4.6 Replacement/changing activities
4.6.1 Replacing the SMB battery pack
General
The SMB box contains a main board and a battery for the memory backup in order
to maintain position data.
SMB boxes manufactured after 2015 are equipped with a SMB board RMU101 (Ref.
3HAC044168-001) and a Battery pack RMU (Ref. 3HAC044075-001).
The battery should be replaced every three years or when the battery is going flat.
This is generally shown by an error code on the FlexPendant screen (38213).
Information about error codes can be found in the FlexPendant documentation.
Note
In a new system the batteries are charged to full capacity after a few hours in
STANDBY mode.
Location of SMB battery pack
The SMB battery pack is located in the SMB box. The box can be located either
under the track motion, or on the side of the carriage. The principle for how to
replace the battery is the same even if the location varies.
