5.2. Alarm signals
In case of alarms, the board normally activates the following actions:
the relative alarm code is signalled on the display. In particular, the display control alternates the alarm code and the
temperature normally displayed;
the alarm led switches on;
the relay alarm is activated.
For certain alarms and signals, the led and/or the relay is not activated. By pressing any key, the relay deactivates (if active) and the
led flashes, while the display alarm code continues to be displayed. The led switches on and the alarm code disappears only when the
cause that generated it is found. Table 8 reports in detail the descriptions of each alarm and the actions undertaken in this respect.
Table 7 – Alarms description.
