Application Manual
Two separate TCS functions have been included: TCSSCBR1 for PO3 (X100:16-19)
and TCSSCBR2 for PO4 (X100:20-23). Both functions are blocked by the Master
Trip and the circuit breaker open position signal. The TCS alarm indication is
connected to LED 9.

Figure 14: Master trip
The operate signals from the protections described above are connected to the two
trip output contacts PO3 (X100:16-19) and PO4 (X100:20-23) via the corresponding
Master Trips TRPPTRC1 and TRPPTRC2. The open control commands to the circuit
breaker from local or remote CBXCBR1-exe_op or from the auto-recloser
DARREC1-open_cb are connected directly to the output PO3 (X100:16-19).
The TRPPTRC1 and 2 blocks provide the lockout/latching function, event generation
and the trip signal duration setting. If the lockout operation mode is selected, one
binary input can be re-assigned to the RST_LKOUT input of the Master Trip to enable
external reset with a push button.
