PROBLEM
| New machine/monitor software should be installed for a new Turbo Protection Mode feature that ensures proper turbo shaft lubrication. This is achieved by the following software changes: -Engine remains in low idle for 3 seconds at start-up, regardless of coolant temperature. -After low idle hold, engine rpm remains at low idle until foot throttle or hand dial is adjusted, regardless of throttle position at start-up. -Maximum engine rpm is limited based on coolant temperature and driven via a non-adjustable software map. High Idle is not available until coolant temp is >68F (20C). The software also includes an improved warning system for Engine Air Filter Restriction. Historically only a level 1 event existed which lights the Engine Condition alert indicator amber to notify the operator of a possible issue. With this update, should the machine accumulate 15 minutes of run time with a level 1 fault active, a new level 2 event will activate. At level 2, the Engine Condition alert indicator will light red and the engine throttle will be limited to 50 full throttle. Full throttle control will not be returned to the operator until the event is cleared. Note the 15 minute timer will remain active through a key cycle. The display software needs to be updated on certain machines to show the correct message during engine warmup mode. |
