Troubleshooting
Introduction The purpose of this chapter is to assist in troubleshooting the E3 Overload Relay
using its advisory LEDs and diagnostic parameters.
Advisory LEDs The E3 Overload Relay provides the following advisory LED indicators:
Trip/Warn LED
The Trip/Warn LED will indicate device status by flashing a red trip code or an
amber warning code. The flash pattern followed by a pause identifies the specific
trip or warning. Refer to the product’s side label or the chart below for trip and
warning codes. Refer to the
Trip/Warn LED Troubleshooting Procedures section
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 as well as 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.
