Electrical Installation

This section explains how to hook-up your SprayMate a 12-volt power connection, and how to connect your boom shut-off valves.

The SprayMate

II must be connected to a 12-volt DC negative ground electrical system. Use your test light to locate a terminal or wire connected to your ignition switch which is “hot” when the ig ni tion is turned on and “dead” when the ignition is off.

POWER/BATTERY CONNECTION

Locate the power cable lead on the SprayMate and route to the battery. In routing cable to con sole, avoid ar eas where the ca ble may be sub ject ed to abra sion or excessive heat. At tach the BLUE wire (ground) to a screw or bolt on the equipment frame. See Il lus tra tion 2. Be sure there is a good metal-to-metal con tact. Connect the ORANGE wire to the positive battery terminal.

Connect the power to the SprayMate

II console by plugging the 2-pin M/P tower on the power cable into the 2-pin M/P shroud of the display console.

II to

II harness

ON/OFF SWITCH CONNECTION

The SprayMate either using a switched (ignition) source or the optional power switch to turn the system on.

If the switch is used, simply mount the switch bracket as shown on page 11, and plug the connector into the mating cable from the console. If you want to use the ignition switch to turn the system on and off, using the 72” 2-wire extension cable, plug the connector into the mating plug for the console and connect the black wire to the switched power source (terminal or wire). DO NOT connect the red wire.

Speed Sensor Installation

PLEASE NOTE: If you have purchased a Vansco speed sensor, disregard the following section on magnetic speed sensors and install the Vansco as described in the instructions included with the unit.

Locations where the sensor may be installed:

1. Non-driven wheel on tractor, vehicle or implement. This

is less susceptible to errors resulting from wheel slip.

2. Tractor, vehicle or planter drive shaft. This type of

mounting is recommended for trucks, four-wheel drive tractors or other equipment that has poor or no access to a non-driven wheel.

Magnets

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. On tractor or implement wheels the general rule of thumb is one magnet for each wheel bolt (minimum of two, and always an even number). For drive shafts or small wheels (ATV’s), two magnets are usually adequate.

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.

Example in English/Turf units: 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.

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 5A.

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 5B.

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 5C.

Speed Sensor Installation

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 SprayMate 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 6.

NOTE: Observe magnet polarities (see previous page).

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 connector on the main harness. 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

Installation (cont.)

Mounting and Plumbing Flowmeter

The f lowmeter must be installed in the main line after any strainers, return lines, or valves. Securely mount flowmeter in an area away from intense vibration. A vertical installation with flow entering the bottom is preferred, especially at rates below 5 gallons per minute. Other orientations are sufficient providing the flowmeter remains full of fluid. To avoid erratic flow readings allow a minimum of 6” of straight tubing at the flowmeter input and output. If installation constraints don’t allow this keep bends as gentle as possible. Micro-Trak® flow meters are bidirectional (exception: green plastic turbine and mag flowmeters are one direction only). Flipping the flowmeter periodically (black nylon and stainless steel Micro-Trak® manufactured models) to reverse the flow will greatly extend the life of the flowmeter by evening out bearing wear.

Installing Flow Sensor Cable

With the flowmeter in place, install the flow sensor cable.

The flow sensor cable has a GREEN sensor body and mates with the 3-pin connector on the main harness marked with a GREEN cable tie. Screw sensor all the way into hole of flow me ter. Tighten 3/8” jam nut to secure sen sor in place.

Manual Pressure Relief Valve

If you have a positive displacement pump or a cen trif ugal pump capable of generating excessive pressure, you must in stall a pressure relief valve and adjust it to a safe max i mum 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 9.

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 System Checkout, pages 32-33.

See Illustration 10.

Servo, Throttling Valves

For BYPASS installations, the servo valve installs in an unrestricted return line to the inlet of the pump or directly into the tank. The console must be calibrated for bypass operation, see Calibration section. 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 11. 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 on page 32-33 for proper valve adjustment procedure.

The servo valve connects directly to the 3-pin connector on the main harness. If more length is required, use a 3-pin W/P extension cable of the appropriate length.

IMPORTANT NOTE: If using the SprayMate old-style Micro-Trak® servo valve, the valve voltage must be set to 8 volts. See “Special” Calibration Valve Voltage section on page 27.

Remote Run/Hold

The run/hold sensor cable has a BLACK body and mates with the main har ness ca ble having a GRAY cable tie near the 3-pin M/P con nec tor. Make certain that you install the correct sen sor cable and connect it to the correct connector on the main harness. See Illustrations to the right.

IMPORTANT:

If not using Run/Hold cable for remote use, make certain a dust cover with jumper is installed.

• The basic idea is to 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 of the magnet. Install the magnet with the dashed line facing the sensor. When the mag net is away from the sen sor, the con sole will be in HOLD and the area and distance counting functions will be disabled. 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 black jumper wire in the dust cover and splice on an appropriate length of wire to reach your switch. Do not connect to a switch with power.

Care and Maintenance of your SprayMateTM II

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 flush 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 (689 kpa).

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

• Some chemicals may damage the turbine material. If you are in doubt, contact the chemical manufacturer.

Entering Calibration Values

To enter or change any of the system’s calibration values, you must enter calibration mode. To enter calibration mode, STOP the vehicle, turn all booms OFF or put the console in HOLD and press and hold the CAL button until the “CAL” icon appears (approximately one second). (NOTE: Calibration

may be entered while moving, but it is not rec om mend ed to attempt calibration while the vehicle is mov ing.) The console

will remain in calibration mode, with the RED warning light illuminated until you exit calibration or turn power OFF.

Once in calibration mode, you may change any one, all, or none of the values, in any order. position, simply turn the rotary selector to the desired po si tion. Calibration positions are identified by the WHITE labeling on each side of the rotary selector. All values are entered and adjusted using the “+” and “-” but tons on the front panel.

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 (tenth of a centimeter) with the fol low ing method:

METHOD: Mark the tire with a piece of chalk and mea sure the

distance traveled on the ground for one com plete rev o lu tion. See Illustration 16. For improved accuracy, it is recommended that you perform this function in field conditions, measure several revolutions, and take the average.

Divide the measured revolution by the number of magnets installed to get your starting SPEED CAL calibration value. Once calibration of the system is complete, this number should be fine-tuned for optimum accuracy.

NOTE: For fine-tuning the SPEED CAL value, see Appendix B on pages 43-44.

Illustration 16

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 cal i bration.

Any number between 10 and 15 (255 mm to 380 mm) is a good starting value.

NOTE: For fine-tuning the SPEED CAL value, see Appendix B on pages 43-44.

To determine SPEED CAL, measure the distance of

one complete wheel revolution and divide by the

number of magnets installed.

The SprayMate II or Automatic mode. In manual mode, the application rate (GPA or LPH) is set using the “+” and “-” buttons; the application rate will vary depending on the vehicle speed. The manual mode is useful for system set up, spot spraying, etc.

To turn on the AUTO mode, press AUTO/MAN button so the AUTO icon appears in upper right portion of display. In automatic mode, the system will control the flow rate to maintain the calibrated application rate (GPA/LPH) when the vehicle speed changes, or booms are turned on or off. To operate the system in automatic mode, simply start the pump, turn on the desired number of booms, place the RUN/HOLD switch (if used) in the RUN position and drive. NOTE: In AUTO mode, the system will

not turn the booms on until it has a speed signal. Use either the RUN/HOLD switch or remote RUN/HOLD sensor to turn the system off and on when turning around or to stop spraying at any time. See the following sections for operation details.

CONSOLE POWER/SYSTEM ON/OFF: The system can be

turned ON and OFF by either the ignition switch, if the provided wire is connected to a power source switched by the ignition, or by using the optional ON/OFF switch and bracket kit. When the console is turned on, it will display the number of hours of operation for 2 seconds, then it will display the software version along with the “v” icon for 2 seconds before it begins normal operation.

DISPLAY: During normal operation, the console will display information selected by the rotary switch position. Typically the rotary switch will be set on RATE, as shown in illustration to the right. With RATE selected, the console will display the Application Rate in units of gallons per acre (liters per hectare). See DATA DESCRIPTION on next page for additional

information about data displayed.

RUN/HOLD SWITCH: The RUN/HOLD is the master switch for turning all (active) booms on and off. This function can be done either manually with the included RUN/HOLD switch, or automatically, using the optional RUN/HOLD sensor kit.

AUTO/MAN BUTTON: 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 the AUTO icon when automatic control mode is active and the MAN icon when manual control mode is active. NOTE: IF IN

“AUTO” MODE AND NO SPEED SIGNAL IS PRESENT, SYSTEM WILL SHUT OFF THE BOOMS AUTOMATICALLY.

“+” AND “” BUTTONS: During normal operation, when automatic “AUTO” control mode is active and the rotary dial is set to RATE, each press of the “+” or “-” buttons will increase or decrease the target application rate by the amount of the calibrated adjust rate (Delta).

During normal operation, when manual “MAN” control mode is active and the Run/Hold switch is in the RUN position, pressing the “+” or “-” buttons will increase or decrease the application rate by opening or 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 VOLUME/MINUTE, pressing the “+” or “-” button will increase or decrease the flow rate without having the boom valves turned on, by opening and closing the servo valve (control valve). This can be useful for system pressure checking.

ONTHEGO “DELTA” RATE ADJUSTMENTS ADJUST RATE:

The calibrated target rate in gallons (liters) 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 “+” or “-” 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 switch must be set to the RATE position.

Example: Adjust Rate = 1.0 and Target Rate = 10.0

With AUTO selected and the rotary selector turned to 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.

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 or calibration changes occur, or if the unit is turned off.

Operation (cont.)

Console Switches & Buttons

BOOM SWITCHES: The system monitors the status of the boom switches to determine whether they are ON or OFF. The console accumulates area based on the calibrated boom widths. When an individual boom is turned OFF, the respective width is subtracted from the total width to accumulate area based on the new active application width. If the rotary switch is in the RATE or AREA/HOUR position, the numbers 1, 2, and 3 on the display will light when their respective boom is ON.

WARNING DEVICE: The console is equipped with a RED warning light. The light will automatically turn on and flash when the actual application is plus or minus 10 percent of the calibrated target rate, or if the TANK alarm feature is activated and the tank is below the set point (display will also flash “FILL” message). If the light stays on while in AUTO, refer to the troubleshooting section of this manual. The RED warning light will also be illuminated when calibration mode is active on the console.

ROTARY SWITCH: During normal operation, you can view any one of eight monitored functions by turning the rotary switch to the appropriate position. The functions that are active during normal operation are the TAN boxes. Calibration positions are identified by the WHITE labeling on each side of the rotary selector (Please refer to Calibration

section for details).

Rotary Switch Positions

RATE: Displays the actual number of gallons per acre (liters per hectare) being applied. When the SprayMateTM II is used in conjunction with a Micro-Trak® NH3 control kit, and NH3 has been selected in “Special” Calibration, the console display will read pounds (kg) of actual “N” per acre (hectare) being applied.

TANK: Displays amount remaining in the tank. When the tank is refilled, and the tank volume has been entered in “Special” Cal, the TANK amount can be reset to a full tank by simply pressing the “+” button for 1 second while the rotary switch is in the TANK position. The amount in the tank can be decreased by using the “-” button.

VOLUME/MINUTE: Displays the actual gallons (liters) per minute being applied. When the SprayMate conjunction with a Micro-Trak® NH3 control kit, the console display will read total pounds (kg) of NH3 per minute being applied.

VOLUME: Displays the total gallons (liters) applied since the active counter was last reset to zero. When the SprayMate II is used in conjunction with a Micro-Trak® NH3 control kit, the console display will read total pounds (kg) of NH3 applied since the counter was last reset. To select a pair of AREA and VOLUME counters, use the “+” button to select set 1, 2 or 3, indicated by the small numbers in the lower right on the display. Do NOT use the “-” button to select counters because the button will clear them. (See Resetting System Counters on page 30.) This active pair of counters may be reset to zero independent of other system counters.

Operation (cont.)

Resetting System Counters

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

1. Turn the booms OFF or put the system in HOLD.

2. Turn the rotary switch to the counter to be reset.

3. To reset distance turn the rotary switch to DISTANCE and simply press and hold the RESET button until the display reads zero. The display will show the word “CLEAr” during this process, and will show 0.0 when reset to zero is complete.

4. To reset the volume and area counters; there are three independent AREA counters, paired with three VOLUME counters. The active pair of counters is indicated by the small numbers in the lower right area of the display (1,2, or 3) when the rotary switch is in the AREA or VOLUME position. Select the pair of counters you want to use by pressing the “+” button. The small number will increment each time the “+” button is pressed (from 1 to 3, then rolls back to 1). DO NOT attempt to select the counter number by using the “-” button, because that will clear the active pair of counters if held for 2 seconds. If the “-” button is accidentally pressed, the console will display “CLEAr” to alert the user that the counters will be cleared. If the user continues to hold the “-” button for 2 seconds “CLEAr” will disappear and be replaced by 0.0, indicating that the selected pair of counters has been cleared.

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 SprayMateTM II 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, you set up your system to allow the SprayMate tank with clean water. DO NOT use chemicals until the entire sys tem is completely checked out and operating properly.

IMPORTANT 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.)

NOTE: 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.

Troubleshooting (cont.)

General

All SprayMateTM II 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 or reversed terminals. (Console requires 12 volts for proper operation). Check connections of ignition or power switch.

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 sensors and console inputs on page 36.

DISTANCE COUNT IS INACCURATE

Wheel circumference was incorrectly measured or entered. Review calibration, re-adjust and test.

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. (Make sure no width is entered for unused booms.) Verify accuracy with formula:

Acres = Distance x Width in feet/43560

Hectares = Distance x Width in meters/10,000

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.

BOOMS SHUTOFF

If you are in AUTO with no speed, the booms will shut-off.

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 in Appendix C.

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.

CONSOLE IS ERRATIC IN OPERATION

If you have a two-way radio, it may be mounted too close to the console. Keep all SprayMate radio, its antenna and power cable.

Ignition wires may be causing the console to malfunction. Keep SprayMate install ignition suppressor.

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

Check the VALVE SPEED calibration number in “Special” Calibration. If the RATE tends to overshoot or oscillate, the VALVE SPEED setting may be too high for the control valve being used; reduce the VALVE SPEED setting by 1 (range is

-4 to +3).

II cables away from ignition wires, or

II cables away from the

DISPLAYED MEASUREMENTS DO NOT MAKE SENSE

The console may be in the incorrect measurement mode (English or metric). See page 22 for instructions.

DISPLAY READS “99999”

DISTANCE, AREA, and VOLUME counters read “99999” when they have reached their maximum count. Reset to zero to resume counting.

SYSTEM OPERATION CONTROL IS SLUGGISH IN AUTOMATIC MODE

Check the VALVE SPEED setting in Special Calibration. If using a slow valve (4 seconds or more, close to open) increase the VALVE SPEED setting.

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.

Troubleshooting (cont.)

Checking Individual Components

CONSOLE

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 10.

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.

POWER

Check power source with the MT-101 or a 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

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. This particular type of Hall-effect sensor “closes” when near the south pole of a magnet and is otherwise “open”.

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.

MAGNETIC HALL-EFFECT SPEED AND FLOW SENSORS

Caution: Improper connection or voltage could damage the Hall-effect sensor. 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 u lar 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 mag net will “open” the Hall effect and the south pole of a magnet will “close” the Hall effect.

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 (around 300 ohms).

VANSCO RADAR SPEED SENSOR

1. Carefully check your installation and operating instructions. The following are tips for troubleshooting;

2. Disconnect the radar adapter cable from the console harness

3. Check for 12 VDC between pins B and C of the main harness connector (yellow tie). If not present, console or harness may be defective.

4. Using a jumper wire (paper clip bent into a “U”), rapidly short together positions A and C of the main harness speed connector (yellow tie) several times. The console should respond with some speed reading. If not, the console or harness may be defective.

5. Reconnect the radar adapter cable to the main harness speed connection (yellow tie).

6. Disconnect the radar from the radar adapter cable.

7. Check for 12 VDC between pins 1 and 3 of the radar adapter connector. If it is not present but was present in step 2, the radar adapter cable may be defective.

Holding the tip of the sensor up to the south pole of a magnet should result in a very low resistance (around 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. There should be continuity — near zero ohms.

8. Using a jumper wire (paper clip bent into a “U”), rapidly short together positions 2 and 3 of the radar connector (round 4-pin) several times. The console should respond with some speed reading. If not but had a reading in step 3, the radar adapter cable may be defective.

9. If system passes all above tests, the radar may be defective.

Troubleshooting (cont.)

Checking Console Inputs

CONSOLE INPUTS

If there is no response from any of the following tests, refer to the main wiring diagram 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 switch 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 17). The console should respond with some speed read ing.

FLOW INPUT

Turn rotary switch to VOLUME/MINUTE 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 (pa per clip bent in a “U”), several times rapidly short together pins A (red) and C (black) of the 3-pin connector. The con sole should re spond with some flow rate reading.

Illustration 17

SERVO VALVE CONTROL SIGNAL

With the console turned ON, put the console in MANUAL mode, place the remote Run/Hold switch in the RUN position and turn at least one boom switch to ON. Using a voltmeter or simple test light, check from a good frame ground to each of the servo wires on the main harness connector. You should get 0 volts on each wire. Holding the “+” button should cause the RED wire to pulse toward 12 volts (light will pulse). Holding the “-” button should cause the BLACK wire to pulse toward 12 volts (light will pulse).

SERVO VALVE

The best way to test the servo valve is with a known working console. Turn console ON, put the console in MANUAL mode, place the remote Run/Hold in the RUN position, turn the rotary switch to RATE and turn at least one boom switch 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. NOTE: Assuming you are in bypass configuration

(provided the console has passed the Servo Valve Control Signal test). The servo valve should operate smoothly in both directions, from fully open to fully closed.

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 in both directions, from fully open to fully closed.

CB A

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 (green) and C (violet) of the main harness remote run/hold cable (grey tie). Placing a clip lead or other jumper wire (such as a paper clip bent in a “U”) between pins A (blue) and C (violet) of the main harness run/hold connector (grey tie) should turn off the “HOLD” icon on the console display. Removing the jumper should turn on the “HOLD” icon 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 Flow me ter Assembly and clean ing

on page 46 for details.

PLUMBING

Proper plumbing is a very important factor in obtaining optimal performance from your SprayMate II II system. The chart on the next page 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 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 38 - 39.

General

In order for your sprayer to function properly, it must be correctly plumbed. The system diagrams (On pages 16 and 17) plumbing configuration that works best with the SprayMateTM II Sprayer Controller. 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 flowmeter (boom) line, the servo 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.

show the

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.

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.)

General

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. 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.

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.

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.

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 pages 32 and 33. If the throttle valve needs

to be more than two thirds closed, open the Range valve slightly and perform the Pre-Field System Checkout again.

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 32-33.

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

fluctuate greatly in AUTO.

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.

PRESSURE RELIEF VALVE

The pressure relief valve is used to avoid excessive pressure when the booms are turned off. Start with the handle screwed mostly out. Slowly bring pump up to operating RPM (make sure pressure does not go too high). Put the SprayMate II II in MAN and turn boom on. Hold adjust switch to “+” for about 30 seconds to fully close servo valve. Turn booms OFF. Now slowly screw handle in until maximum desired pressure is reached. Lock handle in place with locking nut or collar.

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

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 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.

Sensor Body

(Green)

• 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. See Illustration below. Use either the short or long end of the brack et as a base.

• 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 (¼” to ½”, 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.

Fine Tuning Speed/Distance Calibration Val ue (With Run/Hold Switch Kit Installed)

This procedure is used to verify the calibration of systems WITH the Run/Hold Switch Kit or an optional remote run/ hold kit installed. In order to achieve accurate measurements, each step in this fine tuning procedure should be performed as precisely as possible.

Note: If your system does not have a run/hold switch kit or remote Run/Hold sensor installed, refer to next page for instructions.

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 sur face,

such as a hard-surface road, will re sult in dif fer ent read ings than exact field con di tions.

• Measure a distance of 1000 feet (500 meters). Clear ly mark the beginning and end points with flags or some thing highly visible to the operator.

PROCEDURE

1. With the console turned ON, place the Run/Hold switch

in the HOLD position. The HOLD icon will be displayed. 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 returns to 0 (approximately one second). The word CLEAr will be displayed when reset is pressed.

4. With the rotary dial still at DISTANCE (SPEED CAL), press and hold the “CAL” key for one second. Once the console is in “CAL,” CAL and the speed calibration value will be displayed. Momentarily press CAL and the word CAL will begin to flash and the distance travelled will be displayed. See illustration below.

5. When the display shows distance (“CAL” is flashing), veri fy wheth er the number displayed is the ex act dis tance you drove (with in +/- 1 - 2 %). If not, press the “+” or “-” key 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.

6. When the number shown on the display match es (as close ly as possible) the ac tu al dis tance driv en, you have ar rived 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. You may check the calibration number by momentarily pressing CAL. The word CAL and the SPEED CAL number will appear. Exit “CAL” by pressing “CAL” for one second.

The speed sen sor is now calibrated. To verify proper calibration, repeat the procedure a sec ond time. Write down the new speed calibration 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.

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 (door handle, mirror, step, etc.). You should begin driving the course well ahead of the starting flag and drive past the ending flag, using the Run/Hold 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.

3. Place the Run/Hold switch in RUN 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 pre-measured course and place the Run/Hold switch in HOLD, when the marker on the vehicle passes the ending flag, to stop the distance counting function. The console display should read “HOLD”. See Illustration to the right. Stop the vehicle in a level and safe area and continue with this procedure.

Fine Tuning Speed/Distance Calibration Val ue (Without Run/Hold Switch Kit Installed)

This procedure is used to verify the calibration of systems WITHOUT run/hold switch kit installed. In order to achieve accurate measurements, each step in this fine tuning procedure should be performed as precisely as possible.

Note: If your system does have an optional run/hold switch kit installed, refer to page 43 for instructions.

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 sur face,

such as a hard-surface road, will re sult in dif fer ent read ings than exact field con di tions.

• Measure a distance of 1000 feet (500 meters).

Clear ly mark the beginning and end points with flags or some thing highly visible to the operator.

PROCEDURE

1. You are now ready to drive the measured course. Pick a location on the vehicle to use as a marker for starting and stopping (door handle, mirror, step, etc.). Position the vehicle at the beginning of the measured course with the marker adjacent to the starting flag and STOP the vehicle. Turn all booms OFF.

2. With the console turned ON, 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 returns to 0 (approximately one second). Booms must be OFF. The word CLEAr will be displayed when reset is pressed.

4. With the rotary dial still at DISTANCE (SPEED CAL), press and hold the “CAL” key for one second. When the CAL icon appears, the num ber dis played is the speed calibration value. Press and release the CAL button. The CAL icon will begin flashing and the display will show distance travelled.

5. When the display shows distance (“CAL” is flashing), veri fy wheth er the number displayed is the ex act dis tance you drove (with in + or - 1 - 2 %). If not, while the display shows distance, press the “+” or “-” key 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 displayed value. If the display reads too low, use the “+” key to raise the displayed value.

6. When the number shown on the display match es (as close ly as possible) the ac tu al dis tance driv en, you have ar rived 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. Exit “CAL” by pressing “CAL” for one second.

3. Begin driving the pre-measured course. The console display numbers will increase, adding to the distance total as you drive. STOP the vehicle when the marker is adjacent to the ending flag. The vehicle MUST not move until the remaining steps of this procedure have been completed.

Fine Tuning Flowmeter Calibration Value

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 val ue. Enter that value as a starting point and use this pro ce dure to fine-tune that value for your specific in stal la tion and spray ing application. This procedure should be re peat ed each time a new solution is being applied (Differ ing so lu tions will have a different spe cif ic gravities and different flow char ac ter is tics) or when the flowmeter in stal la tion has been altered.

PROCEDURE

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

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

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

3. Turn console rotary selector to the VOLUME po si tion. Select the counter (1-3) that you want to use. Press and hold the RESET button until the dis play reads 0

(About 2 seconds).

4. Turn on all booms, and run a known amount of water (Preferably 100 gallons or more).

5. Turn off all booms. Compare the console’s VOLUME reading with the known amount of water run. See Illustration. If the two amounts are within one or two per cent, no fine tuning is required. If the two amounts are more than two or three percent dif fer ent, con tin ue with the next step.

the CAL icon.

7. Momentarily press the CAL button. The CAL icon will begin to flash and the total volume will be displayed.

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

9. Momentarily press the CAL button. The word CAL and the flowmeter calibration number will be displayed. You will notice that the flowmeter calibration value has changed. Write down the new flowmeter calibration value. This is your “fine tuned” calibration value, keep it for future reference.

10. Exit calibration by holding the “CAL” button until the red warning light goes out (about one second).

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.

6. With the console still in the VOLUME position, enter calibration (Boom switches OFF, hold the CAL button until red warning light comes on; about one second). The dis play will show the flowmeter calibration value and

Flowmeter Assembly

IMPORTANT: 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 below for reassembly

instructions.

OPENING THE 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. Illustration 18 shows you what a new shaft looks like. When the shaft is worn to the point of drag, the turbine must be replaced.

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 THE FLOWMETER

Stainless steel meters use a Teflon gasket. Sealants are normally not required. Plastic meters use an o-ring (Quad-ring). Apply a small amount of silicon grease for lubrication. Gaskets and o-rings may be reused several times but eventually may need replacement.

Place the turbine in the non-sensor housing. Position gasket/o-ring; carefully place sensor housing over turbine. Drop all screws into holes. Hold nuts (and lock washers on stainless meters) in place and finger-tighten screws. Ensure proper placement of gasket / o-ring and 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. Recalibration is required before field operation.

Speed Sensor Installation

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 spevved 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 connect to the main harness lead with the GREEN tie. See system illustration below.

INSTALLATION NOTE: The main harness provides two connection points for the speed sensor. For speed sen sor instal la tions in the cab or near the control con sole, it may be more practical to use the local access con nec tor on the console end of the main harness (longer of the two cables with YELLOW tie). Us ing this connection point will disable the connection point on the implement end of the main harness. For speed sensor in stal lations on implements, it may be more practical to use the speed connector on the implement end of the main harness. When using this connection point, make certain that the local access connector for speed/distance is mated together. (Connectors with YELLOW ties on console end of main harness mated together.)

NH3 Kit Plumbing Installation - Liquifier™, Liquifier Max™ & Liquifier Junior™ (NH3500)

INSTALLATION:

Remove any existing metering valves. If the old metering valve has a built-in manifold, it is recommended to install a separate new manifold for the Liquifier™ kit. Another option, although not recommended, is to use the existing manifold, making certain the old metering valve is in the maximum open position to allow for minimal restriction of flow through the plumbing. There should not be any positive shut-off valves installed in the plumbing between the Liquifier™ kit shut-off valve and the knives.

Install the plumbing panel on the tool bar frame using the carriage bolts and flange lock nuts through the top and bottom brackets of the system. Trim any excess length off the bolts if required. Attach the hose from the breakaway coupler to the strainer inlet. Check for proper hose length for operation of the disconnect mechanism of the breakaway coupler. Connect the manifold hose to the servo valve outlet. Check for proper hose length to avoid kinking at the hinge points.

INSTALLATION NOTE: It is recommended to use an NH3 compatible thread sealing compound such on all pipe thread fittings

IMPORTANT!

Vapor tube plumbing MUST be connected to the Liquifier™ vapor outlets for the system to work correctly. Operating the Liquifier™ without the vapor tubes will present serious health and safety hazards.

Locate the ½” EVA vapor hose supplied with the kit. Starting on one half of the tool bar, connect the ½” hose to the outside steel vapor tube. Route the hose up the shank and along the tool bar frame to the inside steel vapor tube. Allow enough extra hose to avoid kinking at hinge points. Cut the hose to length and attach to the inside steel vapor tube. Install a ½” x ¾” x ½” tee fitting approximately halfway along this hose between the outside and inside steel vapor tubes. See Illustration below. Repeat the same procedure for the steel vapor tubes on the other half of the tool bar. Secure all hoses with properly sized hose clamps. Secure the hoses to the tool bar frame with cable ties.

Locate the ¾” EVA hose supplied with the kit. Connect to one of the ½” x ¾” x ½” tee fittings and route along the tool bar frame to the vapor outlet connections on the Liquifier™. Repeat for other half of tool bar. Allow enough extra hose to avoid kinking at hinge points. Secure all hoses with properly sized hose clamps. Secure the hoses to the tool bar frame with cable ties.

FOR ALL NH3 KITS

Weld the steel vapor tubes to the back of your liquid tubes. All electronic equipment, including the console and radar speed sensor, MUST BE

DISCONNECTED BEFORE WELDING ON EQUIPMENT. The

four steel vapor tubes should be evenly spaced across the applicator (two per side) and installed so that only their wear resistant surface contacts the soil. Mount the tubes just high enough to avoid plugging.

number to the working width of your tool bar in inches (thousandths of meters).

To enter standard calibration mode, turn the shutoff valve off and press the CAL button for 1 second. Some of the calibration factors are the same as a liquid system, but there are some important differences:

Your Micro-Trak® NH3 flowmeter has been tested at the factory and assigned a “FLOW CAL” value (pulses/lb N) to make it operate properly with the SprayMate II II console. This number is stamped on the metal tag attached to the flowmeter. See Illustration below. This is a starting point only. The value must be fine tuned. See Fine-Tuning Flowmeter Calibration for NH3 on page 59. When entering the flow cal value, take note of decimal point placement.

MINIMUM FLOW:

Enter a minimum flow rate of 10.0 lbs. per minute (5.0 kg per minute) of NH3. This will prevent the system from applying below the recommended

SETTING TOOL BAR WIDTH:

In order to accurately measure the pounds (kg) of “N” 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 (millimeter).

Your “working” width will be the number of knives times the knife spacing in inches (meters). For example, if you have 8 knives spaced at 30 inches, the working width is 240 inches.

See Illustration below.

PROCEDURE:

1. Start with a full nurse tank. Make certain that you have an accurate scaled weight of the full tank. You will want to apply a minimum of 1,000 pounds of NH3 for this procedure. The larger the volume of NH3 used, the more accurate the calibration will be.

2. With Boom 1 switch turned OFF, turn the rotary selector to the VOLUME (1) (2) (3) position. Select which pair of VOLUME/AREA counters (1, 2, or 3) that you want to use by using the “+” button ONLY to select the pair of counters as identified by the small number in the lower right area of the left-hand display. If you attempt to use the “-” button, it will clear the selected counter pair (CLEAr will be displayed before the counters are cleared). After you have selected the counter pair number, press and hold the RESET button until the display reads 0.0.

3. Proceed to the field and perform actual application (turn Boom 1 switch to ON) until at least 1,000 pounds of NH3 has been applied. (One nurse tank is preferred). The larger the volume of NH3 applied, the more accurate the calibration will be. Obtain an accurate scaled weight of the partially used nurse tank. The difference between the starting and ending weight is your calibration weight.

7. When the TOTAL FLOW value is displayed, use the “+” or “-” button to adjust the value to match the amount of NH3 run.

8. Momentarily press the CAL button. The CAL icon and the flowmeter calibration number will be displayed. You will notice that the flowmeter calibration value has changed. Write down the new flowmeter calibration value. This is your “fine tuned” calibration value, keep it for future reference.

9. Exit calibration by holding the “CAL” button until the red warning light goes out (about one second).

SprayMateTM II NH3 Specific

Field Operation - Troubleshooting for NH3

Always follow accepted safety precautions. Make sure that equipment is in good operating order. Before connecting the nurse tank to the applicator, check the electric shut-off valve of the SprayMateTM II system for proper operation.

After changing nurse tanks or after other periods of long shut-down, 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.

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 the flowmeter, and readings will be inaccurate. Typical manifold pressure ranges from 15 to 60 PSI (1 to 4 bar) depending on application rates and ambient temperature. If manifold pressure stops climbing but FLOW RATE continues to climb, vapor bubbles are present.

ADDITIONAL TROUBLESHOOTING TIPS FOR NH3:

See Troubleshooting section, starting on page 34.

In hilly or rough conditions the nurse tank dip tube will not remain submerged, allowing extra vapor in the system. This vapor is to 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.

In NH3 control systems, location of the frost build-up is an indication of system performance. The NH3 kit 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.

The strainer is a common source of excessive pressure drop and should be cleaned regularly. AFTER COMPLETELY DRAINING THE SYSTEM, remove the large plug and carefully clean the strainer’s screen. Also, periodically check the vapor tubes for obstructions.

Flowmeter Assembly (FM-750 N)

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. See illustration below for flowmeter

reassembly instructions.

TO OPEN THE FLOWMETER

Disconnect the hose from servo valve to manifold. Loosen the union hex closest to the heat exchanger. Remove the two “U” bolts that hold the servo/flowmeter assembly to the brackets. Unscrew the union from the heat exchanger and remove the servo/flowmeter assembly.

Use running water to rinse the assembly of any accumulated dirt. Remove the three flowmeter bolts, carefully open the flowmeter and remove the turbine. Thoroughly clean turbine and housings of any foreign material (dirt, pieces of teflon

tape, rust on magnets, etc.).

Set and spin the turbine in each flowmeter housing half. It should spin freely. If not, remove the turbine, wipe the shaft and try again.

WARNING

TO PREVENT SERIOUS INJURY, DO THE FOLLOWING:

TO ASSEMBLE THE FLOWMETER

Place the servo, flowmeter end up, in a vice or other suitable fixture. Set turbine in non-sensor housing. Properly position gasket on housing. (Gasket may be reused a few times but will eventually need to be replaced.) Pipe thread compound is not absolutely necessary but will insure a good seal. Be careful not to get compound inside flowmeter or turbine will stall. Carefully put other flowmeter housing (sensor half) in place. (Position the housing so that the two square lugs are lined up with each other.) Drop all three bolts into holes. Hold lock washers in place and finger tighten all three nuts. Nuts should be torqued to 120 in./lb. (13.56 nw/m). Attach tag by running wire between a bolt and the housings, and twisting.

Start with original calibration number and follow procedure in manual for verifying flowmeter accuracy.

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.

3. THOROUGHLY BLEED hoses before disconnecting NH3 apparatus.

4. COMPLETELY EVACUATE NH3 apparatus before servicing.
