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
fluctuations 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 flow beyond the limit.
