Introduction

MT-3405 M

Your new MT-3405 M system is a high-performance controller, designed for superior control of product applications with features to help you manage your operation efficiently. From the large liquid crystal display and user-friendly controls to the Windows-compatible Utilities Software, the system is designed with the operator in mind. Some of the built-in features are described in the following paragraphs.

5Boom Automatic Rate Control System

MODULARITY

Installing your MT-3405 M is cleaner and easier since only a single four-wire cable is required to connect sprayer functions to the console. The sealed electronic module has inputs for flow, run/hold, speed and (optional) pressure sensors. In addition, it has outputs for flow regulation, relief, and up to five boom shut-off valves. The system easily adapts to most solenoid- or motor-driven boom shut-off valves.

INTEGRATED CONSOLE

The MT-3405 M console houses all operator controls in a single weather-resistant case. Battery and sprayer cables are equipped with environmental connectors while a standard serial cable connection is provided for easy VRT hook-up.

IMPROVED ADAPTIVE CONTROL

The MT-3405 M system uses advanced control methods to adapt to your applicator system automatically, completely eliminating the need to “fine-tune” the console for best performance. Adaptive control has always been included in Micro-Trak controllers, and has been further refined in the MT-3405 M.

FLEXIBILITY

The MT-3405 M can be configured to control liquid, NH3 or properly equipped dry material applicators. The MT-3405 M can control your liquid applicator in three ways. “Flow Only” uses the flowmeter feedback only, and can be used with or without a pressure sensor. “Pressure Only” uses feedback from the pressure sensor only, and can be used without a flowmeter. “Hybrid” uses feedback from both the flowmeter and the pressure sensor to provide optimal control response and accuracy. Operation in either “Pressure Only” or “Hybrid” control mode requires installation of a pressure sensor and proper calibration for the nozzles you are using.

UTILITY SOFTWARE CD

In addition to the operator’s manual in PDF format, your CD has the Utility Software program. This program uses a calibration “wizard” to direct the operator through the MT-3405 M calibration process and automatically sets up calibration for various types of systems. Information for different applications may be stored in files for convenient re-entry into the console. Calibration settings may be printed for manual entry into the console. Alternately, the MT-3405 M may be connected to the PC for calibration downloading as well as uploading field data and upgrading the MT-3405 M’s Flash program.

RS232 SERIAL INTERFACE

The MT-3405 M serial interface allows the console to be linked to most desktop or laptop computers. This serial link can be used to calibrate or reprogram the console using the Utility Software package. It can also be used with appropriate software such as Farm Works SiteMate™ to accomplish variable rate application (VRA), or as a data logger to download accumulated data and calibration parameters to the PC at intervals commanded by the PC program. The MT-3405 M system also offers VRA shut-off control for individual booms.

TIME TESTED MICROTRAK FEATURES

An (optional) run/hold sensor automatically turns off the entire sprayer when equipment is raised, minimizing operator workload at a critical time. The ADJUST RATE feature allows the operator to change the application rate by a preset amount with the push of a button. An electric relief valve is recommended for systems that can exceed the permissible pressure when all booms are off. The MINIMUM FLOW setting maintains a good spray pattern at low speeds. Semiautomatic calibration (FINETUNING) allows exact calibration of speed and flow sensors with a minimum of effort.

NOTE TO THE USER

The MT-3405 M is written using English units of measure, but is capable of operating in Metric and Turf units as well. The “Units of Measure” chart shows the units of measure for each function that is controlled by the MT-3405 M. This chart is shown several times throughout the manual, and is referred to by the “+” sign.

Electrical Installation

The MT-3405 M must be connected to a 12-volt DC electrical system. Power is connected directly to the battery. The MT-3405 M has an ON/OFF switch on the console to turn the power off when the system is not being used.

Locate the power cable harness and connect to the mating connector on the console. Connect the blue chassis ground wire to a good frame ground. See Illustration 3. Make sure there is good metal-to-metal contact. Route the power cable from the console to the battery. Cut off excess length. In routing cable to battery, avoid ar eas where the ca ble may be subjected to abrasion or ex ces sive heat. Install the in-line fuse provided with the kit on the white wire, as illustrated, to protect the circuit. Connect the WHITE wire (hot) to the positive battery terminal. At tach the BLACK wire (ground) to a screw or bolt on the equipment frame. See Illustration 3. Be sure there is good metal-to-metal contact.

Illustration 3

NOTE: For negative ground systems ONLY.

Your MT-3405 M is equipped with an ad vanced elec tronic mem o ry which does not re quire a con stant supply of power to re tain daily totals or calibration val ues. The advantage with this type of memory is that it conserves battery power and will not dis charge the vehicle’s battery when equipment is not in use.

Mounting the Module

INSTALLING THE BRACKETS

To install the module brackets, crimp a terminal to the blue ground wire. Fasten the brackets to the module as shown, and install the crimped blue wire under one of the screws holding the bracket to the module. See Illustration 4.

INSTALLING THE MODULE

Select a mounting location for the SC-3405 module that will provide enough cable to reach both the console and each of the plumbing components. Fasten the module and brackets to the equipment frame or other equipment location using bolts or self-tapping screws. Cut the blue wire to a suitable length. Crimp on terminal and connect to good chassis ground. See Illustration 4.

Follow the wiring diagram shown on page 14. Use extension cables to connect the 4-pin W/P shroud to the 4-pin W/P tower of the console.

INSTALLATION NOTE: To avoid non-warranty moisture damage to the module, route module cables so that the connectors are lower than the module.

Speed Sensor Installation

PLEASE NOTE: If you have purchased a Trak-Star speed sensor, disregard the section on magnetic speed sensors and install the Trak-Star as described in the instructions packed with the unit.

Locations where the sensor may be installed:

Non-driven wheel on tractor, vehicle or implement. This 1. is less susceptible to errors resulting from wheel slip.

Magnets

The number of magnets that must be used depends on where you mount the sensor. The general rule for tractor or implement wheels is one magnet for each wheel bolt (minimum of two, and always use an even number). For drive shafts or small wheels (ATV’s), two magnets are generally sufficient.

The magnets provided by Micro-Trak are marked with a dashed line on the SOUTH pole side of the magnet. See

Illustration 5.

NOTE: Always use an even number of magnets, and always alternate the polarities of the magnets as you go around the wheel hub or drive shaft.

• Speed Sensor Cable • Mounting “L” Bracket

• Magnet Clips • Magnets

• Cable Ties

Tractor, vehicle or planter drive shaft. This type of 2. mounting is recommended for trucks, four-wheel drive tractors or other equipment that has poor or no access to a non-driven wheel.

Illustration 5

Illustration 6

To install, mount the first magnet with the SOUTH pole side (dashed line) facing toward the hub or shaft. The long dimension of the magnet must wrap around the hub or shaft. Mount the second magnet with the NORTH pole side facing toward the hub or shaft. See Illustration 6.

For proper operation, the magnets must be evenly spaced around the wheel or drive shaft. The magnets must be at least 1” apart. See Illustration 7.

Attaching Magnets

Refer to Illustration 8 for general mounting instructions. For specific mounting instructions, refer to Appendix A in the back of this manual.

NOTE: Magnets may be attached mechanically as shown or adhered with epoxy or other high quality adhesive. When using adhesive, thoroughly clean the area of dirt and oil.

Speed Sensor Installation (cont)

Mounting Speed Sensor

Use bolts or self-tapping screws to mount the bracket so that the sensor is aligned directly over the magnet. (Bracket may be attached by other means such as welding.) When the wheel or drive shaft begins turning, a speed impulse is sent to the MT-3405 M console every time a magnet passes by the tip of the speed sensor. For the speed sensor to operate properly, the spacing between the magnets and the tip of the sensor must always remain constant. Before permanently mounting any parts, be sure that the location you have selected will meet the following requirements.

See Illustration 9.

CAUTION: To ensure that no console damage occurs, disconnect all system cables before welding.

Speed Sensor Options

In addition to the standard Hall-effect magnetic speed sensor, the MT-3405 FTW may be interfaced with a va ri ety of other speed sensing equipment. Several options are listed below.

Illustration 9

ASTRO SERIES OR OTHER GPS SPEED SENSOR INTERFACES

The MT-9000 may also be used with most GPS speed sensors that output a pulsed signal, such as the Micro-Trak Astro II and 5, SkyTrak or Dickey-John GPS speed sensors. An adapter cable may be required.

VANSCO™ RADAR SPEED SENSOR

The Vansco radar speed sensor uses a microwave (radar) signal to deliver a reliable, accurate speed signal for electronic equipment. It features state-of-the-art electronic design/ manufacturing, rugged aluminum housing and complete testing and certification.

RADAR INTERFACE

The MT-9000 may also be interfaced with most popular radar ground speed sensors. An adapter cable is re quired for proper interface.

SEE APPENDIX H FOR LIST OF ADAPTER CABLES FOR RADAR.

Speed Sensor Installation (cont)

Connecting the Speed Sensor Cable

The speed sensor cable has a GREEN sensor body and mates with the main harness cable having a YELLOW cable tie near the 3-pin M/P connector. Make certain that you install the correct sensor cable and connect it to the correct connection point on the module. The speed sensor and the flow sensor are identical, but must be connected to the proper harness connector. The speed sensor always connects to the main harness lead with the YELLOW tie and flow sensor always connects to the main harness lead with the GREEN tie.

See Illustration 10.

INSTALLATION NOTE: The MT-3405 M system provides two connection points for the speed sensor. For speed sensor installations in the cab or near the control console, it may be more practical to use the local access connector (YELLOW tie) exiting the rear of the console. Using this

connection point will disable the connection point on the module. For speed sensor installations on implements, it may be more practical to use the speed connector exiting the SC-3405 Module. A dust cover should be installed on the unused speed connection point.

Mounting and Plumbing Flowmeter

The flowmeter must be installed in the boom supply line after any strainers, return lines, or valves, but before the boom shut-off valves. Se cure ly mount flow me ter (hardware not supplied) in a vertical position in an area away from in tense vibration. DO NOT install flowmeter closer than 12” to the servo valve or the boom shut-off valves. (The flow-

me ter may need periodic cleaning, so it should be easy to remove.) The flow meter is a bidirectional meter (exception: Polmac’s 1 ½” - 3”). Liquid can flow in either direction, but

up is preferred. Make con nec tions us ing 3/4” fit tings without the use of reducers, elbows or sharp bends for a minimum of six inches (15 cm) either side of meter. See Illustration 11.

NOTE: Save plastic plugs to protect flowmeter during storage.

Illustration 11

Installing Flow Sensor Cable

With the flowmeter in place, install the flow sensor cable (GREEN body). See Illustration 12.

Screw sensor all the way into hole of flow me ter. Tight en 3/8” jam nut to lock sen sor in place.

Uncoil flow sensor cable and carefully route it to meet the module flow cable connector marked with GREEN tie. Align connectors and press firmly together until locking tab clicks into place. Secure cable with ties provided. See

Pressure Relief Valve

If you have a positive displacement pump or a cen trif u gal pump capable of generating excessive pressure, you must in stall a pressure relief valve and adjust it to a safe max imum pressure. If a positive dis place ment pump is operated without a pressure relief valve, damage may re sult to pump or other plumbing component. See Illustration 14.

Illustration 14

For Positive Displacement Pump

Range Adjust Valve

With oversized pumps, it may be necessary to install a range adjust valve. The range adjust valve will reduce the pump’s output to the rest of the system. Ad just ment of this valve is covered in the Pre-Field checkout, pages 31-32. See

Illustration 15.

Installing Pressure Sensor

If you are using a pressure sensor, it must be installed before the boom shut-off valves in your plumbing configuration.

Install the pressure sensor in the main sprayer line as close to the boom shut-off valves as possible. See Illustration 16. Locate the flow/run/hold cable harness and connect to the mating (2-pin) connector with the NATURAL tie . Connect the blue chassis ground wire to a good frame ground. Make sure there is good metal-to-metal contact.

NOTE: The console display area for pressure will be blank until initial nulling is complete.

Illustration 15

For Oversized Pumps

Pressure Sensor

To null the pressure sensor:

Place the 1. RUN/HOLD switch in HOLD.

Turn the rotary dial to 2. PRESSURE.

Press and hold the “ - ” switch for three seconds. A “0” 3.

should show on the display.

NOTE: The pressure offset can be re-nulled if a new sensor is installed, or at any time, but the display cannot be blanked once it is set. (In other words, if the sensor is removed, the

pressure display will still show a value, not blank).

Installation (cont)

Servo, Throttling Valves

The servo valve installs in an unrestricted return line to the inlet of the pump or directly into the tank. DO NOT install the servo valve closer than 12” to the flowmeter. The servo valve has a flow direction decal on it. Make certain that the actual flow direction matches the decal on the servo valve. Do not install the servo valve in the agitation line. Slow response time and marginal operation may result. The return line should tee from the main line just after the throttling valve. See Illustration 17. The throttling valve is used to limit the output (set maximum output) of the pump to the flowmeter and servo valve. The throttling valve is adjusted to put the servo valve in its optimal operating range. Please refer to Pre-Field System Checkout for proper valve adjustment procedure.

The servo valve connects directly from the module to the 3-pin W/P connector (NO tie). If more length is required, use a 3-pin W/P extension cable of the appropriate length. If using a Braglia or other 12-volt control valve, please refer to

Appendix C.

Relief Valve

The relief valve is used to “dump” pressure when all boom valves are turned off. Whenever all the boom control switches are turned off, or when HOLD is selected with the master switch, the relief valve should be open. Use this plumbing illustration (See Illustration 18) as your pattern for proper installation if your relief valve has a flow-through port. DO NOT install the relief valve closer than 12” to the flowmeter. Locate a 2-pin solenoid cable and connect it to the relief valve using an appropriate method. Connect a 2-pin M/P connector to the module cable with no colored tie. Be careful not to connect the relief valve cable to one of the boom shut-off leads. All of the boom shut-off leads have a colored tie near the 2-pin M/P connector. The relief solenoid lead does not.

Illustration 17

NOTE: The servo valve may be installed in the main spray line (in-line). For in-line use, you will need to calibrate for in-line (see Calibration section). Failure to set for in-line will result in backwards operation of the servo valve.

Illustration 18

If all valves are NOT the same type (all solenoid or all ball valves), refer to Appendix B for wiring instructions.

If your relief valve does not have flow-through port, you must add a “T” fitting. See Illustration 19.

NOTE: To as sure a good con nec tion and avoid corrosion, coat electrical connections with sil i cone grease.

Boom Shut-off Valves

Plumb boom valves with flow-through port as shown. Boom valves of differing designs may require a “T” fitting. See Illustration 20. Make certain to use adequately sized plumbing lines to avoid ex ces sive pressure drops. DO NOT install the shut-off valves closer than 12” to the flowmeter.

Locate the boom shut-off cables. Crimp the insulated female quick disconnect terminals provided with the cables to both wires. (If valves have wires, crimp mating terminals on those wires). Attach the cables to the terminals on the boom valves. Normally, wires connect red to red and black to black. If valves operate backwards, reverse connections. Apply silicone grease to the ter mi nal connections to help prevent corrosion and insure a good electrical con nec tion.

Locate the colored cable ties included with the boom shut-off cables. Attach a BROWN tie near the 2-pin M/P connector on the boom one (1) cable. Attach a RED tie near the 2-pin M/P connector on the boom two (2) cable. Attach an ORANGE tie near the 2-pin M/P connector on the boom three (3) cable. Attach a YELLOW tie near the 2-pin M/P connector on the boom four (4) cable. Attach a GREEN tie near the 2-pin M/P connector on the boom five (5) cable.

Connect the 2-pin M/P connectors to the mating con nectors on the module. Boom one (1) connects to the mating connector with the BROWN cable tie near the connec tor. Boom two (2) connects to the mating connector with the

Remote Run/Hold

The MT-3405M system provides two connection points for the run/hold. For run/hold in stal la tions in the cab or near the control con sole, it may be more prac ti cal to use the local access con nec tor (GRAY tie) ex it ing the rear of the con sole. For run/hold sensor in stal la tions on im ple ments, it may be more practical to use the run/hold connector at the module. A jumper cover must be installed on the unused run/hold connection point or the system will always be in HOLD and the boom control valves will not function.

The run/hold sensor cable has a black body and a GRAY tie near the 3-pin M/P connector and mates with the module cable having a GRAY cable tie near the 3-pin M/P connector. Make certain that you install the correct sen sor cable and connect it to the correct connector on the module. The run/ hold sensor has a BLACK body. DO NOT use a speed/flow sensor (GREEN body). See wiring diagram on the previous page. A jumper cover should be installed on the unused run/ hold connection point.

Attach a magnet to a lever or some part of the • equipment that moves when the im ple ment is raised and lowered. The Hall-effect run/hold sensor is sensitive only to the south pole (side with dashed line) of the magnet. Check the polarity of the magnet by bringing it near the run/hold sensor with the console turned on. Note and mark the face of the magnet that is toward the sensor when the console does not indicate “HOLD.” When the mag net is away from the sen sor, the con sole will be in HOLD and will shut off the boom valves and stop count ing acres.

Rockshaft Control Lever Mounting

Hydraulic Cylinder Mounting

Magnet and sensor are in line when equipment is lowered and operating.

Lift Wheel Mounting

NOTE: The run/hold kit includes a 5’ sensor cable and 10’ extension. You may re quire additional extension cables which are avail able in 5 ft. (1.5 m), 10 ft. (3 m), 15 ft. (4.5 m), 20 ft. (6 m) and 25 ft. (7.6 m) lengths.

You may also use a toggle or other type switch. Sim ply • cut the blue jumper wire in the dust cover and splice on an appropriate length of wire to reach your switch. When switch is closed, console is in RUN. When the switch is open, the console is in HOLD.

NOTE: Do not apply power to run/hold wires.

Once the desired boom section has been selected, turn the rotary selector to width to enter the effective work ing width for that boom section. Re peat this pro ce dure for each boom section.

The console will remain in calibration mode, with the RED warning light flashing, until you exit calibration or turn off power.

Once in calibration mode, you may change any one, all or none of the values, in any order.* To select a calibration position, simply turn the rotary selector to the desired position. Calibration positions are to the outside of the rotary positions, in white lettering with red outlined boxes. All values are adjusted using the “+” and “-” but tons on the front panel.

IMPORTANT NOTE: Test speed must be last.

Your “working” width will vary depending on the type of equipment you are using and the method of application. For example, if you are broadcast applying chemicals your “working” width will be the number of nozzles times the nozzle spacing in inches (meters). For example, if you have 20 nozzles spaced at 20 inches, the working width is 400 inches.

See Illustration 24.

Setting Individual Boom Width

In order to accurately measure the number of gallons applied per acre it is important to determine the correct “working” width. The “working” width is the width of ground being affected by any operation. This should be measured to the nearest inch (millimeter).

Banding Application Calibration

In banding applications, you will still need to enter the total width of each boom section so that area counts correctly, but you must also calculate the percentage of your total width the band is covering and reduce your target rate to match. For example, if you are planting with an eight-row planter with 30-inch spacing, your total working width, regardless of the width of bands, is 240 inches (8 x 30 inches). Now, for purposes of this example, you have eight 12” bands. Your total band coverage is 96 inches (8 x 12 inches). Based on that, your band is covering 40 percent of your total width (96 divided by 240). If you want to apply 20 GPA in the band, enter 8 GPA as your target rate (40 percent of 20 GPA). See

Illustration 25.

CIRC: This position is used to calibrate the speed sensor

Determining Wheel Circumference

For the console to calculate the correct number of acres, both the circumference of the sen sor-equipped wheel and the implement width must be entered. Determine the circumference of the sensor-mounted wheel to the nearest tenth of an inch (millimeter) with the fol low ing method:

METHOD

Mark tire with a piece of chalk and mea sure distance traveled on the ground for one com plete revolution. See Figure 3.6. For accuracy, measure the wheel rev o lu tion sever al times and take the average. Divide that val ue by the num ber of magnets installed on the wheel hub to get your starting wheel cir cum fer ence (CIRC) calibra tion val ue.

To determine circumference, measure the

distance of one complete wheel revolution

and divide by the number of magnets installed.

Drive Shaft Speed Sensor Calibration

NOTE: If you have mounted the magnetic speed sen sor on a wheel, skip this step and go on to Fine Tuning Speed/ Distance Calibration Values. To fine-tune the wheel circum fer ence (CIRC) value, turn to page 27.

Because of the difference in wheel-to-drive shaft ra tios, it is difficult to determine a calibration value for installation on a drive shaft by measuring a wheel. You must start with an estimated calibration value and then fine-tune the calibration.

Place the console in HOLD.1.

Press and hold the “CAL” key for three sec onds to 2. en ter the cal i bra tion mode. Turn the dial to “CIRC” po si tion. The display will alternate between the wheel circumference (CIRC) and dis tance values at about threesec ond intervals. (When the word “CAL” appears, the num ber dis played is the wheel cir cum fer ence (CIRC) value. When “CAL” does not appear, this is the dis tance value.)

When the display shows wheel circumference (“CAL” is 3. displayed) , use the “+” or “-” key to adjust the displayed value to 1.75. Exit “CAL” by press ing and holding the “CAL” key for three seconds.

NOTE: If you let go of the “+” and “-” keys while you are ad just ing the CIRC value, the console will wait to make sure you are finished. After 64 sec onds, the dis play will start al ter nat ing be tween the wheel cir cum fer ence (CIRC) and distance values again. Make sure you know which value you are adjusting.

FLOW CAL: This po si tion is used to calibrate the flow me-

ter for ac cu rate liquid mea sure ment. When this po si tion is selected, the display will alternately show, every three

seconds, the flowmeter calibration value and the total flow value. The flowmeter calibration

value is the number shown

along with “CAL” on the display. The total flow value

is the number shown when

“CAL” IS NOT displayed. The flowmeter calibration value is typical ly selected when entering the calibration number from the tag attached to the flowmeter. Enter the calibration value stamped on the tag attached to the flowmeter. The total flow value is typ i cal ly selected when you are fine-tuning the flowmeter cal i bra tion (please refer to Fine-Tuning Flow- me ter Cal i bra tion). To select either one of the values for calibration, simply press the “+” or “-” button when the val ue you want to select is being displayed. Once selected, the display will stop al ter nat ing between the two figures for one minute to allow you to make the appropriate ad just ment. After one minute follow ing your last adjustment to the value, or after you move the rotary selector away from and then back to the FLOW CAL position, the display will alternate between the two values.

Every flowmeter is calibrated with water at the factory. If your spray solution has a specific gravity or viscosity that is different than water, flowmeter calibration should be done for the specific solution (please refer to Fine-Tuning Flow meter Calibration.)

Your Micro-Trak flowmeter has been tested at the factory and assigned a “FLOW CAL” value to make it operate properly with the MT-3405 M console. This number is stamped on the metal tag attached to the flowmeter. See Illustration 37. This is a starting point only. The value must be fine tuned. See Fine-Tuning Flowmeter Calibration

MIN FLOW/PRESSURE: The pur pose of this calibration

parameter is to set the minimum recommended flow rate for the spray boom and the minimum recommended pressure for the nozzles. Once set, the system will

prevent the actual flow rate

and pressure from going

below the recommended

minimum rating.

CALCULATING MINIMUM FLOW VALUE

Determine from your tip chart what your nozzle’s minimum gallon per minute+ rating is at their minimum recommended pressure. Do not use the gallon per minute rating of your actual application rate. For example, if the minimum flow rate per nozzle is .22 GPM at their minimum pressure and your spray boom has 20 nozzles (all sections), the minimum flow calibration value is 4.4 (.22 x 20 = 4.4). The system will not apply at a rate lower than this value when spraying in AUTO.

ENTERING MINIMUM FLOW AND PRESSURE VALUES

The “CAL” button is used to toggle between minimum flow and minimum pressure. While in minimum flow, the console indicator will read “CAL”. While in minimum pressure, the console indicator will NOT read “CAL”.

NOTE: Entering these values will determine system control type (flow/pressure/hybrid). See Control chart at right.

To enter minimum flow, use the “+” or “-” button to adjust the displayed value to the calculated minimum flow rate value for the nozzles used (rotary dial in “FLOW RATE” position).

To enter minimum pressure, use the “+” or “-” button to adjust the displayed value to the recommended minimum pressure for the nozzles used.

APPLICATION NOTE: In certain situations, your ground speed may be slow enough to result in over-application. In other words, based on ground speed, the actual flow rate has dropped to the calibrated minimum flow rate.

If you are using a pressure sensor, you must null the pressure offset. For details, see “Pressure Offset”, page 38.

The following chart shows which values must be entered for each of the three control types offered in the MT-3405M.

ADJUST RATE: Enter the value for the desired amount of

change in gallons per acre to be used for making on-the-go rate adjustments when op er at ing in AUTO.

For example, if a value “1.0” is entered, you will be able to increase and decrease your application rate in one-gallon+ increments during operation in AUTO. To disable this feature, simply enter “.0” for a val ue.

TARGET RATE: Enter the value for the desired

target application rate in gallons per acre+. This is the appli ca tion rate that the control console will lock onto when operating in AUTO.

EXITING CALIBRATION: Upon completion of the calibra-

tion process, exit calibration by pressing and holding the CAL button until the RED warning light stops flashing (ap proxi mate ly three sec onds). Basic cal i bra tion is now com plete. BEFORE beginning application, confirm that the system is set up to do the job that you want it to. Please refer to Pre-Field

System Checkout on pages 35 - 36 to confirm cal i bra tion settings, nozzle selec tion and overall system per for mance.

TEST SPEED: Enter the value to be used for simulating

speed for perform ing PreField System Checkout. The console will use this speed for simulating spraying operations. The test speed value is only used while in calibration mode. Once CAL is exited, the Test Speed value is reset to zero. DO

NOT ENTER A TEST SPEED UNTIL ALL OTHER VALUES ARE PROPERLY ADJUSTED. Please refer to Pre-Field System

Fine-Tuning Speed/Distance Calibration Val ue

This procedure is used to verify the calibration of the system. In order to achieve accurate mea sure ments, each step in this ne tun ing procedure should be per formed as pre cise ly as possible.

PREPARATION

Once the system is fully installed and calibrated, se lect a • straight tract of ground that is similar to your ac tu al field conditions and as level as pos si ble.

NOTE: Us ing a course with a different ground surface, such as a hard-surface road, will re sult in differ ent read ings than exact field con di tions.

Measure a distance of 1000 feet. Clear ly mark the • beginning and end points with flags or some thing highly visible to the operator.

PROCEDURE

With the console turned ON, place the Run/Hold switch 1. in the HOLD position. The display will read HOLD. Turn the ro ta ry dial to the “DIS TANCE” po si tion. Be sure the dis play shows 0. If not, reset the distance counter by press ing and hold ing “RE SET” until the display automat ical ly re turns to 0 (ap prox i mate ly three seconds).

You are now ready to drive the measured course. Pick 2. a location on the vehicle to use as a marker for starting and stopping the distance counting function (door han dle, mirror, step, etc.). You should begin driving the course well ahead of the starting flag and drive past the end ing flag, us ing the Run/Hold switch to start and stop the count ing function. It is not rec om mend ed to start from a dead stop at the starting flag and stop at the ending flag.

Place the Run/Hold switch in RUN when the marker on the 3. vehicle passes the starting flag to ac ti vate the distance count ing func tion. The con sole dis play numbers will in crease, adding to the dis tance total as you drive. Drive the pre-mea sured course. Place the Run/Hold switch in HOLD when the mark er on the vehi cle passes the ending flag. This stops the distance count ing function. The console dis play should read “HOLD”. See Illustration 28. Stop the ve hi cle in a lev el and safe area and continue with this procedure.

With the rotary dial still at DISTANCE (CIRC), press and 4. hold the “CAL” key for three seconds. Once the con sole is in “CAL,” the display will alternate be tween the circumfer ence value and the distance measured at about three-second intervals. (When the word “CAL” appears, the num ber dis played is the wheel circumference (CIRC) value. When “CAL” does not appear, this is the dis tance value.) See Illustration 28.

When the display shows distance (“CAL” is not 5. displayed), ver i fy wheth er the number displayed is the ex act dis tance you drove (with in “+” or “-” 2 %). If not, while the display shows distance, press the “+” or “-” keys to ad just the fig ure to match the dis tance you ac tu al ly drove. If the display reads too high, use the “-” key to lower the dis played value. If the display reads too low, use the “+” key to raise the displayed value.

When the number shown on the display match es (as 6. closely as possible) the ac tu al dis tance driv en, you have arrived at the cor rect cal i bra tion val ue. If you can not adjust the displayed distance to exactly match the actual dis tance driven, adjust the figure as close as possible to the actual distance. Then exit “CAL” by pressing “CAL” for three seconds.

NOTE: If you let go of the “+” and “-” keys while you are adjust ing the distance value, the console will wait to make sure you are finished. After 64 sec onds, the dis play will start al ter nat ing be tween the dis tance and wheel circumference (CIRC) values again. Make sure you know which value you are adjusting.

The speed sen sor is now calibrated. To verify proper calibration, repeat the procedure a sec ond time. Write down the new wheel cir cum fer ence (CIRC) number and keep it in a safe place. If the cal i bra tion values are ever accidentally changed, you can simply re-en ter this num ber.

Fine-Tuning Flowmeter Calibration

This procedure is used to verify and ne-tune the owmeter calibration. Every owmeter is calibrated with water at the factory and stamped with a calibration val ue. Enter that value as a starting point and use this pro ce dure to ne-tune that value for your specic in stal la tion and spray ing application (please refer to En ter ing Flow me ter Calibration Value, page 27). This procedure should be repeat ed each time a new solution is being applied (dierent so lu tions will have dierent spe ci c gravities and di er ent ow char ac teris tics) or when the owmeter installa tion has been altered.

PROCEDURE

Put enough water in the sprayer tank to perform this 1. test. (Preferably 100 gallons or more. The larg er the

volume of water used, the more accurate the calibration will be).

Start sprayer pump and turn on booms. Run enough 2. water to purge all air from lines. Turn off booms but leave pump running.

Turn console rotary selector to the TOTAL FLOW position. 3. Press and hold the RESET button until the display reads 0 (about 3 seconds).

Turn on all booms, place the Run/Hold switch in RUN, 4. and run a known amount* of water (preferably 100 gallons or more).

Place the Run/Hold switch in HOLD to turn off booms. 5. Compare the console’s TOTAL FLOW reading with the known amount of water run. See Illustration 29. If the two amounts are within two per cent, no fine tuning is required and you may exit cal i bra tion. If the two amounts are more than two or three percent dif fer ent, con tin ue with the next step.

With the console still in the TOTAL FLOW position, 6. enter calibration (console in HOLD, hold CAL until red light comes on; about three seconds). The dis play will alternate (at about three second intervals) between the flow me ter calibration value and the TOTAL FLOW value.

(To tell which is which, watch for the word “CAL” on display. It will be present with the flowmeter calibration value but not with the TOTAL FLOW value).

When the TOTAL FLOW value is displayed, use the “+” 7. or “-” button to adjust the value to match the amount of water run.

NOTE: Once a value has been selected for ad justment, the display will stop alternating between the two values. This allows you to “fine tune” the value se lect ed. After 64 seconds of neither “+” nor “-” being pressed, alternations will resume. Turning the rotary selector away from, then back to the desired position will also cause alternations to resume.

Once the display again begins alternating, you will 8. notice that the flowmeter calibration value has changed. If the TOTAL FLOW value is correct, write down the new flowmeter calibration value. This is your “fine tuned” calibration value, keep it for future reference.

Exit calibration by holding “CAL” until the console’s red 9. light goes out (about three seconds).

* The most accurate method to measure the volume of

water run is to place a container under EVERY nozzle and add together the amount from each nozzle. This assures that 100 percent of the water is collected and that all nozzles are spraying equally. It is important to perform this pro ce dure at a flow rate similar to that which will be used in the field. It is also possible to disconnect the main boom line and run it to a large measuring container but a valve must be installed and properly adjusted to simulate actual field conditions.

“Special” Calibration

Entering “Special” Calibration

The MT-3405 M system has two control functions which are preset at the factory (See Standard Factory-Loaded Calibration Values chart on page 31). In some cases, however, it may be necessary to change one or both of these settings to enhance performance or meet special requirements. In order to make these changes, you must enter “Special Calibration.” To enter this mode:

With the 1. RUN/HOLD switch in HOLD, turn the power switch OFF.

Turn the rotary dial to the SPEED position.2.

Press and hold the Calibration (“CAL”) button while 3. turning the power switch ON.

Press and hold

during power up.

Servo Polarity

This position is used to designate whether the servo valve (control valve) has been installed in a bypass line (bP) or in the main supply line going to the flowmeter and boom shutoff valves (IL). Use the “+” switch to toggle between these two options (the rotary dial must be in the SPEED position).

The console is programmed at the factory for a bypass (bP) system. See Illustration 30. When the system is used in conjunction with a Micro-Trak NH3 control panel, always select “bP” for the servo polarity.

Valve Type

This position is used to designate what type of boom shut-off valve is installed in the system. Use the “+” switch to select “SOL” for solenoid valves, or “bALL” for ball valves. (The rotary dial must be in the APP. RATE position, and the jumper cover on the back of the console must be properly selected; if cover is on, solenoid is selected, if cover is off, ball is selected).

Illustration 30

Press to toggle

between options.

Illustration 31

The console is programmed at the factory for solenoid (SOL) valves. See Illustration 31.

NOTE: The ball valve selection is for use only with valves that require voltage reversing.

Test Speed

Test Speed is a built-in ground speed simulator that is used in performing “Pre-field” checks. When a typical operating speed is entered, the MT-3405M will respond as if you were actually driving that speed. It allows you to simulate your spraying application with plain water, while remaining stationary, to make certain that all of the equipment is operating properly and that your sprayer can actually perform the intended application.

Test speed is cancelled by exiting CAL. Test speed will not accumulate Distance or Area measurements. Please refer to

Pre-Field System Checkout on the next page.

Pre-Field System Checkout

Pre-Field Sys tem Checkout

Before beginning actual spraying, perform the following “Pre-field” procedure to ensure that your valve settings, nozzle selection and desired speed range will allow the MT-3405M to provide the required application control. This procedure should be repeated for each new nozzle se lec tion and/or application rate. By performing all of the steps listed below, your system will be set up to allow the MT-3405M to perform at optimum level. Fill your sprayer tank with clean water. DO NOT use chemicals until the entire sys tem is completely checked out and operating properly.

NOTE: Most nozzles will maintain a good pattern over a maximum speed range of two to one. (For example, if your maximum speed is 12, your minimum speed shouldn’t go below 6.)

Pre-field System Checkout is a procedure performed while the console is in the CAL mode. The Red WARNING light will be lit during the procedure and “CAL” on the display will be flashing.

Completely open range adjust valve (if installed), ag i-1. ta tion valve (if installed) and throttle valve (must be installed).

NOTE: Pressure relief valve and diaphragm (positive displacement) pump users should refer to Plumbing Guidelines on pages 40-41.

Start vehicle and pump, bring the engine up to normal 2. operating RPM.

Enter MAXIMUM application TEST SPEED into con sole. 3. With console in HOLD, enter calibration mode. Push and hold (CAL) buttons. CAL will appear on display and red light will be on. Turn rotary switch to TEST SPEED position. Use “+” or “-” button to enter maximum application speed. Do not exit cal i bra tion mode. CAL will flash indicating TEST SPEED preference mode.

Select manual “MAN” control mode, turn all boom 4. switches to ON position and put Run/Hold switch in RUN position.

Turn rotary switch to APP. RATE position and hold “+” 5. button for approximately 30 seconds to completely close the servo valve (control valve). (Minimum by pass allowed - maximum flow output to booms.)

Adjust agitation valve for desired agitation. If range 6. valve is installed, adjust range valve until display reads 20% higher than the desired application rate.

CAN’T GET THERE?

If you can’t get to the desired ap pli ca tion rate, you may need a different pump, or mod i fi ca tions to your plumbing configuration. Please refer to Trou ble shoot ing Plumbing.

Slowly close the throttle valve until the display reads 1. slightly higher (5% to 10%) than the desired ap pli ca tion rate. If the throttle valve is more than two-thirds closed,

install range valve and perform pre-field again. Now is a good time to confirm that GPA, GPM, MPH, 2. WIDTH and PSI all coincide with the nozzle man u fac turer’s charts. PSI may be slightly higher than indicated by the charts due to pressure drop across the boom valves, nozzle diaphragm check valves, nozzle screens, etc.

Enter MINIMUM application TEST SPEED into con sole. 3. Turn rotary switch to TEST SPEED position. Use the “+” or “-” button to enter minimum application speed. Do not exit calibration mode. (Remember, the minimum

application speed is not normally less than half of the maximum application speed).

Put Run/Hold switch in RUN position4. (make certain system is in Manual mode), turn rotary switch to APP.

RATE position and hold “-” button for approximately 30 seconds to completely open the servo valve (control valve). (Maximum bypass al lowed - min i mum flow output to booms). The display should now read less than the desired application rate.

It is not normally a problem if the application rate goes 5. all the way to zero when holding the “-” button for 30 sec onds, as long as it goes back up when the “+” but ton is held.

CAN’T GET THERE?

If holding the “-” button does not get the application rate to go below the desired ap pli ca tion rate, please refer to

Troubleshooting Plumbing.

Enter nominal application TEST SPEED into con sole. Put 1. the Run/Hold switch in HOLD. Turn rotary switch to TEST SPEED position. Use the “+” or “-” button to enter target application speed. Do not exit calibration mode.

Select automatic (“AUTO”) control mode, put Run/Hold 2. switch in RUN position and turn rotary switch to APP. RATE position. The console should take control and lock-on to your calibrated target application rate.

If you calibrated your ADJUST RATE to zero (.0), dis re gard 3. the next two steps.

Press the “+” button and release. The display will 4. momentarily show the new target rate (target rate + ad just rate) and then lock on to that rate.

Press the “-” button and release. The display will mo men-5. tari ly show the new target rate (target rate — ad just rate) and then lock on to that rate.

If the application rate was correctly displayed dur ing 6. man ual (“MAN”) control mode, but registered too high in automatic (“AUTO”) control mode, the calibration val ue for MIN FLOW is set too high.

At this point, the Pre-Field System Check-Out is complete. TEST SPEED will automatically cancel when you exit the CAL mode or when power to the console is turned OFF.

This button will switch the control status of the system from fully automatic to manual control. Each press of the button will change the status. The display will show “AUTO” when automatic control mode is active and “MAN” when manual control mode is active.

CAL BUTTON

This button allows you to enter and exit calibration mode. Pressing and holding the CAL button for approximately three seconds will put the console in calibration mode. The display will read “CAL” and the RED warning light will be illuminated. Pressing and holding the CAL button again for approximately three seconds will exit calibration mode and return the console to normal operating mode. The display will no longer read “CAL” and the RED warning light will turn OFF.

Illustration 32

Turn rotary dial to display desired readout.

“+” AND “” BUTTONS

These buttons are used to enter and adjust calibration values when calibrating the system. During normal operation, when automatic (“AUTO”) control mode is active and the rotary dial is set to APP. RATE, each press of the “+” and/or “-” buttons will increase and/or decrease the target application rate by the amount of the calibrated adjust rate.

During normal operation, when manual (“MAN”) control mode is active and the Run/Hold switch is in the RUN position, pressing the “+” or “-” button will increase or decrease the application rate by opening and closing the servo valve (control valve).

During normal operation, when either automatic or manual mode is active, the Run/Hold switch is in the HOLD position and the rotary switch is turned to FLOW RATE, pressing the “+” or “-” button will increase or decrease the flow rate for setting the proper agitation flow rate, without having the boom valves turned on, by opening and closing the servo valve (control valve).

During normal operation, when either automatic or manual mode is active, pressing and holding the RESET (“-”) button will reset the TOTAL AREA, SUB AREA, DISTANCE or TOTAL FLOW counter (the rotary dial must be turned to

one of those counters for the reset function to be active).

Please refer to Resetting System Counters for more details. The reset function is not active when the Run/Hold switch is

in the RUN position or the console is in calibration mode.

Operation (cont)

Rotary Switches, OTG and Warning Light

TOTAL AREA

Displays the acres covered since the counter was last reset to zero. This counter does not accumulate area when the console is in HOLD or if all boom switches are turned OFF. This counter may be reset to zero independent of other system counters.

SPEED

Displays the ground speed in miles per hour.

APP. RATE

Displays the actual number of gallons per acre being applied. When the MT-3405M is used in conjunction with a MicroTrak NH3 control kit, the console display will read pounds of actual “N” per acre being applied.

PRESSURE

Displays the liquid pressure for the current application.

SUB AREA

DISTANCE

Displays the feet driven since the counter was last reset to zero. This counter does not accumulate when the console is in HOLD. This counter may be reset to zero independent of other system counters.

TOTAL FLOW

Displays the total gallons applied since the counter was last reset to zero. When the MT-3405M is used in conjunction with a Micro-Trak NH3 control kit, the console display will read total pounds of actual “N” applied since the counter was last reset. This counter may be reset to zero independent of other system counters.

FLOW RATE

Displays the actual gallons per minute being applied. When the MT-3405M is used in conjunction with a Micro-Trak NH3 control kit, the console display will read total pounds of actual “N” per minute being applied.

ONTHEGO “DELTA” RATE ADJUSTMENTS ADJUST RATE

The calibrated target rate in gallons per acre represents the amount of solution that you typically want to apply. However, under certain conditions, you may want to increase or decrease this rate. This “DELTA” feature allows you to easily make on-the-go rate adjustments by simply using the “+” and “-” buttons. Each press of a button changes the calibrated target rate by the amount of calibrated adjust rate.

To use the “DELTA” feature, the console must have automatic “AUTO” mode active and the rotary dial must be set to the APP. RATE position.

EXAMPLE

Adjust Rate = 1.0 and Target Rate = 10.0

With AUTO selected and the rotary selector turned to APP. RATE, pressing the “+” key once will increase the target rate from 10.0 to 11.0. The display will momentarily show the new target rate of 11.0 and then show the actual application rate. Pressing the “-” key once will decrease the target from 11.0 to

10.0. The display will momentarily show the new target rate of 10.0 and then show the actual application rate.

NOTE: When you “DELTA” the target rate, the display will momentarily show you the new target rate (approximately two seconds) and then resume showing the actual application rate. The new target rate is maintained until further adjustments are made using the “DELTA” feature, the console is turned off, or calibration changes occur.

Operation (cont)

Version/Hour Display on Start-up

On start-up, the MT-3405M console briefly allows the operator to view the software version that is programmed into the console, and the amount of operating hours logged. For approximately one second the display will show the software version (“1101” refers to version 1.1.01). See Illustration 33. Then, for approximately two seconds, the display will show the operating hours that are logged on the console (in 0.1hour increments). See Illustration 34. These settings cannot be cleared by the operator.

Resetting System Counters

The TOTAL AREA, SUB AREA, DISTANCE and TOTAL FLOW counters maintain a running count during operation regardless of the position of the rotary dial. When any of these counters reach their maximum capacity, or when you want to start a new count, the value in the register may be reset to zero by performing the following routine. Counters may be reset independently of each other.

Place the Run/Hold switch in the HOLD position.1.

Turn the rotary dial to the counter position to be reset.2.

Press and hold the RESET button until the display reads 3. zero.

Release the RESET button and resume normal operation. 4.

See Illustrations 35.

Pressure Offset

If your system is set-up to run in “Pressure-only” or “Hybrid” mode (see Control Chart on page 29), you must null the pressure offset. Until the pressure offset is nulled, the pressure display will be blank.

To null the pressure sensor:

Place the 1. RUN/HOLD switch in HOLD. T2. urn the rotary dial to PRESSURE. Press and hold the “-” switch for three seconds. A “0” 3.

should show on the display.

NOTE: The pressure offset can be re-nulled if a new sensor is installed, or at any other time, but the display cannot be blanked once it is set. (In other words, if the sensor is removed, the pressure display will still show a value, not blank.)

Troubleshooting

General

All MT-3405M consoles, flowmeters and servo valves are tested prior to packaging, so unless there has been damage in shipment you can be confident that everything will be operational when you receive it.

However, if you do encounter a problem that appears to be related to equipment failure, please do not open the console. Your system is protected by a warranty, and Micro-Trak will gladly correct any defect.

Many problems are the result of mistakes in installation or operation. Before returning any parts for service, carefully check your installation and review the operating instructions. For easy-to-follow guidelines, refer to the troubleshooting section which follows.

CONSOLE APPEARS DEAD

Using your test light, check for 12 volts at the power source. Also check for damaged power cable, blown fuses or reversed terminals. (Console requires 12 volts for proper operation).

SPEED IS ALWAYS ZERO OR ERRATIC

Check for properly calibrated wheel circumference.

Review speed sensor installation. Check for proper mounting, alignment and spacing of speed sensor in relationship to magnet assembly. Make sure magnet polarities are alternated. Also check cable for breaks or incomplete connection.

For more suggestions on solutions to speed problems, see Hall-effect inputs and console inputs on page 38.

AREA COUNT IS INACCURATE

Implement width or wheel circumference was measured incorrectly or programmed incorrectly. Go back through the original procedures, make changes, and test for acre (hectare) count again. Verify accuracy with formula:

Acres = Distance x Width in feet/43560

Hectares = Distance x Width in meters/10,000

DISTANCE COUNT IS INACCURATE

Wheel circumference was incorrectly measured or entered. Review calibration, readjust and test.

NO READOUT OF GALLONS LITERS, OR GALLONS LITERS PER MINUTE

Check to see that the sprayer pump and equipment are operating properly. If liquid is moving through the line, check the flow sensor to be sure it is screwed all the way into the flowmeter.

Check to see that a FLOW CAL number has been entered. Also check cable for breaks or incomplete connection.

If the flowmeter is new or has not been used for a long period of time, the turbine may be sticky. Flushing the system out with water should make the turbine spin freely.

Flow rate may be too low to register a reading, or foreign material may be lodged in the flowmeter.

TOTAL LIQUID USED IS INACCURATE

This may result from an incorrectly-entered “FLOW CAL” value. Check the number stamped on the flowmeter tag, and be sure this is entered in the console’s “FLOW CAL” position. If the meter has been used for some time, wear may have changed the Flow Cal value. See Fine-Tuning Flowmeter

Calibration on page 30.

Check the mounting position of the flowmeter. With lower flow rates, the meter should be mounted vertically. Also check to see that the flow sensor is screwed all the way into the flowmeter.

Other causes may be inaccurate sprayer tank markings, a flow rate too low to register, or foreign material lodged in the flowmeter.

6553.5 MESSAGE DISPLAYED IN RATE MODE

If this number appears when your equipment is standing still, it indicates that the boom valves are open or not completely closed and liquid is passing through the system.

NOTE: 6553.5 may also temporarily appear when valves are closed if liquid is sloshing back and forth through the flowmeter, or if a portion of the line drains out. In this case, no corrective action is required.

If this message appears when you are in motion with the sprayer on, it indicates that speed sensor impulses have been lost.

“NONET” MESSAGE DISPLAYED

This message appears anytime the console and the module have lost communication. Check the 4-pin cable and connectors for loose connection or damage.

EXCEPTION: If local speed is still connected, the bottom four positions on the rotary dial will read “NONET”, but the “SPEED”, “TOTAL AREA”, “SUB AREA” and “DISTANCE” positions will display normal working data.

CONSOLE IS ERRATIC IN OPERATION

If you have a two-way radio, it may be mounted too close to the console. Keep all MT-3405M cables away from the radio, its antenna and power cable.

Ignition wires may be causing the console to malfunction. Keep MT-3405M cables away from ignition wires, or install ignition suppressor.

Reroute all cables away from electric solenoids, air conditioning clutches and similar equipment.

“BAD CAL” MESSAGE DISPLAYED

This message appears upon power-up if the console detects a corruption in calibration settings since the last power-up. If this occurs, all calibration settings should be verified. To clear this message, simply press the “CAL” button.

DISPLAYED MEASUREMENTS DO NOT MAKE SENSE

The console may be in the incorrect measurement mode (English or Metric). See page 24 for instructions.

DISPLAY READS “OFL”

DISTANCE, TOTAL AREA, SUB AREA and TOTAL FLOW will read OFL when they have exceeded their maximum count. Reset to zero to resume counting.

Troubleshooting (cont)

Checking Individual Components

The only way to field test a console is to con nect it to a harness on a vehicle with a known working console or install it on an E-POP (Elec tron ic Point of Purchase) dis play stand.

HARNESS

The harness can be checked using an ohm me ter or continuity tester. The main wiring diagram shows the pin-out of all connectors. See page 41 for wiring diagram.

ELECTRICAL INTERFERENCE

Erratic operation of the system may be the result of electrical interference from ignition wires or inductive loads (electrical clutch, fan, solenoid, etc). Always try to route wires as far away from suspect areas as possible. If problems occur, you may need to relocate the console and/or wiring harness, or install a noise suppressor and/or spark plugs.

POWER

The power cable has a three-pin connector labeled A, B, C. Check between A-C with a volt meter or test light. If there is no pow er, trace cable toward battery look ing for breaks. Also check any fuses or circuit break ers that supply pow er to the console.

ACCESSORY POWER

The speed, flow and run/hold cables all have an ac ces so ry power wire. Check for 12 volts between B (usu al ly white) and C (usually black) of these con nec tors. If power is not present, make sure the ac ces so ry pow er wire is not open or shorted to ground or to another wire. If this wire has a prob lem, the con sole may ex hib it erratic behavior or not function at all.

RUN/HOLD HALLEFFECT SENSOR

The Hall-effect sensor works similar to a reed switch, but requires power in order to function. This particular type of Hall-effect sensor “closes” when near the south pole of a magnet and is otherwise “open”.

NOTE: Improper connection or voltage could damage the Hall-effect sensor.

MAGNETIC HALLEFFECT SPEED AND FLOW SENSORS

The Hall-effect sen sor works similar to a reed switch, but re quires pow er in order to func tion. Also, this par tic ular type of Hall-effect sen sor re quires al ter nat ing magnetic po lar i ties in or der to switch. This means that the north pole of a magnet will “open” the Hall effect and the south pole of a magnet will “close” the Hall effect.

NOTE: Improper connection or voltage could damage the Hall-effect sensor.

Ground pin C (black) and connect clean 12 volts to pin B (white) of the Hall-effect sensor cable. Con nect the positive lead (red) of an ohmmeter or con ti nu ity tester to pin A (red) and the negative lead (black) of the ohmmeter or continuity tester to pin C of the Hall-effect sensor cable.

Holding the tip of the sensor up to the north pole of a magnet should result in a very high re sis tance (in fi nite), while holding the tip of the sensor up to the south pole of a magnet should result in a very low resistance (300 ohms).

TRAKSTAR ULTRASONIC SPEED SENSOR

Make certain that the Trak-Star is emitting a “crackling” sound. If not, check for power between pins A (WHITE wire) and B (BLUE wire) of the adapter cable’s 6-pin connector. Also make certain that the BLUE wire is securely connected to chassis (frame) ground. Check connection for good metalto-metal contact.

If the ground surface that you are traveling over is too smooth (some blacktop and concrete surfaces, especially wet, icy or snow covered), the speed reading may go to zero, be erratic or be slow to respond. If the Trak-Star is making a “crackling” sound and the ground doesn’t appear to be too smooth, try mounting the Trak-Star pointing forward and as far to the front of the vehicle as possible. (Echo interference

problem: See Trak-Star Installation and Operator’s Manual for details).

Ground pin C (black) and connect clean 12 volts to pin B (white) of the Hall-effect sensor cable. Connect the positive lead (red) of an ohmmeter or continuity tester to pin A (red) and the negative lead (black) of the ohmmeter or continuity tester to pin C (black) of the Hall-effect sensor cable.

Holding the tip of the sensor up to the south pole of a magnet should result in a very low resistance (300 ohms). Taking the sensor away from the magnet should result in a very high resistance (infinite).

RUN/HOLD JUMPER DUST COVER

To test for proper continuity on the jumper wire, connect the ohmmeter to the pins of the dust cover with the jumper wire (A & C). There should be continuity - near zero ohms.

Troubleshooting (cont)

C B A

Console Inputs

If there is no response from any of the following tests, refer to the main Wiring Diagram on the next page to locate the next connector in line to ward the con sole and repeat the test at that con nec tor. If there is a response at that connector, the problem may be in the cable between the two connectors

(or the con nec tors themselves).

SPEED INPUT

Turn rotary dial to speed po si tion and dis con nect the speed sensor (yel low tie) from the main harness. Check for 12 volts between pins B (white) and C (black) of the main harness speed cable (yellow tie). Using a clip lead or other jumper wire (such as a paper clip bent in a “U”), several times rap id ly short to geth er pins A (red) and C (black) of the 3-pin connector (See Illustration 36). The console should respond with some speed read ing.

FLOW INPUT

Turn rotary dial to flow rate (not spray rate) and disconnect the flow sen sor (green tie) from the main harness. Check for 12 volts be tween pins B (white) and C (black) of the main harness flow cable (green tie). Using a clip lead or other jumper wire (paper clip bent in a “U”), several times rapidly short together pins A (red) and C (black) of the 3-pin connector (See Illustration 36). The con sole should re spond with some flow rate reading.

Illustration 36

Three-Pin Connector

REMOTE RUN/HOLD INPUT

Disconnect the remote run/hold sensor (or jumper cover) from the main harness. Check for 12 volts between pins B (white) and C (black) of the main harness remote run/hold cable (gray tie). With the consoles Run/hold switch in RUN, place a clip lead or other jumper wire (such as a paper clip bent in a “U”) between pins A (red) and C (black) of the main harness run/hold connector (gray tie) should turn off the “HOLD” indicator on the console display. Removing the jumper should turn on the “HOLD” indicator on the console display.

FLOWMETER

Shaking the Flowmeter end to end should pro duce a “rattling” sound (shaft end play). Blowing in the meter from either end should spin the turbine freely. If the turbine spins freely but the meter will not register flow with a known working sensor, the turbine may be defective. See Appendix D for Flow me ter

Clean ing and Assembly details.

ELECTRIC BOOM VALVES

To configure your system to use 2-wire motorized ball valve shut-offs, remove the jumper cover from the 2-pin connector on the main console harness. See Wiring Diagram on the next page. If you are using solenoid valves, do not remove jumper cover. If 12 volts are present between the two harness wires to valves, but valves will not activate, consult valve manufacturer’s troubleshooting instructions.

SERVO VALVE CONTROL SIGNAL

Flip the power switch to ON, put the console in MANUAL mode, place the Run/Hold switch in the RUN position and turn all boom switches to ON. Using a voltmeter, check from a good frame ground to each of the servo wires on the main harness connector. There should be about six volts on each wire. Holding the “+” button should cause one wire on the three-pin connector to pulse from six toward four volts and the other wire on the three-pin connector to pulse from six toward eight volts. Holding the “-” button should show the opposite results.

SERVO VALVE

The best way to test the servo valve is with a known working console. Flip the power switch to ON, put the console in MANUAL mode, place the Run/Hold switch in the RUN position and turn all the boom switches to ON. With the servo valve connected to the servo valve lead on the main harness, holding the “+” button should close the servo valve and holding the “-” button should open the servo valve

(provided the console has passed the Servo Valve Control Signal test).

NOTE: The opposite should result if calibrated for inline. The servo valve should operate smoothly from fully open to fully closed, in both directions.

You may also use a 9-volt transistor battery. Connecting the battery to each terminal on the servo valve should cause the servo valve to run in one direction. Reversing the battery connections should cause the servo valve to run the other direction. The servo valve should operate smoothly from end to end, in both directions. DO NOT connect 12 volts directly to the servo valve. Damage may result.

PLUMBING

Proper plumbing is a very important factor in obtaining optimal performance from your MT-3405M system. The chart

on page 41 will help you determine what area of the plumbing may be causing your problem. At this point, it is assumed that your plumbing basically matches that of the System Diagram on page 20 and that the servo valve and flowmeter are

known to be installed correctly and functioning properly. In addition, make certain that you have selected and installed the correct spray tips for the application, speed and spray rate that you intend to maintain. Don’t forget the obvious such as leaky fittings and hoses, pinched hoses and plugged or worn nozzles. If you need more detail than the chart

provides, please refer to Plumbing Guidelines on pages 43 and 44.

PRESSURE SENSOR

The only way to field test the pressure sensor is to connect it to a known working console, apply pressure and verify the correct pressure reading on the console display.

The pressure sensor is a 4-20 mA (industry standard).

Plumbing Guidelines

General

In order for your sprayer to function properly, it must be correctly plumbed. The system diagram on page 20

shows the plumbing configuration that works best with the MT-3405M system. This section will explain the purpose

of each component, list some problems it can cause and recommend some possible solutions to those problems.

A word about pressure drops: All hose, valves and fittings (especially elbows) cause undesirable pressure losses. Keep hoses as large as practical. Don’t use longer hoses than necessary. Avoid bends whenever possible. Use as few fittings as possible. Use full port valves or the next larger size valve. Long hoses should be supported to avoid sagging and kinking. Many spray tip manufacturers have charts showing pressure drop for various fittings and hose sizes.

Now let’s break the system diagram into five sections and cover each one separately. The five sections are the pump inlet line, the agitation line, the servo line, the flowmeter (boom) line and the pump itself.

PUMP INLET

The hose connecting the tank to the pump should be at least as large as the pump inlet port. In most cases 1¼” is a good size. The valve in this line is for complete tank shut-off only and should always be fully open during operation. If this hose is too small or the valve is partially closed, you may not be able to reach your high end goals and pump damage could occur.

AGITATION

The size of the agitation line is dependent upon the amount of agitation required which is determined by the size of the tank and the type of chemical being used. In most cases a 1” hose is large enough.

SERVO

On the system diagram, the hose between tee “B” and the servo can usually be ¾” but 1” will also work. The hose between the servo and tee “C” should be at least as large as the servo. If these lines are too small, you may experience little or no pressure adjustment.

PUMP

The pump must have enough capacity to satisfy the agitation, servo and flowmeter sections of the plumbing. To determine if your pump is large enough you must add up the gallons per minute of all three sections. The following example will take you through the steps involved.

EXAMPLE

Let’s say our example sprayer has a 300-gallon tank with a Spraying Systems 6290 SC-8 Jet Agitator. The agitator uses 10.2 GPM at 40 PSI. (Spraying Systems

Catalog 38, page 44).

The sprayer has a 40’, three-section boom. Each section is 160” with four tips at 40” for a total of 12 tips. We plan to put on a 25 GPA at 5 MPH and in some areas of the fields we may want to use the Delta feature and increase our rate to 30 GPA and in other areas decrease to 15 GPA. After checking the tip charts we find that a TK-5 Floodjet has a range of

14.9 to 30 GPA at 5 MPH. According to the charts, to get 30 GPA at 5 MPH with a TK-5, the pressure must be 40 PSI. At 40 PSI a TK-5 will spray 1.0 GPM. So, 12 tips at 1.0 GPM each is a total of 12 GPM.

The specification section of this manual shows that when fully closed, a 1” servo valve at 40 PSI will pass 5 GPM.

Now let’s add everything together.

Agitation 10.2 Spray Tips 12.0 Servo 5.0

27.2 Total GPM

The above addition shows that the system needs 27.2 GPM at 40 PSI. If we add a 10% margin (27.2 x .1 = 2.72 and 27.2 =

29.92), we have about 30 GPM. To be sure we have enough volume, the pump should be able to deliver 30 GPM or more at 40 PSI.

FLOWMETER

The line feeding the flowmeter and the boom shut-off valves should be at least as large as the flowmeter. The size of lines going from the shut-off valves to each boom section depends on the flow rate of each boom.

Plumbing Guidelines (cont)

Valve Purpose and Adjustments

TANK SHUTOFF VALVE

The tank shut-off valve is for convenience only. It allows you to work on the plumbing without draining the tank. It should always be fully open during operation. See Plumbing

Overview Diagram on page 20.

AGITATION SHUTOFF VALVE

The agitation shut-off valve is mostly for convenience. It allows you to work on the plumbing without draining the tank. It should normally be fully open during operation. See

Plumbing Overview Diagram on page 20.

MECHANICAL PRESSURE RELIEF VALVE

The pressure relief valve is used to avoid excessive pressure when the booms are turned off. Start with the pressure relief valve handle screwed most of the way out. Slowly bring pump up to operating RPM (make sure pressure does not go too high). Place the ON/OFF switch on the console in the ON position, place the RUN/HOLD switch in RUN, and turn on boom one. Hold the “+” button for about 30 seconds to fully close the servo valve. Place the console in HOLD. Boom one should shut off. Now slowly screw the pressure relief valve handle in until the desired maximum pressure is obtained. Lock handle in place with locking nut or collar.

NOTE: Spraying Systems 144H DirectoValve has a maximum pressure rating of 100 PSI (7 bar).

RANGE ADJUST VALVE

The range adjust valve is required when the pump is much larger than necessary. When the range valve is opened, some of the liquid will be bypassed around the pump to avoid “overloading” the rest of the system. The setting of the range adjust valve is determined by the throttle valve. Start

with the range valve fully closed and perform the “Pre-field” System Checkout on page 33. If the throttle valve needs to

be more than two thirds closed, open the range adjust valve slightly and perform the “Pre-field” Checkout again. See

Illustration 19 on page 17.

THROTTLE VALVE

The throttle valve limits your high end to maximize servo performance. Start with throttle valve fully open and

perform the “Pre-field” System Checkout on page 33. See Plumbing Overview Diagram on page 20.

EXAMPLE With the throttle fully open and servo fully closed, you

may be able to get 50 GPA at 5 MPH when you only want 25 GPA. If you were to simply open the servo you may be able to get down to 25 GPA, but if your speed should drop to 3 MPH, the servo can’t open any farther and won’t be able to maintain 25 GPA. Therefore, if you leave the servo closed and close the throttle until your high end has dropped from 50 GPA to about 30 GPA, the servo has a greater operating range.

The throttle valve pictured in the system diagram is

a needle valve. A ball valve may be used but is more difficult to adjust and keep adjusted. Do not install a pressure regulator or relief as a throttle valve.

If the throttle is too far closed, PSI may fluctuate greatly in

AUTO.

ELECTRIC RELIEF VALVE

The relief solenoid is intended to insure enough bypass to avoid over-pressuring the system when the boom valves are turned off. See Illustration 21A on page 21.

Care and Maintenance of your MT-3405M

CONSOLE

Store the console in a cool dry location if it will not be used for an extended period of time, such as during the • off-season.

As with any electronic equipment, use care in cleaning so that water or other liquids do not enter the case. •

Thoroughly rinse Flowmeter with clean water, install plastic shipping plugs and keep from freezing.•

PRECAUTIONS

The input pressure on the glass-filled nylon flowmeter FM750 GFN should not exceed 100 PSI (7 bar).•

Do not expose the flowmeter to liquid temperatures exceeding 130 degrees F (55 degrees C).•

Some chemicals may damage the PPS turbine or the nylon body of the flowmeter. If you are in doubt, contact the • chemical manufacturer.

Implement Wheels

Prepare and install magnet clips as shown.1.

Place a magnet at the end of each clip (longest side of 2. magnet should point in the direction of wheel rotation). Place a cable tie (ribbed side toward magnet) around the wheel hub and tighten to secure magnets in place. For large hubs, two or more cable ties can be joined together.

Rigidly mount sensor mounting bracket to the wheel 3. assembly. Cut or bend “L” bracket as required for proper positioning of sensor.

Install sensor, adjust to correct spacing, and secure with 4. 3/8” locking nuts. See Illustration at right.

Front Tractor Wheel

When possible, attach magnet clips as shown for 1. implement wheel. This may require substituting longer lug bolts and securing clips with nuts. Magnet clips may also be secured by drilling and tapping holes for smaller bolts directly into the hub, or with an adhesive.

Mount the speed sensor bracket to a part of the wheel 2. assembly that does not change position to the hub when the wheels are turned. If the “L” bracket provided cannot be bent and mounted to properly position the sensor, make a bracket similar to the one shown at right.

Insert sensor, adjust spacing and secure with 3/8” locking 3. nuts.

ATV Wheels

Two mounting examples are illustrated.

Using one cable tie (ribbed side toward magnets) secure 1. two magnets to the wheel hub so they are exactly opposite each other. Alternate the magnets’ polarities. The long dimension of the magnet must wrap around the hub or shaft.

Cut and bend sensor mounting bracket as needed and 2. rigidly mount.

Insert sensor, adjust spacing and secure with 3/8” locking 3. nuts.

NOTE: Make sure valve stem cannot make contact with sensor or bracket.

Optional

NOTE: This is an optional method generally used on pickups or custom vehicles. It may also be nec essary on any other vehicles where ac cess to the wheels is lim it ed. This in stal la tion requires a “Circ” Calibration

procedure, on page 26.

Determine the best location for the magnets on drive shaft according to which is the most practical spot to attach sensor mounting bracket. This position should be no more than 12 inches (.30 meters) behind the front U-joint. For best results, mount “L” bracket to transmission and mount magnets on drive shaft as close to transmission as pos si ble. This will en sure prop er alignment if drive train shifts under heavy loading.

Two magnets are required for proper Hall-effect speed sensor operation. Position them exactly opposite each other (180 de grees apart). The polarity (north and south poles) detect ed by the Hall-effect speed sen sor must alternate as the shaft is turned. The magnets provided by Micro-Trak are marked with a punched dashed line on the SOUTH pole side of the magnet.

Mounting on Drive Shaft

Attach magnets onto drive shaft, one NORTH pole side • out and the other SOUTH (dashed) pole side out, by wrapping ca ble tie around shaft and magnets. Position each mag net so that its longest dimension moves in the di rec tion of rotation. Pull cable tie tight and trim off excess. An adjust able, non-magnetic (stain less steel) band clamp may also be substituted.

Attach sensor bracket to vehicle transmission • with bolts, lockwashers and nuts provided. See Illustration below. Use either the short or long end of the brack et as a base. (Allow enough room be tween the bracket and the magnets so that when prop erly spaced, the tip of the sensor will extend 1/4” [7mm] or more be yond the lock ing nut.)

Turn one locking nut onto threaded sensor and in sert • sensor into large hole selected on mount ing brack et. Turn on remaining locking nut. Set sensor to proper distance from magnets (1/4” to 1/2”, or 6mm to 13mm). When distance is set, tight en nuts to lock sensor in place.

Secure sensor cable to frame with cable ties. Place first • tie as close to sensor assembly as possible.

NOTE: If you are using more than two magnets, please follow the directions on page 12.

12-Volt Servo Valve (Control Valve) Calibration

Your MT-3405M is factory calibrated to operate the standard Micro-Trak Electric Servo Valve (8-volt). The system is also capable of using standard 12-volt control valves in place of the Micro-Trak Electric Servo Valve. However, the factory setting will not allow standard 12-volt control valves to function at peak performance. You need to activate the special 12-volt control driver to ensure optimal performance.

When the system will be used in English mode, the rotary selector MUST be turned to TOTAL AREA when activating the 12-volt servo mode.

When the system will be used in Metric mode, the rotary selector MUST be turned to SUB AREA when activating the 12-volt servo mode.

When the system will be used in Turf mode, the rotary selector MUST be turned to DISTANCE when activating the 12-volt servo mode.

Activating the 12-volt servo mode also defaults all of your calibration settings to the factory settings. BEFORE activating the 12-volt servo mode, write down ALL of your calibration settings. Then you can simply re-enter them after activating the 12-volt servo mode.

To activate the 12-volt servo mode, turn the power switch to OFF. Turn the rotary selector to the appropriate position

(TOTAL AREA for English mode, SUB AREA for Metric mode, or DISTANCE for Turf mode). Press and hold the CAL, RESET and

“+” buttons on the front panel and while continuing to hold the three buttons switch the power to ON. Once powered up, release the three buttons. A “v” will be illuminated on the display to indicate that the 12-volt servo mode is active. To “lock-in” the 12-volt servo mode, you must enter calibration. Press and hold the CAL button until “CAL” lights on the display and the RED warning light is flashing (approximately three seconds). The console is now in calibration mode and the 12-volt servo mode is “locked-in”. Because this procedure also restores factory calibration values, you must re-calibrate the system for your application. Adjust all necessary calibration values and exit calibration by pressing and holding the CAL button until the RED light stops flashing (approximately three seconds). The console will remain in the 12-volt servo mode, even after power is cycled.

Turn rotary dial to “TOTAL AREA”

to activate English mode.

Press and hold

during power-up

Turn rotary dial

to “DISTANCE” to

activate Turf mode.

To return to 8-volt mode, repeat the above procedure only holding the “CAL” and “—” (not“+”). This will also select English/Metric mode, and restore factory calibration values.

NOTE: Do not operate system with Micro-Trak Electric Servo Valve installed when the 12-volt servo mode is activated. Damage to the servo valve will result.

OPERATIONAL NOTE: Many of the 12-volt control valves on the market operate very slowly from fully closed to fully open. The MT-3405M may operate sluggishly or be slow in control response time. For optimal performance, the control valve should be installed in a return line with a throttling valve installed.

“v” indicates 12-volt control valve driver.

Flowmeter Cleaning and Assembly

NOTE: Opening the flowmeter will void the flowmeter calibration value assigned to your unit. However, you may need to take the flowmeter apart for periodic cleaning or to remove an obstruction.

If you can shake the flowmeter from end-to-end to produce a “rattling” sound (shaft-end play), or if you can blow into the meter from either end and cause the turbine to spin freely, your flowmeter does not need cleaning. If you cannot hear the “rattling” sound or get the turbine to spin freely, your flowmeter needs to be cleaned. See Illustrations for

reassembly instructions.

OPENING FLOWMETER

Cut the calibration tag retaining wire. Remove the screws and disassemble the flowmeter. DO NOT attempt to remove the sleeve bearings from the flowmeter housing.

Use warm water and if necessary, a mild detergent and a soft bristle brush to clean all parts. DO NOT use solvents or diesel fuel to clean the flowmeter. A magnet works well for removing fine metallic particles from the turbine.

Inspect all parts. Check for excessive bearing or shaft wear. The shaft will wear shorter until the turbine drags on the housing. The illustration below shows you what a new shaft looks like.

When the shaft is worn to the point of drag, the turbine must be replaced.

NOTE: The turbines have magnets built into the fins. There are no visible magnets.

On a flat surface, place each housing half on end. Set and spin the turbine in each half. It should spin freely. If it does not spin freely, remove the turbine, wipe the shaft and try again. If is still does not spin freely, the shaft or bearings may have excessive wear. (Service may be necessary.)

ASSEMBLING FLOWMETER

Place turbine in non-sensor housing. Coat O-ring with silicon grease and position O-ring on housing. (O-ring may be reused a few times, but will eventually need to be replaced.) Carefully set turbine in place. Drop all screws into holes. Hold nuts in place and finger-tighten screws. Making sure O-ring is still properly aligned, evenly tighten all screws. Attach tag.

After assembly, shaking flowmeter end-to-end should produce a “rattling” sound (shaft end play). Blowing into the meter from either end should cause the turbine to spin freely. If the turbine only spins from one direction, install the flowmeter so that the liquid flows in that direction (service may be required).

For maximum accuracy the flowmeter should be mounted in a vertical position. Accuracy of flowmeter readings cannot be guaranteed for flow rates below two gallons per minute. Recalibration is required before field operation.
