Text Notifications
The E300 Electronic Overload Relay EtherNet/IP Communication Module can
send a text message to a wireless phone by e-mailing the wireless phone's service
provider. The format for the text message is provided by the service provider and
looks similar to the example formats below.
• AT&T™: 10-digit wireless phone number@txt.att.net
• Sprint®: 10-digit wireless phone number@messaging.sprint.pcs.com
Limitations
Based on the functionality of the E300 Electronic Overload Relay EtherNet/IP
Communication Module, there are some limitations on when the e-mails can be
triggered.
• If two events occur at the same time, an e-mail is only sent for the most
significant error.
• If the device has been configured to send an e-mail for a lower prioritized
event and this event occurs at the same time as a higher prioritized event
for which the device has not been programmed to send an e-mail, an e-mail
is not sent for either event.
• The Clear e-mail is only sent when all events have been cleared and an
event e-mail has previously been sent.
Troubleshooting The following table identifies possible causes and corrective actions when
troubleshooting the E300 Electronic Overload Relay EtherNet/IP
Communication Module.

The E300 EtherNet/IP Communication Module is not
receiving power. Verify that the proper control voltage exists between
terminals A1 and A2 on the E300 Control Module.
Green, Red,
Not Illuminated
Flashing (once)
Normal This is a normal power-up sequence.
Green Flashing
The E300 EtherNet/IP Communication Module is online,
but with no connections established. Check the EtherNet/IP master and its scan list for correct
scanner configuration.
Green Solid
Normal operating state and the E300 EtherNet/IP
Communication Module is allocated to a master. No action is required.
Red Flashing One or more EtherNet/IP connections timed out. Reset the EtherNet/IP master device.
Red Solid
Diagnostics test failed on power-up/reset. An internal
fault exists. Cycle power to the unit. If the fault still exists, replace
the unit.
Duplicate EtherNet/IP module address exists. Two
modules cannot have the same address. Change the IP address to a valid setting and reset the
device.
A fatal communication error occurred. Check Ethernet media for proper installation.
