I. Core Functions and Features
Comprehensive Parameter Monitoring
Real-time collection and display of key 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, rotational speed (for variable frequency models), running time, loading/unloading status
Consumable status: air filter, oil filter, and core of oil separator clogging 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, with significant energy-saving effects (up to 30% more energy saving compared to fixed-frequency models).
Multiple operation modes: Supports automatic, manual, and remote operation modes. Some high-end models can preset energy-saving modes, peak avoidance modes, etc., to meet different working 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 (such as excessive exhaust temperature), overpressure, motor overload, or low oil level, 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, expiration of lubricating oil) to reduce the risk of sudden failures.
Human-Computer Interaction and Communication
Operation interface: Equipped with high-definition LCD display screens or touch screens, supporting multi-language switching, intuitive and convenient operation, allowing 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.
II. Typical Control Unit Models and Compatible Machines
MK5/MK6 Controller
Compatible machines: GA series (small and medium-sized fixed/variable frequency machines, such as GA 11-37kW), G11-G160 series, etc.
Features: Complete basic functions, support for core parameter monitoring, automatic adjustment, and fault protection. Simple operation interface, suitable for small and medium-sized industrial scenarios.
Smart Controller Intelligent Controller
Compatible machines: GA VSD + series (efficient variable frequency machines), large GA series (such as GA 55-500kW).
Features: Possesses stronger data analysis capabilities, supports energy consumption monitoring, multi-machine linked control, and can be connected to factory energy management systems to optimize overall energy efficiency.
PLC-based Control System
Compatible machines: ZR/ZT series (large low-pressure screw machines), customized industrial units.
Features: Based on programmable logic controller (PLC), highly expandable, can be customized with control logic according to user requirements, supports integration with production line automation systems.
III. Maintenance and Precautions
Daily Inspection: Regularly clean the surface and heat dissipation holes of the control unit to avoid dust accumulation affecting heat dissipation; check if the connection cables are loose to ensure stable signal transmission.
Parameter Setting: Non-professionals should not modify core parameters (such as pressure upper and lower limits, protection thresholds) randomly, as it may cause abnormal equipment operation.
Fault Handling: When a fault code appears, refer to the equipment manual for interpretation or contact the Atlas Copco authorized service center to avoid盲目operation and expanding 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.th a compact structure and easy installation, power ranges of 11-160 kW, suitable for workshops, small production lines, etc., balancing performance and cost.
ZR/ZT Series
