The motorised valves have a small identification
mark on the underside of the shaft, which shows
the position of the valves.
This enables checking the rotary motion of the
valve and its end position.
Seed flow sensors
The seed flow sensors monitor the seed and
Fertilizer
flow. They alarm in case of
quan-tity changes during placement and in
case of blocked hoses.
If hoses to be closed for tramlines are monitored
with sensors, the numbers of these sensors
must be entered into the DrillManager. These
sensors are then excluded from monitoring when
the tram line is switched - see instructions for
DrillManager.
The distribution head must be regu-
larly checked for foreign objects and
deposits.
These disturb the seed flow and the
function of the valves.
Setting / Operation
Pneumatic system
The distributors for seed and
Fertilizer
are mounted in the middle of the drill.
They distribute and direct both seed and
Fertilizer
to the coulters.
All distribution head components must
be leak tight. Even slightest leaks and
air losses will cause uneven distribution.

The motorised valves for the tram line control
and the sensors for seed flow monitoring are
installed on the distributor.
