　　TC-4000-S Other Names:

　　Input/Output Unit TC-4000-S

　　TC-4000-S Analog Unit

　　TC-4000-S Communication Unit

　　Product Series: The TC-4000-S belongs to Atlas Copco's industrial control module series, covering variants such as torque controllers, power controllers, and AC drives (e.g., TC-4000-S-ES, TC-4000-S-E), widely used in industrial fastening, power management, compressor control, and other scenarios.

　　Core Functions and Application Scenarios

　　Industrial Fastening and Assembly Control

　　Precise Torque Control: Used in automotive manufacturing (engine/chassis/body fastening), machining, electronic assembly, and other scenarios to ensure bolt/nut torque output meets process specifications (e.g., ±3% accuracy), reducing rework rates.

　　Multi-Mode Support: Supports single-step fastening, multi-step fastening, angle monitoring, and other modes to adapt to different assembly needs.

　　Data Traceability: Records fastening time, torque value, angle, and other parameters to meet ISO/TS quality traceability standards.

　　Intelligent Management: Supports multi-program storage and switching, real-time data acquisition (pressure/temperature/current, etc.), fault alarms, and diagnostics.

　　System Optimization: Optimizes energy efficiency and reduces operating costs through PID control, load/unload control, and variable speed drive (VSD) algorithms.

　　Integration Capabilities: Compatible with Modbus RTU, Ethernet, and other industrial interfaces, supporting integration with automation systems/factory management systems.

　　Power Management and Protection

　　Power Coordination: Manages the power supply to power tools (such as tightening guns and welding machines) in automated production lines, achieving stable power supply through a three-phase power input (industrial standard voltage).

　　Multiple Protections: Integrates overload, overvoltage, undervoltage, short circuit, and overtemperature protection to prevent equipment damage due to power fluctuations.

　　Modular Design: Supports cabinet installation, facilitating expansion for centralized power supply of multiple devices (such as multi-station assembly lines).

　　Compressor and Energy Optimization

　　Compressor Control: Designed specifically for screw compressors, supporting PID control, load/unload switching, and variable speed drive (VSD), real-time monitoring of pressure, temperature, and motor current to optimize energy consumption (reducing energy costs by 10-30%).

　　Remote Monitoring: Integrates with a host computer system via Ethernet/Modbus RTU interface to achieve operational data recording, trend analysis, and remote diagnostics.

　　Other Industrial Scenarios

　　General Industries: Automated production lines in industries such as machinery manufacturing, textiles, papermaking, food processing, pharmaceuticals, and chemicals.

　　Special Environments: Adaptable to harsh environments such as high temperature, high humidity, and vibration (e.g., ships, construction machinery, heavy industrial equipment).

　　Technical Parameters and Features

　　Electrical Parameters: Rated voltage is typically industrial three-phase AC (e.g., 400V/480V), protection rating IP43, operating temperature -10℃~55℃.

　　Communication Interfaces: Supports Ethernet, RS-485 (Modbus RTU), industrial bus (e.g., PROFIBUS), compatible with PLC/DCS systems.

　　User Interface: High-resolution color display screen, multi-language support, intuitively displays operating status, alarm information, and parameter settings.

　　Expandability: Modular design supports functional expansion (e.g., adding I/O modules, communication modules) to adapt to different production scales.

　　Usage Method

　　Installation and Configuration:

　　Ensure power supply voltage matching (industrial standard three-phase power supply), connections are secure and not loose, avoid squeezing or damaging cables.

　　Modular design facilitates installation in industrial control cabinets; control lines, communication lines, and sensors must be connected correctly according to the wiring diagram.

　　Operating Procedures:

　　Pre-Start Checks: Confirm power supply is normal, connectors are free of corrosion, and clean module surfaces (avoid wiping electronic components directly with a damp cloth).

　　Parameter Settings: Adjust torque threshold, preset speed, delay time, etc., via the high-resolution color display. Multi-language interface supported.

　　Firmware Updates: Regularly upgrade to the latest version to fix potential bugs and improve performance stability.

　　Maintenance:

　　Regular Cleaning: Use compressed air to remove dust and check the condition of heatsinks/fans to prevent dust accumulation from affecting heat dissipation.

　　Calibration Check: Use a standard torque wrench to calibrate torque output and adjust to zero to eliminate preload effects.

　　Mechanical Inspection: Lubricate transmission components (such as gearboxes) and check for loose or damaged sensors/connectors.

　　Precautions for Use:

　　Installation and Debugging： Must be operated by qualified personnel. Ensure power supply matching and reliable grounding, and follow the manufacturer's installation manual.

　　Environmental Requirements: Avoid humid, dusty, and high-temperature environments. Clean the cooling system (such as fans and heatsinks) regularly.

　　Safety Guidelines: Disconnect power before operation to avoid working with live equipment; comply with electromagnetic compatibility (EMC) standards to minimize external interference.

　　Summary: The TC-4000-S control indicator is a core component of Atlas Copco's industrial control solutions. With its precise control, multiple protections, modular design, and wide compatibility, it has become the preferred equipment in automotive manufacturing, machining, and compressor control industries. Strictly adhere to installation, operation, and maintenance guidelines to ensure equipment performance and production safety.
