Spreader Control System
The control unit is able to drive in a independent way auger speed and spinner speed. The speeds control system operate in open loop mode. The speeds regulation is made by the potentiometric panel. The display shows the speed percentage of spinner (SPREAD) and auger (UNLOAD); moreover in display total working hours is shown. The ON/OFF switch switches the electronics on and off. The MAX button (arrow UP) temporarily sets spinner and auger speed at maximum value. The LIGHT switch is used to drive an auxiliary lighting system. It is available also an on/off output to control Salt Water Pump (AUX switch).
It is possible to have a spread system able to set the unload quantity as a function of the traveling speed (feedback on the truck wheels). This option is suitable to keep salt spread density constant at any traveling speed. Vehicle speed can be determined with an auxiliary GPS antenna.
With the push buttons on the Canview4 display, it is possible to choose the setting menu to regulate min/max output currents, and the PWM frequency.
The salt spreader system is based on the MDE control card for the PWM power outputs and on the Canview4 colour display as user interface
