Automatic user warnings are initiated using the following diagram (see Figure
6.2).
Figure 6.2: Thermal protection - Automatic user warnings
As soon as one of the internal thermocouples measures a temperature
l
above +75 °C for the first time, a single user warning is initiated. As long
as the highest measured temperature measured is above +70 °C and below
80 °C no additional user warnings are initiated.
If the internal temperature after reaching +75 °C drops below +70 °C, this
l
is considered as a user action to reduce internal temperatures. If the
internal temperature reaches 75 °C again, this is considered to be a new
thermal problem and a new user warning will generated.
If the internal temperature keeps rising and reaches +80 °C, it is considered
l
to have reached a critical zone. User warnings will be send every minute
as long as the measured temperatures are above +80 °C. If the temperature
drops below +80 °C the minute warnings stop. If the temperature rises
above + 80 °C again user warnings are initiated every minute.
If by any chance the internal temperature keeps rising and reaches
l
+85 °C an automatic thermal system shutdown user warning is generated,
the automatic thermal shutdown event is logged in the systems error log
and the system will shutdown.
At next power-on of the GEN series system, the automatic thermal shutdown
event will be presented to the user again and can be found in the error
diagnostics of the mainframe.
