Information about the State of Inputs/Outputs and Active LEDs
The screens of Digital Inputs, Digital Outputs,
Protection Inputs and Protection LEDs are
configurable and, therefore, will vary for each
model.
The maximum number of signals that a screen can
represent is 30 and the layout is as in figure 9.5. If
more than 30 signals must be displayed, as in the
case of the alarms, there will be more screens. If,
on the contrary, so many signals are not required,
only those that have been predetermined for the
specific case will be displayed.
Figure 9.5
Display of Active Inputs/Outputs.
If the signals are active, they are represented by a full rectangle (simulating a LED), while the
rectangle will be empty if they are not active. The association of the information to be
represented and each of the rectangles depend on the Configuration loaded in the unit.
In the case of the screens of Digital Outputs, of Protection Inputs and of Protection LEDs, the
layout is the same as in the case of the Inputs, replacing
ED
XX with
SD
XX, with
EP
XX or with
LP
XX respectively, where XX represents the number of the signal. The
EP
XX signals represent
Input Signals to the Control Subsystem sent by the Protection Subsystem. They also vary for
each specific model.
9.3.3
Information about the Indication of Measurements
The measurements represented on the screen also depend on the terminal settings. Figure 9.6
shows a concrete example, where # represents a number.
The first frame always includes the value of the
Current Measurement and the Rated Voltage
values (depending on the Configuration, there can
be one, two, three or four rated voltage values).
The second frame includes the values of the Input
Transducers (which can be values of active,
reactive or calculated power using inputs from
instrument transformers). The third frame displays
the values of the Counters.
On
7IRD-A/J
Models, the last rectangle presents
the number of reclosings produced: the first
number displays those produced counting only the
first of each cycle and the second number displays
the total reclosings minus those accumulated in
the preceding counter.
