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.

Front communication

The RJ-45 port in the LHMI enables front communication.
• The green uplink LED on the left is lit when the cable is successfully connected to the port.
• The yellow LED is not used; it is always off.
