More Information

Overview Manuals Battery Interface Alarm Response Service Control Product Applications

Features:

  • RMU101 identity: ABB names the exact spare as the serial measurement board
  • Three-pole interface: the board is paired with battery 3HAC044075-001
  • Position-data service: battery work concludes with revolution-counter updating
3HAC044168-001 belongs to the robot measurement chain rather than the controller computer or fieldbus system.

Its three-pole battery arrangement is a hard selection boundary because ABB warns users not to replace or convert the contact.

The board's service value depends on clean ESD-safe handling and a controlled battery-change procedure that protects synchronization data.
Apter Power can review 3HAC044168-001 board markings, connector type, physical condition, battery requirement, and official maintenance evidence.

  • Connector: the RMU101 uses a three-pole battery contact
  • Battery: ABB specifies 3HAC044075-001
  • SMB assembly: the documented host unit is 3HAC046277-001
  • Contact rule: do not replace or convert the battery contact
  • Alert: event 38213 reports low battery charge
  • Data protection: keep controller power on until replacement where practical
  • Typical interval: a new three-pole battery is documented at about 36 months
  • Extended shutdown: use ABB's battery shutdown routine when applicable
  • ESD: handle the board and connectors with electrostatic precautions
  • Cleanliness: remove metal residue before opening the SMB enclosure
  • Closure: replace the removed cover gasket with a new one
  • Recovery: update revolution counters after the battery procedure
  • Robot position backup: support battery-backed resolver revolution records
  • RMU101 maintenance: match the three-pole board, battery, and SMB unit
  • Low-battery recovery: respond to alarm 38213 without losing synchronization
  • Measurement-board sourcing: verify markings, connector condition, and ESD-safe packing
Description
3HAC044168-001 is ABB's RMU101 serial measurement board, identified in the official battery procedure by its three-pole battery contact. ABB links the exact spare to multiple robot platforms, including IRB 1600, IRB 360, IRB 460, and IRB 7600.

The battery-backed position record associated with 3HAC044168-001 helps retain resolver revolution information while main power is unavailable. ABB documents a typical 36-month life for a new three-pole battery and issues alarm 38213 when battery charge is low.

Service planning for 3HAC044168-001 should confirm the installed SMB identity, three-pole connector, approved battery 3HAC044075-001, ESD controls, clean enclosure condition, and revolution-counter procedure. Do not convert the battery-contact arrangement during maintenance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which battery is specified for the three-pole contact on 3HAC044168-001?
Use ABB battery unit 3HAC044075-001 with SMB unit 3HAC046277-001 containing the RMU101 board. Do not substitute the two-pole battery arrangement.
What does alarm 38213 indicate for a robot using 3HAC044168-001?
It is the ABB battery-charge-low alert. Plan the battery change while preserving synchronization and follow the applicable controller procedure.
Why should controller power remain on until work starts on 3HAC044168-001?
ABB recommends keeping power on until battery replacement to reduce the risk of an unsynchronized robot and loss of retained position information.
Which contamination risk must be controlled before exposing 3HAC044168-001?
Clean metal residue from the cover before opening it. Conductive debris can short the board and create hazardous failures.
What must be completed after battery service around 3HAC044168-001?
Install a new cover gasket, close the base correctly, and update the robot revolution counters using ABB's controller procedure.
What should a buyer submit when requesting 3HAC044168-001?
Provide clear board and connector photos, the robot model and serial number, SMB unit identity, battery contact type, alarm record, quantity, destination, and required delivery date.
