DLoG MTC 6
12.5.1.
Automatic switch-off process
When the ignition is switched on, the DLoG MTC 6 is supplied with power and begins
checking its internal temperature and automatic switch-off function.
Once the ambient conditions have been verified as acceptable, the DLoG MTC 6 starts
the operating system just like normal.
During the first three minutes of the start-up phase, none of the ambient conditions, such
as the internal temperature or the
Ignition
input status, are checked. This allows the
operating system and the operating software for the automatic switch-off module to fully
load without interruption.
Following this three-minute period, the internal temperature of the unit and the status of
the
Ignition
input are checked continuously.
If the inner temperature of the DLoG MTC 6 reaches a critical range, the operating
system is shut down normally and the computer remains switched off until the
temperature is back in the permitted range.
If the
Ignition
input is switched to earth potential or a potential-free source during normal
operation, the unit switches to shutdown delay time.
In this state, the device continues to operate normally until the delay time (for example,
15 minutes) has elapsed.
•
If the ignition is triggered again during this time, the DLoG MTC 6 resumes normal
operation.
•
If, however, the delay time elapses, the operating system is shut down normally by
the DLoG operating software and the unit is automatically switched off (for example,
after three minutes, or after a signal from the operating software).
