Operation
Electrical power from the utility grid enters the main circuit breaker/disconnect on the electrical
enclosure door as 3-phase alternating current. The power is then distributed in two directions.
The 3-phase AC, at the voltage provided from the grid, is routed to the motor starter contactors
and then to the main motor. Single phase AC is routed to the transformer.
Figure 8-1: Electrical Control Power
The multi-tap transformer converts the incoming voltage to 230 volt AC that is routed to both the
motor starter contactors and to the power supply. The power supply then provides 24 volt direct
current to the control circuits, including the emergency stop logic, the programmable logic
controller (PLC), optical relays, display screen and optional control functions.
When the
START
button is pressed on the control panel, the motor control relay closes and 230
volt AC power is sent to the contactor coils. The coils close, sending the incoming power to the
motor. When the
STOP
button is pressed, the motor control relay opens, disconnecting power to
the contactor coils, stopping the motor.
The motor starter contactors are solenoid operated by 230 volt AC control power. The contactors
are arranged in a wye-delta starter circuit. Wye-delta starter circuits consist of three, 3-phase
contactors used to start the motor slowly, minimizing the initial current draw.
