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 / SETUP” SWITCH
The Mode Selector switch (upper right center) is used to switch between the OPERATE and SETUP modes of the control console. When applying materials, this switch must be in the “OPERATE” position. The “SET- UP” position is used for entering information into the console. In the SETUP Mode an “Err” message will appear if a position which can not be programmed has been selected.

1.3. INC / DEC SWITCH

The INC/DEC switch (upper right corner) is used to change the values appearing in the display. The INC/DEC switch is usable in either the OPERATE or SETUP Mode.
This switch is also used to zero the accumulated areas, distance, and total applied by selecting the desired display and holding this switch in the “DEC” position until the display resets to zero, (approximately 3 sec.).
Use this switch to reset the full load condition while displaying Product Vol. in the operate mode. Holding the switch in the "INC" position until the display shows the programmed, full load value.

SPEED: The current vehicle speed in tenths of a Mile per Hour.
FIELD AREA: Accumulated Area, in hundredths of an Acre.*
TOTAL AREA: Accumulated Area, in Acres.*
PRODUCT V OL.: Amount of product aboard the vehicle. Resets to a pre-programmed, full load by holding the INC
switch up with ground speed zero. Ground speed zero also allows setting any value using the INC/DEC switch. Value counts down as the product is applied, an alarm sounds with ten percent left aboard.**
% RATE: The percent of programmed application rate at which the product is being applied. This percentage can be
changed up or down a preset amount by operating the INC/DEC switch.***
APPLICATION RATE: The desired application rate can be set with the INC/DEC switch when the ground speed is zero
or all booms are OFF.** Once application has commenced, and metered discharge is established, the actual measured application rate will be displayed here. Also used to set the controlvalve to manual operation.
TOTAL APPLIED: The actual volume applied, as measured by the flowmeter or pressure sensor.*
IMPL. WIDTH: The active boom width in tenths of Feet. Depends on the actual boom sections selected “ON”.
DISTANCE: The accumulated distance in Feet, Miles after 5,280 Ft.*
PRIME: This position is used to lock the control valve open during main pump priming on a liquid system. Initially the
display will show a series of five dashes. Hold INC switch up for three seconds to lock the control valve fully open. The display will read OPEN. Switching away from PRIME will cause the control valve to drive CLOSED. When operating in the pressure based (Psi) mode, the current boom pressure is displayed here.
TEST SPEED: The speed the console will use for stationary tests of the sprayer. Use the INC/DEC switch to change this
value.**
SCAN: The display will scan SPEED, FIELD AREA, PRODUCT VOLUME, APPLICATION RATE, TOTAL APPLIED,
and, if in pressure based mode, BOOM PRESSURE. The display will hold at each position for approximately two seconds before automatically cycling to the next.
NOTES: * Totals can be zeroed in this mode.

1.5. BOOM SECTION “ON/OFF” INDICATORS
The boom section on/off indicators (lower right, labeled “BOOMS”), indicate which boom sections have been selected by the operator. When a boom has been selected, its indicator will light. Boom position number 1 is to the left. There is a maximum of nine boom sections available.

1.6. NOT USED

1.7.--STATUS SWITCH

A status switch can be used to override the ARC control. The switch must present a positive voltage (+12.0 VDC) status on the green (or white) wire of the Boom Interface Cable. So long as this condition is present, the control console will operate normally. If the voltage is interrupted, the control console will automatically stop controlling. At the same time, the control console will either "HOLD" or "CLOSE" the control valve, depending on the response selected by the operator. (See Section
2.9.1).
The intent of this feature is to allow the operator to control the operation of the control valve through the normal operation of the vehicle. The Status switch input may be used to sense the "ON"/"OFF" condition of the main vehicle pump switch, a separate Status switch, or, an external switch may sense an implement "UP"/"DOWN" condition. The Status switch can often be used to lessen the operator's work load.

1.8. GROUND SPEED OVERRIDE (GSO) SWITCH

If the ARC system was purchased with an optional MID-TECH boom switch box, the Ground Speed Override switch is already installed. If a MID-TECH switch box is not used to control the booms, an optional externally mounted Ground Speed Override switch can be used to temporarily operate the sprayer (or spreader) using a pre-selected Minimum "(GSO) Speed" rather than the actual speed registered by the Ground Speed Sensor. The override feature is used to bring the applicator on line quickly when starting from a dead stop or to maintain an adequate application pattern when the vehicle is maneuvering at very low ground speeds. It can also be used to allow the operator to flush or empty the vehicle from the cab, while stopped.
The control console operates normally so long as the Ground Speed Override switch condition is open (OFF). Whenever the Override switch is closed (ON) and the actual ground speed is less than "GSO Speed", the control console automatically selects the "GSO Speed" value 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 on the basis of the actual ground speed.
CAUTION: Controlling application rates based on "GSO Speed" is not as accurate as using the actual ground speed. When Ground Speed Override is being used and the true ground speed is less than the "GSO Speed", the console will sound a warning beep and the display will flash a "Too Slow" message to warn the operator of over application.

2.0. CALIBRATION AND SET UP

NOTE: PLEASE READ THROUGH THE FOLLOWING SECTIONS COMPLETELY BEFORE YOU BEGIN CALIBRATION!
The control console needs to be calibrated and programmed with certain information before it is ready to be used. First, the console needs to be programmed with the specific details of your applicator (i.e. Application Rates, Boom Widths, Test Speed, etc.). Next, the rate sensor (flowmeter) and ground speed sensors both need to be calibrated. The calibration and set up processes are not difficult, however; they must be followed precisely in order to get the maximum available accuracy out of the system.
First, BE SURE THE CONSOLE IS SELECTED TO THE APPLICATION PROGRAM YOU WANT. The Choices are; Liquid Pressure, Liquid standard, Liquid reflow, Granular standard, and Granular split drive.

2.1. CHANGING THE APPLICATION PROGRAM

To view the program currently selected, set the Mode switch to "SETUP" and the Display Selector to "PRIME".
Pump L PSi is LIQUID PRESSURE application (normal pressure based spraying) Pump L STnrd is STANDARD LIQUID application (normal flow based spraying) Pump L rEFLO is LIQUID REFLOW application (for use on some European sprayers) Pump C STnrd is standard GRANULAR application (single conveyor spreaders) Pump C SPLit is GRANULAR SPLIT DRIVE application (dual conveyor spreaders, air delivery spreaders)
98-0501
Rev.- 1
To change programs, hold the INC switch up to set LIQUID and cycle between standard, reflow, and pressure. Hold the DEC switch down to set GRANULAR and cycle between standard and split drive. The application remaining in the display when the INC/DEC switch is released is the program selected.

When operating as a LIQUID applicator the control console is capable of displaying three separate units of measure, English, Metric and Metrish. Metrish is the same as Metric, except area is measured in Acres, thus the term Metrish. Operating as a
granular applicator, the display is limited to English units of measurement.

2.2.2. CHANGING UNITS (LIQUID APPLICATOR ONLY)

To change units, set the Mode switch to “OPERATE” and the Display Selector to “SPEED”. The current speed units will be displayed. Holding the INC/DEC switch up or down (see chart) until the display changes (approximately 5 sec.) will set the units accordingly.
UNITS INC./DEC. Switch
English to Metric DOWN Metric to English DOWN English to Metrish UP Metrish to English DOWN
NOTE: Metric to Metrish is not allowed. Convert to English first and then to Metrish.

2.3. SETTING APPLICATION RATE

The ARC system is designed to maintain a constant, pre-selected application rate. In order for the control console to do this, the operator must enter the desired application rate.
A. Set the console switches to the following positions:
Power ON Mode Selector OPERATE (Application rate is set in the Operate Mode!!!) Display Selector APPLICATION RATE Ground Speed ZERO All Booms OFF
The display will show the current application rate.
B. Use the INC/DEC switch to set the value displayed to the desired rate.
C. Setting the APPLICATION RATE to 0.0 will shut off the flow control function.

2.4. SETTING THE % RATE CHANGE

This feature allows the operator to change the application rate “On The Go”. Application rate is changed with a simple actuation of the INC/DEC switch. The amount of change each switch actuation makes is proportional to the value pro­grammed into this position, (e.g. 20 =20% change in the target rate). For example, if the liquid application rate is set at 10.0 gallons per acre, a single actuation of the INC switch will cause the valve to control flow at the rate of 12.0 gallons per acre (10.0 + 20% = 12.0).
A. Set the console switches to the following positions:
Power ON Mode Selector SETUP Display Selector % RATE
The display will show the current % change value.
B. Use the INC/DEC switch to set this number to the desired % change value.

2.5. SETTING BOOM WIDTHS

The MIDWEST TECHNOLOGIES control console is designed to automatically compensate for changes in the swath width, caused by turning on or off boom sections. For the console to automatically respond to changes in swath width, it needs to know the size of each boom section. Use the following procedure to set boom section widths.
CE & STANDARD VERSION

ARC 6000
A. Set the console to the following positions;
Power ON Mode Selector SET- UP Display Selector IMPL. WIDTH All Boom Solenoid Switches (external) OFF
The display will cycle through each boom position (1 through 9) and display its current width in inches.
B. As each boom position appears on the display, use the INC/DEC switch to set the display to the number of inches
covered by that boom. Repeat for each section.
NOTE: Individual boom widths are entered in inches. For example; for a liquid boom with 7 nozzles on
30" spacings, enter 180 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.
C. Set all unused boom sections to a width of zero “0” inches. This will insure that an accidental boom switch ON will not
affect the control console.
D. The boom width is now set. Turn all boom switches to the ON position and return to the OPERATE Mode, the new
total boom width will be displayed in feet. If this does not agree with your total applicator width, check the individual boom widths, (steps B and C).

2.6. APPLICATION RATE SENSOR CALIBRATION

The control console must be calibrated for the flowmeter, pressure sensor, or rate 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 flow sensor
readings, a field calibration/catch test should be performed using the actual product solution. (see section 2.6.1.4)

2.6.1. CALIBRATING THE LIQUID APPLICATION

Verify that the correct application program has been selected (see section 2.1.)!
If in the Psi mode, check the correction factor. It should be set to 1.0 during the calibration routine. To check the correction factor, set the Display Selector to APPLICATION RATE, set the Mode Selector switch to SETUP. Use the INC/DEC switch to set the correction factor if necessary.

2.6.1.1. DETERMINING THE FLOWMETER INITIAL CALIBRATION NUMBER

FLOWMETERS are calibrated for water at the factory. This number is accurate enough for most applications. However, the
actual flow characteristics may differ due to plumbing or other factors.

Once the initial calibration number has been entered into the console, proceed to section 2.6.1.4 to fine tune the flowmeter for maximum accuracy.

2.6.1.2. DETERMINING THE PRESSURE SENSOR INITIAL CALIBRATION NUMBER

The Pressure Sensor Calibration Number can be found by determining the "Gallons per Acre" rating for the type of nozzles being used. First find the chart that represents the nozzle series you will use and the nozzle spacing of your boom. Then find the nozzle size needed for the range of speeds and the rate needed. When the nozzle has been selected find the column of nozzle ratings in "Gallons per Acre" at 10 MPH. 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 cross at 26.0 gallons per acre, the pressure sensor cal. number for this particular nozzle.
NOTE: We recommend that these tests be done using water, and only after neutralizing the tank and system.

Use the following procedure to enter the flow sensor calibration number.
A. Set the console to the following positions;
Power ON Mode Selector SET- UP Master Switch OFF Display Selector TOTAL APPLIED
B. Use the INC/DEC switch to select the desired flow sensor calibration number.

2.6.1.3. PRESSURE SENSOR HIGH/LOW CALIBRATION

The pressure sensor's low and high values must be set to match the readings from your pressure gauge following the proce­dure below.
SETTING THE LOW SIDE:
A. Set the console to the following positions;
Power Switch ON Setup/Operate Switch OPERATE Display Selector Switch PRIME Master Switch ON At least one Boom Switch ON (to release any trapped pressure)
(May have to remove nozzle if it has a check valve)
Ground speed 0 (zero) GSO Switch OFF

B. Hold INC/DEC switch to DEC until console reads PSi 0
Note: A display reading of "PSi - -" indicates that the pressure sensor is not connected. A reading of "PSi - 0" indi­cates a reading of less than 0 PSI. This suggests that the sensor may need to be recalibrated to 0 pressure.
SETTING THE HIGH SIDE:
A. Set the console to the following positions;
Power Switch ON Setup/Operate Switch OPERATE Display Selector Switch PRIME Master Switch ON Supply Pump ON Ground speed 0 (zero)
B. Hold the INC/DEC switch to INC for about 3 seconds. The display will read "OPEN". Release the INC switch. Push
the INC switch again and hold it for about 3 seconds. The display will read "PSi xxx". The xxx is a pressure. 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 after 3 seconds, the console will read "OPEN" again. Actuating the DEC switch when the console reads "OPEN" will cause the console to read "CLOSE" and the valve will close.

2.6.1.4. FINE TUNING THE FLOW SENSOR CALIBRATION NUMBER

98-0501
Rev.- 1
NOTE: We recommend that these tests be done using water, and only after neutralizing the tank and system.
Once the initial calibration number has been determined and entered into the console, a calibration run should be made to adjust the number for maximum accuracy. The hardest part of the calibration procedure will be accurately measuring the actual discharge of large volumes of liquid. The more accurately the discharge is measured, the more accurate the calibration will be. Since each operator's facilities are different, it is not possible to prescribe a standard method of measuring discharge. Operators have successfully performed the task 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 marked, calibrated tank.
It is necessary to pump and measure at least 100 gallons, and as much as 300 gallons, depending on the accuracy required. For example: if the actual measurement is accurate to within 3 gallons, using 300 gallons will yield an accuracy of 1 %.
If only 100 gallons are pumped and measured, the calibration can be off as much as 3%. The better the measurement accuracy of actual discharge and the more material pumped, the more accurate will be the resulting calibration.
A method similar to the following is recommended.
1. If using Psi mode, enter the appropriate Correction Factor for the material that you will be using for the test (Not applicable for rEFLO or STnrd applications) (see section 2.4.1).
2. Turn the Mode Switch to "OPERATE", the Display Selector to "APPLICATION RATE". Enter the desired application rate.
3. Verify that the boom switches are "OFF", select the "SETUP" mode; rotate the display selector switch to "TOTAL APPLIED".
4. For Psi mode applications, the current pressure sensor calibration number will be displayed. Verify that it is the recommended initial calibration number for the nozzles installed in the system. For rEFLO or STnrd applications, the flowmeter calibration number will be displayed (rEFLO mode requires all booms be on to view cal. #.) Use the INC/DEC switch to adjust as necessary.
5. Select "OPERATE" with the mode selector switch. Hold the DEC switch down for three to five seconds to zero the accumulated gallons.
6. Make sure there is enough liquid in the main tank to do the test. Weigh the sprayer and load of water. Position the sprayer in an appropriate area to do the calibration test.
