Temperature monitoring/display
Temperature monitoring
Temperature errors do not occur under normal operation. If a temperature 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 until the temperatures have fallen below the thresholds
and are reset by one of the following measures:
• The error alarm is acknowledged by pressing the Info button on the SystemGuard user
interface.
• Restart of the device.
