Buffer Battery
Note
If the battery was exchanged although the Gold cap was not loaded sufficiently, the battery-
buffered areas of the working memory are deleted. The non-volatile PLC markers and words
belong to this area. This may mean that some components of the machine have to be set
again (tool changer, swivel head, etc.) --> Ask the machine manufacturer!
The datum and the time of the BIOS setting were losts. Set these values again --> see
"Setting the System Time" on page 15 – 237.
