13.3
Display a temperature fault by means of the SOM application
Cause
Temperature errors do not occur during the normal approved use of the device. Should the
"TEMP" LED indicate a temperature fault by changing from green to red, please check:
•
Are the fan apertures covered?
•
If the fan has failed (check speed display in the SOM)?
• Is the ambient temperature higher than the allowed value (see technical data)?
• Is the total output of the power supply within the specified limit?
•
Are the heatsinks inside the PC covered with dust?
Remedy
The temperature fault is stored until the temperature drops back below the temperature
threshold and you acknowledge the error message in the SOM application.
• Click on the button with the "small broom" icon.
When the error message has been acknowledged, the "TEMP" LED goes out and the
SOM application switches to the title page and the "SOM" symbol on the status bar
changes from red to green.
• Restart the PC, if you have not installed the SOM application.
