Alarm reading/display
7.2
7.2.1
Displaying the alarm (P3.0)
The last three alarms stored in the FLASH memory of the PCB can be displayed:
Enter the diagnostic mode (para. 6.1).
Irrespective of the type of circuit board and of the configuration, use sensor S1 to select
the LED (see figure opposite) and the display indicates the last alarm.
To display previous alarms, touch the sensor closest to the START/PAUSE sensor in
sequence (as shown in the figure)
To return to the last alarm, touch the START/PAUSE sensor.
7.2.2
Displaying the alarm (P6)
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 red light indicates the first digit of the
alarm code (family).
START/PAUSE button indicator with yellow light indicates the second digit
of the alarm code (number inside the family).
These two LEDs can be found on 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).
7.2.3
Example of alarm display
If we take alarm E43 (problem with the door safety TRIAC) as an example; the following will be displayed:
The sequence of four flashes of the START/PAUSE button with the red light indicates the first number E
The sequence of three flashes of the START/PAUSE button with the yellow light indicates the second number E4
