5.5.2 How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By activation of the 'Reset error buffer' command in the
SAM menu.
• When you transmit the code 0 6 2 5 9 9 with a standard
remote control transmitter.
5.5.3 Error Codes
Table 5-1 Error code overview
Notes:
• 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.
• 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).
5.6 The Blinking LED Procedure
Via this procedure, you can make the contents of the error
buffer visible via the front LED (orange colour).This is
especially useful when there is no picture. When no errors are
present, the LED will stay green.
When the SDM is entered, or when code 0 6 2 5 0 0 is entered
with the remote control, the LED will blink the contents of the
error-buffer.
Error-codes ≥ 10 are shown as follows:
1. n long blinks of 750 ms, which is/are an indication of the
decimal digit,
2. a pause of 1.5 s,
3. n short blinks (n = 1-9),
4. when all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
5. the sequence starts again.
Example of error buffer: 12 9 6 0 0
After entering SDM:
1. 1 long blink of 750 ms followed by a pause of 1.5 s,
2. 2 short blinks followed by a pause of 3 s,
3. 9 short blinks followed by a pause of 3 s,
4. 6 short blinks followed by a pause of 3 s,
5. 1 long blink of 3 s to finish the sequence,
6. the sequence starts again.
