Chapter 5 Operating Modes
as a normally closed trip relay or a normally open control relay. The Overload
(Operator Station) operating mode is used when an automation controller uses
the start and stop keys of the E300 Operator Station for its motor control logic.
You can use network commands to control the control relay or any of the
remaining output relays that are assigned as normal output relays.
The reset button of the E300 Operator Station is enabled, and the Local/
Remote yellow LED is illuminated to indicate that the operator station is being
used for local control.
Rules
1. Available for Control Module firmware v5.000 and higher.
2. One output relay must be assigned as a trip relay or control relay. Set any of

Control Relay.
3. Overload Trip must be enabled in TripEnableI (Parameter 183).
4. Operator Station Trip must be disabled in TripEnableC (Parameter 186).
5. Operator Station Option Match Trip or Warning must be enabled.
• Option Match Trip or must be enabled in TripEnableC
(Parameter 186)
• O
perator Station must be enabled in Mismatch Action
(Parameter 233)
• An
operator station must be selected in Operator Station Type

Wiring Diagram
The E300 relay is wired as a traditional overload relay with one of the output
relays configured as a normally closed trip relay. Figure 59
is a wiring diagram of a
non-reversing starter. Relay 0 is configured as a trip relay, and Relay 1 is
configured as a normally open Normal Relay, which receives commands from an
automation controller to energize the contactor coil.
