System Response
NOTE: Read instructions for complete
detachment.
1. Control must be connected and turned OFF.
2. With electrical harness connected. Move the
POWER switch (top switch) to center or OFF
position (ON, OFF, MOM-ON).
3. Push and hold the POWER switch to the
RIGHT, this sends ground to the ATTACH/
DETACH switch (MOM-ON, OFF, MOM-ON).
By holding this switch to the LEFT, ground
is sent down the YELLOW wire to the plow
module port B. The module then completes
the ground path to the motor relay and
solenoid cartridge valves S2C1 and S4.
4. Hydraulic
fl
uid from the pump
fl
ows through the
activated S2C1 cartridge valve, through CV6 into
the rod end of the lift ram, causing the ram to
retract.
5. The retracting ram pushes hydraulic
fl
uid out
of the base end of the cylinder through the
activated S4 cartridge valve and back into the
reservoir.
6. Retracting the cylinder moves the headgear
forward, dropping the stand. Once the stand
contacts the ground and hydraulic pressure
reaches 550 psi at the rod end of the lift
cylinder, pressure switch (PSW1) will open the
electrical circuit, turning the hydraulic unit OFF.
NOTE: Battery voltage is supplied to the plow module, motor relay, and the 9 solenoid coils when
the snowplow is connected to the vehicle.
