1.0 INTRODUCTION
The Farmscan canlink 3500 is a versatile programmable precision farming tool, designed specifically
for agricultural use to provide a reliable and user friendly system.
Programmed as a grape yield monitor it provides the following information: live yield rate, load, area
harvested (total and trip), speed, time, guidance and GPS information.
The canlink 3500 Grape Yield Monitor is a monitoring system with the parallel row guidance
option. There are two selectable modes of operation: yield monitoring with guidance and yield
monitoring only.
The canlink 3500’s data logging function, allows detailed records to be taken during harvesting and
stored on a mmc (multimedia) card. Data from the card can be downloaded onto a personal
computer and maps drawn. These maps can be later used to generate application maps where rates
(eg spray rates) can be assigned to selected areas of the field.
The canlink 3500 Grape Yield monitor features: automatic hold functions, 100 trips and 12 tags
with the ability to customise the name of each trip and tag label. Trip names, tag labels and monitor
calibration and configuration settings can be saved onto a multimedia card and reloaded for later
use. Units can be set to US or metric and clear alarm messages direct the operator to the issues
affecting the monitor’s operation.
The monitor is equipped with a liquid crystal display that can be adjusted for contrast and brightness
to best suit viewing conditions.
The canlink 3500 platform upon which the grape yield monitor operates has been designed to grow
as new applications are integrated. The versatility of the canlink 3500 allows it to be reprogrammed
in the field using a mmc card. Already in place, the 3500 has several yield functions, variable rate for
up to four products, spray control and soil sampling functions.

canlink 3500 Grape Yield Monitor : LOAD CELLS EXPLAINED

3.0 LOAD CELLS EXPLAINED
General
The load cells used in the grape yield monitoring system are hermetically sealed sheer beams. They
are suitable for outside mounting and will operate in wet and dusty conditions.
Mounting Information
The load cells weigh by measuring the bend in the load cell material, therefore it is important that
the fixed end (end with 2 holes) be mounted rigidly and perpendicular to the force applied as
shown below. If using more than one load cell, all cells must be mounted in the same way.
Mounting Upside Down
These load cells will weigh equally well upside down if it is more convenient for installation
purposes. However, the white and green signal wires from the load cell at the junction box end must
be swapped over. That is the green wire goes to where the white wire went and the white wire goes
to where the green wire went. See section 4.4 for more information.
Note: If load cells are mounted with the arrow on the cell being in the same direction in which
force is applied, follow the wiring directions in the manual for correct weigh readings.
Choosing Load Cells
The choice of cells is a compromise between resolution and the maximum load capacity. Load cells
will be damaged if they are overloaded by more than 50%, therefore if extraneous loads (people
walking on the weighing installation) are likely to be experienced, the cells must be selected
accordingly. However, it is no good to choose excessively large capacity cells as the scale resolution
is reduced.
Load Cell Resolution
The resolution of the weighing system is calculated by summing the capacity of each cell in the
system and dividing it by 4000. See below for an example.
Example:
If 4 cells are used each with a 10 kg (22 lbs) capacity, the total scale capacity will be 40 kg (88 lbs)
therefore the smallest weighing increment is 40 ? 4000 = 0.01 kg or 10 grams (~ ½ ounce). If there
is only 0.5 kg (~ 1 lb) on the weigh platform at any time then the inherent accuracy can be no better
than 2% (0.01/0.5 ? 100%).

Updated : 22/11/2005
canlink 3500 Grape Yield Monitor : LOAD CELLS EXPLAINED
6
In the above example if such an installation experiences a load of 60kg (150 lbs), it would be
damaged and consequently not be suitable in a position where people may step on the scales.
Load Cell Output and Wiring
Internally, load cells consist of a bridge configured set of 4 strain elements. An excitation voltage is
applied across the bridge (10 Volts) and an output signal proportional to the load on the cell is
generated on the signal wires. See the diagram below.
The load cell junction box uses + 5 and - 5 Volt excitation, therefore the unloaded cell output is zero
volts.
IMPORTANT !
?? The black wire from the cell must not be connected to the silver braid from the cell. Or else the
negative 5 Volts will be shorted out and the junction box circuit may be damaged.
?? The braid must be connected to the machine ground and the black wire must be connected to
the negative load cell supply voltage.
The output from the load cell is very small so special equipment (at least, a multimeter with a 3
decimal point voltage scale) is needed to measure the voltage generated on the signal wires when
the cell is loaded. Typically there will be only 0.02 Volts when the cell is loaded to capacity.
Loads cells are in spite of this, sturdy and apart from physical overloading they are only likely to
suffer damage from extreme currents such as those generated when arc welding. Therefore never
weld on or near the weigh platform where load cells have been installed!
! Important
Never weld on or near the weigh platform where load cells have been installed!!!

4.0 INSTALLATION
The grape yield monitor uses a number of sensors: a wheel sensor (optional) for distance, area and
speed; a load cell junction box for yield, belt speed and pitch and roll; a GPS for data logging and
speed. This section describes procedures to install these sensors.
4.1 Canlink 3500 MOUNTING BRACKET INSTALLATION
Adhere the two rubber adhesive washers (HG-005) provided in the kit onto the inside of the canlink
3500’s mounting bracket (AH-405). This prevents the monitor from swivelling once mounted.
Mount bracket in a convenient, in-reach, in-view position in the vehicle’s cab.
4.2 WHEEL SENSOR INSTALLATION (optional)
A wheel sensor is optional and a suitable cab loom must be ordered separately. The most commonly
used wheel sensor consists of a reed type sensor and a magnet fitted onto any undriven ground
wheel of the vehicle.
The magnet activates the reed type sensor as it sweeps past.
Alternatively, radar, tail shaft sensors or a speedo cable sensor are available if required. If the monitor
is connected to a GPS, the RMC string will provide speed information.

Bolt the wheel magnet onto the inside of the wheel in a position that allows the
magnet to sweep directly past the wheel sensor within a 5 - 10 mm clearance.
Maximum clearance is 15 mm.
The magnet can be mounted anywhere in a radius from the centre of the wheel.
Nearer to the hub will ensure the best ground clearance.
The sensor must be rigidly bolted to an existing structure, ideally in a protected
position to face the magnet as shown.
If the sensor is mounted on a steered wheel, make sure the sensor moves with the
steering mechanism to maintain constant clearance between the magnet and the
sensor when turning from lock to lock.
NOTE:
?
The magnet and reed type sensor can alternatively be mounted on an axle coming off
one of the vehicle’s wheels. See the diagram below for a sample installation.
To install alternative speed sensors (speedo cable, radar, drive shaft/tail shaft) refer to the instructions
that come with the sensor kit.
4.3 YIELD SENSOR INSTALLATION
The yield sensor is made up of a load cell junction box, a belt sensor and a load cell.
BELT SENSOR INSTALLATION
The belt sensor consisting of a proximity switch and a disc, provides the monitor with a signal to
calculate the belt speed. It is important that the belt sensor gets a number of pulses (5 to 20, more is
better) during the time the same product mass passes over the weigh section. This ensures the
highest degree of accuracy.
The proximity switch registers a signal when it comes into close proximity with a piece of metal
(maximum distance 3 mm or 0.1”).

IMPORTANT! - TARGET DISC SELECTION:
If the belt shaft speed is greater than 500 RPM, install a disc with a lesser number of teeth than the
disc supplied in the kit (contact Farmscan for a suitable disc or remove every second tooth). However,
if the shaft speed is less than 500 RPM install the disc supplied. If unsure of shaft speed see section
6.3 “Diagnosing Problems with the Belt Sensor” once installation is complete.
DISC INSTALLATION:
Use the 8 mm supplied tap, to tap a thread into the end (centre) of the shaft that drives the belt.
Secure the toothed disc to the end of the shaft using the M8 12mm socket head bolt. The disc must
turn in direct proportion to the movement of the belt.
PROXIMITY SWITCH INSTALLATION:
Mount the proximity switch 0.5 mm or 0.02” (or as close as possible) away from the tooth on the
disc that comes closest to the proximity switch. Mount as shown in the diagrams below. The
maximum gap is no more than 2 to 3mm or 0.08 to 0.11”.

Be sure to take into account the wobble in the target disc. The sensor must not be mounted so close
that because of the wobble the disc hits the sensor. Before finalising installation turn the disc by
hand so that the disc completes one whole rotation without hitting the sensor.
NOTE: If sensing off an existing metal
sprocket, the sensor should face the
edge of the tooth. Teeth must be
greater than 13 mm apart.
The turning target disc must not have a wobble in it greater than 1mm. Otherwise, the proximity
switch may not generate a signal from all the teeth on the disc, or the teeth may hit the proximity
switch.
LOAD CELL INSTALLATION
Four load cells are used for the installation. Load cells are mounted onto the frames provided. Two
frames are used with two load cells mounted onto each frame. Each load cell has a sealed ball
bearing, acting as a roller, mounted on its weighing end. Both frames are mounted below the cut
out weighing section so that the belt passing over this section rests on the load cell rollers. The load
cells rollers are level with the rest of the pan.
The cut out weigh section is a 600mm cut out section of the under pan (below conveyor belt). The
rollers transfer the weight on the belt to the load cells. The load cells in turn weigh the material on
the belt and convert the weight to electrical signals which are transferred to the canlink for
processing and display (also logging) in tonnes per hectare.
There are two basic steps involved in the load cell installation. They are cutting a section out of the
pan and mounting the load cells to bottom of the pan.
Load cells come already mounted onto the frames. See the diagram on the next page.

The load cells and frames have been designed to fit all grape harvesters. A diagram of the finished
installation is given below.
Follow the procedure below to construct the weighing section.
LOAD CELL INSTALLATION PROCEDURE:
Step 1
?? Remove the conveyer belt and other items (like side strips) for clear access to the inner pan below
the conveyor belt.
?? At the middle of the conveyer body, measure and mark a section of 600mm, where the weighing
section will be installed.
NOTE: The installation must be at least 1m clear of the cleaning fans.

Updated : 22/11/2005
canlink 3500 Grape Yield Monitor : INSTALLATION
12
?? Carefully cut away this 600mm section with an angle grinder.
Step 2
Mark holes for bolting load cell frame to tray
Both load cell frames must be bolted to the tray at the same distance from the centre line of the tray.
This will vary for different harvesters.
We recommend bolting the frames at a quarter of the tray's width from the centre line as shown on
the diagram above. However, if wear strips are in the way, a distance as close as possible to a quarter
width is fine.
Note
Holes need to be drilled on the low edge of the pan. Eg in between wear strips so that the belt
won’t rub against the bolt head.
Load cell frames are bolted to the tray using stainless steel M8 x 12mm bolts, M8 spring washers and
M8 nylock nuts.
Measure approx 17mm in from the edge of the cut out edge. See diagram below.

Step 3
Before drilling 8mm holes, check that holes in the frame brackets coincide with the holes to be
drilled.
Check that the holes for each frame are in line. The frames must be straight or parallel to the length
of the tray.
When marks and frames line up, drill 8mm holes into the tray.
Step 4
Bolt the frames to the underside of the tray using the supplied M8 bolts and nylock nuts.
?? IMPORTANT! Any stress (twist etc) to the frame must be avoided. Frames must be parallel to
length of tray. Not at an angle.
?? Frame mounting brackets must be tightened so that the top flat part of the bracket is flush with
the underside of the tray.
Step 5
Load Cell Cable Exit
To provide an exit for the load cell cables drill a 25mm hole in the conveyer frame at a position
giving convenient access to the junction box.
Insert the supplied black (HG-664) liquid tight fitting into the drilled hole. This is to reduce the wear
of the cable against sharp edges in the drilled hole. Next feed the load cell cables through the
fitting.
Step 6
Adjust Load Cell Bearing Height

Updated : 22/11/2005
canlink 3500 Grape Yield Monitor : INSTALLATION
14
The height of the load cell bearings needs to be adjusted so that the top of all bearings is level with
the existing pan. To be sure place a straight edge over the cut away section and turn bolt A to adjust
the height. See notes on next page regarding tightening lock nuts.
IMPORTANT: If bolt A is too short to give the correct height, replace it with the M8x55mm bolts
supplied in the kit. Alternatively if bolt A is too long replace it with the M8x40mm bolts supplied in
the kit.
Note:
If the bearings sit lower than level with the pan, weight passing over the cut away section may not
be weighed.
Note – Tightening of nylock nuts:
?? Do not tighten nylock nut underneath bearing bracket all the way. Tighten to allow the
bearing and bracket to swivel freely.
?? Tighten nylock nut underneath mounting platform once correct bearing height has been
established.
Note – Corrugated pans:
For corrugated pans adjust the height of the bearing to be level with the top of the corrugation. See
diagram below.
Note – ‘V’ Shaped pans:
Determine points A and B as shown in the diagram below. Use a straight edge and place it on the
centre of one bearing and run it straight to the cut-out edge of the pan. Adjust the height of the
bearings to be exactly level with points A and B on the cut edges of the pan. See diagram below.

Step 7
?? Put the conveyor belt and other items previously removed, back into their correct position.
Note: the belt rests on the load cells and must be pulled tight to avoid sagging .
?? Verify that the belt touches the load cell bearings by inspecting through wash ports.
?? Move the belt and check that the belt rolls with reasonable ease on the load cell bearings.
IMPORTANT :
To clean the section under the belt and to inspect the load cell installation it is necessary to cut two
to four wash ports (100x50mm) on the sides (1 to 2 on each side) of the conveyor body at about the
height of the load cell. Flaps should be used to close them when not needed.
See the diagram below.
Step 8:
Install a cover over the weigh section to avoid someone walking on it and causing overload damage
to the load cells.
Revision 0
November 2005
Part No. : AM-3500GRM
Updated : 22/11/2005
canlink 3500 Grape Yield Monitor : INSTALLATION
16
?? The cover should be made of heavy-duty material, being strong enough to walk on.
?? The cover should also be shaped and bolted onto the conveyor body in a fashion that it is easily
removable.
?? It should also be of a long enough length so that if anyone stands on the end of the cover, there
is no danger of overload damage being done to the load cells.
LOAD CELL JUNCTION BOX INSTALLATION
Mount the load cell junction box after installing the load cells.
The load cell junction box must be mounted so that whatever pitch or roll the weigh section
experiences, the pitch and roll sensor inside the junction box experiences it in exactly the same way.
Therefore the junction box must be mounted on the external conveyer. A recommended position is
the underside of the conveyer above the hydraulic ram.
Diagrams below show orientation of the junction box to register pitch and roll.
The junction box may be mounted upside down with the lid facing the ground.
Note:
Pitch and roll will still be registered in the same way if the junction box is mounted upside down.
The junction box reads zero pitch and roll when it is oriented as shown in the diagram below.
Revision 0
November 2005
Part No. : AM-3500GRM
Updated : 22/11/2005
canlink 3500 Grape Yield Monitor : INSTALLATION
17
If the junction box and conveyer belt are at angle to the ground when the harvester is level, to zero
the pitch and roll sensor it must be removed and placed on flat ground (as in diagram). It is best
that the junction box be mounted so that it can be easily removed. See section 6.3 to level the pitch
& roll sensor.
Once you have found a position to mount the junction box make up a drill template:
1. Place the junction box on a piece of paper and with a pencil, mark out the 4 holes through the
mounting holes.
2. Adhere the template to the mounting position using adhesive tape.
3. Using a centre hole punch mark the holes.
4. Remove the lid of the junction box and feed the self-tapper screws through the four corner
mounting holes.
5. Screw the self-tappers into position and screw lid back on.
4.4 WIRING INSTALLATION
This section explains the various connections that ensure the system’s complete operation. The
connections to be made are given below. Note power is connected last.
1. Cab loom connection to the canlink 3500
2. Proximity switch connection to load cell junction box
3. Load cell junction box connection to cab loom
4. Connection to power
See page 19 for a diagram of the full system connection scheme.
START
Connect the cab loom (AC-3000GRAPE/T) to the port on the canlink 3500, labelled “LOOM
CONNECTION”.
CONNECTION TO LOAD CELL JUNCTION BOX
Connect the 4 way connector of the cab loom to the junction box. Connect the 3 way connector
of the belt sensor to the load cell junction box. Use the extension cable supplied.
WIRING LOAD CELLS TO JUNCTION BOX:
The wires from the load cell cables have to be soldered into the supplied 4 pin female plugs as
shown below. It has been based on the load cells being mounted so that the applied weight is in the
same direction as the arrow on the load cell.

CONNECTION TO GPS
Connect the GPS unit to the canlink 3500 using the port labelled “RS232 GPS INPUT” at the back
of the monitor. If you have a canlink with an internal GPS, this port may be used to add differential
corrections.
CONNECTION TO POWER
Connect the positive (red) and negative (black) power cables from the cab loom direct to a 12 Volt
DC battery. This provides power to the canlink 3500.

Do not connect power until all other installation is finished.
Connect direct to 12 Volt DC battery terminals where possible.
Do not connect the power cable to a starter motor, alternator etc, as this may cause
interference.
Do not connect power cable’s negative direct to the chassis of the machine – it must be
connected to the battery’s negative terminal.
Do not power other instruments off the monitor power cable. Such as a two way
radio.
Use the provided cable ties to secure the power cable safely away from hot or moving
parts.
Connection to battery terminal bolts must be kept clean and tight. See the diagram

4.5 SETTING THE LOAD CELL OFFSET
As dead weight and the number of load cells in an installation varies, the load cell offset can not be
set by the factory. Before calibrating the system the junction box offset must be set and checked to
count up with weight applied.
With installation complete and belt back in place and canlink 3500 turned on:
1. make sure the “ZERO” value is set to zero on the “CALIBRATION” screen;
2. take the lid off the junction box and locate the blue trim pot “RV1” on the circuit board, see the
diagram below;
3. go to the “SENSOR” screen;
4. using a screwdriver turn the gold coloured screw on the blue trim pot “RV1” to adjust the

6.1 CALIBRATION
Selecting the “CALIBRATION” menu item displays the screen shown below. This screen is used to
fine tune canlink load values to weighed values.
LOAD CELL LEVEL
This is a number representing the current weight of material being weighed by the load cells.
Before starting the calibration procedure “RV1” in the junction box must be set. See section
4.5 “SETTING LOAD CELL OFFSET”.
ZERO
Sets the zero point on the yield sensor’s load cells which corresponds to zero harvested
weight.
PROCEDURE TO DETERMINE THE LOAD CELL ZERO
To find and set the zero point follow the procedure below.
*
When pulling out of crop, observe the “LOAD CELL LEVEL” drop as the harvester finishes
discharging product and stabilises to the residual weight. This is the load cell zero point.
*
Run the harvester being empty for 20 seconds to get a good average then press the vertical
softkey below “ZERO” and the load cell zero point will be updated with the same number as
the “LOAD CELL LEVEL”.
The yield sensor reading is affected by dirt build up, it is recommended to check and reset the load
cell zero regularly.
It is important to re zero before every harvest run.

DIVIDER
For higher accuracy the canlink registers and sums the weight of product several times while
it travels over the weigh platform. The number of times the product was weighed is the
divider factor. The divider factor reduces the summed or accumulated weight to the product
weight.
As the canlink ‘weighs’ material at each pulse from the belt sensor the divider factor is the
number of pulses output from the belt sensor during the time taken for material to travel over
the weigh platform.
A procedure to calculate the “DIVIDER” factor is given below.
DIVIDER CALIBRATION PROCEDURE
INITIAL CALIBRATION
1. Mark the belt at the beginning of the weigh platform.
2. Move belt forward manually and begin counting the number of target disc teeth passing the belt
sensor.
3. Stop counting when the mark on the belt reaches the end of the weigh platform. Write down
the result (typically about 40).
4. Enter the number of teeth into “DIVIDER” and do not press “UPDATE”!
FINAL CALIBRATION
1. Reset the “LOAD” reading in the main screen to zero.
2. Start harvesting and DO NOT RESET THE LOAD VALUE. Continue harvesting and when
stopped, weigh the harvest without resetting the load value!
3. Compare load reading on canlink (main screen) with harvested actual weight. If the same then
the initial value for divider was correct, no further calibration needed. If different go to step 4.
4. Enter the actual harvested weight into “ACTUAL” (“CALIBRATION” screen) and press the
“UPDATE” softkey for 3 seconds. The divider value will now be updated.
NOTE :
Changing the “DIVIDER” will from that moment on change the way the “LOAD” value in
the main screen accumulates.

6.2 MACHINE
Selecting “MACHINE” from the calibration menu will display the “MACHINE MENU” shown below.
This screen is used to enter and calculate calibration factors, which are required for the calculation of
speed, area and yield rate.
WIDTH
Enter the width of the machine’s harvesting path (swath) in metres or inches.
WHEEL FACTOR
The “WHEEL FACTOR” is the distance travelled by the vehicle for each rotation of the wheel
or axle where the speed sensor is fitted. The procedure to determine the wheel factor is given
on the next page.
With a GPS connected to the monitor, setting the wheel factor to zero will configure the
monitor to use the RMC string for speed input. Thus displaying speed without a wheel
sensor.
DISTANCE
The distance travelled in metres or yards during the wheel factor calibration procedure. This
value is entered manually. The “DISTANCE” value resets to 100 metres or 100 yards.
COUNT WHEEL PULSE
The “COUNT WHEEL PULSE” is used to calculate the wheel factor. It displays a count of how
many complete revolutions the vehicle’s wheel makes. The “COUNT WHEEL PULSE” can be
reset at anytime by highlighting this field with the bottom vertical softkey and using the
“RESET” key.

1.
Measurement procedure must be performed in working conditions, not on a sealed
road (recheck measurement when moving from hard to soft working conditions).
2.
Switch monitor on and select the “COUNT WHEEL PULSE” mode from the “MACHINE
MENU” screen.
3.
Creep vehicle forward and stop exactly on a pulse count, then press the “RESET” key to bring
the “COUNT WHEEL PULSE” reading back to zero.
4.
Peg ground at bottom centre of any wheel as a starting reference point for measurement.
5.
Drive forward for a reasonable distance and stop exactly on a pulse count.
Eg

Selecting “DISPLAY” on the calibration menu screen will bring up the display screen as shown
below.
CONTRAST
The contrast control will lighten or darken the pixels that make up the screen
(Liquid Crystal Display). Increasing or decreasing the “contrast setting” changes
the contrast.
To change the display contrast, select the contrast setting using the softkey
adjacent to it. A cursor then highlights the contrast setting number. Increasing
the number makes the display darker, decreasing the number makes the display
lighter. Left and right arrow keys also adjust the contrast setting.
NOTES:
?? The LCD contrast may change while the unit is operating. As the ambient temperature rises the
display may darken. This will require that the contrast be adjusted as necessary.
?? The contrast may be adjusted when in the main screen by simply using the left and right arrow
keys. Left arrow makes the display lighter and the right arrow makes the display darker.
BACKLIGHT:
Toggles the backlighting between “LOW”, “MED” and “HIGH”. The low and medium settings are
better suited to night operation while the high setting is better for day operation

PROCEDURE TO DETERMINE PITCH AND ROLL CORRECTIONS
The standard pitch and roll correction is 0.3% if product has the tendency to roll back it may be
necessary to change this.
CALIBRATING THE PITCH & ROLL SENSOR
The pitch and roll sensor is calibrated by making the load cell junction box level with flat ground
and then zeroing the pitch and roll readings from the “MASS DIAGNOSTIC SCREEN”. See section
6.3 to zero the pitch and roll sensor.
WEIGH SCALE
Is the factor used to calibrate the yield sensor.
Before following the procedure below make sure the blue trim pot in the junction box has
been adjusted via the procedure in section 4.5 “SETTING THE LOAD CELL OFFSET”.
WEIGH SCALE CALIBRATION PROCEDURE
?? Place a known weight directly above the load cell on the weigh area of the belt. Make sure the
weight is below the capacity of the load cell.
?? Make sure there is a value in the “ATOD” item (4096 maximum).
?? Enter the actual weight of material on the yield sensor into the monitor under the “ACTUAL”
item.
?? Press and hold the “UPDATE” softkey for 3 seconds on the bottom of the screen and the monitor
will automatically calculate the weigh scale factor by dividing the actual weight by the “ATOD”
value. An example is given below.

NOTE :
Make sure the system has been zeroed first.
6.5 DIAGNOSE
Pressing the softkey adjacent to the show test screen item displays the “SYSTEM DIAGNOSTIC
SCREEN”. This screen is used to check the operation of the yield sensor and to zero the pitch and
roll sensor for calibration. The remainder of the screen displays system status information.
To zero the pitch and roll sensor:
?? Make sure the load cell junction box is flat (bottom face parallel with ground), either the junction
box must be taken off the machine and laid flat or the machine must be tilted to make the sensor
parallel or level with the ground (use a spirit level to confirm this).
?? Then press the “ZERO” softkey and the pitch and roll figures will zero.
?? Remount the junction box (if required) and check using the diagnostic screen that the pitch and
roll readings are correct.
Diagnosing Problems with the Belt Sensor:
Sensor Misalignment!
In the second row of the diagnostic screen the number of pulse counts from the belt sensor is
displayed. When the system is operating well the count reading should be steady within a narrow
range of counts per second.
If the count rpm is not steady that is it fluctuates constantly between say 5, 10 and 20 then the belt
speed sensor (proximity switch) is not aligned correctly with the supplied toothed disc being turned
by the belt. See section 4.4 to realign the sensor with the disc for a stable pulse count.

GMT OFFSET
Pressing the softkey corresponding to “GMT OFFSET” highlights the time zone offset, use the arrow
keys to set. The time zone offset is used to correct the Greenwich mean time issued by the GPS so
that the unit will display the correct time relative to the time zone the user is in.
GPS
Pressing the softkey adjacent to the GPS item toggles the cursor between the baud rate and the
“ENABLED/DISABLED” indicator. Once a selection has been made pressing the up and down arrow
keys changes the baud rate or either disables/enables the GPS.
The yield monitor uses the GGA and VTG strings for position and speed, it is important that these
strings are enabled on your gps.
To log yield data the GPS must output the GGA and VTG strings.
IMPORTANT!
?? The GPS output rate must be 1Hz OR 5Hz setting! Note: For Guidance 5Hz is required.
?? The GPS should output the GGA and VTG strings only. These strings are sufficient for data
logging.
6.10 DATA CARD
NOTE: The "LOAD" softkey and the "LIST MAP FILES" items have no function in grape yield.
The monitor operates using a 32Mb MMC (MultiMedia Card). When installed the card will be
detected and displayed automatically in the "DATA CARD" screen.
If no card has been inserted or there has been an error in reading the card or "DATA CARD" is set to
"DISABLED" then the capacity displayed will be 0 MB.
Please see the next page for information on MultiMedia data cards.

MultiMedia CARD INFORMATION
MultiMedia cards are a removable storage media currently being used by many devices such as
digital cameras and digital voice recorders to record/store data. In the Windows environment using a
USB card reader, multimedia cards act just like another hard drive, where files can be stored and
removed.
While any file can be stored on a multimedia card we recommend that when using the mmc card to
upload new software onto the canlink or log data there are only canlink related files such as
software (".sof") and log files (".log").
Please read through the information below as it contains important information relating to the use
of mmc data cards with different windows operating systems.
INSERTING/REMOVING THE MMC CARD
1. The datacard can only be removed when the Canlink is switched off! Removing them without
closing the file system can cause corruption. If a card is removed with the unit on it will beep
continuously and instruct the operator to insert the card and power off the system.
2. When powering up the canlink with the datacard in it may take a few seconds to initialise the
card before going to the main screen.
3. Every time the Canlink is powered up a new log file will be created on the card. This will hold
your verification data and will be named for example WEI0404a.log where the numbers are the
day and month, and 'a' corresponds to the first file for that day. The next time the Canlink is
powered on the same day there will be WEI0404b.log on the card. The next day there will be the
WEI0504a.log file etc.
4. The "ERASE" command in the "DATA CARD" screen erases all log files on the card and goes
back to setting the current log file to 'a'.
5. Each log file can be up to 2Mb in size, which is adequate for 1 day of logging (log interval set to
2 seconds) without turning the Canlink off.
6. The memory bar in the main screen shows the log file increasing to 2Mb.
7. It is good practice to not have other files other than Canlink files (log, software, application maps
etc) on the card
8. The canlink automatically detects and displays the size of the datacard.

WINDOWS PLATFORMS
When installing the card reader supplied by Farmscan another drive to read and write to the mmc
card will be added to your system. In all Windows platforms (98, Me, 2000 and XP) data can be
copied from and to the mmc card using "Windows Explorer".
In all the Windows platforms except Windows 2000 the mmc data card can be simply inserted and
removed after copying files to or from the mmc card. Please see the instructions below regarding
removing data cards from the card reader in Windows 2000.
Regarding Windows 2000 & Removing the MMC card from the PC.
When removing mmc cards in Windows 2000 you must follow the procedure below for the canlink
to read the mmc card.
Windows 2000 - Before Removing MMC Card from Card Reader:
1.) In the system tray at the bottom of the screen (where the time is displayed) right click on the data
card remove icon (data card with green arrow).
2.) Click on "Unplug or eject hardware".
3.) The screen below will appear. Click on "USB Storage-MMC" and then click the "Stop" button.
4.) The "Stop a Hardware Device" window will appear, make sure "USB Storage-MMC" is
highlighted and then click the "Stop" button.
5.) A message telling you that it is now safe to remove the mmc card will appear. Click "Ok" and
remove mmc card from card reader.
LOG FILES
The canlink logs data in files. During data logging the canlink copies a log file onto the card. The
log file is named WEI followed by the date (day and month) with the ".log" extension. For example
"WEI2703A.log" is a log file created on the 27th of March. The "A" means that it is the first log file
created on the 27th of March. Other log files created on the same day will be named
"WEI2703B.log, WEI2703C.log etc.
DATA CARD OPERATIONS
The data card can be enabled, disabled and erased. Follow the instructions below.

Use the following guide to troubleshoot problems with the canlink 3500 Grape Yield Monitor. If
the problem can not be remedied contact the Farmscan Service Department on +61 8 9470 1177
(fax: +61 8 9470 2855) or via e-mail: service@farmscan.com.
PROBLEM
POSSIBLE CAUSE / REMEDY
f)
Connect black from loom directly to negative side and red to
positive side of battery. Check there is 12V DC across the red and
black power cables.
Check connections at battery are clean and tight at terminals, try
with engine running.
Check that no other electrical device is connected to the same
power cable – the power cable must be completely independent.
Connect monitor direct to another 12 Volt battery known to be in
good condition.
Run power cable direct to battery. Do not share power with other
devices.
Unable to locate fault – contact nearest dealer.
CANLINK 3500 TURNS ON

SPEED READOUT TOO
FAST OR TOO SLOW
(ONLY APPLICABLE IF
OPTIONAL WHEEL
SENSOR IS FITTED)
a)
If Wheel Sensor connected, recheck "WHEEL" calibration is
measured correctly and entered in metres. Eg. 2.445 metres.
4.
SPEED READOUT JUMPY
(ONLY APPLICABLE IF
OPTIONAL WHEEL
SENSOR IS FITTED)
a)
Make sure magnet is facing sensor correctly as shown in Section 3.2
"Wheel Sensor Installation". (Use of an alternative magnet may
cause problems due to wrong orientation of magnet).
b)
Check that wheel magnet is 10 – 15 mm away from wheel sensor as
they pass. Magnet too close can cause jumpy speed.
If the readout is jumpy, it indicates that the impulses from the wheel
sensor are inconsistent. Check for poor or intermittent connections
to sensor.
Check sensor cable for physical damage especially that it hasn’t
rubbed through on chassis or sharp edges.
If fault can not be found, check “COUNT PULSES” in machine
menu. Drive slowly forward observe the increase in pulses. The
increase should be regular at a fixed speed. If the increase is jumpy,
and wiring is OK, then replace sensor.
If an increase in wheel pulses is seen whilst stationary, then vibration
or interference could be the cause. See Troubleshooting Section 25"
Interference Causes and Remedies".
