Main Functions

1. Distributes regulated control power to adjacent drive‑logic boards inside the Mark V drive cabinet. Routes isolated SCR gate‑drive trigger pulses from DMCB processor board to power‑bridge thyristor assemblies.
2. Conditions and routes CT current‑feedback and DC‑field voltage‑feedback measurement signals back to control‑processor boards for closed‑loop excitation‑drive regulation. Processes group‑isolated dry‑contact interlock‑status signals for drive‑permissive and fault‑trip logic.
3. Integrated surge‑filter networks suppress field‑transient noise; hardware fuses localize short‑circuit faults to limit cascaded component damage. On‑board LED indicators support on‑site commissioning and fault‑isolation measurement.

Installation & Wiring Requirements

1. Cut off complete rack low‑voltage power and high‑voltage excitation‑drive power before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Secure DS200DPCBG1AAA onto cabinet stand‑offs. Reproduce jumper‑settings exactly matching original‑board hardware configuration. Firmly seat all field‑wiring terminal blocks and stab‑type COREBUS system‑bus connectors.
3. All power‑circuit and field‑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. Verify power‑rail LED indicators. Measure feedback‑signal values from controller diagnostic menus. Complete static gate‑pulse verification test before applying high‑voltage power. Validate excitation‑drive closed‑loop regulation and interlock‑trip‑logic response.
5. Replacement note: Incorrect jumper‑configuration or loose connections will cause gate‑pulse loss, feedback‑signal distortion, SCR‑stage damage or turbine‑generator‑trip events. Full‑system commissioning and protection‑logic verification test is mandatory before putting turbine‑generator excitation‑control or static‑starter into service.
