CHAPTER 1 SWITCHES AND CONTROLS
everal switches and indicators serve as the interface between the operator and the Mid-
S
Tech control system.
CONSOLE SWITCHES AND INDICATORS
his section shows the location of each switch and indicator found on the TASC 6100 control
T
console and discusses its function in both the
Operate and Setup modes.
POWER SWITCH
The power switch (see #1 in Fig. 1-1) controls power to the console. The CE console has an "Auto Power Down" feature which powers the console off after a operator selectable time has elapsed. The console has a nonvolatile memory so it "remembers" the constants and data previously entered, even with the power removed.
NOTE: The “Auto Power Down Feature is only available on the CE version of the console (CE designation label on back of console).

The Increase/Decrease (INC/DEC) switch (see #3 in
Fig. 1-1) is used, in both the OPERATE and SET-UP
modes, to adjust the values appearing in the display.
BOOM SECTION “ON/OFF” INDICATORS
The boom section On/Off indicators (see #5 in Fig. 1-
1) indicate which boom sections the operator has
selected. When a boom is turned on, its indicator is lit.
There are a maximum of nine boom sections available.
RATE SWITCH
The Rate Selector switch (see #6 in Fig. 1-1) is a three
position switch that allows the operator to select
either a pre-selected standard rate, an alternate rate, or
stop the application.
DISPLAY SELECTOR SWITCH
The Display Selector (see #4, Fig. 1-1) is used to
choose which of the console functions is displayed on
the screen and is available for setting by the operator.

VDC) on the boom interface cable sense line. As long as this condition is present, the control console operates normally. If the voltage is interrupted, the control console automatically stops applying. At the same time, the control console will either "HOLD" or
input must present a positive voltage (+12.0

ech
"CLOSE" the control valve, depending on the response selected by the operator. (See Page 2-7).
This feature allows the operator to control the operation of the control valve through the normal operation of the vehicle. The implement status input can be used to sense the ON/OFF condition of the main vehicle pump switch, a separate Master switch, or, an external switch sensing an implement "UP"/ "DOWN" condition.
GROUND SPEED OVERRIDE SWITCH (GSO)
f your TASC system includes an optional MID­TECH® Boom Control Switch Box, the GSO
I
switch is already installed. An optional, externally mounted, GSO switch can be used to temporarily operate the vehicle using a pre-selected GSO mini­mum speed rather than the actual speed registered by the ground speed sensor. The override feature is used to allow the vehicle to reach the application rate quickly when starting from a complete stop or to maintain a good application pattern when the vehicle is moving at very low ground speeds. It can also be used to allow the operator to flush or empty the tank of a sprayer, or empty the bed of a spreader, from the cab, with the vehicle stopped.
98-05018
R2
Fig. B-8, in Appendix B, shows a “Boom Control Switch Box” which incorpo­rates the Implement Status Switch and the GSO function into one switch. The “OFF” position provides a Status Switch “OFF” condition, “AUTO” furnishes Status Switch ON, and “GSO” activates the GSO function. Other methods of controlling these functions are also available. This switchbox also includes an individual ON/OFF switch for each boom section.
Switches
& Cont.
The control console operates normally as long as the GSO switch condition is open (OFF). Whenever the override switch is closed (ON) and the actual ground speed is
less than the GSO Speed, the control console automatically uses the GSO Speed to control applica­tion rate. As soon as the switch reverts to its normally open (OFF) condition, or the actual ground speed increases above the preset GSO speed, the control console will adjust the rate based on the actual ground speed.
CAUTION: Controlling application rates based on a GSO Speed is not as accurate as using the actual ground speed. When GSO is being used and the true ground speed is less than the GSO speed", the console sounds an alarm and the display flashes a "Too Slow" message to warn the operator of over application.

SETTING BOOM WIDTHS
he MID-TECH control console is designed to automatically compensate for changes in the swath

The display cycles through each boom position (1 through 9) and displays its current width in inches (meters).
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. Repeat for each section.
CE & S
TANDARD V ERSION
C. Set all unused boom sections to a width of zero “0”
inches (meters). This insures that accidentally turning a boom switch ON doesn’t affect the control console. (An ERROR 0 Boom # will then result if an unused boom gets accidentally turned on)

TASC 6100
D. Finally, let the boom width display cycle through the
boom sections until it shows “Boom C”. When the “C” width is displayed, set it to the normal operating width of the entire sprayer, in inches (meters), using the INC./DEC. switch.
E. The boom width is now set. Turn all booms ON and
return to the OPERATE mode. The new total boom width will be displayed in feet (meters). If this does not agree with your total applicator width, check the individual boom widths, ( steps B and C).

DISTANCE CALIBRATION - GROUND SPEED SENSOR
General Considerations and Initial Calibration Numbers
he control console must be calibrated for the ground speed sensor installed to ensure accurate
T
application rates. The procedure involves physi­cally measuring an accurate distance along a road or field, driving the vehicle through that distance, math­ematically comparing the distance computed by the control console to the actual measured distance, and making any necessary adjustments to the distance calibration number. Follow the recommended procedure below to ensure accuracy of operation.
98-05018
R2
Boom widths are entered in inches in the US system. For example; for a liquid boom with 7 nozzles on 30" spacings, enter 210 for that boom. There is no need to convert to feet, the control console does that automatically when it is switched back to the Operate Mode. (In metric, all widths are entered in meters.)
Setup
& Cal.
The distance calibration should be checked periodically to maintain its accuracy. This is especially important if the sensor mounting has become loose or has been repositioned, or if the tires have been changed.
Use the following initial calibration numbers. It is
important to field calibrate the distance sensor to insure maximum accuracy!

Distance Calibration Procedure
The following procedure is recommended by MIDWEST TECHNOLOGIES for establishing an accurate distance calibration. NOTE: All boom switches should remain
OFF during the entire procedure.
A. Fill the vehicle 1/2 full of material (unless it is a pull
type unit with the speed sensor mounted on the tow vehicle), to approximate average load conditions.
B. Measure a known distance of at least 400 ft. in a
field or roadway (preferably in terrain similar to that being treated). A longer distance, allows for a more accurate calibration.
C. Record the current distance cal. #, which can be
viewed using the switch settings shown in the
“G
ENERAL C ONSIDERATIONS AND INITIAL CALIBRATION
NUMBERS” section above. For this example assume
an initial cal. # of 760.
CE & S
TANDARD V ERSION
D. Move the vehicle to the starting point of the
measured distance.
E. Reset the distance accumulator to zero (see page 2-
11)
F. Drive the vehicle to the other end of the measured
distance at a speed of between five and ten miles per hour. Distance will accumulate on the display.
2-6
TASC 6100
G. Stop the vehicle at the measured distance end marker.
Compare the distance indicated by the console to the actual measured distance, to determine how much correction is necessary. For example: if the indicated distance is 396 Ft. after driving over a 400 foot range, the error in the distance calibration is 1.0%.
H. Calculate the new distance calibration number using
the following formula:
Measured distance
Indicated distance
Example:
400
x 760 = 768, the New DC#
396
NOTE: Use the same equation, regardless of the type of
distance sensor .
I. Enter the corrected cal. # using the switch settings
shown in the “GENERAL CONSIDERATIONS AND INITIAL CALIBRATION NUMBERS” section above. Switch back to the OPERATE mode. The distance accumulator should now agree with the measured distance that you traveled. If it doesn't , recheck your calculations.

SETTING THE HOLD/CLOSE RESPONSE OF THE FLOW CONTROL VALVE
he operator can select a "Hold" or "Close" response
of the flow control valve to both “Implement

Status switch” and “All Booms OFF" conditions. These responses are independent of each other, allowing the operator to select a "Hold" condition for one and a "Close" for the other. Careful consideration should be given to both conditions and the response selected for your application.
Implement Status Switch
When the operator selects the "Hold" condition, deactiva­tion of the Implement Status switch (open circuit) hold’s the flow control valve in its current position. When

turning on the Implement Status switch (closed circuit) the flow control valve is already open and product flow is instantaneous. This response assumes that some other device, such as a boom section valve, has stopped the product flow.
When the operator selects the "Close" condition, deactivation of the Implement Status Switch (open circuit) automatically causes the flow control valve to close. This response is preferred when it is necessary to use the flow control valve to stop the product flow.

FLOW SENSOR CALIBRATION
Determining The Initial Calibration Number
The control console must be calibrated for the flow sensor being used. The calibration number required by the control console is the actual number of electrical pulses per unit volume generated by the sensor, or, for the pressure sensor, the gallons per acre rating of the nozzles being used. If you
have any doubts as to the accuracy of the application rate,
2-12
TASC 6100
a field calibration/catch test should be performed. (see page 2-16)
Verify that the correct application program is selected. (see page 2-1)
Check the Correction Factor, to ensure that it is set correctly. (see page 2-11)
FLOWMETER (for Pump L STnrd applications)

Pressure Sensor (U.S. Units)
(for Pump L Psi "US" applications)
The Pressure Sensor calibration number can be found by determining the "Gallons per Acre" rating for the type of nozzles being used. Find the chart that represents the nozzle series you are using and the nozzle spacing of your boom. Then find the nozzle size needed for the

Then, on the left of the chart, find the horizontal line representing the ratings at 30 PSI. Where the column and row intersect you will find the "Gallons per Acre" rating of your nozzles at 10 MPH and 30 PSI. This is the value to enter into the console as the pressure sensor cal. #. For example, in the following chart, for a floodjet K-SS10 nozzle, the row for 30 PSI and column for 10 MPH intersect at 26 gallons per acre, the pressure sensor cal. number for this particular nozzle.
NOTE: You must use the 30 PSI / 10 MPH value regardless of the speed and pressure at which you are operating.

The INC./DEC. switch can now be used to adjust the pressure reading on the console to match the reading on the pressure gauge. If no switch changes are detected for 3 seconds, the console display reverts to "OPEN" again. Actuating the DEC. switch when the console reads "OPEN" causes the console to read "CLOSE" and the valve closes.
Note: A display reading of "PSi (br) - - " indicates that the pressure sensor is not connected. A reading of "PSi (br) ­0" indicates a reading of less than 0 PSI (br). This suggests that the sensor may need to be recalibrated to 0 pressure. (See "Setting The Zero Set Point" on the previous page.)

& Cal.
Once the initial calibration number is determined and entered into the console, a calibration run should be made to adjust the number for maximum accuracy.
The most critical part of the calibration procedure is accurately measuring the discharge of large volumes of liquid. Increased accuracy of measurement means increased calibration accuracy. Since each operator's facilities are different, it is not possible to prescribe a standard method of measuring discharge. Successful methods include using a second, calibrated flow meter, using a truck scale and calculating volumes based on weight and density of the liquid discharged, and by discharging into a calibrated tank.
It will be necessary to pump and measure at least 100 gallons and as much as 300 gallons, depending on the accuracy required. Larger volumes allow greater accu­racy.

A method similar to the following is recommended.
1. If using Pump L Psi, enter the appropriate "Correc­tion Factor" for the material that you will be using for the test (Use factor of 1.00 for Pump L STnrd applications) (see page 2-11).
2. Enter the desired application rate (see page 2-3).
3. Verify that the boom switches are OFF.
4. Verify that the correct initial flow sensor calibration number is entered into the console (See pages 2-12 through 2-14). Use the INC./DEC. switch to adjust as necessary.
5. Reset the Total Applied accumulator to zero (see page 2-11).
6. Make sure there is enough liquid in the main tank to perform the test. Weigh the sprayer and load of water. Position the sprayer in the test area.
7. Start the main carrier pump. Set the Display Selector switch to Test Speed and the Rate Switch to “Standard Rate”. Turn ON the Master switch and the Boom switches. The sprayer starts to spray. Allow the sprayer to run until the desired amount of liquid is discharged. Turn OFF the booms
8. Weigh the sprayer again and calculate the amount of water discharged.
9. View the total amount of dispensed liquid as measured by the console (Total Applied/OPER- ATE). If the total shown on the console agrees with the total amount actually discharged, no further action is necessary. The pressure sensor, or flowmeter, is now calibrated.
10. If the indicated volume pumped does not agree with the actual volume pumped, calculate a new calibration # as follows:

11a. An alternate method, of correcting the cal. #, at
this point, is to switch back and forth, between
OPERATE/Total Applied and SET-UP/ Total Applied, changing the cal. # until the Total Applied display, in operate mode, equals the
amount actually dispensed.
12. Write this number down for future reference. This is the number to use for this specific combination (material and applicator configuration).
Another method of fine tuning the sensor cal. # is to weigh the sprayer with a full tank of water, reset the Total Applied to zero (see page 2-11), set the GSO speed to 10 MPH, and start spraying while watching the Total Applied accumulate. When the Total Applied reaches at least 100 gallons, re-weigh the sprayer and determine the actual amount dispensed as compared to that indicated by the console. Use the method described in step 9 and 10 above to correct the Cal. #.

Changing Application Rate
he TASC 6100 console provides two ways to
change the chemical application rate “on the

ALTERNATE APPLICATION RATE
During the set-up procedure, the operator can set a second application rate into the Alt.-Rate position of the Rate switch (see page 2-3). The operator can now select this rate "on the go" by simply moving the Rate switch to the Alt.-Rate position. The console now controls at the new rate until Standard Rate is again selected. The indicator lamp, above the Rate switch, flashes to remind the operator that a non-standard rate is selected.
CE & STANDARDVERSION
% RATE CHANGE
We will use an example to illustrate the use of this feature.
The operator choses a desired application rate and enters this value into the console using the procedure outlined on page 2-3. Anticipating the need to increase or decrease the application rate, the operator also establishes a % Rate change using the procedure described on page 2-3 of the manual. As an example, assume the console is set up to apply 10.0 gallons per acre with the % Rate change set at 20%
During normal spraying, the control console maintains the application rate at 10.0 gallons per acre. However,

When the Display Selector is turned to any other position, the TASC 6100 reverts to controlling application rate according to the original target rate. The % Rate value remains at the last setting so the operator can reselect it by moving the Display Selector switch back to % Rate. There is an approximate two second delay in valve response after the console has been switched to % Rate to prevent the rates from changing by mistake if the Display Selector is turned through the % Rate position.

Taking time to periodically inspect and clean the wiring harness will help prevent these types of failures.
Inspect the external cabling for abrasion, and stretched or pinched wires. Reroute any damaged cabling and wrap it to protect it from further damage. A broken wire can be temporarily repaired by stripping the wire back on each side of the break, twisting it together, and soldering the connection' (Do not use acid core solder). Insulate the bare connectionwith heat shrink material or electrical tape.
Periodially inspect and clean the connectors at the ends of the cables. Use a non-lubricating spray solvent (such as a tuner cleaner) to clean the connections. If the contact is so dirty it must be wiped clean, use a non abrasive swab (like a Q-

CHAPTER 6 EMERGENCY OPERATION
f the operator is experiencing a failure of the ground speed sensor, the main flow control valve,
I
or the flow or rate sensor, the first step is to carefully check the wiring harnesses for obvious problems and follow the suggested troubleshooting advice outlined in chapter 5.0 of this manual. Assum­ing there is no success in getting the failed component to respond, the following procedures are suggested, as temporary measures, until the component can be repaired or replaced.
The operator, choosing to use one of the following procedures, should realize that application accu­racy is reduced. If this reduced accuracy is accept­able, these procedures will allow operation to continue on a temporary basis.

he control console internally generates a speed signal when operated with the "GROUND
T
SPEED OVERRIDE" (GSO) function activated. When the unit is operated in the GSO mode, the control console establishes the application rate as if the vehicle were actually moving across the field at the programmed GSO speed. This feature can be used to operate the unit, under reduced accuracy, in the event of a failure of the speed sensor.
A. Disconnect the speed sensor cable from the back
of the TASC 6100 console.
B. With the vehicle stopped, condition the console
as follows:
1. All Boom switches (or Master switch)OFF
2. Power ON
3. Mode Selector SET-UP
4. Display Selector SPEED
5. Using the INC./DEC. switch, set the GSO speed for the normal spraying speed, (See Page 3-5 for additional information).

C. Prepare the sprayer
1. Mode Selector switch OPERATE
2. Rate switch Desired position
(Standard Rate/Alt.-Rate)
3. GSO switch ON
4. Drive toward the desired swath, accelerating to normal application speed (as close as possible to the GSO speed value).
D. Start Spraying - As the vehicle reaches the start of
the desired swath, turn booms ON and begin applying.
E. The control console controls the application as if
the vehicle is moving at the established GSO speed. The actual accuracy of application therefore depends upon the ability of the operator to maintain the desired vehicle speed. If the vehicle is traveling at the GSO speed, the application is nearly exact.
F. The console still keeps track of the Total Applied,
and the system still adjusts to changes in boom width. These functions can be monitored on the display.
G. The TASC 6100 display flashes a too slow
message, and an audible alarm sounds, to indicate abnormal operation. There is no speed displayed, areas do not accumulate, and displayed application rate information is meaningless.

FLOW CONTROL VALVE FAILURE
he TASC 6100 system can be operated, at a reduced level of control, 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 flow. Use the following procedure to manually position the flow control valve.

Appendix B SYSTEM OVERVIEW
How The TASC 6100 Controls Application Rate
he TASC 6100 system is designed as a control ler for both liquid and granular application.
T
There are two independent programs in the console, one for liquid and one for granular. The operator can select either program with a simple switch activation. Calibration constants that are set in the granular program stay in memory, even if the corresponding constants are changed in the liquid program. This allows a single console to be moved between a spreader and a sprayer, without requiring complete reprogramming.
The TASC 6100 system senses ground speed, active application width, and product flow rate. A change in ground speed or boom width results in a proportional change of material flow rate to maintain a constant, pre-selected application rate. Comparisons of flow

ach of the five major components are described
below so the operator has a general under
E
standing of how each part performs its job.
1. CONTROL CONSOLE
The TASC 6100 control console is the heart of the system and actually performs three separate functions.
The console contains a small computer with a sophisti­cated control program developed by MIDWEST TECHNOLOGIES. The console continually monitors ground speed and active boom width. As these values change, the console immediately recalculates the required flow rate and makes necessary corrections.
The TASC 6100 console performs the second function of allowing the operator to command the entire system “ON THE GO” from the operator’s seat. The operator has complete control over the application rate which can be altered “on the go”.

Appndx-B
CE & STANDARD V ERSION
98-05018
R2
TASC 6100
The third control console function is to keep the operator informed of the status of the applicator. The control console continually monitors the flow rate, vehicle ground speed and swath width, and immedi­ately warns the operator if the system can no longer maintain accurate application. The warnings are both visual and audible, to attract immediate attention. The large, backlighted liquid crystal display(LCD) gives instant readouts of application rate, volume applied, vehicle ground speed, active boom width, distance traveled, and the area covered while applying.
2. GROUND SPEED SENSOR
The TASC 6100 requires an accurate ground speed sensor. A magnetic pickup wheel sensor, mounted on a non-driven wheel, is very accurate and dependable for most operations.
An optional radar ground speed sensor is available from MID-TECH® for applications where wheel slippage and variations in ground conditions are a concern. The radar sensor does not depend on ground contact and is unaffected by these variables.
Fig. B-3. Ground Speed Radar
CE & S
TANDARD V ERSION
Some applicators may already be equipped with a ground speed sensor. If the sensor meets the accuracy requirements of the TASC 6100 system, it can often be adapted for use with the TASC 6100 Console. Check with your MID-TECH® dealer, or the factory, regarding the use of a specific sensor.
3. APPLICATION RATE SENSOR
LIQUID APPLICATION
Liquid TASC 6100 systems require a flowmeter or pressure sensor in the main boom feed line to measure flow rate and to determine when changes are needed in the position of the flow control valve.
Flowmeter
The flowmeter precisely measures the flow rate of the liquid being discharged. The flowmeter is an impeller device. This means a specific volume of liquid flowing through the flowmeter rotates an impeller a specific
B-4
TASC 6100
number of revolutions. The TASC 6100 System counts the revolutions of the impeller very accurately, allowing the console to calculate the exact flow rate of the liquid in the applicator supply line.
Sometimes an applicator is already equipped with a flowmeter. Existing flowmeters can usually be adapted to work with the TASC 6100 system, as long as the flowmeter measures the total liquid flow to the booms. Check with your MID-TECH® dealer, or the factory, regarding the use of a specific flowmeter. Note: Some flowmeters may require a special adapter cable.
Pressure Sensor
When an TASC system is operating in the pressure based mode, a pressure sensor, rather than a flow meter, is used to determine rate of flow. Knowing the characteristics of the nozzles being used, the console can determine the flow rate of the liquid by monitor­ing the pressure in the boom line.
GRANULAR APPLICATION

R2

AB
When using the TASC console to control a granular application, a rate sensor is necessary to measure the flow of material to the distribution system. Granular rate sensors are usually devices used to measure the rotation of a conveyor feed shaft. Each rotation of the shaft is directly related to the discharge of a specific volume of material.
The most successful rate sensors are usually the slotted disk type, giving 50 to 360 signals per revolution of the shaft. Rate sensors which give only a few signals for each revolution are usually not precise enough for MID-TECH® controllers.
4. FLOW CONTROL VALVE
TASC 6100 systems require a flow control valve to provide automatic rate control. The console uses this valve to control the chemical flow rate. To be effective in controlling flow, this valve must be both fast acting and precise in its movements.

CE & STANDARD V ERSION
98-05018
R2
Fig. B-7. Flow Control Valve
TASC 6100
The flow control valve may be a straight through valve, or a three port Auto-Range® type valve (poly or stainless), controlling the liquid flow directly, or it may be a hydraulic valve, controlling the speed of a hydraulic motor driving the liquid pump or granular conveyor.
Sometimes an applicator is already equipped with an electronically controlled flow control valve. If the valve meets the speed and precision requirements of the TASC 6100 system, it can possibly be adapted for use. Check with your MID-TECH® dealer, or the factory, about the use of a specific valve.
5. BOOM INTERFACE
The TASC 6100 control console must know what boom sections are active at any time, in order to adjust chemical flow rates appropriately. The console can monitor the status of as many as nine separate boom sections. The console can also sense the operation of an Implement Status switch which would result in a selectable response by the flow control valve (position held or full closure). Finally, the system can be equipped with an optional Ground Speed Override switch which, when activated, will cause the control console, under certain conditions, to ignore the actual ground speed and use a pre-selected "Override Speed” to control the application rate.

Glossary
The definitions in this glossary are worded to fit the needs of this manual only and may not apply to all sprayer operations in general.
Auto-Range® Valve - A three port valve which
controls both the main liquid flow and bypass flow.
Boom - An application width that is assigned a value
and is used to calculate area.
Boom Section - A complete boom or part of a boom
that can be turned on or off independent of other boom sections.
Bypass - The process of routing excess product pump
output back to the low pressure side of the pump to control the amount of product available to the spray booms for application. This process is also used in hydraulic flow control also.
CE & S
TANDARD V ERSION
Carrier - A liquid or dry material that is used to
convey herbicide, insecticide, fungicide, micronu­trients, etc., to the ground.
Control Console - An operator console that constantly
monitors all application conditions, such as speed, swath width, and current product flow rate, etc., and sends the necessary control signals to the spray system to maintain the application rate at that designated by the operator.
Electromagnetic Interference - Externally generated
electromagnetic fields, such as those from a high voltage transmission line, a vehicle alternator with a bad diode, sparkplugs, etc., which can disrupt the normal operation of an electronic device.
Flow Control System - A system that includes a
Control Console, a rate sensor device, and a servo control. This system is designed to control product to a target rate.
Flowmeter - A device which measures volumetric
liquid flow. Mid-Tech uses two different basic types of flowmeters.
C-2
TASC 6100
Standard Flowmeters - Each standard flowmeter
has a standard range that it can accurately measure. To change ranges requires changing flowmeters.
Rapid Check Flowmeters - Similar to a standard
flowmeter but has several different “inserts”, each with a different effective range, that can be installed. To change the range of the flowmeter just remove one insert and insert one having the desired flow range.
GSO - Ground Speed Override is a minimum applica-
tion speed. When the vehicle speed drops below GSO, the Control Console controls the output to the GSO speed. Area is accumulated at the actual ground speed.
Hydraulic Servo Control Valve – The term used to
describe a control valve that is capable of receiving and acting upon increase and decrease information from the Control Console and in turn controls the flow of hydraulic fluid.
98-05018
R2
Impeller - A metallic device, similar to a propeller,
used in a flowmeter to monitor the liquid flow. Liquid flowing past the impeller causes it to turn. A magnet sensor, placed near the flowmeter wall, senses the impeller blades as they pass and gener­ates pulses to be sent to the control console.
Implement Status Switch - Provides another means
to stop the spraying operation. This switch may take the form of a foot swich or an implement switch mounted on the toolbar that opens a circuit as the tool bar is raised, effectively stopping the spraying operation..
Liquid Flow Control Valve – The term used to
describe a control valve that is capable of receiving and acting upon increase and decrease information from the Control Console and in turn controls the flow of liquid product.
Master switch - A control switch that allows the
operator to turn on and off all active booms with one switch.

and therefore controlled by the Control Console. This material can be grouped into the following categories:
Liquid – Includes, but is not limited to, liquid
fertilizer, liquid fertilizer with chemical, water, water with chemical, liquid lime, deicing solu­tions, salt solutions, liquid manure, etc.
Chemical – Includes, but is not limited to, herbicide,
liquid fertilizer, spray adjuvants, fungicides, insecticide, etc.
NH3 – (Anhydrous Ammonia) A fertilizer material
that is condensed from a gas to a liquid in order to be metered. Density of this material is entered into the equation in order for pounds of Nitrogen to be targeted and recorded.
