ABB DC Tachometer Generator TDP 0,7 XPY

- Check ball bearings for noise, running smoothly. Service life approx. 20 000 hours (lubricated for life); however, service life depends on speed, environmental conditions and load. Observe removal from installation instructions!;

- After approx. 16 000 - 20 000 hours of operation

- Check carbon brushes; blow carbon brush dust out of the machine using dry, oil-free compressed air; check ease of movement. When changing carbon brushes (service life approx. 10 000 - 20 000 operating hours depending on environmental conditions and speed) ensure the new brushes are of the same quality and type.;

- Check fastening screws are seated correctly.

- Cleaning: Blow-clean the machine using dry, oil-free compressed air. Do not use cleaning agents that damage the coating. Do not use inflammable cleaning agents.

- Check coating. If the protective coating is sufficiently damaged, repaint to prevent risk of corrosion (recommended).;

- If the TDP 0,7 XPY has not been in use for a long time (more than 6 months).

- Check the insulation resistance of the windings (greater approximate 1-5 mega-ohm). To measure the insulation resistance disconnect all outgoing lines from the generator. Contact the manufacturer if the resistance reading is less than 1 mega-ohm.;
