Have an eight year old YK with optiview panel. Machine needed bearing replacement. When power was re-energized, panel had lost it's setpoints. Reloaded setpoints but couldn't set time and date. Book says time and date function along with setpoint data, history, etc are loaded on the BRAM chip. Ordered BRAM chip and installed same. Used procedure outlined in manual to load info on blank chip. No dice. Machine runs but still has Alzheimers.
I'm clueless. Anybody else got one?
