Non-reversing Starter (Local I/O) – Two-wire Control with Feedback
The E300 relay’s Operating Mode Non-Reversing Starter (Local I/O) – Two Wire
Control with Feedback (Parameter 195 = 37) uses the state of Input 1 to control
Output Relay 0, which controls the contactor coil. Input 0 is a maintained value,
so the non-reversing starter remains energized when Input 1 is active.
The auxiliary contact from the non-reversing starter’s contactor is wired into
Input 0. 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.
The reset button of the E300 Operator Station is enabled for this operating
mode.

4. Feedback Timeout Trip in TripEnableC (Parameter 186) or Feedback
Time
out Warning in WarningEnableC (Parameter 192) must be enabled.
