Troubleshooting
This section provides information on the action needed when the device malfunctions.

switch off automatically:
D
Input voltage too high / too low
D
Internal voltages too high / too low
D
System internal temperature too high / too low

Behavior at temperature limits
If the system temperature rises too much during operation, the MCU will first reduce
the generation of heat in the device. One of the ways this is achieved is by lowering the
display brightness. This mode can be recognized by the flashing
!
(Error) LED.
In this case, check that there is sufficient air circulation at the device rear panel and
make sure that the device is not covered by objects.
If the system temperature drops back down, the device will automatically revert to
normal operation. However, if the system temperature continues to rise, the display will
additionally switched off. This state can be recognized by the quickly flashing
!
(error)
LED.
If the system temperature continues to rise further, the IPC will be switched off. It will
then not be possible to switch the IPC back on until it has cooled down sufficiently.
If the system temperature is generally too high, the device will not switch on. Likewise,
if the system temperature is generally too low, the device will not switch on then either.
The device will also switch off automatically as soon as the system temperature drops
below the permissible value.
Excessively high or low system temperatures will be indicated by an error code.
For areas with high or low ambient temperatures, an extended temperature range is
offered as an option for some Industrial PCs. Please contact the noax hotline to find out
more about this.
