- Industrial Engine:
- C32 (S/N: NST1-UP)
Description of Change: The new software corrects the manual purge function.
Adaptable To: The 454-3469 Engine Ratings Electronic Software Gp replaces the former 424-8929 Engine Ratings Electronic Software Gp .
The new software is adaptable back to first production on the serial numbers listed above.
The Charged Air Cooler (CAC) sensor should be wired to pin J1/26 replacing the "Auxiliary Temperature #2".
The CAC sensor input will be considered as one of the inputs for the variable pitch fan only when the CAC is installed via ET and enabled as one of the fan temp inputs.
If the CAC sensor is not installed via ET, the "Auxiliary Temperature #2" will be available and virtual CAC sensor will be considered for variable pitch fan.
The Manual Reversing Switch should be wired to pin J1/6 instead of pin J1/54 as shown in Application and Installation Guide, LEBH0009.
Update the automatic cycle time to 18 hours to eliminate the automatic purge from a typical work day.
This change is effective with serial numbers NST00133-UP.
