Analog Output - Grundfos TPE 2 Series Installation And Operating Instructions Manual

14.14 Analog output

Whether the analog output is available or not, depends on the
functional module fitted in the pump:

Analog output
* See section
22. Identifying the functional
The analog output enables the transfer of certain operating data
to external control systems.
To set the analog output, make the settings below.
