13.2 Reading the alarm codes
In order to read the last alarm code memorized in the EEPROM on the PCB:
•
Enter diagnostics mode
•
Irrespective of the type of PCB and configuration, turn the programme
selector
clockwise
to the
tenth position
.
13.2.1 Displaying the alarm
The alarm is displayed by a repeated flashing sequence of the two LEDs (0.4
seconds lit, 0.4 seconds off, with an interval of 2.5 seconds between sequences).
The buzzer (if featured) will sound “bips” in synchronization with the flashing of
the LEDs
.
•
END OF CYCLE
LED
→
indicates the first digit of the alarm code (family)
•
START/PAUSE
→
indicates the second digit of the alarm code (number
within the family)
These two LEDs are featured on all models (though they are
configured
differently
), and flash simultaneously.
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 a series of LEDs.
