Adjustment

The level indicators are adjusted for optimal sensitivity when delivered.

You must readjust your level indicator according to the different installation position:

  • Detach knurled nut 14.
  • Turn micro switch 12 and
  • press tappet 6 until the micro switch 12 produces an audible "Klick" (working point) when pressing slightly on the diaphragm 4.

The optimal operating point also depends on the filling material. During the micro-adjustment, pay attention:
The micro switch 12 must switch back into its resting position, if the filling material decreases.

  • Now tighten knurled nut 14.
