12. Software Protection; Fig.23 Display With Error Message - BRAVILOR BONAMAT Aurora SINGLE LOW Operating Principle

12. Software protection

The machine is equipped with software protection; the software monitors all the input and
output of the machine throughout the whole process. If situations occur that are not allowed, the
software intervenes. As a result, the machine switches off and an error message appears on the
display.
The error message can be reset by turning the machine off and on. If the error message keeps
coming back, further investigation need to be done to solve the problem. To solve the problem,
it should be noted that error messages may have different causes. This means that the cause of
the problem can be a defective component. But, it can also be caused by the location (where the
machine is situated).
For possible solutions to these error messages, see the error list below.

Error 1. Not available
Error 2. Temperature in boiler too high:
• If the temperature sensor (NTC) measures a value that is outside its range (0 Ohm or
infinity), the machine is switched off and 'Error 2' appears in the display.
Error 3. Magnetic valve is open without selection:
• If the inlet valve is activated 3 times without starting a receipt or tapping hot water, there
is either a leak in the water system or the water is boiling. The machine switches off and
'Error 3' is displayed.
Error 4. Automatic BoilingPoint Program takes too long:
• If the automatic BoilingPoint program takes too long, the machine switches off and 'Error
4' is displayed.
Error 5. Water selector in wrong position:
• If the magnets on the water rotation disc are not detected by the hall sensor or the time
of detection is too long, the machine switches off and 'Error 5' is displayed.
Error 6. Magnetic (inlet) valve is opened too long:
• If the float tank takes too long to fill, whatever the reason, the machine will switch off and
'Error 6' is displayed.
Error 7. Not available
Error 8. Communication error between both circuit boards:
• Communication takes place when the machine is starting up and when it is used.
communication takes place through a flat cable between the touch screen display and
the control board. If communication fails, Error 8 is displayed.
