8.14 Description of “ALARMS” menu
The ALARMS logbook in the MAIN MENU’ records the alarms of the controller. 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
five locations getting possible to stack five different type of alarms with the
following information:
1) The alarm code
2) The times that each alarm occurs consecutively
3) The Hour Meter value when the first event of every alarm occurred
4) And the inverter temperature when the first event of every alarm occurred.
This function permits a deeper diagnosis of problems as the recent history can be
revised.

NOTE: if the same alarm is continuously happening, the controller does not use
new memory of the logbook, but only updates the last memory cell increasing the
related counter (point 2) of previous list). Nevertheless, the hourmeter indicated
in this memory refers to the first time the alarm occurred. In this way, comparing
this hourmeter with the controller hourmeter, it is possible to determine:
- When this alarm occurred the first time.
- How many hours are elapsed from the first occurrence to now.
- How many times it has occurred in said period.
