Figure 51: HLT function Logic Scheme
The application of Hot-Line functionality is as shown in the figure below. These logic
schemes are located in the Control Tab. The Auto reclose SDARREC1 (79) function has
HOTLINE_TAG as one of the channels connected to the INHIBIT_RECL input. When
HLT function is activated, it inhibits recloser function and also it negates the
ENA_CLOSE inputs for the SCBXCBR1 (52) function block, thus blocks closing.
This signal can be bypassed by ITL_BYPASS (interlocking bypass, Figure
52) signal, however the default logic does not use the ITL_BYPASS signal.
If the ITL_BYPASS signal were to be used, it is recommended to connect
the HOTLINE_TAG signal to the BLK_CLOSE inputs (Figure 52) which
cannot be bypassed by ITL_BYPASS.
