This section of the LCD display shows the Single Line Diagram (SLD) of the
controlled panel and the measurement bars. Text can be added in this section
to improve the understanding of SLD.
*Command buttons
The Primary Object Control can be performed with the following push
buttons to allow operating the primary objects if configured as “selectable”.
The command push buttons for local operation of the switching devices are:
Open: to open the selected object.
Close: to close the selected object.
Select: to select the object. The selected object appears highlighted.
CB Fast Opening: to allow opening of the circuit breaker independently
from the selected control mode. When pressed simultaneously with the
normal open button, this button allows opening the circuit breaker
independently from the selected control mode. This feature must be
enabled in the unit with the Operating Tool.
*E-Keys Sensor: this is the sensor for the electronic keys. The sensor
automatically detects which key has been inserted. The two keys are
usually labelled “Protect”and “Control”to distinguish them.
*Protection key: is specialized to the protection environment allowing
changing of parameters and other functions related to the protection.
*Control Key: this is dedicated to the control modes. It allows changing the
operating mode of REF542plus. The different operating modes discipline
the access to the primary objects by the different REF542plus interfaces
(HMI and SCADA). When required, a Super User key to access both

modes can be provided. The Super User key is also needed to access the
commissioning test mode. The password codes stored in the key can be
customized in each REF542plus for access restriction purposes.
*SLD view: this is the graphical part of the LCD. This part shows the single
line diagram of the switchgear. The status of the primary objects is
dynamically updated after every operation. If for example the circuit
breaker has been opened, its representation will reflect it.
3.2. Info and Menu area
The right side of the HMI LCD is for information and menu browsing. The
buttons to navigate through the menus and to change items are placed on this
area.

*Measurements: it displays the available measurements.
*Resets: to acknowledge alarms and other quantities.
*Events: to display protection starts and trips events.
*Protection: it displays the protection functions installed in the unit, and
allows displaying and changing their settings.
*Control: it displays the control functions list installed in the unit and
allows displaying and changing their settings.
*Service: relevant information on the HW and SW configurations and basic
setting of REF542plus.
*Tests: to access the test mode for the HMI and the primary objects.
Access to a few submenus is allowed only in some modes.
*LED bars: The three LED bars are available to show the most relevant
measurements acquired by REF542plus for a quick inspection of the
switchgear load situation. The three bars are marked M1, M2, and M3.
Each bar is composed of twelve LEDs, ten green and two red ones. The
ten green LEDs are normally dedicated to display between 0% and 100%
of the nominal value of the configured measurement. Each LED
corresponding then to 10% of the nominal value. The two red LEDs
indicate an overload condition of 20%. The measurements displayed by
the bars are set with the Operating Tool.
*Indication LEDs: 8 freely programmable, three-color LEDs are available
for indications. There are 4 pages of these LEDs. As a result, a total of 32
indication options can be programmed for events and status regarding
protection, control, monitoring, binary inputs and so on. The assignment
of the LED to a specific condition is done with the Operating Tool.
*Optical interface: This is the optical serial interface port to connect
REF542plus to a personal computer. By using the appropriate cable and
the Operating Tool, the following actions are possible:
*Download a configuration into the unit.
*Upload the current configuration from the unit.
*After a fault, upload the fault recorder data. This is possible only if the
fault recorder has been previously enabled with the Operating Tool.
Upload other information (measurements, binary inputs status, binary output
status).
Do not make any changes to the REF542plus configuration
unless you are familiar with REF542plus and the Operating
Tool. This might result in malfunction and loss of warranty.

1 Unit status
2 Network Communication status
3 Alarm
4 Interlocking Error
The HMI shows the following status information:
*Ready. This green LED is turned on when the unit is in the operational
state. The LED is switched off when the auxiliary power is not present or
when the unit is not operational (FUPLA is not running).
*Network Communication. This LED is meaningful only when the
REF542plus is equipped with a communication module. When a
communication module is detected the LED turns on to green. If the
module is not detected or fails, the LED turns red. When a Modbus
communication module is installed, the LED becomes orange if the
communication error rate increases. It becomes red when the
communication error rate prevents good communication. The LED
comes back to green when no communication errors occur or by
resetting the module status registers (see the Modbus technical reference).
When there is no communication module, the LED is always switched off.
*Alarm: this LED turns to red when the user defined alarms become
true. Several arbitrary alarm conditions can be defined and configured
with the Operating Tool. Alarm conditions could be the trip of a
protection function, loss of SF6 in the circuit breaker and so on. When
this LED is on, it is not possible to close the circuit breaker or to
download a new configuration. The alarm must be acknowledged first.
*Interlocking Error: this LED is usually green. It turns temporarily to
red when the user attempts an operation that would violate the
programmed interlocking conditions; for example switching a
disconnector with the circuit breaker in closed position.

5. Control modes
5.1. Available control modes
Local Control
It is possible to control the circuit breaker and other primary objects from the
HMI using the object control buttons. Open and close operations are possible
only if the interlocking logic programmed into the unit allow them. Remote
control from the SCADA is inhibited. Uploading and downloading the
configuration via the optical interface is possible.
Remote Control
The control of the circuit breaker and other primary objects from the HMI is
inhibited. The control is possible only remotely. Uploading and downloading
the configuration via the optical interface is possible.
No Control
It is not possible to control the circuit breaker and other primary objects both
from the HMI and remotely. Any kind of operation apart from the protection
trip is inhibited. Uploading and downloading the configuration via the optical
interface is possible.
Local and Remote Control
Both the local control and remote control from HMI are possible. Uploading
and downloading the configuration via the optical interface is possible.
The selection of this control mode requires caution, because
operations are allowed both from the HMI and remotely.
5.2. Changing the control modes
The next figure shows how to change the control mode. At first the menu E-
Key must be selected. Then the control key must be placed in the electronic
key sensor.
Select then the desired control mode by using UP and DOWN until it
is highlighted. Confirm the selection by pressing ENTER . After pressing
ENTER , the E-key status menu will appear again. Verify that the required
control mode has been properly set in the unit looking in the lower left corner
of the HMI. A text string there indicates the currently selected control and
protection mode.
