ATLAS COPCO Injection-Type Screw Compressor Control Unit
1. Core Functions and Features
Comprehensive Parameter Monitoring
Real-time collection and display of critical operating data of the compressor, including:
Pressure parameters: suction pressure, exhaust pressure, oil separator pressure, etc.
Temperature parameters: exhaust temperature, oil temperature, and ambient temperature
Operating status: motor current, speed (for variable frequency models), running time, loading/unloading status
Consumable status: air filter, oil filter, oil separator core blockage degree
Intelligent Operation Control
Automatic Adjustment: According to the system pressure requirements, automatically control the loading/unloading of the compressor. For variable frequency models (VSD), it can achieve precise matching of exhaust volume by adjusting the motor speed, resulting in significant energy savings (up to 30% more energy savings compared to fixed-frequency models).
Multiple Operating Modes: Supports automatic, manual, and remote operation modes. Some high-end models can preset energy-saving modes, peak avoidance modes, etc., to meet different operating conditions.
Linked Control: Can achieve cluster control of multiple compressors (such as through the Central Controller system), optimizing the load distribution among units and avoiding the "big horse pulling a small cart" phenomenon.
Fault Protection and Diagnosis
Safety Interlock: When detecting abnormal conditions such as overheating (e.g., excessive exhaust temperature), it immediately triggers shutdown protection and displays the fault type through codes.
Fault Memory: Automatically records the time, cause, and operating parameters of the fault, facilitating rapid problem location by maintenance personnel.
Warning Function: Early warning for upcoming maintenance items (such as filter replacement, oil expiration) to reduce the risk of sudden failures.
Human-Machine Interaction and Communication
Operation Interface: Equipped with high-definition LCD display screens or touch screens, supports multi-language switching, intuitive and convenient operation, and allows for quick setting of target pressure, operating parameters, etc.
Data Storage: Records cumulative running time, energy consumption data, maintenance cycles, etc., providing data support for equipment management.
Remote Monitoring: Some models integrate IoT functions (such as SmartLink system), allowing for remote viewing of operating status and receiving alarm information, enabling intelligent operation and maintenance.
2. Typical Control Unit Models and Compatible Models
MK5/MK6 Controller
Compatible Models: GA series (small and medium-sized fixed/variable frequency models, such as GA 11-37kW), G11-G160 series, etc.
Features: Complete basic functions, supports core parameter monitoring, automatic adjustment, and fault protection. Simple operation interface, suitable for small and medium-sized industrial scenarios.
Smart Controller Intelligent Controller
Compatible Models: GA VSD + series (efficient variable frequency models), large GA series (such as GA 55-500kW).
Features: Possesses stronger data analysis capabilities, supports energy monitoring, multi-machine linked control, and can be connected to factory energy management systems to optimize overall energy efficiency.
PLC-based Control System
Compatible Models: ZR/ZT series (large low-pressure screw machines), customized industrial units.
Features: Based on programmable logic controller (PLC), highly scalable, can be customized with control logic according to user requirements, supports integration with production line automation systems. Fault Handling: When a fault code appears, refer to the equipment manual for interpretation, or contact the authorized service center of Atlas Copco. Do not perform any operations blindly to avoid exacerbating the fault. Firmware upgrade: Some control units support firmware updates. You can obtain the latest program through official channels to enhance system stability and expand functionality.
