Chapter 5 Operating Modes
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
assig
ned 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 relay is wired as a traditional overload relay with one of the output
relays configured as a normally closed trip relay. Figure 55
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 control relay, which receives commands from an
automation controller to energize the contactor coil.
Figure 55 - Trip Relay Wiring Diagram
For Control Module firmware v3.000 and higher, the E300 relay can also be
wired as a control relay so that the relay that is controlled by the communication
network opens when a trip event occurs. Figure 56
is a wiring diagram of a non-
reversing starter with Relay 0 configured as a control relay. Relay 0 receives
control commands from an automation controller to energize or de-energize the
contactor coil. Relay 0 also goes to an open state when there is a trip event.
