Setting of the Dosing Quantity
The adjusting screw at the quantity setting valve must be turned until the upper edge of the
floater upper edge has reached the desired value in liters/hour at the scale of the flow
measuring pipe (see Diagram 7, Page - 14 -).
For further Information: see Section 8:
Initial Commissioning
Diagram 7
The contactor shuts off the unit as soon as the floater sinks down (safety circuit).
When processing very small quantities ensure that the floater is actually capable to sink down.
Otherwise there is the possibility that the floater does not shut off even though the flow rate
has decreased to zero (risk of underdosage!!!).
At the standard device, the marking (scaling) at the flow measuring pipe 40 to 400 l/h. As the
shut-off function is no longer warranted for in the lowest section (40l/h), a flow measuring
pipe featuring a display ranging from 15 to150 l/h can alternatively be installed (see Spare
Parts List, Page - 23 -, Item 19).
Attention!
The device and the connected worm conveyor are automatically deactivated by the
contactor as soon as the floater, respectively the quantity sinks beneath the set value.
The prerequisite for this is naturally a precise setting.
