4-1.3. Fault Detection.
4-1.3.1. General
The controller provides diagnostics information to
assist technicians in troubleshooting problems. When
a fault is detected, an alarm is recorded in the logbook.
It has a FIFO (First Input First Output) structure that
means the oldest alarm is lost when the database is
full and a new alarm occurs. The logbook is composed
of alarms with the following information:
• The alarm code
• The times that each alarm occurs consecutively
• The Hour Meter value when the latest event of every
alarm occurred
• The invert temperature when the latest event of
every alarm occurred.
This function permits a deeper diagnosis of problems
as the recent history can be revisited.
