End Of Line test system
The final assembled frequency converter is fed to a high-voltage test station on a workpiece carrier via a belt transport system. The device under test, including the workpiece carrier, is lifted and taken over by the test station. Subsequent test specimens can thus pass this station and drive to a free station.
After the high-voltage test has been carried out, the test object is placed back on the transport system and transported to one of the eight end-of-line test stations. Here, the test object is taken over equally by the test station that subsequent test objects can overtake.
Each high-voltage and each EOL test station is designed in such a way that each of the 28 device variants can be tested using movable contact heads.
