About MADIC abnormal:
When the KMM901 controller becomes abnormal, a signal named CPU FAIL and INTERLOCK will be issued. These signal will turn on this light of Master controller abnormal or Airflow controller abnormal or Feed water
controller abnormal. At the menatime, it will send the same signals to sequencer controller for alarming

Experienced problem for this type controller:
Data setting unit insert cause boiler abnormal;
When ship moved from hot area (Dubai) to cold area (winter in China), all the KMM901 controller become abnormal;
Controller suddenly stop working, but after power off it works again;
The indication of SP, PV and VP has too much error even when all the meters are accurate;
In twin boiler system, the indications of the SP meter are different
