If one tries to leave the setting range for the function-
al parameter blocks (i.e. address blocks 10 to 39)
with keys
Ý ß
, the display shows the question ”END
OF CODEWORD OPERATION ?”. Press the ”No”---
key
N
to continue parameterizing. 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 above.
After completion of the parameterizing process, the
changed parameters which so far have only been
stored in volatile memory, are then permanently
stored in EEPROMs. The display confirms ”NEW
SETTINGS SAVED”. After pressing the key
M/S
fol-
lowed by
RESET LED
, the indications of the quies-
cent state appear in the display.
6.3.1.2 Selectable parameter sets
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.
If this facility is not used then it is sufficient to set the
parameters for the preselected set. The rest of this
section is of no importance. Otherwise, the parame-
ter change-over facility must be configured as
EXIST
under address 7885 (refer Section 5.4.2). The first
parameter set is identified as set A, the other sets are
B, C and D. Each of these sets is adjusted one after
the other.
If the switch-over facility is to be used, first set all pa-
rameters for the normal status of parameter set A.
Then switch over to parameter set B:
--- Fist complete the parameterizing procedure for
set A as described in Section 6.3.1.1.
--- Press key combination
F 2
, i.e. first the function
key
F
and then the number key
2
. All following in-
puts then refer to parameter set B.
All parameter sets can be accessed in a similar man-
ner:

Input of the codeword is again necessary for the set-
ting of a new selected parameter set. Without input
of the codeword, the settings can only be read but
not modified.
Since only a few parameters will be different in most
applications, it is possible to copy previously stored
parameter sets into another parameter set.
It is additionally possible to select the original set-
tings, i.e. the settings preset on delivery, for a modi-
fied and stored parameter set. This is done by copy-
ing the ”ORIG.SET” to the desired parameter set.
It is finally still possible to define the active parameter
set, i.e. the parameter set which is valid for the func-
tions and threshold values of the unit. See Section
6.5.4 for more details.
The parameter sets are processed in address block
85. The most simple manner to come to this block is
using direct addressing:
--- press direct address key
DA
,
--- enter address, e.g.
8 5 0 0
,
--- press enter key
E
.
The heading of the block for processing the parame-
ter sets then appears.
It is possible to scroll through the individual address-
es using the
"
key. The copying facilities are summa-
rized in Table 6.1.
