Hello Buttcnc, Please post your query in new topic instead of in old post. You will find New topic button at top of product conference which you can click to post new query. Also use search key button provided at top right side of page, in which you can type related texts of query so that you can get detail information/discussed topic in past immediately, e.g. if you have typed 840D 2001 alarm you will get list of FAQ/topics discussed in forum, please have a look here. Please confirm if you have faced any NCK battery related alarm/message before this problem. If your system is quite old, I suggest you to procure NCU battery so that during rectification of this problem you can replace it & again such problem will not be repeated. Please check if your system has PCU20 or PCU50, because to restore PLC data, both has two separate procedure. Moreover please confirm you have NC, PLC back up data on external storage device. Also please refer the topics already discussed & follow the procedure & clear PLC data. If you face any problem please come up with snap shot of 840D NCU box 7 segmant display, so that forum member could be able to help you more accurately. HTH. |
