4.3.1.2 Temperature monitoring/display
Temperature monitoring
Three temperature sensors monitor the temperature of the device at several positions:
● Processor temperature
● Temperature in proximity to the RAM ICs/blocks
● Temperature of the basic module
A temperature error is triggered when one of the three temperature values exceeds the set
temperature threshold and the following reaction is initiated:
The DiagBase or DiagMonitor software is enabled
The temperature error is retained in memory until temperatures have fallen below the
thresholds and it is reset by one of the following measures:
● Acknowledgment of the error message by the monitoring software
● Restart of the device
