In which position must the vanes be for the compressor to start according to the vane closed switch?

For a compressor to start, the vanes must be in the closed position according to the vane closed switch. This positioning is crucial because when the vanes are closed, it creates an optimal chamber for the compression process to begin.

When the vanes are closed, the compressor can build up pressure effectively, allowing for a proper flow of refrigerant or air, depending on the type of compressor. The vane closed switch acts as a safety mechanism that ensures the compressor does not start unless the vanes are in the correct position, preventing potential damage to the compressor or inefficient operation.

It is essential that the vanes be fully closed to ensure that the necessary sealing and pressure requirements are met before the compressor is engaged. This is part of a wider safety and operational protocol for many types of compression systems, ensuring reliable and efficient performance.
