5.14 Operation menu

This  menu  allows  the  parameter  setting  of  the  operation  function:  choice  of  the  language,
adjustment  of  LCD  contrast,  parameter  setting  of  the  values  of  the  phase  and  earth-fault
CTs,  display  of  the  digital  input  corresponding  to  set  2,  trip  pulse,  maximum  of  cut  A²  and
number of operations of the circuit breaker, assignment of the relays for circuit breaker failure
and discrepancy, average current.
