| 1 | When the pump runs, the pump Motor + MOV runs together. Which does not follow the normal sequence. The ampere becomes high (800+) for the two to run together. | 4P01-D 4V09-D | OGR | There has also been a plant inside shutdown due to the high ampere. (Date 21.05.2022) Team ICE: |
| 2 | The wrong data of motor wending temperature shows in SCADA. Which is completely different from field data. | 4P01-D | OGR | It is very embarrassing during the operation. The problem has been pending for more than two years. Team ICE: |
| 3 | The wrong data of motor wending temperature shows in SCADA. Which is completely different from field data. | 4P01-C | OGR | It is very embarrassing during the operation. The problem has been pending for more than two years. Team ICE: |
| 4 | When the pump is stopped and normally shuts off, a fault automatically occurs in the MOV. In this case the valve is fully closed but the fault has to be reset from the field. | 4P01-E | OGR | The problem has been pending for more than 1 year. Team ICE: |
| 5 | When the pump is stopped and normally shuts off, a fault automatically occurs in the mov. In this case the valve is fully closed but the fault has to be reset from the field. | 4P01-F | OGR | The problem has been pending for more than 1 year. Team ICE: |
| 6 | The MOV between IRP-1 and OGR(A). There is a fault here. That is why MOV open cannot be closed through command from SCADA. | 4V01-A | OGR | Team ICE: |
| 7 | Analyzer’s pH meter reading does not match Scada reading. | AIT-4006 | OGR | 7.2 This data was fixed on SCADA when the minister arrived at the plant. Team ICE: |
| 8 | Sand filter ”E” LIT’s data miss matching. 1 meter difference of field reading is observed with scada reading. | LIT 2003-E | IRP-1 | When scada reading is 5.0 m the filed reading is 4.0 m Team ICE: |
| 9 | The back wash pump (2P01-A) cannot be controlled from SCADA due to lit problem. The operation has to be done locally. | LIT 2002-A | IRP-1 | The problem has been pending for more than 2 years. Team ICE: |
| 10 | Sludge pump ”2P03-A” shows two level stages at the same time. Such as HIHI and LOLO. For which it is not possible to operate this pump remotely. | 2005-A | IRP-1 | From Jan-2022 to till now. Team ICE: |
| 11 | During air blower operation, hz, amp etc. data is not seen in SCADA. | 2M01-A&B 3M01-A&B | IRP-1 IRP-2 | Graphs need to be added to scada for observation monitoring and reporting. Team ICE: |
| 12 | The SCADA room wall monitor(BIG SCREEN) cannot be turned off during shutdown. Nothing can be done on or off. Totally out of operation. | SCADA MONITOR | SCADA ROOM | In this case, there is a problem with server backup during shutdown. Team ICE: |
| 13 | Korean language is set as the main CC camera server operator language. English language needs to be set for proper operation. | Main CC Cam server | SCADA ROOM | From Apr-2019 to till now. Team ICE: |
| 14 | sand filter E MOV (3V05-E) not taking auto command. As a result, the operation has to be done locally and manual backwash has to be given. | 3V05-E | IRP-2 | From 18-Apr-2022 to till now. Team ICE: |
| 15 | Sludge pump ”3P03-A” shows two level stages at the same time. Such as HIHI and LOLO. For which it is not possible to operate this pump remotely. | 3005-A | IRP-2 | Local operations are being carried out from the field. Team ICE: |
| 16 | Chlorine weight scale calibration is required. Wrong value shows. No similarities are found between SCADA and field reading. | 5M07-B | IRP-1 | From 26-May-2021 to till now. Team ICE: |
| 17 | Chlorinator-2 needs to be recalibrated. Because much more gas passes in a short time than the set value is given here. | 5M01-B | IRP-1 | There have also been cases of 15-20 kg of gas being lost per hour despite the low set value. Team ICE: |
| 18 | DTW 223’s one-day running hour is not being added to the daily report page. | SCADA REPORT | DTW-223 | Team ICE: |
| 19 | In Scada, amp, hz does not change any data. There is nothing in the graph. | SCADA | DTW-112,217 | Team ICE: |
| 20 | Flow quantity does not change. One data is fixed. | SCADA | DTW-106, 120, 202, 208, 209, 213 | Team ICE: |
| 21 | There is no similarity between field flow reading and SCADA reading. Giving wrong readings in SCADA. | SCADA | DTW-106, 115, 117, 202, 203, 208, 205, 213 | Team ICE: |
| 22 | No communication is available at SCADA. Out of scada control. (SCADA Pac problems.) | SCADA | DTW-208 | Local operations are being carried out from the field. Team ICE: |
| 23 | Cannot be operated remotely despite having SCADA communication. The pump automatically turns on / off repeatedly in the remote position. | SCADA | DTW-103, 112, 122, 201, 217, | Local operations are being carried out from the field. Team ICE: |
| 24 | These palms suddenly took up more amperes of design while moving (100+ amp). As a result, regeneration and rehabilitation work had to be done at some of these pumps(104,211,202). | SCADA | DTW-104,202, 205,207,211 | Even after taking more amperes than the design, these pumps did not trip, did not stop. Why? The reason has to be searched. Maybe the automation didn’t work properly. Team ICE: |
| 25 | The UVR relay does not work properly. | SCADA | DTW-106,113, 117,118,119, 223 | Team ICE: |
| 26 | Physically the DTW-109’s generator is off but Scada is showing continuous running. | SCADA | DTW-109 | Team ICE: |
| 27 | Amp & Hz Fluctuate in auto/local in both mood | SCADA | DTW-205 | Now stop Team ICE: |
