Sensor (fill level sensor)
The fill level sensor sends a message to the control
box when it is no longer covered with seed.
The sensitivity of the sensor can be adjusted for the
respective seed type. It is adjusted using the small
slotted screw at the rear of the sensor. (In most
cases, it is not necessary to change the adjustment.)
In addition, the height of the fill level sensor can be
comfortably adjusted from the outside.
To verify the function, an object can be held in front
of the sensor and the LED on the back should light
up.
Calibration test/regulation of the seed rate
The speed of the seeding shaft depends on the spread rate and the forward speed
when operating with sensors. To determine the desired spread rate, you should
perform a calibration test before beginning work.
The seeding tables show the spread rate for the respective seed types in kilograms
per minute (= calibrated quantity).
The spread rate is calculated with the following formula:
SpR =
m
(wgt) x
v
(tractor) x
w
(working)
600
SpR: spread rate in kg/min
m(wgt): desired spread rate in kg/ha
v(tractor): speed of the tractor in km/h
w(working): working width in m
Example:
[kg/min]
1,2
600
[m]
12
[km/h]

[kg/ha]
