2.0 INSTALLATION
2.1 GRAIN LOSS MONITOR INSTALLATION
Mount Monitor in cab for ease of viewing, avoiding direct sunlight on the display (maximum operating temperature 70 degrees Celsius).
Do not mount Monitor directly above or beneath high powered radio transceivers.
Use the mounting bracket and securing knobs supplied to mount the unit in a convenient location. Use height adjustment holes on the monitor mounting bracket to obtain the best possible viewing angle.
Part No: AM-2100
2100 Grain Loss Monitor Manual
2.2 POWER CONNECTION
Do not connect power until all other installation is complete.
The 8 metre POWER CABLE must be connected DIRECT to 12 volt DC vehicle battery terminals.
DO NOT join power cable with any other electrical equipment, the vehicle chassis or run the
Power Cable in close proximity to or alongside radio antenna lead, this may cause interference.
USE cable ties supplied to secure power cable away from risk of damage.
Connection to battery terminals must be clean and tight.
WARNING - Disconnect power cable from battery when arc welding on machinery as damage to the unit may result.

Part No: AM-2100
2100 Grain Loss Monitor Manual
2.3 GRAIN SENSOR PAD INSTALLATION
The standard 1.0 meter (40 inch), 1.3 meter (50 inch) and 1.5 meter (60 inch) Grain Sensor
Pads are designed to be mounted across the full width of the sieve and walker discharge areas.
Consult your nearest Farmscan dealer or authorised service agent for Grain Sensor Pad length recommendations on different machines.
When mounting the grain sensor pads, face rubber side upwards as shown in following diagrams.
Grain sensor pads may be cut down to suit odd machine sizes using a hacksaw or high speed cut-off saw. Rubber ends must be transferred and glued into the cut down section.
Short 20cm (8 inch) grain sensor pads are available for mounting either side of the sieves and walkers in situations where full width sensing is not practical. On rotary (axial flow) machines a 20cm grain sensing pad may be mounted underneath the last (rear) separator grate facing into the direction of rotation.
SIEVE SENSING
The sieve sensing pad should be mounted in the discharge path of the shaking sieve so that lost grain will strike the sensing surface and fall away. Worn paintwork is a good guide to the path of material flow.
5
The standard GRAIN SENSOR MOUNTING BRACKETS supplied may require some modification to suit different machines.
It is important that the grain sensor pad be positioned at approximately 135 degrees away from the shaking sieve so that debris will not accumulate on the sensing surface.
Take care that the shaking sieve will not strike the grain sensor pad.
NOTE: 1.3 and 1.5 metre grain sensor pads should be supported across the entire width to avoid the possibility of fracture under extreme vibration.
In situations where mounting full width grain sensor pad is not practical, 20cm grain sensor pads may be mounted either side of the sieves.
Part No: AM-2100
2100 Grain Loss Monitor Manual 6
WALKER SENSING
The walker sensor pad should be mounted below and just behind the most extreme point of walker travel so that grain lost will strike the sensing area of the grain pad.
Mount the walker grain sensor pad off the inside walls of the hood (rubber facing upwards) at approximately 135 degrees facing away from the walkers so that debris will not accumulate on the sensing surface.
Take care that the moving walkers will not strike the grain sensor pad.
NOTE: 1.3 and 1.5 meter grain sensor pads should be supported across the entire width to avoid the possibility of fracture under extreme vibration.
In situations where mounting full width grain sensor pad is not practical, 20cm grain sensor pads may be mounted either side of the walkers.
ROTOR SENSING
Monitoring of rotor overload is possible by mounting a short 20cm grain sensor pad directly under the last (rear) separator grate facing at approximately 45 degrees into the direction of rotation.
Part No: AM-2100
2100 Grain Loss Monitor Manual
2.4 WHEEL SENSOR INSTALLATION
In the case of self propelled headers, mount the wheel sensor onto one of the ground wheels, or as an alternative, a shaft magnet (Part No. AA-117) may be used on the cross shaft driving the front wheels.
The magnet fitted to the shaft must sweep past the sensor once per rotation as shown, with a clearance of 10 - 15mm.
Do not use substitute magnets.
On P.T.O. headers the wheel sensor should be fitted to one of the front tractor wheels, or one of the header ground wheels.
The magnet, fitted to the wheel must sweep past the sensor once per rotation as shown, with a clearance of 15-20mm. Do not use substitute magnets.
The sensor and magnet must face end to end.
Locate the magnet as near to the hub as possible to gain maximum ground clearance. If unable to bolt magnet through hub, it can be screwed into a 1/2" U.N.F. tapped hole or screwed into the nut brazed onto the hub.
Do not remove sensor from aluminium bracket supplied, damage will result.
If mounted onto a steered wheel be sure the sensor moves on the same axis as the wheel to maintain equal clearance when turning and ensure cable is not pulled tight when turned from lock to lock.
As the sensor is not affected by moisture or mud the main precaution is to protect the sensor and cable from physical damage.
As a precaution, keep the wheel sensor cable away from, aerial leads, engine kill switch cable or wires to electronic clutches and solenoid valves.
Use cable ties supplied to secure sensor cable and connect into Grain loss monitor
Unit.
NOTE: If Grain sensor wiring harness cable will follow same route to cab, do not fully tighten cable ties until both cables are through.

4.0 CALIBRATION PROCEDURE
11
4.1 GENERAL GUIDELINES
The grain loss monitor calculates SPEED and AREA readouts based on wheel and comb width calibration factors, programmed into memory.
All calibration factors must be measured and entered in METERS.
The large selector knob allows Calibration Factors to be displayed.
The UP and DOWN buttons allow you to increase or decrease the calibration factors.
4.2 MEMORY BACK-UP
Whilst the monitor is connected to a 12 Volt battery, all calibration factors and accumulated
Total and Trip areas will remain in memory.
When power is disconnected from the monitor, the internal battery backup takes over, this battery will last for approximately 5 years.
4.3 CALIBRATION WARNING
If calibration factors are lost from memory or corrupted due to outside interference, the grain loss monitor will display the word HELP, and you must re-enter your calibration factors.
1.
2.
4.4 WHEEL SENSOR CALIBRATION
The wheel calibration factor is the distance of forward travel achieved per impulse from the wheel sensor, measured in meters. The calibration procedure must be carried out in normal working conditions for best accuracy.
3.
4.
Align the wheel magnet and sensor.
Mark bottom centre of tyre on which the sensor is fitted and peg ground in corresponding position.
Move slowly forward and stop on exactly 10 tyre rotations. (5 Turns is sufficient on large wheels).
Measure overall distance travelled and divide by 10 (5) to get an average.
eg.
10 TURNS
23.45 ÷ 10
=
=
23.45 METRES
2.345 METRES / TURN
Therefore distance calibration factor = 2.345 meters.
5.
Select WHEEL calibration and use the UP and DOWN buttons to enter wheel calibration factor.
Part No: AM-2100
2100 Grain Loss Monitor Manual 12
4.5 SHAFT SENSOR CALIBRATION (ALTERNATIVE)
3.
4.
1.
2.
Align the shaft magnet and the sensor.
Peg the ground at the base of any tractor or implement wheel.
Move slowly forward and count exactly 10 rotations of the shaft.
Peg the ground again, at the base of the same wheel and measure the distance travelled. Divide the distance travelled by 10 to get an average.
eg.
10 TURNS
23.45 ÷ 10
=
=
23.45 METRES
2.345 METRES / TURN
Therefore distance calibration factor = 2.345 meters.
4.6 WIDTH CALIBRATION
1.
2.
Measure effective comb width in METERS.
You may slightly reduce the width measurement to allow for incomplete comb usage.
Select WIDTH calibration and use UP and DOWN buttons to enter width calibration factor.
4.7 TIME/AREA BASE CALIBRATION
TIME/AREA calibration enables you to select between either grain loss relative to time (loss per second) or grain loss relative to area (loss per hectare).
AREA BASE operation takes ground speed into consideration hence the grain loss reading is a true indication of whether grain loss per hectare is increasing or decreasing (ie grains lost per square metre). The monitor should normally remain in AREA mode. Under 3 KPH the grain loss monitor will automatically cease grain loss indication.
TIME BASE operation means the loss indication purely represents an increase or decrease in grain loss per second and takes no account of changes in the amount of area covered per second (ground speed).
Time base mode may be useful in light crop conditions when harvesting at high speeds or in heavy crop conditions where very low speeds under 3KPH are required.
To select between TIME and AREA BASE, switch function selector to TIME/AREA BASE and hold down the UP button.

2100 Grain Loss Monitor Manual 13
5.0 OPERATION
5.1 GRAIN SENSOR PAD SELECTOR
Under normal operating conditions the grain sensor pad selector switch should remain in the
BOTH position. This displays TOTAL grain lost from both sieves and walker / rotor on the meter scale.
Whenever grain loss becomes excessive either the sieve or walker light will illuminate to indicate where the excessive grain loss is occurring. An audible alarm will sound at the same time.
The operator may then switch to sieve or walker/rotor sensor pad to display it's particular level of loss.
5.2 GRAIN SENSITIVITY
GRAIN SENSITIVITY is used to tune the monitor to various sound frequencies generated by the grain hitting the grain sensor pad surface.
The operator is able to adjust the grain sensitivity to achieve maximum needle response for specific grain types.
The heavier the grain the lower the setting and the lighter the grain the higher the setting, as indicated on the grain sensitivity scale (ie. the setting where the reading reads highest).
Some suggested grain sensitivity settings are;
LUPINS / PEAS
WHEAT / RICE
OATS / BARLEY
SET
SET
SET
1 - 3
4 - 6
7 - 9
Once adjusted, there is no need to change the setting until harvesting a different variety of grain.
NOTE: If you have difficulty getting a response, change TIME/AREA BASE calibration to TIME
BASE mode (P - 1) and try again.
5.3 LOSS CALIBRATION ADJUSTMENT
LOSS CALIBRATION allows you to adjust the needle reading to stay within the GREEN band when the machine is operating at an acceptable loss situation.
Once the needle moves into the RED band the alarm will sound.
Correct adjustment of the loss calibration knob should be done by trial and error comparing the needle reading with actual grain loss on the ground.
Part No: AM-2100
2100 Grain Loss Monitor Manual 14
5.4 SET-UP PROCEDURE
1.
2.
3.
Make sure TIME/AREA BASE calibration is set to AREA BASE (P - 2).
Use screw driver supplied to adjust TRIM CONTROL (located between loss calibration and grain sensitivity knob) in anticlockwise direction at least 20 turns or until faint clicking sound is heard.
Select to read Sieve Sensor Only and commence harvesting, then adjust loss calibration knob until needle reads towards top of GREEN band.
4.
a) b)
5.
Without touching loss calibration knob, switch to walker/rotor sensor and watch needle response.
If needle goes into RED band adjust TRIM CONTROL slowly clockwise until alarm stops and needle reads at the same point as the SIEVE reading.
If needle stays well within the GREEN band do not adjust the TRIM CONTROL, it just means there is insufficient loss over the walkers to activate the needle.
Return the pad selector switch to BOTH and if the needle moves into the RED band, adjust the loss calibration knob back till the needle stays in the GREEN band.
Once this balance is achieved, the loss calibration knob will provide adequate overall adjustment for day to day variations.
5.5 RUN / HOLD HECTARES
This button may be pressed at any time to stop or start the area function on headlands or when travelling to unload.
When in HOLD mode the letter H will appear at the left of the main readout together with a short reminder beep every twenty seconds. Press the RUN/HOLD button again to start the area updating.
Part No: AM-2100
2100 Grain Loss Monitor Manual 15
5.6 SPEED / AREA READOUT
The function selector knob enables on the go display of, SPEED, TOTAL AREA and AREA PER
HOUR readouts.
HECTARES PER HOUR - Readout is only active when harvesting as an indication of progress rate.
SPEED - Displays working speed to 1/10th KPH.
TRIP AND TOTAL HECTARES - The TOTAL and TRIP HECTARE readouts operate in a similar way to your car odometer except the grain loss monitor has nine trip area memories. Area will display in hundredths of hectare up to 99.99 HA, then in tenths up to 999.9 HA then in whole hectares up to 9999 HA.
Prior to harvest, the TOTAL HECTARE memory may be reset to zero, which will simultaneously cause all TRIP HECTARE memories to clear.
When harvesting, area worked will accumulate into the TOTAL HECTARE memory and one of the nine TRIP memories selected. eg TRIP 1
The trip memory currently selected may be reset at any time without affecting the overall accumulated total or other trip totals.
Once the next available trip memory is selected eg. TRIP 2, for example when entering a new paddock, the previous current trip total (TRIP 1) will be locked into memory for reviewing at any time.
NOTE: Once a new trip memory is activated, additional area can not be stored into previously active trip memory.
TO RESET TOTAL & TRIPS, select TOTAL HECTARES and hold RESET button until display zeros, this will simultaneously cancel ALL accumulated trip totals.
TO RESET CURRENT TRIP, select TRIP HECTARE memory and hold RESET button until display zeros.
NEXT TRIP, to activate the next available trip memory, select TRIP HECTARES and press both the UP and DOWN buttons together. The next trip number will be indicated to the left of the main readout (1-9).
REVIEW PAST TRIP to review past trip totals locked into memory, hold down the UP key.
NOTE: To Stop/Start AREA meter automatically, optional Mechanical or Electronic standby kits are available.
OPTIONAL: 1036 ELECTRONIC STANDBY connects to any existing switch that is turned on or off when the machine is engaged (eg. Reel Engage) to stop/start meter.
1037 MECHANICAL STANDBY connects to any mechanical device that is moved from one position to another (eg. engage lever) to stop/start meter.
