6.20.1 Error codes of the status LED
Any errors or warnings occurring in the MSB box will be indicated both as an error
code by the control unit and as a blink code by the Status LED.
The blink code is preceded by a long white signal. This is followed by an error or
warning number. An error number is indicated by means of red signals, while a
warning number is displayed using orange signals (the orange signals have a strong
green tinge, however):
• Start of blink code: long white signal
• Hundreds digit: 0 ... 9 red signals for errors / 0 ... 9 orange signals for warnings
• Break: blue signal
• Tens digit: 0 ... 9 red signals for errors / 0 ... 9 orange signals for warnings
• Break: blue signal
• Units digit: 0 ... 9 red signals for errors / 0 ... 9 orange signals for warnings
The blink code is repeated cyclically.
For example:
The pressure is too high.
-> Error code = Warning 520
-> Blink code of the Status LED: White (long), 5·orange, blue, 2·orange, blue
