Main Functions

1. Local human‑machine interface for Mark V turbine‑control system: displays turbine speed, load, process analog values, alarm‑fault codes via LED digit tubes and status‑LED array.
2. Eight physical keys realize local operation: parameter browsing, set‑point modification, alarm reset, operating‑mode switching and diagnostic‑menu navigation.
3. Exchanges real‑time data, set‑point commands and fault‑alarm information with Mark V CPU boards over system backplane. Two configurable jumpers adjust display brightness and communication‑parity parameters.
4. Visual status indication assists commissioning, daily monitoring and on‑site fault‑diagnosis maintenance.

Installation & Wiring Requirements

1. Cut off rack control power before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Secure DS200KLDBG1ABC to cabinet panel with mounting screws. Reproduce jumper‑configuration exactly consistent with original‑board settings. Ensure dual vertical backplane pin‑headers are fully mated.
3. All system‑bus wiring must strictly follow Mark V system‑wiring drawings. Reliable protective‑earth connection for control cabinet is mandatory.
4. After replacement: Restore rack control power. Verify LED display brightness, status‑lamp indication and every keypad‑key response. Confirm local parameter‑write‑in function works normally. Cross‑check display data consistency with controller internal diagnostic menus.
5. Replacement note: Wrong‑jumper‑setting or poor backplane‑contact will cause display‑data disorder, keypad‑input failure or loss of local‑operation function. Full‑system HMI function verification test is mandatory before turbine unit putting‑into‑service.
