Note 1 - Range and input type, indication, totalization parameters, relay usage as alarms
and alarm setpoints are, among other things, items that the user can program through
the front panel keys (if wanted, specify such information so that all the configuration can
be made by PRESYS).

Note 2 - Other hardware and software features can be available under previous consult.
