SOURCE: I have a ssr ep-15

I would say it's the piston ring(s) or vlave(s) or both leaking by -- in that case it would need a rebuild.

SSR EP 40 SE shuts down on low unload sump what is probable cause


I would look at the minimum pressure check valve first. If it is stuck in the open position you can not build sump pressure before the unit shuts down. MPCV is located on the top of the separator tank. You can remove it. Check to see if the plunger with the teflon disc is free and not damaged. These valves often seize up due to dirt,rust and condensation. If it is stuck it will need to be disassembled, cleaned and lubricated. It needs to be free enough to slide in the valve body by hand. If the o-ring is bad or damaged you will need to get a kit from IR. I have not been able to find one with out buying a kit. Next I would look at the blow down valve. It is located beside the MPCV at the top of the separator tank. If this solenoid is open it will not let the sump build pressure. Next I would check the Inlet valve actuator cylinder if so equipped. With out the serial number I dont know which type inlet valve is on the unit. If it does have a cylinder does it operate correctly. Is there any free play in the cylinder. If so replace it. Is the cylinder to inlet valve coupling cracked. Remove and inspect. Is the bolt tight at the rear of the cylinder. Will it let the cylinder move. If so you will need to loosen the bolt. Set the controller so you can see sump pressure. Start the unit and Slowly open the inlet valve by sliding the cylinder in and out to get 25psi sump pressure. Then tighten the bolt. if sump pressure drops below 15 psi it will shut down on sump pressure alarm. Good luck !!!

Ingersoll Rand SSR compressor shuts down loaded or unloaded with no alarm, and then shows ready to start . Will not run more than a few minutes either loaded or unloaded. installed meter on incoming power...


When it shuts down, press DISPLAY SELECT button once and use the up down arrows to see the code just before shutdown.

HIGH AIREND TEMP

HIGH AIR PRESSURE

LOW SUMP PRESSURE

PRESSURE OR TEMP SENSOR FAIL

CHECK MOTOR ROTATION

MOTOR OVERLOAD

FAN MOTOR OVERLOAD

STARTER FAULT

I am assuming this has a Intellisys controller.
