INTRODUCING TASC FOR THE NEW GENERATION APPLICATORS

The TASC 6500 is a five channel controller. Two channels are designed to operate positional control valves, such as hydraulic or liquid flow control valves, while the other three channels are designed to operate either positional control valves or DC motors. This gives the MID-TECH TASC 6500 the flexibility to control almost any mobile applicator using a single console.

All five channels control spread or spray rates in relation to ground speed and width. Each channel has two programmable rates or can be changed by a percentage amount "ON THE GO". The TASC 6500 is easy to calibrate and operate and incorporates many self check features to help the operator keep the system running at peak performance.

The TASC 6200 is a simpler version of the TASC 6500 console. The TASC 6200 has two channels designed to operate positional control valves only.

1.1 POWER SWITCH

The power switch controls power to the console. The console has an "Auto Power Down" feature which powers the console off after an operator selectable time (default is 30 min) has elapsed. The console has a nonvolatile memory so it "remembers" the constants and data previously entered, even if the power is removed.

NOTE: The “Auto Power Down Feature is only available on the CE version of the console (CE designation label on back of console).

1.2 MODE SELECTOR " OPERATE/SET-UP " SWITCH

The mode selector switch selects between the operate mode and the set-up mode. This switch must be in the operate position for the system to control the chemical application process. The set-up position is used for entering information into the console. Anytime an incorrect switch setting is selected, an "Err" message will appear on the display.

1.3 THE INC/DEC SWITCH

The INC/DEC switch is used to change values appearing on the display. This switch is also used to zero accumulated data and to select special programming modes for the console.

1.4 THE DISPLAY SELECTOR SWITCH

The display selector switch is used to select information displayed and console functions to be adjusted. Each position will display different information depending on the mode selector switch setting. The following pages will explain the information displayed and functions available for each display selector switch setting. Anytime an incorrect switch setting is selected, an "Err" message will appear.

1.5 BOOM SECTION "ON/OFF" INDICATORS

The boom section on/off indicators show which boom sections have been selected. There is a maximum of nine boom sections available. When a boom section is selected, its indicator light will light.

1.6 FLOW CONTROL CHANNELS, PRODUCT SWITCHES

Two channels on the TASC are designated as flow control channels only. Both are designed to operate positional control valves. Channel C is normally used to control the spreader conveyor using a positional hydraulic control valve. Channel L is normally used to control a liquid application using either a positional flow control valve or a positional hydraulic control valve. This could be either a wet boom applicator or a liquid impregnation applicator.

Both channels can be preset for a standard rate and an alternate rate. When the switch is turned "ON", its indicator lamp lights to show the applicator has been selected at its standard rate. When "Alt.-Rate" is selected, the indicator lamp flashes to indicate a non-standard application rate.

1.7 CHEMICAL APPLICATOR CHANNELS, PRODUCT SWITCHES (TASC 6500 only)

Channels 1, 2, or 3, operating in Peristaltic or Non-Peristaltic modes, require that Channel L or C be ON in order for them to operate.

Channels 1,2 and 3, are used to control up to three separate chemical applicators. When operating in peristaltic or non-peristaltic mode, these three channels control the speed of a motor by varying the drive signal to that motor. Typical installations include the control of liquid injection pumps on a wet boom or granular co-applicators with a dry conveyor.

When channels 1, 2, or 3 are running in Flow Mode they operate like the L and C channels and can be used to control a positional control valve.

All three channels can be set for a standard or alternate application rate. When the switch is turned "ON", its indicator lamp lights to show the applicator is selected at its standard rate. When "Alt.-Rate" is selected, the indicator lamp flashes to indicate a non-standard application.

1.8 BOOM CONTROL SWITCHES

Externally mounted boom control switches are necessary for the proper operation of a TASC system. MIDWEST TECHNOLOGIES can provide several optional configurations for these switches to meet differing needs. The console must receive 12 VDC on the boom status line whenever a boom is turned ON.

A boom master switch is a recommended feature. It can be used to turn on or off all selected booms simultaneously.

1.9 GROUND SPEED OVERRIDE SWITCH

An optional ground speed override (GSO) switch can be used to temporarily operate the system using a pre-selected minimum speed. GSO brings the applicator on line quickly when starting from a dead stop and can also be used to maintain a minimum application rate when maneuvering the vehicle at very low ground speeds (Actual application rate, based on actual ground speed, is displayed). Finally, GSO can be used to empty the applicator from the cab while the vehicle is stopped (zero ground speed) (Display reads "- FLO").

TASC operates normally, when traveling above GSO speed or when the GSO switch is OFF. When the GSO switch is closed (ON), and the actual ground speed is less then the minimum speed preset in the console, the console automatically selects the GSO speed value to control application rates. As soon as the switch is turned OFF, or the actual ground speed increases above the GSO speed, TASC controls application rates based on the actual ground speed.

Mid-Tech 405-0075 Single Conveyor Switchbox

with Master Switch and Off/Auto/GSO Switch

If your GSO Switch is labeled "OFF / AUTO / GSO", then you must have the switch in AUTO (console controls to ground speed only) or GSO position (console controls to GSO speed if ground speed is below GSO speed). The OFF position operates the same as turning the STATUS switch off. (See paragraph 1.10 below)

CAUTION: When traveling at a speed slower than the GSO speed setting, this feature causes the product to be applied at a rate consistent with the GSO speed, rather than the true ground speed. Caution must be exercised when operating in this mode as serious over application can occur, if not used properly. When GSO is being used, and the true ground speed is less than the pre-selected “GSO” speed, the console sounds an alarm and the display flashes a “Too Slow” message to warn the operator of possible over application.

1.10 STATUS SWITCH

An externally mounted status switch can be used to turn TASC on and off. As long as this switch is ON (closed) TASC operates normally. Whenever the switch is OFF (open), TASC turns off the applicator channels.

The intent of the status switch is to control TASC through the normal operation of the vehicle. The status switch may sense the ON/OFF condition of the main applicator or it may sense an implement UP/DOWN condition. Use of the status switch can ease the operator work load.

2.0 CALIBRATION AND SET UP

NOTE: PLEASE READ THROUGH THE FOLLOWING SECTIONS COMPLETELY BEFORE YOU BEGIN CALIBRATION!

In order to control accurately, the TASC console requires certain information about your system, such as application rates, boom widths, test speed, etc.. Next, the rate sensor and ground speed sensor must be calibrated.

2.1 U.S. OR METRIC UNITS

The control console is capable of displaying two different units of measure, US and Metric.

* Items in parenthesis are the abbreviations that appear on the screen. ** No units displayed *** No units displayed after roll over of feet to miles or meters to kilometers

2.1.3 CHANGING UNITS

To change units, set the Mode Switch to “OPERATE” and the Display Selector to “SPEED”. The current speed units are displayed (MPH or KPH). Holding the INC/DEC switch down for about 10 sec. causes the display to alternate between U.S. and Metric modes. Release the DEC Switch when the desired mode is displayed.

2.2 SETTING CHANNEL 1, 2, 3 DRIVE METHOD (TASC 6500 ONLY)

The TASC 6500 Chemical Applicator channels (1, 2, 3) can use three different drive methods, depending on the type of equipment being controlled by the individual channel. "Peristaltic Drive" is used for peristaltic injection pumps. "Non-Peristaltic Drive" can be used for a granular bin motor. "Flow Mode" is used to control a positional control valve, such as a hydraulic flow control valve. You must use the appropriate drive method for proper operation.

A. Use the following switch settings to select the desired drive method (You should have to do this only once

unless you change your equipment configuration.).

B. Turn the rate selector switches, for any channels (1,2 or 3) that you want to set to non-peristaltic to "ON". C. Turn the rate selector switches, for any channels (1,2 or 3) that you want to set to FLOW MODE, to

"ALTERNATE RATE".

Any channels left "OFF" will be set to the peristaltic mode.

D. Hold the INC/DEC switch down while turning on the TASC power. After completing the start up routine,

the display settles on a series of o's, -'s, and F's. The o's correspond to the channels that are set to nonperistaltic drive, -'s indicate peristaltic channels, and F's indicate channels that are in Flow Mode.

F o -

Indicates channel 1 is set to "Flow Mode", 2 is set to non-peristaltic drive and channel 3 is set for peristaltic.

E. If it is ever necessary to reset the channel configuration, simply repeat the above procedure selecting the

desired switch configuration.

F. Whenever the TASC power is turned ON, the console momentarily displays the drive status of the three

chemical applicator channels (unless all three channels are in peristaltic mode).

2.3 SETTING THE SPLIT DRIVE OPTION

Each TASC control channel (1, 2, 3, L, C) has the option of operating in either standard or split drive. Split drive is used to control a channel where changes in boom settings do not affect the drive speed of the controlled shaft or motor. An example is a split conveyor with two separate drive motors feeding a two boom granular air delivery applicator.

If you can't decide whether to use split or standard drive on a particular control channel, contact your MID-TECH supplier, or the factory, for help.

A. Use the following switch settings to change from standard to split drive (you should have to do this only

once). Power OFF

Mode selector SET-UP Display selector L & CHEMICALS, APPL. RATE Booms and pumps OFF Hold the INC switch UP while turning the power on

The display will show an Err message when power up is completed.

B. Turn the desired product switch ON and the display shows which drive configuration is set (Stnrd for

standard or SPLit for split).

C. Select the desired configuration by holding the INC switch UP. The display alternates between standard and

split. The selection being displayed as you release the INC switch is locked in. (If the channel is in peristaltic mode the only choice is Stnrd.)

CE & S

D. Repeat steps B and C for each channel independently.

E. Turn the display selector switch or move the Mode switch to OPERATE to exit this function.

NOTE: Whenever a channel is set to the split drive option, all booms, to be used, must be turned "ON" and have widths entered before the calibration number can be changed. If a boom position will not be used it must be set to 0.

2.4 SETTING APPLICATION RATES

Each TASC channel can maintain a constant, preset application rate. To do this, the operator must enter the desired application rates.

2.4.1 SETTING C CHANNEL APPLICATION RATE

A. Set the console switches to the following positions:

Power ON Mode Selector SET-UP Channel C Product Switch ON (CENTER) Display Selector CARRIER, APPL. RATE

The display shows the current channel C application rate. B. Use the INC/DEC switch to set the value displayed to the new desired rate. C. Repeat with the Channel C Rate set to ALT-RATE. This establishes an alternate rate.

2.4.2 SETTING C CHANNEL PRODUCT DENSITY

TASC needs to know the product density in order to control the application rate of the product accurately. Product density is entered in pounds per foot3 (kilograms/tenths of meters3).

A. Set the console switches to the following positions:

Power ON Mode Selector SET-UP Channel C Product Switch ON Display Selector CARRIER, VOL. APPLIED

The display shows the current channel C product density.

B. Use the INC/DEC switch to set the value displayed to the new desired rate. C. NOTE: If channel C is being used as a liquid control channel, set the Product Density to 1.0

2.4.3 SETTING ALL OTHER APPLICATION RATES

A. Set the console switches to the following positions:

Power ON Mode Selector SET-UP Display Selector L & CHEMICALS, APPL. RATE Channel 1,2,3 or L Product Switch ON (CENTER)

The display shows the current standard application rates for each channel.

2-3

CE & STANDARD VERSION

TASC 6200/6500

Rev- 1

B. Use the INC/DEC switch to set the desired rate. Example, 64.0 for 64 Fluid Oz. (2 qts.) per acre.

NOTE: The Mode Switch must be moved back to OPERATE for the new rate to be registered by the console.

C. Repeat with the Product Switch set to ALT-RATE. This will establish an alternate rate. D. Program the remaining channels, one at a time, using the procedure outlined in steps A through C above.

NOTE: Set the rates for granular co-applicators in Lbs/acre (Kg./Ha.). Set the rates for chemical injection pumps in oz./acre (L/Ha.). Set the rates for liquid channels in gallons per acre (L/Ha.).

2.4.4 SETTING PRODUCT DENSITY, CHANNELS 1, 2, 3 and L

In order to control accurately, the TASC controller requires a product density value for channel L (and for channels 1, 2, and 3 when they are set to the non-peristaltic or Flow mode). It is important to ensure the density is set correctly for the material you are applying.

A. Set the console switches to the following positions:

Power ON Mode Selector SET-UP Display Selector L & CHEMICALS, VOL. APPLIED Channel 1, 2, 3 or L Product SwitchON (CENTER) (one at a time)

B. Use the INC/DEC switch to set the density. Example cu25.0 for 25.0 pounds per cubic foot

(kg./0.1m3).

NOTE: If the channel is being used to control a liquid pump in the non-peristaltic or flow mode, set the density

to 1.0.

C. If no channel is selected or, if more than one channel is selected, the display will read Err.

2.5 SETTING THE % RATE CHANGE

This feature allows the operator to change application rates ON THE GO. Rates are changed with a simple actuation of the INC/DEC switch. The amount of change each switch actuation makes is the value set into the % RATE/SETUP position, (e.g. 20 =20% change in the target rate). For example, if the application rate (on channel C) is set to 400 Lb per acre, a single actuation of the INC switch will cause the rate to go to 480 Lb per acre (400 + 20% = 480).

A. Set the Console switches to the following positions;

Power ON Mode Selector SET-UP Display Selector % RATE

The display shows the current % change value.

B. Use the INC/DEC switch to set this number to the desired % change.

2.6 SETTING THE HOLD OR CLOSE RESPONSE OF CHANNEL C, L, 1, 2, & 3 CONTROL VALVES (Channels 1, 2, 3 in Flow Mode Only)

The operator has the option of selecting the response of the control valve, associated with each channel, to the "Booms OFF" condition. When the valve response CLOSE is selected, TASC closes the control valve when the booms are shut OFF. When the HOLD response is selected, TASC holds the valve in its current position when the

CE & S

TANDARD VERSION

2-4

TASC 6200/6500

Rev- 1

booms are turned OFF. HOLD is useful in maintaining pressure to the boom shut-off valves on a liquid control channel.

To check or change the valve response, use the following procedure:

A. Set the console switches as shown:

Power ON Mode selector SET-UP Display selector SCAN Booms OFF Product L, C, 1, 2, or 3 ON (CENTER) (one at a time)

The display will read HOLD or CLOSE. The response can be changed using the INC switch. (Hold the INC switch up until the display changes. The response shown on the display when the switch is released is the selected response for that channel.) There is no selectable response when the channel is in peristaltic or nonperistaltic mode.

B. If no channel is selected or, if more than one channel is selected, the display will read Err.

2.7 SETTING THE GROUND SPEED OVERRIDE SPEED (GSO)

The GSO function generates an operator selectable speed signal which TASC will use whenever the GSO switch is turned on and actual ground speed is less than the selected setting.

A. Use the following switch settings to enter the desired GSO speed.

Power ON Mode selector SET-UP

Display selector SPEED B. Use the INC/DEC switch to set the desired speed. C. The GSO speed will be used by TASC whenever the GSO switch is ON (closed) and the actual ground

speed is less than the GSO speed selected.

NOTE: If you do not have a GSO switch, the only way to turn GSO off is to set the GSO speed to zero. CAUTION: When traveling at a speed slower than the GSO speed setting, this feature causes the product to

be applied at a rate consistent with the GSO speed, rather than the true ground speed. Caution must be exercised when operating in this mode as serious over application can occur if not used properly. When GSO is being used, and the true ground speed is less than the pre-selected “GSO” speed, the console sounds an alarm and the display flashes a “Too Slow” message to warn the operator of possible over application.

2.8 SETTING THE TEST SPEED VALUE

The Test Speed function generates an operator selectable speed signal which TASC will use whenever the Display Selector Switch is set to the Test Speed position.

A. Use the following switch settings to enter the desired test speed.

Power ON

Mode selector SET-UP or OPERATE

Display selector TEST SPEED B. Use the INC/DEC switch to set the desired speed.

2.9 SETTING BOOM WIDTHS

TASC automatically compensates for changes in the swath width, caused by changing active boom sections. To do this, it is necessary for the operator to define the boom widths using the following procedure.

A. Set the Console switches to the following positions;

Power ON Mode Selector SET-UP Display Selector WIDTH All Boom Switches (external) OFF

The display cycles through each boom position and displays its current width.

B. As each boom position appears on the display, use the INC/DEC switch to set the display to the number of

inches (meters) covered by that boom section.

C. Set all unused boom sections (up to a total of nine) to a width of zero “0” inches (meters). This ensures that

an accidental boom switch ON signal does not affect application rates.

D. Finally, let the boom width display cycle through the boom sections until it shows Boom C. As the width of

C is displayed, it can also be changed with the INC/DEC switch. This value is used by the console to control the operating rate for each channel during calibration operations where the boom switches are normally OFF. This value is normally set to the total operating width of the entire applicator, in inches (meters).

E. When the boom widths are set turn all the live booms ON and return to the OPERATE mode, the new total

boom width is displayed in feet (meters). If this does not agree with your total boom width, check the individual boom widths again, (steps B and C).

2.10 DISTANCE CALIBRATION

The ground speed sensor must be calibrated to ensure accurate application rates. This calibration should be periodically checked, especially if the sensor has been moved or the tires have been changed.

2.10.1 INITIAL CALIBRATION SETTINGS

The following values will be close. Use them for the initial settings so you get an initial reading of distance during the calibration procedure.

NOTE: IT IS IMPORTANT TO FIELD CALIBRATE THE GROUND SPEED SENSOR TO INSURE OPTIMUM ACCURACY.

MID-TECH COMPACT RADAR - 779 DICKEY- john RADAR - 1000 WHEEL SENSOR - 3500 SPEEDOMETER SENSOR - 3500

place to maneuver the vehicle. The longer the distance, the more accurate the test. C. Drive to the starting point and STOP. Make sure all booms are OFF. Turn ON the TASC power switch. D. Turn the display selector to DISTANCE and put the mode selector in SET-UP. The TASC displays the

current distance calibration number. Record this number for reference.

E. Put the mode selector switch to the OPERATE position and use the DEC switch to set the accumulated

distance reading to ZERO. (If the console shows a distance being accumulated while the vehicle is station-

ary, the radar is vibrating. Change engine RPM or install dampening material under the radar mounting

bracket to stop the vibration.)

F. Drive the vehicle to the other end of the measured distance using a speed of five to ten miles per hour (ten to

fifteen kilometrs per hour). Stop at the end marker.

G. The TASC displays the accumulated distance. Compare the accumulated distance to the measured distance,

if they are the same, calibration is complete. If they are different, correct as follows: H. Calculate the new calibration number using the formula:

(ACTUAL DISTANCE ÷ DISPLAYED DISTANCE) X CALIBRATION NUMBER = NEW CALIBRATION NUMBER. (If the distance shown on the console is greater than the actual distance, the calibration number will decrease.

98-05019

Use the INC/DEC switch to change the distance calibration number, in the SET-UP mode, until

the displayed distance in the OPERATE mode is the same as the actual distance.

RECORD THE DISTANCE CALIBRATION NUMBER HERE

2.11 CALIBRATION OF CHANNEL C

Channel C is typically a granular channel. It may be necessary to adjust the calibration number in the TASC console to ensure an accurate output from the machine. If applying a granular product the calibration number represents the number of sensor pulses per cubic foot of material discharged. If applying a liquid product the calibration number represents the number of sensor pulses per gallon of material discharged.

The conveyor must be calibrated whenever there are changes to the discharge gate openings. (NOTE: Other

factors, such as moisture content, granule size, granule shape, etc., may also affect this constant.)

THE CALIBRATION PROCEDURE IS SIMPLE. IT IS IMPORTANT TO CALIBRATE FOR THE MATERIAL AND GATE OPENINGS YOU ARE USING. Be sure you have entered the proper PRODUCT DENSITY (SEE

2.4.2).

A. Use the following switch settings.

Power ON

Mode selector SET-UP

Display selector CARRIER, VOL. APPLIED

Booms ON (if channel is in split drive)

Channel C Product switch ALT. RATE

The display shows the current calibration number. Record for reference. Turn the booms OFF.

B. Weigh the machine and load. Back up to a location where you can safely collect the discharged material.

2-7

CE & STANDARD VERSION

98-05019

TASC 6200/6500

Rev- 1

C. Set an application rate similar to one you would use in the field (see 2.4.1). Zero the accumulated volume

for Channel C (see 3.1.4).

D. Set a normal field speed into the TEST SPEED position (see 3.7). Select TEST SPEED and OPERATE

mode. Turn the channel C product switch and the booms ON. The machine will begin to discharge product.

E. Discharge enough material to get an accurate measurement. For example: if your scale reads in 20 lb (10 kg)

increments, you must discharge at least 2000 lbs (1000 kg) to be able to measure within 1% accuracy.

F. When enough material has been discharged, switch the booms OFF and rotate the display selector to

CARRIER, VOL. APPLIED. TASC displays the calculated amount discharged by the machine, in pounds (kg).

G. Weigh the truck and load (be sure the driver is included if he was in the truck when it was weighed the first

time). The difference between the starting weight and the ending weight is the actual amount discharged.

H. To correct the calibration number, use the following formula:

(INDICATED WEIGHT ÷ ACTUAL WEIGHT) X CAL # = NEW CAL #. If the weight read from the console is greater than the weight actually measured, the calibration number will increase.

I. Put the mode selector switch in SET-UP and the C Channel Product Switch in ALT. RATE. (IF YOU ARE

IN SPLIT DRIVE, YOU MUST HAVE ALL THE PROGRAMED BOOM SECTIONS TURNED ON.) Use the INC/DEC switch to change the calibration number. Turn all booms OFF. Switch back to OPERATE and the corrected indicated weight is displayed. If the indicated weight now matches the actual weight, the machine is calibrated.

FOR GRANULAR PRODUCTS WRITE DOWN THE CALIBRATION NUMBERS FOR DIFFERENT MATERIALS AND DIFFERENT GATE SETTINGS. USE THOSE NUMBERS WHENEVER YOU ARE SPREADING THAT MATERIAL AT THE SAME GATE SETTING.

Note: If channel C is being used as a liquid control channel, start with the typical flow meter calibration

number for the flow meter installed. Adjust the calibration number according to the testing and adjustment procedure in Section 2.12 except the C channel switch is turned on instead of the L channel switch.

NOTE: Channel C Product Density must be set to 1.0 to use it as a liquid control channel (See Section

2.4.2)

IF IT IS NOT CONVENIENT TO CONDUCT AN ACTUAL CATCH TEST, FIELD EXPERIENCE WILL ALLOW YOU TO FINE TUNE THE CALIBRATION NUMBER. IF CHANNEL C IS APPLYING TOO MUCH, DECREASE THE CALIBRATION NUMBER BY THE SAME PERCENTAGE AS THE OVER APPLICATION. IF CHANNEL C IS APPLYING TOO LITTLE (YOU HAVE MATERIAL LEFT OVER) INCREASE THE CALIBRATION NUMBER BY THE SAME PERCENTAGE AS THE UNDER APPLICATION.

2.12 CALIBRATING THE L CHANNEL

It may be necessary to adjust the L Channel calibration number to get an accurate application.

When used as a liquid control channel the density must be set to 1.0 and the initial calibration number represents

* Raven flow meters, use the factory calibration number divided by 10. All other flow meters, use the manufacturers' supplied information regarding the pulses per gallon.

When being used to control a granular product set the product density, using the procedure outlined in section 2.4.4, and enter an initial calibration number, which represents pulses/ft3, using the procedure outlined below to do a calibration test.

A. Use the following switch settings to start the calibration:

Power ON

Mode selector SET-UP

Display selector L & CHEMICALS, VOL. APPLIED

Booms ON (if channel is in split drive)

Channel L Product SwitchALT. RATE

TASC will display the current calibration number for channel L. Record for reference. The INC/DEC

switch is used to change this number.

B. Move the Mode Switch to OPERATE and use the DEC switch to set the accumulated total to zero.

C. Use a catch test (or weight loss test) to fine tune the calibration. Divert channel L output to an appropriate

catch basin. If calibrating for liquid operation, route material through an adjustable pressure relief valve or

manually operated throttling valve. D. Rotate the display selector to TEST SPEED and turn ON the booms. Channel L begins to discharge. When

sufficient material has been collected, turn OFF the booms and rotate the display selector to L & CHEMI-

CALS, VOL. APPLIED.

E. The TASC console displays the calculated amount of discharge. Measure the amount actually discharged.

Correct the calibration number using the following formula:

(INDICATED AMOUNT ÷ MEASURED AMOUNT) X CALIBRATION NUMBER = NEW CALIBRATION NUMBER. If the amount read from the console is greater than the measured amount, the calibration number will increase.

F. Set the L Channel Product Switch to ALT. RATE and the Mode Selector switch to SET-UP (if console is

being operated in Split Drive all active booms must be ON), and adjust the calibration number using the

INC/DEC switch. Turn booms off. Return the mode selector to OPERATE and TASC should display the

amount actually measured. The calibration is complete.

CALIBRATING WITH WATER WILL BE SUFFICIENT FOR MOST MATERIALS; HOWEVER, FACTORS SUCH AS VISCOSITY AND DENSITY CAN SLIGHTLY AFFECT THE CALIBRATION. FOR MATERIALS THAT ARE MUCH DIFFERENT THAN WATER, THE CHANNEL SHOULD BE CALIBRATED WITH THE MATERIAL TO BE APPLIED.

2.13 CALIBRATING PRODUCTS 1,2 AND 3 (TASC 6500 ONLY)

Channels 1,2 or 3 can be used as either liquid injection channels or granular co-applicator channels. The calibration methods are similar. It is necessary for you to be able to catch and measure the discharge from each channel.

NOTE: If you are using channels 1, 2, or 3, in "Flow Mode" follow the procedure in section 2.12 to calibrate except the desired channel switch (1, 2, 3) must be turned on instead of the L channel switch.

2.13.1 CALIBRATING MID-TECH

If you are using a MID-TECH® injection pump, use the following calibration numbers to get started. (Be sure the channel is set to peristaltic drive, section 2.2 of the manual.)

The following values are typical calibration numbers (PC#’s) you can expect to see on MID-TECH injection pumps after performing the field calibration procedure. If your pump calibration number differs from the typical range, check the calibration. Enter these numbers for your initial pump calibration numbers, before conducting the actual prime or pump calibration procedure.

independently using this procedure.

2.13.2 CALIBRATING GRANULAR BIN APPLICATORS

The first step in calibrating the feed mechanism of the granular co-applicator bin is to enter the initial calibration number supplied by the equipment manufacturer. If an initial number is not available, you can estimate an initial calibration number by the following method.

For U.S. Units: Divide the weight discharged (in pounds) during one revolution of the feed mechanism by the number of sensor pulses generated during each revolution. Multiply the result by 1,000,000 and divide that result by the product density (in pounds per FT

For metric units: Divide the weight (in kilograms) discharged during one revolution of the feed mechanism by the number of sensor pulses generated during each revolution. Multiply the result by 3,575,000 and divide that result by the product density (in kilograms per tenths of a M3). Use this number for the initial calibration.

). Use this number for the initial calibration.

For Air Max co-applicator bins, use the following initial calibration numbers:

HIGH RATE ROLLER LOW RATE ROLLER

(deep grooves) (shallow grooves)

-800 -400

With all boom sections OFF, check to see that the proper calibration numbers and constants are entered in the console. Pay particular attention to the density factors. Refer to the calibration section of the manual for specific help.

3.1.2 APPLICATION RATES

With all boom sections OFF, and the MODE SELECTOR switch in the SET-UP position, review the application rates for each control channel. Remember to check the alternate rates also.

3.1.3 ACCUMULATED AREA

The area accumulators can be reset to zero by selecting AREA and holding the DEC switch down until the display resets to zero. There are two accumulators, one in the OPERATE mode and one in the SET-UP mode. The accumulators are zeroed independently. Keep track of field area in OPERATE/AREA and keep track of total area in SET-UP/AREA.

3.1.4 ACCUMULATED AMOUNTS

Check the accumulated total discharge from each channel by viewing CARRIER, VOL. APPLIED or L & CHEMICALS, VOL. APPLIED, while in the OPERATE mode. Use the DEC switch to reset to zero.

3.1.5 OPERATE

The TASC system is ready to start applying. Set the MODE SELECTOR switch to OPERATE. Turn ON the proper product switches. Select an appropriate display function, SCAN for example.

3.1.6 CHECK THE VEHICLE

Make sure the hydraulics (or liquid) pumps are engaged and operating normally.

3.1.7 START APPLYING

Drive the vehicle toward the application area and turn booms ON to start applying. TASC automatically controls application of the selected channels. Area and amounts applied will begin to accumulate. The console will display actual application rates.

3.1.8 STOP APPLYING

Reaching the end of the field, turn the booms OFF. The application stops. After the vehicle has turned, switch the booms back ON to continue application.

3.2 GROUND SPEED OVERRIDE (GSO)

An optional ground speed override switch can be used to operate the machine using the GSO speed. Ground speed override is used to bring the applicator channels on line quickly when starting from a dead stop. Ground speed override will also ensure a minimum acceptable pattern when the vehicle is maneuvering at very low ground speeds. GSO can also be used to flush the applicator from the cab, with the vehicle stopped.

The TASC system operates normally when the GSO switch is in the OFF (open) condition. When the GSO switch is ON (closed), and the actual ground speed is less than the GSO speed, TASC uses the GSO speed to control the product flow rates. When the actual ground speed increases above the preset GSO speed, TASC controls flow rates using the actual ground speed. See the following table for a better example of GSO operation.

GSO GSO speed GROUND SPEED TASC CONTROL

OFF 5 MPH (KPH) 6 MPH (KPH) 6 MPH (KPH) OFF 5 MPH (KPH) 4 MPH (KPH) 4 MPH (KPH) ON 5 MPH (KPH) 6 MPH (KPH) 6 MPH (KPH) ON 5 MPH (KPH) 4 MPH (KPH) 5 MPH (KPH)

CAUTION: When traveling at a speed slower than the GSO speed setting, this feature causes the product to be applied at a rate consistent with the GSO speed, rather than the true ground speed. Caution must be exercised when operating in this mode as serious over application can occur, if not used properly. When GSO is being used, and the true ground speed is less than the pre-selected “GSO” speed, the console will sound an alarm and the display will flash a “Too Slow” message to warn the operator of possible over application.

3.3 CHANGING ACTIVE BOOM SECTIONS

The active boom sections can be changed at any time by turning the boom switches ON or OFF. The TASC automatically adjusts application flow rates to account for the change in width. Area accumulators and total applied accumulators are also adjusted automatically for the change in width. When all boom sections are turned OFF, application stops.

3.4 CHANGING APPLICATION CHANNELS

The TASC console allows the operator to start and stop the application of individual products "ON THE GO". When a Product Switch is turned OFF, the flow of material stops and the totals accumulator for that channel stops. If any of the other Product Switches are still active however, the area accumulators continue to count area.

3.5 CHANGING APPLICATION RATES ON THE GO

The TASC console allows the operator to change the rates of any or all of the Products "ON THE GO". The change can be to a predetermined rate or, using the INC/DEC switch, percentage changes can be made.

3.5.1 ALTERNATE APPLICATION RATES FOR EACH CHANNEL

An alternate application rate can be selected for each channel using the ALT-RATE position on its Product Switch. Selection of an alternate rate for one channel does not affect the rates of the other channels. The TASC system will continue to apply material at the alternate rate until the Product Switch is returned to the normal ON position.

The programmed rates and alternate rates can be viewed with the vehicle stopped, booms OFF, and the TASC console in the OPERATE or SET-UP modes. Turn the display selector to L & CHEMICALS, APPL. RATE and select one of the product switches 1,2,3 or L. Switching the rate selection switch for that channel between ON and ALT-RATE displays both preset rates. To view the rates set for the C product, turn the display selector switch to CARRIER, APPL. RATE and select ON or ALT-RATE with C Product Switch. Normal and alternate rates can be changed in the SET-UP mode using the INC/DEC switch.

CAUTION: Operating in an alternate application rate is not a normal condition. The TASC console will continue to remind the operator that a non-standard rate has been selected. TASC will flash the channel indicator light and display a flashing RATE message on the display.

3.5.2 CHANGING THE PERCENT RATE ON THE CARRIER CHANNEL ONLY

The TASC console allows the operator to change the application rate of the C channel product by a percentage amount using the INC/DEC switch. The change does not affect the other products. The percentage change affects either the normal or alternate rate of the channel, depending on which has been chosen with the Product Switch.

The operator selects the CARRIER, APPL. RATE position while in the OPERATE mode. The console displays the actual application rate while applying (or the target rate with the vehicle at rest). Toggling the INC/DEC switch changes the channel rate up or down by the percentage set in the % RATE/SET-UP position. The display momentarily shows the new target rate of channel C before displaying the actual discharge rate. The percent rate change is canceled by switching out of the CARRIER, APPL. RATE function.

CAUTION: Operating with a modified application rate is not a normal condition. The TASC will continue to remind the operator that a non-standard rate has been selected. TASC will beep an alarm and display a flashing % RATE message on the display.

3.5.3 CHANGING THE PERCENT RATE OF CHANNELS 1, 2, 3 AND L SIMULTANEOUSLY

The TASC console allows the operator to change the application rate of channels 1,2,3 and L by a percentage amount using the INC/DEC switch. The change does not affect channel C. The percentage change does affect either the normal or alternate rate of each channel, depending on which has been chosen with the Product Switch.

The operator selects the L & CHEMICALS, APPL. RATE position while in the OPERATE mode. The console displays the actual application rates while applying (or the target rates with the vehicle at rest). Toggling the INC/DEC switch changes rates up or down by the percentage set in the % RATE/SET-UP position. The display momentarily shows the new percentage target rate before displaying the actual discharge rates. The percent rate change is canceled by switching out of the L & CHEMICALS, APPL. RATE function.

CAUTION: Operating with a modified application rate is not a normal condition. The TASC console will continue to remind the operator that a non-standard rate has been selected. TASC will beep an alarm and display a flashing % RATE message on the display.

3.5.4 CHANGING THE PERCENT RATE OF ALL CHANNELS SIMULTANEOUSLY

The TASC console allows the operator to change the application rate of all channels by a percentage amount using the INC/DEC switch. The percentage change affects either the normal or alternate rate of each channel, depending on which is chosen with the rate selector switch.

The operator selects the % RATE position while in the OPERATE mode. The console displays 100. Toggling the INC/DEC switch changes all rates up or down by the percentage set in the % RATE/SET-UP position. The display shows the new percentage target. The percent rate change is canceled by switching out of the % RATE function.

CAUTION: Operating with a changed application rate is not a normal condition. The console will continue to remind the operator, that a non-standard rate has been selected. TASC will beep an alarm and display a flashing % RATE message on the display.

3.6 MANUAL OVERRIDE OF CONTROL VALVE

Sometimes it is necessary to manually override the control valves. This feature is useful for stationary unloading of the vehicle or for priming of the liquid pump when first starting the machine. TASC allows the control valves on flow channels to be overridden easily.

3.6.1 OVERRIDE CHANNEL C CONTROL

Select the CARRIER-Appl. Rate position with the Display Selector switch while in the SET-UP mode with all booms OFF. Set the C Product Switch to the center ON position. Use the DEC switch to zero the channel C application rate. Switch the mode selector to OPERATE. The display shows "Flow Contl OFF Auto". Channel C flow control valve now responds to toggling of the INC/DEC switch. INC opens the valve and DEC closes the valve. The switch must be held for a few seconds for the valve to open or close all the way. NOTE: The Display Selector must remain in the CARRIER-APPL. RATE position.

When the booms are turned on and there is some ground speed, the actual application rate of the C channel will be displayed.

Re-entering an application rate for channel C causes the TASC to resume normal operation.

3.6.2 OVERRIDE CHANNEL L, 1, 2, & 3

(Channels 1, 2, and 3 "Flow Mode" only)

While in the SET-UP mode, select the L & CHEMICALS, Appl. Rate position on the display selector switch. Turn the product switch, for the desired channel, to the center ON position. Use the DEC switch to zero the channel application rate. Switch the mode selector to OPERATE. The display shows "Flow Contl OFF Auto". The control valve, for the chosen channel, now responds to toggling of the INC/DEC switch. INC opens the valve and DEC closes the valve. The switch must be held for a few seconds for the valve to open or close all the way.

To view the actual application rate of the L channel while in the manual override mode, the booms must be on and there must be some ground speed.

Re-entering an application rate for the channel causes the TASC to resume normal operation.

3.7 SETTING TEST SPEED

The TASC console provides a simulated speed signal which can be used for stationary testing (see calibration procedures - sect. 2.11, 12, 13) or in emergencies when the vehicle speed sensor fails (see Emergency Operations - sect. 6.1).

4.0 MAINTENANCE

Maintenance is a matter of common sense. Here are a few tips.

SOAP

4.1 FLUSHING AND CLEANING

It is important to keep the chemical applicator clean. Chemicals are becoming more and more potent and environmental considerations are becoming more demanding. Keeping the equipment clean also makes it easier to maintain the vehicle and increases its working life.

Always refer to the chemical manufacturer's directions regarding cleaning and flushing. For example; if the manufacturer requires a triple rinsing, then all parts of the applicator that have come in contact with the chemical must be triple rinsed with clear water. If the manufacturer requires rinsing with a special solution, then all parts of the applicator that have come in contact with the chemical should be rinsed with the solution. As a general rule, MIDWEST TECHNOLOGIES recommends the following:

WARNING: Failure to follow the manufacturer's recommended cleaning and flushing procedures may result in chemical damage to crops receiving later treatment. All flushed material must be collected and disposed of in accordance with the applicable federal, state, and local regulations for your area.

1. Do not leave chemical in injection or application lines overnight. The system should be flushed and cleaned at the end of each day's operation. Some chemicals can bind to the walls of the containers and lines. The longer the chemical is in contact, the greater the possibility this will occur. Bound chemical has been known to release during subsequent application operations, seriously affecting the crop being treated. Flushing and cleaning so that chemical is not left in the sprayer for long periods of time makes this less of a concern.

2. All injection pumps should be flushed daily, regardless of use. Exercising the pumps is good for them. It helps to keep pumps in good working order. Also, unless the pump has a positive shut off valve, some of the chemical applied that day may migrate up the injection line. Flushing all the injection pumps helps guard against contamination.

4.2 TASC CONTROL CONSOLE

The TASC console requires no maintenance other than general cleanliness and auditing the constants stored in memory. The console can be kept clean by wiping with a damp cloth. Unused connectors should be covered with the dust covers provided. The constants can be monitored by checking each of the calibration constants and each of the desired application rates.

TASC uses non-volatile memory to store constants. It is unlikely there will be a need to reenter constants, however, there have been rare cases of constants being changed as a result of random electrical interference. For this reason, MIDWEST TECHNOLOGIES strongly recommends keeping a written record of the calibration constants. Check daily, before commencing applications.

4-1

CE & STANDARD VERSION

98-05019

TASC 6200/6500

Rev- 1

4.3 GROUND SPEED SENSOR

4.3.1 WHEEL SENSOR

Check the sensor daily for loose or bent fittings. Mud or trash can push the sensor out of alignment or knock magnets off. Repair or replace any damaged parts immediately and calibrate the sensor.

4.3.2 RADAR SENSOR

Check the sensor daily to make sure its face is clean and the mounting bracket and hardware is tight. The sensor can be wiped clean with a damp cloth. If it is suspected that the radar sensor mounting position has shifted, the mounting bracket must be tightened and the sensor must be calibrated.

CAUTION: While inspecting and cleaning the radar speed sensor, do not look directly into the face of the unit. The radar generates a low level microwave signal which could be dangerous to the eyes.

4.4 FLOW METER

Prior to each day's application, inspect the flow meter to be sure there are no leaks around its fittings. At the end of the day, take care to thoroughly flush the flow meter with clean water.

BE CAREFUL THAT WATER OR SEDIMENT IS NOT TRAPPED IN THE FLOW METER, PARTICULARLY IN COLD WEATHER, AS DAMAGE TO THE MECHANISM CAN OCCUR.

The flow meters supplied by MIDWEST TECHNOLOGIES are inherently rugged but continued use will eventually wear the internal bearings and shafts until the meter becomes inaccurate. Repair kits are available to repair the meters.

4.5 HYDRAULIC FLOW CONTROL VALVES

The most critical maintenance item for the hydraulic valves is the hydraulic oil filter. Keep the filters clean and always use a good grade of replacement oil. Also do a daily check of the oil cooler heat exchanger to be sure it has a good flow of air. Cool oil lasts longer and performs better.

Some valves have a removable cover over the motor actuator. Be sure the cover is secure and that any gaskets are in place.

4.6 LIQUID FLOW CONTROL VALVES

Inspect the liquid flow control valve before each day's operation. Look for leaks around the attachment fittings and valve stems. If the valve has a removable cover over the motor actuator, be sure the cover is secure and that any gaskets are in place.

At the end of the day, care should be taken to thoroughly flush the valve with clean water.

BE CAREFUL THAT WATER OR SEDIMENT IS NOT TRAPPED IN THE FLOW CONTROL VALVE, PARTICULARLY IN COLD WEATHER, AS DAMAGE TO THE MECHANISM CAN OCCUR.

4.7 ROTATIONAL SENSORS

Periodically check rotational sensors to make sure that they are secured tightly to the shafts being measured. Also check the torsion strap on slotted disc sensors to be sure it is not damaged or loose. Be sure the mounting brackets for proximity sensors have not been bent or damaged. Replace any damaged parts immediately and calibrate the associated channel.

4.8 MID-TECH PERISTALTIC LIQUID INJECTION PUMPS (TASC 6500 ONLY)

4.8.1 DAILY

Clean and lubricate the flexible tubing in the injection pumps prior to each day's operation. Use only the tube lube from your supplier.

Check the calibration of the injection pumps. Calibration numbers will change as the pumps and tubes age.

At the end of the day, disconnect the pump from the MID-TECH TANK chemical tank), connect the pump to fresh water and flush according to the chemical manufacturers's directions.

CAUTION: BE SURE THE CHEMICAL LINES ARE DISCONNECTED OR THE TANK VALVES ARE OFF, SO THAT LIQUIDS CAN NOT DRAIN OR SIPHON INTO THE MAIN BOOM SUPPLY LINE WHEN THE TUBES ARE REMOVED FROM THE INJECTION PUMP.

Then, remove the tube from the pump housing to prevent it from developing a hard spot under the roller. This is particularly important in cold weather, or when the pump will be idle the next day.

4.8.2 WEEKLY

Check the flexible tubing for wear. Look for cracking, side splits or other signs of material fatigue. Damaged tubing must be replaced immediately. When tubing is replaced, the pump should be calibrated. Replacement tubing kits are available through your MID-TECH dealer.

4.8.3 SEASONAL

Replace the flexible tubing before application season begins each year. Calibrate the pump at the start of each season.

Check calibration whenever it is suspected the system accuracy has deteriorated, or anytime tubing is changed.

4.9 OTHER INJECTION PUMPS (TASC 6500 ONLY)

CAUTION: BE SURE THE CHEMICAL LINES ARE DISCONNECTED OR THE TANK VALVES ARE OFF, SO THAT LIQUIDS CAN NOT DRAIN OR SIPHON THROUGH THE PUMP INTO THE MAIN BOOM SUPPLY LINE.

At the end of the day, disconnect the pump from the tank (or turn OFF the valve at the outlet of the chemical tank), connect the pump to fresh water and flush according to the chemical manufacturer's directions.

4.9.1 SEASONAL

Calibrate the pump at the start of each season.

4.9.2 PERIODIC

Check calibration whenever it is suspected the system accuracy has deteriorated.

4.10 WIRING HARNESS

Inspect the external cabling for abrasion, stretched or pinched wires. If such a condition is seen, reroute the cabling and wrap it to protect it from further damage. If a broken wire is found, temporarily repair it by stripping the wire back on either side of the break, twisting it together and soldering the connection (USE ONLY ROSIN CORE SOLDER). The bare connection must be well insulated with heat shrinkable tubing or electrical tape.

MID-TECH strongly recommends replacement of damaged cables as soon as possible. Once a cable is damaged, moisture and chemicals can work their way under the insulation and cause corrosion to the conductor. In the end, continued problems will be experienced until the cable is replaced.

Periodically inspect the connectors on all cables. Use a non-lubricating spray solvent to clean connectors. Lubricating sprays leave a film which collects dirt and can eventually lead to connector failure. Clean connectors with a soft swab, like a Q-TIP. Do not use abrasive materials to clean connector contacts.

Check all fuses and fuse holders for any signs of corrosion and clean as necessary. There are fuses on the power connections at the battery, some boom control cables have a fuse for each boom section, and some of the newer motorized boom valves have fuses in the connector cables.

MIDWEST TECHNOLOGIES has gone to great lengths to make the TASC System as foolproof and reliable as possible. However, we recognize that things break from time to time, despite our best efforts. If the operator does experience a failure of the ground speed sensor, the main flow control valve, or, the flow meter, or rate sensor, the first thing to do is to carefully check the wiring harnesses for obvious breaks and follow the suggested troubleshooting advice outlined in Section 6.0. in this manual. Assuming there is no success in attempts to get the failed component to respond, MIDWEST TECHNOLOGIES suggests the following procedures, as a temporary measure, until the component can be fixed or replaced.

If the operator chooses to follow one of the following procedures, he should recognize that the accuracy of application is reduced. If this reduced accuracy is acceptable, these procedures will allow the operator to continue on a temporary basis.

6.1 GROUND SPEED SENSOR FAILURE

The Control Console has an internally generated speed signal when operated with the "GROUND SPEED OVERRIDE" function activated. When the unit is operated in the GSO speed mode, the Control Console will establish the APPLICATION RATE as if the vehicle were actually moving across the field at the programmed GSO speed, even though there is no real speed input. This feature can be used to operate the machine under a reduced accuracy, in the event of a failure of the speed sensor.

A. Disconnect the speed sensor cable from the back of the TASC console.

B. With all boom section switches OFF, Power ON, Mode Selector in the SET-UP position and the vehicle stopped, rotate the Display Selector to the SPEED position. Using the INC/DEC switch, set the ground speed override speed for the normal spraying/spreading speed, (See Section 2.7. for additional information).

C. Set the Mode Selector switch back to OPERATE. Start the vehicle and steer toward the desired swath, accelerating to normal application speed (as close as possible to the GSO speed value). As the vehicle reaches the start of the desired swath, turn on the booms and begin applying. IF YOU HAVE A GSO SWITCH, BE SURE IT IS TURNED ON.

D. The Control Console will control application as if the vehicle were moving at the established GSO speed. The actual accuracy of application will therefore depend upon the ability of the operator to maintain the desired vehicle speed. If the vehicle is traveling at exactly the established GSO speed, the application will be nearly exact. If the vehicle is traveling faster or slower than the established GSO speed, the APPLICATION RATE will be under or over the desired rate by a proportional amount.

E. The console will still keep track of the TOTAL APPLIED, and the system will adjust to changes in boom width. These functions can be monitored on the display.

F. The TASC display will continue to flash a too slow message, and an audible alarm will sound ,to indicate abnormal operation. There will be no SPEED displayed. AREAS will not accumulate. APPLICATION RATE information is meaningless.

MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE ONLY AS AN EMERGENCY, TEMPORARY PROCEDURE. THE PROBLEM WITH THE GROUND SPEED SENSOR SHOULD BE RESOLVED AS SOON AS PRACTICAL SO THAT FULL CONTROL OF THE APPLICATOR CAN AGAIN BE ENJOYED.

6.2 FLOW CONTROL VALVE FAILURE (LIQUID APPLICATOR)

The TASC System can be operated at a reduced level of control in the event of a flow control valve failure. To operate the sprayer, it will be necessary to manually adjust the flow control valve so that sufficient pressure is available to the booms to give a good spray pattern. Thus, there is no longer positive control over the flow. Use the following procedure to manually position the flow control valve.

NOTE: If the TASC console is connected to a Data Link, verify that the Data Link is set to LOCAL CONTROL. If it is not, switch the Data Link to LOCAL CONTROL and turn the TASC console OFF and back ON.

A. With the vehicle stopped, turn all boom sections OFF, set the product switch to the ON (center) position, and the mode switch to SET-UP (See Section 2.4). Use the INC/DEC switch to set the application rate to 0.0. Return the mode switch to OPERATEand set the Product Switch to the ON or ALT. RATE position (to view application rate).

B. Remove the fuse for the flow control valve at the cable disconnect. If the valve has failed in an open position, allowing sufficient flow to pass to keep a good pattern at the nozzles, no further action is needed to adjust the valve. If the valve has failed in a closed or nearly closed position, it will be necessary to remove the electric actuator assembly and manually rotate the valve stem to an open position. BE CAREFUL. MARK THE VALVE POSITION TO START. TYPICALLY FULL OPEN TO FULL CLOSE IS ONLY A 90 hydraulic control valve to regulate the pump speed, loosen the locking collar at the base of the actuator, and rotate the complete actuator until the desired boom pressure is achieved. Retighten the locking collar.

C. Turn ON the normal boom sections. Use a nozzle chart to determine the boom pressure that will give the desired APPLICATION RATE at the target speed. Adjust the pump bypass valve (if one is provided) or manually turn the control valve stem to generate the desired boom pressure. Turn all boom sections OFF.

D. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired swath, turn on the appropriate boom switches and the sprayer will start to spray. At this point, the operator is enjoying some monitoring functions of the TASC, but has no positive control of the flow control valve.

E. Monitor APPLICATION RATE. Actual APPLICATION RATE will be displayed. Adjust the ground speed to reach the APPLICATION RATE desired.

F. The console cannot automatically adjust for changes in boom widths. If booms are shut off, pressure must be reset. VOLUMES and AREAS will accumulate normally. SPEED will read correctly.

MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE ONLY AS AN EMERGENCY, TEMPORARY PROCEDURE. THE PROBLEM WITH THE FLOW CONTROL VALVE SHOULD BE RESOLVED AS SOON AS PRACTICAL SO THAT FULL CONTROL OF THE SPRAYER CAN AGAIN BE ENJOYED.

6.3 FLOW METER FAILURE (LIQUID APPLICATOR)

Channels C, L (1, 2, 3 in Flow Mode only)

The procedure is very similar to operating without the flow control valve except , in this instance, the flow control valve is cycled using a manual override procedure.

NOTE: If you are operating under GPS, first return the console to Local Control as described in the note in section 6.2.

A. Shut all boom sections OFF and stop the vehicle. Disconnect the flowmeter wiring harness at the sensor (3 pin connector).

B. Set the application rate to 0.0 (see sect. 2.4) and return the Mode Selector to OPERATE. The Flow Control Valve will now respond only to manually activated INC/DEC commands from the Control Console.

C. Turn ON the normal boom sections and allow spray. Use a nozzle chart to determine the boom pressure that will give the desired APPLICATION RATE at the target speed. Adjust the boom pressure using the INC/DEC switch on the Control Console. INC will open the Flow Control Valve and DEC will close the valve. Once the desired pressure is attained, turn all boom sections OFF.

D. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired swath, turn on the appropriate boom switches and the sprayer will start to spray. At this point, the operator is enjoying some monitoring functions of the TASC 6500, but has no automatic control of the flow control valve.

E. Monitor SPEED. Adjust the ground speed to reach the target speed desired.

F. The console cannot automatically adjust for changes in boom widths. If booms are shut off, pressure must be reset using the INC/DEC switch.

NOTE: The display selector must be turned to the APPLICATION RATE position in order for the INC/DEC switch to control the valve. AREAS will accumulate normally and SPEED will read correctly.

MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE ONLY AS AN EMERGENCY, TEMPORARY PROCEDURE. THE PROBLEM WITH THE FLOW METER OR PRESSURE SENSOR SHOULD BE RESOLVED AS SOON AS PRACTICAL SO THAT FULL CONTROL OF THE SPRAYER CAN AGAIN BE ENJOYED.

6.4 APPLICATION RATE SENSOR FAILURE (GRANULAR APPLICATION)

The TASC Spreader System, suffering a rate sensor failure, can be operated in a manner similar to the previously described sprayer failure (section 6.3).

NOTE: If you are operating under GPS, first return the console to Local Control as described in the note in section 6.2.

A. Turn the Conveyor Switch OFF, so that no boom lights are lit, and stop the vehicle. Disconnect the rate sensor from the flow control harness (3 pin connector).

B. Set the application rate to 0.0 (see sect. 2.4) and return the Mode Selector to OPERATE. The Hydraulic Flow Control Valve will now respond only to manually activated INC/DEC commands from the Control Console.

C. Start the vehicle moving toward the swath to be covered. When the vehicle reaches the starting point of the desired swath, turn on the Conveyor Switch and the spreader will start spreading. At this point, the operator is enjoying some monitoring functions of the TASC, but has no automatic control of the hydraulic flow control valve. NOTE: On some systems, the hydraulic control valve is used to turn the spreader on and off. If this is the case, it will be necessary to hold the INC/DEC switch up to start spreading, and down, to stop spreading.

NOTE: The display selector must be turned to the APPLICATION RATE position in order for the INC/DEC switch to control the valve.

D. Monitor SPEED. Adjust the ground speed to reach the target rate desired. SPEED will read correctly and AREAS will accumulate normally. The Application Rate will not be displayed.

MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE RARY PROCEDURE. THE PROBLEM WITH THE RATE SENSOR SHOULD BE RESOLVED AS SOON AS PRACTICAL SO THAT FULL CONTROL OF THE SPREADER CAN AGAIN BE ENJOYED.

A.4 FUSES AND POWER CONNECTIONS

(See illustration below)

TASC uses the inherent capacitance of the vehicle battery to protect the electronics against voltage spikes and electrical ground reference variations. For this reason:

IT IS EXTREMELY IMPORTANT THAT ALL CONNECTIONS BE MADE DIRECTLY TO THE VEHICLE BATTERY. ON VEHICLES WITH MORE THAN ONE BATTERY, ALL CONNECTIONS SHOULD BE MADE TO THE SAME BATTERY.

All fuses will be located near the battery connection. TASC components use automotive type, in line fuses that are readily available from any auto parts store or most automotive repair facilities.

CAUTION !

CONNECT ALL POWER LEADS DIRECTLY TO THE VEHICLE BATTERY.
