6.8 Replacing the Encoder Battery
The data stored by the encoders is protected by a 3.6 V lithium backup battery located in
the base of the robot.
Battery Replacement Time Periods
If the robot is kept in storage and not in production, or the robot is turned off (no 24 VDC
supply) most of the time, then the battery should be replaced every 5 years.
NOTE: Dispose of the battery according to all local and national
environmental regulations regarding electronic components.
If the robot is turned on with 24 VDC supplied to the robot more than half the time, then
you can increase the replacement interval to a maximum of 10 years.
Battery Replacement Procedure
1. Obtain the replacement battery.
2. Switch off the SmartController.
3. Switch off the 24 VDC input supply to the robot.
4. Switch off the 200/240 VAC input supply to the robot.
5. Disconnect the 24 VDC supply cable from the robot +24 VDC input connector. See
Figure 3-3 on page 40 for locations of connectors.
6. Disconnect the 200/240 VAC supply cable from the robot AC input connector.
7. Using a 5 mm Allen wrench, carefully unscrew the AIB chassis securing screw.
See Figure 6-2 on page 74 . Note that the screw does not need to be completely
removed in order to remove the chassis, as this screw is captured on the chassis
heat sink.
8. While holding the chassis heat sink, carefully and slowly lower the chassis down
(see Figure 6-3 on page 75 ), so there is access to the battery. See Figure 6-7 .
CAUTION: Replace the battery only with 3.6 V, 8.5 Ah
lithium battery, Adept part number: 02704-000. Battery
information is located in the base of the robot.
