Comparison with Competing Products

When compared to competitive generator controllers such as the ComAp InteliLite series or the DEIF AGC series, the WOODWARD 9907-167 distinguishes itself through Woodward’s deep heritage in prime mover controls and fuel system integration. While ComAp offers exceptional flexibility and user-friendly programming, the WOODWARD 9907-167 often provides tighter integration with Woodward’s own actuators and speed controls, resulting in superior response characteristics and system optimization. Compared to DEIF controllers, which excel in marine applications, the WOODWARD 9907-167 offers similar maritime capabilities with additional features tailored for land-based power generation. The robust hardware construction and extended temperature range of the WOODWARD 9907-167 make it particularly well-suited for harsh environments where lesser controllers might fail, such as desert installations or arctic operations. For facilities with existing Woodward equipment, the WOODWARD 9907-167 provides seamless integration with consistent programming tools and support.

Selection Suggestions and Precautions

When selecting the WOODWARD 9907-167 for your application, first verify the specific firmware version and configuration software compatibility, as Woodward frequently releases updates with enhanced features or regulatory compliance updates. Ensure that the WOODWARD 9907-167 is correctly sized for your generator set’s voltage and current ratings, paying particular attention to the input ranges for voltage sensing and the output ratings for governor and AVR control signals. Consider the communication requirements of your installation and select appropriate options for the WOODWARD 9907-167 to interface with your SCADA or building management system. During installation of the WOODWARD 9907-167, follow strict wiring practices to separate low-level signal wiring from high-power AC circuits to prevent noise-induced malfunctions. Pay careful attention to proper grounding and shielding of analog and communication cables to maintain signal integrity. Before commissioning, thoroughly test all protection functions of the WOODWARD 9907-167 using simulated conditions to verify correct operation. Finally, always perform a complete backup of the configuration parameters for the WOODWARD 9907-167 before making any changes, allowing for quick recovery if commissioning issues arise. For critical applications, maintain a spare WOODWARD 9907-167 on hand to minimize downtime in case of unexpected failure.
