LEFT (DS) WING EXTEND – ELECTRICAL
System Response
1. Verify that the POWER switch is in the plow
position.
2. By activating the Left Wing Extend 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 S5C2.
3. Hydraulic fl uid from the pump fl ows through
the activated S5C2 through S3 and the pilot
operated check valve PC1 into the base end of
the passenger-side ram, causing it to extend.
4. The extending ram pushes hydraulic fl uid out
of the rod end and back through the activated
S5C2 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.
