6.3 Setting the functional parameters
6.3.1. Introduction
6.3.1.1 Parameterizing procedure
For setting the functional parameters it isnecessary
to enter the codeword (see 5.3.1). Without code-
word entry, parameters can be read out but not be
changed.
Ifthe codeword isaccepted, 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
block11).Displayed textformstheheading ofthis
block. No input is expected. By using keys Ý or ß
the next orthe previous block can be selected. By
using the keys "or# thefirst orlast 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
themeaning oftherequired parameter,in the sec-
ond display line, the value ofthe 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 tobealtered, itcan beoverwritten 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
thelast decimal place asshown inthe setting box.
Inputs with more decimal places than permitted
willbe truncated downtothe permissible number.
The value must be confirmed withtheentrykey
E! The display then confirms the accepted value.
The changed parameters are onlysaved 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
themeaning oftherequired 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 orbackwards withintheblock orto
the next (orprevious) block. Ifthe text needs tobe
altered, press the ”No”key N.The nextalternative
text, also printed inthe 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 areonlysaved aftertermination ofpa-
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, itis 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 ofmovingfromblocktoblockor
within the block. Unused addresses are automati-
cally passed over.
If the parameter address is known, then direct ad-
dressing ispossible. This isachieved 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
thekeycombination FE,i.e.depressing thefunction
key Ffollowed bythe 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 willbe aborted, i.e. all al-
terations which have been changed since the last
codewordentryarelost. Thus, erroneous alterations
can be made ineffective.
