12 Checking the temperature sensor and overheating
shutdown function
The machine should shut down if the airend discharge temperature (ADT) reaches a maximum of
230°F.
SIGMA CONTROL 2 will simulate a higher temperature for checking this function.
For this purpose, SIGMA CONTROL 2 automatically determines an offset value to be displayed.
During the test mode, this offset is added to the actual airend discharge temperature to cause the
machine to shut down prematurely.
In standard operation, SIGMA CONTROL 2 generates the "overtemperature" fault message when
the maximum airend discharge temperature is reached. Since the modified test temperature is 2 K
below the fault message switching point for overtemperature, the system will not generate a fault
message in test mode.
