Date Time Who What ---------- ----- -------- ----------------------------------------------- 12/30/2004 08:55 troy@ree 02:LowExcCurrent: Noted 12/28/2004 16:14 Scott_Li The retro fitting of the back panels with additional support structure has been completed. This was done to reduce the amount of vibration induced into the PIT tag antennas when the flow through the viewing window is increased. Talked with Mark Johnston this afternoon and he indicated that BOR or YIN personnel will indeed be responsible for cleaning the trash racks on a regular or as needed basis. On this same note, the racks were cleaned sometime yesterday afternoon. This was reflected in the status reports for antenna 02, the antenna that is most effected by increased flow and turbulence. FYI.. Talked with the YIN at the juvenile facility about projected water up date for the JFF. They indicate that water up and sampling will be delayed until the end of January due to electrical problems at the Rosa irrigation station. PTAGIS will be onsite early January to reconnect the FO transmit line on each of the juvenile transceivers and consider the site in "full production mode". 12/27/2004 16:24 Scott_Li Efforts are under way to install additional support to the backside of the barrier plates on the up and down stream side of antennas 02 and 01. This is being done in order to try and reduce vibration due to turbulent flow through the fish viewing window. The turbulence is caused by too much debris and mil foil weed accumulating in the trash racks therefore increasing the amount of flow through the antennas. Mark Johnston of YIN is aware of the situation and has made an effort to inform the BOR that the trash racks need to be cleaned on a regular basis, but it appears that this isn't being done. Although efforts are being made to reduce vibration and mitigate noise picked up by the transceivers,but again the trash racks will have to be maintained on regular basis. FYI.. The main reason for antenna 02's elevated noise levels are primarily due to clogged trash racks. Notes are being taken that will point out problems with the initial design of the left bank ladder PIT tag installation so that improvements can incorporated into the center and right bank design. PSMFC will be back onsite tomorrow 12/28 to complete modifications. 12/25/2004 11:01 scottl Due to excessive noise alarms on antenna 01, the noise percent threshold will be adjusted to a higher level until the source of interference can be eliminated. This issue will adressed on Monday, Dec 27th. 12/21/2004 14:58 Scott_Li Mike Berger from the YIN will be onsite at the left bank ladder to dewater the system Monday at 9:30 am. PSMFC will then fabricate and install additional bracing in order to mitigate the vibration on the antenna support structure. The ladder will potentially be dewatered for 1.5 day's. PSMFC will attempt to complete all in ladder work by the end of the day December 27th. The trash racks will also be cleaned at this time by YIN personnel. 12/21/2004 09:39 Scott_Li It was noticed that transceiver 02 has erroneous characters in the raw data file. These characters only appear in the line that specifies the Firmware version. See below. Version: FS1001A 3.±± This problem has been consistent for at least the last 5 day’s and is at this point unclear as to when the problem started and why. More investigation into this will be conducted later this week. First inclination is that the transceiver may be the culprit and not the radio transmission but this has not been verified. This problem has not been detected the data files for transceiver 01. 12/17/2004 08:23 alan@ruf 02:LowExcCurrent,02:TestTagFailure: This transceiver has gotten noisy due to the barrier plate vibration. Repairs are in progress. 12/14/2004 08:54 Scott_Li Informed Mark Johnston of the vibration issue that was discovered yesterday and offered Mark Recommendations on how to fix the problem. Mark to source some additional Fibergrate material and procure, PSMFC offered to install the additional backing to the barrier plates when the material is available. Maint. Personnel will be onsite Thursday 12/16 to remedy the situation the best we can until a permanent fix can be implemented. 12/13/2004 14:02 Scott_Li Visited the Left bank ladder in order to track down the source of interference detected on Antenna 02 and minor interference on antenna 01, it was discovered that the barrier plates located up and down stream of antenna 01 and 02 were vibrating causing noise to be introduced into the transceiver. Previously this was not a problem, but due to high water conditions and the accumulation of debris in the trash racks have drastically changed the hydraulics through system therefore introducing severe turbulence around antenna 02 especially. This problem should be fairly easy to remedy by adding more material or some ribbing on the back side of the barrier plates , Beaf them up abit.. PSMFC will inform Mark Johnston of the situation and help facilitate the modifications that are necessary. 12/13/2004 09:10 Scott_Li The raw data files indicate that transceiver 01 and 02 were in excessive noise conditions for ~ 7 hrs on 12/12 between the times of 0900 and 1600 hrs. Some of the cause could attributed to detuning due to temperature. On Friday 12/10, it was noticed during a site visit that Coil 02 had periodic noise spikes that could not be explained. Swapped antenna cables to isolate the problem and the interference followed the antenna and cable, not the transceiver. Will be on site today to further diagnose the problem. Also files will downloaded from the redundant laptop computer for file size comparison with the production computer files. This test will be ongoing until complete confidence of the radio modems performance is achieved. 12/11/2004 08:11 troy@ruf 01:LowExcCurrent,02:LowExcCurrent: These alarms were caused by PTOC personnel while performing a GMC. 12/10/2004 16:33 Scott_Li FYI.. some of the data files , inparticular file PRO04344.E1 contains various error messages directly relating to the reconfiguration of the radio modems by PTAGIS personnel and therefore should be ignored. This erroneous data is not a caused by the radio transmission failing or in arrears. A complete report will be compiled on Monday, Dec. 13th and will be posted to the Event forum for the Prosser dam Project for archiving. In short, the radio data transmissions are performing very well as indicated by the diagnostic tests that were conducted this afternoon. 11/30/2004 10:05 Scott_Li The antenna flow travelers and the LCR sweep data for both antennas 01 and 02 was uploaded to the PRO workspace under the documentation forum. 11/24/2004 09:28 Darren_C PSMFC was on site yesterday to adjust the test that is being performed on the radio gear currently in use for the communications to the ladder transceivers. The transmit side of the fiber communications to the Juvenile transceivers was removed to ensure that file sizes between the Platform and the test laptop are equal. The buffers were cleared on the Juvenile transceivers so that if the Juvenile facility is placed into collection prior to the completion of the radio test we will have buffered data to submit. This radio test is scheduled to last for one (1) month and started at 14:00 hrs. Darren R. Chase PSMFC Systems Engineer (509) 735-2773 ext.3 11/23/2004 11:19 Troy Coils 01 and 02 were tuned. Noted that the water level in the window had dropped 2inches below the top of the window and some tracked lighting had been installed. Retrived files from the laptop stationed in the pit and files from PC2 for data comparison. No other problems noted. Placed 2 lifejackets in the locker at the Juvenile facility. 11/16/2004 15:09 scottl The installation of the Left bank ladder antennas along with radio communications from the ladder to the JFF has been completed. The radio signal strength is somewhat of concern in that the power levels may need external antenuation. We will be researching how to optimize the radio data stream. The ladder watered up on 11/16/04 at 11:00 and PIT-tag detection system is fully functional. Ran 65 stick tags through the antennas. The water flow through the counting window is somewhat slow so sticks do not travel through the system at optimal orientation. The unique mode is set to off on the readers so the hits per tag will need to be reviewed. More stick tests will be conducted later this week and will be much more extensive. An additional PC was installed in the ladder pit for data validation and full redunancy while the system is being evaluated. The production data collection platform is in operation and actively submitting files to PTAGIs and will remain this way indefinately. 11/09/2004 16:56 Dave Timer tags and associated coil_ids have been assigned to the ptagis3.test_tags table for PRO. 10/21/2004 12:11 scottl This is a test message from the 'legacy' web interface. It should be deposited in the top-level directory of the PRO events forum. ####End of Event Log for PRO###
