Maintenance and servicing

The torque transducer T5 are to a large extent designed to be maintenance
free. Only the sliprings and carbon brushes are subject to slight wear, which
must be monitored.
For reasons of functional safety, the carbon brush dust should be removed
from the housing of the transducer (see Tab.5.1). To do this, remove the cover
screwed on at the side and carefully remove the carbon dust or dirt present
using a fine brush and dry compressed air.
Replacement of the carbon brushes can only be carried out in the factory at
Darmstadt.
