6.2.1. Operating Range
The Operating Range allows the user to enter a value which will represent 100% of the process output
signal (5VDC, 10VDC, or 20mA). The Operating Range Value has been set by the factory to equal
110% of the design supply flow rate, unless this value is less than the Minimum Full Scale Value
allowed for the AAON Airflow Signal Processor. The menu will display the Minimum Full Scale Value
allowed which is then entered as the Operating Range.
6.2.2. Engineering Units
A list of engineering units are available for the user to select from for display purposes to meet customer
requirements. Changing the engineering units will affect the process display and the alarm value menus.
The default setting is ACFM.
