**08:40 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675625098379):** are the recycled water pumps run from an ML?
**08:40 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675634802029):** yes
**08:40 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675651842129):** what's the problem
**08:44 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675843381839):** they are saying this system was never tested during the cut over. they should be able to swap the pumps from pressure control to flow control
**08:44 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675875744599):** depending on wether its going to distribution or not
**08:44 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675886603059):** i think its distribution or the pond?
**08:44 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675891850349):** yes
**08:45 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675905666539):** there is a "dedicated" pump to pump to the reservoir
**08:45 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675908225179):** its always on pressure control. they dont have flow control
**08:45 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675918902499):** interesting. ok
**08:45 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675923381539):** just one of the 3?
**08:45 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675927204779):** that pump should be on flow control
**08:45 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675930615269):** yes
**08:45 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773675940147209):** the other two are pressure control to distribution
**08:45 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773675945325469):** that pump may be down ,they have one down pump
**08:46 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676000062789):** there is a way to select the function of each pump
**08:47 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676026759179):** i think the problem is that selector isnt working
**08:47 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676032200839):** likely
**08:47 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676066943009):** they can't change it on old scada?
**08:48 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676091553069):** i would think they would have tried.
**08:49 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676141027209):** old scada might not work for those because the IP and network changed
**08:51 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676318253359):** is that ML on ethernet?
**08:52 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676324296839):** yes
**08:58 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676731560859):** takes me so long to find things in aveva still.
**09:00 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676808360579):** detail it so you can ref it later?
**09:00 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676858330019):** not exactly that easy. but i'll take all the notes i can
**09:01 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676892850319):** just trying to find the page that the toggle is on so i can start the process of finding which tag its linked to
**09:01 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773676908455999):** search isnt helping.
**09:02 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676924525439):** I wonder if you take a screen recording if you can feed that to AI and get a decent outline
**09:02 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773676947798789):** I know I can feed youtube videos to gemini and it will give me a great outline
**09:03 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677005429369):** i found the tag in the PLC. that might help
**09:03 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677009022699):** its definately still in PSI mode
**09:03 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677026377729):** I wrote that program btw
**09:04 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677045869689):** oh yeah?
**09:05 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677104339269):** designed the whole thing actually. they had an old control system that modulated electric valves to control flow. it was a mess. so I suggested the piping change and new control logic
**09:05 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677153597479):** nice! i may ask you questions then
**09:06 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677168052969):** they just swapped to P1 and it is running in distribution mode i think
**09:06 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677180422779):** i mean RES
**09:06 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677184279089):**

**09:06 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677192059869):** P1 Call to RES
**09:06 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677199623069):** so should that pump be on flow control?
**09:06 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677216051029):** should be. I would verify
**09:09 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677371207809):** i just called them.'
**09:09 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677381393229):** They have an electrictian out working on something
**09:09 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677391864719):** they swapep back to P1, which seems to be working fine on flow control
**09:10 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677416554459):** i wont be able to test the other pumps until hes done
**09:10 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677444526079):** so hes going to call me again later today.. but i have the SSLOCSD meeting and the reno meeting.. but i told him about it.. its derik, one of the operators
**09:11 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677492566849):** alright. this is not a super critical function of the plant. they can run things manually if they need to
**09:11 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677505809869):** copy
**09:12 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677528425319):** lazy operators like derik will think otherwise
**09:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677604082779):** yeah.. i mean it should all work, but no need for a sunday call and a first thing monday morning call.
**09:14 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773677688908429):** was it Derik that called yesterday?
**09:16 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773677807633449):** no, i think a different operator called yesterday
**09:29 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678594785459):**
![[F0ALUMNPRGE_image.png]]
**09:30 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678601469959):** ok theyre back on pump 3
**09:30 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678610585989):** it has the P3_ call to res bit active
**09:30 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678619518009):** but flow control doesnt seem to be working
**09:30 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678622169509):** still digging
**09:33 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678810717349):**
![[F0ALWQEHAUA_image.png]]
**09:33 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773678833188519):** both res and dist seem to be copying the same speed source
**09:43 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773679396613359):** i think this is the problem, but this would mean that its always been like this
**10:00 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773680438710049):** interesting
**10:01 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773680472175139):** it would seem crazy that we never tested it or used it since I created it, but it's possible!
**12:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773688410809679):**
![[F0ALW0JSJDU_image.png]]
**12:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773688423137399):** is there another PID that calculates the flow rate setpoint based on pond level?
**12:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773688426021619):** or tank level
**14:27 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773696432817319):** oh yes! I forgot about that. the flow setpoint increases as the tank level rises
**14:27 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1773696458083949):** sorry to leave you hanging for two hours
**16:45 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1773704702061579):** It's ok. They are ok. I’m just gonna go out there on Thursday for this. It will be a lot easier. I have lots of other questions for them and I can't access old scada from this system for some reason
