7.4 Alarms log
The controller stores in a non-volatile memory the alarm history.
In order to view the alarm history, choose Show Alarm History from the general Menu or from the main page by
pressing ESC in order to view the following page:
You may press ENTER on Show Alarm History.
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 acknowledged.
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 PH18 Cancel Alarm History it is possible to delete all the elements stored in the history; 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 its full limit (i.e. 100 events recorded) and you wish to
record another event, the first event initially stored in memory will be overwritten with the new event. The same
would follow for other elements.
Note 2. The history is enabled only if the parameter PG03=1, system clock is enabled.
