Temperature monitoring/display
Three temperature sensors monitor the temperature of the device at several positions:
● Processor temperature
● Temperature close to the RAM ICs/chips
● Temperature in proximity of the air inlet
A temperature error is triggered under these circumstances:
● The configured low threshold for the temperature has been violated.
● The configured high threshold for the temperature has been violated.
A temperature error causes the following reaction:
Reaction
Option
The DiagBase or DiagMonitor software alerts the user.
None
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
