Operating Modes Chapter 5
Two-speed Starter (Network) with Feedback
The E300 relay’s Operating Mode Two-speed Starter (Network) with Feedback
(Parameter 195 = 10) uses network tags LogicDefinedPt00Data in Output
Assembly 144 to control Relay 0, which controls the high-speed contactor coil
and LogicDefinedPt01Data in Output Assembly 144 to control Relay 1, which
controls the low-speed contactor coil. Both LogicDefinedPt00Data and
LogicDefinedPt01Data are maintained values, so the two-speed starter remains
energized when LogicDefinedPt00Data or LogicDefinedPt01Data has a value of
1. You can program the appropriate state of the starter when communication is
lost using the Network Communication Fault and Network Communication
Idle parameters (Parameters 569 – 573) described in Chapter 4
.
The auxiliary contact from the high-speed contactor is wired into Input 0, and
the auxiliary contact from the low-speed contactor is wired into Input 1. If a
feedback signal is not received before the time identified in Feedback Timeout
(Parameter 213), then the E300 issues a trip or warning event.
InterlockDelay (Parameter 215) defines the minimum time delay when switching
direction.
The reset button of the E300 Operator Station is enabled for this operating
mode.
Rules
1. Available for Control Module firmware v5.000 and higher.
2. Output Pt00 Assignment (Parameters 202) must be set to Control Relay.
3. Output Pt01 Assignment (Parameters 203) must be set to Control Relay.
4. Overload Trip must be enabled in TripEnableI (Parameter 183).
5. Feedback Timeout Trip in TripEnableC (Parameter 186) or Feedback
T
i
me
out Warning in WarningEnableC (Parameter 192) must be enabled.
Wiring Diagram
The E300 relay’s Output Relay 0 is wired as a control relay to the high-speed
contactor and Output Relay 1 is wired as a control relay to the low-speed
contactor. In this configuration, both relays are controlled by the communication
network and open when a trip event occurs. Figure 165
is a wiring diagram of a
Two-speed Starter with Output Relay 0 and Output Relay 1 configured as
control relays and the contactor auxiliary contacts wired to Input 0 and Input 1.
The Two-speed Starter (Network) operating mode uses the value in network
tag LogicDefinedPt00Data or LogicDefinedPt01Data to control the starter. When
communication is restored between an automation controller and the E300,
the starter energizes if the value in LogicDefinedPt00Data or
LogicDefinedPt01Data is set to 1.
