Reason	Solution
IF *iE * error pops up when compressor powered up	Check the multi cable terminal and cables are connected properly on the control board of the main inverter, when there is no power on the compressor for at least 2 min after all the lights on the display is off. The multi cable to check is indicated with a blue circle in the picture below.
Input voltages are too low	Check input voltages when compressor running. Make sure all phases (for 3 phase compressors) are alive and within the voltage limits
Discharge valve is not discharging enough air or not discharging at all when compressor goes 8 PSI (0.5Bar) above the PSET of the compressor	Please refer to procedure at this link
Electric motor is faulty	Replace motor if windings are damaged or replace bearings if bearing is damaged
Airend is seized or stuck	Rotate the coupling in between airend and motor when there is no power on the compressor and emergency stop is pressed. There must be no light on the inverter and breaker on the wall must be switched to off before performing such test, Safety and Health precautions must be taken to avoid and hazard before performing any test. if air end is not freely turning when there is no pressure in the compressor replace the airend. Before performing this test make sure all the internal air is discharged through the discharge valve. If needed open the oil filler plug to ensure there is no air left in the compressor.
