Selection Preset 1 / Preset 2
LYNX 4400 units have two detection levels, called Preset 1 and Preset 2.
Preset 1 corresponds to the greatest earth fault detection sensitivity. This position is used
preferentially.
The Preset 2 position is intended for special cases, such as when most of the detectors used
for the outputs are older-generation detectors (pre-2009).
