Thursday, January 02, 2020, 10:10, David Wang, Crane, Standard Operation, , , TH crane issue.
|
Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control on N-S, E-W and up-down movements do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded the program. I guess the battery is drained out very fast for some reason. So, We face the same problem again this year.
Adam checked control room main power supply. I checked in TH crane again. The problem is still there. We can confirm this is the same issue like last year. |
