(1) Magnetic assembly (2) Body up or down switch | |
The body up or down switch is located on the inside of the left frame. The magnet assembly is connected to the dump body. When the dump body is raised, the body up or down switch sends a signal to the Electronic Programmable Transmission Control (EPTC II). The signal indicates that the dump body is in the UP position. When the dump body is lowered the magnet assembly will pass in front of the body up or down switch and a signal will be sent to the EPTC II. This signal indicates that the dump body is DOWN.
The body up or down switch is used to limit the top gear while the dump body is up. The EPTC II comes from the factory with the top gear value that is set to FIRST gear. The transmission will not shift past FIRST gear until the dump body is down. The top gear value is programmable by utilizing the Electronic Control Analyzer Programmer (ECAP) or the Electronic Technician (ET). The top gear value can be changed to SECOND gear, THIRD gear, or FOURTH gear.
The signal from the body up or down switch is used to provide warnings to the operator when the truck is moving with the dump body UP.
