ABB’s product data identifies 3BHE003604R0102 as UF C765 AE102:EAF; EAF-BOARD COATED, with a 0.20 kg net weight and 0.22 kg package weight. ABB’s PCS6000 service manual lists UF C765 AE102 / 3BHE003604R0102 as the EAF control component in the DRU and marks it as a serialized replacement item.
Module 3: Technical Intro & Downtime Impact
A failed control board in the PCS6000 drive rectifier unit can prevent the converter from completing its normal control sequence even when the high-power semiconductor hardware is otherwise intact. ABB UFC765AE102 / 3BHE003604R0102 is specifically identified in ABB’s PCS6000 service documentation as the EAF component in the DRU. The part is serialized, so replacement control should include exact identity and traceability checks rather than treating the board as an interchangeable generic PCB.
For MTTR planning, the strongest verified data are the product identity and construction: UF C765 AE102:EAF, EAF-BOARD COATED, 0.20 kg net weight, and 0.22 kg package weight. ABB’s current product record also lists 3BHE003604R0002 as the replaced product ID. Public ABB documentation retrieved here does not establish reliable standalone values for input voltage, processor speed, memory capacity, I/O count, operating temperature, or MTBF. Those figures should therefore not be inserted into a procurement specification unless confirmed by the exact PCS6000 electrical documentation. That distinction is important when a replacement board sits inside a high-energy converter.

Module 4: Dynamic Emergency Swap & Configuration Guide
1. Pre-Swap Prep — Capture the Serialized Board Identity
Apply the shutdown and LOTO procedure. The DRU is part of a high-power converter, so do not access the board until the applicable electrical isolation and discharge conditions have been verified.
Record the complete UFC765AE102 / 3BHE003604R0102 identification, serial number, PCB revision, board location, connector arrangement, and cable routing. ABB classifies this component as a serialized replaceable DRU control component. Photograph the board before removal.
2. Removal — Extract the DRU Control Board Without Disturbing Adjacent Hardware
Once the converter is electrically safe, label every connected cable and connector before disconnection. Release the board using the specified mechanical retention method and remove it from its DRU position without flexing the PCB or stressing the backplane connectors.
Inspect the removed board for discoloration, cracked solder joints, contamination, connector damage, or evidence of thermal stress. A field note: because the board is only about 0.20 kg, its low weight should not be mistaken for low system significance. It is a control component of the DRU.
3. Installation & Configuration — Match the Exact EAF Board
Install the replacement UF C765 AE102:EAF in the original DRU position and reconnect every interface according to the electrical drawing. Confirm the part number 3BHE003604R0102 before energization.
ABB’s current product record shows that 3BHE003604R0002 is the replaced product ID for this part. Therefore, when an older board is being replaced, verify the customer’s equipment documentation to ensure the R0102 revision is the approved successor for that specific configuration.
Do not assume that a matching “UFC765AE” prefix establishes complete interchangeability. The AE102 suffix, PCB revision, converter generation, and application configuration all matter.
4. Power-On Self-Test (POST) — Verify DRU Diagnostics Before Enable
Restore control power through the approved commissioning procedure. Monitor the converter HMI and diagnostic system for board, communication, or control-related faults.
Before enabling normal high-power operation, verify that the replacement is correctly recognized by the DRU and that the associated control sequence completes normally. Where the authorized test procedure permits, perform a controlled converter test and verify expected feedback and diagnostic behavior. A board that powers up without an immediate alarm is not sufficient evidence of successful replacement.
Module 5: Quality Assurance & Testing SOP
Each available ABB UFC765AE102 / 3BHE003604R0102 should pass a strict pre-shipment inspection sequence:
- OEM anti-counterfeit visual inspection — verify ABB markings, UF C765 :EAF designation, 3BHE003604R0102 number, serialized identification, coating, connectors, PCB construction, and manufacturing marks.
- Part-number reconciliation — compare the physical board against the customer’s DRU BOM and service documentation.
- Successor verification — record whether the customer’s original board is 3BHE003604R0002 or another revision and confirm that R0102 is the approved replacement. ABB lists 3BHE003604R0002 as the replaced product ID.
- Serial-number record — photograph and record the complete serial number because ABB identifies this component as a serialized DRU replacement.
- Conformal-coating inspection — verify the coated board surface for scratches, exposed areas, contamination, cracking, or evidence of unauthorized rework.
- Connector inspection — check all backplane and field connections for bent contacts, oxidation, cracked housings, or loose solder joints.
- Insulation and grounding checks — perform the applicable safety tests using procedures and test levels appropriate to the electronics assembly.
- Controlled power test — energize the board in a compatible test fixture and record supply behavior and startup status.
- Power-on self-test (POST) checking for diagnostic status — verify normal board recognition and absence of relevant DRU faults.
- Control-interface simulation — exercise the available board-level interfaces using the approved test setup.
- Protection and diagnostic verification — where supported by the laboratory fixture, simulate defined diagnostic conditions and confirm correct fault reporting.
- System communication test — verify correct communication with the associated control hardware.
- Extended operation test — run the board under representative control activity and monitor temperature, diagnostic stability, and intermittent faults.
- Final QA record — retain nameplate photographs, serial number, PCB revision, coating inspection, power-test measurements, diagnostic results, and final packaging photographs.
ABB’s product record confirms the item is a new spare part, identifies the invoice description as EAF-BOARD COATED, and gives a 0.20 kg product net weight.
Module 6: Maintenance & Reliability FAQ
Is the ABB UFC765AE102 3BHE003604R0102 a direct drop-in replacement, or does it require a firmware flash?
It is an ABB DRU replacement component, but a blind drop-in assumption is not advisable. ABB identifies the board as UF :EAF and lists it as a serialized replaceable DRU control component. Verify the converter generation, PCB revision, serial information, application configuration, and approved replacement relationship. The available ABB product record lists 3BHE003604R0002 as the replaced product ID.
Is it safe to hot-swap the UFC765AE102 while the is running?
No. Do not treat the EAF board as a hot-swappable electronics card unless the exact system documentation explicitly authorizes that procedure. The board is installed in the DRU of a high-power converter. Follow the approved shutdown, isolation, and discharge procedure before removal.
Will replacing the cause my current program to be lost?
The is identified as an EAF control component rather than the complete application controller. Replacing the board should not be described as a controller-program replacement. However, preserve the converter’s current configuration, protection settings, diagnostic records, and commissioning data before the intervention. After replacement, confirm that the DRU recognizes the correct board and completes its control sequence.
What should I verify before ordering an emergency spare?
Verify , 3BHE003604R0102, UF :EAF, the host converter configuration, the DRU position, PCB revision, and serial information. ABB’s service manual places this exact part in the DRU control-component list. Also check whether your existing equipment documentation references the predecessor 3BHE003604R0002, which ABB lists as the replaced product.
What are the warranty terms if the board fails after installation?
Warranty depends on the supplying party and purchase agreement. Confirm the warranty period, DOA coverage, test scope, and return procedure before shipment. Keep the pre-shipment QA report, serial-number photographs, PCB revision record, and commissioning diagnostics. Those records are especially useful for separating an EAF board defect from a DRU wiring, communication, or configuration fault.
