Theory of Operation
1. The Sno-Way ProControl™ Operating System
includes two key components. The first is a hand held
transmitter. When a switch is actuated, the ProControl™
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™ system is
the receiver module on the plow. It receives the signal
from the ProControl™ transmitter and processes the
signal to open or close 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 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 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.
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 wired ProControl™ systems, a low voltage power
circuit leads from the receiver to the ProControl™
transmitter. This powers the circuit board of the
ProControl™ 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.
ProControl™ Operation
Basic Functions – All Plows
The ProControl™ transmitter contains all of the control
functions necessary for the operation of your Sno-Way
snow plow.
1. The round button below the LCD screen and to the
left (Figure 1-5, A) is the power button. Press and hold
the power button for approximately two seconds to turn
on the control.
NOTE: If no receiver module is paired with the transmitter
or there is no power to the paired receiver module, the
transmitter will beep and display “lost connection” on it’s
LCD screen.
