Raven SCS 460 Installation And Service Manual page 44

8) Verify that each boom valve operates and that no nozzles are plugged by operating the BOOM ON/
OFF switches.
9) Place all BOOM ON/OFF switches to ON.
10) Hold the FLOW CONTROL switch to INC position for approximately 12 seconds. This assures
motorized Control Valve is fully closed. Verify maximum pressure and RATE.
11) Adjust agitator line hand valve for desired agitation.
12) Close the main line hand valve, if necessary, to set the desired maximum operating pressure.
Maximum pressure should be approximately 10 psi [70 kPa] above normal spraying pressure.
EXAMPLE: If normal spraying pressure is 30 psi [210kPa], set maximum pressure at approximately
40 psi [280 kPa].
13) Hold the MAN ADJ switch to DEC position for approximately 12 seconds. This assures motorized
Control Valve is fully open.
14) Close by-pass #1 hand valve to set the desired minimum operating pressure. Minimum pressure
should be approximately one half the normal spraying pressure.
EXAMPLE: If normal spraying pressure is 30 psi [210 kPa], set minimum pressure at approximately
15 psi [105 kPa].
15) Verify maximum and minimum pressures and RATE by repeating Steps 11 and 14.
INITIAL SYSTEM FIELD TEST
1) Drive down field or road at target speed with sprayer booms OFF, to verify SPEED readout on
Console.
2) Turn on sprayer and booms and place the MAN/AUTO switch to AUTO. Increase or decrease
speed by one (1) MPH [2 km/h]. The system should automatically correct to the target application
rate.
3) If for any reason, the system is unable to correct to the desired RATE, check for an empty tank, a
plugged line, a malfunctioning pump, improper vehicle speed or a defect in the system.
4) If the system does not appear to be correcting properly, first review INITIAL SYSTEM SET-UP, then
refer to TROUBLESHOOTING GUIDE.
5) At the end of each row, switch the MASTER ON/OFF to OFF to shut off flow. This also shuts off
the area totalizer.
6) Verify area covered and volume used.
