DLoG MPC 6
12.10.1.
Automatic shutdown process
When the ignition is switched on, the DLoG MPC 6 is supplied with power and begins
checking its internal temperature and automatic shutdown function.
Once the ambient conditions have been verified as acceptable, the DLoG MPC 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 shutdown 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 MPC 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 MPC 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).
