You need to recalibrate the stepper motor on the inlet valve which only a ingersoll rand tech can perform cause it is kind of tricky .and if that doesn't fix it it could be just a simple adjustment or a bad stepper motor or a broken inlet valve arm or worse a bad control board good luck.

WHAT IS THE MEANING OF THE YELLOW SYMBOL OIL PRESSURE WITH AN EXCLAMATION MARK


If you have a yellow oil pressure warning light displaying then you may have 2 problems
1. Your oil level is way too low and needs topping up which very often means you are a sloppy owner that does not bother to regularly check the oil level in the engine and probably the other fluids as well.

2. There is a problem with the oil pressure and it is below the minimum needed to lubricate the engine.

What you need to do:

1. Check the oil level and top it up to the max level with the correct grade and type of oil as specified by Toyota for that engine.
Do not overfill the sump.
2. Check to see if the oil pressure warning is continuing to display when the sump has been filled to the correct level. If you still have the oil pressure warning you need to have it investigated and the cause of the low pressure rectified otherwise you will destroy your engine if you continue to run it with less than minimum pressure. A mechanic needs in the first place to connect an independent oil pressure gauge to the engine to check the actual pressure readings. This will also eliminate any possibility that there is an issue with the oil pressure sensor and sender unit (which is not likely). .

Why would the oil light stay on?


That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

Ssr up series 30e-40 Ssr 50 - pe low sump


compressor idling to long or inlet valve not opening

Low sump pressure


well with out a model number this is a tought one , but if your unit is less than 10 hp the low sump pressure is most likely caused by a dirty suction screen or worn out oil pump if its over 10 hp then low sump most likely is caused by a dirty inlet air filter

Check sump pressure? can you tell me what that means


Sump pressure is the back pressure created within the oil sump by pressure leaking past the piston rings. The pressure is usually very low due to the venting of the sump thru the oil sump vent (usually a tube or removable plug used for adding oil). If the vent was replaced with a plug, then pressure will be very high and cause oil leak. Higher sump pressure is also caused by adding too much oil into crank-case. If you are having other problems with compressor, post again. Good luck.

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 !!!

What would cause load unload sump pressure?


Is this a rotary screw unit? Was it low unloaded sump pressure? If so the most probable cause is the minimum pressure check valve located under the aluminum cap on the seperater tank (oil tank). The check valve piston binds in the housing due to rust, dirt,etc. If you are going to attempt the repair your self I would recommend purchasing rebuild kit before disassembly.
If this problem is with a 2475 unit I would look at the pressure switch. If you are saying the unit starts/stops/starts etc and it is equiped with a low oil level switch the oil level is low. fill it to the oil fill plug threads.

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.
