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.

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.)

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

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

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.
