TITLE
OPERATING GUIDELINES
The purpose of this section is to provide some
general guidelines and recommendations for op-
erating the 8160 in the field.
The console must be configured for the mode
(Spray or NH3) you are going to operate in be-
fore starting the application. Perform both the
Set-up procedure and the Distance Calibration
procedure before attempting to use this console.
Failure to do this will result in faulty control and
inaccurate Volume, Area, and Speed data.
When not applying chemical the console should
be put into the Hold Mode. Move the Run/Hold
switch on the console to the Hold position. This
will shut off the Boom Valves and stop accumu-
lating Volume and Area. This may also be ac-
complished by using a Remote Run/Hold switch.
Using the Remote Run/Hold feature can reduce
the number of operations the operator must per-
form when starting and stopping the applica-
tion.
To apply chemical move the Run/Hold switch to
the Run position as you reach the place in the
field where you want to start the application. It
is best to start moving before activating the Run
Mode and to reach the operating speed as soon
as possible. Return the Run/Hold switch to Hold
at the end of the field. It is best not to slow down
significantly before putting the console into Hold.
This will prevent the Servo Valve from moving to
far from its normal operating position. This re-
duces the time it takes to reach the proper ap-
plication rate as you again start applying.
The Boom switches may be used to shut off
Booms not required such as on end rows. The
console will make the necessary corrections to
insure proper application rates.
The 8160 console will allow you to determine
what is going on with your system. The keyboard
has five keys labeled RATE, ERROR, SPEED,
VOLUME, AREA.
Pressing one of the five keys will display that
selection. The top line of the display will always
show the Target Rate along with either Actual
Rate or % Error as selected by the operator. The
bottom line will display SPEED, VOLUME, or
AREA as selected by the operator. The operator
is free to select whichever selection he desires,
however, the following is a list of recommenda-
tions.
It is important to insure that the 8160 is control-
ling your sprayer properly. The RATE and ER-
ROR keys will show this.
Pressing the RATE key will display the actual
Volume per Area. Pressing the ERROR key will
display the actual error between the Target and
Actual application rates. This is displayed as a
percentage.
The console must be in the Run Mode and be re-
ceiving Speed and Flow signals to display RATE
or % ERROR. Although any calculated errors
less than 10% are considered good The 8160
will control the servo valve until the error falls
below ±1%. The warning light will flash when the
error exceeds ±10%.
The 8160 will automatically adjust the flow
whenever Rate 1 or Rate 2 is selected. Switch-
ing between Rate 1 and Rate 2 can be done at
any time and as often as desired. The 8160 will
change to the new application rate very quickly
and maintain that rate very accurately.
It is highly recommended that the operator take
advantage of the dual rate control. Significant
chemical savings can be made if Rate 2 is pro-
grammed to a higher rate for weedy spots, and
ONLY used when field conditions require it. All
the rest of the time the operator can stay at the
lower Rate 1 and save chemicals.
When required putting the Rate switch in the
center position (Manual) will turn the automatic
control off. Pressure can then be adjusted man-
ually.
