Theory of Operation
1. The Sno-Way Snow Plow Control System includes a
hand held controller. When a switch is actuated, the
controller sends a signal out to the snow plow through the
plow control harness indicating which operation is to be
performed, such as ’Raise’, ’Swing Right’ and ’DP On’.
2. The second key part of the Control System is the
receiver on the plow. It receives the signal from the hand
held controller and processes the signal to open or close
the proper electrical switches to turn solenoids and
valves on or off so that the hydraulic system of the plow
power unit will perform the required operations.
3. 12V DC power is fed into the receiver from the battery
terminal of the start solenoid. 12V DC power is then fed
out of the receiver to the start solenoid primary circuit
and to the coils of the valve solenoids. The ground wires
for the start solenoid primary circuit and the coils of the
valve solenoids return to the circuit board of the receiver
where switches on the circuit board open or close the
ground to complete or break the circuit to each coil and
solenoid.
4. A low voltage power circuit leads from the receiver to
the hand held controller. This powers the circuit board of
the hand held controller and supplies the low voltage
power needed to process the signal from the switches on
the hand held unit and send a signal back to the receiver
on the plow.
Controller Operation
Functions - Handheld Straight Blade
The hand held controller contains all of the control
functions necessary for the operation of your Sno-Way
snow plow.
The curved rocker switch in the center of the touchpad
controls the ’Raise’ and ’Lower’ functions. Pressing the
forward portion of the rocker switch will ’Raise’ the plow.
Pressing the rearward portion of the rocker switch will
’Lower’ the plow.
Pressing the raised switch on the right side of the
touchpad will swing the blade to the right. Pressing the
raised switch on the left side of the touchpad will swing the
blade to the left.
The round button in the lower center is the ’Down
Pressure’ switch. Pressing the button will turn on the
down pressure, and a red indicator light in the center of
the switch will glow. Pressing the button again will turn the
down pressure off. The round button in the lower right is
the ’On-Off’ switch. A green indicator light in the center of
the button will glow when the controller is ’On’.
The round button in the lower left has no function at this
time, and was designed into the controller for possible
future use.
Functions - Joystick Straight Blade
The joystick controller contains all of the control functions
necessary for the operation of your Sno-Way snowplow.
The joystick on the top of the controller controls the
’Raise’, ’Lower’, and ’Angle’ functions. Pulling the joystick
toward you will ’Raise’ the plow. Pushing the joystick
away from you will ’Lower’ the plow. Moving the joystick to
the right will swing the blade to the right. Moving the
joystick to the left will swing the blade to the left.
There are two buttons on the front of the controller. The
button on the right is the ’Down Pressure’ button. Pressing
the down pressure button will turn on the down pressure,
and a red indicator on the top right corner of the controller
will glow. Pressing the button again will turn the down
pressure off.
The button on the left is the power button. A yellow
indicator light on the top left of the controller will glow
when the controller is ’On’.
Functions - Handheld V Plow
The hand held controller contains all of the control
functions necessary for the operation of your Sno-Way
snow plow.
The curved rocker switch in the center of the touchpad
controls the ‘Raise’ and ‘Lower’ functions. Pressing the
forward portion of the rocker switch will ‘Raise’ the plow.
Pressing the rearward portion of the rocker switch will
‘Lower’ the plow.
There are four raised switches that surround the
‘Raise-Lower’ rockers switch. To move the plow so both
wings angle right press the two right switches at the same
time. To move the plow so both wings angle left, press the
two left switches at the same time. To ‘Scoop’ or ‘Vee
Forward’ press the top two left and right switches at the
same time. To ‘Vee Backward’ press the bottom two left
and right switches at the same time.
Either wing can be moved independently. To move the
right wing forward, press the top right button. To move the
right wing backward, press the bottom right button. The
left side operation is the opposite of the right side.
The round button in the lower center is the ‘Down
Pressure’ button. Pressing the button will turn on the
down pressure, and a red indicator light in the center of
the switch will glow. Pressing the button again will turn the
down pressure off and return the plow into float mode.
The round button in the lower right is the ‘On-Off’ switch.
A green indicator light in the center of the button will glow
when the controller is ‘On’.
