Service Modes, Error Codes, and Fault Finding
EN 29 EM6E 5.
•
Via the blinking LED procedure (when you have no
picture). See next paragraph.
•
Via ComPair.
5.5.3
How to clear the Error Buffer
Use one of the following methods:
•
By activation of the “RESET ERROR BUFFER” command
in the SAM menu.
•
With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•
When you transmit the commands “DIAGNOSE” - “99” -
“OK” with ComPair (or with a DST).
•
If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4
Error Codes
In case of non-intermittent faults, clear the error buffer before
you begin the repair. This to ensure that old error codes are no
longer present. Before clearing the buffer, write down the
content, as this history can give you significant information.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).
There are various errors:
•
I2C device errors.
•
I2C bus errors.
•
Protection errors.
•
Errors not related to an I2C device, but of importance:
–
BLACK CURRENT LOOP (ERROR 28): detection of a
continuous fail of the black current stabilisation loop of
the HOP.
–
FALCONIC (ERROR 26): at start-up, after initialisation
of the PICNIC, the presence of the FALCONIC can be
checked.
–
EAGLE (ERROR 27): at start-up, after initialisation of
the PICNIC, the presence of the Eagle can be
checked.
