5.6.2 Major Faults
The DMC 3000 conducts periodic self tests every 10 minutes in Run, Pause and Sleep modes. Most of the tests
are also performed every second in Run mode. All the main functions are controlled by the microcontroller and
all the data, parameters and congurations integrity are protected by the CRC16.
The calibrations and algorithm parameters are protected by the CRC16 and saved inside a specic and dedica-
ted EEPROM. The dierent DC voltages on the electronic board are periodically measured and controlled.
If a fault is detected, an alarm is generated and a message is alternately shown with the measure on the display.
A major fault prevents the DMC 3000 from going into RUN mode
