NOTICE
Note the instructions for the Digital Data Interface!
Read the separate instructions for the Digital Data Interface and comply with them.
The Digital Data Interface evaluates all available sensors. Use the graphical user inter-
face of the Digital Data Interface to display current values and set the limit parameters.
A warning message or alarm signal is output upon exceeding the limit parameters. The
motor winding additionally features PTC sensors to enable secure pump deactivation.
