With the control switched off run the power cable to a suitable 12 volt dc
power source. This must have permanent power and not be switched
through the ignition or data may be lost at power off. Brown or red core
for positive and blue or black for negative. The control is reverse polarity
protected.
Run the wheel sensor cable, identified with the protection sleave, down
through the cab to a suitable position on the axle of the wheel. Fashion a
bracket to mount the wheel sensor with ½ inch hole or cable tie the sensor
in a suitable position. Mount the powerful linear magnet onto the wheel
hub with a suitable epoxy glue. Check that the magnet will not catch the
sensor and will pass within 25mm of the sensor.
Run the machine cut off sensor cable, identified as the sensor without the
protection sleeve down to a position where the machine will move at
headlands. When the magnet is close to this sensor the area counters are
disabled, but the speed displays are still enabled. There are many
possibilities for positioning this sensor,
•
Lever movements within the cab,
•
Three point linkage movements at the headlands,
•
Arm movements on the machine.
•
Cut the sensor off and fit to spare terminals on a spray cut-off switch
•
Short circuit to disable the area count.
Check again that the sensor comes within 25mm of the magnet when the
unit moves.
Circumference and Width measurements.
In the start up procedure the control allows for the input of the wheel
circumference and the width of the machine.
Circumference, The measurement required is actually the distance the
machine moves between each pass of the sensor.
For the magnet fitted to the wheel.
1.
mark the ground and the wheel.
2.
drive in a straight line with a second person counting the number of
wheel turns. Stop at ten turns precisely.
3.
Measure the distance travelled and divide by ten.
4.
Keep a record of this value for future reference.
Width is input as span of the machine, to 25.6 m maximum
