Important Safety Information

Important Safety Information

For your safety and to develop a better understanding of
your equipment, thoroughly read the Operator’s Sections
of this manual before operation.

Safety Notations

The SAFETY ALERT SYMBOL indicates that there is a
potential hazard to personal safety involved and extra
safety precautions must be taken. When you see this sym­bol, be alert and carefully read the message that follows it.
In addition to design and configuration of equipment; haz­ard control and accident prevention are dependent upon
the awareness, concern, prudence and proper training of
personnel involved in the operation, transport, mainte­nance and storage of equipment.

Watch for the following Safety Notations throughout
your Operator’s Manual:

!

DANGER!

Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury. This signal word
is limited to the most extreme situations.

WARNING!

Indicates a potentially hazardous situation which, if not avoid­ed, could result in death or serious injury.

CAUTION!

Indicates a potentially hazardous situation which, if not avoid­ed, may result in minor or moderate injury. It may also be used
to alert against unsafe practices

Safety Rules

These rules and instructions

must be reviewed at least annually

by all operators!

Most accidents are the result of negligence and careless­ness, caused by failure of the operator to follow safety pre­cautions. Even though your implement is designed with
many built-in safety features, the following precautions are
mandatory to prevent such accidents.

Make sure everyone that uses this machine has read the
Operator’s Manual and understands how to operate it
safely.

This Operator’s Manual is considered a part of the imple-

!

ment and should remain so when loaned or sold.

Prior To Operation

1. Do not stand between tractor and implement during hitch­ing.

2. Do not stand between cart and implement during hitching.

3. Do not operate without safety chain properly attached to
tractor.

4. Make sure hydraulic lines are attached to the correct ports.

5. Handle and apply chemically treated seeds according to
manufacturer's recommendations.

CAUTION!

Some illustrations in this manual may show shields or cover
panels removed for clarity. Never operate unit without all
shields and cover panels in place.

During Operation

1. Do not allow anyone to operate this machine who has not

been properly trained in its safe operation.

2. Do not let children operate the implement.

3. Never dismount from a moving tractor

4. Put tractor in park turn off engine and remove key when
making any adjustments to the implement

5. Do not leave the tractor or the implement unattended with
the engine running.

6. Never allow passengers.

7. Travel slowly over rough terrain and be alert to holes and
gullies.

8. Loose fitting clothing should not be worn as it may catch in
moving parts.

9. If a hydraulic leak develops, correct it immediately. Escap­ing hydraulic oil can have extremely high pressure. A
stream of high pressure oil may easily penetrate the skin as
with modern needle-less vaccination equipment - but with
the exception that hydraulic fluid may cause blood poison­ing. It is imperative that the connections are tight and that
all lines and pipes are in good condition. If an injury is
caused by the escaping hydraulic fluid, seea doctor at once!
Use a piece of cardboard or wood to detect leaks of hydrau­lic oil under pressure. Be sure to relieve all hydraulic pres­sure before disconnecting any lines or pipes between the
implement and the tractor hydraulic system.

10. Keep all guards and shields in place.

11. Do not turn tractor too tight; implement may ride up on
wheels causing machine and bodily damage.

DANGER!

Contact with overhead power lines can cause severe electrical
burns or death from electrocution. Make sure there is enough
clearance between all air drill components and overhead power
lines. Do not use loading auger near power lines. Do not climb
on walkboard near power lines.

Section 2 Operating Instructions

Section 2 Operating Instructions

General Description

The seed metering mechanism of this drill is powered by
the cart tire and is driven at a rate proportional to distance
driven. This ensures that the rate applied in pounds per
acre remains constant as ground speed is varied. The
pounds per acre rate is adjustable and can be set using
the gearbox, speed change sprocket and hi-low gears on
the meter. The metering device is driven through an elec­tro-magnetic clutch which will not engage unless the fan
motor is running at high speed and the implement is low­ered past an adjustable height switch. This prevents the
primary seed hoses from being plugged by seed being
metered into them without the fan running and also allows
the seed to be shut off automatically when the drill is lifted
on head lands. The seed bins are sealed and held at the
same pressure as the meter chambers so that metering is
controlled mechanically and not by air flow fluctuations.
The metered seed is carried by air through the primary
hoses to the distribution towers on the implement. These
towers then divide the air and seed into individual rows
and it is carried to the openers in the secondary hoses.

Prestart Checklist

• Lubricate the drill as indicated in the Lubrication portion

of the “Maintenance and Lubrication” section starting
on page 41.

• Check the tires for proper inflation, see the Tire Inflation

Chart in the “Appendix” section starting on page 54.

• Check the chains for proper tension and alignment as

shown in the Lubrication portion of the “Maintenance
and Lubrication” section starting on page 41.

• Perform all beginning of season and daily service items

discussed in the “Maintenance and Lubrication” sec­tion starting on page 41.

• Check the drill for worn or damaged parts and repair or

replace them before going to the field.

• All nuts, bolts and screws should be checked. Refer to

the Torque Value Chart in the “Appendix” section start­ing on page 54.

Attaching the Drill to the Tractor

NOTE: The tractor must be of adequate size to pull
the drill. When determining size of tractor keep in
mind the soil, terrain, row spacing and type of opener.

Recommended Minimum Tractor Size

For standard openers:

34’ Implement - 180 HP
45’ Implement - 240 HP

For double shoot:

34’ Implement - 225 HP
45’ Implement - 300 HP

CAUTION!

The tractor, or towing vehicle, must have adequate unladen
mass to control the drill when towing. Do not exceed 20 miles
per hour.

Minimum vehicle weight - loaded drill:

up to 20 mph maximum - 45,000 lbs.
up to 10 mph maximum - 22,000 lbs.

Minimum vehicle weight - empty drill:

up to 20 mph maximum - 28,000 lbs.
up to 10 mph maximum - 14,000 lbs.

DANGER!

You may be severely injured or killed by being crushed between
the tractor and the drill. Do not stand or place any part of your
body between the tractor and drill while hooking up the drill.

Back the tractor drawbar up to the drill until the holes in the
drill tongue and the tractor drawbar are in line. Use the jack
to make height adjustments. Be sure that the hitch is prop­erly adjusted for level operation, refer to Hitch, Safety Chain,
and Jack in the “Cart Assembly and Setup” section on
page 9. Install the drawbar pin and the pin retainer clip. Re­move the jack and store on the stob on the tongue center rail
in horizontal position. Attach the safety chain on the drill to
an anchor on the tractor capable of pulling the unit.

NOTE: The tractor must have at least 3 sets of hy­draulic outlets and be capable of supplying 15-30 gal­lons per minute at 2000 psi.

WARNING!

Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result.

NOTE: The SAE o-ring and JIC 37˚ flare type hose
connections do not require sealant for reconnecting.
They do not require high torque for a good seal.

IMPORTANT: When using sealant on pipe threads the fric­tion between the threads is reduced; therefore, be certain
not to overtighten or damage to the components may occur.

new quick coupler ends for your hoses.

Make sure that each pair of hoses connected to your trac­tor outlets are from the same circuit (lift, fold, or fan)

Hook up the electric clutch cable to the clutch harness on
the tractor.

If the tractor does not have a clutch harness installed it
must be installed now. Attach the switch box solidly to the
tractor in a convenient location not exposed to rain. Attach
the power leads to a 12 volt D.C. power supply, polarity is
not critical. Be sure that the wire is safely routed where it
will not be pinched or rubbed through. Before drilling any
holes always check on the back side to make sure no hid­den components will be damaged by the drill.

Safety Lights

The light package your drill comes equipped with requires
that your tractor be wired for the standard 7-pin electrical con­nector which will work with the tractor’s flashers and signals.
All that should be necessary is to plug in the connector.

If your tractor is not equipped with this connector please
consult your dealer for installation to tractormanufacturers
specifications.

Rotating auger - To prevent serious injury or death:

•Read all instructions and safety information prior to operation.

•Keep hands, feet, hair, and clothing away from rotating auger.

•Do not remove or modify any guards.

•Keep children well clear of work area.

16. Energize the fold circuit on the tractor. The control le­ver may have to be tied in place.

17. Be sure that nobody is indanger from the auger, then be­fore starting grain flow turn on the auger control valve, re­fer to Figure 2-8. Visually check the auger for correct
direction of rotation. Reverse valve handle if needed.

Great Plains Mfg., Inc.

NOTE: The center location of the valve handle is
“OFF”. Turning the handle to either side will provide
forward or reverse rotation depending on direction of
the flow from the tractor. One side will be forward and
the other will be reverse.

18. Slowly turn on flow of grain and fill bin. Slow down and
then stop flow of grain as level nears the top of the bin
to avoid overflow.

19. Turn off the auger and return to storage position.
Place the front end on the front support first. Push the
auger in until the support arms return to the storage
position. Replace the storage lock pin and clip. Close
the front support latch and replace the pin.

20. Turn off the tractor hydraulics and then return the flow
diverter valve handle to rear (fold) position.

CAUTION!

Do not turn the diverter handle until the hydraulics have been
shut off. If it is moved with hydraulics still on, the implement
wings will suddenly begin folding.

21. Remove any foreign matter from strainer basket.

22. Wipe any grain or foreign matter from lid seal flange
area on top of bin. Close lid and securely latch.

23. Before moving the drill check that the bin lid is latched,
the auger control is off, the flow diverter handle is rear­ward, and the auger is securely latched in transport
storage position.

NOTE: When leveled off, the top cone of the bin holds
approximately 1/3 capacity; the center area
1/3 capacity; and the lower cone 1/3 capacity.

Field Operations

1. Be sure that the cart tires are properly inflated as indi­cated in the Tire Inflation Chart in the “Appendix”
section on page 54.

2. Be sure that all hoses are connected and clear of for­eign material. Make sure openers are not plugged.

3. Never back up with the openers in the ground. Do not
turn sharply with openers in the ground, doing so will
cause openers to plug.

4. Set the seed rate as described in the Setting the Drill
Seeding Rate portion of the “Adjustments” section
on page 20.

5. Turn on the fan hydraulic motor. Be sure the fan ro-

tates correctly.

Great Plains Mfg., Inc.

Section 2 Operating Instructions

NOTE: Fan motor circuit is equipped with a check
valve to allow the fan to wind down freely when shut
off. The bottom of the fan rotor should rotate towards
rear of the cart.

6. Check all bin seals to make sure no air is leaking. Ad­just the latch or replace the seals to prevent leakage.

NOTE: It only takes a very small air leak to cause a
large variation in the seeding rate.

7. Make sure that nobody is in the way of the drill before
moving. Do not allow anybody to ride on the drill.

8. Set the tractor engine idle to an approximate field
speed. Adjust the tractor flow control valve until the fan
pressure gauge reaches approximately 21” of water for
single shoot application (12 ounces per square inch).

9. For double shoot operation adjust the manifold divert­er to provide more air to the meter applying the most
material, see Figure 2-9.

NOTE: Moving the diverter far to one side will severely
restrict air flow to the other bin and may cause plugging.

14915

14922

Single vs Double Shoot Operation

Figure 2-10

NOTE: Always engage the fan motor with the tractor
at a low idle speed. Do not reverse hydraulic flow with
the fan running. Do not exceed 5000 RPM fan speed.

10. Turn on the electric clutch switch in the cab. With the
fan running drive forward and lower the implement to
begin seeding.

NOTE: The electric clutch circuit contains 2 switches
besides the in-cab control. One switch requires that
the fan be running at a suitable speed before seed is
metered to prevent the hose from plugging. The other
switch is on the implement and only turns on the
clutch when the implement is lowered below the ad­justed height. See Electric Clutch Height Switch in
the “Adjustments” section of the Implement manual
for more information. If you wish to run seed through
the system while the drill is stationary you must use
the hand crank as described in Setting the Drill Seed-

ing Rate in the “Adjustments” section on page 20.

Double Shoot Manifold Diverter Control

Figure 2-9

Heavy seeding rates may require a higher setting.
Light rates or very fragile seeds may require a lower
setting for best distribution or if excessive crackage is
evident.

NOTE: To use a double shoot equipped drill in a single
shoot application, such as when placing starter fertilizer
in the furrow with seed, switch the 2 1/2” hoses between
the meters so that the hoses leaving the front meter box
enter the rear meter box. See Figure 2-10. Set the air­flow baffle to provide air only to the front bin. All material
from both bins will now leave the rear meter boxes.

7/28/10

11. Do not shut off the fan motor while seed is being me­tered. Doing so will cause the distribution hoses to
plug. Do not rely on the tractor detent to hold the lever
on. Use a rapidly removable strap or hook to hold the
lever in place.

12. With a properly adjusted implement height switch it is
not necessary to turn the electric clutch switch on and
off manually while turning. The clutch switch should
be turned off while transporting.

13. Be aware of a slight 5‘-10’ delay needed for the seed
to reach the openers when starting. If you stop in the
middle of the field, lift the drill and back up 10‘ then
start from there.

14. Always operate farm machinery with safety in mind.

Setting the Drill Seeding Rate

NOTE: Seeding Rate Charts on the drill and in this
manual are derived from cleaned, untreated seed of
average size and test weight. The rates are based on

23.1 x 26” 12-ply tubeless tires. Many factors will af­fect seeding rate including foreign material, seed
treatment, seed size, and test weight. Minor adjust­ments will likely be needed to compensate for these
factors.

CAUTION!

Obey manufacturer/grower’s reccomendations for safety equip­ment when using treated seeds.

Three settings control the seed rate, they are:

• Metering device driving/driven gear set orientation

• Gearbox settings

• Quick change sprocket orientation

When setting the seed rate make sure that all three set­tings are properly made.

1. Check the seed rate charts, starting onpage 23, or the
seed rate chart located on the bin, for desired settings.
Not all ratios are on the chart on the bin. Consult this
manual for all possible settings.

2. Set driving/driven gears as indicated under the “Gears”
column in the seed rate chart. The driving gear is on the
front or upper shaft. The driven gear is on the rear or low­er shaft. Remove the lynch pins and adjust gear position
as needed, then replace the pins, refer to Figure 3-1.

3. Set the gearbox levers to the required position listed
under the Gearbox Levers column in the Seed Rate
Chart starting on page 25.

IMPORTANT: Always disengage the gearbox clutch han­dle before attempting to shift gears. Failure to do so will re­sult in damage to the gearbox.

Disengage the gearbox clutch handle by releasing
from the catch and pushing in, refer to Figure 3-2.

Disengag

Move shift levers until they are in detents next to appro­priate letter or number. Shift levers should move freely,
refer to Figure 3-3. If levers do not move easily be sure
the clutch handle is pushed in. Use the hand crank to

Section 3 Adjustments

Drive System Adjustment

Chain from Hub to Main Jackshaft

Check the chain slack. Chain should have 1/4” - 3/8” slack
at the midpoint of the span. Adjust the tension as needed
by loosening the bearing support bolts and sliding shaft
forward or rearward, see Figure 3-10.

Check tension on the chain from the jackshaft to the clutch
if any adjustments are made.

Drive Chain from Main Jackshaft to Clutch

1. Make sure both sprockets are aligned. If they are not,
loosen the set screws holding the drive sprocket in
place and move the sprocket over until they are
aligned. Re-tighten the set screws.

2. Check the tension. Rear span of the chain should
have 1/4” slack at the midpoint - do not overtighten, re­fer to Figure 3-11. Loosen bolts holding the clutch
shaft bearings and slide the shaft up or down to ad­just. Tighten bolts. Be sure clutch shaft is kept parallel
with the main jackshaft.

NOTE: The electric clutch anti-rotation tang must be
a loose fit over the stop bolt. If the clutch shaft is
moved to adjust the chain tension be sure to check
the stop bolt. The stop bolt can be moved in its slot to
ensure a loose fit or to get greater chain adjustment
if needed. It is very important that the bolt is not tight
against either end of the slot in the clutch tang to en­sure long clutch life, refer to Figure 3-12

Section 4 Troubleshooting

Problem Solution

Actual seed rate is different from rate
desired.

Erratic seeding pattern or emergence

Air leaks; check for air leaks around lids and on bin. A small air leak can reduce
the seeding rate dramatically.

Gearbox, quick change sprockets or driving/driven gears are not set correctly.
Check the seed rate charts and set them correctly.

Check the cart tires for correct pressure; over or under inflation will affect rates.

Seed treatment building up on meter; unload bin and clean out meter.

Foreign matter is blocking meter. Keep strainer basket in place and foreign matter
out of bin.

Electric clutch height switch is set too low; clutch is not engaging.

Faulty or corroded electric clutch harness connections letting the clutch disen­gage; clean or replace terminals.

Fan speed too low, the pressure switch is not staying set. Run the fan at a higher
speed.

Running meter out of seed. Enough seed should be kept in the drill to cover the
agitator shaft.

Improper clutch sprocket installed; 45’ drills use 29t sprocket; 34’ drills use 38t
sprocket.

Gearbox shifters forced out of place by forcing the gearbox to shift with the clutch
handle engaged. Gearbox no longer indicating actual setting.

Foreign matter in seed. Rate Charts are based on clean, untreated seed.

1” hoses plugged; stop and raise the drill with the fan running. Hand crank the
meter to see if any hoses are plugged, refer to the Setting the Drill Seeding Rate in
the “Adjustments” section starting on page 20.

1” hoses are plugging.

Maintenance

General

Proper servicing and adjustment is the key to the long life
of any farm equipment. With careful and systematic in­spection and lubrication you can avoid many costly repairs
and downtime.

Always turn off tractor and remove the key before making
any adjustments or performing maintenance.

Securely block raised equipment before working under or
around it. Use transport locks on the gauge wheels and
wings.

Read and obey all safety labels on the drill when working
near it.

1. After initially running the drill for several hours, check

all bolts to be sure they are tight. Do not over tighten
the bolts holding the distribution tower assembly to­gether.

2. Lubricate the drill as noted in the Lubrication portion

of this section.

3. Always use equivalent fasteners to replace any dam-

aged or missing bolts.

4. Adjust the idlers to take up excess chain slack. Do not

overtighten.

5. Always maintain correct pressure in the tires.

6. Replace any worn, damaged, or illegible safety labels

at once. New labels can be obtained from your Great
Plains dealer.

7. Any fittings which will nottake grease must be cleaned

or replaced so that lubrication can be performed.

8. Check and repair all air leakage or damage of the Bin

Lid and Meter seals.

Storage

WARNING!

Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be

almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with this type
of injury. Foreign fluids in the tissue must be surgically removed
within a few hours or gangrene will result

Store the drill in an area where children do not play.

1. Release the latch on the bin fill lid to release pressure
on seal.

2. Empty the bincompletely.Turn the meter severalturns
to be sure it is empty. Blow out the meter with air to re­move all material.

3. Raise the auger to filling position then run the motor in
reverse until auger is completely empty. Return to the
storage position.

4. The auger hopper should be turned down to prevent
rain or debris from building up in it.

5. Wash and clean the bin thoroughly inside and out to
prevent corrosion.

6. Open the meter lid doors partially but not enough to let
animals get into meter. Wire doors in place if needed.
Do not store the drill with the seal compressed.

7. If the cart is disconnected from the implement for stor­age plug all 2 1/2” openings to prevent birds from nest­ing in them.

8. Before using the drill check bin bottoms and 2 1/2” out­lets for foreign material. Hand crank drive train to
make sure it is free.

9. Lubricate the drill at all points listed in this section.

10. Remove the drive chains and store them in oil.

11. Check all bolts, pins, fittings, and hoses. Tighten, re­pair or replace parts as needed.

12. Check all moving parts and earth contact parts for
wear or damage. Make notes of any parts needing re­pair before the next season.

13. Use touch up paint to cover scratches, chips, and
worn areas to prevent rust.

14. Store the drill inside if possible to obtain a longer drill
life.

168-233A System Monitor

◗ General Information

The Vansco Electronic Monitor is designed for use with
Great Plains Air Drills.

This monitor is packaged in a black anodized aluminum
housing with a mounting bracket. Cables exit from the rear
of the unit. The front panel contains a five digit, seven seg­ment liquid crystal display, a seven position rotary function
select switch, and three push buttons; ACK/MODE, UP,
and DOWN.

The system is capable of monitoring the following:

• The RPM speed of the fan shaft

• Implement ground speed

• The RPM speed of two meter shafts

• The status of two bin level sensors. Each bin level sen-

Great Plains Mfg., Inc.

sor is associated with one of the meter shafts

• Blockage in up to 120 runs using optional modules and

sensors

• Field and accumulated area that has been worked

Details of operation are provided under the Operating In­structions in this section on page 13.

A continuous audio alarm will sound upon high fan RPM,
low fan RPM, low meter shaft speed, seed run blockage,
or low bin level. While this alarm is sounding the display
will indicate what fault conditions is present. Pressing the
ACK/MODE button briefly will silence the alarm and the
display will revert to its normal display. Every ten seconds
the display will show all fault conditions that are present.
When the fault condition is removed, the alarm message
will be removed also.

The operator has the ability to set certain parameters of
the monitor’s operation. User variable parameters are:

• Low fan alarm point

• High fan alarm point

• Pulses per revolution of fan

• Pulses per mile

• Pulses per revolution of any shaft

• The width of the Implement

• English or metric units

• The number and type of

blockage sensors connected to the unit

The variable parameters, as well as accumulated area are
stored in nonvolatile memory. This means that the infor­mation will be retained even when power is disconnected.

Assembly and Setup

◗ Installing the Monitor Control Box on Tractor

The control box must be installed where it will not be ex­posed to high levels of dust or precipitation.

The mounting bracket can be removed to ease installation.

Attach the black lead to the battery ground and the white
lead to +12 VDC, refer to Figure 7-1. Continuous power is
not required to save monitor settings and the power
source can be turned off when the monitor is not being
used. The unit also has an ON/OFF switch at the rear of
the control box. Route the 12 pin connector lead to the rear
of the tractor so that it can be connected to the cart har­ness. Coil up and secure any excess but be sure to leave
enough slack for turning and uneven terrain.

When all wiring is in place and connected secure the wires
to the drill with cable ties. Be sure that all wires are safe
from moving parts and away from field vegetation. Be sure
all connections are tight.

When installation is complete refer to the following Setting
User Variable Parameters. All operating parameters must
be set before the unit is ready to use.

◗ Setting User Variable Parameters

To view or change any of the user variable parameters,
the Rotary Function Select switch must be set to the de­sired function. The rotary switch is used to select one of
the following seven functions for display.

Switch Position Function

Fan Fan RPM
Speed Ground Speed
Front Shaft Front Meter Shaft RPM
Rear Shaft Rear Meter Shaft RPM
Flow Blockage Module Status
Area / Rate Field Area, Accumulated Area,

or Application Rate Function

Width Implement Width, Units Select

After the Rotary Function Select switch is in position the
ACK/MODE button is pressed and held for five seconds.
While the button is being held, the monitor will give short
beeps, and after the five seconds, the monitor will give a
longer beep. At this time the display will show the param­eter, and allow it to be modified using the UP or DOWN
buttons. Upon entering the parameter changing mode, a
message will be displayed briefly indicating which param­eter is being accessed. This message will be displayed
periodically throughout the parameter changing mode as
a reminder. Pressing the UP or DOWNbuttons will change
the parameter, and pressing the ACK/MODE button again
for five seconds will store the parameter in nonvolatile
memory. The display will then revert to showing the moni­tored function. If the rotary switch position is changed be­fore storing the parameters, the changes won’t be saved.

Setting the Fan Parameters:

When the rotary switch is in the FAN position, pressing the
ACK/MODE button for five seconds will cause the display
to show “PLSE” briefly, and then the number of pulses
that are generated per revolution of the fan. This value is
variable from 0 through 3 using the UP or DOWN buttons.
A setting of zero means that the fan RPM meter is off and
no fan alarm will sound. (“OFF” will be displayed when in
the FAN position.) When the ACK/MODE button is
pressed again, the monitor will display “FAnL” briefly, and
then show the fan’s low speed alarm point. Using the UP
or DOWN buttons, the alarm point may now be changed.
When the ACK/MODE button is pressed again, the display
will show “FAnH” briefly, and then show the fan’s high
speed alarm point. Using the UP of DOWN buttons, the
alarm point may now be changed. Repeatedly pressing
the ACK/MODE button will switch between the pulses per
revolution setting and the alarm points. Pressing the
ACK/MODE button for five seconds will cause the alarm
point and the pulses per revolution to be entered into
memory, and the fan RPM to be displayed.

Refer to the Standard Parameter Settings for the 2250 Air

Drill for Systems Monitor in the “Specifications and Ca-
pacities” section on page 51 for specific values.

Setting Pulses Per Mile:

When the rotary switch is in the SPEED position, pressing
the ACK/MODE button for five seconds will cause the dis­play to show “PLSE” briefly, and then the number of
ground speed pulses required to go one mile (pulses per
mile is also used if in metric units). This value may be
changed using the UP of DOWN buttons.

Alternatively, the pulse rate may be measured. Pressing
UP and DOWN at the same time for five seconds will enter
the monitor into pulse count mode. The display will show
“Cnt” briefly, and then “0000”. The implement should
then be driven over a distance of one mile with the clutch
engaged. While driving, the display will start to count up­ward (this is the number of ground speed pulses received
so far). At the end of one mile, the required pulses will be
shown on the display. Pressing ACK/MODE button for five
seconds will enter the pulse value (regardless of which
setting method was used) into nonvolatile memory.

If the operator tries to save a value below the lower limit or
above the upper limit, the limit value will be saved.

Refer to the Standard Parameter Settings for the 2250 Air

Drill for Systems Monitor in the “Specifications and Ca-
pacities” section on page 51 for specific values.

Setting the Status of Shafts/Bins:

When the rotary switch is in the FRONT SHAFT or REAR
SHAFT position, pressing the ACK/MODE button for five
seconds will cause the display to show “PLSE” briefly,
then display either 0, 1, 2, 3, or 4. The 0 indicates that the
selected shaft/bin combination has been disabled, while
number 1 through 4 indicate the number of pulses gener­ated per revolution of the shaft. The operator may change
the setting using the UP or DOWN buttons. Pressing the
ACK/MODE button for five seconds will enter the status in
nonvolatile memory, and display either the shaft speed or

7/28/10

Model 2250 Air Drill Cart 167-033M

47

Section 6 Options

Great Plains Mfg., Inc.

“OFF”, depending on how the status was set. Setting the

status to 0 (OFF) will disable shaft and bin level monitoring
for the corresponding shaft and bin level sensor (i.e., no
alarms will be generated).

Refer to the Standard Parameter Settings for the 2250 Air

Drill for Systems Monitor in the “Specifications and Ca-
pacities” section on page 51 for specific values.

Setting Blockage Module Complement & Type Value:

When the rotary switch is set to FLOW, pressing the
ACK/MODE button for five seconds will cause the display
to show “tYyy”, where yy indicates the type value. This
number should be set to zero using the DOWN button. Re­peated short presses of the ACK/MODE button will switch
between blockage module complement and type setting.
Pressing the ACK/MODE button for five seconds will enter
these values into non-volatile memory, and the monitor will
return to showing flow information.

If the flow monitoring function is not used, the number of
modules should be set to 0 to prevent alarms from occur­ring. This is the standard monitor setting.

Refer to the Standard Parameter Settings for the 2250 Air

Drill for Systems Monitor in the “Specifications and Ca-
pacities” section on page 51 for specific values.

Selecting English/Metric Units
and Setting the Implement Width:

When the rotary switch is in the WIDTH position, pressing
the ACK/MODE button for five seconds will cause the dis­play to show “Lnth” briefly, then the implement width (sor­ry, but we cannot show “width” on the display). Pressing
the UP and DOWN buttons will cause the width to increase
or decrease. Pressing the ACK/MODE button briefly will
show “unit” then either “Eng” indicating
English Units or “tric” indicating Metric Units). Pressing
the UP button will select English Units, while the DOWN
button will select Metric Units. These units will apply to
ground speed, area accumulation, application, rate calcu­lation, and implement width. Pressing the ACK/MODE
button briefly will return you to the width setting mode,
while pressing the ACK/MODE button for five seconds will
store the selection in nonvolatile memory, and return the
display to showing implement width.

Refer to the Standard Parameter Settings for the 2250 Air

Drill for Systems Monitor in the “Specifications and Ca-
pacities” section on page 51 for specific values.

Operating Instructions

◗ Alarm Systems

Alarms:

Alarms are displayed when the limits described in the
Vansco Electronic Monitor Technical Specifications por­tion of the “Specifications” section, on page 51, are ex­ceeded. When a new alarm condition arises the monitor
will beep continuously and the display will indicate the fault
conditions (this will happen regardless of the position of
the rotary switch).

To acknowledge the alarm the ACK/MODE button must be
pressed. This will silence the audible alarm, and return the
display to showing the monitored function. The display will
now show all fault conditions every ten seconds until the
faults are corrected. If the unit is in a parameter setting
mode, new alarms will have to be acknowledged, but after
being acknowledged, the fault conditions will not be dis­played every ten seconds.

Multiple Alarms:

If more than one alarm condition occurs at the same time,
pushing the ACK/MODE button will acknowledge each
alarm in order of priority. The display will not return to dis­playing the monitored function until all alarms are ac­knowledged.

The order of alarm priority is:

1. High Fan RPM 5. Low Fan RPM

2. Rear Shaft RPM 6. Rear Bin Low

3. Front Shaft RPM 7. Front Bin Low

4. Grain Flow Blockage

Ground Drive Alarm:

Whenever the monitor detects the ground speed going
through 2.0 MPH, a short double beep will be generated.
This will occur if the ground speed is increasing or de­creasing. There is no visual display associated with this
feature. It is only intended to inform the operator that the
clutch is operating properly.

Flow Alarms:

If the error message “Er X” is displayed on the monitor
(where X is a number from 1 through 10), and no blockage
modules are connected, the monitor must be programmed
to disable the flow monitoring function. This is done by set­ting the Blockage Module complement equal to zero as
described under Setting Blockage Module Complement &
Type Value, this page.

◗ Area & Application Rate Modes

Area Rate Modes:

When the rotary switch is set to AREA, the display will
show either “Fxxx.x” or “Axxx” indicating either Field or
Accumulated areas respectively. (When in metric mode
the “F” or the “A” will flash to indicate that metric units are
being used.) Pressing the ACK/MODE key briefly will
switch between the two areas. When showing Field area,
pressing UP and DOWN at the same time for five seconds
will clear the Field area. When showing Accumulated ar­ea, pressing the UP and DOWN buttons for five seconds
will clear both Field and Accumulated areas.

Application Rate Operation:

The application rate mode is used to accurately calculate
the application rate. This is done by operating the imple­ment over an accurately known area and collecting all the
material that would be applied. By dividing the weight of
the material by the area, the application rate is obtained.

To properly collect a sample, with the fan off, cover plate
under each bin meter. Arrange a way to catch the seed

Section 6 Options

and/or fertilizer falling out of the bin meter (sack, bucket,
etc.). Keep the fan off, then pull forward an accurately
known distance. The fan pressure switch must be jum­pered across.

When the rotary switch is set to AREA, pressing the
ACK/MODE button for five seconds will enable the appli­cation rate mode. The display will show “0r00” which is a
measure of the application area precise to 1/100 of an

acre. (If metric units have been selected, the “r” will flash
to indicate hectares.)

Driving the implement will cause the application area to be
incremented, during which time the applied material
should be collected. When a large enough material sam­ple has been collected, the implement should be stopped
the sample weighed. The weight is entered into the moni­tor and the rate is calculated.

Fan RPM

Shaft RPM

Bin Level Indication

Fan RPM is displayed when the selector switch is set to FA N.

The RPM range is 0-9990 RPM with a resolution of 10 RPM.

The fan RPM is continuously monitored for alarm purposes.

The alarm trips when the fan speed falls below the user variable low alarm set point or goes above
the user variable high alarm set point

The factory programmed low alarm point is 3000 RPM. The user adjustable range is between 0 and
the high set point. Low alarm point should be set at 2000 RPM.

The factory programmed high alarm point is 6500 RPM. The user adjustable range is between 0 and
9900 RPM. Reset the high alarm point at 5000 RPM.

The factory programmed pulses per revolution is 1. Reset pulses per revolution to 3.

Response time to an alarm condition is 1 second maximum.

Two shaft speeds, Front and Rear are monitored. Shaft speeds are displayed when the rotary switch is set
to the appropriate position.

The operator may disable unwanted shaft inputs.

The input signal is from a reed switch.

All shaft speeds are continuously monitored for alarm purposes.

An alarm will be generated whenever there is more than 15 seconds between reed switch hits.

Shaft alarm generation will be delayed by 30 seconds if ground speed is below 2 MPH. This delay is
intended to reduce nuisance alarms when turning on headlands.

The monitors are factory programmed with the bins and shafts disabled.

Set both shafts for 2 pulses per revolution.

Two bin levels are monitored; Front and Rear

The bins are pressurized to 20" - 30" H20

The input signal is a Vansco 77000 series optical Type Full Bin Detector

To minimize nuisance alarms, there is a 15 second delay before the bin alarm is displayed

When a shaft input is disabled, the corresponding bin level input is also disabled.

The monitors are factory programmed with bins and shafts disabled.

Ground Speed

Area Meter

Implement Width

Grain Flow Monitor Option

Ground speed in either MPH or KPH is displayed when the selector switch is set to SPEED. (KPH is
obtained by selecting metric units when in width mode.)

Ground speed calibration may be adjusted by changing the pulses per mile setting.

Normal speed is 2.5 MPH to 25 MPH. The display is to one decimal place.

When displaying KPH, the decimal point will flash.

The speed is sensed for a reed switch on the clutch drive shaft.

A short double beep is given when the monitor detects the loss or resumption of the ground speed
signal. Loss of ground speed signal is defined as 2 MPH.

Pulses per mile are variable from 500 to 9999.

The monitors are factory programmed with pulses per miles set to 720. NOTE: When the pulse rate
is set to low values, the accuracy of the area calculations and ground speed will be degraded, and
the rate at which the area and speed is updated will be decreased.

Pulses per mile for a 45’ unit is 2900.

Pulses per mile for a 34’ unit is 2213.

Accumulated or Field areas are displayed when the selector switch is set to AREA. The value displayed is
the area accumulated since the last resetting. In either acres of hectares. (Hectares units are obtained by
selecting metric units when in width mode.

Field Area is displayed on 0.1 acre or 0.1 hectare increments.

Accumulated Area is displayed to the nearest acre or hectare.

When displaying hectares, the decimal point will flash.

The field and accumulated area is stored in nonvolatile memory to a maximum of 999.9 and 9999 acres
respectively. The display then rolls over and begins again from 000.000 (0000). When displaying area in
hectares, the display will roll over at 404.7 (4047) HA, which is the metric conversion of 999.9 (9999) acres.

The operator should note that the area accumulation accuracy depends on a number of variables
such as overlap, turns on the head lands, and unclutching the ground drive. The monitor assumes
there is no overlap when making calculation. If the operator experiences area readings that are per­sistently high, it is suggested that a false implement width be entered. This width would have to be
determined by experience, trial, or calculation.

Implement width is displayed when the selector switch is set to WIDTH.

The factory default setting is 40 feet. The width may be adjusted with the UP and DOWN buttons.
The range is 0 to 100 feet in 0.1 foot steps. (When in metric mode the default setting is 12.1 meters,
and the range is 0 to 30.4 meters in 0.1 meter steps.)

Settings are stored in nonvolatile memory.

Reset width to 45’ (13.7 meters) or 34’ (10.4 meters) depending on unit size.

The unit monitors up to 120 flow sensors using External Blockage Modules. The modules signal the monitor
for loss of flow in any run. Blockage is indicated by module number and run number flashing on the display.
