Non-reversing Starter (Local I/O) – Two-wire Control
The E300 relay’s Operating Mode Non-Reversing Starter (Local I/O) – Two Wire
Control (Parameter 195 = 36) uses Input 0 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 0 is active.
The reset button of the E300 Operator Station is enabled for this operating
mode.
