Adjusting Body Raised Proximity Switch (Tip-to-Dump Units)
The body raised proximity switch is ACTIVATED when the plate welded to the underside of the
body loses contact with the chassis. The proximity switch then triggers the “Body Raised” warning
message to appear on the MDM display screen. Upon returning the body to the seated position, the
body raised proximity switch
is DEACTIVATED and the “Body Raised” warning message is
disappeared from the MDM display screen.
Location:
The body raised proximity switch is center mounted on the curbside chassis frame rail.
