3.2.6.14 Tripping logic TRPPTRC
Tripping logic has been configured to provide tripping signal of required duration
to Master trip 1 and Master trip 2 circuit. The tripping circuit opens the circuit
breaker on
• Receipt of operate signal from the protection function or
• Retrip signal from circuit breaker failure protection.
Two master tripping signals are available at binary output PSM PO1 and PSM
PO3. The lockout reset binary input available at COM BI10 is connected to the
tripping circuit to reset the circuit-breaker lockout function.

3.2.6.15 Combined operate and start alarm signal
The operate outputs of all protection functions are combined in an OR-gate to get a
common Operate output. This common operate signal is connected to a tripping
logic. It is also available as an alarm binary output, PSM SO1, with a settable
minimum alarm delay of 80 ms. Also, a common Start output is derived from the
start outputs of protection functions combined in an OR-gate. The output is
available as an alarm binary output PSM SO2 with a settable minimum alarm delay
of 80 ms.
