Introduction
This chapter provides detailed information aboutthe 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 you 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 that is specified in Overload Reset Level
(Parameter 174).
Table 352 - Trip Reset (Parameter 163)
Configuration Preset
The E300
Electronic Overload Relay has a number of preset configurations that
allow you to quickly configure all of the configuration parameters that are needed
for a specific operating mode in one command. This also allows you to restore the
factory default values for all configuration parameters in the E300
Electronic
Overload Relay.
