3.3 Cooling system test

3. The values sensed by the sensors are displayed on the test station computer:

4. The measured values from the sensors are compared with the reference values of the

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

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.
