5.0 Indications – Disturbance origins
Triggering of motor overheat protection (TK) can indicate
- wrong direction of rotation ( I ~ 2x I
- built up of dirt, hard running impeller and/or ball bearing failure
- too high air flow temperature
Abnormal noises can mean
- wrong direction of rotation
- worn out ball bearings
- bad vibration isolation to other buildings and ducting systems
Vibration can originate from
- unbalanced or dirty impellers
- insufficient vibration isolation from buildings and ducting systems
Extreme reductions in performance can occur
- with wrong direction of rotation
- if resistance to air stream through ducting and accessories (grilles, shutters, filters etc.) is higher than designed
