DISPLAY
During Calibration the display allows you to see
and adjust all calibration numbers. Upon comple-
tion of Calibration, the controller displays the “ini-
tializing Servo Valve” message and sets the valve
to a starting position that depends on the “Inline” or
“Bypass” location of the Servo Valve.
During normal operation any two of the ten func-
tion keys may be displayed. Pressing one of the
ten keys, % ERROR, RATE, VPM, TOTAL AREA,
TOTAL VOL, SPEED, DISTANCE, FIELD AREA,
FIELD VOL or DATE/TIME will display that select-
ed function on the bottom line of the display. The
previous bottom line function will now be shifted to
the top line of the display.
The following is a list of display messages and
their meanings.
HOLD
Reminds the operator that the 8605 is not automat-
ically controlling the sprayer, that all boom valves
are closed and the distance, acre and gallon coun-
ters have stopped accumulating. Hold is only dis-
played in Rate or % Error.
ERR
This stands for percent of error. The percent differ-
ence between the rate selected (RATE 1, RATE 2
or VARIABLE) and the rate being measured by the
combination of speed and flow signals. If the Rate
Selector Switch is in the Manual Position, MAN.
ERR will be displayed.
LOW BATTERY POWER
This is a warning that the battery power supplied
to the 8605 is less than 10 VDC. This condition
causes the 8605 to suspend operation. The 8605
will remain in this mode until battery power is 10
VDC or more.
NO-SPD
This is a warning that the speed signal is missing
or that the speed is too slow for the 8605 to oper-
ate in the RATE 1, RATE 2 or VARIABLE RATE
modes. Either increase your speed or switch to
manual operation. No-SPD is only displayed in
Rate or % Error.
ZERO WIDTH ENTERED
This is a warning that the Booms have zero en-
tered for implement width. Enter the correct width
values.
NO-FLO
This is a warning that the flow signal is missing or that
the flow is too low for the 8605 to operate in the Rate
1, Rate 2 or variable rate modes. Either increase flow
by increasing speed or application rate or switch to
manual operation. No-flo is only displayed in Rate or
% Error.
TOT VOL
This is your total accumulated volume. This is mea-
sured as gallons or pounds of actual Nitrogen.
TOT AREA
This is your total accumulated area counter and is
measured in acres.
FLD AREA
This is the accumulated area for the current field, and
chemical number. It is measured in acres.
FLD VOL
This is the accumulated volume for the current field
number and chemical number. It is measured in gal-
lons or pounds of actual Nitrogen.
SPEED
Displayed as “MPH” (Miles per hour).
DIST
This is your accumulated distance traveled in feet.
RATE (GPA or PPA)
This is your actual application rate measured in gal-
lons per acre or actual pounds of Nitrogen per acre.
The left side of the display shows the TARGET RATE
and the right side shows the ACTUAL RATE.
MIN
Indicates Minimum flow to the booms caused by the
servo valve at the end. Displayed only during Rate or
% Error.
MAX
Indicates Maximum flow to the booms caused by the
servo valve at the end. Displayed only during Rate or
% Error.
LIM
Lim stands for limit. LIM is flashed on the display if
the Minimum Flow Rate feature has been enabled
and the actual flow rate falls to the value set. It is only
displayed if RATE or % ERROR has been selected.
