Model 9600/9700 Swing-Reach ® Lift Truck
Section 8. Theory of Operation Functional Operation
are activated, indicating the mini lift is fully lowered. Lift decelerates as the Load Handler approaches full elevated height. Lower decelerates as the Load Handler approaches the fully lowered position. The TM combines the height of the main and mini-masts and updates the display with the actual height of the forks.
Options Some available options can restrict normal truck operation.
Weight Calculation Main Weight Sensing The TM calculates weight based on input from the pressure transducer at port G1 on the Main manifold.
Mini Weight Sensing The TM calculates weight based on input from the pressure transducer at port G2 on the Main manifold.
Temperature Sensing •
Tractor Manager - calculates Load Handler Motor (LHM) temperature based on input from the LHM temperature sensor. The LHM cooling fan is activated when the motor temperature reaches 103°F (39.5°C).
•
Lift Power Amplifier - monitors its internal heatsink temperature sensor and the Lift Motor temperature sensor. At 185°F (85°C), the LPA goes into thermal limiting. At 203°F (95°C), the LPA shuts down. • Lift Motor - At 311°F (155°C), the LPA disables lift. Lower is allowed.
•
Traction Power Amplifier - monitors its internal heatsink temperature sensor and the Traction Motor temperature sensor. At 185°F (85°C), the TPA goes into thermal limiting. At 203°F (95°C), the TPA shuts down. • Traction Motor - At 311°F (155°C), the TPA linearly reduces travel speed. At 374°F (190°C), the TPA limits travel to 1.0 mph.
