98-05010 Rev. - 1 TASC-6000, 6300, 6600 2.0 CALIBRATION AND SET UP NOTE: PLEASE READ THROUGH THE FOLLOWING SECTIONS COMPLETELYBEFOREYOUBEGINCALIBRATION! The TASC Control Console must be calibrated for the various sensors used and programmed with certain information before it is ready to be used. The calibration and set up processes are not difficult, however; they must be followed precisely in order to get maximum accuracy out of the system. 2.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 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.). Power OFF Mode selector SET-UP Display selector DISTANCE B. Turn the rate selector switches, for any channels (1 - 6) that you want set to non-peristaltic to "ON". Any channels left "OFF" are set to the peristaltic mode. C. Hold the INC/DEC switch down while turning on the TASC power.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 The display shows the current Standard Application Rate (Oz/Ac or L/Ha) for Pump #1. B. Use the INC/DEC switch to set the value displayed to the desired rate. Example: 64.0 for 64 Fluid Oz. (2 qts.) per acre, (See Appendix A, Fluid Oz. Conversion Chart). Remember this is the actual chemical rate and bears no relationship to the carrier rate. C. Repeat steps A and B for the remaining injection pumps, turning off each pump off before setting the next one.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 2.5 SETTING BOOM WIDTHS The Mid-Tech TASC Control Console is designed to automatically compensate for changes in the swath width, caused by activating or deactivating separate sections of a multi-section spray boom. For the console to automatically respond to changes in swath width, it is necessary for the operator to set the individual boom section lengths into the console. Use the following procedure to define the boom lengths to the console. A.

98-05010 Rev. - 1 TASC-6000, 6300, 6600 F. Make sure there is enough liquid in the main tank to do the test; start the main carrier pump; rotate the display selector switch to TEST SPEED; turn ON the boom switch. Allow the sprayer to discharge until the desired amount has been pumped; turn OFF the boom switches. G. Rotate the display selector switch to CARRIER, TOTAL APPLIED. If the total shown on the console agrees with the total discharge actually measured, no further action is necessary.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B. Use the INC/DEC switch to select the initial distance calibration value suggested. You are now ready to perform the distance calibration. 2.7.2 DISTANCE CALIBRATION PROCEDURE The following procedure is recommended by MIDWEST TECHNOLOGIES for establishing an accurate distance calibration. NOTE: All pump and boom switches should remain OFF during the entire procedure. A. Fill the main tank 1/2 full of water, to approximate actual load conditions.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 2.8.1 TYPICAL PUMP CALIBRATION NUMBERS, PC# The pump calibration number (PC#) is a value that relates to the volume of chemical output during each revolution of the injection pump and is used by the TASC Control Console to determine each pump’s actual discharge rate. Pump calibration numbers will differ slightly from one pump to the next due to variations in plumbing, tube size, pump chambers, etc.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C. Use the INC/DEC switch to reset the display to zero. Select SET-UP with the Mode Selector switch. The current pump calibration number is displayed. Now go back to the pump and perform the flush operation. D. Disconnect the discharge line on the injection pump from the sprayer. (On most installations this can be accomplished by using a calibration valve to redirect the discharge flow.) E.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 N. REPEAT THIS PROCEDURE (steps B through M) FOR THE REMAINING PUMPS. O. Record the Pump Calibration Numbers Here: PUMP 1 PUMP 2 PUMP 3 PUMP 4 PUMP 5 PUMP 6 (NOTE: This calibration procedure can be conducted with one or more boom sections active.. This will not affect the accuracy of the calibration, however; the console will not allow any further operations until the active boom sections are turned "OFF".
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B. DIRECT MEASUREMENT OF THE “PRIME” VALUE Actually measuring the amount of fluid needed to prime the injection line is the second, and more accurate method, of determining the “PRIME” value. To do this, first calibrate each injection pump using the procedure outlined in Section 2.8.2.; then, operate the pump in a controlled manner, allowing its discharge to be collected and measured.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 L. Proceed to measure the prime values for the remaining pumps, in sequence, using the procedure outlined in items C through K above. M. When all measurements are complete, reconnect the pump discharge lines to the injection points in the main boom supply line. N. Use the procedure outlined in 2.8.4. below, to set the recorded “PRIME” values into the console. O.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 A. To select the desired response set the console switches to the following positions: Booms Injection pumps Power Mode Selector Display Selector OFF OFF ON OPERATE CARRIER, TOTAL APPLIED B. Holding the INC Switch up displays the current selected response. C. Continuing to hold the INC Switch up causes the display to cycle between the two options at about three second intervals. D. When the desired response is shown, release the INC switch. 2.9.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 CAUTION: When traveling at a speed slower than the GSO speed setting, this feature will cause the Product to be applied at a Rate consistent with the GSO speed, rather than the true ground speed, possibly resulting in serious over application.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 2.12.2. REFLOW SET UP Before operating the sprayer in the Reflow mode, there are some critical set-up steps which must be taken. 1. Using the methods recommended by the sprayer manufacturer, adjust the reflow bypass valves so that they will allow reflow at the same flow rate that the individual boom section would apply, if it were activated.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 The TASC Console display cycles through its normal Power Up testing routine and momentarily displays the software level installed. After about two seconds the display changes to "Stnrd", and remains in this condition until the DEC. Switch is released. The Console then displays the current Flow Meter Calibration Number. The TASC System is now back to its standard configuration. The system remains in standard until the Reflow Option is activated again. 2.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 3.0. OPERATION Under normal operating conditions, TASC is automatic. It performs precisely, according to the information and directions it receives from the operator. It is important to verify that TASC has the proper instructions before beginning spraying operations each day. 3.1. NORMAL START UP AND OPERATION A. CONSTANTS: With all boom switches in the OFF position, verify that the proper constants are still entered in the console. Refer to section 2.0.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 3.4. CHANGING THE APPLICATION RATE “ON THE GO” TASC allows the operator to change the Application Rate of the main carrier, or the rates of individual injected chemicals, “ON THE GO”, using the INC/DEC switch. The amount of change caused by each actuation of the INC/DEC switch is predetermined in the SET-UP Mode, (see Section 2.4). We will use an illustration to demonstrate the ability to change application rates "On The Go". 3.4.1.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 command is cancelled, TASC resumes controlling the injection application rate according to the target rate established by the procedure in Section 2.3.2 of the manual. Operation at a changed chemical injection rate is not a normal condition. TASC continuously alerts the operator that an abnormal rate function is been selected. The alert is both visual (a flashing “% RATE, Pump” on the LCD display ) and audible (a periodic “beeping” of the Sonalert). 3.4.2.2.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 3.6. GROUND SPEED OVERRIDE An optional Ground Speed Override Switch can be used to temporarily operate the sprayer using the "GSO Speed" instead of the actual speed registered by the Ground Speed Sensor, (See Sec. 2.10). The override feature is used to bring the sprayer on line quickly when starting from a dead stop or to maintain an adequate spray pattern when the vehicle is maneuvering at very low ground speeds.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 3.8. MANUAL OVERRIDE OF FLOW CONTROL VALVE There may be times when it will be necessary to control the product flow manually (To run "Speed & Pressure", unload the carrier tank, etc.). A. To enter this mode do the following: MODE SELECTOR SWITCH MODE SWITCH Use INC/DEC SWITCH to set rate to 0.0 MODE SWITCH CARRIER APPL. RATE SETUP OPERATE B. Console reads "Flow Contl OFF Auto". In this mode the Flow Control Valve only responds to the INC/DEC Switch.

98-05010 Rev. - 1 TASC-6000, 6300, 6600 4.0. MAINTENANCE Mid-Tech recommends the following maintenance to keep your TASC system operating at peak efficiency. 4.1. FLUSHING AND CLEANING NOTE: It is important to keep your chemical applicator clean. Chemicals are becoming more potent and environmental considerations are becoming more demanding. Keeping the equipment clean also makes it easier to maintain the vehicle and extends its working life.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 If the tubing has been changed, the pump must be calibrated to ensure system accuracy. Use the field calibration procedure specified in Section 2.8.2 of this manual to calibrate the pump. 4.2.2. SEASONAL PUMP MAINTENANCE Always replace the flexible pump tubing before beginning spraying operations each season. This is particularly important if the sprayer has been sitting idle for an extended period of time.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 BE CAREFUL THAT WATER OR SEDIMENT IS NOT TRAPPED IN THE FLOW METER, PARTICULARLY IN COLD WEATHER, AS DAMAGE TO THE MECHANISM MAY OCCUR. 4.6. FLOW CONTROL VALVE Prior to each day’s spraying, the flow control valve should be inspected to ensure there are no leaks around the attachment fittings. At the end of the day, care should be taken to thoroughly flush the flow control valve with clean water.

98-05010 Rev. - 1 TASC-6000, 6300, 6600 6.0. EMERGENCY OPERATIONS MIDWEST TECHNOLOGIES has strived to make TASC as fool proof and reliable as possible. However, we realize that problems can occur. If the operator is experiencing a failure of the ground speed sensor, the main flow control valve or, the flow meter, the first step is to carefully check the wiring harnesses for obvious problems and follow the suggested troubleshooting advice outlined in Section 5.0. in this manual.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 6.2. FLOW CONTROL VALVE FAILURE The TASC can still be operated in the event of a flow control valve failure. To operate the sprayer, it is 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 main carrier flow, but; the chemical injection control system continues to operate in a normal, fully controlled manner.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 E. Turn ON the desired chemical injection pumps, to the rate desired, proceed to the application area, accelerating to normal spraying speed. When the vehicle reaches the starting point of the desired swath, turn on the appropriate boom switches and the sprayer starts to spray. At this point, the operator is enjoying all monitoring functions of TASC, with the exception of Carrier Application Rate and automatic control of the flow control valve.

SYSTEM OVERVIEW Mid-Tech has drawn upon many years of experience in electronically controlled chemical application to design and build this spraying system. We rely on the experiences of our users as well as ourselves to help us continually improve our systems. Please contact us to let us know what you like or don’t like about the TASC. We appreciate your comments, and THANK YOU for purchasing a MIDWEST TECHNOLOGIES Total Application Sprayer Control (TASC). B.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B.1.2. HOW A TASC-6300 AND 6600 CONTROLS CHEMICAL APPLICATION RATE The theory behind controlled, chemical injection spraying is simple. Each chemical is stored in a separate container until it is actually applied. Chemical is injected into the carrier as needed using a precision metering pump. Injected chemical mixes rapidly and thoroughly with the carrier before it leaves the sprayer through the nozzles.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B.2. TASC SYSTEM COMPONENT PARTS There are seven major components in a complete TASC Injection Control System, a console, ground speed sensor, flowmeter, flow control valve, boom interface cable, chemical containers, and injection pumps. Each of these components is described below so that the operator, will have a general understanding of how each of the parts performs its job. Boom Interface Cable Speed Sensor ON OPERATE INC. OFF SET- UP DEC.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B.2.3. FLOW CONTROL VALVE TASC requires a flow control valve in the main boom supply line to provide automatic carrier control. This valve throttles the carrier flow in response to commands from the control console. To be effective in controlling carrier flow, the valve must be fast acting and precise in its movements. The flow control valve may take the form of a hydraulic flow control valve controlling the flow rate by controlling the speed of the product pump.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 B.2.7. CHEMICAL CONTAINERS MIDWEST TECHNOLOGIES has designed special chemical containers for use with chemical injection sprayers. These containers are available in either 7.5 gallon or 25.0 gallon capacities and can be equipped with optional agitation devices. The tanks are mounted in optional stainless steel racks and are easily removed from the vehicle for filling, cleaning or storage.
98-05010 Rev.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.0. INSTALLATION C.1. CONTROL CONSOLE INSTALLATION The Control Console should be located inside the vehicle cab, when possible. It can be mounted on or below the dash, or any other location where it is accessible to the operator without diverting or obstructing his view. The mounting bracket may be attached to the console with the mounting face of the bracket up or down as required. C.1.1.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.1.2. CONSOLE CABLE ROUTING Console Cable routing is important. There are up to eleven connector positions on the back of the console; Power, Pump Controls #1 to #6, Ground Speed, Boom I/O, Flow Control, and serial I/O. Depending on the TASC model, some connector positions may not be present.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.2. FLOWMETER INSTALLATION The installer should refer to the detailed instructions shipped with the particular device being installed. MIDWEST TECHNOLOGIES recommends that these specific installation instructions be attached to this manual for future reference. There are, however, a few general mounting tips which should be considered for any flowmeter installation. The accuracy of the flowmeter depends on a smooth, unobstructed flow through the device.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.3. FLOW CONTROL VALVE INSTALLATION There are a number of different types of flow control valves capable of operating with the TASC System. The installer should refer to installation instructions supplied with each device for information that applies specifically to that device. Mid-Tech recommends that these specific installation instructions be attached to this manual for future reference.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 pump switch is not used, the shorting plug must be installed or TASC will not operate. The optional Ground Speed Override switch should be mounted conveniently for the operator's use. This switch can be either hand or foot operated. Check to insure all cables are protected from abrasion and breakage, and secure with cable ties or clamps. C.5.2.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 NOTE: Select the pump with a maximum capacity the next size larger than the calculated capacity required. This will insure that the TASC system will have enough capacity to provide precise control over the expected range of operating conditions. C.6.2. INJECTION PUMP LOCATION Injection pumps must be located as close as possible to the point where the chemicals will be injected into the main boom supply line.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.6.5. PRECISION PERISTALTIC INJECTION PUMP TUBING INSTALLATION Each injection pump comes with two appropriately sized tubes and a bottle of Tube Lube. To install the tubing, remove the retaining hardware from the pump cover and gently pry the cover off, (Do Not Force). Take one of the tubes and coat approximately 12" of its midsection with a liberal portion of the Tube Lube.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 C.7. CHEMICAL CONTAINERS Mid-Tech tanks are ideal containers for handling raw chemicals. Alternative containers can also be used, such as permanently mounted cone bottomed tanks. Whatever chemical container will be used, it is important to select a large enough tank to cover a normal area at the expected application rates. This is particularly true with permanently mounted chemical tanks.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 The Mid-Tech tanks comes complete with a chemical resistant, quick disconnect coupler. The product line between the tanks and the injection pump should be at least 1/8 inch larger than the tubing size in the pump, and it must be fitted with a mating coupler (available through MIDWEST TECHNOLOGIES). It is also recommended that a nearby fresh water source be fitted with a quick disconnect nipple similar to that on the Mid-Tech tank.

98-05010 Rev. - 1 TASC-6000, 6300, 6600 D.0. TASC ROADSIDE/HANDGUN OPERATION TASC roadside spraying operations require a special boom control switchbox or boom interface cable to take advantage of some of the features of the TASC console. Additionally an optional flow switch and cable is needed if a Handgun is to be used. Example 405-0093 Switch Panel D.1 Modes of Operation 'B' Width Normal Ground Speed Override 'C' Width Handgun Off D.1.
98-05010 Rev. - 1 TASC-6000, 6300, 6600 D.2. HANDGUN MODE OPERATION D.2.1. HANDGUN MODE, SET-UP FUNCTIONS To put the TASC in the Handgun mode: A. Set the switches on the Boom Control Switch Panel as follows: Boom Width Switch Mode Switch Ground Speed Override Switch Auto Handgun Off B. Turn the TASC power "ON" and put the mode selector switch to "SET-UP". The following programing functions are available in the TASC console: SPEED: An "Err" message will appear (GSO is not available in the handgun mode).
98-05010 Rev. - 1 TASC-6000, 6300, 6600 D.2.3. HANDGUN MODE, SPECIAL CONSIDERATIONS: A. Pump Calibrations: The speed of the injection pumps during calibration is determined by the programmed test speed ("gallons per minute" or "liters per minute") and the programmed chemical application rate ("ounces per 100 gallons" or liters per 1000 liters") or ratio ("gallons per gallon" or liters per liter). Set these numbers to your typical operating conditions before doing the pump calibrations. B.
