4.2.1

Viewing the TC5 aesthetic alarm

The alarm is displayed by a repeated flashing sequence of the START/PAUSE sensor red and yellow lights
(0.5 seconds on, 0.5 seconds off with a 2.5 second pause between sequences).
• START/PAUSE sensor indicator with red light → indicates the first digit of the alarm
code (family)
• START/PAUSE sensor indicator with yellow light → indicates the second digit of the
alarm code (number inside the family)
These two LEDs are present 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.
•
Alarm code families are expressed in hexadecimals; and therefore the letters:
→ A is represented by 10 flashes
→ B is represented by 11 flashes
→ ...
→ F is represented by 15 flashes
•
Configuration errors are displayed by all LEDs flashing (user interface not configured).
