Troubleshooting
Malfunctions when starting
Sluggish start-up
Possible causes
Turbochar- Turbocharger contaminated
ger
Damaged bearing
Rubbing rotor
Foreign object in turbocharger
Vibrations
Possible causes
Turbochar- Rotor unbalance
ger
Damaged turbine or compressor
Damaged bearing
Rubbing of rotating parts
Normal behaviour, no malfunction
Turbochar- Minor uniform wear around the periphery of rotor components,
ger caused by slight local rubbing of adjacent components, is permis-
sible. The compressor blades and turbine blades are then short-
ened somewhat. Certain tolerances must be observed to avoid a
significant loss of efficiency.
 If there is any doubt about the extent of rubbing, then an ABB
Turbocharging Service Station must be contacted.
 Have a dimension check carried out by an ABB Turbocharging
Service Station.
