Main Functions

1. Real‑time sampling and galvanic isolation conversion of converter DC‑link high‑voltage signal.
2. Hardware‑level fast over‑voltage / under‑voltage detection, independent of main‑processor software logic.
3. Output hardware fault trigger signal to control system to execute trip sequence once voltage threshold exceeded.
4. Send scaled analog measuring data to main processor for closed‑loop control and high‑voltage monitoring.
5. Board‑level self‑diagnosis: detect sampling‑circuit abnormality and board power‑supply failure, report fault codes to converter system.
6. LED status indication:
   • Green LED：Power supply normal, board logic healthy
   • Yellow LED：High‑voltage sampling signal active
   • Red LED：Over‑voltage / under‑voltage fault / sampling channel fault / board hardware fault

Installation & Wiring Requirements

1. Cut off cabinet total power before replacement. Insert XVC770BE101 into assigned rack slot and tighten mounting screws. Hot‑swap is strictly forbidden.
2. Connect DC‑link sampling cables and fault‑signal cables strictly per wiring drawing; strictly separate high‑voltage sampling cables and low‑voltage signal cables to reduce electromagnetic interference.
3. Cabinet protective grounding shall comply with ABB ACS6000 / Megadrive‑LCI grounding specification.
4. After replacement, confirm firmware compatibility, complete high‑voltage sampling calibration and over‑voltage protection simulation test before commissioning.
5. Replacement note：Cross‑version substitution requires hardware‑firmware compatibility confirmation.
