IMPORTANT INFORMATION for your Model 870S

This instrument (Model 870S) is calibrated for cured hay only.

Not for uncured hay or silage.

Conductivity meters will read differently, which will require the operator to gain experience comparing the 870S output to past methods to maximise the usefulness of the model 870S instrument.

Please Note:

With regard to the possibility of spontaneous combustion of hay, we can not tell you at what moisture you can safely bale hay at. The safe baling moisture level is dependent on many other factors including but not limited to the water soluble carbohydrate levels, microbial count, type and variety of plant, prevailing weather conditions and storage conditions.

For information on determining the levels of the various factors that lead to spontaneous combustion of hay we suggest you contact you fodder peak body who should be able to assist you.

The following information should be maintained in the event that you require support from the manufacturer.

Introduction

1.1

System Components

The Gazeeka Model 870S moisture monitor consist of the following components:



Transmit Antenna - An active transmitting antenna containing microwave electronics to (1) generate and transmit the beam of microwave energy into the bale, and (2) receive and analyse the signal retuned from the receive antenna.



Receive Antenna - A passive receiving antenna on the opposite side of the bale (ie. opposite the transmit antenna) which collects the microwave energy which has not been absorbed by the bale. The microwave antennae have been designed to optimise the moisture measurements in the baled fodder.



Microwave Cable - A microwave cable (run inside a flexible steel conduit) which carries the collected microwave signal from the receiving antenna back to the electronics in the transmitting antenna for comparison with the originally transmitted signal.

The microwave cable between the two antennae is an important part of the overall system and must be installed and maintained properly if optimal performance is to be achieved. There is

more on this subject in the installation and maintenance chapters.



Terminal (LCD Display/Keypad) – A liquid crystal display (LCD) unit with a keypad mounted in the driver’s cabin to enable control and measurement feedback.



Antenna Support Frames – Used to mount the antennas onto the rear of the baler.



Baler Cable (Interface Cable) - A cable to connect the transmit antenna to the

Terminal in the tractor cabin. The power for the transmit antenna comes directly from the tractor via this cable.



Marking Spray System – A paint spray marking system that is capable of automatically marking bales for easy identification at the pickup stage.

How it Works

The Gazeeka Model 870S instrument uses microwave techniques to measure the moisture content of the hay in the bale as it emerges from the baler.

Gazeeka instruments use techniques that are based on sound scientific principles, which have been proven in the laboratory and verified in the field.

The instrument measures the speed of the microwaves and the amount of microwave energy absorbed through the bale of hay. The speed of microwaves through air is very close to the speed of light through space, and the speed of microwaves through dry hay is a little slower than through air. However, the speed of microwaves in water is considerably slower than that in dry hay. The difference in this speed is attributed to a value known as the dielectric constant (or sometimes called relative permittivity).

The dielectric constant for air is close to 1, for dry fibrous material it is closer to 2 while for pure water it is approximately 80. Similarly, the amount of microwave energy absorbed in air is less than dry hay and in dry hay is much less than in water. Thus if measured correctly, these measurements can be a very sensitive method of measuring moisture in the bale of hay.

The calibration of the Gazeeka moisture monitor was carried out without removing variable factors such as hay temperature, bale density and the way the bale was pressed to try and ensure that typical variations in these types of variables are within the precision parameters required in a reliable, real time, on-line hay moisture measurement system.

Microwaves can "bounce" off stationary or moving metal objects and interfere with measurements, so the Gazeeka Model 870S System uses both hardware and software techniques to minimise the effect that these sources of "noise" may have on the operation of the instrument. Further information on how to obtain the best performance from the Gazeeka Model 870S moisture monitor can be found in the installation section.

All of the microwave signals are generated using crystal locked frequency synthesisers. This means that there is no maintenance requirement to check operating frequencies for optimum moisture measurement performance.

As a bale moves into the microwave beam, the system detects the change in microwave signal and determines a bale is present. The system then looks for small changes in the microwave signal to indicate that the bale is moving within a reasonable time allowance for a plunger stroke (if not it determines the bale has stopped). Then once the system determines that the bale is far enough past the microwave beam so that it can reasonably be expected that the entire detected microwave signal has traveled through the bale (and not some of the signal around the end of the bale) it starts to convert the microwave readings to a moisture content.

In simple terms there are only three things that are critical to obtain a good moisture measurement, (assuming the microwaves are being measured correctly). These are a good air path reading, the bale width set properly, and the correct equation for the type of hay being baled is selected. The fist two items are close to "set and forget" once these are set they should not change from year to year unless the baler is changed or parts of the microwave system are replaced or moved.

To ensure that your Gazeeka Model 870S instrument remains compliant in terms of electromagnetic emissions and electromagnetic susceptibility, the instructions and procedures in this manual are recommended to be followed.

1.3

Using the Moisture Data provided by your Gazeeka Analyser.

Understanding the limitations of the readings.

Some of these points are reasonably obvious, but are documented here to clear up any misunderstanding :



Moisture Distribution - The 870S antennae are approximately 8 inches (200mm) wide. The 870S is measuring an average

1 moisture through the bale in a volume approximately as wide and as high as the antenna dimensions. The 870S calculates a moisture value approximately 10 times a second (about once every

100 milli seconds). Within each of these 100 milli second readings, thousands of microwave readings are made and many microwave readings are averaged to get the best moisture reading. If the moisture distribution along the bale is varying wildly (approximately 0.5%) within this short reading time as the bale moves by, then the output from the analyser may be unpredictable.



Leading Bale - The trigger mechanism to start the readings is set up so that the

870S starts its microwave readings approximately 1 foot (300mm) in from the leading edge of the first bale. In normal situations this will only apply to the first bale out and the successive bales will generally abut the preceding bale with no gap between them. Like any electromagnetic signal the microwave signal will always take the easy path if it is available, so, if the readings are taken too close to the ends of the bale, the signal may go around the bale rather than through it, or some other unpredictable "end effects" may occur.



Process Control Loop - If you are using the output of the 870S in a process control loop (for example adding preservative to a bale), the instantaneous moisture readings may vary too much for the process control system to track properly (over compensating or "hunting" may occur). In this case, use the time smoothed output

(you can edit the time constant used) as the input into you process control loop.



Moisture Additions - Moisture additions which are poorly distributed throughout the bale are likely to cause the 870S to give unpredictable results which may be higher or lower than the true average. There are a number reasons why this may occur.

Just one reason why this may occur is if the readings that the 870S is taking as the bale moves along synchronize with either the low moisture bands or the high moisture bands, or an uneven combination of both which will cause a biased reading.



Fodder Temperature -The temperature of the material under test should also be consistent within +/- 5 degrees Celsius (+/- 10 degrees Fahrenheit) to ensure that any bias taken out during calibration remains constant. The dielectric constant for moisture changes with temperature, however these changes are small compared to when the temperature is close to or beyond the freezing point or boiling point of the moisture at which temperatures the instrument will not provide reasonable readings.

This instrument cannot measure moisture that is frozen or very close to frozen. Performance of conductivity probes is also affected by the freezing of the moisture.



Microwave Distortions – Sometimes the leading or trailing edge of a bale or severe layering of high moisture sections within the bale can lead to microwave alternative paths and or resonance effects. Your Model 870S has been programmed to detect most (if not all) of these type of distortions which may effect the accuracy of the moisture reading. In these cases, the last reasonable moisture reading is held and the operator is alerted that an error has occurred. These errors are very transient and usually disappear within seconds.

870S V13p00 8



Bale gaps – Occasionally, the gap between two bales is very close to a multiple of the microwave wavelength (typically about 120mm - 5 inches) and extra signal energy is absorbed. This leads to a one off high moisture reading at the end of a bale. If this happens too often the problem can easily be resolved by shortening or lengthening the tail gate chains a small amount to change the gap between bales making smaller or larger. Please note, this problem is extremely rare.



Hay Additives – Some hay additives are extremely conductive (especially

propionic acid which unlike most additives, requires you to increase the dose rate as the moisture content increases, leading to very high does rates at high

moistures.). We have found that for all the typical additives on the market, the recommended dose rate has little or no material effect on the performance of the

Gazeeka 870S. However, if you over dose this may cause the conductivity to rise up to a point where you need to consider its effect on the moisture reading. High conductivity in hay caused by additives will affect the microwave readings as well as the conductivity readings, but it will affect the conductivity readings by much more.

Indemnity 1

International Stock Foods. (the company which sells the Gazeeka brand) shall not be responsible for any consequential damage cause by the use of the analyzer.

The Gazeeka instrument is an extra tool that should assist the operator in assessing and controlling the operational status of the baling operation.

The values provided by the instrument should not be used to determine

contractual or custody transfer issues. These issues should be determined by statistically representative sampling and laboratory assays carried out to national or international standards.

1.4

Standard Outputs

The standard outputs from the Gazeeka 870S analyser are as follows:



Instantaneous Moisture output - This gives you the average moisture reading over a preset analysis time (typically 5 seconds).



Peak Moisture output - This gives you the maximum moisture reading over a preset number of instantaneous readings. This is typically 12 readings (12 x 5 = 60 seconds of analysis time).



Smoothed Moisture Output (average moisture reading) - This gives a time smoothed output of the moisture from a number of Instantaneous readings. For example, if the analysis time is set to 5 seconds and the smoothing time constant is set to 120 seconds, then this output will give the average of the last 24 readings

(120 / 5 = 24 ). Note that this time is the time spent analysing, not the real time on a clock.

This description of the smoothed moisture output is a slight simplification of what actually happens. For the technical person, the smoothing time is the time based coefficient in a moving exponential smoothing algorithm.

2.1

General

An installation which is properly carried out and takes into account all of the issues raised in this manual will minimise any risk that the moisture reading obtained from the Gazeeka Model 870S moisture monitor will be erroneous.

Other than the specific issues raised in this chapter, the general issues of good installation practice and common sense still apply if the best results are to be obtained.

General items not supplied by Gazeeka.

Gazeeka's normal supply does not include the following:



Electrical Noise filters or isolation that may be required on the vehicle.



Lightening protection.

Indemnity 2

The Gazeeka analyser has been designed to withstand reasonable levels of normal electrical "noise"; however, warranty does not cover any damage cause by electrical noise which may include electrostatic discharge, lightening strike, load dumping

(disconnecting the battery whilst the alternator is still charging), welding etc. Gazeeka shall not be responsible for any consequential damage cause by the use of the analyser.

Sources of Microwave Interference.

The Gazeeka Model 870S moisture monitor uses low levels of microwave radiation.

External sources of microwave radiation can affect the readings, as can the reflected signals from nearby microwave signal reflectors.

There are many sources of microwave signals around in today's environment. Burglar alarms, data transmission systems, and microwave ovens, "Bluetooth" communications systems, just to name a few. Any Bluetooth or similar 2.4 GHz communication system should be kept at least 10 yards away from the Gazeeka

870S system. This may include cellular phones which are Bluetooth enabled.

A large percentage of the human body consists of water. Anyone in the vicinity of the microwave measuring beam is likely to affect the results. For best results, no one should be within a yard of the microwave beam which travels between the antennae.

This includes a yard behind each antenna as well as "around" the beam. Please note that this issue is not related to work place safety issues, as the microwave levels are so low; however, as always, it is best to minimise any unnecessary exposure.

870S V13p00 10



Owner's Manual & Quick Reference Card

1. Unpack the box of Gazeeka components. Note that one antenna has the connector which attaches to the cable that goes through the baler to the tractor.

This antenna is the active (or transmitting) antenna and must be mounted on the

Left Hand Side of the baler as viewed from the back.

2. Carry out this installation with the baler tailgate down.

3. Mark both sides of the rear side of the baler frame at the midpoint of the bale height (18" for a 3' bale). Place the template up against the baler frame with the hole in the middle of the template in line with the bale centre line you marked.

Now you may have to move the template out a little to make sure it clears any weld fillets and you may have to move it up a little as some balers have a bolt on the front side of the baler frame where you would be drilling the holes for the microwave antenna brackets.

4. Mark the hole centers with a center punch. Repeat this for both sides of the baler.

5. Using a setsquare or other suitable system, measure and center punch the positions of the holes on the front side of the baler frame. You can mark one hole, and then use the template to determine the second hole position.

6. Some balers have electrical wiring going through the rear baler frame to which you are attaching the microwave antenna. Please make sure you do not damage this wiring in the process of drilling the holes or mounting the antennas.

7. Drill these holes using a pilot drill say 1/8". Then drill out with a 3/8 clearance drill

(say 13/32" or 27/64").

8. Use the 2' x 2" x 1/4" square washers provided on the opposite side to the brackets to prevent crushing in the square hollow section of the baler frame.

9. Secure the two top brackets in place using a spirit level to get them horizontal.

Tighten these bolts up. Note there are two types of brackets so make sure you use the appropriate bracket as per the photo below. The flange of the brackets will be at the top for the top bracket and at the bottom for the bottom bracket. This is done to minimize the chances of interference to the microwave signal.

870S V13p00 11

10. Secure the bottom two brackets in place just tight enough to be able to move them around by hand. All of the bracket bolts through the baler frame require

Nyloc nuts.

11. Hang the two antennas (active on the left side) on the top brackets using the 3/8” x 1” hex head screws provided (do not fully tightened this stage). Move the bottom bracket around to line up with the bottom holes in the antenna and secure this place with the remaining screws. Now tighten up the four antenna screws on each antenna and then tighten up the bottom bracket bolts.

Figure 1 – Mounting Brackets

12. Run the flexible conduit that contains the microwave cable over the top of the rear baler frame and connect it into the antennae. You may need an adjustable wrench to tighten the conduit nut inside the antennae. Secure the conduit in place using large cable ties around the baler frame. Connect the microwave cable, taking care as per the special note about the microwave cable below this section.

13. Fasten a protection bar to each antenna support frame using the hex head screws supplied. The holes in these protection bars are tapped. Note the extended end goes up on both sides.

14. Run the cable from the active antenna to the baler draw bar position through the baler and secure using good quality cable ties. Secure the cable such that it will not make contact with any moving parts of the baler.

15. Secure the Terminal in the tractor cab using the RAM mount supplied.

16. Plug the power cable from the terminal into a 12V source. There are many brands of tractors with various "standard" connectors. Some modification of the 12V power connections may be required to get power to the moisture unit.

If you are using a John Deere tractor, use the John Deere power plug supplied to supply the 12V power. If you are not using a John Deere tractor, change the JD plug to one which suits your tractor, or hard wire the power into an appropriate

12V power source in the tractor. If an Auxiliary plug (cigarette lighter plug) is supplied, it should only be used for initial set up and testing, not ongoing use.

Many types of tractors are used, so it is not possible to supply one universal type of good quality connector.

A poor power connection can lead to inaccurate and erratic moisture

readings.

17. Connect the baler cable to the terminal. Secure this cable loom with cable ties or other appropriate cable securing mechanisms.

18. Do not put the spray cans in at this stage.

19. Move on to the set up procedures in section 2.7 of this manual.

4 sets of M10 x 30 hex head Bolts with M10 Nyloc nuts and flat washers.

4 M12 Nyloc nuts

870-E35-R01 Microwave cable assembly (1Yard longer than standard).

Overview:

This support system is attached to the two pairs of M12 bolts each side of the baler which secure the tail gate in place. Two brackets for each side are supplied so that only one bolt at a time is used to mount the Gazeeka support frame. In this way the tailgate is never left unsecured on one side. The longer microwave cable is supplied to allow the cable assembly to be routed between the two antennas using the existing structural cross member under the bale chute floor.

Procedure: (refer to photos below as well)

1.

Start on the left hand side of the baler (LHS facing forward). Loosen the front M12 nut and put the LHS short bracket on the bolt and re-secure the new M12 nut making sure that the top of the bracket is level (by using a small spirit level).

2.

Loosen the back nut and place the LHS long bracket over the bolt and tighten the new M12 nut only to the point where the bracket can still be swiveled around by hand.

3.

Place the LHS support frame in place and secure it to the two brackets using the two M10 bolts and nuts supplied. Tighten these up and then tighten the M12 tailgate nut up tight.

4.

Now, on the RHS, loosen the front M12 nut and put the RHS short bracket on the bolt and re-secure the new M12 nut making sure that the top of the bracket is level (by using a small spirit level).

5.

Loosen the back nut and place the RHS long bracket over the bolt and tighten the new M12 nut only to the point where the bracket can still be swiveled around by hand.

6.

Place the RHS support frame in place and secure it to the two brackets using the two M10 bolts and nuts supplied. Tighten these up and then tighten the M12 tailgate nut up tight.

7.

Place the active model 870S antenna (the one with the connector on it) in the LHS frame and secure it in place using the M10 bolts supplied. Make sure the bolt heads are on the inside to lower the chances of the chain snagging on an exposed bolt thread.

8.

Place the passive antenna in the RHS frame and secure it in place using the M10 bolts supplied. Make sure the bolt heads are on the inside to lower the chances of the chain snagging on an exposed bolt thread.

9.

Place the microwave cable assembly under the baler and present it to the antennas. Put this cable assembly into each antenna as described in the model 870S manual. READ THE

MANUAL.

RHS Support Frame LHS Support Frame RHS long bracket LHS long bracket RHS short bracket

LHS short bracket

10. Securely cable tie the microwave cable from each antenna down to the main cross member under the bale chamber floor, and along the back of the steel member.

870S V13p00 13

11. In the unlikely event that the spray from the spray can is blocked by the tailgate support chains, you may need to move them. If this is so, take out the two M6 screws holding the spay units in place and move them up one hole pitch (approximately 70mm). You may need to loosen the cable gland and even take the cover off of the antenna to make sure the cable to the spray solenoids reaches without being stressed.

12. Using tin snips or a sharp knife cut the rubber flaps to allow the chains to pass through (About

45mm diam. + horizontal cut in to the hole. (You may find these have already been supplied with the Krone mounting kit).

13. Now follow the standard installation procedure in the 870S manual.

870S V13p00 14

2.4

Installation - Extra notes

Notes on specific tractor 12V connections:

A. John Deere:

The Gazeeka model 870S comes supplied with a John Deere "Standard

Connector" John Deere part no. RE67013. This has connections via the "B"

(ground - black wire) and "C" (switched 12V - orange wire) pins. If your tractor is not a John Deere, then remove the plug and wire direct to a reliable 12V source.

Special Note

Of all the electrical issues, the microwave cables between the two antennae is the most critical. The microwave cable must always be enclosed in the conduit provided.

Since we are measuring down in the Pico-seconds (a millionth of a millionth of a second) excessive cable movements can cause errors. The conduit should be securely tied or clamped to prevent any movement. If the cables are re-routed for any reason, a new "air reading" should be carried out.

The microwave cable consists of an inner copper conductor surrounded by a dielectric material. Excessive bending of the cable will damage the dielectric and may cause inaccuracies in the moisture reading. These cables do not bend like normal electrical cables! The bending radius should be kept to greater than 6 inches.

The microwave cables are pre cut to suit the conduit lengths supplied with the instruments to ensure the cables are correctly terminated.

The tightening of the connectors on each end of each of the microwave cable is also critical. This should only be done with a proper SMA torque spanner (wrench)

[Huber & Suhner part no. 74Z0-0-21/ ] to 100 Ncm. If no torque spanner is available, then tighten using ones fingers to a snug tightness, then tighten an extra 45 degrees (about an eighth of a turn) with a small wrench. This is a poor substitute for a torque spanner and could lead to sub-optimal performance. If in doubt, it is best to just tighten a much as you can with your fingers.

2.5

Environmental Considerations

The Gazeeka Model 870S moisture monitor is rated IP55 (NEMA 4), which means that it is protected against the ingress of dust and moisture to a reasonable degree.

The instrument is rated from zero to 55 degrees Centigrade.

2.6

Licensing Issues

The Gazeeka model 870S moisture monitor operates at specific frequencies and such low power levels such that licensing is not required.

870S V13p00 15

2.7

Commissioning / Setup

Commissioning (sometimes referred to as setup) commences with a physical inspection of the installation. The checks will include, but not be limited to the following:

1. Make sure all the mounting fasteners are tight and the antennas are rigidly mounted. (Note that any repositioning of the antennas will require a new air standardization to be carried out).

2. The horizontal center line of the antennas should be approximately at the same horizontal center line of the bales to be measured and any tailgate support mechanisms should not be in the line of the microwave beam.

3. All reasonable efforts need to have been made to minimize any interference to the microwave measurement signals.

4. All electrical cables correctly routed and terminated.

5. Power up the monitor in the tractor and check that the LCD display says

"Analyze".

6. Press the F1 key and enter the correct parameters for your application. See the section on editing parameters and the parameter list in Appendix A to carry out this task. The following points cover some of these important parameters.

7. Make sure that the width of the bale (approximately to the nearest inch or so) to be measured is entered in the "Thickness" parameter in Inches (typically a 3 foot bale = 32 inches and a 4’ bale = 48 inches). (see Parameter Table and section

3.8 for more detail).

8. Select the correct equation for the type of hay you are baling (see Parameter

Table).

(You can do this later if you wish. See section 3.3 – Normal Operation to lean how this and other variables can be changed (edited) very simply by using the Field Key during normal Analyze mode).

9. If you want the Terminal unit to give an audible sound (Beep) and mark the bale if the moisture goes above a given moisture, then enter these values in the appropriate parameters (see Parameter Table).

(You can do this later if you wish.

See section 3.3 – Normal Operation to lean how this and other variables can be changed

(edited) very simply by using the Field Key during normal Analyze mode).

10. The spray units will active when the high moisture beep goes off in the tractor cab

Terminal. Note that the spray units can be tested at any time in the normal analysis mode by pressing the UP arrow on the keypad.

11. Please note that in normal operation, the system only draws just less than half an

Amp, however when the spray solenoids operate, up to 7 Amps may be drawn for a short duration. Ensure that any fuse protections had the capability of this current draw.

12. After at least a 10-minute warm up period, initiate an Air measurement and ensure that no error conditions are displayed (Section 6.2). If error conditions are displayed, fault find and rectify the problem. Error conditions are listed at the end of Appendix A.

13. After the air reading is done and the parameters are set, the system is ready for use.

Note, there are only 3 fundamental things that need to be done to give a reasonable moisture analysis.

1. Set the bale width correctly (need only be done once for that baler)

2. Do an air reading

(this should last forever, but once a season is good)

3. Select a calibration.

Used to increase the value being highlighted by the cursor.

DOWN Used to decrease the value being highlighted by the cursor.

Your Model 870S Moisture Monitor can be in one of only two operational modes:

Setup Mode or Analyze Mode.

When power is first applied to the Model 870S Moisture Monitor, the instrument automatically goes into Analyze Mode ready to measure moisture in a bale.

In Analyze Mode, use the F1 key to select the Setup Mode.

See Appendix A for the Menu structure, Item and Parameter listings.

You use the [menu] key to move through the menu list and the [item] key to move through the items on each menu. (See Appendix A for a complete list).

The Model 870S uses a 2 line, 16 character per line LCD display to allow you to view the Items in different Menus and their values. You may also use the keys to change some of the values, to allow the Model 870S to adjust to your conditions.

870S V13p00 18

3.3

Normal Operation

The Gazeeka Model 870S moisture monitor has two modes called Setup and

Analyze. Upon power up, if there are no faults found during power up tests, the instrument automatically goes into Analyze mode.

In Analyze mode a moisture reading is taken within a programmable time after the bale detected input is activated.

The LCD display will indicate that the instrument is in Analyze mode, and will display the current moisture value as the last instantaneous moisture value and the average moisture value:

READING S19 LEG

I 17.1 P 22.8 A 18.0

I

P

is the Instantaneous Moisture at each reading is the peak moisture for the averaging period

A

is the average moisture value for the averaging period

Displaying current status

The first 8 characters on the top line display the current status of the instrument.

The Sxx (shown above set to S19) is the moisture value at which the terminal gives out a "beep" and the bale is marked by the spray cans.

The last three characters on the top line display the equation being used to convert the microwave readings to moisture readings. There is a universal calibration equation which may be used at any time, but using the appropriate calibration equation for the type of hay you are baling will give the best results.

The current calibrations are: UNI

FES

OAT

LEG

OMX

(Universal 1)

(Grass Hay)

(Cereal Hay)

(Legume Hay)

(Oat Mix)

Changing the spray point moisture and the calibration equation using the

FIELD key.

At any time, you may change the moisture value at which the spray cans operate. To do this, press the FIELD key and the cursor will move under the "S". Now use the UP or DOWN keys to change this value. Note that after 5 seconds of inactivity, the cursor will revert back to its home position.

At any time you may also change the calibration equation for the type of hay you are baling. To do this, press the FIELD key twice and the cursor will move under the calibration equation selection area. Now use the UP and DOWN keys to change to the type of hay you are baling. Note that after 5 seconds of inactivity, the cursor will revert back to its home position.

At any time when the cursor is in its home position, the UP key will mark the bale.

Some operators like to use this facility to mark a bale for some special reason other than its moisture content.

Please note that the "beep and Spray" moisture value and the calibration equation selection can also be done in the setup mode via the standard menu structure.

Warm up.

Please note that under normal environmental conditions it may take up to two minutes before the analyzer will be operating to its optimal performance.

870S V13p00 19

Setup Mode

The Setup mode allows you to setup and standardize (air reading) the Model 870S to your specific conditions. The standard air reading should be done at regular maintenance intervals and after extended periods of operation (for example at the beginning of each season).

3.4

Alarm Conditions

If a fault or alarm condition occurs, the LCD will indicate what type of fault has occurred.

3.5

Calibration Standards

Please Note

This instrument has been calibrated to read moisture with respect to oven dried samples using the American Society of Agricultural Engineers

Standard ASAE S358.2 Dec99 "Moisture Measurement – Forages".

If readings differ from another method used for contractual purposes, then any average difference (bias) should be taken into account by the operator when using the readings produced by this instrument.

NB0509301

The Model 870S is only calibrated for cured hay. Using this instrument on uncured hay or silage is not recommended.

870S V13p00 20

Safety Considerations

Microwave radiation Safety Considerations 2004.

The power levels of the microwave signal being radiated from the Gazeeka moisture meter are in milli-Watts and do not constitute a health risk. However, if there is no need for anyone to be in the beam between the antennae when the unit is on, don't do it, as it is best not to be exposed to any more microwave radiation than is necessary, and moreover, the results from the instrument will become meaningless with any part of the human body in the microwave beam.

For microwave radiation, the maximum occupational exposure set out by Standard

AS2772.1 is 1mW/cm

2

.

The average radiation level at the surface of the antenna is normally less than

0.0001mW/cm

2

( even less 5 cm away). This is 1000 times less than set out by the

Australian standard.

If during reading a moisture, the instrument finds that the combination of density and moisture is such that the bale is absorbing too much microwave energy for the signal to be reliably measured on the other side of the bale, the instrument will raise the power level to 0.05mW/cm

2 for the duration of the analysis time only. All EMC tests have been carried out at this higher power level.

For comparison only. In the USA and other places in the world, microwave ovens are limited to a maximum leakage of 5mW/cm

2 at a distance of 5cm from the oven surface. Another example is of a well known brand of Cell Phone which has a RF

Power Density of 3.0 mW/cm

2 next to the antenna, and 1.2 mW/cm

2

@ 5 cm from the antenna.

5.

Compliance issues

IMPORTANT NOTE.

To ensure that the instrument maintains its electromagnetic compatibility and electrical safety rating, the physical and electrical arrangements and component choice must remain as the instrument was supplied. All interfacing to the control cabinet must be carried out as per the drawings supplied in this manual.

Safety Compliance

This instrument has be designed and tested where necessary to meet international standards for electrical safety.

Environmental Protection Compliance (IP / NEMA rating)

This instrument has be designed and tested where necessary to meet international standards for environmental protection.

IMPORTANT NOTE.

To ensure that the instrument maintains its environmental protection rating, any holes put in the outer skin of the control cabinet, or use of cable glands etc. must be properly sealed up before use.

870S V13p00 21

6.

Maintenance Procedures

Antenna alignment

Antenna alignment should be regularly checked. The distance between each of the four corners should be the same +/- ¼ inch. Alignment offsets can be checked with a

"straight edge". Note that if re-alignment was required, a new air standardization will be required to be carried out. Actual alignment is not as critical as the alignment remaining the same after an air path reading (air standardization) has been carried out.

Microwave interference

Examine the installation and its surrounding for microwave interference effects as described in the installation section and correct if necessary.

Antenna Repairs

Should any damage occur to a microwave antenna, please ensure that your Gazeeka agent is notified so that repairs can be carried out. The antennas are generally not repairable in the field.

Instrument stability

If any corrections or changes had to be made during maintenance, ensure that ”air standardization" is carried out to ensure there has been no drift in the calibration. All moisture readings are referred back to an air reference standard.

Position of Links and switches

Make sure all links and switches are in their correct positions.

6.1

Calibration and Standardisation

The in-built calibration system is based on theoretical models that have been derived by Gazeeka and verified both in the laboratory and in the field on hay bales. All of the calibrations are referred back to the empty path air measurement. Thus, the empty path air measurement has an important role in maintaining the calibration accuracy.

The Model 870S is only calibrated for cured hay. Using this instrument on uncured hay or silage is not recommended.

Comparisons with other moisture measuring methods

Sometimes other methods are used to measure the moisture of the bales. In some cases, different readings may be obtained using these methods. These "other" methods may not be as accurate as the Gazeeka method, but it may be the method upon which payments are made.

In cases where you may want the Gazeeka reading to more closely reflect this "other" method of measurement (even if the "other" method is not as accurate) you may put an offset into the model 870S unit to match the other readings. For example, if the you believe the "other" reading is reading 2% higher than the Gazeeka unit you can raise the average readings of the Gazeeka unit by putting a value of 2 into the

"Offset" parameter in the Gazeeka unit. Negative numbers can also be entered into the Offset parameter if required.

870S V13p00 22

6.2

Air Standardisation

An "air standardization" must be carried out at the time of installation, and should also be carried out if there are any physical changes to the installation and at the start of each season. This operation is carried out as follows.



Make sure the instrument has been on for at least 10 minutes.



Make sure the air path between the antennae is clear (i.e. no bale or anything else). The end of the bale should be inside the rear end of the baler

doors by at least a foot.



Select the Setup Mode - If in Analyze Mode, press [F1] to select the Setup mode.



Press [Item] to select the “ENT for Air Cal” item.



Press [ENT] to select an air path reading to be carried out.



Clear the air path and press [F1]. Press [ENT] to calibrate - it will take a few seconds.



If no error message displayed, the air path standardization has been completed OK.



Press [ENT] to go back to the Setup Menu.



The instrument is now ready to start measuring bales again.

870S V13p00 23

6.3

Maintenance of the Spray Solenoids

Note: The solenoids are not continuously rated. The Model 870S software ensures that the solenoids are not operated for more than their designed duty cycle.

The solenoids are marked 6V, that is their continuous operating voltage. They may be operated safely and reliably at 12V or even 24V with a reduced duty cycle. Using a higher voltage with a reduced duty cycle provides extra power.

The maximum thrust of the solenoid is when the armature (moving part) is close to its maximum travel position. This is the point at which it should be making the can spray.

Equipment list:

1. Small flat blade screw driver.

2. 3mm Allan key

3. #2 pozi drive (or Phillips head) screw driver.

4. Long nose pliers.

5. Thread locking compound such as Loctite 243.

6. 3mm (1/8") gap measurement rod (e.g. M3 (1/8") screw, 8 SWG wire)

Procedure:

1. Remove the screw holding the metal cap on the solenoid housing. Remove the cap.

2. Remove the M4 stainless steel plunger bolt using the

Allan key while preventing the plunger from turning using the small screw driver.

3. Remove the plunger and clean the inside cavity of the coil including in particular the conical section at the end. Clean the plunger.

4. Place the plunger (with its spring in place) back into the cavity.

5. Ensure the M4 stainless steel plunger has 5 "O"-rings on its shank (Type BS105). These are used to stop dust getting up into the solenoid cavity and also to determine the correct location of the plunger from the spray can.

6. Place Loctite on the thread of the plunger bolt and using the screwdriver to hold the plunger from turning, screw the bolt in.

7. Pull the plunger fully downwards and measure the travel. Screw / unscrew the plunger until it has 7mm (+/- 0.5mm) of movement between its rest position against the 5 O rings and the fully pulled down position. (Out 17mm at rest and 24mm when extended).

8. Replace the metal cap on the solenoid housing and 8g screw to hold it in place.

9. Make sure that dust or other foreign material is absent from under the spray can cap.

10. Make sure the cap is firmly down on the spay nozzle of the spray can, especially on new cans where the factory process often leaves the cap loose. This will require you to spay some material from the can by pushing down hard on the cap.

11. Insert a spray can and measure the gap between the top of the spray can cap and the plunger, this should be about 1/8". Use a drill bit or some 8SWG wire to check this. Bend the tongues of the can retainer plate to adjust this gap.

12. Test the unit after about four hours, as sometimes excess Loctite may bond the plunger to the solenoid body. This is easily feed up by manually pulling the plunger down to release the bond.

870S V13p00 24

7.

Fault Finding

As with most electronic equipment there are usually only two things that fail in the vast majority of cases. These are power supplies and electrical connections. Given this, these are the first two things to check if a fault is suspected.

Check that the 12V dc supply is going to the microwave antenna and the LCD display.

Connections can be checked with a meter, and by gentle movement of the wires, plug, connector or terminals. Depending on the fault conditions (symptoms), logic should tell you generally where to check.

The third most common fault in instruments such as these is the "finger problem".

Sometimes an instrument is left with a wrong value entered into the memory. This can be a particularly difficult problem, as often the wrong value which has been keyed in will only affect the results in a subtle way, and it is often some time before someone notices that the "results do not seem right". By this time the fact that the numbers were edited has been forgotten. The only solution is to re-check all the

Parameters against the values as logged in the back of this manual. This is why it is important that whenever a change is made that the change is noted in the space provided in the parameter listing in this manual.

Can not spraying correctly

In some very dusty environments, dust may penetrate into the base of the solenoid plunger and prevent proper operation of the system. In this case, follow the above section on maintenance of the spray solenoids.
