Woodward Vertex Compressor Control System: Function, Application, and Installation Details

4.3 Performance Control and Load Allocation

The performance controller can achieve pressure or flow control through PID regulation.

The load distribution function allows multiple Vertex controllers to communicate through Ethernet, coordinate the output of each compressor, and maintain stable pressure in the common main pipe.

Operation interface and user permissions

5.1 Operation panel

Vertex provides an intuitive graphical user interface that supports navigation keys, soft keys, and hard key operations. Users can use the interface to:

Running status monitoring

parameter adjustment

fault diagnosis

View data records

5.2 User Permission Levels

Operator level: Only allows viewing of operational status and basic operations.

Service level: capable of calibration, parameter tuning, and forced output.

Configuration level: Can enter configuration mode and modify system parameters (password required).

Fault diagnosis and maintenance

6.1 Common fault codes

The system provides fault diagnosis information through LED indicator lights and software interface, such as:

CPU malfunction (red constantly on)

RAM test failed (flash code 2,1)

Watchdog not enabled (flashing code 2,10)

6.2 Maintenance Suggestions

Perform calibration verification every 24-36 months.

The backup equipment is powered on for 3 hours every 24-36 months to activate the electrolytic capacitor.

The battery life of the real-time clock is about 10 years and needs to be checked regularly.

Application cases and typical configurations

The Vertex control system is suitable for various compressor application scenarios, including:

Single stage single valve compressor

Double stage double valve compressor

Multiple parallel compressor systems

Quenching control in refrigeration cycle

The system can be flexibly configured according to actual process requirements, supporting customized control logic and I/O expansion.
