9907-167
Main features and advantages:
The WOODWARD 9907-167 offers a multitude of benefits that directly translate into improved operational efficiency and reduced costs. Its advanced control algorithms enable it to maintain turbine speed within ±0.25% of the setpoint, ensuring stable power generation and minimizing wear and tear on turbine components. This level of precision is crucial for applications where even minor speed fluctuations can lead to significant power quality issues or equipment damage.
In terms of energy efficiency, the module optimizes steam usage by precisely controlling extraction and admission pressures. By maintaining these pressures within optimal ranges, it reduces steam waste, leading to potential fuel savings of up to 10% in some applications. This not only cuts down on operating costs but also contributes to a more sustainable operation.
The 9907-167 also simplifies maintenance and troubleshooting. Its back panel provides easy access to input and output wiring connections, and the use of unplug – gable terminal blocks streamlines system installation, troubleshooting, and component replacement. Built – in diagnostics continuously monitor the module’s performance, flagging any potential issues early on. This proactive approach helps prevent unplanned downtime, which can be extremely costly in industries such as power generation.

Installation and maintenance:
Before installing the WOODWARD 9907-167, it is essential to verify that the power supply can deliver a stable 18 – 32 V DC. Voltage fluctuations outside this range can cause erratic control behavior and potentially damage the module. Ensure that the mounting surface is flat and suitable for front – panel installation, as uneven mounting can affect the module’s performance over time. Check that the communication interfaces (such as Modbus or Ethernet) are properly configured and that the cables are correctly terminated to prevent signal interference. It is also crucial to review the turbine’s original equipment manufacturer (OEM) steam maps and ensure they are compatible with the 9907-167‘s control algorithms. Woodward provides detailed compatibility information and guidelines to assist with this process.
For ongoing maintenance, perform monthly checks of the module’s status indicators. A steady green light on the front – panel display typically indicates normal operation, while any flashing or red lights should be investigated immediately using the diagnostic tools provided by Woodward. Every six months, inspect the electrical connections for signs of corrosion, especially in humid or corrosive environments. Tighten any loose connections to maintain reliable operation. Calibration of the module should be carried out annually to ensure accurate control of turbine parameters. Woodward offers calibration procedures and tools to assist with this task. Finally, keep the module’s firmware up – to – date to benefit from the latest control algorithm improvements and security enhancements.
