6.5.4 Selection of parameter sets --- address block 85
Up to 4 different sets of parameters can be selected
for the functional parameters, i.e. the addresses
above 1000 and below 4000. These parameter sets
can be switched over during operation, locally using
the operator panel or via the operating interface us-
ing a personal computer, or also remotely using
binary inputs.
The first parameter set is identified as set A, the other
sets are B, C and D. Each of these sets has been set
during parameterizing (Section 6.3.1.2) provided
the switch-over facility is used.
6.5.4.1 Read-out of settings of a parameter
set
In order to
look up
the settings of a parameter set
in
the display
it is sufficient to go to any address of the
function parameters (i.e. addresses above 1000 and
below 4000), either by direct addressing using key
DA
, entering the four-figure address code and termi-
nating with enter key
E
, or by paging through the dis-
play with
Ý
or
ß
. You can switch-over to look up a dif-
ferent parameter set, e.g.
--- Press key combination
F 2
, i.e. first the function
key
F
and then the number key
2
. All displayed
parameters now refer to parameter set B.
The parameter set is indicated in the display by a
leading character (A to D) before the address num-
ber indicating the parameter set identification.
The corresponding procedure is used for the other
parameter sets:
D
Key combination
F 1
:
access to parameter set
A
D
Key combination
F 2
:
access to parameter set
B
D
Key combination
F 3
:
access to parameter set
C
D
Key combination
F 4
:
access to parameter set
D
The relay always operates with the active parameter
set even during read-out of the parameters of any
desired parameter set. The change-over procedure
described here is, therefore, only valid for
read-out
of parameters
in the display
.
6.5.4.2 Change-over of the active parameter
set from the operating panel
For
change over to a different parameter set
, i.e. if
a different set shall be activated, the address block
85 has to be used. For this, codeword entry is re-
quired.
The block for processing parameter sets is reached
by pressing the direct address key
DA
followed by
the address
8 5 0 0
and enter key
E
or by paging
through the display with
Ý
or
ß
. The heading of the
block will appear:
8 5 0 0
P A R A M E T E R
C H A N G E - O V E R
Beginning of the block ”Parameter change-over”:
processing of parameter sets
It is possible to scroll through the individual address-
es using the
"
key or to scroll backwards with
#
.
Address 8501 shows the actually active parameter
set with which the relay operates.
In order to switch-over to a different parameter set
scroll on with
"
to address 8503. Using the
”No”---key
N
you can change to any desired param-
eter set; alternatively, you can decide that the pa-
rameter sets are to be switched over from binary in-
puts. If the desired set or possibility appears in the
display, press the enter key
E
.
As with every settings of the device for which code-
word input is necessary, codeword operation must
be terminated. This is done by using the key combi-
nation
F E
, i.e. depressing the function key
F
fol-
lowed by the entry key
E
. The display shows the
question ”SAVE NEW SETTINGS?”. Confirm with
the ”Yes”---key
Y
that the new settings shall become
valid now. If you press the ”No”---key
N
instead,
codeword operation will be aborted, i.e. all alter-
ations which have been changed since the last
codeword entry are lost. Thus, erroneous alterations
can be made ineffective.
