3.4.4.3 Binary outputs and LEDs
In configuration A, signals are routed to binary outputs and LEDs are configured by
OSWGAPC. The 16 OSWGAPC instances are categorized in four groups, including
two master trip, four start, four trip and six alarm signals. The OSWGAPC output is
connected with binary outputs and LEDs via SELGAPC3 and SELGAPC4.
• SELGAPC3 is used to configure OSWGAPC signals to the protection relay's
binary outputs. SELGAPC4 is used to configure OSWGAPC signals to LEDs.
• OSWGAPC1 and OSWGAPC2 are used for the Master trip. The inputs are routed
from the protection function's operate and the circuit breaker failure's re-trip.
• OSWGAPC3 to OSWGAPC6 are used for the start signal. The inputs are start
signals routed from the protection functions.
• OSWGAPC7 to OSWGAPC10 are used for the trip signal. The inputs are
operation signals routed from the protection functions.
• OSWGAPC11 to OSWGAPC16 are used for the alarm signal. The inputs are
alarm signals routed from the protection and monitoring functions.
