When a fault is detected, four consecutive led flashes indicate the presence of one or more error
conditions. The four flashes correspond to four possible error conditions, named E0, E1, E2 and
E3. The flashes timing diagram is reported in the diagram below. Each flash lasts
for 0.5”
(500ms)
and ha
s a period of 1”
(1s). The four
flashes train is repeated every 6”
(6s). The first flash
corresponds to E0 (error0), the second to E1 (error1) and so on. If the E0 flash is green, there is no
error, if red, error is present.
Example 1:
1
st

green
2
