The plug-in test systems use two different approaches in order to be able to perform various switching tasks in the correct forced switching sequence.
The FAME 2 system test plug has three different contact lengths, which allows you to carry out the switching sequence with a safe chronological disconnection with a plugging operation.
The FAME RACK plug-in test system, in contrast, allows the forced switching sequence to happen in the plug-in test socket, which means that the tests can be carried out with just a single plug, saving time. In order to implement the forced switching sequence in the plug-in test socket, the socket is comprised of single plates. When assembling the socket, you therefore can choose between different types of plates with different switching points. The S-plate, for example, has a late switching point and a short distance to the connecting contact. This means that this plate is switched last when plugging in with long delay. Alongside the S-plate, the system has M- and L-plates. M-plates have a delayed switching point, and the L-plates have an early switching point.
The FAME 1, 3 and FAME SL plug-in test systems combine the switching process sequences in different blocks, which means that a forced switching sequence is not necessary.
