Figure 47: Master trip
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.
There are three disconnector status blocks (DCSXSWI1…3) available in the IED.
The remaining two not described in the functional diagram are available in SMT for
connection where applicable.
