I know you have checked voltage. However please remove the fuses for control power and check,also check fu4 and 5 16volt fuses. next check power on the controller input. Don't remember terminal # but if you look in electrical cover removed to gain access, a wiring schematic will be affixed to it. I think it's on j5 terminal 36 110volts. But please check the schematic first. If you have power at the input terminal I suspect the controller is bad but continue with the following checks. If no power at terminal 36 check the hat (High Air Temperature) switch. Its located on the end of the airend and about 1/2 inch flex connected.If the hat switch is good check the emergency stop contacts. Note the power lite picks up voltage before the emergency stop and hat switch. So even though the lite is on one of these switches may be bad.

I have a ssr ep 100 and the intellisys says no control power ive tryed to clear it but it wont


Probably have a bad High air temp. switch located in the end of the compressor air end. It has control power run thru the switch. If the switch opens on temp or just goes bad you lose control power which will come up on screen as control power loss. Replace HAT switch.

I'm working on a Ingersoll rand 100HP stationary compressor with an intellisys 39875158 controller.


Make sure the model of your compressor is design for 160psi if not the main motor trip off and safe valve pop. Goto Main Menu, Operator setpoint+select, Offline/Online+select, arrow up and down to change value.

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.
