Question about Ingersoll Rand Stationary Air Cooled Rotary Screw Compressor 10 Hp, 35 Cfm At 125 Psi, Model# Ep

1 Answer

I have an ssr ep60 IR COMPRESSOR. I had the starter interface board short and take out the 24v secondary of the xformer (or vice-versa). I replaced the interface board and the xformer, but now I get a sensor error on the package discharge. I swapped sensors to check, but it stays with the package discharge. I'm certain everything is wired correctly and have double checked to make sure I have no strands touching other wires on the board The sensor reads 85 degrees. Could the original problem have taken out my analog barrier board? How do I troubleshoot this? The unit goes into alarm with this error immediately when you push start. Contactor will not engage. Thanks-Mike

I have a SSR-EP60 air compressor and am having a problem with it unloading. It would shut off for high pressure (145). I changed the air piston to the intake butterfly and seems to be a little better. I...

If the pressure continues to rise, the inlet valve is not closing completely. Remove the top of the air cleaner box and look down at the inlet valve butterfly. When the compressor is down or unloaded, the valve should be held closed by an internal spring in the air cylinder. If it's not, the mounting stud on the bracket may have come loose and moved, or more likely the spring in the air cylinder actuator is broken.

This actuator has gone thru at least 3 revisions. I just replaced the cylinder on our EP60 because the spring had broken in two places and wouldn't come anywhere near closing the valve.

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.

Does not switch on

Unplug the TV. Carefully remove the back cover of the TV. Check continuity of the mains cord-Not ok-replace the cord-ok-Connect mains cord to the wall plug and switch one, take care not to touch exposed parts to avoid electric shock, which could also be fatal, connect the multimeter across the leads soldered on to the board and ensure that AC is in. Check secondary power supply of the SMPS for appropriate voltages (say 24V, 12V, 5V, 7V DC etc.). If that is ok, the problem lies in the board. You may have to go for a schematic of the TV and trouble shoot. In my opinion, the problems might be in the power supply. Once that is set right, check for shorting of DC supply to the TV using an analogue multimeter, setting to x1K Ohm. If reading shows low ohms or short, on checking up with red probe to positive and black probe to negative and vice verse, there is/are components shorting in the main board. You may have to check the components using your multimeter, ie., COLD TEST.

F8 heat low it goes up to 494 and stops there

It generally is the IR Element that has gone bad. Look for burned wiring where the IR Element enters the oven cavity. Check for continuity through the IR Element.

1. Check that the blower motor is moving air.
o Blower motor is not moving air: Check blower motor assembly
and verify motor is stalled. Unplug oven and correct obstruction or
replace motor. (For access to motor shaft, remove top panel.)
o Blower motor is moving air: Verify high-limit thermostat is
not tripped. See the high-limit thermostat information below.
High-Limit Thermostat:
o Thermostat tripped: Reset and determine why the thermostat
tripped (See Figure 38, Item 114). Look for excess build up of
grease inside the oven or any other source for a fire.
o Thermostat is not tripped: Check main convection heater.
1. Convection heater is defective: Unplug oven and replace the
convection heater and verify the K4 SSR (Figure 37) is not
shorted across output.
2. Convection heater OK: Check the K4 SSR.
o K4 defective: Unplug oven and replace.
o K4 OK: Unplug oven and verify all wiring. Verify P1 voltage on
I/O board is 5.0VDC (+/- 0.02) -

Air compressor kicks on but fan doesnt and vice versa

I assume you mean the condenser fan motor ? Try to manually spin it. If it is hard to turn, change the motor. If it spins freely, change the capacitor.
