7 Settings
7.1 Parameters
The P634 must be adjusted to the system and to the protected equipment by
appropriate settings. This chapter gives instructions for determining the settings,
which are located in the folder titled “Parameters” in the menu tree. The
sequence in which the settings are listed and described in this chapter
corresponds to their sequence in the menu tree.
The P634 devices are supplied with a factory-set standard configuration of
settings that, in most cases, correspond to the default settings or become
apparent after a “cold restart”. The P634 is blocked in that case. All settings
must be re-entered after a cold restart.
Note
Detailed information about all parameters, including complete selection tables and
IEC 60870‑5‑103 protocol properties, are separately available as a set of interlinked
PDF files for user-friendly navigation, packed in one ZIP archive named
DataModelExplorer_P634_en_P01.zip.
In contrast to P634 versions before P634‑630, the implementation of the IEC 61850
protocol now features parameters that cannot be modified from the local control
panel (HMI) or with the operating program. Instead, these parameters are set with
a special IEC 61850 operating software, named “IED Configurator”.
Therefore these settings are not listed in this chapter or the following chapter.
These parameters are described in Chapter “IEC 61850 Settings via IED
Configurator”.
Cancelling a Protection Function
The user can adapt the device to the requirements of a particular high-voltage
system by including the relevant protection functions in the device configuration
and cancelling all others (removing them from the device configuration).
The following conditions must be met before cancelling a protection function:
●
The protection function in question must be disabled.
●
None of the functions of the protection function to be cancelled may be
assigned to a binary input.
●
None of the signals of the protection function may be assigned to a binary
output or an LED indicator.
●
No functions of the device function being cancelled can be selected in a list
setting.
●
None of the signals of the protection function may be linked to other signals
by way of an “m out of n” parameter.
The protection function to which a parameter, a signal, or a measured value
belongs is defined by the function group designation (example: “LIMIT:”).
General Notes on the Configuration of Function Group “Binary Input” (INP)
The P634 has optical coupler inputs for processing binary signals from the
system. The number and connection schemes for the available binary inputs are
shown in the terminal connection diagrams. The “DataModelExplorer” (available
as a separate ZIP archive file) gives information about the configuration options
for all binary inputs.
