@aonomus this is a medical gas vacuum pump. They live-in equipment rooms, dirty, hot, but free of patients, general bacteria.

@@The_Biomed Ah so these are for recovering inhaled gasses?

@aonomus no, patient suction.

Sure thing, what's the question and what device are we talking about

@The_Biomed it's an old machine with a model marking R88S-1. It's an old amsco machine that I can't find any door gasket for. Measures 16x16, but when I install the 16x16 gasket it is way too much slack remaining. The question I have though is replacing the high low valve kit, how to set the two temperatures on the dial.

@msramya446 its a luer connection. Comes in multiple colors and has a metal ring on the end. If you google it,www.medtronic.com/content/dam/medtronic-wide/public/united-states/products/patient-monitoring/microstream-advance-luer-ordering-information-sheet.pdf

Thank you for your reply Brother, I am from India,I am asking about the T price connector and End of T piece connection one metal ring valve is there ,what is the pressure setting .? How much pressure we have to give from cylinder?

Yes, there could be some debris. You could pull 5he cover and move the front section off the board. Examine the contacts. If it is still giving you those codes, look for damage, remove and reseat all connections. After that, try a calibration. If you're still hitting those errors, you'll have to find a repair company

Ok, well, 197 is stuck mono 2 coag. So try starting the unit with no pedals nor accessories plugged In. Hopefully 81 is just piggybacking on the 197 error.

one day, i'll work on that one...can't hold the camera and do the work, but i'll see what I can do

How long has the monitor been on? Takes about 10 minutes before it's ready

I've kept this on for more than 30 minutes. On my channel, I uploaded the calibration of the Escaio module. Thank you.

well the menu isn't going to just show up. have you checked your configuration to make sure you have AA and CO2? and selected FMG with the functions you have?

@@The_Biomed I'll check it tomorrow and let you know. I hope you can keep helping me. Thank you.

@EmmanuelOnigbo-m8p oh. When you say blank, do you see the table for the functions but no data, or a totally black display? Are the backlights working?

1st step would be to determine if the readings are accurate bc that temp and pressure are not inline with each other. If the temp is accurate then you either have a pressure leak or need a calibration. That's where I would go 1st. Verify and calibrate

@ thanks very much for getting back to me. I was thinking the air jet was leaking, not allowing it to build pressure. My problem is that I don’t have the tools to properly test the pressure and temperature. (And that means I can’t properly diagnose the machine). if the air jet isn’t the issue I will have to trash the machine. It gets to the point of not being worth the cost of repair. What a shame. Thanks again.

@Samlol23_drrich the air jet is supposed to leak. It's how the steam circulates in the chamber. But the safety release valve shouldnt...if you overfill the rez so the safety release is half covered, you'll be able to see if it's leaking, same for the air outlet valve. There's probably a biomed company near you with a test kit than can trouble shoot it for you

@ truly appreciate all of your expertise. The reason plumbers and electricians are required to do apprenticeships is for exactly what I learned from your reply. Would have never thought to test the safety release for leaks by overfilling the reservoir. (Maybe that’s what my staff is doing every friggin time they fill it). Something I did fixed it. Even though I bought a new air jet, after I installed it the machine had the same symptoms, and the new jet was leaking much more than I thought it should. I know the machine like the back of my hand. How much steam comes out of that jet and the new one just didn’t look right. I ordered a second new one but figured I would replace the entire relief valve assembly, so I bought the entire thing. As I said in the prior post, while waiting for the 2nd day delivery, I brought the machine home and took it apart just in case there was a leak from one of the solenoids. I took all four apart, cleaned the copper seats and ran a carb cleaner brush through all the orafices, then pulled the temp sensor and cleaned it (gently), pulled every wiring harness and sprayed contact cleaner on both ends then put it all back together this morning with the new part that was delivered late yesterday. Just ran a cycle and it worked perfectly. So something I did fixed it. Once again, thanks for getting back to me and sharing your expertise. It’s something most won’t do (see my video on the lack of support from Hayward when my pool heater had an issue. Once they found out I was a consumer they wouldn’t help me). Thanks again! Rich in NY

It was suggested there may be a cold solder joint on either the pots, or the larger connector on the back. I have yet to look into that.

@@The_Biomed thanks I do a lot of board repair so I was curious thanks.

@johnm4962 if you come across an adjunc 3 pcb with a similar issue, let me know about the cold solder joint scenario

@@The_Biomed yeah I don’t come across these boards often and my machine doesn’t have this fault.

You could send me a bad board and I could go over it ?

@@Burger-s8z what do you mean

there is no voltage to a steam trap, it's a purely mechanical, temperature controlled device

from what i've seen, just power cycle. if it continues, you may have a pcb issue

​@The_Biomed Yes there is a short circuit in the circuit but I could not detect what the harmonic element is

@FundsClinic afraid not. Could probably find someone on the bmet/biomed reddit groups, or thru dotmed. Actually tuttnauer keeps a listing of every company they have trained. So tuttnauer would be the best resource to finding a company that is knowledgeable and authorized to work on them

@kevinfrancis4513 this is the century v116. The 3000 series has individual valves, no manifolds

I got one of these coming up to work on..

Ok, think I saw individual valves but somehow they tore off the serial plate and name plate to identify the model. Let's see how it goes, thanks bro.

no, i skipped those steps on purpose. I need a better set up to complete those steps. Once I have it I can share it.

Can you help me calibrate the devices? Can I have your WhatsApp?

@daisizhou been awhile but yes. Had that unit at several biomed shops I've worked in

@@The_Biomed Can you get the service manual for 454a? I have been looking for it for a long time but have not been able to find it.

I have been unable to locate a service manual for that unit. If I ever come across one I'll let you know and try to share it on #medwrench

@jasonberube3186 I'm using an old bio-tek nibp monitor tester(that's the only model I can find written on it) it doesn't go to the upper values so I'm still trying to get this employer to buy the right one. Then it's just some hoses and connectors.

Oh ok. What’s the new make and model you trying to get. I just need to get something for the air source.

​@@jasonberube3186​ I was looking at the contec ms200, but after double checking, it only goes up to 400mmhg. I can't find one that goes up high enough. Just have to do a manual pump

@@The_BiomedI found something from fluke it’s the 3130 portable pressure generator it will definitely create the pressure required to cal the ATS

@jasonberube3186 wow, that's like an infusion tester and at $8-10k geez

so the entire pm procedure starts with the normal visual inspection, 1: look for any damage, 2: do electrical safety tests(leakage is really a waste of time), 3: check the calibration, calibrate if necessary. 4: leak test( attach a large cuff, set the pressure to 475mmHg, place it into standby; Press the ON/STANDBY button until the alarm message “CUFF” “NOT” “DEFL” appears. Release the ON/STANDBY button and within 5 seconds of the alarm discontinuing, press and hold the ON/STANDBY button again. The button must be held in for an additional 10 seconds before the unit will be set to STANDBY. wait 10 minutes, then turn it back on then press alarm silence and next press Pressure. the display should read 400mmHg minimum. I don't think you can do 2 at once, but i could be wrong. I'll test this out next time an ATS 3000 comes by my bench. 5: pull the battery, pull battery cables, check battery voltage(12v minimum) plug the unit in and check battery voltage while attached, should be higher than 12 volts. that's it

@@Ronnock actually I invented it when I was just an unfertilized egg. Also, this is for people already in the field, pretending to do the job and just slapping stickers. There are a lot of them

Yeah, I get that. I don't like those who just "lick and stick," but I maintain one should extend an olive branch to those who are too scared to admit they don't know.​@@The_Biomed

@@Ronnock agreed

Most likely, your safety release valve is compromised. I have a video showing the internals. Replace it and remember to test it during heatup once a week

@@The_Biomed Thank you I will check it out.

@@abdulla716 I don't know off hand how much has it uses per cal. There's no gauge on the regulator.

depends, labor rate could be anywhere from 100-150/hr depending on what your service company charges, contract or none. then parts used come with a markup based on mfr pricing. . if it has to be picked up/dropped off then a travel charge. I've got some open repair estimates running $500 up to $3000. the higher ones usually just result in a replacement quote. Lack of proper maintenance can result in a hefty charge. just following the user manual instructions saves a lot of money. having an annual service contract also means we find your issues before you suddenly find out you are without a working device right when you need it = cancelled cases = $$???

@kevinfrancis4513 working on it right now. Ran into a heatup error on an elara 11 and had to stop filming

@@The_Biomed Have a lab line 3870EA with that analog error and trying to acquire that calibration tool to fix it. (Bacsoft)

@kevinfrancis4513 When are you getting this message, at startup, during cycle(which phase?)? the adjunc3 pcb is your analog board, check to see if all of your connectors are on the right pins. For checking your pressure transducer, easiest way is to try and pressurized the chamber with an external pressure gauge attached.

@@The_Biomed It's a Bacsoft, and I get that error on startup. I had to reload the OS but it seems its a calibration issue i may be having. I realise Tuttnauer dictates each part must be within a value range.

@kevinfrancis4513 yes, there are cal directions in the tech manuals. There's a kit to use your multimeter with to verify values and a pressure gauge

@@The_Biomed i need to get that kit for the other machine. This machine can be programmed from the GUI and all seems to work well except that analog error. I found a EZ11 manual that is similar, am gonna check the instructions. Thanns

what other reports?

It's a rough intro video. What questions do you have?

just realized i replied from a diff account. what questions do you have?

asked and answered. I've uploaded an installation video for you

Are you getting. Message saying that? You might need some new naifon tubing. Most co2 monitors have a pm kit with it included

I made one, I just have to find time to sit down, edit and piece it together. Unfortunately the OR I was in had music playing and I couldn't get them to turn it off, that would result in copywrite failure and a video youtube won't let me post

once you remove the compression nut, it can be pulled out from inside of the chamber. If you'e is stuck, give it some more force, perhaps a pair of needle nose in a prying method, or channel locks

@@The_Biomed thanks! Having never done this before, I wasn't sure how much force I needed to get the compression nut off the nylon tube so I was being overly cautious at first.

@Pitmaster_GoldenShellback no problem, it's just brass so being weary was the right move. I keep stock of multiple sizes and ferrels just in case. They do strip and warp easily.

without seeing the unit, I'd have to surmise that your water level sensor is dirty, or malfunctioning. the midmark sterilizers use a continuity circuit to detect when there is the right amount of water in the chamber. water low is because all of your water is in the chamber, (and floor?)

I don't have a good one yet. I requested the contec ms200 Sim. The listed capabilities will meet our needs.

@@The_Biomed I meant the knob contraption that can allow steady flow from the compressor.

oh, i usually default to a Parker Watts R364. then you just have to get caps and fitting for your application

That will do. All your steam is escaping thru the safety valve. Did you drop a wore brush Into it to clean out the seat as well? You could just plug it and run a cycle. Just have to keep an eye on the pressure readings

@@The_Biomed Yes, I cleaned the seat on the Air Valve but didn't test it after cleaning it. I'm going to replace the Safety Valve first, run a test. If it fails again then the Air Valve/Plunger Assembly is next.

Soooooo many screws, lol
