What does Message -06- mean on an Ingersoll Rand SSR Intellisys?
Short answer: Pressure sensor failure. If your Ingersoll Rand SSR Intellisys (10-40 HP) is showing Message -06-, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
The controller detected an invalid signal from the pressure transducer. A common trigger is sump pressure failing to reach at least 15 psi within about 10 seconds of startup — from an air leak in the tubing, a solenoid valve problem, or a failed transducer.
Which machines show this?
Ingersoll Rand's SSR rotary screw compressors in the 10–40 HP class fitted with the original Intellisys microprocessor controller — a long-lived population of machines from the 1990s onward, many still in daily service. This controller reports faults as numbered messages in the form Message -02- through -08- on a small numeric display, each number mapping to one condition: motor overload, high temperature, high pressure, sensor failures, and the emergency stop pair. Practical tip: -07- and -08- work together — -08- simply means someone tried to clear the E-stop message while the button was still pushed in, so twist the button out before pressing SET.
What causes it?
- Air leak in the small control tubing keeping sump pressure from building
- Solenoid valve problem at startup
- Failed pressure transducer or its connection
Can you fix it yourself?
Partly — listening for tubing leaks while depressurized and reseating the transducer connector are safe checks. Persistent codes are electrical diagnosis.
Step by step — what to try, in order:
- Listen and look for obvious air leaks at the small control tubing while the unit is depressurized
- Check the transducer's electrical connector is clean and fully seated
- Reset and observe whether the displayed pressure tracks reality as the unit builds pressure
When do you need a technician — and why?
Testing the transducer circuit and interface board involves live control wiring and calibrated readings — not something to probe without training.
If it does come to a service call and you're in Nashville, TN or Birmingham, AL, we maintain independently compiled lists of local companies that service industrial air compressors — real businesses with verified contact information, none of whom paid to be listed.

When does Message -06- on an Ingersoll Rand SSR Intellisys (10-40 HP) need a technician?
Testing the transducer circuit and interface board involves live control wiring and calibrated readings — not something to probe without training. If the code persists, have a technician test the transducer circuit and interface board — that diagnostic involves live control wiring and is not a DIY job.
