ABB 3HAC046686-002 / 3HAC046686-003 SMB Replacement Sets

Two ABB SMB replacement records for battery-backed robot measurement systems.

Product Information

ABB 3HAC046686-002 / ABB 3HAC046686-003 are ABB SMB replacement sets for robot serial-measurement systems. They sit in the measurement chain that preserves axis-position information while the robot controller is unpowered, and they are identified by the complete ABB model and ordering record rather than by the enclosure alone.

The board association separates the two records: ABB 3HAC046686-002 is documented with RMU101 3HAC044168-001 and the IRB 6660/6600/6650 family, while ABB 3HAC046686-003 is documented with RMU102 3HAC043904-001 in the IRBT 4004/6004/7004 measurement-unit context. The measurement board and battery are therefore read together with the installed robot system before a replacement is selected.

For service identification, ABB 3HAC046686-002 / ABB 3HAC046686-003 should stay attached to the installed SMB position, board reference and robot family. That record keeps the battery-backed revolution path distinct from a similar-looking board and prevents a valid component from being assigned to the wrong measurement chain.

System Integration

ABB 3HAC046686-002 and ABB 3HAC046686-003 are selected by the installed serial-measurement architecture, not by the outer enclosure alone.

RMU101 measurement path

ABB 3HAC046686-002 is associated with RMU101 3HAC044168-001. Resolver and battery references stay with the IRB measurement chain so the controller receives the same axis-position record after service.

RMU102 measurement path

ABB 3HAC046686-003 is associated with RMU102 3HAC043904-001 in the documented IRBT 4004/6004/7004 context. The board reference identifies the measurement path that the replacement set belongs to.

Record before removal

For either ABB 3HAC046686-002 or ABB 3HAC046686-003, retain the robot family, installed board reference, SMB position and battery/cable identifiers together. This prevents a valid replacement from being assigned to the wrong serial-measurement chain.

Key Features

The defining features of ABB 3HAC046686-002 / ABB 3HAC046686-003 are their coordinated SMB replacement role and variant-specific board association.

Coordinated replacement set

ABB 3HAC046686-002 brings the RMU101 board, battery unit, cable and documented holders into one replacement record. The parts are treated as one service set rather than unrelated spare items.

Variant-specific identity

ABB 3HAC046686-003 is not a generic copy of ABB 3HAC046686-002: its documented RMU102 association separates the set used in the track-measurement context from the RMU101 set.

Traceable battery path

Both records preserve a battery-backed measurement function, but the complete ABB model string, installed system context and board reference must remain attached to the enquiry and service record.

Questions & Answers

How do I choose between ABB 3HAC046686-002 and ABB 3HAC046686-003 for an SMB replacement?

Use ABB 3HAC046686-002 when the installed measurement chain is the RMU101/IRB context recorded for that set. Use ABB 3HAC046686-003 when the installed record is the RMU102/IRBT context. Match the board family before removing the old unit.

What must be recorded before ordering ABB 3HAC046686-002?

Record the robot family, the existing RMU101 board reference, the battery and cable references, and the installed SMB position. That evidence keeps ABB 3HAC046686-002 separate from the RMU102 set ABB 3HAC046686-003.

Can the RMU102 board from ABB 3HAC046686-003 be substituted for ABB 3HAC046686-002?

No substitution is stated here. ABB 3HAC046686-002 is documented with RMU101 3HAC044168-001, while ABB 3HAC046686-003 is documented with RMU102 3HAC043904-001; retain the board family shown on the installed record.

What should be checked if the robot loses its stored axis position after fitting ABB 3HAC046686-002?

Check the battery connection, SMB connectors and axis labelling for ABB 3HAC046686-002, then verify the stored revolution record before changing calibration values. A connector mix-up can look like a position error.

Why does the transport record matter for ABB 3HAC046686-002?

The product record for ABB 3HAC046686-002 identifies a lithium-battery dangerous-goods entry, UN3091 class 9. Confirm the shipping route and paperwork before dispatch; do not apply that transport classification to ABB 3HAC046686-003 without its own record.

How can a service team keep ABB 3HAC046686-003 from being confused with a similar SMB set?

Keep the complete ABB 3HAC046686-003 model string with the RMU102 board reference, robot/track context and requested quantity. Do not identify the set by the enclosure appearance alone.
