Hi, I started working on a KR5 that hadn't been used in a while and I came up with the following controller load sceen message.
"Harddisk 1 : KUKA_KRC_30GB
System COnfiguration Data updated
ERROR
0271: Check date and time settings
WARNING
0251: System CMOS checksum bad - Default configuration used"
I assumed it was the CMOS battery that was bad, but I'm not certain. I tried finding a replacement battery, but I wasn't able to.
