Sensing The Actual Dc Link Voltage; Switching Thresholds Of The Optional Temperature Evaluation Device; Safety Shutdown (Optional) - Siemens SINAMICS G150 Reference Manual

3.2.6

Sensing the actual DC link voltage

Fundamentals
The DC link voltage actual value sensing is tested.
Test procedure
1. The DC link is charged up to the rated voltage.
2. The actual value sensing devices in the drive measure the voltage.
Result
The test is passed if the displayed value at the test station computer matches the reference
value.
3.2.7

Switching thresholds of the optional temperature evaluation device

Fundamentals
The switching thresholds of the temperature monitoring function are checked.
Test procedure
1. The auxiliary voltage is present.
2. The switching thresholds at the temperature sensor inputs are triggered.
Result
The test is passed if the appropriate messages are displayed on the test station computer. The
tolerance range at the switching thresholds is ±5 K.
3.2.8

Safety shutdown (optional)

Fundamentals
The tests are performed according to IEC 60146-1-1 and IEC 60204-11. The safety shutdown
of the power section is tested according to the category that was ordered.
