Troubleshooting
Introduction The purpose of this chapter is to assist in troubleshooting the EC4 Current
Monitoring Relay using its advisory LEDs and diagnostic parameters.
Advisory LEDs The EC4 Current Monitoring Relay provides the following advisory LED
indicators:
Trip/Warn LED
This Trip/Warn LED will indicate device status by flashing a red trip code or an
amber warning code. The number of flashes 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
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.
