IR screw comp. trouble code, clear it off the computor

by Dan
(berkey, ohio )

after servicing compressor it would have a trouble code that will show up and say service, is there a reset that you have to do to the computor to clear this out of the system so it knows you serviced it? and if so how do you clear it? Thank you.

Ingersoll Rand 5hp 80gal 175 max psi - will not maintain delivery pressure

by Jeff
(Birmingham, AL)

Compressor will not maintain delivery pressure.

I have a new IR 80gal, 5hp upright compressor, model TS5.

The compressor is wired appropriately on its own 40 amp breaker with 8 guage copper wire.

The breaker panel or power source is within 3 feet of the compressor.

The compressor comes on and builds psi correctly and shuts off at the factory setting of 160 psi.

It has a 1/2 inch delivery valve. I purchased separately a 1/4 inch regulator(the only size I could find)and have 3/8 inch hoses. My problem is that no matter what I do, pressure cannot be maintained at the tool. For example: If I hook up a standard impact driver and pull the trigger, the pressure immediately comes out hard and strong but quickly(within 3-5 seconds)slows down to a very low rate of discharge.

If you let go of the trigger the pressure quickly builds back up in the line but when you pull the trigger again it does the same thing.

I have tried this process with a number of tools, with and without the pressure regulator attached with the same exact outcome.

I have tried no regulator only using the 1/2 delivery necked down to 3/8 to fit my hoses. Still the same outcome.

How can I maintain delivery pressure? The compressor application is mostly for automotive repair, very little body work and a lot of impact driver, air ratchet and cut-off tool use.

Also, the compressor advertises that it is "continuous duty". Can you tell me what this means exactly?

Thank you for your helop and this website!

Jeff, continuous duty means that you can run this compressor constantly, and it is built to take it. It will not, if installed correct, and it sounds like yours is, overheat and go off on thermal overload.

Your air compressor also should be able to deliver in the area of 20 CFM of compressed air at 90 PSI continuously.

If your air tool uses more air than that, your compressor is too small, and you will continually wait for it to regenerate to be able to use the tool at proper pressure.

Having said that, your post has all the earmarks of an air line restriction of some sort. A 1/2" discharge line should have no problem running a typical impact wrench.

You say you have removed the regulator? Did you plumb right from the discharge line, or did you plug the air hose into a coupler on the discharge from the tank?

If you removed the regulator and plumbed directly to the air tool, and the pressure drops so quickly in the 3/8" I.D. hose then I suspect either your hose may be too small to allow enough air to get to the tool, or the connector on the air hose is not opening the internal ball check on the discharge coupler fully.

If your hose is longer than 25', consider getting a 1/2" hose. But first, make sure the connector and coupler mate properly. If they are two different brands, that might be your problem.

See Couplers and Connectors for more info.

Cheers,

Bill

Bill,

Thanks for your help. It was a bad hose. The hose evidently was coming apart from the inside and restricting air flow and it could not be seen from the outside. I started swapping out hoses and fixed the problem. You were dead on.

My 5hp 230 volt IR Compressor will not re-start

by Jim
(Waterford, PA, USA)

The 5 hp compressor was bad when I was given the machine. I installed a 3 hp compressor on the 80 gallon tank from a different machine with a bad motor. So now the 5hp 230 volt single phase motor runs the 3hp compressor.

When the tank is empty everything runs just fine - up to pressure and shuts off and I hear the unloader hiss off the head pressure.

Use the air and the motor kicks in and runs at what seems like 1/2 speed for 3 -4 seconds and trips the 20 amp 230 volt breakers.

Had the motor megged out and all looked okay. Had the Capacitor (760 - 840 mohms) checked out and it looked okay. Run the motor by itself and all okay.

I emptied the tank again and same result. The motor does not even get hot when filling the tank.

I replaced the capacitor with a similar size (708 - 850) that was available and the motor kicked out after 3 seconds of 1/2 speed running.

Any ideas ? Hook 2 capacitors in parallel together ? Thanks

Jim, it sounds like it could be a power supply issue to me. Any chance of that?

If the caps are OK, and the motor is fine, then what might trip it out is low power.

Anyone else?

Cheers,

Bill

230 Volts is confirmed
by: Anonymous

230 volts to the contactor is confirmed. The motor runs fine with an empty tank start-up so the voltage should be okay.
Is there a start capacitor kick-out switch that could be bad? If so where is it.
Thanks
