Regulation Parameters
The regulation algorithm is configured 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 3.5
Figure 3-4: Voltage Comparison
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
4 www.teejet.com
854SprayerControl
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.
Figure 3-5: Regulation Stop Band
rE6 1.5
STP BAnd
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.
