Regulation Parameters
The regulation algorithm is congured with the next three parameters:
1. Minimum Regulating Valve Voltage: the minimum voltage that can drive the regulating valve.
2. Regulation Stop Band: the maximum allowed application error rate.
3. Rotation Time of Regulating Valve: the total time required to close the regulating valve at maximum speed.
These three OEM parameters depend on the regulating valve used.
Minimum Regulating Valve Voltage
The console uses variable voltages to drive the regulating valve. Select the minimum voltage that the regulating valve needs to make it turn at its slowest rotation speed (i.e., if the motor of the regulating valve turns with a minimum of 3.5v, the number should be used in this location).
The affect of this parameter on the regulation behavior is illustrated in Figure 2-4. This value must match the actual operation of the regulating valve used. Check with the valve manufacturer for the value.
• Use the Plus or MINUS keys to change the voltage.
• Press and hold the AUTO/MAN key for 3 seconds to set the value to “0.0”.
• Press the AUTO/MAN key once to set to the default value of 3.5v.
• Press the PROGRAM key to accept the value and advance to the next program step.
NOTE: Standard TeeJet Technologies regulating
valve minimum voltage is 3.5v.
If 12v is selected as a minimum voltage, no variable voltage regulation occurs. Instead, a pulse regulation occurs. This is necessary when using solenoid operated regulating valves (i.e., a Ramsay valve).
Figure 3-3: Minimum Regulating Valve Voltage
rE6
Figure 3-4: Voltage Comparison
3.5
Regulation Stop Band
The Regulation Stop Band is the maximum error percentage allowed on the application rate before the regulating valve reacts (i.e., if a stop band of
1.5% is selected, there is no action on the regulating valve if the actual application rate is within 1.5% of the target rate). This minimum percentage prevents the regulating valve from oscillating in a narrow band around the target point.
• Use the PLUS or MINUS keys to change the regulation stop band (value is expressed

Rotation Time of Regulating Valve
The Rotation Time of Regulating Valve is the number of seconds the regulating valve needs to turn from the complete closed position to the complete open position at the nominal voltage (i.e., 14v).
Use the PLUS or MINUS keys to change the rotating time of the regulating valve in seconds (minimum “0’s”, maximum “50’s”).
Press and hold the AUTO/MAN key for 3 seconds to set the value to “0.0”.
Press the AUTO/MAN key once to set the value to the default setting of “6 seconds”.
Press the PROGRAM key to accept the value and advance to the next program step.
NOTE: Standard TeeJet regulating valve rotation
time is 6 seconds.
The console uses this parameter to control the regulation speed. The value must match the actual operation of the regulating valve used. Check with the valve manufacturer for this value.

Section Valve Type
The Section Valve Type distinguishes the type of On/ Off boom control valves installed on the machine. There are 2 types of valves that can be used:
• 2-way valves
• 3-way valves
A 2-way control valve is simply an On/Off valve. Flow is either directed to the boom section(s) or it is blocked.
A 3-way control valve is known as a Bypass valve. Flow continuously passes through this valve. When the valve is activated (on), ow is directed to the boom section(s). When the valve is not activated (off), ow is directed through a bypass port back to the supply tank.
• Change the value if required by pressing the PLUS or MINUS keys.

CHAPTER 5 - OPERATIONS
Sprayer Evaluation
Before spraying, check all connections related to the Sprayer Control System. Particular attention should be given to the sensors to ensure the console received strong, uninterrupted signals. Make sure connections are made and the sensors are working properly.
IMPORTANT! When working around a sprayer or
chemicals, always wear protective clothing and eye wear.
NOTE: It is recommended that the entire sprayer
be calibrated to prepare the machine for operation and to diagnose spray tip wear. Worn tips can contribute to costly chemical waste and inaccurate spraying, regardless of the use of a sprayer control. Calibration is necessary to obtain the benefits associated with a computerized sprayer control.
Partially ll the sprayer tank with water to ush the system. Perform a visual inspection of the spray tips to ensure all tips are delivering a good spray pattern.
• Set the Master Boom Switch to the “Off” position.
• Make sure the tank shutoff valve is open.
• Start the vehicle’s engine, engage the pump, and set the RPM to that being used when spraying.
• Turn the 854 on by pressing the PROGRAM key.
• Ensure that the preset reference ow arrow matches the set of tips being used.
• Verify that the 854 recognizes the simulated speed. If the simulated speed has been
854 Sprayer Control
disabled (due to vehicle movement) activate the simulated speed by turning the Master Boom Switch “On” and pressing the PROGRAM and MINUS keys simultaneously for a Low simulated speed, or by pressing the PROGRAM and PLUS keys simultaneously for a High simulated speed.
• Turn each individual spray boom section “On”.

• Press the AUTO/MAN key so that the red LED indicates “MAN” mode.
• Toggle the Master Boom Switch to the “On” position.
• Adjust the pressure with the PLUS or MINUS keys. The pressure should increase when the PLUS key is pressed and decrease when the MINUS is pressed.
Check the sprayer to ensure it is activated. Visually ensure spray tip performance.
• Press the AUTO/MAN key so that the red LED indicates “AUTO” mode. The control console should regulate to the target application rate for the simulated speed.
• While spraying, press the PROGRAM and PLUS keys simultaneously for a High simulated speed. The 854 should increase

pressure and regulate to the target application rate for the high simulated speed.
• While spraying, press the PROGRAM and MINUS keys simultaneously for a Low simulated speed. The 854 should decrease the pressure and regulate to the target application rate for low simulated speed.
To stop spraying, toggle the Master Boom Switch to the “Off” position.
Spraying
Fill the sprayer tank and mix the solution thoroughly. Determine the application rate as well as the nozzles being used. All data is programmed into the 854 console.
• Power up the 854 by pressing the PROGRAM key.
• Toggle the individual boom switches to the “On” position for each of the booms on the sprayer.
• Press the AUTO/MAN key so that the red LED indicates “AUTO” mode.
• In Auto Mode, with the Master Switch set to the “Off” position, the console will display the target application rate and a target symbol. When the Master Switch is set to the “On” position, the actual rate will be displayed and the target symbol is no longer visible.
• During application, with the Master Switch set to the “On” position, the display will always indicate the actual application rate, vehicle speed, application area covered/total volume applied, and pressure (only if a pressure transducer has been installed).
• When the location to begin spraying has been reached, turn the Master Boom Switch to the “On” position. The spraying operation is now active. Maintain the usual vehicle speed for spraying. Moderate changes in vehicle speed
do not affect application rate. Moderate speed uctuations are compensated for by automatic pressure increases or decreases by the 854.
If it is necessary to stop during application, turn the Master Boom Switch to the “Off” position.
Alarm warnings can occur momentarily while the pressure regulating valve is searching for a new setting (i.e., after the close of a boom section or other change in normal operation). However, if the alarm stays on for a longer period, the valve may have reached its limit and the system is unable to regulate ow beyond the limit.

Area/Volume Display
WARNING! Clearing the area/volume counter
as indicated blow does not save the information. If the information is to be saved for future reference, refer to the Memory Feature of this User Guide.
With the Master Boom Switch in the “On” position, the 854 Sprayer Control counts application area and measures the total volume applied.
The area counter measures treated acres and is dependent on the values programmed for the number of tips per boom section and the tip spacing.
The volume measure is dependent on ow meter pulses, if a ow meter is present. If not, it is calculated based on pressure signals from the Pressure Transducer.
Depending on console programming during OEM Setup Mode, the lower right of the console will display:
• volume sprayed
• area covered
• both (alternating every three seconds)
To clear the area counter/volume measure:
• Set the Master Boom Switch to the “Off” position.
• Press and hold the AUTO/MAN key for three seconds.
• The controller will display a message asking if the eld counter should be cleared.
• Use the PLUS or MINUS keys to select either “YES” or “NO”.
• Press the PROGRAM key to accept the change and return to normal operating mode.
