Main Functions

1. Real‑time local HMI for Mark V turbine‑control system: displays turbine speed, load, temperature, pressure, alarm‑fault codes and unit permissive‑status via 21 groups of alphanumeric LED displays and 32‑channel status‑LED array.
2. Membrane keypad realizes local manual‑operation functions: parameter browsing, set‑point modification, alarm reset, operating‑mode switching and diagnostic‑menu navigation.
3. Communicates with Mark V main CPU boards over rear 40‑pin system‑bus connector, completes bidirectional transmission of operating‑set‑point, real‑time process‑data and fault‑alarm‑information. Single configurable jumper adjusts display‑bus operating parameters; factory‑reserved test‑jumper positions shall not be altered on‑site.
4. Visual indication supports daily on‑site monitoring, commissioning and fault‑diagnosis maintenance work.

Installation & Wiring Requirements

1. Cut off rack control power before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handlingMoore Auto….
2. Secure DS200KLDCG1AAA onto cabinet front‑panel with four mounting screws. Reproduce jumper‑configuration exactly consistent with original‑board hardware settings. Confirm rear 40‑pin connection strip fully mated.
3. 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 each group of display modules and LED‑lamp status. Test every keypad key response, confirm local parameter‑write‑in function works normally. Cross‑check display read‑out against controller internal diagnostic‑menu values.
5. Replacement note: Wrong‑jumper‑setting or poor 40‑pin‑connector 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.
