Test A08 - Dr Mr Tmp [Traction Motor Temp]
Test A08 - Dr Mr Tmp [Traction Motor Temp] Traction Motor temperature is displayed. While operating, the TM continuously monitors traction motor temperature. If the temperature gets too high, performance is reduced until the motor cools down. •
Normal operation: ambient to 284°F (140°C)
•
Travel speed reduced linearly between 285°F (141°C) and 310°F (154°C)
•
Code 2A is displayed between 311°F (155°C) and 373°F (189°C) and speed is reduced to 1.0 mph (1.6 km/h)
•
Code 2E is displayed and travel is limited to 1.0 mph (1.6 km/h) at 374°F (190°C)
With the lift truck at rest and at ambient temperature, compare the temperature displayed to the actual ambient temperature. If the temperatures are not within several degrees, refer to Diagnosis and Repair.
