8. Protection and control functions

8.1 Sensors

The table shows the difference between standard
product and FPV (factory product variant) as to the
number of sensors. FPV sensors can be chosen
individually.

*

Three Pt100 sensors are installed in the pump at the factory, but only one sensor is connected as a
standard. It is not possible to connect all 3 stator thermal sensors if bearing sensors are also connected.
