There are 5 different reasons “Fail to stop” alarm is triggered. IT can be any one of the reasons or a combination of multiple reasons. Pay attention when correcting the issue, there could be more than one reason triggering “Fail to stop” alarm.
Please check the below chart for 5 possible reasons of “Fail To Stop” Error;
| Reason | Solution |
|---|---|
| Electrical input phase sequence may be wrong | Swap any two of the three input phase wires |
| Input voltage is higher or lower than permissible values | Correct input voltages according to the safe working voltage ranges. Voltage at the compressor power input can be seen at the compressor display |
| One of the power input phases does not have power | Check all input phases, make sure all three phases carry the right voltage |
| There is an unbalance in between input phases | Max unbalance accepted in between phases is 2%. more than that must be corrected |
| There is pressure after the compressor higher than compressor is allowed.(Pressure can be seen on the compressor display as pressure measured) | Discharge excess pressure in your compressed air system. Set other compressor pressure levels so that compressed air pressure in the system does not exceed the max pressure setting allowed for your compressor. |
| Current drawn by the main motor or the fan motor is above permissible limits | Check input voltages make sure they are correct according to the warning above |
