312 Electrical System
The control box is centrally mounted in the cab. It includes push-
buttons, toggle switches, and warning lamps. Autocar ACX has an
integrated control panel on the dashboard. Some units also have
auxiliary controls located under the curbside seat. Other units also
have external controls usually located on the body curbside.
The IFM multiplex electronic controller makes the truck more
reliable by reducing the number of wires and components. Electrical
maintenance is different from relay logic. The use of this electronic
controller enables mechanics to perform troubleshooting, which
facilitates the debugging process.
Labrie Enviroquip Group offers training on this technology. To
know more about electronic controllers and training schedule, please
call LabriePlus.
Proximity switches control packer and tailgate operations, and
provide the means for safety lockouts.
Limit switches are used where there is "large" movement between
components and the limited range of the proximity switch is not
permitted.
Harnesses connect all electrical components. They are generic and
therefore may contain wires and connectors that are not used. Make
sure unused connectors are always protected by caps in order to
avoid electrical failure.
