TEMPERATURE MONITORING WITH THERMAL SWITCHES TO SERIES 6/95

A thermal switch 1B6 or 1B7 is mounted to each or the traction motor brush holders. When the temperature
of a traction motor reaches 160 °C, the battery negative signal normally applied to connector 1X13:23 is cut
off. The maximum current or motor voltage is reduced to prevent damage to the traction motors. However,
it is possible to drive the truck at reduced speed.
