1. Vi Operating Mode
This parameter is used to select the means by which the compressor will control its Vi . This parameter will
only be visible if the Vi Mode option in the Compressor Configuration is set to Continuous Variable . The
options are:
• Auto
In this mode, the compressor will adjust its Vi based on a calculated optimal Vi position.
• Manual
In this mode, the compressor will adjust its Vi based on a user selected value.
2.
Vi Deadband
This parameter is used to define a range above and below the optimum Vi point or the manual Vi setting
within which no Vi adjustments will be made. This parameter will only be visible if the
Vi Mode option in the
Compressor Configuration is set to Continuous Variable . The value is measure in either percent or as a unit
less value depending on the type of compressor.
3. Vi Load-Unload Timer
This parameter is used to select the period of time that will elapse between the start of pulse signals while
the Vi slide is loading or unloading and the Vi slide position is within the range defined by a set proportional
band. The proximity of the Vi slide to the optimum position determines for which portion of the period the
compressor will be loading. The value is measured in seconds.
