7. Plug the mains adapter in a mains outlet, and switch the
interface 'ON'. The green and red LEDs light up together.
The red LED extinguishes after approx. 1 second while the
green LED remains lit.
8. Start the ComPair program and read the 'Introduction'
chapter.

Error Codes
5.5.1
Introduction
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error has occurred, the error is added to the list of
errors, provided the list is not full or the error is a protection
error.
When an error occurs and the error buffer is full, then the new
error is not added, and the error buffer stays intact (history is
maintained), except when the error is a protection error.
To prevent that an occasional error stays in the list forever, the
error is removed from the list after 50+ operation hours.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
5.5.2
How to read the Error Buffer
Use one of the following methods:
•
On screen via the SAM (only if you have a picture).
Examples:
–
0 0 0 0 0: No errors detected
–
6 0 0 0 0: Error code 6 is the last and only detected
error
–
9 6 0 0 0: Error code 6 was first detected and error code
9 is the last detected error
•
Via the blinking LED procedure (when you have no
picture). See next paragraph.
•
Via ComPair.

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
190600
detection circuitry can also lead to a protection).
There are various errors:
2
•
I
C device errors.
2
•
I
C bus errors.
•
Protection errors.
•
Errors not related to I
–
Black Current Loop Error (error 28): detection of a
continuous fail of the black current stabilisation loop of
the HOP.
–
FALCONIC Error (error 26): at start-up, after
initialisation of the PICNIC, the presence of the
FALCONIC can be checked.
–
Eagle Error (error 27): at start-up, after initialisation of
the PICNIC, the presence of the Eagle can be
checked.
