Under Device, you set the parameters for the device that are valid across functions.
With Test support, indications issued via communication interfaces are labeled with an additional test bit, if
this is supported by the protocol. With this test bit you can determine whether an indication is generated in a
test and whether all or individual functions of the device are in the test mode. In this manner the reactions
that are necessary in normal operation due to an indication can be suppressed in other devices that receive
these indications. You can also permit, for example, a trip command to close an energized binary output for
test purposes. Siemens recommends deactivating theTest support again after the test phase.
Application and Setting Notes
The major portion of the settings is described in the chapters cited above. After that, the parameters on the
sections Device, Setting change, Spontaneous indication, and Test support are described.
Parameter: Rated frequency
•
Default setting
(_:101) Rated frequency
=
50 Hz
With the
Rated frequency
parameter, you set the rated frequency of the electrical power system.
Parameter: Minimum operate time
•
Default setting
(_:102) Minimum operate time
=
0.00 s
With the
Minimum operate time
parameter, you set the minimum duration for the trip command of the
functions. The trip command is maintained for the set duration.
Parameter: Reserv.time for com.prot.
•
Voreinstellwert
(_:163) Reserv.time for com.prot.
=
120 s
With the parameter
Reserv.time for com.prot.
, you define the maximum reservation time for the
parameterization of the device via the communication protocol. That means, the maximum time that may
elapse between the beginning of the parameterizing operation (selection of the settings group to be edited)
and the end (confirmation) is the time
Reserv.time for com.prot.
. Otherwise, the parameterization
operation is canceled with a time-out and changes are rejected. This setting value is valid only for the device.
Parameter: Block monitoring dir.
•
Default setting
(_:138) Block monitoring dir.
=
off
With the
Block monitoring dir.
parameter, you set whether indications are output via the system inter-
face(s) of the SIPROTEC 5 device or not.
If transmission blocking is switched on, no indications are output via the system interface(s) of a SIPROTEC 5
device.
Parameter: Fault-display
•
Default setting (_:139) Fault-display =
with pickup
With the
Fault-display
parameter, you set whether spontaneous indications which are signed as
NT
(conditioned latching)
in the matrix, get stored with every pickup or only when the fault was termi-
nated by tripping.
Keep the DIGSI 5 routing options in chapters
3.1.7 Spontaneous Indication Display in DIGSI 5 and Table 3-8 in
mind.
Parameter: Activate device test mode
•
Default setting
(_:150) Activate device test mode
= inactive
