Automatic shutdown
The
DLoG Config
program is used for the configuration of the automatic shut down under
MS-Windows.
The DLoG Config manual is available on our websites.
The configuration under Linux is explained in the “Advantech Linux Manual”.
Please contact our Technical Customer Support if required.
10.6.1.
Functional description
The DLT-V83 is equipped with an automatic shutdown module.
If wired up accordingly, the DLT-V83 conveniently switches off together with the vehicle’s ignition
(NOTICE: Ignition signal with DC devices only). As disconnecting the power supply during operation can
lead to data loss, the operating system needs to be shut down normally using the appropriate hardware
and software installed on the system when the ignition is switched off.
The DLT-V83 is connected to the vehicle with three supply cables.
DC+ and DC- are directly connected to the power supply of the vehicle, the connection is of course run
through fuses. The supply voltage connected is then linked to the DLT-V83’s ignition input via a switch,
for example, the key switch of the ignition (also with a fuse).
10.6.2.
Sequence
When the vehicle ignition is turned on or the DLT-V83 <Power> button is pressed, the DLT-V83 checks
its internal temperature and runs a test to confirm that the automatic shutdown function is working.
If this check of the environmental conditions is successful, the DLT-V83 starts the operating system
normally.
Once these checks have been successfully completed, the DLT-V83 starts the operating system. No
environmental conditions (e.g. the internal temperature of the device or the state of the ignition input) are
checked for three minutes during startup.
After three minutes, the DLT-V83’s internal temperature and the state of the ignition input are constantly
monitored.
If the DLT-V83’s internal temperature reaches a critical level, a controlled shutdown of the operating
system is carried out. The computer will remain switched off until the temperature is once again within
the permitted range.
If the ignition input is
grounded or isolated during normal operation of the DLT-V83, the device will switch
to a delayed shut-off state.
The device will continue to operate normally in this state until the shut-off delay (e.g. 15 minutes) has
elapsed.
If the ignition is turned on again during this shut-off delay, the DLT-V83 will revert to a normal
operational state.
Once the shut-off delay (after run time) has elapsed, the operating system will shut down and the device
will automatically shut down (e.g. after three minutes or a signal from the operating system).
