(1) The former part number listed is for reference only and may differ.The new software is available in the form of a flash file through the Caterpillar® Service Information System (SIS). A newer part number may be available. SIS Web only displays the latest available flash file.De-rate Timer Strategy
The alarms signal a de-rate which occurs if a generator set is operated at above rated load for an extended period. The engine de-rates after 1 hour of operating above 100% generator set rating or 90% engine capability. The total accumulated limit is 1 hour within 12 hours of resetting at 12:00 am or 12:00 pm. The yearly limit of times allowed to operate of rated capacity is 25 hours and resets on January 1.When there are 5 seconds left on the hour counter, the engine Electronic Control Module (ECM) sends the 7426-1 through a Diagnostic Message 1 (DM1) over the J1939 Data Link to the panel. The Marine Engine Control Panel (MECP) panels read this alarm and drive a digital output. The PMS system reads this output and adjusts the load accordingly.Panels that are not Caterpillar made can read the 7426-1 over the J1939 Data Link and communicate this alarm to the load management system to adjust the load.Third-party panels can monitor the following counters:
SPN 7426 starts decrementing from 60 minutes. The de-rate induced by this counter resets at 12:00 am and 12:00 pm.
SPN 7719 starts decrementing from 1,500 minutes. The de-rate induced by this counter will reset on January 1 of the following year.That table below contains the explanation of de-rate time display event codes.
