Depending on the selected function, the unit's user interface adapts itself, so that each
time only parameters that are required for safe unit functioning have to be checked/set.
The following functions are available:
"Switched Off": digital input is not active.
"Control Input": various control functions can be activated using the digital input.
"On/Off Event": switch conditions of connected units (e.g. pump on/off) are displayed
and stored.
"Pulse Counter": pulses are added up and stored as numeric counter values.
"Operational Time": running times of external units are recorded e.g. for maintenance
purposes.
Example: if the daily running time of a pump is to be saved, activate "Operational Time"
here and "Daily Analysis" under "Signal Analysis".
"Event+Operation Time":
both the on/off events and the operating time of an external unit are recorded and
stored.
