Introduction
INTRODUCTION
ABOUT THE 7000
The 7000 series is a versatile monitoring and control device that is capable of interfacing with many
agricultural systems.
A 4.3” colour touch screen provides a simple but powerful interface for operators as well as providing the
ability to monitor multiple inputs at once.
The display is fully configurable to show any combination of monitored values in both metric and imperial
units. It is also configurable to let the operator control the system outputs by selecting onscreen buttons.
The 7000 series devices have connections for a monitoring camera as well as many different input and
output connections depending on the system configuration. Inputs and outputs to the 7000 series devices
can all be set with alarms to notify the operator if anything goes beyond set low/ high/ proportional
thresholds.
The 7000 terminal can be used in many agricultural applications including but not limited to:

74v1 Spray Controller
74V1 SPRAY CONTROLLER
OVERVIEW
The Farmscan Ag Spray controller 74V1 was developed to provide advanced spray control capabilities
whilst maintaining an extremely simple Tile & Tab user interface.
The controller has a variety of selectable display and control options that can be configured to suit a
specific application or user preference. The controller options and calibration setup can also be locked to
limit operator access.
The optional switch box controller incorporates 5 or 10 section control switches, master on/ off control
and up/ down rate control.
Spray control kits can be supplied with or without pressure relief, flow control valve and 3, 5 or more
section valves.
A large colour LCD touch screen provides all the information required to operate the device in one view
including direct readouts for rate, speed, tank level, trip area, trip volume, time and pressure (optional).
Special icons & widgets indicate active control options.
Spray records are maintained for virtually an unlimited number of paddocks (memory dependent) in the
Jobs screen and may be exported in CSV format via USB to a Windows or Apple-based record keeping
program.
The controller may be operated in automatic, manual or GPS (Slave/ Task) mode - variable rate map (VRC
control via Shape File). In Automatic and Slave mode, the flow control valve responds automatically to
speed and pressure variations or partial section shutdown to maintain the target rate. Manual increment
and decrement of the target rate is also possible.
In Slave/ Task mode, the controller will accept rate commands from a separate guidance/ task computer
linked to GPS and simultaneously report back on rate applied and active sections for the purpose of rate
mapping and verification of sprayed area. Some task controllers also allow for Automatic Boom Switching.
In the event of an error, an audible warning alerts the operator by displaying a red tile (assuming that this
function has been selected on the display) text on a tab which can then be selected to explain the fault.
The 74V1 cab module is connected via CANbus to the flow sensor/ flow control valve and section valves on
the sprayer by our UniPOD to provide section controls, a second spray line or dump valve control.
A standard wheel sensor can be supplied for ground speed pickup or a radar speed sensor may be
connected using the inbuilt radar interface. Alternatively, a GPS can also be used to provide ground speed.

INSTALLATION (SENSORS)
WHEEL SENSOR FOR GROUND SPEED
(Farmscan Ag Part # 1007P Kit)
The wheel sensor consists of a reed-type sensor (magnetic switch) and wheel magnet to be fitted onto any
non-driven ground wheel of the sprayer. The magnet activates the sensor as it sweeps past.
The spray controller requires at least one wheel pulse per second from the sensor.
NOTES:
In circumstances where an extremely large wheel is working at slow speeds (less than 5kph),
additional wheel magnets may be fitted at equal spacing’s.
Any sprayers that do not have a non-driven ground wheel can use a GPS speed sensor as an
alternative.
WHEEL SENSOR INSTALLATION PROCEDURE
To install wheel sensor:
1. Bolt the wheel magnet onto the inside of the wheel in a position that allows the magnet to sweep
directly past the wheel sensor within a 5 - 10 mm clearance. Maximum clearance is 15 mm. The bolt
in the magnet can be replaced with a longer or shorter bolt as required.
2. The magnet can be mounted anywhere in a radius from the centre of the wheel. Nearer to the hub
will ensure the best ground clearance.
3. The sensor must be rigidly bolted to an existing structure, ideally in a protected position to face the
magnet as shown in the diagram below.
4. If the sensor is mounted on a steered wheel, make sure the sensor moves with the steering
mechanism to maintain constant clearance between the magnet and the sensor when turning from
lock to lock.
5. A 5m-extension cable can be purchased to connect the sensor to the sprayer loom connector
marked ‘wheel’. (Farmscan Ag Part # AC-205/5m or AC-210/10m)
6. Use cable ties to secure sensor cable away from risk of damage or chaffing.

Explanation of Components
EXPLANATION OF COMPONENTS
PRESSURE RELIEF VALVE (PRV)
(Farmscan Ag Part # AH-608/G)
The PRV is essential for safe and accurate operation of a positive displacement pump.
The PRV is used to set the maximum pressure available to the flow control valve and
protects the system by relieving excess pressure back to tank when the section controls
are switched off.
NOTE: Failure to use a PRV in a spray system using a positive displacement pump may
result in pump damage.
FLOW CONTROL VALVE
(Farmscan Ag Part # AH-600/G)
The spray controller is designed to operate a DC motorised flow control valve fitted
downstream of the PRV, operating using either proportional or direct flow control to
regulate the main delivery line feeding the flow sensor and section control valves.
FLOW SENSOR
(Farmscan Ag Part # AA-230/A | 10-100L/min)
The flow sensor provides continuous feedback to the spray controller, which
regulates the flow control valve to maintain the required volume of liquid delivered
to the section valves.
NOTES:
All liquid delivered through the flow sensor must go to the section control valves only, i.e. no return
line back to tank or pump can be installed in front of the flow sensor.
The sprayer must operate within the minimum and maximum operating range of the flow sensor,
otherwise erratic and/ or inaccurate control may result.
Check required minimum and maximum flow rate BEFORE installing the equipment.
Alternative flow sensors are available.
Flow rate calculation: Rate (L/Ha) x Speed (km/h) x Width (Metres) = L/Min

Example: 50L/Ha x 12 Kph x 12m = 12L/min
600

Explanation of Components
SECTION VALVES
(Farmscan Ag Part # AH-602/G)
The section valves are controlled by the on-screen widget or smart switch box
switches to provide partial or complete shutdown of the spray boom sections.
3 wire motorised valves: +12V = Red, Black = Negative, Colour = Trigger
2 wire solenoid valves: +12V = Unused, Black = Negative, Colour = Trigger
NOTE: 2 wire motorised section valves require an inline adapter (Farmscan Ag
Part Number # A-2091) to reverse the polarity when switching from ‘on’ to ‘off’.
SECOND SPRAY LINE (OPTIONAL)
A second spray line is activated automatically when the first spray line reaches a pre-set maximum
pressure or speed, thereby allowing greater flexibility in working speeds and additional capacity to change
rates on the go.
The second spray line can be activated at a pre-set speed (equivalent to the first spray line reaching
maximum pressure), when using the optional pressure sensor, the second spray line is activated at a pre-
set pressure or by flow (refer to the maximum litres/min your nozzles can maintain)
Using pressure activation (e.g. 300kpa/43psi) avoids the need to change the set activation point when
changing rates.
When using speed-based activation, the second spray line must be fitted with the same size nozzles as the
first spray line. Choose nozzles suitable to achieve target rates at lower working speeds then allow double
the maximum speed or rate to calculate the full operating range.
When using pressure-based activation, you can choose single step or multi step operating mode:
With single step operation, fit the same size nozzles in both the first and second spray line as above.
With multi step operation, the first spray line is fitted with nozzles one size smaller than the second
spray line. The controller will automatically select first, second or both spray lines to maintain
operation within the desired pressure range.
NOTE: When choosing to use 2nd Line control you must purchase the AC-7410 (10 section harness) to
ensure enough outputs are available. Please contact Farmscan Ag Support to discuss your options.

Explanation of Components
SECOND SPRAY LINE PLUMBING
The second spray line is fitted to the spray boom with nozzles positioned at half centers to the first spray
line (e.g., if using 50cm or 20inch spacing’s for the first line, the second line nozzles should be placed at
25cm or 10inch intervals.) See example diagram below.
The second spray line can be plumbed as a single section covering the entire boom width or alternatively
split into multi sections to match the first spray line sections.
SINGLE SECOND SPRAY LINE (MATRIX MODE)
A single second spray line is adequate in high speed broad acre spraying where section shutdown is
relatively infrequent. The controller will automatically shut down the second spray line if one or more of
the first spray line section valves are switched off.
A single second spray line requires one large section valve to activate the second spray line.
All the second spray line nozzles must be inter-connected on one independent hose with multiple infeed
points to equalise pressure over the whole width.
The second spray line section valve must tee off the main delivery line after the flow sensor and flow
control valve.
3 wire motorised valves: Red = +12V Black = Negative Colour = Trigger

19
Explanation of Components
SPLIT SECOND SPRAY LINE (INDIVIDUAL MODE)
A split second spray line is necessary when sections are frequently shutdown during operation.
A split second spray line requires a separate section valve for each section of the second spray line.
Each second line section valve must feed the matching width as covered by each first spray line section
valve.
The first and second spray line section valves should be plumbed onto a common manifold and must tee
off the main delivery line after the flow sensor and flow control valve.
