SCOOP – ELECTRICAL
System Response
1. By activating the SCOOP
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 valves S4,
S7, S8 & S11, activating these
valves.
2. Hydraulic fluid from the pump
flows through activated S4 & S7
then into the base end of the
driver-side angle ram, forcing the
rod to extend.
3. Hydraulic fluid from the pump also
flows through activated S8 & S11
then into the base end of the
extending PS ram.
4. Hydraulic fluid exiting the rod end
of the angle rams flows through
S7 to the base end of the
DS ram, and through activated
S11 to the base end of the PS
ram. This fluid mixes with the
fluid from the pump.
NOTE: This is called a regenerative
hydraulic circuit. Even though
both sides of the ram piston will
experience the same hydraulic
pressure, the ram will extend due
to unequal force. The difference in
area between the base end and
rod end of the ram piston creates
a greater force on the base end
which extends the ram.
Force = Pressure X Surface Area.
NOTE: Battery voltage is supplied
to the Plow Module, the motor
relay and the 11 solenoid coils
when the snowplow is connected
to the vehicle.
