LEFT RETRACT – ELECTRICAL
Blade Movement: Left Retract
Controller Mode: Wing Mode
Controller Button: L/SCP
This button toggles between retract
and extend in wing mode. Upon
entering wing mode, the first
activation of this button and every
other activation thereafter retracts
the wing. The second activation of
this button and every other
activation thereafter extends the
wing.
System Response:
1)
By pressing the controller button,
the circuit board within the cab
control completes the ground path
for the electrical circuit.
2)
Electrical current flows through
the motor relay, activating the
pump motor, and solenoid
cartridge valve S2, shifting its
spool.
3)
Hydraulic oil from the pump flows
through solenoid cartridge valves
S2 & S3, P/O check valve (A),
and into the rod end of the left
cylinder causing it to retract.
4)
Pressure within the hydraulic
circuit causes P/O check valves
(B) & (C) to open.
5)
The retracting left cylinder pushes
the hydraulic oil out of its base
end, through solenoid cartridge
valves S4 & S5, through P/O
check valve (C) and back to the
reservoir.
