OM3037 Operation - Section 3 Operating Instructions Page 3-21 To adjust the RSC control, pull switch (11) “On” and start with dial (12) rotated toward fastest speed while driving truck at desired maximum speed. Relax throttle pedal to let truck coast and turn RSC Adjusting Dial slowly counterclockwise until Dynamic Retarding is ac- tivated. Dynamic Retarding will now be activated auto- matically anytime the “set” speed is reached, the RSC switch is “On”, and throttle pedal is released. MODULAR MINING PORT CONECTOR This connector (15, Figure 3-5) location is used if the optional Modular Mining System is installed on the truck.
DATA STORE BUTTON This button (19, Figure 3-5) is for use by qualified main- tenance personnel to record in memory a “snap-shot” of the Statex III drive system. With RSC switch “On” and dial adjusted, the system will function as follows: As truck speed increases to the “set” speed and throttle pedal released, dynamic re- tarding will apply. As truck speed tries to increase, the amount of retarding effort will automatically adjust to keep the selected speed. When truck speed de- creases, the retarding effort is reduced to maintain the selected speed. If truck speed continues to decrease to approximately 3 mph (4.8 kph) below “set” speed, Dy- namic Retarding will turn off automatically.
If truck speed must be reduced further, the operator can turn the Adjust Dial to a new setting or depress the foot op- erated retard pedal. PASSENGER SEAT The passenger seat (16, Figure 3-5) is mounted on top of the right hand portion of the Center Console struc- ture. The area beneath the passenger seat provides a cabi- net for various 24 VDC electrical components. Refer to Section “D” for service involving any of these compo- nents. If the operator depresses the foot operated retard pedal and the retard effort called for is greater than that from the automatic system, the foot pedal retard will override RSC.
SERVICE ENGINE LIGHT (Blue) The service engine light (20, Figure 3-5) will illuminate if a problem is detected by the electronic engine monitoring system. STATEX III PROPULSION SYSTEM DIAGNOSTIC CONNECTOR Electric propulsion and dynamic retarding will still be available. This 9-pin connector (13, Figure 3-5) is for use by qual- ified personnel to access G.E. STATEX III electric pro- pulsion diagnostic information and data. Refer to Section “E” for additional information. If this light is on, notify maintenance personnel so they can diagnose and repair the problem the next time the truck is in the shop for repairs or at the next PM (Pre- ventative Maintenance) interval.
KOMATSU ENGINE QUANTUM CONNECTOR This connector (17, Figure 3-5) is for use by qualified personnel to access engine diagnostic information for the QUANTUM system. Refer to engine manufacturer’s service publications for troubleshooting information. KOMATSU ENGINE CENSE CONNECTOR This 3-pin connector (14, Figure 3-5) is for use by qual- ified personnel to access engine diagnostic information for the CENSE system. Refer to engine manufacturer’s service publications for troubleshooting information. UNUSED CONNECTOR This connector (18, Figure 3-5) location is not used for this model truck.
