Sorry to be contradictory here, but better not to mislead or scare someone... Thepressure relief valve has absolutly nothing to do with cut in cut out pressure settings.the pressure relief valve is abrass fitting on the outside of the tank hexagonal fitting with a thin shaft coming out of the centre normaly with a ring on it not unlike akey ring .THAT is a blow off valve a safety device, that long before the air pressure is too great for the tank,will blow offthe air pressure in the tank ,try it, grab the ring and pull it out and it will dis charge any air in the tank ,that ios what it will do if thair is too great in the tank.. tanks are pressure tested and the appropriate valve fitted. NOW FOR YOUR ORIGINAL PROBLEM .you will find a control box ,useualy black or dark brown bakerlite cover,the electric cord goes into it ,also there will be another electric cord coming out and going to the electric motor that drives the compressor . If you take the cover off this you will find the cut in and cut out adjustments that allow you to set the cut in and cut out pressure as high or low as you want,that is whith in the capascity of the unit.It is self explanitory and there will be ( or should be ) instructions inside the cover .If you have any difficulty come back to me preferably with themotor and compressor sizes and i will walk you through it NOW AS MUCH AS THIS GOES AGAINST THE GRAIN, SHAG79 IT WOULD BE FAR BETTER IF YOU KNEW A BIT MORE ABOUT THE THINGS YOU ARE ADVISING THEM ABOUT EXPLOSIONS AND DEATH !!! WHAT ARE YOU-----A ******???

There should be a pipe leading from the tank to a box that looks like a water pump pressure regulator.
If the compressor does not turn off when the tank pressure reaches the preset limit and if the safety fails the unit may explode. I would replace the regulator with another. Some things are just not worth saving. the regulator can be fixed but if the compressor explodes serious damage and or death may result. I think I would go to your dealer and request another switch (regulator).....!

I just bought a used ingersoll rand ss3L3 and need to know how to adjust the pressure regulator switch. Also how to set the high and low limits.


if you want more pressure out your hose use the outlet pressure regulator. if you want more or less air put in the tank you can try to adjust the pressure switch. different models are adusted in different ways. there may be a screw between the points that make contact. adjust it up or down to see the direction you need to go. some of these switches won't let you adjust or id they do it won't be much.

Need to set low level on my compressor


That would depend on the type of pressure control switch it had on it, but all of the ones I've ever seen have it near the high pressure adjuster under the pressure switch cover- VERY HIGH VOLTAGES- RISK OF INJURY OR DEATH- UNDER PRESSURE SWITCH COVER WITH UNIT STILL CONNECTED TO POWER-

On the common switch used (A condore mdr 5) the differential is adjusted by DEPRESSING the nob & turning it.

On MDR 4 the adjuster is directly behind the high pressure adjuster. it is a flat bladed screw attached to a spring-screw in to increase cut in pressure.

You can also get pressure switches with a higher cut in pressure.
In Australia from a company called Ross Brown Sales in N.S.W

Hope this helps

from what you are describing it sounds like you are missing a couple wires somewhere or you do not know what you are looking for. The pressure switch, low oil switch motor starter coil, and overload relay should be wired in series to provide a control circuit for the motor starter. I would highly advise seeking the help of a certified electrician if you are not experienced in working with these machines. You can not only risk personal injury, but also damage a lot of expensive electrical item's real quick if it is not done correctly.

Adjusting the pressure on the 2340-E


most air compressors have a pressure switch on them.this is used to adjust the desired pressure you want to reach.the second adjustment is for setting the pressure for when you want it to cycle back on.lets say you want it to run at 100 PSI.one of your adjustment in this box will control this , when you are using the unit and the pressure starts to drop to lets say 90 PSI you can adjust the unit to cycle
