System Overview
The canlink 3500 is a flexible instrument designed to fulfil a variety of monitoring, guidance and
control operations using GPS equipment.
The canlink VRC cab module is setup to run variable rate control of the airseeder through a
processor (pod), mounted on the airseeder that manages up to 4 bin metering units and monitors
essential airseeder functions.
When calibrating the bins, seed and fertiliser calibration factors can be stored for up to 24 product
names, saving considerable time in the field when leaving one crop and entering another. Product
names can be edited to reflect specific seed varieties or fertiliser names.
Trip names can be edited to reflect true field names or numbers. Records of actual product areas
and weights are automatically maintained for each trip as well as overall totals of each product
applied.
Product rates set for each bin, can be pre-programmed for up to 100 trips (fields) then simply
recalled by the operator when required. Bins can be individually switched ‘off’or ‘on’from the cab
and application rates can be manually increased or decreased in predefined steps.
Selected rates are automatically governed by ground speed and machine operation can be stopped
at any time by pressing the “RUN/HOLD”key or by lifting the implement, if an optional ram
position sensor is installed.
The canlink provides monitoring of twin fan speed, dual air pressure, bin levels and product
metering shafts with selectable alarm points on critical functions and a control lockout if fan rpm is
too slow.
After initial installation of tractor components, refer to the airseeder manufacturer’s instructions for
correct configuration of bin controls, sensors, machine parameters and recommended alarm points.
See Steps 2 to 5 of the Setup section for instructions. Follow the procedure for product calibration
in Step 3 after initial setup is completed.
All system configuration and calibration factors including product and trip names are permanently
stored in the canlink for reuse at any time. It is recommended to recheck calibration factors before
each sowing season to account for variations in product densities.
A new feature now available on the canlink 3500 platform is parallel guidance. In guidance mode,
activated by pressing the “MODE”key a virtual road, steering prompts, row counter, heading and
cross track error are displayed. A boundary and headland function enables field area to be
calculated while notifying the operator when headland areas have been entered.
With GPS/DGPS connected to the canlink, the data card slot allows application rates to be logged,
for comparison with yield maps. With DGPS/GPS and an application map using adata card, the
canlink will automatically apply the rates assigned in the map.
Future product developments can be uploaded via the data card slot.

DC Motor
1. Check “MOTOR CALIBRATION”screen is displayed. See below.
2. Press the bottom “START”softkey.
3. Press the green button on the pod. The motor will run for 5 seconds at maximum speed.
Caution!
Product will be metered if the bin is not empty.
4. Once the motor stops press the bottom “END”softkey.
5. The “MAX RPM”, “PWM”and “FAC”factors will be updated, indicating the drive is now
calibrated.
Control Factors
PPM: The number of pulses per minute generated by the motor at full speed. This value
should closely match the motor’s rpm specification. In some cases it will be a multiple
of the motor’s rpm depending on the number of feedback magnets used.
PWM: Pulse width modulation.
FAC: A control factor related to the motor’s pulses per minute (ppm) value. The higher this
value, the slower or more damped the control will be.
