Half-width shut down - electrically
In the electric half-width shut down two control
motors control the valves in the Venturi area.
Both motors are controlled in parallel mode by
a control box.
The signals for the right or left switching position
and for middle position will only be released to
the terminal when both valves have reached
their intended position.
¾
Switch off the desired half-width in the termi
-
nal. Both valves will be adjusted - the display
flashes.
¾
The seed and fertiliser quantity is halved.
¾
For the drilled area counter the working width
is automatically halved.
¾
Once the two valves are in right or left switch-
ing position, the switched off half width disap
-
pears from the display.
The half-width shut down function must
be tested in the field.
If the desired switching position has not be
reached on both valves after a certain amount of
time, the terminal will show a corresponding alarm.
The alarm needs to be confirmed and repeats
itself until the fault has been corrected.
Depending on the nature of this fault, the oppo-
site side can first be switched before the shut-off
can be repeated.
If the fault is still present, you can adjust the
valves manually.
Seed flow monitoring with half-width shut
down
Seed flow monitoring is automatically switched off.
Half-width shut down - manual
For the half-width shut down the valve on both
Venturi areas can be manually switched to one
side.
The seed and fertiliser quantity must be halved
in the terminal.
Both metering quantities can be e.g. reduced to
50% via the %-adjustment button.
Please make sure that both metering units are
switched "ON" on the page "Machine data" un-
der "Delta Step".
One can also enter half of the desired quantities
for both metering units in kg/ha.
In both cases the drilled area is counted over
the entire machine width.
If the correct area is strictly required, the working
width must be halved in the machine configura
-
tion. The seed and fertiliser quantity must in this
case not be manually changed.
Tram line with half-width shut down
If a tram line is required with half-width shut
down enabled, one must consider the installation
position of the valves.
Hoses may need to be replugged or adapted to
the control.
Seed flow monitoring with half-width shut
down
If the switched off half-width is equipped with
sensors for seed flow monitoring, these would
indicate corresponding alarm messages in the
terminal.
You can either switch off the seed flow moni
-
toring, or unplug the sensors and correct their
number in the machine configuration.
Note: The sensor numbers can also be entered
into the tram line list. In this case this list would
also need to be updated.
