Warnings
A:2040
“Freeze Warning
(Dryer Package Only)”
Dryer low temperature warning.
This serves as a log that the compressor is running in low-
ambient conditions.
A:2050
“Dryer High Pressure
(Dryer Pressure Only)”
Dryer high pressure warning.
This is a locking switch and the dryer high pressure switch
must be reset (contact closed) before this warning can be
reset.
A:2118
High Airend Discharge
Pressure
Discharge pressure is greater than
offline pressure by 1.45 psi for a
period of 3 seconds or longer
Discharge pressure must fall to the rated pressure value
before the unit is available for reload.
A:2128
High Airend Discharge
Temperature (above
105°C)
Compressor operating above rated
pressure. Check and modify settings. Review system requirements
and contact your local
Ingersoll Rand
representative.
Low coolant level.
Check for leaks. See also if discharge air is contaminated
with coolant. Top off coolant.
High ambient temperature. Review installation and system parameters.
Insufficient cooling air. Check ducting and cooling air path.
Dirty, blocked coolant cooler
(cooling air side).
Clean or replace.
Fan motor direction of rotation
incorrect.
Wire correctly.
A:2816 Power Failure Detected
If power supply to controller is
inconsistant.
Check power supply.
A:4804 Service Due
Service interval hours counter has
reduced to zero
Service compressor.
Trips

E:0119
High Airend Discharge
Pressure Discharge pressure is greater than
offline pressure by 4.35 psi Check and modify settings. Review system requirements
and contact your local
Ingersoll Rand
representative.
E:0125
Temperature Sensor
Fault Signal out of range (<-50°C or
>250°C)
Install, repair or replace faulty sensor.
E:0129 Excess Temperature Shutdown limit exceeded
Can be reset only when airend discharge temperature is
lower than 107°C.
E:0866

Low 24V DC power supply to controller
is low. Check controller power supply and call your local
Ingersoll Rand
representative.
E:0821
