11.3 Flashing error codes
Whenever a fail condition becomes active, the red alarm lights continuously or shows a

If the error light is on continuously, this indicates a problem with the embedded

identify the error flash code and consult the table in Decoding system status words on

There is a sufficient off period between each subsequent cycle repetition to clearly mark
the start of a new flash sequence. The duration of a long flash (L) is equal to 3 times the
duration of a short flash (0.5 s).
