Main Functions

1. Auxiliary‑status signal acquisition: Collects working‑status feedback signals from thyristor power unit, cooling system and cabinet auxiliary equipment, completes signal conditioning and filtering.
2. Earth‑fault monitoring: Realizes hardware‑level earth‑fault detection for power section, detects insulation abnormal of power valve loop, sends fault alarm to main processor.
3. Temperature‑signal processing: Samples temperature signals from power‑unit temperature sensors, transmits temperature data for over‑temperature protection logic judgment.
4. Interlock‑condition logic processing: Processes safety interlock signals, outputs permission‑related signals for power‑unit enabling, participates in hardware interlock protection chain.
5. Fault‑signal reporting: Detects signal‑line breakage, signal deviation and channel abnormality, reports detailed fault codes to main controller.
6. Board‑level comprehensive self‑diagnosis: Monitors on‑board power‑supply, signal‑processing circuit and back‑plane link status; uploads hardware‑fault‑alarm information to UNITROL6000 system.
7. On‑board multi‑LED status indication
   • Green LED：Board power supply normal, board logic running healthy
   • Yellow LED：Auxiliary‑signal acquisition & data transmission active
   • Red LED：Earth‑fault / over‑temperature / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Insert UFC765AE102 into designated rack slot and fasten fixing screws firmly. Hot‑swap is strictly forbidden.
2. Connect power‑unit auxiliary feedback, earth‑fault detection and temperature‑sensor cables strictly according to drawing; separate high‑power cables and weak‑signal cables to reduce electromagnetic interference.
3. Cabinet protective grounding must comply with ABB AC800‑PEC / UNITROL6000 system grounding specification.
4. After replacement, verify full‑system firmware compatibility with main processor board; download matching project parameters; perform signal‑channel test and interlock‑logic verification before unit commissioning.
5. Replacement note: Cannot run independently; must match corresponding main‑processor hardware and full‑system firmware version.
