net interface

Wilo Net is a bus system which enables up to 21 Wilo products (participants) to communic-
ate with one another.

Application for:

•

Double pumps consisting of two participants

Bus topology:

The bus topology consists of multiple participants (pumps), which are connected in series.
The participants are connected via a shared cable. The bus has to be terminated on both
ends of the cable. This is done for the two external pumps in the pump menu. All other sub-
scribers should not have activated termination. An individual address (Wilo Net ID) must be
assigned to all bus participants. This address is set in the pump menu of the respective
pump.

To terminate the pumps:

In the "Settings" menu , select:
