Annunciation

Tagging equipment from the operator control panel

If the breaker/switch position is not available from the switch-gear, the status of the

switchgear device can be manually set to the actual present position using the opera-

tor control panel: Main Menu → Control → Breaker/Switch → Man. Over-

write. The simulated switching status is used for interlocking checks, and for auto-

matically initiated switching operations.

For convenience during commissioning or at other times, decoupling of the informa-

tion exchange between the switchgear and the protective device may be desired for a

short period, without disconnecting the wires. This function is activated using the op-

erator control panel: Main Menu → Control → Breaker/Switch → Set Status.

To identify unusual operating conditions in the power system, tagging can be done.

The tagging can, for example, be entered as additional operating conditions in inter-

locking checks, which are set up with CFC. Tagging is configured in the same way as

for operating devices.

• The status of the tagging is displayed on the operating panel, Main Menu → Con-

trol → Tagging → Display (Figure 4-11),
