Setting the functional parameters
6.3.1. Introduction
6.3.1.1
Parameterizing procedure
For setting the functional parameters it is necessary
to enter the codeword (see 5.3.1). Without code-
word entry, parameters can be read out but not be
changed.
If the codeword is accepted, parameterizing can be-
gin. In the following sections each address is illus-
trated in a box and is explained. There are three
forms of display:
--- Addresses without request for operator input
The address is identified by the block number fol-
lowed by 00 as sequence number (e.g. 1100 for
block 11). Displayed text forms the heading of this
block. No input is expected. By using keys Ý or ß
the next or the previous block can be selected. By
using the keys " or # the first or last address within
the block can be selected and paged.
--- Addresses which require numerical input
The display shows the four-digit address, i.e.
block and sequence number (e.g. 1105 for block
11, sequence number 5). Behind the bar appears
the meaning of the required parameter, in the sec-
ond display line, the value of the parameter. When
the relay is delivered a value has been preset. In
the following sections, this value is shown. If this
value is to be retained, no other input is neces-
sary. One can page forwards or backwards within
the block or to the next (or previous) block. If the
value needs to be altered, it can be overwritten us-
ing the numerical keys and, if required, the deci-
mal point and/or change sign (+/--- ) or, where ap-
propriate, infinity sign 1. The permissible setting
range is given in the following text, next to the as-
sociated box. Entered values beyond this range
will be rejected. The setting steps correspond to
the last decimal place as shown in the setting box.
Inputs with more decimal places than permitted
will be truncated down to the permissible number.
The value must be confirmed with the entry key
E! The display then confirms the accepted value.
The changed parameters are only saved after ter-
mination of parameterizing (refer below).

--- Addresses which require text input
The display shows the four-digit address, i.e.
block and sequence number (e.g. 1201 for block
12, sequence number 1). Behind the bar appears
the meaning of the required parameter, in the sec-
ond display line, the applicable text. When the
relay is delivered, a text has been preset. In the
following sections, this text is shown. If it is to be
retained, no other input is necessary. One can
page forwards or backwards within the block or to
the next (or previous) block. If the text needs to be
altered, press the "No" key N. The next alternative
text, also printed in the display boxes illustrated in
the following sections, then appears. If the alter-
native text is not desired, the N key is pressed
again, etc. The alternative which is chosen, is
confirmed with the entry key E. The changed
parameters are only saved after termination of pa-
rameterizing (refer below).
For each of the addresses, the possible parameters
and text are given in the following sections. If the
meaning of a parameter is not clear, it is usually best
to leave it at the factory setting. The arrows Ýß or "#
at the left hand side of the illustrated display boxes
indicate the method of moving from block to block or
within the block. Unused addresses are automati-
cally passed over.
If the parameter address is known, then direct ad-
dressing is possible. This is achieved by depressing
key DA followed by the four-digit address and sub-
sequently pressing the enter key E. After direct ad-
dressing, paging by means of keys Ý ß and keys " #
is possible.
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.
