Troubleshooting
Introduction
This chapter helps troubleshoot the E300 Electronic Overload Relay using its
advisory LEDs and diagnostic parameters.
Advisory LEDs
All E300 Electronic Overload Relay Communication Modules and Operator
Station have two diagnostic status indicators: Power LED and Trip/Warn LED.
You can use these diagnostic status indicators to help identify the state of the
E300 Electronic Overload Relay and the reason for the trip or warning event.
Power LED
The E300 Electronic Overload Relay Power LED identifies the state of the E300
Electronic Overload Relay system.

ATTENTION:
Servicing energized industrial control equipment can be
hazardous. Electrical shock, burns, or unintentional actuation of controlled
industrial equipment may cause death or serious injury. For safety of
maintenance personnel and others who may be exposed to electrical hazards
associated with the maintenance activities, follow the local safety-related work
practices (for example, the NFPA 70E, Part II, Electrical Safety for Employee
Workplaces, in the United States) when working on or near energized
equipment. Maintenance personnel must be trained in the safety practices,
procedures, and requirements that pertain to their respective job assignments.
Do not work alone on energized equipment.
ATTENTION:
Do not attempt to defeat or override fault circuits. The cause of a
fault indication must be determined and corrected before attempting
operation. Failure to correct a control system or mechanical malfunction may
result in personal injury and/or equipment damage due to uncontrolled
machine system operation.
