The messages are deleted by pressing the ALARM button when the alarm messages are displayed. If the causes no longer exist,
the status of the signal devices changes as follows:
•
the alarm relay changes status (switches according to the set logic);
•
the buzzer, if not silenced by pressing the ALARM button, stops;
•
the red LED below the ALARM button goes off.
If, on the other hand, the cause of the alarms is still present, the initial situation will return.

The user may decide whether to configure the alarm relay simply by enabling it (manufacturer branch, unit configuration, screen
M_CONF_DEV04) and entering the relay to assign to the alarm (manufacturer branch, unit configuration, screen
M_CONF_OUT_9).
If enabled, a delay time can be set (screen M_PROG05, PROG branch) between the activation of an alarm and the change in the
status of the signal relay.
If the time is set to 0, the activation of the alarm relay is immediate.

Press the MENU or PROG button, for the built-in terminal, and scroll the rows until reaching the alarm log branch.
All the activated alarms, attempts to reset them from the keypad, and black outs are automatically saved in the alarm log.
A maximum of 300 events can be saved, all of which can be displayed on the screen “M_AL_HISTORY1” in the Alarm log
branch.

The type of alarm, the time and date of the alarm and the number of events saved so far, as well as a progressive index number,
are all indicated on the screen.
When accessing the screen, the last active alarm is displayed. The UP and DOWN buttons can be used to check the previous
alarms.
Once the maximum number of alarms has been saved, the new events replace the oldest ones.
The alarm log can be deleted from the screen “M_RESET_HISTORY” in the maintenance branch (password-protected).
Installing the default values also resets the log.
