Table 4: Controller Faults (indicated on the controller)

FAULT

CAUSE

REMEDY

Emergency stop.

Emergency stop button has 
been pressed.

Identify reason why, repair fault, disengage button and 
reset controller.

Blower motor overload.

Blower is blocked, damaged or 
blower motor is faulty.

Remove blockage, repair or replace damaged 
components.

High airend discharge 
temperature.

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 ‘discharge air is contaminated 
with coolant’. Top up 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.

Blower motor direction of 
rotation incorrect.

Wire correctly.

Check setpoints.

Controller software has been 
changed.

Recalibrate all sensors and check setpoints.

Remote start failure.

Remote start button is pressed 
after compressor is running or 
remote start button remains 
closed.

Check operation of buttons or operating procedures.

Remote stop failure.

Remote stop button remains 
open and either start button is 
pressed.

Check operation of buttons or operating procedures.

Sensor failure.

Sensor is missing or faulty.

Install, repair or replace faulty sensor.

Compressor trips indicating 
a high compressor 
temperature.

Insufficient cooling taking place.

If compressor is watercooled or sea watercooled, check 
that the cooling water is flowing. Check that there is no 
air in the water cooling system. Check that the strainer is 
not blocked.

Controller has tripped the 
compressor.

A fault has occurred.

Repair fault / reset controller.

Invalid calibration.

Calibration done with pressure 
in compressor.

Depressurize and re calibrate with pressure pipe to 
sensor disconnected. If fault still exists, replace pressure 
transducer.

Low sump pressure.

System leak.

Located and repair.

Minimum pressure check valve 
faulty.

Repair with service kit.

Blowdown valve faulty.

Repair with service kit.

Loss of control power.

Check 110V circuit breaker. 
Check wiring.  
Check contactor KM1.

Check motor rotation.

Drive system fault.

Contact your local 

Ingersoll Rand

 representative.

Change separator element 
and/or high sump pressure.

Faulty pressure transducer 
measurement.

Calibrate and validate the wet sump and package 
discharge transducers.

Moisture separator condensate 
drain trap faulty.

Ensure condensate drain system  is functioning 
properly, and condensate is being drained. See Table 4: 
Troubleshooting Chart.

Separator element dirty or 
blocked.

Change separator element.

Machine stops but no alarm 
message

Loss of outputs of control power.

Check controller outputs (110V AC) power supply (fuses/
mini circuit breaker).

Motor current fault

Loss of control power.
Sump pressure too high.
Faulty motor or Airend.

Check control power circuit and breaker.
Check separator element pressure drop.
Contact your local Ingersoll Rand representative.
