10.2.32 Supervision of disconnector contacts (DS fail)
Detecting the operation failure in the disconnector (DS) is achieved by the operation of the
protection common function (PROT_COMM†). Thus, the failure signal in the PROT_COMM is
transferred to the automatic supervision function and it is grouped into the error level together
with other error signals.
†Note: For more information about the PROT_COMM function, see Chapter
application: Protection common
Error level
(i)
Generally, the default error level has been set at level 3 (Minor error), but the user can program
the level using settings [CHK_DS:LVl]; then, set On for the setting [CHK_DS:Sw]. The time for
the detection can be set using [TDSSV], which is provided in the PROT_COMM function. It is
reset instantly when the error is cleared.
Error message
(ii)
When the function operates and detects error, an error message can be shown at the LED and
the LCD screen.
