Figure 76: Circuit breaker failure protection function
The operate signals from the protection functions are connected to the two trip logics:
TRPPTRC1 and TRPPTRC2. The output of these trip logic functions is available at
binary output X100:PO3 and X100:PO4. The trip logic functions are provided with a
lockout and latching function, event generation and the trip signal duration setting. If
the lockout operation mode is selected, binary input X110:BI1 can be assigned to
RST_LKOUT input of both the trip logic to enable external reset with a push button.
