Description
The Woodward 8440-2151 is an LS-522-5/P1 Version 2 Circuit Breaker Control and Protection Module designed for power generation and complex power-management applications. The LS-522 is the display version of the LS-5 V2 family and is configured for control and protection of two circuit breakers. The 5 A version provides three-phase plus neutral voltage measurement for system A/B and three-phase or single-phase current measurement. The module also provides discrete inputs, relay outputs, an isolated 0/4–20 mA input, CAN communication, and RS-485 communication. Configuration can be performed through the integrated HMI or an external PC.

Troubleshooting & Safety
Disconnect and isolate all applicable AC and DC power sources before installation or wiring. Circuit-breaker control equipment can interface with hazardous generator, utility, and control voltages, so follow site lockout/tagout procedures and verify the absence of hazardous voltage with properly rated test equipment.
Before replacement, verify the complete 8440-2151 / LS-522-5/P1 identification, current-input rating, breaker configuration, wiring, and system settings. Inspect terminal connections and communication interfaces for damage or contamination. Record existing configuration parameters before replacing the module.
After installation, verify voltage and current transformer wiring, discrete inputs, relay outputs, CAN/RS-485 connections, and breaker-control logic. Confirm that the configured protection and synchronization functions match the application before returning the equipment to service. Do not alter protection thresholds or breaker-control settings without following the applicable Woodward documentation and site commissioning procedure.
