Hi,
I am working with 3 different IGM robots that run the K4 controllers. At random times I am seeing portions of the display on the pendant black or blank out. Robots all still function, it just makes navigating hard. Along with that it makes me uneasy as to what may happen next. So far we have tried: new pendants, new cables, reseated all connections, check voltages on power supplies.
Originally I thought it was related to heat in the cabinets but have made sure that is not the issue. Once the screen does blank out or lose image sections we will shut down the machines. If we don't wait approximately 30 minutes before trying to turn them back on we cannot boot past "6" on the motherboard.
This is a real brain buster I am hoping someone has some ideas or experience with this issue. See attached pictures for images of the pendant lcd.
Thanks
Adam
