Fig. 6.3 Thermal protection - Automatic user warnings
● As soon as one of the internal thermocouples measures a temperature above
+75°Cforthersttime,asingleuserwarningisinitiated.Aslongasthehighest
temperature measured is above +70 °C and below +80 °C, no additional user warn-
ings are initiated.
● If the internal temperature drops below +70 °C after reaching +75 °C, the system
assumes that the user has performed an action, to reduce internal temperatures. If
the internal temperature reaches +75 °C again, the system assumes that there is a
new thermal problem and a new user warning is initiated.
● If the internal temperature keeps rising and reaches +80 °C, the system assumes
that a critical zone has been reached. User warnings will be sent every minute for
as long as the measured temperatures are above +80 °C. If the temperature drops
below +80 °C, the warnings sent at minute intervals stop. If the temperature rises
above +80 °C again, user warnings are initiated every minute again.
● If the internal temperature were to keep rising and then reaches +85 °C, an auto-
matic thermal system shutdown user warning is initiated, the automatic thermal
shutdown event is logged in the systems error log and the system will shut down.
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.
