I removed a Yasnac MRC CPU chassis (c1) to replace a noisy fan (Alarm Code 7491). My boss had me swap chassises (sp?) from an identical controller (c2) because he thought fan replacement would take too long. Yeah, I know.
I installed c2 and the robot went about it's business. I replaced the fan and installed c1 into the other controller. I received a "LOAD BATCH CMOS FILES" message. After trying to load CMOS from FDE, the job was moved down the priority list. We returned to it some weeks later and the Teach Pendant text is in Japanese. I get a Japanese/English option in maintenance mode but that is all. I have not found this issue in any of our manuals.
Any assistance will be greatly appreciated.
