Individual Branch Output Settings Section 4-5
4-5 Individual Branch Output Settings
This section shows the displays and operations when setting parameters in
Setting Mode in protection level 0. If the protection level is set to level 1 or 2,
some parameters will not be displayed or will be read-only. (For details, see
page 54.)
Setting the Abnormal Current Tripping Threshold: C-V (Cutoff Threshold Value)
The initial Setting Mode display (C-V) is used to set the abnormal current trip-
ping threshold. (The branch output that was most recently modified will be the
current branch output regardless of the operating mode.)
Note If the branch output's current exceeds the threshold, the output will be cut off.
The current tripping type is set with the following C-T (cutoff type) display. The
tripping type can be set in protection level 0 only.
After an output is cut off, the seven-segment display will alternately show error
code A11 and the current, and the photoswitch output for Tripping Alarm Out-
put (TRP) will be turned OFF.
The error can be cleared immediately, but the next error cannot be cleared for
another 15 s.
When the Key is pressed, the SV display will flash. When the
flashing stops, the new SV will be saved and the S8AS will return to
C-V display.
If you want to confirm the new setting, press the Key again from
the C-V display.
