LEFT (DS) WING RETRACT – ELECTRICAL
System Response
1. Verify that the POWER switch is in the plow
position.
2. By activating the Left Wing Retract function on
the cab control, the control sends a signal to
the plow module to complete the ground path
for the electrical circuit, activating the motor
relay and solenoid cartridge valve S5C1.
3. Pressure within the hydraulic circuit causes the
PC1 pilot operated check valve to open.
4. Hydraulic fl uid from the pump fl ows through
the activated S5C1 into the rod end of the
driver-side ram, causing it to retract, hydraulic
fl uid fl ows through the open pilot operated
check valve PC1 and back through the
activated S5C1 to the reservoir.
NOTE: Battery voltage is supplied to the
plow module, motor relay and the 9 solenoid
coils when the snowplow is connected to the
vehicle.
