4.1 Signalling LEDs meanings
On the electronic control board of each e.DO joint there are signalling LEDs, whose
lighting can be used to identify any anomalies or faults on the board itself.
The meaning of various signalling LEDs is given below:
– Orange LED
• blinking, frequency 1 Hz = joints board correctly functioning, correctly
communicates with the Raspberry;
• blinking, frequency > 1 Hz = no communication;
• off = board not powered or not functioning
– Red LED
• off = OK board, no malfunction or error (Fault);
• on = presence of an error (Fault) due to intervention of collision detection
system (“Collision Detection”) or “Following Error”.
To access the electronic board, it is necessary to remove the perforated plastic cover
installed on each joint.
