SECONDARY FUNCTIONS, SEED DRILL
Exactly the same functions can be achieved for seed drills as described above for
fertiliser distributors. The functions require the same sensors and the same keys
are used.
SOW AXLE RPM
Encoding a flow figure of 9999 alters the program in the LH 1200 allowing it to
display RPM. RPM is displayed by pressing the L/Ha. key.
ENCODE:
Press the shown keys in this order.
Key Function
RPM:
NOTE! The "L" key cannot be used when this encodement is used.
SEED RATE MONITORING
It is possible to meter the “flow” of seed using a special sensor, which gives a
suitable number of pulses per revolution. The calibration figure is determined
during the normal calibration procedure for the seed drill.
By encoding the calibration figure as a flow figure, the following functions are
available:
ENCODE:
XXXX is the determined calibration figure in
grams with 2 decimals. Thus, a calibration
figure of 15.00 is encoded as 1500. The
displayed seed rate will be in Kg.
Key Function
Seed rate
Total seed consumption
NOTE!
It is a condition for the above functions that the sensor is correctly
calibrated. A new calibration must take place if the seed drill settings
are altered.
