Menu 3.1.2 Choose speed source
The SmartCom controller can receive a speed input from other
sources than the sprayer wheel sensor, which for natural reasons is
only present on trailed sprayers.
Therefore when selected, lift sprayers can receive input from the
following sources:
• 3.1.2.1 Sprayer Sensor or Radar:
The SmartCom controller receives input from a wheel speed
sensor or from the tractor radar connector.
• 3.1.2.2 Speed via ISOBUS:
The SmartCom controller receives speed input via an ISOBUS
cable from a GPS or from the tractor ECU.
Menu 3.2 Flow calibration
The flow transducer can be calibrated theoretically or calibrated
with clean water by using one of the two practical methods.
The theory method is preferred. But practical methods can be used
in the case that inaccuracies may occur:
μ
ATTENTION! Check of calibration is recommended to be
done at least once during the spraying season. Use the
chart at the back of the book to record the values.
Menu 3.2.1 PPU theory method
1. Preferred method is to read the PPU value on the flow housing.
The picture show the location where the PPU value is stamped into
the flow housing.
μ
ATTENTION! Each flow sensor is calibrated to a specific PPU value.
Therefore no general PPU values can be given.
μ
ATTENTION! PPU indicates the number of pulses which
theoretically come from the flow transducer whilst 1 litre of liquid
passes through.
