The maximum counting frequency of the digital inputs can be adjusted
using the "enSuite" software. The limit values specified for frequency and
duration shall only apply if the so-called "software debounce" has been
switched off.
The maximum counting frequency is parameterized to 2 Hz
as a default. Changing parameters to f
possible with skilled, qualified staff and when administrator
or calibration lock is open. Changes to the input frequency
must be documented by the operator of the device.
If the software debounce is parameterized to a frequency
higher than 2 Hz, then it may lead to counting errors
caused by electromagnetic interference under certain
circumstances.
