1.2 Master Switch Module
The master switch has three positions OFF, AUTO, and MANUAL. AUTO position is where the system is
controlling based on actual ground speed and the current application rate. MANUAL is a momentary
position that allows the system to control at a preprogrammed manual ground speed. The manual ground
speed value can be changed under the setup menu.
The controller can be locked into MANUAL by holding the master switch in the MANUAL position and
pressing the RIGHT arrow key. The MANUAL position forces the controller to use the manual ground speed,
which minimizes system lags when starting up from slow speeds. To exit this condition and return to AUTO
mode, the master switch must be turned OFF then back to AUTO.
Important: If the Land Manager® SE system is replacing a CCS 100 system, the CCS switch module must
be replaced with the new master switch that was shipped with the Land Manager® SE system.
1.3 Ground Speed Sensor
This sensor will constantly communicate the current ground speed back to the Land Manager® SE. Based
on the ground speed the Land Manager® SE will calculate and adjust the output accordingly.
1.4 Feedback Sensor
This sensor communicates back to the Land Manager® SE the amount of product that is being dispersed.
IE. Pressure sensor, Flowmeter, or Application rate sensor.
1.5 Control Valve
This is the metering device for the material that is to be controlled by the Land Manager® SE. The control
valve can be of many types. I.E. Servo, Proportional, Air, etc.
1.6 Harnesses
The harnessing consists of two harnesses. The J1 harness, which is the main implement harness and J2,
which is the power and boom sense harness.
2 Console Interface
The Land Manager® SE console has three mode keys. These three keys separate the functionality of the
unit into Operate, Setup and System menus. See the mode diagrams in Appendix A for screen layout.
2.1 Operate Mode
This is the mode where application occurs. The operate mode has multiple screens that can be viewed by
pressing the operate button.

Air, and Proportional.
DRIVE FREQUENCY The range is 40 to 250 Hz.
NOTE: The anhydrous configuration will not have a choice for drive type or frequency. The anhydrous
configuration is only for DICKEY-john servo valves. Be sure to read and observe the following safety
precautions before proceeding.
Basic Rules When Handling Anhydrous Ammonia
Important: Be sure to read and observe the following safety precautions before proceeding.
Anhydrous ammonia can cause severe injury if improperly handled. (See sidebar on next page). Any person
engaged in handling ammonia can reduce risk of serious accidents by observing a few basic rules:
1. A fail safe valve (hydraulic or electric) is required to provide shutdown capability in the event of an
electrical failure.
2. Know the product, its characteristics and behavior.
3. Use only equipment suitable for anhydrous ammonia service, and make sure it is properly installed
never try to just get by.
4. Make regular inspections of equipment to ensure everything is fully maintained. Always perform
corrective measures immediately to maintain a high level of safety.
5. Use and maintain standard protective equipment necessary to safely handle anhydrous ammonia.
6. Obtain proper training in handling and application of anhydrous ammonia.

1511001-1248-200306
7. Store and handle anhydrous ammonia in accordance with state and local regulations. Where no state or
local regulations exist, use only equipment that is constructed in accordance with The Fertilizer Institute
Standards.
8. Ensure all ammonia is out of the system before disconnecting or disassembling any parts. Be alert for
frosting which is a certain indication of trapped liquid ammonia vaporizing. Depressurize all hoses when
not in use. Lack of frost does not always indicate a lack of ammonia.
9. Always repair ammonia leaks immediately.
10. Inspect hoses thoroughly before each season or when the hose has been subjected to abnormal abuse.
Ensure hoses are not kinked. Check for breaks or softening in the cover, blistering, swelling, loose
couplings or damage to the hose reinforcement. Correct any defects or retire the hose from service.
Replace hoses as recommended by the manufacturer.
Important Notice:
Physiological Responses to Ammonia Vapor
Concentrations for ammonia in air is measured by parts per million (ppm) and 10,000 ppm = 1%. Exposure
levels tolerated by average persons can produce severe respiratory damage to others. First aid for all
ammonia victims consists of fresh air and plenty of water for affected areas. Competent medical assistance
must be obtained immediately for anyone who has been burned or overcome by ammonia.
The average persons response when exposed to different concentration levels of ammonia vapor are -
• 5 ppm - Least perceptible odor.
• 20-50 ppm – Readily detectable odor.
• 50-100 ppm – No discomfort or impairment of health for prolonged exposure.
• 150-200 ppm – General discomfort and eye tearing; no lasting effect on short exposure.
• 400-700 ppm – Severe irritation of eyes, ears, nose, throat; no lasting effect on short exposure.
• 1,700 ppm - Coughing, bronchial spasms.
• 2,000-3,000 ppm -Dangerous, less than 1/2 hour exposure may be fatal.
• 5,000-10,000 ppm - Serious edema, strangulation, asphyxia, rapidly fatal.
• 10,000 ppm - Immediately fatal.
11. Always pick up a hose by the valve body or coupling, never by the valve handwheel.
12. Always stay clear of valve or hose openings, particularly safety relief valves. This is true even when
you believe you have depressurized the system.
13. Use only proper capacity safety relief and excess flow valves. Do not tamper with them or other safety
devices.
14. Never use wrenches in closing handwheel operated valves.
15. Always stand on the upwind side of ammonia transfer operations.

1611001-1248-200306
16. Be certain to wear tight fitting safety goggles or a fullface shield and protective gloves made of rubber
or other material impervious to anhydrous ammonia when transferring ammonia.
17. Be certain no person or animal is in line with the discharge before opening any ammonia valve into the
air.
18. Close all valves and disconnect all hoses when transfer operations are suspended or unattended.
19. Install an automatic liquid relief (Hydrostatic) valve in any location where a possibility of liquid
anhydrous ammonia could be trapped. This valve must open at a safe pressure and discharge into a
safe location.
20. Be sure there is a proper shutoff valve on both sides of any point where a disconnect is made.
21. Do not assume that all ammonia is out of the system just because the relief valves have been opened
and there is zero pressure. Ammonia can remain in the system for several days and sometimes even
weeks depending upon weather conditions.
22. Clean, service and replace safety breakaway valves in accordance with the manufacturer’s instructions.
23. Be aware that ammonia can collect in low parts.
WARNING: The Land Manager® SE is warranted and guaranteed with only Dj recommended
peripheral devices (i.e. Radar ground speed sensor, valve actuators, flowmeter, etc.). Other

2.4 Application Calibration and Fine Tuning
This section will describe the calibration of flowmeters, nozzles, and spreader constants. The ground speed
and auto gain calibrations have been covered in previous sections and need to be done prior to this section
to ensure accuracy.
2.4.1 Nozzle Calibration
In order to do a nozzle calibration the manual ground speed needs to be set at the maximum application
speed along with the correct application rate. Add water to the tank and locate the sprayer where stationary
water will not cause any damage. Start the vehicle and set the engine RPM to normal operating speed that
will be used in the application. Place the master switch into MANUAL position and press the RIGHT arrow
key. This will lock the unit into manual ground speed. Allow time for the air to purge out of the lines and
verify that all of the nozzles are spraying correctly. Verify that the control is stable and proceed with the
calibration. The nozzle calibration can be done 3 ways.

1811001-1248-200306
Nozzle Calibration Device
Measure and record the output of all of the nozzles along with the nozzle pressure. Average all of the
nozzles and use that number as the NOZZLE CONSTANT. Then enter the pressure used while calibrating
as the NOZZLE PRESSURE.
Catch Test Using a Calibrated Container
The second method of nozzle calibration is to catch the water in a calibrated container. Collect the output
from each nozzle for one minute. Record the fluid ounces per nozzle. Convert the fluid ounces to gallons
by dividing by 128 or convert ounces to milliliters by multiplying by 29.57. Average the output of the
nozzles and enter that value for the NOZZLE CONSTANT and enter the pressure while calibrating as the
NOZZLE PRESSURE.
Catch Test Using Scales
The third method of nozzle calibration is to catch the water and weigh it. Weigh the empty container and
record that weight. Collect the water from one nozzle for one minute. Take the pounds of water in one
minute and divide by 8.34. For metric, one Kg of water equals one liter. Repeat this on all of the nozzles.
Average the output of all the nozzles and enter that value as the NOZZLE CONSTANT and enter the
pressure while calibrating as the NOZZLE PRESSURE.
Fine Tuning the Calibration
If the actual application is 5% above the TARGET APPLICATION rate the NOZZLE CONSTANT needs to
be increased by 5%. Therefore if the NOZZLE CONSTANT is 0.5 a 5% increase would be 0.5*1.05 and the
new NOZZLE CONSTANT is 0.525. The opposite applies for under application.
2.4.2 Liquid Flowmeter Calibration
Every flowmeter has a K-factor which represents the pulses per unit of measure. The K-factor may be
marked on the housing or labeled somewhere on the assembly. Some flowmeters have K-factors that are in
imperial liters. The conversions of imperial liters to gallons is 1 liter equals 0.2641721 gallons. This K-
factor is a good starting point before doing a flowmeter calibration. In order to do a flowmeter calibration
the manual ground speed needs to be set at the maximum application speed, along with the correct
application rate. Add water to the tank and locate the sprayer where stationary water will not cause any
damage. Start the vehicle and set the engine RPM to normal operating speed that will be used in the
application. Place the master switch into MANUAL position and press the RIGHT arrow key. This will lock
the unit into manual ground speed. Allow time for the air to purge out of the lines and verify that all of the
nozzles are spraying correctly. Verify that the control is stable and proceed with the calibration. The
calibration can be done 3 ways.
Nozzle Calibration Device
Measure and record the output of all of the nozzles. Add up the output of all of the nozzles and take that
times 5. Clear the accumulators and run the system for 5 minutes with the master switch in manual mode
then turn the controller off. Compare the accumulated value to the calculated value that was previously
made. Determine the percent of error and adjust the K-factor accordingly.
Catch Test Using a Calibrated Container
The second method of flowmeter calibration is to catch the water in a calibrated container. Collect the
output from each nozzle for one minute. Record the fluid ounces per nozzle. Convert the fluid ounces to
gallons by dividing by 128 or convert ounces to milliliters by multiplying by 29.57. Add the output of the
nozzles and take that times 5. Clear the accumulators and run the system for 5 minutes with the master
switch in manual mode, then turn the controller off. Compare the accumulated value to the calculated value
that was previously made. Determine the percent of error and adjust the K-factor accordingly.
Catch Test Using Scales
The third method of nozzle calibration is to catch the water and weigh it. Weigh the empty container and
record that weight. Collect the water from one nozzle for one minute. Take the pounds of water in one
minute and divide by 8.34. For metric, one Kg of water equals one liter. Repeat this on all of the nozzles.
Add the output of all the nozzles and take that times 5. Clear the accumulators and run the system for 5
minutes with the master switch in manual mode, then turn the controller off. Compare the accumulated

1911001-1248-200306
value to the calculated value that was previously made. Determine the percent of error and adjust the K-
factor accordingly.
Fine Tuning the Calibration
If the actual application is 5% above the TARGET APPLICATION rate the K-FACTOR needs to be
decreased by 5%. Therefore if the K-FACTOR is 1500 a 5% decrease would be 1500*0.95 and the new K-
FACTOR is 1425. The opposite applies for under application.
2.4.3 Spreader Constant Calibration
The manufacturer of the spreader will have a SDF (Spreader Discharge Factor). The SDF can be used to
calculate the spreader constant as follows: Spreader Constant = 360/SDF. Therefore if the SDF is 0.18 then
the spreader constant is 360/0.18 which is 2000. If the system is replacing a CCS 100 / CMS 100 system
the old spreader constant can be converted over. To convert a CCS spreader constant to a Land Manager®
SE spreader constant the calculation is as follows: CCS spreader constant * 1728. If the CCS spreader
constant was 0.5787 then the new SPREADER CONSTANT is 0.5787 * 1728 which is 999.99.
Fine Tuning the Calibration
If the actual application is 5% above the TARGET APPLICATION rate the SPREADER CONSTANT needs
to be decreased by 5%. Therefore if the SPREADER CONSTANT is 1500 a 5% decrease would be
1500*0.95 and the new SPREADER CONSTANT is 1425. The opposite applies for under application.
2.4.4 Anhydrous Flowmeter Calibration
Every flowmeter has a K-factor, which represents the pulses per unit of measure. The K-factor may be
marked on the housing or labeled somewhere on the assembly. This k-factor is a good starting point before
doing a flowmeter calibration. In order to do an anhydrous flowmeter calibration the system must be ran in
the field. With the K-factor entered and accumulators cleared, record the weight of the nurse tank and
proceed to apply anhydrous on at least ten acres at normal operating speeds and conditions. Verify that the
control is stable during the calibration. Once the area is covered, record the tank weight. Calculate the
amount of anhydrous used and compare that to the controllers accumulated values. Determine the percent
of error and adjust the K-factor accordingly. A typical DICKEY-john anhydrous flowmeter K-factor starting
point is 2.15 P/In3.
Fine Tuning the Calibration
If the actual application is 5% above the TARGET APPLICATION rate the K-FACTOR needs to be
decreased by 5%. Therefore if the K-FACTOR is 2.250 a 5% decrease would be 2.250*0.95 and the new K-
FACTOR is 2.1375. The opposite applies for under application.
