The tank, compressor head, and components need be rated at what you want set the compressor unit pressure to, the safety valve will keep from exceeding the lowest of those limits. If you suspect the safety relief valve needs replacing because it has weakened, then replace the safety valve with one OEM pressure values

SOURCE: What does alarm start fault

I use to start up a 25 HP Ingersol screw type compressor. The only alarms I got were from power spikes which just needed the reset button to be pushed, then the on button - and the low oil sensor would shut it down and give an alarm when the tank was about half way down. They will blow up with no oil so there is a saftey margin on oil level.

Ingersoll rand ssr 25 ep high discharge pressure.


Still believe it is the Minimum pressure check valve or the discharge line is plugged some where. The check valve may move freely at the disc but the piston should move (not so freely due to the large spring) keeping it closed. It should take about 65 lbs PSI to open check valve. Check it all again and if you find nothing you have a discharge line plugged some where.

Make sure the model of your compressor is design for 160psi if not the main motor trip off and safe valve pop. Goto Main Menu, Operator setpoint+select, Offline/Online+select, arrow up and down to change value.

Ingersoll Rand SSR EP60 60hp Compressor w/ Intellisys 39817655 controller. Need to reset target pressure. What is the secret button sequence to access programming mode on this controller? I am aware of...


OK, Compressor should be shut down and showing (ready to start) in display. Press load/unload button once then press hidden right button within 3 seconds. This will let you access the set point program. It will include language, temperature and pressure, rated pressure,etc. Make sure you look at the data tag affixed to the unit and see what the rated pressure is for your unit. You can endanger yourself and equipment by over pressurizing the components of the compressor.

I am trying to fix an ingersoll rand hxp 50 se it starts and all sensors seem to work but it trips out on low unload sump on display and there isn't any faults in the manual that can lead me to the problem...


I would first look toward the Minimum Pressure check valve. You will have to remove several covers to access. It should be located on the end of the after cooler. Also the blow down valve will cause this problem if it does not close. These units do not have oil pumps and depend on air pressure to push the oil thru the system. When the air pressure drops below 15 psi in the sump the compressor shuts down. Also check the pressure transducer to make sure it's reading correctly. A pressure gage in the discharge line would be OK. Compare the Controller read out to your pressure gage. They should be close but could read 5 PSI or so difference.

I have an ssr-epe250 and need to change the pressure setting from online @93 & offline @ 103 psi. i need 125 psi. i just changed the controller and cannot get back to operating specs i need.


controllers do not come setup for a specific compressor. you need to be able to get into the factory setup.you will then be able to change rated pressure, horsepower etc. look at the name plate to get rated pressure. once the rated pressure has been changed you will be able to set your operating pressure to 125 online and 115 or less offline
