Overheated motor�
The fan impeller does not turn in the
correct direction�
Speak to Systemair technical support�
A phase loss occurred� If the motor is a 3-phase motor, make
sure that no phase is missing�
Motor damage� If it is possible, measure the resistance
to do a check of the motor winding�
There is blockage in the motor� Speak to Systemair technical support�
The fan speed does not get the
nominal value�
Defective motor winding� If it is possible, measure the resistance
to do a check of the motor winding�

motor cool down to ambient tempera-
ture� Measure the resistance at the
free ends of the motor cable� All 3
measured resistances should be
equal and in the range as in the table
above� Otherwise, the motor is
damaged�
The speed control is not correctly set� Set the speed control correctly�
The fan impeller cannot turn freely
because of mechanical blockage�
Remove the blockage�
Phase loss occurs� If the motor is a 3-phase motor, make
sure that no phase is missing�
The motor does not rotate�
A component in the power supply is
defective�
Do a check of the power supply�
Replace defective components and
connect the power supply again�
The electrical connection is not
correctly done�
Make sure that the electrical connec-
tion agrees with the wiring diagrams�
A phase loss occurred� If the motor is a 3-phase motor, make
sure that no phase is missing�
Overheated electronic component
The ambient temperature is too high� Make sure that the product is
applicable for the installation location�
