Electronic ControlsLight Control ModuleThe light control module is amultifunctional package thatencompasses four critical controlswithin one easy-to-install, spacesaving unit. Controls include a highcurrentrotary switch, which controlsparking lights and headlights; apush-pull feature on the switch tooperate fog lights; an adjacent highcurrentthumbwheel dimmer switchto select the desired brightness fordash lighting; and an additionalminiature rocker switch for auxiliaryhigh-current lighting functions.The light control module is acompact, sleek, operator friendly,cost effective module. The ruggedhigh-current switch design allowshigh-current loads to be handledwithout the previously required costlyrelays in the switch circuit. The snap-indesign and integrated keyed connectormake installation easy, and thecompact design uses little valuabledashboard space.HVAC Motor ControllerThe HVAC motor controller efficientlycontrols heating and ventilation andinterfaces with the vehicle’s VECU toadjust the speed of the HVAC blowermotor. There are two connections inthe controller, one to the load throughthe harness and another to the VECU.The signal from the VECU controls themotor speed and creates a soft startthat will suppress any inrush duringthe motor’s start up.The HVAC motor controlleroperates at 12 or 24V and drives DCmotors up to 30A. It provides overvoltageprotection, up to 100V fortwo minutes, meeting automotiverequirements for EMC, vibration andshock. These features help extend thelife of the HVAC unit and preventthe nuisance blowing of fuses or circuitbreakers. The HVAC controller issealed to IP68, to protect it from theextreme environmental conditions subjectto the blower housing. The HVACMotor Controller is compact and usesfewer components and connectionsthan traditional motor control devices.22
