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.
