Software control
Software, running on the BEP, samples the temperature on each sensor.
•
If the temperature rises, fan speed (and air flow) is increased.
•
If the temperature decrease, the fan speed decrease.
If the temperature increase over a pre-defined level for each sensor, the scanner will shut down. It will
then need to rest for a period of time, until the temperature inside the unit has decreased to an
acceptable value, before it is possible to turn it on again. If the VIVID E9 power down due to high
temperature inside the unit, it may indicate that the air filters need to be dusted or a failure situation.
