Theory of Operation

1. The Sno-Way ProControl II™ Operating System
includes two key components. The first is a hand held
transmitter. When a switch is actuated, the ProControl
II™ transmitter 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 ProControl II™ system is
the receiver module on the plow. It receives the signal
from the ProControl II™ transmitter and processes the
signal to open or close valves so that the hydraulic
system of the plow power unit will perform the required
operations.
3. 12V DC power is fed from the battery terminal of the
start solenoid to the individual valve solenoid coils and
the receiver module. The ground wires for the start
solenoid and valve coils 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.
NOTE: This is a ground switching system and has power
on the coils as soon as power is connected to the plow.
The receiver module energizes the coils by providing a
ground path to them.
4. On ProControl II™ systems, a low voltage power
circuit leads from the receiver to the ProControl II™
transmitter. This powers the circuit board of the
ProControl II™ transmitter and supplies the low voltage
power needed to process the signal from the switches on
the transmitter and send a signal back to the receiver on
the plow.

OPERATION

ProControl II™ Operation
Basic Functions – All Plows
The ProControl II™ transmitter contains all of the control
functions necessary for the operation of your Sno-Way
snow plow and receiver mounted salt spreader.
1. The center button just above the joystick (Figure 1-
12, A) is the power button. Press and hold the power
button for three seconds to turn on the control. To turn
the control off, hold the power button until the backlights
go out.

2. The molded joystick cap in the center of the
ProControl II™ transmitter (Figure 1-12, B) operates the
"Raise", "Lower", "Left" and "Right" functions. Pushing
joystick forward (towards the top) will "Lower" the plow.
Pulling the joystick towards the bottom will "Raise" the
plow. This is the default setting for the control. The
control can be programed to reverse the Raise and
Lower functions so that pushing the joystick forward will
raise the plow and pulling the joystick back will lower the
plow (see step 4).
3. Pushing the joystick left will cause the plow to do a
"Left" function. Pushing the joystick right will cause the
plow to do a "Right" function.
