LED Status Indication
The following LED status indicators are provided on the E3 Overload Relay. See
Chapter 12 for detailed information on each status.
Network Status —
Illuminated in green or red, this indicates the network
connection status.
Trip/Warning —
Under a warning condition, the LED status flashes a sequence
of red and/or amber. Under the trip condition, the LED status flashes a sequence
of red. In either condition, the flash pattern followed by a pause identifies the
specific trip or warning. The meaning of the flash pattern can be found on the E3
Overload Relay’s side label or Table XX on page XX.

LED illuminates amber.
IN 1…IN 4 —
When the user-connected device contact is closed, the LED status

Test —
If Test Enable is activated, the trip relay contact will open if the E3
Overload Relay is in an untripped condition and the Test/Reset button is

ATTENTION: The E3 Overload Relay’s output control firmware latches
OUT A and OUT B closed upon receipt of a network close command. The
outputs will maintain the commanded closed state until receipt of a
network open command. Parameters OutX Pr FltState and OutX Pr
FltValue, found in the E3 Overload Relay’s output setup group, allows
flexibility concerning the operation of the outputs in the event of a trip.
Factory default settings cause the outputs to open upon
occurrence of a trip. E3 outputs that were closed prior to a trip
will reclose upon trip reset, provided that a network open
command is not received first.
NOTE:
IN 3, IN 4, and OUT B are available only on the E3 Plus Overload Relay.
