long cycle times

my unit is taking nearly double since the last visit of the service team. our facility has since decided to cancel that contract and keep the money in house. It is now mine to troubleshoot, I have looked at all seals, and valves, and the steam trap, and have not been able to come up with why the cycles are taking so long, I checked the printout, and it appears that it is reaching pressure and temperature but it is taking quite a while to do so. I checkes service inputs, steam it at 60 psi, 287 degrees Fahrenheit, vapor quality is unknown. Water is at 60 psi, 70 degrees Fahrenheit. I am pretty new to the BIOMED world, any help would be greatly appreciated.

I figured it out, the steam trap was pluged, and the pressure regulator was adjusted down farther than it should have been.

with cleaning the steam trap, and proper adjustment of the pressure regulator unit ran an average of 7 seconds over projected cycle times.

Have you verified that S2 & S9 are opening fully and the seat for each valve is clean? Or

does the pressure drop below 40PSI during conditioning? If the pressure drops that low you either have a bad heating element or lost power to one elements. Test the voltage at the input of the elements contactor and measure the continuity of the elements “with power off”. Heating elements should be ~ 22-28 Ohms.

@Cbet_Matt

Are you refering to the optional steam generator?

My unit does not have the steam generator, it operates on facility steam.

If you steam trap was plugged with debris you might want to check if there is a screen in the chamber drain.

I checked it.

The Steam trap I was refering to was external to the machine.

Sorry for the confusion.

I assume when you say you've checked the steam trap, you mean the trap that is part of the manifold under the chamber? Not the the stand alone jacket trap. Also, Steris gauges suck. You need to know an accurate chamber and jacket pressure to determine correct function. Always keep a couple good gauges on hand. Could be as simple as a steam regulator adjustment.

I checked that one also, it was ok.

I agree with the Guages, i have a a couple pressure and vauum guages i bought, decided to do so when the steris guage said it was at 40 psi in the door seal when i had it removed to replace it...lol
