Introduction
A & A scales are electronic weighing scales that use load cells to measure the weight of the object being weighed. The load cells are connected to a junction box, which in turn is connected to a weight indicator. The weight indicator is the device that displays the weight of the object being weighed. The wiring diagram of A & A scales provides a detailed explanation of how the load cells, junction box, and weight indicator are connected.
The wiring diagram is essential for ensuring that the A & A scales are installed correctly and operate efficiently. It provides a visual representation of the wiring connections, which makes it easier for technicians to identify any faults and troubleshoot problems.
Components of A & A Scales
Before we delve into the wiring diagram of A & A scales, it is essential to understand the components that make up the scales. The following are the key components of A & A scales:
- Load Cells
- Junction Box
- Weight Indicator
- Power Supply
- Cables and Connectors
Load Cells
Load cells are the devices that convert the weight of the object being weighed into an electrical signal. They are typically made of metal and are designed to withstand the weight of the object being weighed. Load cells are connected to a junction box, which is responsible for amplifying and converting the electrical signal into a readable format for the weight indicator.
Junction Box
The junction box is responsible for connecting the load cells to the weight indicator. It amplifies and converts the electrical signal from the load cells into a readable format for the weight indicator. The junction box can be located near the load cells or the weight indicator, depending on the installation requirements.
Weight Indicator
The weight indicator is the device that displays the weight of the object being weighed. It receives the electrical signal from the junction box and converts it into a readable format for the user. Weight indicators can be digital or analog, depending on the application requirements.
Power Supply
The power supply is responsible for providing electricity to the load cells, junction box, and weight indicator. It can be an internal or external component, depending on the installation requirements.
Cables and Connectors
Cables and connectors are used to connect the load cells, junction box, weight indicator, and power supply. They are available in various lengths and types, depending on the application requirements.

|---|---|
| Red | Positive (+) |
| Black | Negative (-) |
| Green | Signal (+) |
| White | Signal (-) |
Connection of Junction Box to Weight Indicator
The junction box is connected to the weight indicator using shielded cables. The shielded cable reduces the electrical interference and noise that can affect the accuracy of the weight reading.
The wiring diagram of the junction box to the weight indicator is as follows:
| Junction Box Terminal | Weight Indicator Terminal |
|---|---|
| Positive (+) | Positive (+) |
| Negative (-) | Negative (-) |
| Signal (+) | Signal (+) |
| Signal (-) | Signal (-) |
Connection of Power Supply to Junction Box
The power supply is connected to the junction box using a two-core shielded cable. The wiring diagram of the power supply to the junction box is as follows:
| Power Supply Terminal | Junction Box Terminal |
|---|---|
| Positive (+) | Positive (+) |
| Negative (-) | Negative (-) |
Connection of Cables and Connectors
The cables and connectors are used to connect the load cells, junction box, weight indicator, and power supply. They are available in various lengths and types, depending on the application requirements. The wiring diagram of the cables and connectors is as follows:
