Main Functions

1. Execute core AVR automatic voltage‑regulation closed‑loop control algorithm for synchronous generator excitation system.
2. Implement excitation‑related protection logic, fault event recording and alarm processing.
3. Process analog & binary input signals, generate control output commands for thyristor power unit.
4. Support Ethernet communication, realize parameter configuration, real‑time monitoring and remote data exchange.
5. System self‑diagnosis: detect power‑supply abnormality, internal logic fault and peripheral channel failure; generate fault alarm code.
6. LED status indication:
   • Green LED：Power supply normal, processor running healthy
   • Yellow LED：Communication / control loop active
   • Red LED：System fault / protection trip alarm

Installation & Wiring Requirements

1. Cut off total power supply before replacement. Follow UNITROL1020 service manual for board replacement operation. Hot‑swap is strictly forbidden.
2. Connect measuring‑signal, binary I/O and communication cables strictly according to wiring diagram; separate high‑power cables and weak‑signal cables to reduce electromagnetic interference.
3. Equipment protective grounding shall comply with ABB UNITROL‑series grounding specification.
4. After replacement, download project parameters, verify firmware version consistency, complete regulation‑loop test and protection function simulation before commissioning.
5. Replacement note: Only apply for UNITROL1020 unit; cross‑model substitution is not allowed. Verify compatibility when swap between 3BHE029154P3 and 3BHE029153R0101.
