Configuration of operational functions
5.3.1
Operational preconditions
For most operational functions, the input of a code-
word is necessary. This applies for all entries via the
membrane keyboard or front interface which con-
cern the operation on the relay, for example
--- configuration parameters for operation language,
LSA configuration and device configuration,
--- allocation or marshalling of annunciation signals,
binary inputs, optical indications,
--- setting of functional parameters (thresholds,
functions).

Settings for operating parameters --- address block 70
Operating parameters can be set in address block
70. This block allows the operator language to be
changed. The transmission speed for transfer of
data to a personal computer can be matched to the
interface of the PC, messages on the front display
can be selected here for the quiescent state of the
unit or after a fault event. To change any of these pa-
rameters, codeword entry is necessary.
The simplest way of arriving at the beginning of this
configuration block is to use key DA, followed by the
address number 7 0 0 0 and ENTER, key E. The ad-
dress 7000 appears (see below). Key " will take the
operator to address 7001.
The display shows the four-digit address number,
i.e. block and sequence number. The title of the re-
quested parameter appears behind the bar (see be-
low). The second line of the display shows the text
applicable to the parameter. The present text can be
rejected by the "No"---key N. The next text choice

W R O N G
The codeword is not required for the read-out of an-
nunciations, operating data or fault data, or for the
read-out of setting parameters.
To indicate authorized operator use, press key CW,
enter the six figure code 0 0 0 0 0 0 and confirm
with E. Codeword entry can also be made retro-
spectively after paging or direct addressing to any
setting address.
The entered characters do not appear in the display,
instead only a symbol @ appears. After confirmation of
the correct input with E the display responds with CW
ACCEPTED. Press the entry key E again.
If the codeword is not correct the display shows
CODEWORD WRONG. Pressing the CW key allows
another attempt at codeword entry.
then appears, as shown in the boxes below. The
chosen alternative must be confirmed with enter
key E!
When the relay is delivered from the factory, the de-
vice is programmed to give function names and out-
puts in the German language. This can be changed
under address 7001. The operator languages avail-
able at present are shown in the boxes below.
The setting 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 display shows
the question "SAVE NEW SETTINGS?". Confirm
with the "Yes"---key Y that the new settings shall be-
come valid now. If you press the "No"---key N in-
stead, codeword operation will be aborted, i.e. all al-
terations which have been changed since the last
codeword entry are lost. Thus, erroneous alterations
can be made ineffective.
