What does E:0115 mean on an Ingersoll Rand Xe-series controller?
Short answer: Pressure sensor fault. If your Ingersoll Rand Xe-series controller (Xe-50M/Xe-70M, R-series rotary) is showing E:0115, 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?
Shutdown trip: the pressure transducer's 4-20 mA signal went out of range (below 3.8 mA or above 20.8 mA), which means the sensor or its wiring has failed.
Which machines show this?
modern Ingersoll Rand R-series rotary screw compressors controlled by the Xe-50M and Xe-70M — the current web-enabled controller family with a full-text display. Faults come in two clearly labeled classes: A: codes are alarms, where the machine keeps running but wants attention (A:2118 high pressure, A:2128 high temperature, A:4804 service due), and E: codes are trips that shut the compressor down (E:0010 emergency stop, E:0020 motor overload, E:0129 excess temperature). Practical tip: the letter tells you your time budget — an A: code is a scheduled-maintenance conversation, an E: code that repeats after one reset is a service call, and third-party code lists sometimes mislabel these, so trust the manual's definition.
What causes it?
- Pressure transducer's 4-20 mA signal out of range — a failed sensor
- Loose, wet, or corroded sensor connector
- Pinched or damaged sensor cable
Can you fix it yourself?
Sometimes — a powered-down connector and cable inspection plus one reset catches the loose-plug cases.
Step by step — what to try, in order:
- With the unit powered down, check the pressure sensor connector for looseness, moisture, or corrosion
- Inspect the sensor cable for pinches or damage
- Reset and see whether a plausible pressure reading returns
When do you need a technician — and why?
A returning fault needs the 4-20 mA loop tested with a meter and the transducer replaced — control-loop diagnosis, not guesswork.
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 E:0115 on an Ingersoll Rand Xe-series controller (Xe-50M/Xe-70M, R-series rotary) need a technician?
A returning fault needs the 4-20 mA loop tested with a meter and the transducer replaced — control-loop diagnosis, not guesswork. If the fault returns, call a technician to test the 4-20 mA loop and replace the transducer.
