Non-reversing Starter (Local I/O) – Three-wire Control
The E300 relay’s Operating Mode Non-Reversing Starter (Local I/O) – Three
Wire Control (Parameter 195 = 38) uses an active state in Input 1 (normally open
momentary push button) to energize Output Relay 0, which controls the
contactor coil, and a de-active state in Input 0 is used (normally closed push
button) to de-energize Output Relay 0. Both Input 0 and Input 1 are momentary
values, so the non-reversing starter only energizes if Input 0 is active and Input 1 is
momentarily active.
The reset button of the E300 Operator Station is enabled for this operating
mode.
