7.2.1 Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the START / PAUSE
button with red and green light (0,5 seconds on, 0,5 seconds off with a 2,5 second
pause between the sequences).
• button indicator START / PAUSE with red light → indicates the first digit of the
alarm code (family)
• button indicator START / PAUSE with green light → indicates the second digit of
the alarm code (internal number of the family)
These two LEDs are featured in all models.
Notes:
• The first letter of the alarm code “E” (Error) is not displayed, since this letter is common to all alarm codes.
• The alarm code “families” are shown in hexadecimal; in other words:
→ A is represented by 10 flashes
→ B is represented by 11 flashes
→ ...
→ F is represented by 15 flashes
• Configuration errors are shown by the flashing of all the LEDs (user interface not configured).

Example: Alarm E43 (problems with the door interlock Triac) will display the following:
• the sequence of four flashes of the START / PAUSE button with red light, indicates the first number E
