Circuit Overview
The brush motors are powered from the power module. The power module controls the K2 relay, which
provide battery+ power to the motors. The power module then applies PWM control to the negative side of
the motor, including soft-start at startup. The power module monitors the health and performance of the
motors and reports this information back to the main controller. The optional side sweep motor is controlled
in the same manner.
The deck lift actuator is powered from the power module, which needs to reverse the polarity to this motor in
order to raise and lower the deck in very small amounts to maintain pressure. The signal from the controller
is reversible Pulse-Width Modulated (PWM).
