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:
Alarm window of the DiagBase or DiagMonitor software alerts the user.
The temperature error is saved until the temperatures have fallen below the thresholds and it
is reset by one of the following measures:
● Acknowledgment of the error message by the user with DiagBase or DiagMonitor
software
● Restart of the device
