5.5.2 Marshalling of the binary inputs --- address block 61
The unit contains 10 binary inputs which are desig-
nated INPUT 1 to INPUT 10. Input s 1 to 9 can be
marshalled in address block 61. The address block
is reached by paging in blocks
Ýß
or by direct ad-
dressing with
DA 6 1 0 0 E
. The selection proce-
dure is carried out as described in Section 5.5.1.
A choice can be made for each individual input func-
tion as to whether the desired function should be-
come operative in the ”normally open” mode or in
the ”normally closed” mode, whereby:
NO
--- ”normally open” mode: the input acts as a NO
contact, i.e. the control voltage at the input
terminals activates the function;
NC
--- ”normally closed” mode: the input acts as a
NC contact, i.e. control voltage present at the
terminals turns off the function, control volt-
age absent activates the function.
When paging through the display, each input func-
tion is displayed with the index ”
NO
” or ”
NC
” when
proceeding with the ”No”---key
N
.
Table 5.1 shows a complete list of all the binary input
functions with their associated function number
FNo
. Input functions naturally have no effect if the
corresponding protection function is not fitted in the
relay or has been programmed out (”de-config-
ured”, refer Section 5.4.2).
With direct input of the function number, leading zer-
os need not be used. To indicate the contact mode
the function number can be extended by a decimal
point followed by
0
or
1
, whereby
.0
means ”normally open” mode, corresponds to
”
NO
” as above.
.1
means ”normally closed” mode, corresponds to
”
NC
” as above.
If the extension with .0 or .1 is omitted the display first
indicates the function designation in ”normally
open” mode
NO
. By pressing the ”No”---key
N
the
mode is changed to
NC
. After direct input other func-
tions can be selected by paging through the func-
tions forwards with the ”No”---key
N
or backwards
with the backspace key
R
. The changed function
then must be re-confirmed by the entry key
E
.
Note:
Binary input 10 is reserved exclusively for the
general fault detection signal of the main protection
relay. If the main protection relay does not output a
fault detection (start or pick-up) signal, the trip com-
mand must be repeated to this input. The allocation
of this input cannot be changed.
Attention! The
binary inputs 8 to 10 are included in the trip re-
lease concept of the protection device (refer Sec-
tion 4.2.7 for explanations). The allocation of
binary inputs 8 and 9 should not be changed un-
less this concept is comprehensively clear, and
only in harmony with this concept.
The assignment of the binary inputs as delivered
from factory is shown in the general diagrams in Ap-
pendix A. The following boxes show, as an example,
the allocation for binary input 1. Table 5.2 shows all
binary inputs as preset from the factory.
