Digital inputs
4.5.1 Pulse and reporting inputs NF
The maximum meter frequency of the digital inputs can be set with the enSuite software. The
thresholds stated here for frequency and duration apply only if the so-called software debouncing
is deactivated.
Ex works, the software debouncing is activated to suppress fault pulses and so that safe counting
is limited to 2 Hz.
If the software debouncing is set to a higher frequency than 2 Hz, miscounting
from electromagnetic faults may arise under certain circumstances.
