To prevent closing of a circuit breaker after a trip, the function offers a lockout
function.
12.1.2.1 Three-phase tripping
M14828-7 v10
Connect the inputs from the protection functions to the input TRIN. The TMGAPC
function block is used to combine up to 32 inputs into one output. Connect the
output TRIP to the binary outputs on the IO board.
This signal can also be used for other purposes internally in the IED. An example
could be the starting of breaker failure protection. The three outputs TRL1, TRL2,
TRL3 will always be activated at every trip and can be utilized on individual trip
outputs if single-phase operating devices are available on the circuit breaker even
when a three-phase tripping scheme is selected.
Set the function block to Program = 3 phase and set the required length of the trip
pulse to for example, tTripMin = 150ms .
The typical connection is shown below in figure 90 .

12.1.2.2 Single- and/or three-phase tripping
M14828-11 v6
The single-/three-phase tripping operation mode will give single-phase tripping for
single-phase faults and three-phase tripping for multi-phase fault. This operating
mode is always used together with a single-phase autoreclosing scheme.
The single-phase tripping operation mode can include different options and the use
of the different inputs in the function block. Inputs TRINL1, TRINL2 and TRINL3
