7 Operation
After power on, the unit is ready for operation.
The unit detects the volumetric flow quantity and switches the output according to
the setting.
• Output closed (LED = ON), if volumetric flow quantity ≥ switch point.
• Output open (LED = OFF), if volumetric flow quantity < switch point.
8 Technical data and scale drawing

9 Maintenance, repair, disposal
If used correctly, no maintenance and repair measures are necessary.
In case of strongly polluted media: mount a filter before the inlet (IN). Recommen-
dation: Use a 200-micron filter.
Only the manufacturer is allowed to repair the unit.
After use dispose of the unit in an environmentally friendly way in accordance with
