18.2.1 Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the START / PAUSE button red and green lights
(0.5 seconds on, 0.5 seconds off with a 2.5 second pause between sequences).
•
START / PAUSE button indicator with a red light → indicates the first digit of the
alarm code (family)
•
START / PAUSE button indicator with a green light → indicates the second digit
of the alarm code (family internal number)
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).
18.2.2 Example of alarm display
Let us take alarm E43 (problem with the door safety TRIAC) as an example; the following will be displayed:
•
a sequence of four flashes of the START / PAUSE button red light indicates the first number E
•
a sequence of three flashes of the START / PAUSE button green light indicates the second number E4
