10.5 Alarms History
The controller memorizes in a suitable (non volatile) memory zone organized like the FIFO queue, the ALARM HISTORY, or rather it
could be a list of the last alarms verified.
In order to view the alarm history, choose “Show HISTORY” from the general Menu, or from the main page by pressing ESC.
Each element of the history is associated with the following information:
• progressive number for the alarm
• mnemonic code of the alarm (AL01, AL03, …)
• date and hours in which alarm has been verified.
The code for every alarm is that which is presented in the alarm table. The storage capacity of the history is 100 events.
Using the parameter PH30 (Cancel Alarm History) it is possible to eliminate from history all the elements memorized; set the parameter
to YES (1) and wait a couple of seconds until the re-reading of the default value NO (0).
Note 1. In the case where the memory capacity has reached it’s full limit (i.e. 100 events recorded) and you wish to memorize/record
another event, the first event initially stored in memory would be overwritten with the new event. The same would follow for other
elements.
Note 2. The history is enabled only if the parameter PG04=1, or if the system clock is enabled.
