Operating Modes
Introduction
The E300™ Electronic Overload Relay supports up to 54 Operating Modes,
which consist of configuration rules and logic to control typical full-voltage
motor starters, including:
•
Overload
•
Non-Reversing Starter
• Reversing Starter
• Wye/Delta (Star/Delta) Starter
•
Two Speed Starter
• Monitoring Device
This chapter explains the configuration rules, logic, and control wiring that is
required for the available Operating Modes (Parameter 195). Failure to follow
the configuration rules causes the E300 Electronic Overload Relay to go into
Invalid Configuration Mode and trip the E300 Electronic Overload Relay on a
configuration trip.
Overload (Network) The E300 Electronic Overload Relay’s default Operating Mode (Parameter 195)
is Overload (Network) in which the E300 Electronic Overload Relay operates as
a traditional overload relay with one output relay that is assigned as a normally
closed Trip Relay. You can use network commands to control the remaining
output relays that are assigned as Normal output relays.
Rules
1. For Control Module firmware v1.000 and v2.000, one output relay must
be assigned as a Trip Relay. Set any of the Output Ptxx Assignments
(Parameters 202…204) to Trip Relay.
2. For Control Module firmware v3.000 and higher, one output relay must be
assigned as a Trip Relay or Control Relay. Set any of the Output Ptxx
Assignments (Parameters 202…204) to Trip Relay or Control Relay.
3. Overload Trip must be enabled in TripEnableI (Parameter 183).
Wiring Diagram
The E300 Electronic Overload Relay is wired as a traditional overload relay with
one of the output relays configured as a normally closed Trip Relay.
