Table 5: Controller Faults (indicated on the controller)
CAUSE
Emergency stop button has been
pressed.
Blower is blocked, damaged or blower
motor is faulty.
Compressor operating above rated
pressure.
Low coolant level.
High ambient temperature.
Insufficient cooling air.
Dirty, blocked coolant cooler (cooling
air side).
Blower motor direction of rotation
incorrect.
Controller software has been changed.
Remote start button is pressed after
compressor is running or remote start
button remains closed.
Remote stop button remains open and
either start button is pressed.
Sensor is missing or faulty.
Insufficient cooling taking place.
A fault has occurred.
Calibration done with pressure in
compressor.
System leak.
Minimum pressure check valve faulty.
Blowdown valve faulty.
Loss of control power.
Drive system fault.
Communication wiring faulty.
Drive faulty.
Controller faulty.
Communication wiring faulty.
Drive faulty.
Controller faulty.
Faulty pressure transducer measurement. Calibrate and validate the wet sump and package discharge
Moisture separator condensate drain
trap faulty.
Separator element dirty or blocked.
Faulty pressure transducer measurement. Calibrate and validate the after cooler discharge and package
Moisture separator condensate drain
trap faulty.
Blockage in dryer.
Dryer HE filter dirty or blocked.
Loss of outputs of control power.
REMEDY
Identify reason why, repair fault, disengage button and reset controller.
Remove blockage, repair or replace damaged components.
Check and modify settings. Review system requirements and contact
your local Ingersoll Rand representative.
Check for leaks. See also 'discharge air is contaminated with coolant' .
Top up coolant.
Review installation and system parameters.
Check ducting and cooling air path.
Clean or replace.
Wire correctly.
Recalibrate all sensors and check setpoints.
Check operation of buttons or operating procedures.
Check operation of buttons or operating procedures.
Install, repair or replace faulty sensor.
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.
Repair fault / reset controller.
Depressurize and re calibrate with pressure pipe to sensor
disconnected. If fault still exists, replace pressure transducer.
Located and repair.

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

Ensure condensate drain system is functioning properly, and
condensate is being drained. See Table 4: Troubleshooting Chart.
Ensure dryer blockage is not due to freeze up from refrigerant leaks.
Change HE filter.
Check controller outputs (110V AC) power supply (fuses/mini circuit
breaker).
