POWER
Power On the Console
To power on the console:
1. Press and release the PROGRAMME button.
The console will initially display the software version at the top of
the screen and the serial number of the console at the bottom of the
screen. After approximately 3 seconds, the console will enter the
work screen.
Power O the Console
To power off the console:
1. While pressing and holding the MINUS button, press and
release the PROGRAMME button.
2. Release the MINUS button.
The console will save new information (area and volume counters)
to memory before it powers down. Pressing any key during the
power off count down will cancel the shut off function.
Automatic Shutdown
With the Master Switch in the “OFF” position, the console will
automatically shut down after 10 minutes of no inputs (or at the time
specied in the Automatic Shutdown Time setting in the OEM Setup
Mode).
APPLICATION MODE
The 845-AB gives the possibility of working in two different ways
to t the application. Therefore, the console should be set up and
consequent programming and working features will be dependant
of the chosen mode.
Airblast Mode
This mode is designed to work with Airblast sprayers, mostly
spraying on two sides (left and right) with the possibility to switch
on or off sections in the height. The working width is dened by
the distance between two rows of trees. This mode is called AB
(airblast).

Working Width
High Clearance / Vineyard Mode
This mode is designed to work with vineyard sprayers that are
spraying horizontally. Several rows are covered and sections can
be switched on or off to adapt the working width. Each section
covers a number of faces. The working width is dened by the
number of faces and the row width.
One or more nozzles can be spraying each face. If all nozzles
spraying on a face are not equal, they should be considered
as a unique nozzle and the total ow has to be set up in the
conguration menu. But all faces have to be sprayed equally. This
mode is called HC (high clearance / vineyard).

Step Display Description Default
AB Mode – The ow rate for each section of the sprayer
must be input into the 845-AB console so that the necessary
adjustments can be made when boom sections are shut off. The
console is programmed to treat the left and right boom sections
as symmetrical; therefore the console treats the ow rate for
the lower left section (L1) identically to the ow rate of the lower
right section (R1). The ow rate entered for section 1 will serve
as reference ow for L1 and/or R1.
HC Mode – The ow rate for a single nozzle must be input
into the 845-AB console so that the necessary adjustments
can be made when boom sections are shut off. If several
different nozzles are mounted to spray on a face, they should
be considered as ONE nozzle and the total ow should be
programmed.
NOTE: In AB mode, the reference flow is the total flow at
reference pressure of all nozzles on the given section
number on one side of the sprayer. The console is
programmed to treat the left and right boom sections as
symmetrical. Therefore, the console treats the flow rate
for the lower left section (L1) identically to the flow rate
of the lower right section (R1). The flow rate entered
for section 1 will serve as reference flow for L1 and/
or R1. The flow rate entered for section 2 will serve as
reference flow for L2 and R2 and so on.
In HC mode there is only one setting per preset. The
reference flow in this case represents the flow for one
single nozzle at the reference pressure. If several
different nozzles are mounted to spray on each face,
they should be considered as ONE nozzle and the total
flow should be programmed. All faces on the sprayer
must have the same nozzle configuration.

SWATH WIDTH
The 844-AB can be programmed with up to 6 swath widths. This
allows the operator to easily change from one swath to another
during application. (This is essential when spraying orchards that
have varying swath widths.)
To enter swath width presets mode, press and hold the GREEN
button for 3 seconds. The swath width setting screen for preset
number 1 will be displayed. The swath width is displayed on the
lower right of the console (measured in metres for SI [metric] units).

Use the Plus and Minus keys to adjust the value for the rst
swath preset. Press the GREEN button or the Programme key
to advance to the next swath preset. Use the Plus and Minus
keys to adjust the swath value. Continue this process through the six
possible presets. If all six presets are not required, enter values only
for the necessary number of presets. All others should be set to “0”.
Values set to “0” will not be available for selection. Once the presets
have been entered, press the GREEN button or the Programme
key to return to the Operations mode.

Manual/Automatic
Regulation Mode
In manual mode, automatic rate regulation is stopped completely.
XPressing the PLUS button simply moves the regulating valve to increase the ow (or increase the
PWM duty cycle) as long as the button is pressed.
XPressing the MINUS button gives the opposite action.
The valve (or the PWM duty cycle) stays in the position it had when the PLUS or
MINUS button was released. The application rate value shown on the screen is the actual rate for the
given speed. Since automatic regulation is stopped, it will appear that the rate value changes when the
speed is changed.
