There is a textual part of the LCD, which shows the menu, the measurement values,
the events and any information accessible through the menu structure.
SLD view
The SLD view 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: for example, if the circuit breaker has been opened, the SLD
view will reflect it.
Open CB for Fast Opening
When pressed simultaneously with the normal open button, the Open CB button
allows the fast opening of the circuit breaker independently from the selected
control mode. This feature must be enabled in the unit with the Operating Tool.
Moreover, it is also possible to have several, completely user defined command
buttons on the HMI. These virtual push buttons are available from the dedicated
HMI menu. During REF 542plus configuration, the user defines what command
buttons are required. Typical examples might be: start of a transfer switch or of any
other automation sequence, fault recorder activation, start of a load shedding
sequence and so on.
Due to the user defined command buttons, REF 542plus automation capabilities can
cope with any requirements.
