FAME 2 – test plugs with patented rotary handle – the functions at a glance:

Defined, mechanically supported removal of the patented test plug from the test block. Optical display and forced locking in the various switch positions.

The test plug is completely inserted and securely engaged. The display window turns red. All test contacts are contacted according to the test setup.

The rotary handle is turned upward as far as it will go. The display window turns yellow. Test contacts with short contact tab lengths (e.g., current transformers) are once again connected to the protective device. The transformer is still short-circuited.

The rotary handle must be turned back to its starting position. The display window turns green. Now the mechanism releases the plug so it can be fully removed. The transformer short circuit is overridden.
