supplied to the motor. Short and long flashes are used
to indicate values from 0 to 100 percent.
• 0% is displayed as an off LED.
• 1 – 99% are represented by a series of long flashes
followed by short flashes, whereas each long flash
adds 10% and each short flash adds 1%.
• 100% is displayed as a constantly lit LED.
The following tables provide mapping from input
signal to fan airflow for each fan type and size.
Additional fan settings can be determined by
interpolating from the tables.
