Display overheated
Update to the latest available software. Check if there is any change in the airflow from a retrofitting activity in the IP panel. Check if there if the fan is dusty. Check for a cooling fan DTC. Perform cooling fan test.
What you'll see
display back-light intensity is reduced and cannot be increased manually anymore --> thermal management is activated
System reaction
System will show a pop-up and will shutdown
Diagnostic depth
Display temperature above critical temperature (> T_threshold). This fault will be checked in run-time. T_threshold depends on the serial number and performance step of the unit: - HW-Assy:2551941 and 2551942: 95°C - HW-Assy:2490025: SerialNumber < G2522000: 95°C - HW-Assy:2490025: SerialNumber ≥ G2522000: 110°C
E.g. - Colling fan damaged or dirty - On retrofitting, the thermal flow has been restricted.
