Battery Replacement
The memory equipped on the X8GC printed board of the robot controller is backed
up by a lithium battery to save the data. Replace the battery every five (5) years.
The lithium battery will turn its life when used for a predetermined time. If it is used,
neglecting the life, the battery voltage will drop to below the voltage required for
keeping the memory data, resulting in the data being lost and faults caused by
leakage of the battery liquid.
If the following alarm has occurred, replace the battery with a new one.
