Electronic Acremeter
Programming the Acremeter
•If your drill was equipped with this acremeter from production, it will have been supplied already programmed.
•If you ordered your acremeter and install it yourself, it will need to be programmed.
•If your new Great Plains acremeter is not preprogrammed to your drill, see “Acremeter Operations” on page 2 of this manual.
•Find “Calibration For All Drill Models”on page 4.
•FInd “Drill Width Charts” on pages 7 and 8.
•basic hand tools.
a.The electronic acremeter is compatible with all drills having a main or transfer 7/8 hex drive shaft on any section of the drill. The shaft must be before any Drive Type, gearbox, lower, range, transmission or upper variable sprockets, and have only fixed sprockets and chains between the drive wheel and the shaft.

2 Electronic Acremeter
A battery-operated electronic acre counter is supplied with the drill. The display module for the system is normally on the front face of the main toolbar near the left gauge wheel.
The acremeter calculates and displays the field acres and total acres accumulated.
The meter counts rotations of the main ground drive shaft before the clutch. The meter tallies all movements with the drill unfolded, whether planting or not.
The counter operates in one of two modes
•In sleep mode, the display 1 is blank, and the counter is accumulating acres. Sleep mode is entered if a button is not pressed for 20 seconds. If a passcode is set, it must be re-entered to change protected function values.
•In entry mode, the display is on, and the operator can enter values. To access entry mode, press the
button 2 . If you continue to press the button, the acre counter cycles through the available functions. The LED light above the functions indicates which function is selected.
The functions are:
FIELD |
Field Acres |
(always unprotected) |
TOTAL |
Total Acres |
(passcode protectable) |
PULSES |
Pulses per Mile |
(passcode protectable) |
WIDTH |
Swath Width |
(passcode protectable) |
P-WORD Password |
(enable/set/change/clear) |
Note: U = USA units or acres
E = European units or hectares
Values are entered by pressing the UP DOWN 4 arrow buttons. Holding a button automatically increments that value. Long holds increment faster than short holds. Pressing both
buttons simultaneously is used to reset some values to 0.
•To change modes press and hold all 3 switches at the same time. When pressed, the current mode will scroll across the screen. “U” is for USA units, “E” is for European (metric) units. When you have held all
3 switches for 5 seconds the mode will change.
This means you can check the mode at any time by pressing the 3 keys and releasing them before
5 seconds has passed without changing anything.
Note: When you change modes, all the defaults are reset to factory values so these will need to be set properly for the machine. Also area accumulated in one mode is not converted. It is reset to 0.

4 Electronic Acremeter
Pulses per 400 Feet of Travel
Press thebutton until the “PULSES” LED is lit. The number in the display indicates how many pulses are generated for every 400 feet (122 meters in “E” mode) driven.
Note: If a passcode is set, it must be entered to adjust the pulses per 400 feet (122 meters) of travel.
There are two methods to enter the pulses: known pulse value and calibrating pulses per 400 feet (122 meters) of travel.
Known Pulses Values
Refer to Figure 5
1.If you know the number, select it using the UP and DOWN buttons. When you press thebutton, the controller accepts the number in the display as the new pulses per 400 feet (122 meters).
EXAMPLE:
Approximate pulses per 400 feet (122 meters) for 2S-2600, 3S-3000, 3S-4000 and 3S-5000: 17.

Calibrating Pulses per 400 Feet of Travel |
|
|
Note: Calibration is not recommended for the 2S-2600, |
|
|
3S-3000, 3S-4000, or 3S-5000. Any value other |
|
|
than 17 pulses per 400 feet results in reduced |
|
|
accuracy of area measurement. |
|
|
Refer to Figure 6 |
|
|
The acremeter can count pulses, and if the distance |
|
|
driven is known, the pulses per 400 feet of travelb may be |
|
|
entered. Run the test with the drill unfolded, and the |
|
|
openers raised. |
|
|
Pulses Per Mile |
|
|
Note: If you have documentation yet from a past design |
|
|
of acremeter listing the pulse value stated as |
|
|
pulses per mile, divide that value by 13.2 to arrive |
|
|
at a new number. (5280 feet per mile/400 ft = |
|
|
13.2). If you get a fraction round up to the next full |
|
|
digit for the best accuracy. |

Passcode
The “P-WORD” function allows you to protect:
-the total acre count,
-pulses per 400 feet and
-width
settings with a 4-digit passcode. This prevents accidental and malicious changes to those settings. As provided by the factory, the passcode feature is disabled, and you can modify those function values at any time.
Press the button until the “P-WORD” LED is lit. The display reads either:
“Ent” (enter passcode) or “dIS” (passcode disabled)
Enable and Set Passcode
The P-WORD display must show “dIS” in order to enable and set a passcode on a unit which presently has no passcode (see below for changing an existing passcode).
Refer to Figure 8
Use the UP and DOWN buttons to select a passcode in the range 0001 through 9999 (0000 disables).
Press button to accept the passcode. If the module
enters sleep mode before you press the button, the passcode is not set.
Note: The protected function values remain unprotected until the next time the module enters sleep mode.
Using a Passcode
If the P-WORD display shows “Ent”, a passcode must be entered, or the protected function values cannot be changed.
Refer to Figure 9
Enter the passcode using the UP and DOWN buttons.
When your passcode is displayed, press the button to test the passcode.
If the passcode is correct, you can change the protected settings.
The protected settings are unprotected, and the password remains viewable in the P-WORD display function, until the module next enters sleep mode. When button is next pressed, the passcode is again required to change protected settings.
If the entered passcode is not correct, the protected settings cannot be changed. When the “P-WORD” function is selected again, “Ent” appears in the display.

Battery Replacement
The battery operated acre counter uses 3 AA-size alkaline batteries. Although the batteries typically last between 5 and 10 years, they should be inspected annually, as low batteries can leak corrosive chemicals, and damage the electronic acremeter.
If battery replacement is needed, the acre counter displays “LobAt” (low battery).
For battery inspection or replacement, dismount the acre counter from the implement and remove the 4 screws on the back of the case. This will separate the housing from the rear plate. Replace the batteries with 3 high quality AA alkaline batteries.
Note: The module is dust and splash resistant, but under no circumstance should it be submerged in any conductive, corrosive or flammable liquid.
