4.9 IGV
The IGV assembly consists of movable vanes and a motor. The IGV assembly is a variable-angle guiding device that is
used to control capacity at low-load conditions. The IGV position can vary between 0 degrees (closed/perpendicular
to flow) and 90 degrees (open/parallel to flow). The vane angle is determined by the BMCC and controlled by the
Serial Driver. The Serial Driver uses +15VDC to control the IGV stepper motor.
