A wiring diagram for a mobile crushing plant, such as the B 150 model operating at 400V, is a detailed schematic that outlines the electrical connections and components within the system. This diagram is crucial for installation, maintenance, and troubleshooting purposes. Below is a general guide on what to expect in such a wiring diagram:
Key Components in the Wiring Diagram:
1. Power Supply (400V)
– Input terminals for the 400V AC power supply.
– Main circuit breaker or disconnect switch.
2. Control Panel
– PLC (Programmable Logic Controller) or control unit.
– Relays and contactors for motor control.
– Emergency stop buttons and safety switches.
– Indicators and alarms (e.g., power on, fault).
3. Motors
– Crusher motor.
– Conveyor motor(s).
– Vibrating feeder motor.
– Cooling fan motor (if applicable).
4. Sensors and Feedback Devices
– Limit switches for conveyor positioning.
– Temperature sensors for motors and bearings.
– Vibration sensors.
5. Power Distribution
– Distribution boards or terminal blocks.
– Fuses or circuit breakers for individual components.
6. Communication Interfaces
– Ethernet or RS485 connections for remote monitoring.
– HMI (Human-Machine Interface) connections.
General Wiring Diagram Structure:
1. Main Power Circuit
– Shows the connection from the 400V supply to the main breaker and distribution board.
2. Motor Control Circuits
– Includes wiring for each motor, showing connections to contactors, overload relays, and control switches.
3. Control Circuit
– Details the wiring for the PLC, relays, and other control devices.
4. Safety Circuits
– Includes emergency stop circuits, safety interlocks, and fault detection systems.
5. Sensor and Feedback Circuits
– Shows wiring for sensors and feedback devices connected to the control system.
