Application manual

VSGAPC can be used for both acquiring an external switch position (through the IPOS1

and the IPOS2 inputs) and represent it through the single line diagram symbols (or use it

in the configuration through the outputs POS1 and POS2) as well as, a command function

(controlled by the PSTO input), giving switching commands through the CMDPOS12 and

CMDPOS21 outputs.

The output POSITION is an integer output, showing the actual position as an integer

number 0 – 3, where 0 = MidPos, 1 = Open, 2 = Closed and 3 = Error.

An example where VSGAPC is configured to switch Autorecloser enabled–disabled from

a button symbol on the local HMI is shown in figure363. The Close and Open buttons on

the local HMI are normally used for enable–disable operations of the circuit breaker.

Control of Autorecloser from local HMI through Selector mini switch

VSGAPC is also provided with IEC 61850 communication so it can be controlled from SA

system as well.

Setting guidelines

Selector mini switch (VSGAPC) function can generate pulsed or steady commands (by

setting the Mode parameter). When pulsed commands are generated, the length of the

pulse can be set using the tPulse parameter. Also, being accessible on the single line

diagram (SLD), this function block has two control modes (settable through CtlModel):

Dir Norm and SBO Enh.
