Relay messages
Default message Figure 3-5: Relay default messages
Target messages Target messages are automatically displayed for any active condition on the relay such as
pickups, trips, or alarms.
The relay displays the most recent event first, and after 5 seconds will start rolling up the
other target messages until the conditions clear and/or the RESET command is initiated.
The Target Messages can be reviewed by pressing either the MESSAGE UP or MESSAGE
DOWN key. If a RESET command is not performed but any of the other faceplate
pushbuttons is pressed, the display will not show the target messages unless the user
navigates to
ACTUAL VALUES > A4 TARGET MESSAGES, where they can be reviewed. If the
target messages have not been cleared before the user presses a pushbutton different
from “RESET”, they will reappear on the screen after the time specified under the
SETPOINTS > S1 RELAY SETUP > FRONT PANEL > MESSAGE TIMEOUT setting, that will start
timing out from the last pressed pushbutton. The following shows the format of a typical
Target Message:
