Binary Outputs
Overview of Functions
7SR5 devices include a number of binary output functions:
•
Binary outputs (number dependent on hardware configuration)
•
20 Virtual inputs/outputs
•
Fascia LEDs
•
General pickup outputs
•
Trip config outputs
Binary outputs consist of output relays (user specified number), 28 indication LEDs and 28 virtual input/
outputs.
Any function element in the
Output Matrix
can be selected to operate any output relay, LED or virtual
input/output.
Functions that initiate operation of each binary output are defined in the
Configuration > Binary
Outputs
menu. All outputs are fully user configurable and can be programmed to operate from any or all of
the available functions.
Structure of the Function
The operating parameters for each binary output are defined in the
Binary Output Config
menu.
This function corresponds to the logical node
CTRL BOGGIO
in IEC 61850
Each binary output relay can be user programmed to have hand or self-reset operation. Hand reset outputs
can be reset either by:
•
Pressing the fascia ▶ button for ≥ 3 seconds when the
Home Screen
is displayed
•
Operating a suitably programmed binary input
•
Sending an appropriate command over the data communication channel(s).
On loss of the auxiliary supply hand-reset output relays will reset. When the auxiliary supply is reconnected the
output relays will remain in the reset state unless the initiating condition is still present.
The status of virtual inputs/outputs is volatile i.e. is not stored during power loss.
The operating parameters for each LED are defined in the
LED Config
menu.
This function corresponds to the logical node
CTRL LGGIO
in IEC 61850
Each LED can be programmed to be illuminated as either green, yellow or red. Where an LED is programmed
to be lit both red and green it will illuminate yellow. The same LED can be assigned 2 different colors
dependent upon whether a
Pickup
or
Operate
condition exists.
Each LED can be labeled by opening the LED label door and inserting the required label strip into the fascia
recess. A template is available in the Reydisp software tool to allow users to create and print customized
legends.
Each LED can be user programmed to have hand or self–reset operation. Hand reset LEDs can be reset either
by:
•
Pressing the fascia ▶ button for ≥ 3 seconds when the
Home Screen
is displayed
•
Operating a suitably programmed binary input
•
Sending an appropriate command over the data communication channel(s).
The status of hand reset LEDs (non self-reset LEDs) is maintained by a back up storage capacitor in the event of
an interruption to the auxiliary supply.
The
General Pickup
menu is used to select the relay functions that provide a pickup output e.g. to initiate
a separate pickup LED.
