When moving the metering unit by more than 30 mm, rotate metering
unit to avoid crushing seeds !
IMPORTANT

When seeding in « small seed » position, the control box must also be
set on the « small seed » position!

D Work and display settings
The following settings and displays are vital (bold) or can be made in view of the work to
carry out :
1) Setting the point of reference
2) Calibration of the opening (flow control)
3) Programming the nominal seed application rate (100%)
4) Adjusting the metering unit to the nominal seed application rate
5) Programming the seed application rate adjustment level
6) Distribution adjustment of the chosen seed application rate
7) Setting the null flow rate (in case of maintenance)
D 1 Setting the point of reference
Should their be a power cut during a motor manoeuvre or due to its removal, the point of
reference must be newly calibrated.
It must be checked at work begin, when changing the seed type or at least once a day!
Press key
The screen displays the theoretical point of reference: it must be
adjusted to an identical position corresponding to the current real
opening position of the metering unit.
