Display a temperature error by means of the DiagBase application

Cause
Temperature errors do not occur during the normal approved use of the device. If the
monitoring software (DiagBase or DiagMonitor) indicates a temperature error and the symbol
in the status display changes from green to red, check the following:
● Are the fan apertures covered?
● Has the fan has failed (check speed display in the monitoring software)?
● 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 monitoring software.
● Click on the button with the "small broom" icon.
● Restart the PC if you have not installed the monitoring software.
