Pressure monitoring in the two chamber hopper
If the implement is equipped with a hopper with
two chambers, an overpressure is generated in
the hopper by the running fan.
The pressure gauges (Fig. 119) on the front wall
of the implement show the air pressure in the
chambers 1 (front) and 2 (rear).
Fig. 119
The pressure difference must not be greater
than 5 mbar.
If the required air pressure is not reached, check
the system for leaks. Amongst other things,
check if the hopper cover is closed.
Air distributor
Implements with a two-chamber hopper and two
distributor heads are equipped with an air
distributor. The air distributor is used to set the
same amount of air in both conveyor sections.
