ANGLE RIGHT – ELECTRICAL
System Response
1. By activating the angle right (R on the
control face) 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 S2.
2. Hydraulic fl uid from the pump fl ows through
unactivated S3, through PC1, into the base of
the driver-side ram, causing it to extend.
3. The retracting passenger-side ram pushes the
hydraulic fl uid out of its base end through the
activated S2 cartridge and unactivated S3,
back to the reservoir.
NOTE: Battery voltage is supplied to the Plow
Module, the motor relay, and the three solenoid
coils when the snowplow is connected to the
vehicle.
