The 15 programmable three-color LEDs are used for alarm indication. An individual
alarm/status signal, connected to any of the LED function blocks, can be assigned to
one of the three LED colors when configuring the IED.

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.
Generator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062
Normal operation.
A protection function has tripped. An indication message is displayed if the
auto-indication feature is enabled in the local HMI.
The trip indication is latching and must be reset via communication, LHMI or
binary input on the LEDGEN component. To open the reset menu on the
LHMI, press .
