Operating Modes Chapter 5
Two-speed Starter (Local I/O) – Three-wire Control
The E300 relay’s Operating Mode Two Speed Starter (Local I/O) – Three Wire
Control (Parameter 195 = 48) uses a normally open momentary push button in
Input 0 to energize Output Relay 0, which controls the high-speed contactor coil.
A normally open momentary push button in Input 1 is used to energize Output
Relay 1, which controls the low-speed contactor coil. A normally closed push
button in Input 2 is used to de-energize Output Relay 0 and Output Relay 1.
Both Input 0, Input 1, and Input 2 are momentary signals, so the two-speed
starter only energizes if Input 2 is active and Input 0 or Input 1 is momentarily
active.
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.
