Select. NO/NC. It defines if the input must be interpreted
like active when it is viewed closed or when it is viewed
open. If it is defined as NO, when the input is open the sign
is 0 and when it is closed 1 (for logic inputs). If it is defined
as NC, when the input is open the sign is 1 and when it is
closed 0 (for logic inputs).
For example, for the status of the circuit breaker, if we use a
contact 52 a we should program the corresponding input as
NO (when it closes it indicates closed circuit breaker), while
if we use a 52 b we should program it as NC (when it opens
it indicates closed circuit breaker).
T.activ.inputs (time of activation of inputs). It is a software
filter for the activation/deactivation of digital inputs. The
HW filters is of 1 ms, and it can be extended by Software
in the number of programmed milliseconds (range 0 to
20 ms).
The programming of logical inputs is as follows:
By console, it is carried out on the screen “digital inputs
configuration”, in the lower square of the two located on
the right.
By keyboard/display:
PROG. TABLE 0 - PROG.CONFIG – CONFIG. INPUTS – LOGICAL
INPUTS SELECT. N0/NC
A logical input is a virtual (not physical), the state of which
depends on the state of the corresponding logical input
(input 1 corresponds to signal 1, input 15 to signal 15).
Its function is the one that has been programmed (the
programming possibilities are the same as for the digital
inputs).
This procedure allows the assignation of the relay internal
signals to those inputs as if they were wired field signals. Up
to 15 logical inputs are permitted (there are only 15 logical
signals).
NO/NC selection, input active when the logic is active or
inactive.
Delay is not applied to the activation.
Example: If programming logical input 3 as “breaker status”
and NO, the unit will consider that the breaker will be closed
when logical input 3 is active.
A certain function must be only programmed as one
input. It is not possible, for example, programming “breaker
state” as digital input and as logical input.
3.2. Programming of digital outputs
By console it is carried out in the screen “Digital outputs
configuration”
By keyboard/display:
PROG. TABLE 0 - PROG.CONFIG – PROG. OUTPUTS
OUTPUT ACTIV. T
The functionality of each digital output can be programmed
like an OR of the logical signals available in this unit (see
point “List of available signals”, Appendix III).
In the programming through console (recommended), for
each digital output it is clicked with the mouse in the cells
corresponding to the signs whose OR wants to be activated
by the output (dot-matrix programming).
In the programming screen, at the beginning of the list of
available signals, a line appears with the title “OUTPUT TYPE”
which defines for each digital output if it is of the type “trip”,
“close” “memorized” or “nothing”. If it is of the type “trip” the
output carries out the sealing logic (if the sealing setting
is set to YES) and that of opening failure. If it is of the type
“close” the output carries out the sealing logic (if the sealing
setting is set to YES) and that of close failure. If the type is
“memorized”, once activated it is deactivated digital input
actuation programmed as “local reposition” command or
keyboard/display (“recognize fault”). If the type is “nothing”
it does not do anything special.
The time of activation of outputs defines the minimum
time of operation of each physical output once it has been
activated (in seconds). The range is 0.05 to 5 s. It appears in
the last line of the screen.
By keyboard/display is more complicated. In PROG.SALIDAS,
we find for each one of them with “ASIGN SIGNALS”, with the
following possibilities.
No signal (the output remains without assigning, but it can
be activated by control commands).
Same signals (it is not wished to change the current
programming).
Other signals (it is wished to change the current
programming). When pushing “
↵
” (Intro), it is gone through
the logical signals with the arrow
↓
; when we arrive to a
signal that we want to use in the OR that defines the output
we press “R”; when we finish with the signals, we pulse “
↵
”,
which takes us to the programming of the output type, with
the possibilities already indicated.
