9.2 Temperature monitoring/display
Temperature monitoring
The temperature is recorded using temperature sensors that are installed at critical locations
of the device. A sensor monitors the process temperature, further sensors monitor critical
points below the bus module.
The flashing Temp LED indicates that the device is being operated at its limits. The following
fault reactions are triggered if one of the temperature values exceeds the set temperature
threshold:
Reaction Option
The Temp LED changes to red None
Device cooling fan switches to maximum speed (the power unit
controls its own fan)
None
SIMATIC monitoring software is activated Startup of user-defined programs
can be set
Temperature errors do not occur if the device is used as intended. If a temperature error
does occur, check for the following possible causes:
● Are the fan apertures covered?
● Is the filter dirty?
● Is the fan functioning correctly?
● Is the ambient temperature within the specified range?
● Is the total output of the power supply within the specified limit?
The temperature error is retained in memory until temperatures have fallen below the
thresholds and are reset by one of the following measures:
● Acknowledgment of the error message by the monitoring software
● Restart of the device
