Explanation of Components
PRESSURE SENSOR (OPTIONAL)
(Farmscan Ag Part #: AA-114 Pressure Sensor | 0 - 600kpa/85psi)
The pressure sensor measures spray line pressure at the section manifold to provide a pressure readout
and to control the slow hold and second spray line functions (if used).
Using a mechanical pressure gauge fitted to the spray boom as a reference, the pressure sensor reading
can be adjusted to compensate for line loss between the control bank and the spray boom.
DUMP VALVE (OPTIONAL)
(Farmscan Ag Part # AH-602/G)
The dump valve opens automatically whenever the sprayer stops or when all
section valves are switched off. This option reduces reliance on the pressure
relief valve to greatly reduce back pressure on a positive displacement pump.
NOTE:
The dump valve should be installed before the flow control valve. (Refer
page 13 for example)
CONNECTIONS
(Farmscan Ag Part # AC-7405 “5 Section” or AC-7410 “10 Section”)
A CANbus loom connects the 74V1 to the UniPOD. The UniPOD connects to the controlled elements (flow
control valve, section valves, dump valve etc.)
Connect the labelled connectors on the loom to their respective sensors (flow, wheel and pressure) or
equipment (section valves and control valve).
NOTE:
Only connect power after all other installation steps are complete.
