3. The values sensed by the sensors are displayed on the test station computer:
– Temperature in the supply line
– Conductivity
4. The measured values from the sensors are compared with the reference values of the
cooling unit.
Result
The test is passed if the measured values lie within the tolerances.
● Temperature in the supply line ±5 K
● Conductivity ±0.2 µS/cm
● Temperature in the supply line ≤40 °C
● Conductivity ≤2 µS/cm
3.3.4 Leakage monitoring
Fundamentals
The drive cooling circuit is equipped with a leakage monitoring function. The leakage sensor
function is tested.
Test procedure
1. The cooling system is switched on. The auxiliary voltage is present.
2. Moisture/water is applied to one leakage sensor.
3. A message is displayed on the test station computer.
Result
The test is passed if a message is displayed on the test station computer.
