Commands
Introduction The purpose of this chapter is to provide detailed information regarding the
resetting, clearing, and pre-configuration functions of the E300 Electronic
Overload Relay. The E300 Electronic Overload Relay provides three types of
commands:
• Trip Reset
• Configuration Preset
• Clear Command
Trip Reset Trip Reset (Parameter 163) allows the user to reset an E300 Electronic Overload
Relay when it is in a tripped state. Trip Reset has the same functionality as
pressing the blue reset button on E300
communication module and using the
Trip Reset bit in the consumed output assemblies of a communications network.
A trip reset can only be performed when all conditions for the trip event have
been cleared. For an overload trip event, the % Thermal Capacity Utilized
(Parameter 1) must be below the value specified in Overload Reset Level
(Parameter 174).
