API Salt Spreader Control

Features: Backlit front panel for quick and easy nighttime viewing Mounting bracket for simple under dash or console mounting Extra long bat style toggle switch for easy Blast Function access Automatic operation that automatically stops spreader when vehicle stops Fully labeled wiring harness for simple error free wiring PWM outputs are short circuit protected Front Panel Controls: Power Switch Auto/Manual Switch Momentary Blast Function Switch Conveyor Speed Potentiometer Spinner Speed Potentiometer Power On LED

Operation: Our Salt Spreader is an all solid state microprocessor controlled circuit designed to operate two hydraulic proportional valves utilizing PWM control. The requested proportional valve currents are set by the conveyor and spinner potentiometers located on the front panel. Based on potentiometer settings, the microprocessor constantly monitors the proportional valve coil currents and automatically adjusts the PMW output as required to provide a constant current to the proportional valve coils. This ensures a constant oil flow thru the proportional valves regardless of proportional valve coil temperature or any voltage fluctuation in the vehicle’s electrical system. Each proportional valve output is capable of driving a 3 amp load. The Blast Function is enabled by lifting the long bat momentary toggle switch and will instantly energize both PWM outputs to full power until the switch is released. This feature is used for spreading an extra concentration of salt at a particular location such as an intersection. The Automatic Function is enabled by lifting the Auto/Manual switch to the Auto position and will provide automatic spreader operation. The control will stop and start the spreader as the vehicle is stopped and started. If your vehicle is equipped with a Vehicle Speed Sensor (VSS) signal, the control can sense vehicle speed from this signal. Most vehicles have a VSS signal, but if your vehicle does not have one available, the control is capable of powering an additional proximately sensor which can be added to the vehicle to sense driveshaft rotation.
