1. Remove the low voltage (measurement signal) connector from the electric machine enclosure. Be
careful not to damage the cables and joints.
2. Mount (glue) an additional PT100 temperature sensor close to the end of the windings at the
opening. Use resin/glue specified for correct temperatures (Temp.class in the rating plate, class F /
155 ºC).
3. Connect the PT100 sensor to the low voltage connector (replace the failed sensor connection by the
new connection).
4. Remount the low voltage connector to its place.
When reading the temperature (resistance) values from the additional sensor, add +15ºC to the
measured value. This gives more correct estimation of the inner temperature of the electric machine. In
case of the temperature measurement failure and using additional temperature sensor, replace the
electric machine as soon as possible, but no later than in two months.
