Parameter management

The LHMI is used to access the relay parameters. Three types of parameters can be read
and written.
• Numerical values
• String values
• Enumerated values
Numerical values are presented either in integer or in decimal format with minimum and
maximum values. Character strings can be edited character by character. Enumerated
values have a predefined set of selectable values.
Changing the function block on or off affects the visibility of its
parameters in the menu.
Changing the value of certain relay parameters affects the visibility or
range of other parameters in the menu. This indicates which parameters or
parameter values become obsolete due to the change. The relay changes
the visibility or range of these parameters immediately even before the
changed values have been committed.
Some parameters may be hidden because the function is off or the setting
visibility is set to "basic" instead of "advanced".

Front communication

The RJ-45 port in the LHMI enables front communication. Two LEDs are located above
the communication port.
• The green uplink LED on the left is lit when the cable is successfully connected to the
port.
• The yellow communication LED on the right flashes when the protection relay
communicates with the connected device.
