Hello, Please refer attached sheet. In PCU 50.3, 2 nos. batteries will be there, one for PCU BIOS & second one for MCI board. MCI board battery is NCK battery i.e. it backs up NC, PLC data stored in SRAM. So you need to replace battery which is connected to MCI board. HTH P. S. - In order to share with you battery article number, please attach ths snap shot of PCU50.3 here. {Article number which you specified doesnot exist, so its better if you attach the snap shot of PCU50.3 nameplate sticker.} AttachmentNCK MCI board battery.pdf (549 Downloads) |

Hello Please open the attachment. As per the instructions i opened the cover and it seems like the same battery on top is connected to the MCI PCB. Not directly, but connector from the MCI board and connector from battery is close to each other on anotber PCB just below the battery.. No other battery is visible nearby and no battery on MCI PCB.

Hello, Please refer attached files, explaining how to take & reload series data back up. Please note, you need to re-connect new battery within 10 minutes (time depends on energy stored in super capacitor inside PCU which proiveds power to SRAM) from the time you disconnect NCU battery. HTH P. S. - Ofcourse you need to replace battery when power to Machine & PCU is OFF/shutdown. AttachmentHow to reload series start up files using OP.zip (549 Downloads) |
