Application manual
The trip function (SMPPTRC) splits up the directional data as general output data for
BFI_3P, BFI_A, BFI_B, BFI_C, FW and REV.
All start and directional outputs are mapped to the logical node data model of the trip
function and provided via the 61850 dirGeneral, DIRL1, DIRL2, DIRL3.
ACT naming and description:
• SMAGAPC for Start Matrix function
• SMPPTRC for Trip function
• STARTCOMB for Start Combination function (Boolean to Word)

Blocking of the function block

Total block of the trip function is done by activating the input BLOCK and can be used to
disable the outputs of the trip logic in the event of internal failures. Block of lock-out
output is achieved by activating the input BLKLKOUT.
Setting guidelines
The parameters for tripping logic SMPPTRC (94) are set via the local HMI or PCM600.
The following trip parameters can be set to regulate tripping.
Operation: Sets the mode of operation. Disabled switches the tripping off. The normal
selection is Enabled.
Program: Sets the required tripping scheme. Normally 3 phase or 1p/3p is used.
TripLockout: Sets the scheme for lock-out. Disabled only activates the closing circuit
lock-out output. Enabled activates the closing circuit lock-out output and latches the TRIP
related outputs. The normal selection is Disabled.
AutoLock: Sets the scheme for lock-out. Disabled only activates lock-out through the
input SETLKOUT. Enabled additionally allows lock-out activation via the trip inputs.
The normal selection is Disabled.
tTripMin: Sets the required minimum duration of the trip pulse. It should be set to ensure
that the breaker is opened correctly. The normal setting is 0.150s.
tWaitForPHS: Sets a duration after any of the inputs 1PTRZ or 1PTRGF has been
activated during which external pole selection must operate in order to get a single pole
trip. If no pole selection has been achieved, a three-pole trip will be issued after this time
has elapsed.
