Technical Manual
The inputs from the protection functions are connected to the OPERATE input.
Usually, a logic block OR is required to combine the different function outputs to this
input. The TRIP output is connected to the binary outputs on the IO board. This signal
can also be used for other purposes within the protection relay, for example when
starting the breaker failure protection.
TRPPTRC is used for simple three-phase tripping applications.
