Automatic synchronisation / limitation of signal strength in the case
of frequent use of the ENS
A “team” of parallel connected ENS units at the same feeding point gen-
erate a joint, stronger test signal through synchronisation. This enables
even higher measuring accuracy. Faulty triggering is practically zero and
operation is more stable.
The parallel connected ENS units generate a “decentral test tone”. As the
number of ENS devices increases, more and more enter a passive operat-
ing state. They only generate a few signals themselves and use the jointly
generated test signal as a pilot tone which can be measured at the mains
power connection point.
