Tagging equipment from the operator control panel

C53000-G1176-C133-1

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: 0DLQ 0HQX → &RQWURO → %UHDNHU6ZLWFK → 0DQ 2YHU

ZULWH. 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: 0DLQ 0HQX → &RQWURO → %UHDNHU6ZLWFK → 6HW 6WDWXV.

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, 0DLQ 0HQX → &RQ
