Trip/Warn
The E300 relay Power LED identifies the reason for the trip or warning event. The
E300 relay displays a long and short blinking pattern to identify the reason for the trip
or warning event.

Verify that the proper control voltage exists between
terminals A1 and A2 on the E300 Control Module.
This is a normal power-up sequence.
Check the EtherNet/IP master and its scan list for correct
scanner configuration.
No action is required.
Reset the EtherNet/IP master device.
Cycle power to the unit. If the fault still exists, replace
the unit.
Change the IP address to a valid setting and reset the
device.
Check Ethernet media for proper installation.
Check the Ethernet cabling to make sure it is properly
installed.
No action is required.
No action is required.
Check the DeviceNet control power on the A1 and A2
terminals of the E300 Control Module.
This is a normal power-up sequence.
The E300 Module may require commissioning due to
configuration missing, incomplete, or incorrect.
The E300 DeviceNet Communication Module is
allocated to a master.
Verify configuration and/or reset DeviceNet master.
Verify configuration and/or reset DeviceNet master.
Cycle power to the E300 Module. If the fault still exists,
identify/replace the faulty component(s). Change the
node address to a valid setting and reset the E300
Module. Verify integrity of the DeviceNet network and
corresponding cabling to ensure proper installation.
