Configuration of the device functions
5.4.1 Introduction
The
device
7SV512 is capable of providing a series
of
functions
. The scope of the hard- and firm-ware is
matched to these functions. Furthermore, individual
functions can be set (configured) to be effective or
non-effective or the interaction of the functions can
be modified by configuration parameters. Addition-
ally, the relay can be adapted to the system frequen-
cy.
The configuration parameters are input through the
integrated operation keyboard at the front of the de-
vice or by means of a personal computer, connected
to this front-interface. The use of the integrated oper-
ating keyboard is described in detail in Section 6.2.
Alteration of the programmed parameters requires
the input of the codeword (see Section 5.3.1). With-
out codeword, the setting can be read out but not al-
tered.
For the purpose of configuration, addresses 78
KK
are provided. One can access the beginning of the
configuration blocks either by direct dial
--- press direct address key
DA
,
--- type in address
7 8 0 0
,
--- press execute key
E
;
or by paging with the keys
Ý
(forwards) or
ß
(back-
wards), until address 7800 appears.
Within the bock 78 one can page forward with
"
or
back with
#
. Each paging action leads to a further
address for the input of a configuration parameter. In
the following sections, each address is shown in a
box and explained. In the upper line of the display,
behind the number and the bar, stands the asso-
ciated device function. In the second line is the asso-
ciated text (e.g. ”
EXIST
”). If this text is appropriate
the arrow keys
"
or
#
can be used to page the next
address. If the text should be altered press the
”No”---key
N
; an alternative text then appears (e.g.
”
NON---EXIST
”). There may be other alternatives
which can then be displayed by repeated depres-
sion of the ”No”---key
N
. The required alternative
must be confirmed with the key E!
The configuration procedure can be ended at any
time by the key combination
F E
, i.e. depressing the
function key
F
followed by the entry key
E
. The dis-
play shows the question ”SAVE NEW SETTINGS ?”.
Confirm with the ”Yes”---key
J/Y
that the new set-
tings shall become valid now. If you press the
”No”---key
N
instead, codeword operation will be
aborted, i.e. all alterations which have been
changed since the last codeword entry are lost.
Thus, erroneous alterations can be made ineffec-
tive.
If one tries to leave the setting range for the configu-
ration blocks (i.e. address blocks 60 to 79) with keys
Ý ß
, the display shows the question ”END OF CODE-
WORD OPERATION ?”. Press the ”No”---key
N
to
continue configuration. If you press the ”Yes”---key
J/Y
instead, another question appears: ”SAVE NEW
SETTINGS ?”. Now you can confirm with
J/Y
or
abort with
N
, as described above.
When one exits the setting program, the altered pa-
rameters, which until then have been stored in vola-
tile memories, are then permanently secured in
EEPROMs and protected against power outage.
The processor system will reset and re-start. During
re-start the device is not operational.
