1) Turn the controller power ON once. (For approx. one minute.)
2) Turn OFF the power supply of the controller and remove the filter cover of the controller front. The battery
is in the filter cover. Place the filter cover on the installation surface so that it cannot be removed from the
front of the controller.
3) Pick and pull up the connector of the old battery and remove from battery holder.
4) Fix new batteries into the battery holder. As shown in
, fix the cables that come out of the battery so
that they are not trapped by the side of the filter.
5) Connect the connector of the new battery cable. Connect so that the red lead may become left-hand side.
Complete the work within 3 minutes after removing the old battery.
6) Make sure that the filter is not separated from the cover, and re-fix the filter cover on to the front of the
controller, fixing securely. When doing this take care not to trap the battery cable.
7) Refer to the separate manual "Detailed Explanation of Functions and Operations", and reset the battery
cumulative time over alarm.
[Caution] If the old battery is replaced because it has been used up, it is necessary to set the origin again. Refer
to the separate "Robot arm setup, basic operation, and maintenance" and reset the origin.
This completes the replacement of the controller battery.
