14 | ENGLISH Original instructions INS00025-A
Fault Possible cause Possible remedy
Supply voltage too high or too low Check power supply
Incorrect supply frequency Check power supply
Bearings damaged or worn Replace bearings
Only for 3~ motors: phase voltage imbalance Check power supply
Only for 3~ motors: STAR instead of DELTA con-
nected or DELTA instead of STAR connected
Check wiring diagram
Connect correctly
Only for 1~ motors: wrong or defective capacitor Replace capacitor
Fan motor overheats while running Only for 1~ fan motors with start capacitor: Start ca-
pacitor does not disengage after motor has started
(continuously on)
Replace start capacitor
Fan rotates in wrong direction 1~ fan motors: capacitor incorrectly connected Connect according to wiring diagram (contact sup-
plier)
3~ fan motors: supply incorrectly connected Swap any 2 of the 3 phases of the supply
Fan speed (rpm) is too low Supply voltage too low Check power supply
Incorrect supply frequency Check power supply
Only for 1~ fans: wrong or defective capacitor Replace capacitor
Only for 3~ fans: STAR instead of DELTA connec-
ted
Connect as DELTA
Check wiring diagram!
3~fan motors: Phase failure Restore all 3 phases
Fan speed (rpm) is too low Belt not tight enough Adjust the tension of the belt or replace the belt
High power consumption Fan overloaded Check for overloading of fan system (intake or ex-
haust blocked?)
Fan speed too high Check supply voltage and frequency
Bearings damaged or worn Replace bearings
Unusual or excessive noises Impeller hits fan housing Check installation and fixings and alignment
Fan is operating in stall point Lower system resistance
(Intake or exhaust blocked)
Bearings damaged or worn Replace bearings
Unusual or excessive noises Only for 1~ motors with start capacitor: Start capa-
citor does not disengage after motor has started
(continuously on)
Replace start capacitor
Use original spare parts only.
