Power is connected directly to the battery. The MT-9000 Series has an ON/OFF switch on the console to turn the power off when the system is not being used. 20.0 Amp in-line Fuse Required Hot (White) C B A Ground 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 2. Make sure there is good metal-to-metal contact. Route the power cable from the console to the battery. Cut excess length. In routing cable to battery, avoid areas where the cable may be subjected to abrasion or excessive heat. Install the in-line fuse provided with the kit as illustrated, on the white wire, to protect the circuit. Connect the WHITE wire (hot) to the positive battery terminal. Attach the BLACK wire (ground) to a screw or bolt on the equipment frame. See Illustration 2. Be sure there is good metal-to-metal con tact. Chassis Ground (black) NOTE: For Negative Ground Systems Only Your MT-9000 Series is equipped with an electronic memory which does not require a constant supply of power to retain daily totals or calibration values. The advantage with this type of memory is that it conserves battery power and will not discharge the vehicle’s battery when equipment is not in use. 8 Installation (cont) Locate the Following Parts Speed Sensor Installation • • • • • Please Note: If you have purchased a Trak-Star speed sensor, disregard the following section on magnetic speed sensors and install the Trak-Star as described in the instructions included with the unit. (Please refer to page 12 for additional speed sensor options.) Speed Sensor Cable Mounting “L” Bracket Magnet Clips Magnets Cable Ties S Magnets Illustration 3A Please read the following information about magnet spacing and polarity. The number of magnets that must be used depends on the size of your tire and 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), a minimum of two magnets are required. N Illustration 3B Some installations may require that more than two magnets be installed. To determine the number of magnets required, measure the distance traveled of one revolution of the sensor equipped wheel in inches (meters). Divide that measurement by 20 for English and Turf units, or by .5 for Metric units, and then round up to the nearest even number (always use an even number of magnets). That number will be the minimum number of magnets required for the installation. North 1 6 South If your revolution measurement is 97 inches, dividing that number by 20 gives you a value of 4.85. Rounding 4.85 up to the nearest even number is 6. For this example, the minimum number of magnets required is 6. South North 2 5 North Example in English/Turf units Test magnet should alternately attract and repel. 4 3 South Illustration 3C 1” Minimum Example in Metric units If your revolution measurement is 2.5 meters, dividing that number by .5 gives you a value of 5. Rounding 5 up to the nearest even number is 6. For this example, the minimum number of magnets required is 6. The magnets provided by Micro-Trak are marked with a punched dashed line on the SOUTH pole side of the magnet. See Illustration 3A. NOTE: Refer to Appendix A for optional mounting instructions. 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. 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. To install, mount the first magnet with the SOUTH pole side (dashed line) facing toward the hub or shaft. Mount the second magnet with the NORTH pole side facing toward the hub or shaft. See Illustration 3B. English or Turf (inches) For proper operation, the magnets must be evenly spaced around the wheel or drive shaft. They must have alternating polarities, and the magnets must also be at least 1” apart. See Illustration 3C. Wheel Circumference 40 80 Number of Magnets 2 4 100 200 2 4 120 160 6 8 200 10 Metric (cm) Wheel Circumference Number of Magnets 9 300 400 6 8 500 10 Installation (cont) Drill lug bolt hole and bend to fit hub. Speed Sensor Installation (cont) Magnet Attaching Magnets The magnets are attached to a wheel hub or drive shaft and the speed sensor is mounted directly over the magnet. When the wheel or drive shaft begins turning, a speed impulse is sent to the MT-9000 Series 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 4. Sensor assembly must not be mounted more than 45° from perpendicular Illustration 4 Bracket must be rigidly mounted 45° max 3/8” nuts Sensor (Green body) ¼” to ½” air gap Magnet Connecting the Speed Sensor Cable Sensor identification Chart 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 connector on the main harness. The speed sensor and 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 the flow sensor always connects to the main harness lead with the GREEN tie. See Illustration 5.

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) on the control console pigtail exiting the rear of the console. Using this connection point will disable the connection point on the end of the main harness. For speed sensor installations on implements, it may be more practical to use the speed connector on the end of the main harness. When using this connection point, make certain that the local access connector for speed/distance is mated together. 10-PIN METRI-PACK TOWER Illustration 5 BLUE TIE YELLOW TIE A B C D E F G H J K Installation (cont) Connecting the Run/hold Sensor Cable NOTE: Remote run/hold is NOT recommended for use with NH3 systems. Speed Sensor Options In addition to the standard Hall-effect magnetic speed sensor, the MT-9000 may be interfaced with a variety of other speed sensing equipment. Several options are listed below. 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 Astro II GPS 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 required for proper interface. SEE APPENDIX H FOR LIST OF ADAPTER CABLES FOR RADAR.

Follow these procedures carefully to make sure you are properly prepared before you get to the field. We’ll begin with the Special Calibration section. You will need to go to Special Calibration anytime your system uses a modified set-up. Modifications include: Metric or Turf measurement, Servo type other than a Micro-Trak servo valve, in-line (except NH3) versus by-pass plumbing, ball valves versus solenoid valves. If your system does not use any of these modifications, skip “Special” Calibration and go to Standard Liquid Calibration on pages 29-35. This system is also equipped with a Software Utility package that includes the “Calibration Wizard” program, that allows you to calibrate your system electronically. See the Compact Disc you received with your MT-9000 Series Automatic Rate Controller and the Software Utility Reference Manual. “Special” Calibration Entering “Special” Calibration The MT-9000 Series has a number of control functions which are preset at the factory (See Factory Calibration Chart on page 29). In some cases, however, it may be necessary to change one or more of these settings to enhance performance or meet special operational requirements. To make these changes, you need to enter “Special” Calibration. To enter “Special” Calibration, do the following: Illustration 15 MT-9000 SeRIeS eRROR 1. Turn the power switch OFF.

BOOM WIDTH Display will Read ERROR CAL PSI bar Rate 1 2 3 Gal / 1000 Lbs N / Ac Gal / Ac kg / ha liters / ha meters data inches Setting Working Width In order to accurately measure the number of units applied per acre (hectare), 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 (thousandth of a meter). Min flow: The purpose of this calibration parameter Display will Read is to set the minimum Dial Position recommended flow rate for the flowmeter in the NH3 Kit. Once set, the system MIn. flOW will prevent the actual flow rate from going below the recommended minimum rating, preventing the flowmeter from stalling (turbine stopping). You may set a minimum flow rating for each target rate. ERROR CAL PSI bar Rate 1 2 3 Gal / 1000 Lbs N / Ac Gal / Ac kg / ha liters / ha meters data inches Application Note: In certain situations when applying in AUTO, your ground speed may be slow enough to result in an over-application error. In other words, based on ground speed, the actual flow rate for your application is below the calibrated minimum. Remember, in AUTo, the system will not allow the flow rate to drop below the calibrated minimum. Entering minimum flow values Each target rate has a different settings for minimum flow. Press the RATE 1 button. The lower right portion of the display will be showing the minimum flow value. Use the “+/-” switch to adjust the displayed value (lbs. NH3 per minute) to 10.0. Repeat the procedure for RATE 2 and 3. Enter the same minimum flow values for those target rates. 25 Standard NH3 Calibration (cont) Entering Standard Calibration Values (cont) flowmeter: This position is used to enter the calibration Display will Read number from the flowmeter tag.

When this position is selected, the display will show the wheel circumference value and the distance travelled. Either one may be selected to calibrate for speed and distance measurement. Dial Position Display will Read Distance Traveled ERROR CAL PSI bar NOTE: Because of the difference in wheel-toDISTance drive shaft ratios, 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. Rate 1 2 3 gal / 1000 Lbs N / Ac gal / Ac kg / ha liters / ha meters data inches Distance CAL Factor Refer to Fine-Tuning Speed/Distance Calibration for more detailed information. Determining Wheel Circumference Illustration 18 For the console to calculate the correct speed and measure distance accurately, the circumference of the sensor-equipped wheel must be entered. Determine the circumference of the sensor-mounted wheel, to the nearest tenth of an inch (thousandth of a meter), with the following method: Mark the tire with a piece of chalk and measure distance travelled on the ground for one complete revolution. See Illustration 18. For improved accuracy, it is recommended to perform this function in field conditions, measure several revolutions, and take the average. To determine circumference, measure the distance of one complete wheel revolution and divide by the number of magnets installed. Divide the measured revolution by the number of magnets installed to get your starting wheel circumference calibration value. Once calibration of the system is complete, this number should be fine-tuned for optimum accuracy. Please refer to Fine-Tuning Speed/Distance Calibration Value on page 33. 26 Standard NH3 Calibration (cont) Fine Tuning Speed/Distance Calibration Value 3. P lace the console in MAN when the marker on the vehicle passes the starting flag to activate the distance counting function. The console display numbers will increase, adding to the distance total as you drive. Drive the premeasured course and place the console in HOLD when the marker on the vehicle passes the ending flag to stop the distance counting function. Stop the vehicle in a safe and level area and continue with this procedure. This procedure is used to verify the calibration of the system. In order to achieve accurate measurements, each step in this fine tuning procedure should be performed as precisely as possible. Preparation • O nce the system is fully installed and calibrated, select a straight tract of ground that is similar to your actual field conditions and as level as possible. 4. T oggle the “+/-” switch to adjust the upper display until it matches the actual distance traveled. NOTE: Using a course with a different ground surface, such as a hard-surface road, will result in different readings than exact field conditions. 5. W hen the number shown on the display matches (as closely as possible) the actual distance driven, you have arrived at the correct calibration value. This will also finetune the Distance Cal factor in the lower right display. • M easure a distance of 1000 feet (500 meters). Clearly mark the beginning and end points with flags or something highly visible to the user. To verify proper calibration, repeat the procedure a second time. Write down the new wheel circumference (CIRC) number (lower right display) and keep it in a safe place. If the calibration values are ever accidentally changed, you can simply re-enter this number. Procedure Warning: Turn boom switches OFF to avoid product application during the following procedure. 1. P lace the console in HOLD. The display will read HOLD. Turn the rotary dial to the “Distance” position. Be sure the display shows “0.” If not, reset the distance counter by pressing and holding “Reset” until the display automatically returns to 0 (approximately three seconds). MT-9000 SeRIeS 2. You are now ready to drive the measured course. Pick a location on the vehicle to use as a marker for starting and stopping the distance counting function (e.g. door handle, mirror, step). You should begin to drive the course well ahead of the starting flag and drive past the ending flag, using the Master switch to start and stop the counting function. It is not recommended to start from a dead stop at the starting flag and stop at the ending flag.

This procedure is used to verify and fine-tune the flowmeter calibration. Every flowmeter is calibrated with water at the factory and stamped with a calibration value. Enter the value as a starting point and use this procedure to fine-tune that value for your specific installation and NH3 application (refer to Entering Flowmeter Calibration on page 31. This procedure should be repeated when the flowmeter installation has been altered. 7. Y ou will notice that the flowmeter calibration value has changed.

For example, the MAN position may be used by the user to do things such as spot applications. During normal operation, the console will always display application rate in the upper half of the display, and will always display pressure in the lower left corner of the display (when pressure sensor is installed). The lower right corner of the display is used to show the data that corresponds with the position selected on the rotary dial (top six positions are operational positions). Using the “+/-” switch while in MAN allows the user to control the increase or decrease of flow or pressure as needed. During normal operation, when the Boom One switch is OFF, the console will turn the applicator off, application will stop and acre, gallon and distance counters will stop. For example, when turning on end rows, place the BOOM ONE switch to the OFF position. This disables area and distance counters. For example, in the following illustration, the top half of the display tells the user that Rate 1 is selected and the application rate is 120.0 pounds of “N” per acre. The lower left portion of the display tells the user that the operating pressure is at 54 PSI. And with the rotary dial set to Speed, the lower right portion of the display tells the user that the current ground speed is 4.5 MPH. “+/-” switch The “+/-” switch serves many functions within the system, and can be used within Calibration and Operation (Auto and MAN). Power switch This switch controls 12-volt power to the entire system. In the OFF position, there will be no drain to the vehicle’s electrical system. During normal operation, when automatic (AUTO) control mode is active, Boom One is on, and the rotary dial is not in a calibration position, each toggle of the switch will increase or decrease the target application rate by the amount of the calibrated adjust rate (“Delta”).

When the boom one switch is turned on, the boom shutoff valve should be on. When the boom one switch is turned off, the boom shut-off valve should be off. Additionally, the shut-off valve should not be on if the console’s Master Switch is in HOLD, or in AUTO while speed is zero. auTO Man HOlD Auto/man/hold switch This master switch will change the control status of the system from fully automatic control (“AUTO”), to manual control (“MAN”). During normal operation, when the Auto/ man/hold switch is in AUTO and the Boom One switch is on, and the rotary dial is not in a calibration position, the console adjusts the servo valve to maintain the desired application rate. For example, as speed increases, the servo valve automatically opens in order to maintain the desired application rate. As speed decreases, the servo valve automatically closes to maintain the application rate. 30 Operation (cont) Console Operation (cont) rate buttons tank button While in calibration, the Rate buttons are used to set three separate target rates. To do this, turn the rotary knob to the Target Rate position, press the appropriate rate button, and use the “+/-” keys to enter and adjust to the desired value. test button The Rate buttons serve many functions within the system, and can be used within Calibration and Operation (Auto and MAN). The rate buttons allow you to quickly select an alternative pre-programmed rate. They can be used in several different ways. This button is used during normal operation to check the pounds of NH3 (Kg/NH3) remaining in the tank. With the rotary dial in any of the six operational positions (BLUE and GREEN), pressing and holding this button will enable the upper half of the display to readout the pounds (Kg/NH3) remaining in the tank. By releasing the TANK button, the display will revert back to the application rate. This button is used to enter the Test Speed mode when calibrating the system. This button is NOT for use with anhydrous ammonia application. While in operation, the Rate buttons are used to select which pre-programmed rate you will use during application. For example, Rate 1 could be set at a low-end rate (e.g. 50 lbs. “N”/acre), Rate 2 at a mid-range rate (Target, e.g. 100 lbs. “N”/acre), and Rate 3 a high-end rate (e.g. 150 lbs. “N”/acre). MT-9000 SeRIeS reset button During normal operation, this button is used to reset a counters register to zero. Refer to resetting counters for more information. In standard calibration mode, this button is used to select boom sections for calibration. In special calibration mode, pressing the reset button will exit this mode.

NOTE: FIELD FLOW and FLOWMETER are cleared together. Field Operation In hilly or rough conditions the nurse tank dip tube will not remain submerged, allowing extra vapor in the system. This vapor is too much for the heat exchanger to condense and the system will exhibit erratic operation. If the dip tube remains out of liquid, operation may appear to be normal, but the system is simply metering vapor. If this occurs, you will notice extremely low manifold pressure. Change tanks before the NH3 level is low enough to cause these problems. Always follow accepted safety precautions. Make sure that equipment is in good operating order. Before connecting the tank to the applicator, check the electric shut-off valve for proper operation. After changing tanks or after other periods of long shutdown, operate the system in MAN until the application rate stabilizes. This allows the heat exchanger to reach operating temperature before selecting AUTO. Erratic operation may be experienced if AUTO is selected before operating temperature is reached. In NH3 control systems, location of the frost build-up is an indication of system performance. The MT-9000 Series system will normally have frost on the output side of the servo valve and in some cases, a small amount on the bottom portion of the heat exchanger. Frost before the servo valve indicates excessive pressure drop in the delivery system or restricted vapor lines. Manifold pressure is very important for good distribution of NH3. Use barbed fittings with properly sized orifices or an adjustable manifold to maintain adequate pressure. If manifold back pressure is too low, proper cooling will not be achieved, vapor bubbles will be allowed to enter flowmeter, and readings will be inaccurate. Typical manifold pressure ranges from 15 to 60 PSI/1 to 4.1 bar depending on application rates and ambient temperature. If manifold pressure stops climbing but FLOW RATE continues to climb, vapor bubbles are present. The strainer is a common source of excessive pressure drop and should be cleaned regularly. After completely bleeding the system, remove the large plug and carefully clean the strainer’s screen. Also, periodically check the vapor tubes for obstructions. 32 Troubleshooting General Total NH3 Used is Inaccurate All MT-9000 Series consoles, flowmeters and servo valves are tested prior to packaging, so unless there has been damage in shipment, everything will be operational when you receive it. Note: APP RATE refers to “N” (units of Nitrogen). FLOW RATE, TOTAL and FIELD FLOW refer to NH3 (total product). 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. 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 Flowmeter position. If the meter has been used frequently, wear may have changed the Flow Cal value. See Fine-Tuning Flowmeter Calibration on page 32. 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. Check to see that the flow sensor is screwed all the way into the flowmeter. Other causes may be a flow rate that is too low to register, or foreign material lodged in the flowmeter. Console Appears Dead Using your MT-101 or homemade test light, check for 12 volts at the power source. Also check for damaged power cable or reversed terminals. (Console requires 12 volts for proper operation). Check for blown fuses. 6553.5 Message Displayed in Rate Mode If this number appears when your equipment is standing still, it indicates that the boom valve is open or not completely closed and liquid is passing through the system. Speed is Always Zero or Erratic 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. Check for properly calibrated wheel circumference. Review speed sensor installation. Check for proper mounting, alignment and spacing of speed sensor in relationship to magnets. Make sure magnet polarities are alternated. Also check cable for breaks or incomplete connection. If this message appears when you are in motion with the NH3 kit on, it indicates that speed sensor impulses have been lost. For more suggestions/solutions to speed problems, see Halleffect inputs and console inputs on pages 43-44. Console is Erratic in Operation Area Count is Inaccurate If you have a two-way radio, it may be mounted too close to the console. Keep all MT-9000 Series cables away from the radio, its antenna and power cable. 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 this formula: Ignition wires may be causing the console to malfunction. Keep MT-9000 Series cables away from ignition wires, or install ignition suppressor. Acres = Distance x Width (in feet) / 43560 Distance Count is Inaccurate Wheel circumference was incorrectly measured or entered. Review calibration, readjust and test. Reroute all cables away from electric solenoids, air conditioning clutches and similar equipment. No Readout of Pounds, or Pounds per Minute Displayed Measurements Do Not Make Sense The console may be in the incorrect measurement mode (English, Metric or Turf Units). See page 23 for details. Check to see that all valves and related equipment are operating properly. If material is flowing through the line, check the flow sensor to be sure it is screwed all the way into the flowmeter. Display Reads “OFL” Distance, Total Area, Sub Area, Field Flow and Total Flow will read “OFL” when they have exceeded their maximum count. Reset to zero to resume counting. Check to see that a FLOW CAL number has been entered. Also check cables for breaks or incomplete connections. 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. 33 Troubleshooting (cont) Checking Individual Components Console Trak-Star Ultrasonic Speed Sensor The only way to field test a console is to connect it to a harness on a vehicle with a known working console or install it on an E-POP (Electronic Point-of-Purchase) display stand. Make certain that the Trak-Star is emitting a “crackling” sound. If not, check for power at pins A (white) and B (blue) 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 metal-to-metal contact. Harness The harness can be checked using an ohmmeter or the MT-101 (continuity tester). The main wiring diagram shows the pin-out of all connectors. See page 19. 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.) 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, and C. Check between A-C with a volt meter or test light. If there is no power, trace cable toward battery looking for breaks. Also check any fuses or circuit breakers that supply power to the console. Accessory Power The speed, flow and run/hold cables all have an accessory power wire. Check for 12 volts between B (usually white) and C (usually black) of these connectors. If power is not present, make sure the accessory power wire is not open or shorted to ground or to another wire. If this wire has a problem, the console may exhibit erratic behavior or not function at all. Magnetic Hall-Effect Speed and Flow Sensors Caution: Improper connection or voltage could damage the Hall-effect sensor. The Hall-effect sensor works similar to a reed switch, but requires power in order to function. Also, this particular type of Hall-effect sensor requires alternating magnetic polarities in order 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. The Hall-effect will remain “latched” without the presence of a magnet. 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 to the north pole of a magnet should result in a very high resistance (infinite), while holding the sensor up to the south pole of a magnet should result in a very low resistance (near zero). 34 Troubleshooting (cont) Checking Individual Components (cont) Console Inputs Ball Valves If there is no response from any of the following tests, refer to the main wiring diagram on the page 18 to locate the next connector in line toward the console and repeat the test at that connector. If there is a response at that connector, the problem may be in the cable between the two connectors (or the connectors themselves). If the voltage reverses when switch is thrown, but valve does not run, valve may be defective. Consult your valve manufacturer. Servo Valve Control Signal The servo valve control signal cannot be checked without a load. Connect a known working servo valve or other suitable load (12-volt test light or 100-ohm resistor). Speed Input: Turn the rotary dial to the speed position and disconnect the speed sensor (yellow 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”), rapidly short together pins A (red) and C (black) of the 3-pin connector several times (See Illustration 21). The console should respond with some speed reading. If not, harness may be defective. Check for cut or pinched wires. Make sure that the local access is connected. Turn console power switch to ON, place the console in “MAN” mode and turn the boom one switch ON. Using a volt meter, check from a good frame ground to each servo wire (red and black on 3-pin, violet and gray on 10-pin). There should be about six volts on each wire. Holding the “+/-” switch up (“+”) should cause one wire (black or gray) to pulse from six toward four volts and the other wire (red or violet) to pulse from six toward eight volts. Holding the “+/-” switch down (“-”) should cause the opposite results. Servo Valve Flow Input: Turn the rotary dial to the flow rate position and disconnect the flow sensor (green tie) from the main harness. Check for 12 volts between pins B (white) and C (black) of the main harness flow cable (green tie). Using a clip lead or other jumper wire (such as a paper clip bent in a “U”), rapidly short together pins A (red) and C (black) of the 3-pin connector several times (See Illustration 21). The console should respond with some flow rate reading. If not, harness may be defective. Check for cut or pinched wires. Make sure that the local access is connected. The best way to test the servo valve is with a known working console. Flip the power switch to ON, place the console in “MAN” and turn all the boom switches ON. With the servo valve connected to the servo valve lead on the main harness, holding the “+/-” switch up (“+”) should open the servo valve. Holding the “+/-” switch down (“-”) should close the servo valve (provided the console has passed the Servo Valve Control Signal Test). The servo valve should operate smoothly from fully open to fully closed, in both directions. If a known working servo valve will not run at all or takes more than 20 seconds to run from fully open to fully closed, check for low voltage or poor power connection. Illustration 21 C B You may also use a 9-volt transistor battery. Connecting the battery to each terminal on the servo valve should cause it 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 fully open to fully closed, in both directions. Do Not connect 12 volts directly to the servo valve. Damage may result. A Pressure Sensor PRESSURE SENSOR Input: The only way to field test 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 input is to connect it to a known working pressure sensor, apply pressure and verify the correct pressure reading on the console display. Flowmeter -------- Warning -------- Shaking the flowmeter end to end should produce 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 Flowmeter Assembly and Cleaning on page 41 for details. To prevent serious injury, do the following: 1.Always wear gloves, goggles and other necessary equipment when handling NH3 apparatus. 2.Do not cross thread. Use anti-seize lead base thread compound. Solenoid Valves 3.Thoroughly bleed hoses before disconnecting NH3 apparatus. If 12 volts are present between the two harness wires to solenoid, but valves will not activate, consult the solenoid valve manufacturer. 35 4.Completely evacuate NH3 apparatus before servicing. Troubleshooting (cont) Plumbing Panel Harness The MT-9000 Series NH3 plumbing panel harness is installed on the plumbing panel at the factory. It connects the flowmeter, servo, shut-off valve and remote access speed to the main harness. This harness also contains the hold/cut-out Hall-effect adapter, which disables flow pulses from reaching the console when the shut-off valve is off.

HARNESS CONNECTS TO NH3 PLUMBING PANEL. 36 SHUT-OFF VALVE Troubleshooting (cont) Flowmeter Cleaning and Assembly Important: Opening the flowmeter will void the Flow Calibration value assigned to your unit. However, you may need to take the flowmeter apart for periodic cleaning or to remove an obstruction. NOTE: The turbines have magnets built into the fins. There are no visible magnets on the inside of the cavity. 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). 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 Illustration 22B below for reassembly instructions. Assembling Flowmeter Place turbine in non-sensor housing. Position Teflon gasket on housing. (Teflon gasket may be reused, but will eventually need to be replaced). Carefully set other housing in place. Drop all screws into holes. Hold nuts in place and fingertighten screws. Making sure Teflon gasket is still properly aligned, evenly tighten all screws. Attach tag. 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. 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. 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. Illustration 22A shows you what a new shaft looks like. When both ends of the shaft are worn to the point of drag, the turbine must be replaced. Accuracy of flowmeter readings cannot be guaranteed for flow rates below the meters’ ‘minimum pounds per minute’ rating. Recalibration is required before field operation.

An adjustable, non-magnetic (stainless steel) band clamp may also be substituted. • Attach sensor bracket to vehicle transmission with bolts, lockwashers and nuts provided. See Illustration below. (Use self-tapping screws if bolts are not practi cal.) Use either the short or long end of the bracket as a base. (Allow enough room between the bracket and the magnets so that when properly spaced, the tip of the sensor will extend 1/4” [7mm] or more beyond the locking nut.) • Turn one locking nut onto threaded sensor and insert sensor into large hole selected on mounting bracket. Turn on remaining locking nut. Set sensor to proper distance from magnets (1/4” to 1/2”, or 6 to 13mm). When distance is set, tighten nuts to lock sensor in place. • Secure sensor cable to frame with cable ties. Place first tie as close to sensor assembly as possible. 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” (.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 possible. This will ensure proper 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 degrees apart). The polarity (north and south poles) detected by the Hall-effect speed sensor 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. • Attach magnets onto drive shaft, one NORTH pole side out and the other SOUTH (dashed) pole side out, by wrapping cable tie around shaft and magnets.
