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).
• START/PAUSE button indicator with red light → indicates the first digit of the
alarm code (family)
• START/PAUSE button indicator with green light → indicates the second digit
of the alarm code (number within 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 LEDs (user interface not configured).
