1.0 INTRODUCTION

The Farmscan canlink 3000 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 and GPS information.

The canlink 3000’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 3000 Grape Yield monitor features: automatic hold functions, 24 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 3000 platform upon which the grape yield monitor operates has been designed to grow as new applications are integrated. The versatility of the canlink 3000 allows it to be reprogrammed in the field using a mmc card. Already in place, the 3000 has several yield functions, variable rate for up to four products, spray control and soil sampling functions.

NOTE: GPS 1Hz!We recommend that a 1Hz GPS is used, outputting the GGA and RMC strings. Do not use a 5Hz GPS.

canlink 3000 Grape Yield Monitor : LOAD CELLS EXPLAINED 5



3.0 LOAD CELLS EXPLAINED

GeneralThe 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 InformationThe 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 DownThese 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 CellsThe 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 ResolutionThe 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%).

canlink 3000 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 WiringInternally, 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 neverweld on or near the weigh platform where load cells have been installed!

! ImportantNever weld on or near the weigh platform where load cells have been installed!!!

canlink 3000 Grape Yield Monitor : INSTALLATION 7



4.0 INSTALLATIONThe 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 3000 MOUNTING BRACKET INSTALLATION

Adhere the two rubber adhesive washers (HG-005) provided in the kit onto the inside of the canlink 3000’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 undrivenground 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.

WHEEL SENSOR INSTALLATION PROCEDURE

5 – 10 mmclearance




1. 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.

2. 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.

3. The sensor must be rigidly bolted to an existing structure, ideally in a protected position to face the magnet as shown.

4. 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 INSTALLATIONThe 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.

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 INSTALLATIONFour 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.

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 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.

• Carefully cut away this 600mm section with an angle grinder.




Step 2Mark holes for bolting load cell frame to trayBoth 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. NoteHoles 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 3Before 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 4Bolt 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 5Load Cell Cable ExitTo 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 6Adjust Load Cell Bearing Height 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.

• 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 INSTALLATIONMount 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.

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 INSTALLATIONThis 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 3000 2. Proximity switch connection to load cell junction box3. Load cell junction box connection to cab loom 4. Connection to power

See page 19 for a diagram of the full system connection scheme.

STARTConnect the cab loom (AC-3000GRAPE/T) to the port on the canlink 3000, labelled “LOOM CONNECTION”.

CONNECTION TO LOAD CELL JUNCTION BOXConnect 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.

WIRING IF "ATOD" READING DIMINSHES WHEN WEIGHT APPLIED:If the “ATOD” reading (“SENSORS” screen, press “CAL”, highlight “SENSORS” using arrow keys and press “CAL” to enter) diminishes when weight is applied to the belt, then swapping the green and white wires as soldered into the 4 pin female plug will fix this. See the diagram below.

LOAD CELL CABLE DESCRIPTIONRed +5VBlack -5VWhite +Green -Braid EARTH

Note: Silver braid not connected.




CONNECTION TO GPSConnect the GPS unit to the canlink 3000 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 POWERConnect 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 3000.

Follow the guidelines given below when connecting to power.

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 below for typical battery connection schemes.




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 3000 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

“ATOD” reading to around 100. Turn anticlockwise to increase and turn clockwise to decrease the “ATOD” reading, see below.

Apply slight weight to the platform and make sure the “ATOD” reading goes up. If not refer to the sub section “WIRING IF LOAD CELLS MOUNTED UPSIDE DOWN“ in section 4.4.

Proceed to the “WEIGH SCALE” calibration procedure in section 6.5 to calibrate the yield monitor.

In the calibration menu screen and in other calibration screens the arrows allow the operator to move around the screen and to change configuration values.

5.8 SOFTKEYS (8)The softkeys (8) are situated around the edge of the display. There are ten softkeys, which correspond to a function displayed on the screen that may also change from screen to screen.

In the main screen the vertical softkeys are used to activate tags and select the tags to be activated. There are 12 tags in total.

If the softkey is inoperable within a particular display there will be no adjacent icon on the screen.




MAIN SCREEN

The main screen of the canlink 3000 Grape Yield Monitor is divided into seven areas as follows:

1. Yield 2. Trip 3. Total 4. Speed5. Messages 6. Tags7. GPS/Time

Quantities appearing in the main screen can be displayed in metric or US units. See section “5.8 OPTIONS” to toggle the display to metric or US units.

5.9 YIELD The Yield section provides the operator with the following information:-

1. YIELD : The rate at which the product is being harvested in tonnes/hectare or

tons/acre.

2. LOAD : The weight harvested in tonnes (metric) or tons (Imperial) since it was lastreset.

There is an alarm associated with the load value. It can be used to alert the operator to when a set weight has been harvested.

To reset the load value press the “RESET” key and a confirmation message: “RESET?” will then appear in the display section below the “LOAD” value. Press the “RESET” key again to confirm. Press any other key to cancel.




5.10 TRIP

The “TRIP” section allows the operator to monitor both the area covered and the weight of product harvested for a particular sub area. The trip number/name displayed is the trip under which all records are currently being accumulated. There are 24 available trips.

To reset the trip go to the records screen (“RECORDS” button) and press the “RESET” key twice. The records function is further explained in the “RECORDS” section.

5.11 TOTAL

The “TOTAL” section shows the accumulated total area covered and the accumulated total weight of product harvested since the total was last reset. To reset the total go to the records screen (“RECORD” button) and press the soft key below “<PREV” which is displayed on the bottom right hand corner. The total screen will now be displayed. Press the “RESET” key twice.

5.12 SPEED

CARD ERROR An error occurred while the monitor was trying to read or write to the card. Check that the card is inserted correctly.

NO DIFFERENTI An alarm message that will appear if a differential signal has been present and it is missing.

5.14 TAGS

The vertical softkeys allow the operator to choose from 12 different tags that can be selected at any time during harvesting. This will store the tag name and the GPS coordinates on the data card for future reference.

A short press of a tag softkey will result in a point being logged with that tag. The tag will remain highlighted for a second. A long press (held for 2 seconds) will result in continuous tagging. The tag will then stay highlighted until it is pressed again.




The operator can move between three sets of four tags using the “PREV” and NEXT” softkeys at the bottom of the main screen. The tags are labelled by default as follows: TAG 1, TAG 2, TAG 3, TAG 4, TAG 5, TAG 6 and so on to TAG 12.

For convenience all 12 tags can be relabelled. To change a tag label refer to section 5.8 “TAGS” in the next chapter.

5.15 GPS/TIME

The “GPS/TIME” window displays GPS information being received by the monitor. The current time is displayed in the right of the window.

If no GPS data is being received the time will be displayed.

When the monitor is receiving a GPS signal coordinates will be displayed. When a differential GPS signal is received the character ‘D’ will proceed the coordinates.

IMPORTANT!• GPS output rate must be set to 1Hz! Do not use a 5Hz GPS.• GPS must output the GGA and RMC strings. This is sufficient for data logging and

operation of the monitor.




RECORDS SCREEN

The canlink 3000 is capable of storing complete records for 24 trips. The records screen is shown below.

The operator may press the “RECORDS” key at any time to display the trip record for any of the 24 trips. The trip record will be displayed for the currently active trip, which is the same trip displayed in the trip section of the main screen. Trip records for any of the other remaining 23 trips can be viewed using the “< PREV” and “NEXT>” softkeys. Particular trips are activated for data accumulation using the “SELECT” softkey, functions of the softkeys are described in more detail below.

Each Trip Record screen shows the following information:-

1. Trip name 2. Weight3. Area 4. Average

TRIP NAME: This is a number between 1 and 24 or . Each field should be recorded under a new trip even though the field or fields may contain the same crop.

WEIGHT: The weight harvested in tonnes or tons in the trip.

AREA: The area in hectares or acres harvested to date under the selected trip.

AVERAGE: The average work rate in tonnes per hectare or tons per acre for the selected trip.




VIEWING AND ACTIVATING DIFFERENT TRIPS

Records for different trips can be viewed using the “< PREV” or “NEXT >” softkeys, and different trips can be activated for data accumulation using the “SELECT” softkey. The function of the “< PREV”, “NEXT >” and “SELECT” softkeys are described below.

< PREV: The “< PREV” softkey will display the previous trip record unless the first trip record is currently displayed, then the total record will be displayed

NEXT >: The “NEXT >” softkey will display the next trip record unless the last trip record is currently displayed.

SELECT: The “SELECT” softkey is used to activate different trips for data accumulation. To activate a trip to appear in the main screen, use the “<PREV” and “NEXT>” softkeys to find the trip and then press the “SELECT” softkey to select the trip. Press the “EXIT” softkey to activate the trip, the selected trip will then appear in the trip section of the main screen.

EXIT: The “EXIT” softkey will return the operator to the main screen.

RESETTING TRIPS

To reset trip information press the “RESET” key and a confirmation message will appear. Press the “RESET” key again to confirm. Press any other key to cancel.

canlink 3000 Grape Yield Monitor : CALIBRATION 31



6.0 CALIBRATION

The canlink 3000 is calibrated and configured using 9 menu items displayed in the calibration menu screen, shown below. Under each of the menu items are special screens through which the monitor’s calibration and configuration settings can be displayed and changed.

! BEFORE STARTING CALIBRATIONThe monitor can be calibrated in either metric or US units. Before calibrating, the system of units must be set (See “6.6 OPTIONS”). Quantities will be displayed in the units set for calibration.

DISPLAYING THE CALIBRATION MENU SCREENTo display the calibration screen press the “CAL” key located on the right of the monitor. The “CAL” key can be pressed at any time from any screen to display the calibration menu screen.

MAKING A SELECTIONTo make a selection use the arrow keys and/or the softkeys to move the highlighted box about the screen. When the correct box is highlighted press the “CAL” key to display the selected calibration function.

A detailed discussion of the contents and functions of each of the menu items is presented in the following sections. The name of each section heading is identical to the name of the menu items.




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 LEVELThis 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”.

ZEROSets 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.




DIVIDERFor 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 CALIBRATION1. 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 CALIBRATION1. 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.

WIDTHEnter the width of the machine’s harvesting path (swath) in metres or inches.

WHEEL FACTORThe “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.

DISTANCEThe 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 PULSEThe “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.




PROCEDURE TO CALCULATE WHEEL FACTOR:

To determine the wheel factor follow the procedure below:

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 COUNT WHEEL PULSE 14

NOTE: If you miss a pulse go forward and stop on the next pulse, Do Not Reverse!

6. Measure the distance travelled from the starting peg to the centre of the same tyre

7. Enter the measured distance into the “DISTANCE” item (Do not reset the pulse count!) by pressing the corresponding softkey and using the up and down arrows see diagram below.

8. Press the “UPDATE” softkey at the bottom left of the display for the monitor to calculate the new wheel factor.

NOTE:• Wheel pulses can be reset by pushing the “RESET” key.• The “DISTANCE” value is reset to a default of 100 m or 100 yards.




6.3 DISPLAY

The canlink 3000 provides the operator with control over display contrast and backlighting. Selecting “DISPLAY” on the calibration menu screen will bring up the display screen as shown below.

CONTRASTThe 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.

DISPLAY ILLUMINATIONDisplay illumination refers to the brightness of the LCD backlighting. This can be changed between two settings: HI, and OFF. The display illumination is set to either of the two settings by pressing the softkey adjacent to it. At night time the LCD backlight may be too bright and can be turned off.

! GLASSES WITH POLARISED LENSESThe canlink 3000 display is not suitable for viewing using glasses with polarised lens.




DISPLAY INVERTThe “DISPLAY INVERT” item toggles the display invert option on and off. When off all character pixels are blackened and all the background pixels are illuminated. When on, background pixels are blackened and all character pixels are illuminated.

SHOW TEST SCREENPressing the softkey adjacent to the show test screen item displays the “MASS 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.




6.4 TRIP

Selecting "TRIP" from the calibration menu brings up the “TRIP NAME EDIT” screen shown below. This screen allows the operator to change the names of the 24 available trips.

The 24 trips are displayed using a total of six screens. Each screen contains two identical columns of four trips. The right-hand column of trip names can be changed while the trip names in the left-hand column can not. This gives the operator an ordered reference for edited trip names.

EDITING A TRIP NAMEThe “< PREV”, “NEXT >”, “SPACE”, “0-9”, “A-Z” and “EXIT” softkeys are used to change the name of a trip.

To edit a trip name follow the steps below:

1. Press the NEXT > softkey to find the trip number to be edited.

2. Press one of the four softkeys pointing to the row on which the trip name is located.

3. A cursor will appear highlighting the first character of the trip name in the right-hand column.

4. Position the cursor over the character to be changed using the left and right arrow keys.

5. Press one of the softkeys adjacent to either of the three icons: “SPACE”, “0-9” or “A-Z” located on the bottom of the display.

* Pressing the “A-Z” softkey inserts a character of the alphabet.

* Pressing the “0-9” softkey inserts a number to be inserted.

* Pressing the “SPACE” softkey inserts a space between characters or deletes a character.




6. Use the up or down arrows to select the letter or number wished to be inserted or changed. Then move to a new row or press the “EXIT” or “BACK” softkeys to save the changes.

NOTE:• While editing, holding down either the up or down arrow keys for one second will cause

the highlighted character to scroll through the available letters or numbers.

6.5 SENSOR When “SENSOR” is selected from the calibration menu the screen below is brought up. With this screen the operator can calibrate the yield sensor and select the units being displayed.

ROLL CORRECTIONThis is a percentage weight per degree factor, used to correct the load value when the harvester is not on level ground and the junction box is tilted as shown in the diagram below.

PITCH CORRECTIONThis is a percentage weight per degree factor, used to correct the load value when the harvester is not level ground and the junction box is titled as shown in the diagram on the next page.




PROCEDURE TO DETERMINE PITCH AND ROLL CORRECTIONSThe 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 SENSORThe 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 SCALEIs 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.

EXAMPLE:actual weight : 10 kgraw value: 1234weigh scale: 10 ÷ 1234 = 0.0081

NOTE :Make sure the system has been zeroed first.




6.6 OPTIONS

When “OPTIONS” is selected from the calibration menu the screen below is brought up. With this screen the operator can select the units being displayed and activate some useful hold functions.

LOAD ALARMEnter a weight in tonnes or tons and when this weight is reached the monitor will issue the audible alarm “LOAD FULL”.

SPEED HOLDEnter a speed in km/h or mi/h and if the harvester’s speed falls below the “HOLD SPEED” the monitor will be put on hold.

BELT HOLDEnabling the belt hold function will put the monitor on hold when the belt is stopped.

UNITSQuantities can either be displayed in metric or US units. Highlight the “UNITS” item and use the up and down arrow keys to select the system of units to be used.

NOTE:• Quantities entered for calibration must be entered in the same units as the monitor is

displaying.

COMPEnables a second load cell installation (not supplied) to work as a compensation sensor. Where the weight measured by the compensation sensor is subtracted from the weight measured by the yield sensor. This is only required for machines harvesting crop such as carrots which are harvested carrying a lot of debris, dirt, mud etc.

“COMP” must be left “DISABLED” unless a compensation load cell installation is installed (not supplied and necessary for grape yield).




6.7 CLOCK/GPS

The time can be set or changed, the GPS can be enabled/disabled and the communications baud rate with the GPS can also be set. The monitor supports baud rates of 1200, 2400, 4800, 9600 and 19200 bps.

CLOCK/DATETo set, use the “LEFT” and “RIGHT” arrow keys to highlight the digit to be changed, then use the up and down arrow keys to change the highlighted digit. To toggle between time and date, use the top left softkey.

GMT OFFSETPressing 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.

GPSPressing 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.

NOTE: GPS AS A SPEED SENSOR The canlink 3000 uses the GGA string for position and the RMC string for speed, setting wheel size to zero will allow the canlink to use the RMC string for speed input thus eliminating the need for a wheel sensor.

The canlink must also receive the RMC string from the GPS to log yield data for yield maps.

IMPORTANT!• GPS output rate must be 1Hz! Do not use the 5Hz setting!• GPS must output the GGA and RMC strings. These strings are sufficient for data logging.




6.8 TAGS

Selecting “TAGS” from the calibration menu screen brings up a screen displaying all twelve tag labels arranged in columns as shown below. This screen allows the operator to edit the default tag labels and create new tag labels as many times as required.

EDITING TAG LABELSTag labels are edited in the same way as are trip names. See section “4.5 TRIP” “EDITING TRIP NAMES”.

6.9 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 CARD1. 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 PLATFORMSWhen 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 FILESThe 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 OPERATIONSThe data card can be enabled, disabled and erased. Follow the instructions below.

ENABLE/DISABLE DATA CARD1. Select "DATA CARD" from calibration menu and press ‘CAL’.2. Press �"DATA CARD" key to highlight the data card's capacity or the word "DISABLED".3. Use the RHS � and � arrow keys to toggle between data card capacity and "DISABLED".

Use the following guide to troubleshoot problems with the canlink 3000 Grape Yield Monitor. Ifthe problem can not be remedied contact the Farmscan Service Department on +61 8 9470 1177 (fax: +61 8 9470 2855) or via e-mail: [email protected].

PROBLEM POSSIBLE CAUSE / REMEDY1. CANLINK 3000 DOES NOT

TURN ON.a) 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.

b) Check connections at battery are clean and tight at terminals, try with engine running.

c) Check that no other electrical device is connected to the same power cable – the power cable must be completely independent.

d) Connect monitor direct to another 12 Volt battery known to be in good condition.

e) Run power cable direct to battery. Do not share power with other devices.

f) Unable to locate fault – contact nearest dealer.

2. CANLINK 3000 TURNS ON BUT NO DISPLAY ON SCREEN.

a)

b)

Use the left and right arrow keys to adjust the contrast.

If no response, switch the unit off and on and press the right arrow for 5 to 10 seconds.

3. 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.

c) 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.

d) 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.

e) 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".




PROBLEM POSSIBLE CAUSE / REMEDY5. SPEED READOUT STAYS AT

ZEROa) If using GPS for the speed sensor, check that the “WHEEL”

calibration is set to zero

b) If using GPS for the speed sensor, check that you are receiving the RMC GPS string. See “SHOW TEST SCREEN”.

6. WHEEL SENSOR TEST PROCEDURE

TEST WHEEL SENSOR WITH A MULTIMETER ONLY.

a) Disconnect wheel sensor from cable.

b) Switch multimeter "ON: and select "OHMS" scale.

c) Touch test probes together and meter should display “0" OHMS resistance.

d) Connect test probes to wheel sensor pins. If meter goes immediately to zero without magnet, then sensor is short circuit (faulty). Place wheel magnet in front of sensor, meter should go straight to zero. If meter fails to change, then sensor is open circuit. (Faulty)

7. TOTAL AND TRIP AREA INCORRECT OR NOT RECORDING

a) Check speed readout is correct and steady.

b) Check that the width factor in the “MACHINE MENU” is correct.8. ALARM MESSAGE:

“SENSOR FAIL”a) Monitor sensor communications problem. Check cab loom and

extension cable connections to yield sensor, especially the blue and green/yellow wires in the cable.

9. YIELD SENSOR INACCURATE

a) Check “WEIGH SCALE” factor and repeat “WEIGH SCALE” sensor calibration procedure in section 5.4. Check pitch and roll correction factor. Factor should be small. If factor is large, redetermine pitch and roll correction factor, see section 5.4.

b) Review “DIVIDER” setting.

c) Check that load cell is securely mounted.

d) Check that proximity switch is mounted correctly, within 4mm or 0.17” of metal teeth on cog. Also check alignment using diagnostic screen see section 6.3 of this manual.

e) Check that the pitch and roll sensor is secure and is fixed relative to the load cells.




PROBLEM POSSIBLE CAUSE / REMEDY10. LOAD CELL LEVEL

READING NEGATIVEConnected one load cell at a time. If ATOD reading decreases when weight is applied then the load cell has been mounted upside down and the green and white wires from the load cell need to be swapped. See section 4.4 of manual.

11. MONITOR GOES ON HOLD WHEN NOT DESIRED.

a) Decrease or disable the hold speed function.

12. DATA CARD INSERTED BUT ALARMS “MC CARD FULL” OR “CARD ERROR” ARE DISPLAYED.
