The relay does not operate, a limit violation is displayed only by the
LEDs
• Relay enable on:
The relay operates with a limit violation
♦ The red LED signals an existing announcement status, which as a rule
is linked to an existing Alert or Danger alarm.

<Trip override> active, or <Relay latching> active.
Note:
The status of the logical connection between the conditions of
TRIPOVERRIDE and ACKNOWLEDGE can be queried as a parameter in
