Warnings and error messages of
the LEDs This section explains the meaning of the indications on the LEDs in case of warnings and
errors and how you can react to them.
The procedure for troubleshooting varies for warnings and errors only in the
last step: If there is an error, you must re-start the SC300 after rectification.
Cease operation if the cause of the malfunction has not been
clearly identified.
Stop the machine if you cannot clearly identify or allocate the
error and if you cannot safely rectify the malfunction.
