EXPLANATION OF SPREADER CIRCUIT
HYDRAULIC
Proportional Valve (SP3) – Spinner ow control valve. SP3 is a proportional solenoid ow control valve.
In its un-energized state it provides a blocked path between the pump ow and the spinner work port. When it is
energized it provides an increasing orice opening to ow as a result of increasing electric current to its solenoid coil.
Proportional Valve (SP2) – Auger/Conveyor ow control valve. SP2 is a proportional solenoid ow control valve. In its
non-energized state it provides a blocked path between the pump ow and the auger/conveyor work port. When it is
energized it provides an increasing orice opening to ow as a result of increasing electric current to its solenoid coil.
Relief Valve (RV3) – Spreader Pressure Relief. RV3 limits the pressure of the spreader motor circuits. It is located in
the pilot load-sense line of the spreader work ports. It ultimately limits the pressure at the RV1 and therefore EV1 which
opens to dump pump ow to tank. RV3 is adjustable. Its pressure setting will be displayed at the LSGP if a spreader
motor load exceeds the relief setting or a blockage of a spreader work port occurs.
CV8 & CV9 – CV8 and CV9 are back-to-back check valves. Their purpose is to communicate the higher of the two
spreader motor pressures of the hoist circuit back to the RV1 boost pressure relief.
CP1 – Auger Reverse Cavity – This cavity can be populated with a solenoid actuated, 2 position / 2 way cartridge to
reverse the auger ow.
