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
DS ram, causing it to extend.
3. The retracting PS 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.
