Woodward 9907-205 | MSLC Series Handheld Programmer for ProAct/DSLC/2301 Controllers

9907-205: Product Overview

This handheld programmer is a field-deployable tool designed for the commissioning, maintenance, and diagnostic evaluation of Woodward digital control systems. It interfaces directly with ProAct, DSLC, and 2301 series controllers, which are commonly found in generator set, turbine, and engine control applications. The device plays a critical role in system integration and lifecycle management by providing engineers with the means to perform adjustments and troubleshooting at the source. Its core functionality involves reading and writing configuration parameters, such as speed setpoints and droop characteristics, and executing diagnostic routines to verify the health of I/O and control logic. The programmer belongs to the MSLC (Master Synchronizer and Load Control) series, a platform developed to integrate synchronization and load control functions into a single, portable device. The benefit of this platform is the consolidation of multiple tools into one, reducing the need for a laptop or additional test equipment in the field, thereby streamlining workflows and minimizing setup time.

Core Features & Customer Value​

The portability of this tool is a significant advantage for field personnel. It eliminates the logistical challenge of transporting a laptop and associated software to remote or confined installation sites, such as power plant control rooms or marine engine compartments. Engineers can perform critical tasks like initial controller setup, parameter verification, and real-time monitoring directly at the equipment, which reduces overall commissioning time and facilitates faster problem resolution.

Integrated diagnostic functions provide substantial value by accelerating troubleshooting. The device can test contact switch logic and monitor analog input/output signals, allowing a technician to isolate a fault to a specific component or wiring issue. This capability transforms a potentially lengthy diagnostic process into a targeted exercise, minimizing system downtime. For instance, identifying a faulty phase sensor during a synchronization attempt can be accomplished in minutes rather than hours.

Access to the control algorithm parameters through a menu-driven interface allows for precise system tuning. An engineer can adjust governor setpoints, droop percentages, and other variables to match the operational requirements of the prime mover. This direct access ensures that the control system is optimized for the specific application, whether it is baseload power generation or load-following in a cogeneration setting, leading to improved stability and efficiency.

Typical Applications​

The programmer is an essential tool for commissioning a new gas turbine generator in a combined-cycle power plant. During the startup phase, an engineer uses it to configure the ProAct speed controller, set the isochronous/droop operating modes, and synchronize the generator with the plant’s bus. The ability to make on-site adjustments ensures that the turbine meets the grid code requirements for frequency and voltage.

In a marine propulsion system, a shipboard technician relies on the device to maintain the generator sets. When a report of uneven load sharing among multiple diesel generators is received, the technician connects the programmer to the 2301 series load sharing modules. By analyzing the real-time data and adjusting the load distribution parameters, the issue can be resolved without interrupting the vessel’s auxiliary power.

For an oil and gas production facility undergoing a control system retrofit, the tool is used to reconfigure a DSLC module that manages a gas compressor. The existing control logic is modified to accommodate new safety interlocks, and the load-sensing parameters are recalibrated to align with the updated process flow diagram. This avoids the need to replace the entire control assembly, representing a significant cost saving.
