Description of the Output Signals
Description
This signal executes all 3-pole tripping and opening oper-
ations.
The Output time parameter affects the signal.
The signal is pending for the duration of this period, with
the following exceptions:
•
Only when switched off by the control: The signal is
canceled before expiration of the period if the auxil-
iary contacts report that the circuit breaker is open
before expiration of the period.
•
Only in the event of protection tripping: The signal
remains active as long as the trip command is still
active after expiration of the period (see also
5.6.4.1 Function Description
•
Only in the event of protection tripping: With the
routing option Only saved in the event of tripping,
the signal remains pending until it is acknowledged
manually. This only applies for protection tripping.
This signal only executes 1-pole tripping for phase A. If 3-
pole tripping occurs while a 1-pole trip signal is active,
the 1-pole signal is canceled.
The signal is active for as long as the trip command is
active, but at least for the duration of the output time.
This signal only executes 1-pole tripping for phase B. If 3-
pole tripping occurs while a 1-pole trip signal is active,
the 1-pole signal is canceled.
The signal is active for as long as the trip command is
active, but at least for the duration of the output time.
This signal only executes 1-pole tripping for phase C. If 3-
pole tripping occurs while a 1-pole trip signal is active,
the 1-pole signal is canceled.
The signal is active for as long as the trip command is
active, but at least for the duration of the output time.
