Internal signal

The internal signal group is used to configure the logic connections between function
blocks. There is one SELGAPC in this group.
SELGAPC2 is used to configure trip circuit supervision blocking from the circuit
breaker open or close position.

SELGAPC2
SELGAPC2 inputs are circuit breaker closed and open positions from SELGACP1.
SELGAPC2 outputs are routed to the BLOCK input of the trip circuit supervision
TCSSCBR1 and TCSSCBR2.
By default, X100-PO3 and PO4 are both used for the open circuit breaker.
TCSSCBR1 and TCSSCBR2 are both blocked by the circuit breaker open position. If
X100-PO3 is used for closing the circuit breaker, TCSSCBR1 needs to be blocked by
the circuit breaker close position (OUT_1 connection=IN_1). If X100-PO4 is used
for closing the circuit breaker, TCSSCBR2 needs to be blocked by the circuit breaker
close position (OUT_2 connection=IN_1).

Binary outputs and LEDs

In configuration A, the signals route to binary outputs and LEDs are configured by
OSWGAPCs. There are totally 15 OSWGAPC instances. They can be categorized to
four groups, including one master trip, four start, four trip and six alarm signals. The
OSWGAPC output is connected to binary outputs and LEDs via SELGAPC3 and
SELGAPC4.
• SELGAPC3 is used to configure OSWGAPC signals to protection relay binary
outputs. SELGAPC4 is used to configure OSWGAPC signals to LEDs.
• OSWGAPC1 is used for master trip. The inputs are the operate and re-trip signals
from protection and breaker failure functions respectively.
• OSWGAPC2 is not in used.
