20 i-CON Calibration
(Page 2 of 2)
1. For a
Manual Calibration
Press and hold the Prime button on the
junction box, the larger the quantity dispersed the higher the accuracy
the final calibration factor will be, release the prime button once sufficient
product has been dispensed
1. The estimated dispensed weight (based on the current calibration fac-
tor) is displayed
2. Weigh the product dispensed and then enter the measured weight, and press
3. A new calibration factor is then re-calculated and displayed
4. Your in field min and max speeds will be displayed. If you find that you cannot achieve your desired field
speed, then re-configure the feed roller assembly and repeat the calibration procedure
(see pages 17 and 18 for more details)
5. Touch to save the new factor, it is advised to repeat calibration 2 more times to ensure accuracy
GPS Speed
The i-CON control system is automatically configured to run with GPS receiver supplied and is a simple
plug and play device. This system only works outside and if you are not receiving a GPS signal an alarm
will sound and a display appear on the main screen indicating NO GPS.
Common Calibration Mistakes
Ensure you enter the width and required rate correctly – that the decimal point is in the correct position.
If the rate is 2.5 kg/ha, enter 2.5. (not 25 - which is 25kg/ha)
Remember to deduct the weight of the collection container – weigh only the contents
Ensure you work in grams – not kilograms
Ensure you are working in the mode required – either Kilograms per Hectare or Seeds per Square Metre.
The standard default mode for the i-CON is in Kgs/Ha and you will have to reconfigure the display if you
want to display Seeds per Square Metre. You do not need to enter or change the TGW if working in
Kgs/Ha – only if working in Seeds per Square Metre - Refer to the RDS manual, Section 3, page 21,
Units and TGW
Ensure you check the minimum and maximum speeds displayed, and that they are sensible for your field
operation. This is the speed range that the i-CON can maintain the required application rate, and de-
pends on the width of your machine, the application rate required, and the type and configuration of
feed rolls fitted
Ensure that the speed range will work for you in the field – ensure that your target forward speed will
not be close to either the minimum or the maximum of the range, and that you have some reserve of
speed range above and below the in-field forward speed. Ideally your forward speed will be close to the
middle of the range
If the minimum is too high, for example 4kph then the feed motor will be running too slowly if your
forward speed drops towards the minimum as you set in and lift out of work, and this could result in
missed patches (although the alarm will trigger when either the minimum or maximum speed is
reached)
If the indicated speed range does not work for your operation, you must change the feed roller
configuration or the type of feed roll to apply more or less seed, per revolution of the feed mechanism,
as required. Once completed, recalibrate and note the new speed range.
