OM3020.3 02/01 Operation - Section 3 Instrument Panel & Indicator Lights Page 3-39 A6. NO PROPEL The RED “No Propel” light indicates a fault has occurred which has eliminated the propulsion capability. If this condition occurs, the operator should safely stop the truck, move Selector Switch to Neutral, apply the Park Brake, shutdown engine, and notify maintenance personnel immediately. B6. PROPEL SYSTEM @ REST The amber “Propel System @ REST” light is used to indicate that the AC Drive System is de-energized and propulsion is not available. This light is activated when the instrument panel REST switch is turned “On” and the AC Drive System is de-energized.

The three “LINK ENERGIZED” lights (one on rear wall of operator cab, and two on the deck-mounted control cabinets) should NOT be illuminated at this time. C6. PROPEL SYSTEM NOT READY The amber “PROPEL SYSTEM NOT READY” indicator light functions during start-up much like the hourglass icon on a computer screen. This light indicates the computer is in the process of performing the self-diagnostics and set-up functions at start-up. Propulsion will not be available at this time. D6. REDUCED PROPULSION The amber “Reduced Propulsion” light is used to indicate that the full AC Drive System performance in propulsion is not available.

At this time, the only event that should activate this light is the use of “Limp Home Mode”. This mode of operation requires a technician to enable. E6. RETARD AT CONTINUOUS LEVEL The amber “Retard Continuous” light indicates the retarding effort is at the continuous level. For a limited period of time, the retarding effort can exceed this level.
