Description
The signal is routed as active with voltage.
The signal is routed as active without voltage.
The signal is routed as unlatched. Activation and reset of
the output (LED, BA) occurs automatically via the binary-
signal value.
The binary signal is latched when the output (LED) is acti-
vated. To reset, a targeted confirmation must occur.
Fault indications are stored during control of the output
(LED) as a function of the parameter (_:91:139)
Fault-display. In the event of a new fault, the previ-
ously stored states are reset.
•
If the fault gets terminated via a trip command from
the assigned circuit breaker, the status of an indication
remains as latched with the setting option with
trip. Without a trip command, the status is displayed
before the fault (if necessary, the status of the last
fault) is restored.
•
With the setting option with pickup the current
indication image of a pickup gets stored. The image
comprises all indications of functions that are effective
in the event of tripping on the same circuit breaker,
like the picked up function.
The following applies to the busbar protection:
•
If the fault gets terminated via a trip command, the
status of an indication remains as latched with the
setting option with trip.
This occurs separately for the following tripping cases:
– Trippings caused by busbar protection (busbar
differential protection, busbar tripping following
a circuit-breaker failure protection trip in the bay
or busbar tripping due to external tripping)
– Trippings caused by functions within the corre-
sponding bay (for example, end-fault protection,
circuit-breaker failure protection trip repeat or
overcurrent protection)
•
With the setting option with pickup, the current
indication image is saved using the same rules as with
the setting with trip but together with the pickup
of the protection function.
Routing option TL (tripping stored) is only possible for the
switching object circuit breaker.
The output is saved with protection tripping. The contact
remains activated until acknowledged.
Control commands are not affected. A control command is
pending above the parameterized command period until
feedback has been successfully received.
Note:
You can realize the functionality of the Lockout (ANSI 86)
by storing the output relay with the routing option TL.
