Reversing Starter (Local I/O) – Three-wire Control
Operating Mode Reversing Starter (Local I/O) – Three Wire Control (Parameter 195 =
42) uses a normally open momentary push button in Input 0 to energize Output Relay
0, which controls the forward contactor coil. A normally open momentary push
button in Input 1 energizes Output Relay 1, which controls the reversing contactor
coil. A normally closed push button in Input 2 de-energizes Output Relay 0 and
Output Relay 1. Both Input 0, Input 1, and Input 2 are momentary signals, so the
reversing starter only energizes if Input 2 is active and Input 0 or Input 1 is
momentarily active.
Input 2 must be momentarily de-active before changing to another direction.
InterlockDelay (Parameter 215) defines the minimum time delay when switching
direction.
The reset button of the E200 Operator Station is enabled for this operating mode.
Rules
1. Four digital inputs must be available on the Control Module
2. Output Pt00 Assignment (Parameter 202) must be set to Control Relay.
3. Output Pt01 Assignment (Parameter 203) must be set to Control Relay.
4. Overload Trip must be enabled in TripEnableI (Parameter 183).
5. Communication Fault & Idle Override (Parameter 346) must be enabled.
6. Network Fault Override (Parameter 347) must be enabled.
