She then called back indicating that it had been repaired. The gate was down from 1310 to 1340 8/16. 08/15/96 07:42 dlwarf Connected slide gate PLC to the Pittag room voice line. Answering machine will be out of service until 8/20/96. 07/17/96 08:33 dlwarf Ajusted PLC timer for slide gate failure alarm to prevent false alarms. General maintenance check found no problems. Ran sticks on separator coils with these results: Coil 00 detected 10 out of 10 sticks. Coil 02 detected 9 out of 10 sticks. Coil 04 detected 10 out of 10 sticks. Coil 06 detected 10 out of 10 sticks. Coil 08 detected 10 out of 10 sticks. Coil 0A detected 10 out of 10 sticks. Coil 0C detected 10 out of 10 sticks. Coil 0E detected 10 out of 10 sticks. 07/12/96 09:41 scottl Installed strobe lights for the slide gate alarm system and modified PLC program to accommodate for this. Replaced all the air line for the A-side pnuematics and replaced relief valve to eliminate chirping during exhausting. Replaced the backplane in controller 52 due to low efficiencies and to improve timer tag detection. An oiler system is going to be installed on the slide gate pneumatics by the Corp personnel when it arrives. This could improve overall performance and longevity of the entire pneumatic contol system. 07/08/96 16:44 scottl Lisa (assistant biologist) at this facility called on 7/5 about several gate alarms on the A side that occured over a two day period. During all instances the alarm was reset on the A side and operations continued. PSMFC personnel travled to the site to test the functionality of the gate Initially it was thought that the air cylinder was failing and may need replaced. Futher troubleshooting found that the cylinder is probably not the culprit but is not being discounted. The relief valve seems more likely to be a major contributing factor for erratic gate behavior. One solution to this failing relief valve is to go to a different type, such as a needle valve rather that a rubber diaphram type. Also, the PLC program implements scaling factors with use in the Anti-slam portion of the program that need to be adjusted with changes in gate speed. Bill Spurgeon is aware of all this and assigned a maintenence mechanic to be present while This problem was being diagnosed. The slide gate is functioning fine at this time and PSMFC will coordinate with the C.O.E to resolve it. Aslo, the facility is in 100 percent sample. Therefore the A raceway flume dewatered and the timer tags are not firing due to this. 07/04/96 05:09 scottl Thie old efficiency report showed that controller 56 was locked up again. Replaced entire controller, tested good. 07/01/96 16:17 scottl Visited site for general maintenence check. Stick tested seperator monitors results are below. A-seperator coil 00 detected 10 of 10 stick tags. coil 02 10 of 10 coil 04 8 of 10 coil 06 9 of 10 B-Seperator coil 08 detected 10 of 10 stick tags. coil 0A 10 of 10 coil 0C 10 of 10 coil 0E 10 of 10 Found controller 56 locked up. This controller is associated with and B diversion coils 28 2a A diversion coils 20 22 A-raceway coils 34,36 Last time stamp indicated that the controller went down at approx. 0430hrs cycled power on controller to correct, will monitor for re-occurring problem. The Sub-sample rate is at 100 percent. 06/24/96 16:22 dlwarf Completed installation of slide gate failure alarms. Worked with site personnel on operating procedures. 06/20/96 16:18 scottl Finished installation of the Slide gate alarm system. This feature is now operational. Removed all exciter covers to help dissipate heat during the summer months. Covers will restored when appropriate. Stick tested A and B seperator,Below are the results. A-separator 00 detected 10 of 10 sticks. 02 detected 10 of 10 04 detected 6 of 10 06 detected 7 of 10 B-seperator 08 detected 10 of 10 0A detected 10 of 10 0C detected 10 of 10 0E detected 10 of 10 06/17/96 21:43 scottl This is a correction for the entry made on 6/14/96. The facility is NOT in 100 percent sample. The sample rate today is 16.6 percent. The diversion gates are diverting at all times. 06/14/96 15:26 scottl Installed limit switches and completed wiring for the diversion gate alarm system today. Testing will begin the first of next week around 6/18/96. Also the sample gate over ride switches were thrown at 0700 this morning. The facility is in 100 percent sample and is diverting during sample. Repaired the exhaust valve on the A-separator control system. tested good. 06/12/96 16:33 scottl Started the installation of the Slide gate failure alarm for both A and B seperator gates. This alarm system will be a proto-type for evaluation purposes and should be functional by 6/14/96. The A side slide gate has a bad soft close exaust valve and will be replaced on 6/14/96. We also noticed that the air cylinder for this gate could be failing and need replaced in the near future. PSMFC will notify Bill Spurgeon (corp site biologist) of this problem and assist in any way to resolve it. Found bad connections in the exciter for coils 04,06 A-seperator gate Repaired connections and ran stick test. Results are as follows. A-seperator gate, coil 00 detected 20 of 20 sticks. coil 02 detected 20 of 20 coil 04 detected 17 of 20 coil 06 detected 20 of 20 B-seperator gate, coil 08 detected 16 of 16 sticks coil 0A detected 16 of 16 coil 0C detected 15 of 16 coil 0E detected 15 of 16 There were no other problems found. 06/04/96 15:53 dlwarf Review of efficiency reports show no problems at site. 06/03/96 21:16 scottl The old efficiency report showed degredation in the diversion efficiency on B-seperator gate monitor. Approx. 25 of 60 fish where sent to the raceway. Corp personell reported a loud sqweek on both gates. A physical inspection found that the soft close valve was presumed to have dirt or rust in it causing improper exausting. Cleaned valves with WD-40 and lubricated valve bodies and manifolds on A and B seperators. Ran stick tests with 100 percent diversion efficiency on both monitors. Also there was some contamination visible in the air lines. Future maintenence may require a complete decon of the entire pneumatic contols. 06/03/96 07:44 scottl Lisa (assistant Biologist) called sunday 6/2 @ 4pm to say that the gates are very squeeky and should be looked at. Corp maint. people looked at them but did not take any action that I am aware of. Will follow up and check gate for mechanical failure. 05/21/96 08:02 scottl Repaired loose coil return wire in exciter for coil 20, A-diversion. tested good. Also tightend slide gate cylinder shaft to yoke on both slide gates. Stick tested seperators at 100 percent efficiency on all four coils. Changed data disks on collection computers. 05/19/96 08:48 scottl This entry is for work done on 5/18/96. Met with Corps maintenence personnel. Lock Tight was applied to the slide gate air cylinder threads where it meets the yoke and tightend down. A cotter pin was missing on the A side yoke. A very bad thing. Corrected and tested gates. Replaced exciter pcb for B-diversion, coil 28. Replaced exciter pcb for A-diversion coil 20. Overall maintenence check found no other problems. 05/16/96 14:50 dlwarf Found the A side slide gate air cylinder disconnected from the gate. Threaded the air cylinder ram back onto the yolk to resume operation by 10:20am. All the A side pittagged fish were lost to the raceway while the gate was down. Site personel along with C.O.E. upper management decided to return the fish collected from the A side from 9:00pm on 5/15/96 to 10:40am today back to the river. 05/15/96 10:44 dlwarf This entry is for work done on 5/14/96. Found main computer locked up. Rebooted with no errors. Jen uploaded missing files from the backup computer. Did a general maintenance check. Everything checks ok. Ran a stick test on the separator coils with over 95 percent efficiency. 05/14/96 09:45 jen manually downloaded julian date 134 files from site and they are now being loaded into ptagis. 05/14/96 09:00 jen downloading data for 5/13/96 failed last night. maintenance crew is at site and working on machine. shortly the data will be downloaded and the database will be updated. 05/09/96 14:40 dlwarf Visited for a general maintenance check. Everything looks ok. Site personnel report that the diversion head boxes will now be kept at a much lower level. This will minimize fish holding up in the boxes. 05/01/96 21:47 scottl Replaced controller 55. Controller installed has new back plane. Checked all connections related to controller and coils. no-sub-sample rate to report. 04/30/96 16:09 scottl Forgot to add that the new monitor program Ver. 3.2 was loaded on the back up computer and is set to auto sync every hour. 04/30/96 16:04 scottl Controller 55 was locked up causing low efficiency for coils 44, 46 (diversion exit) 18, 1A (B-raceway) 28, 2A B-diversion. reseated all cards and tested ok. Will monitor controller for a few day's to ensure proper operation. 04/25/96 20:05 dlwarf Visited for a maintenance check. Ran sticks on separator coils with over 90 percent efficiency on all coils. 04/12/96 13:00 carters Stick tested A-separator at 85 percent efficiency. This was after coils A4 & A6 were re-tuned. We're watching water velocities and levels at LoMo and will return on 4/15 to re-check. 04/09/96 16:00 carters Livingston reports Corps sub-sample rate is 25 04/04/96 8:45 carters Site has been pre-season tuned and tested. 03/29/96 16:00 carters Site is partially tuned.
