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

in error percentage). The maximum value is
10.0%.
• 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 “1.5%”.
• Press the PROGRAM key to accept the value and advance to the next program step.

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.

Display Stabilization
Display Stabilization establishes the stabilization rate that steadies the Application Rate displayed during minor adjustments of the control system. The controller will continue to make the required adjustments at all times. Enter the percentage of allowable change from the target rate in this step.
For example, the system has a target rate of 20 GPA with 5% programmed for Display Stabilization. The display will indicate 20 GPA at any time the actual rate is +/- 5%, or:
• Use the PLUS or MINUS keys to change the value.
• 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 “5%”.
• Press the PROGRAM key to accept the value and advance to the next program step.
NOTE: The Display Stabilization value is limited to
20%. A value of 0% will disable the setting.

Calibrate Tip Level Percent
If both a pressure sensor and a ow meter are installed and being used, the 854 uses one sensor to cross check the other for system errors.
Select the primary sensor (used for regulation) in the Sensor Select step of System Setup Mode. The opposite sensor will automatically perform the cross­checking function.
The Calibrate Tip Level % will establish the % of allowable error between the sensors before an alarm is activated. All sprayer systems have some discrepancy between pressure and ow due to pressure drops and positioning of sensors.
• Use the PLUS or MINUS keys to change the % of allowable error.
• Press the PROGRAM key to accept the value and advance to the next program step.
NOTE: It is recommended that this value remain at
50% unless instructed otherwise.
