Operation - Section 32 OM3241 Page 32-8 Operator Cab and Controls With the RSC switch in the ON position and the dial adjusted, the system will function as follows: As the truck speed increases to the set speed and the throt- tle pedal released, dynamic retarding will apply. As the truck speed tries to increase, the amount of retarding effort will automatically adjust to keep the selected speed. When the truck speed decreases, the retarding effort is reduced to maintain the selected speed. If the truck speed continues to decrease to approximately 5 kph (3 mph) below the set speed, dynamic retarding will turn off automati- cally.
If the truck speed must be reduced further, the operator can turn the dial to a new setting or depress the retard pedal. Data Storage Button Data storage button (1, Figure 32-6) is used to record a snapshot of the Statex III drive system. Passenger Seat The passenger seat is mounted on top of the right- hand portion of the center console. The area beneath the passenger seat provides a cabinet for various 24VDC electrical components. Consult the service manual for service involving any of these components. If the operator depresses the retard pedal, and the retard effort called for is greater than that from the automatic system, the demand from the pedal will override the RSC.
