Chapter 5 Operating Modes
Reversing Starter (Local I/O) – Two-wire Control with Feedback
The E300 relay’s Operating Mode Reversing Starter (Local I/O) – Two Wire
Control (Parameter 195 = 41) uses Input 0 to control Output Relay 0, which
controls the contactor coil of the forward contactor, and Input 1 to control
Output Relay 1, which controls the contactor coil of the reversing contactor.
Both Input 0 and Input 1 are maintained signals, so the reversing starter remains
energized when either Input 0 or Input 1 is active. Both Input 0 and Input 1 must
be in a de-active state before changing to another direction.
The auxiliary contact from the starter’s forward contactor is wired into Input 0,
and the auxiliary contact from the starter’s reversing 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
Time
out Warning in WarningEnableC (Parameter 192) must be enabled.
6. Communication Fault & Idle Override (Parameter 346) must be enabled.
7. Network Fault Override (Parameter 347) must be enabled.
Wiring Diagram
The E300 relay’s Output Relay 0 is wired as a control relay to the forward
contactor and Output Relay 1 is wired as a control relay to the reversing
contactor. Both relays open when a trip event occurs. Figure 136
is a wiring
diagram of a reversing 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 Reversing Starter (Local I/O) – Two-wire Control operating mode uses the
signal from Input 0 or Input 1 to control the starter. When an E300 powers up,
the starter energizes if either Input 0 or Input 1 is active.
