Plug-in test systems – the right solution to every task

Comparison of plug-in test systems

Forced switching sequence of the FAME 2 and FAME RACK plug-in test systems in just one block

The plug-in test systems use two different approaches in order 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 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, thereby 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, FAME 3, and FAME 3 SL plug-in test systems combine the switching process sequences in different blocks, which means that a forced switching sequence is not necessary.

Automatic leading transformer short circuit

The FAME plug-in test systems can be short circuited quickly and easily in the event of a relay test or to replace a protective device. To do so, depending on the system, short circuit the current transformer with standard plug-in bridges in the plug-in test socket or in the test plug. This results in an easily induced leading signal separation.

Rotary handle mechanism for the FAME 2, FAME 3, and FAME RACK plug-in test systems

The patented rotary handle mechanism of the plug-in test systems helps you evenly pull the test plug out of the test block. The forced locking and the short-term pause in the various switch positions associated with it allow the plug-in test system to have the highest degree of safety for both system and operator.

As soon as you have completely inserted the test plug, the plug will lock securely into the plug-in test socket. All test contacts are contacted in accordance with the test setup. You can unlatch the test plug by rotating the handle through 45° as far as it will go. This allows you to pull the plug out up to the intermediate stage. The plug-in test system current transformer contacts are reconnected with the protective device. The plug is only unlatched when the rotary handle springs back into the starting position. Then you can pull the test plug out of the plug-in test system completely. The original signal connections are restored.

Locking mechanism of the FAME 3 SL plug-in test system

The test plug of the FAME 3 SL plug-in test system locks automatically into the plug-in test socket when it is plugged in. The test contacts are securely contacted in accordance with the test setup. After the test is over, you can release the latching by actuating the orange lever. Unplugging the test plug will restore the plug-in test system’s original signal connections.

Mounting type of the plug-in test systems

The different plug-in test systems can be installed in different ways.

The FAME RACK plug-in test system is screwed into a 19-inch mounting frame using screws. Thanks to the modularity of the FAME 3 rack system, plug-in test sockets with two rack units and up to seven positions, three rack units with up to 12 positions, and four rack units with up to 18 positions can be replicated. You also have the option of mounting the FAME RACK plug-in test system directly in cutouts in front plates or control cabinet doors outside of the 19-inch format.

The FAME 3 SL plug-in test system, in contrast, was designed exclusively for panel cutouts. The system uses two push buttons, which allows the plug-in test system to be latched into an appropriate cutout quickly and easily.

The FAME 1, FAME 2, and FAME 3 systems are likewise installed in cutouts in front plates or control cabinet doors. In this case, the plug-in test sockets are secured in the cutouts by means of a patented screw mechanism.

Safe cable routing for plug-in test sockets

For control and operating purposes, plug-in test systems should usually be accessible from the outside. This is why some devices and plug-in test sockets are mounted in the control cabinet door in protection and control engineering applications.

The swivel arm of the cable guiding system makes it particularly easy and safe to install your conductors, cables, and cable harnesses for the control cabinet door or swivel mounting frame. This solution saves time, as the patent-pending swivel joints can be opened and pre-assembled cables can be fed through or pulled through without using any tools.
