Reversing Starter (Local I/O) – Two-wire Control
The E300 relay’s Operating Mode Reversing Starter (Local I/O) – Two Wire
Control (Parameter 195 = 40) 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
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.
