Possible cause
(If present) VFD (Variable Frequency Drive) defect-
ive
Thermal protection activated
(Fan motor has overheated)
Impeller blocked
Only for 1~ fan motors: wrong or defective capacitor Replace the capacitor
Temperature too low for the bearing grease
Fan is overloaded
Fan motor overheated due to dirt in cooling fins.
Supply voltage too high or too low
Incorrect supply frequency
Only for 3~ motors: phase voltage imbalance
Only for 1~ motors: wrong or defective capacitor
Only for 1~ fan motors with start capacitor: Start ca-
pacitor does not disengage after motor has started
(continuously on)
1~ fan motors: capacitor incorrectly connected
3~ fan motors: supply incorrectly connected
Supply voltage is too low
Incorrect supply frequency
Only for 1~ fans: wrong or defective capacitor
Only for 3~ fans: STAR instead of DELTA connec-
ted
3~ fan motors: Phase failure
Fan is overloaded
Fan speed is too high
Impeller hits fan housing
Fan is operating in stall point
Bearings are damaged or worn
Only for 1~ motors with start capacitor: Start capa-
citor does not disengage after motor has started
(continuously on)
Recycling
The main materials used in the electric motor are copper, steel and
aluminium.
Most of the fan parts have the recycling symbol with material code listed on
them to facilitate proper recycling. Some parts are made of easy to identify
materials such as steel, and have no recycling symbol on them.

Possible remedy
Check VFD (refer to VFD manufacturers' instruc-
tions)
Clean the motor
Check for overloading of fan system (intake or ex-
haust blocked?)

Remove the blockage
Do not operate the fan outside the ambient temper-
ature range as specified on the rating plate and
technical data sheet
Check for overloading of the fan system (intake or
exhaust blocked?)
Clean the motor
Check the power supply
Check the power supply
Check the power supply
Replace the capacitor
Replace start capacitor
Connect according to wiring diagram (contact sup-
plier)
Swap any 2 of the 3 phases of the supply
Check the power supply
Check the power supply
Replace the capacitor
Connect as DELTA
Check wiring diagram!
Restore all 3 phases
Check for overloading of the fan system (intake or
exhaust blocked?)
Check the supply voltage and frequency
Check the installation and fixings and alignment
Lower the system resistance
(Intake or exhaust blocked)
Replace the bearings
Replace the start capacitor
