Main Functions

1. Executes high‑speed real‑time digital control algorithms for EX2000 excitation‑drive closed‑loop regulation and LS2100 LCI static‑starter firing‑sequence calculation, processes high‑speed voltage and current feedback data and outputs computed reference commands to downstream drive‑control boards.
2. Communicates over COREBUS backplane to exchange set‑point values, operating‑status data and fault‑alarm information with other Mark V core control boards. Hardware jumpers configure system‑operating modes for different generator‑and‑starter hardware configurations.
3. Front‑panel LED indicators and reset button support on‑site commissioning, fault‑isolation and maintenance measurement. Stacked daughter‑board circuits complete signal scaling, filtering and isolation for raw field‑feedback inputs before DSP calculation.

Installation & Wiring Requirements

1. Cut off complete rack low‑voltage power and high‑voltage excitation‑drive / static‑starter power before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Insert DS200DSPCH1ADA into rack slot, firmly push home to engage rear backplane connectors, lock front‑panel latches. Reproduce jumper‑configuration exactly matching the original board hardware settings. Confirm all field‑signal connectors are fully seated.
3. All control‑signal wiring must strictly follow Mark V / EX2000 / LS2100 system‑wiring drawings. Reliable protective‑earth connection for control cabinet is mandatory.
4. After replacement: Restore rack low‑voltage power first. Observe front‑panel LED power and communication status. Verify feedback‑signal sampling values from controller diagnostic menus. Perform static control‑loop test before applying high‑voltage power. Validate excitation‑drive or static‑starter closed‑loop performance.
5. Replacement note: Incorrect jumper‑configuration or poor backplane contact will result in control‑loop calculation deviation, drive‑system mis‑operation or turbine‑trip events. Full‑system commissioning and protection‑logic verification test is mandatory before putting turbine‑generator excitation‑control or static‑starter into service.
