The Pumping Unit Automatic Control System Cabinet, Type SHSAU-NU, is designed for the automatic and cost-effective control of electric drives in various pumping units. It supports a wide range of pump capacities from 1.5 to 160 kW and can manage an unlimited number of pumps. The system provides soft startup and stop, parameter regulation, signaling, diagnostics, protection, and both local and remote control.

Operation Modes
The system offers three control modes:

Remote Automatic Control (RAC): Utilizes industrial CAN interface or discrete electrical signals for control and state alarms. It includes pressure and speed control modes.
Local Automatic Control (LAC): Activated by switching to 'LAC' mode, it offers pressure and level sensor control.
Local Manual Control (LMC): Allows manual control of all mechanisms, useful for commissioning, repair, and diagnostics.

Design and Structure
The SHSAU-NU is a metal cabinet with a front door and viewing window. It includes monitoring and alarm controls, a 'Stop' button, and a light switch. Cooling is provided by a fan, and air heating is available for low temperatures. The system can be customized for specific client or technological requirements and is suitable for severe operational conditions.
