The auto sync system is the operator-controlled portion of the air control circuit. The auto sync system can have either manual or electric switches that direct pressurized air to control the CAF system modes. The operator-controlled modes are:
- Unload
- Auto/Run
- Fixed/Run
Unload Mode – whereby no air is requested for compression. (used for NAF or flushing).
Auto/Run Mode – Whereby air compression is requested to match the solution pressure (For making CAF)
Fixed/Run Mode – whereby air compression is requested at the fixed or maximum pressure (generally factory set at 150 psi) regardless of the solution pressure. (used for air only applications including special air powered tools).
The air control circuit also has automatic functions including monitoring the water pressure in the PBV and in the operation of the AIV to bring air into the compressor.
