0 to 1), indicating that the breaker is closed. Activation of VOLTGON clears the calculated residual
fluxes, independent of BLOCKINT.
Once the residual fluxes are reset to the user defined values, the closing angles are recalculated and
updated at the corresponding outputs. The binary output VALIDSTGY is also reset to 1 and INVFLUX
is reset to 0 in this case.

Blocking the TRAFOSWT Function

The operation of TRAFOSWT function can be blocked by activating a binary input BLOCKINT. The
purpose of this input is to block all the outputs of the function (both analog and binary). The priority of
BLOCKINT in relation to other related functionalities can be seen from the list below, wherein the first
item has highest priority.
1. De-energization is in progress, that is, the function is in the process of calculating residual fluxes
and closing angles. This process is executed completely before responding to BLOCKINT input.
2. BLOCKINT input is activated. The residual fluxes, VALIDSTGY, INVFLUX and closing angles
are retained when this input is activated. All the remaining outputs are set to their default values
as a long as this input is active.
3. RESETFLUX is activated.

Functionality

GFGDE is a general interface function for mapping the signals to measurand, breaker and isolator
position, which indicates the symbol in the Graphical Display Editor (GDE) of PCM600 and displays it
in LHMI. This function also supports the real-to-integer and integer-to-real conversion.
