Ingersoll Rand SSR M11 solenoid clicks but stays in unload
Hi Bill, I have an Ingersoll Rand SSR M11 that I have inherited and am presently trying apply to a cabinet blaster. The issue I am having is that it wont build pressure and seems to be stuck in unload.
I can build pressure in the line only when I disconnect the air pipe that runs to the inlet from the top of the oil seperator.
I start the compressor in unload, no problem, let the oil warm up for a couple of minutes and then switch from UNLOAD to NORMAL but even though I hear the solenoid click, air is still running from the top of the seperator to the back of the air inlet and the pressure is keeping the valve closed?
I have checked the solenoid for power and seems fine 6v in unload and 48v in normal.
Kind Regards Lee
