When we use the weighing junction box for the correct operation methods are required to master, so that in the use of the process can avoid errors. The following small braid for you to explain the weighing sensor and junction box connection of the correct method.
Connection between weighing sensor and junction box
The cable of the weighing sensor passes through the weighing platform and enters the junction box through the sealed joint. According to the different colors of the four-core or six-core cable, or after measurement, the positive and negative feedback, the positive and negative excitation power supply and the positive and negative signals are connected to the corresponding terminals in the junction box. Bind the remaining cable of the sensor with plastic tape.
Connection box is connected with weighing display instrument.
One end of the special shielded cable enters the junction box through a sealed joint, and each core wire is connected to the corresponding junction post in the junction box. The other end is welded through a metal pipe to the special plug corresponding to the weighing display instrument for insertion into the socket of the weighing display instrument.
There are three points to note:
1. Different weighing display instruments need different weighing display sockets, different plug forms and different connections.
2. After the input and output wires in the junction box are connected, the junction should be tightened, tightened and sealed, put in desiccant, do a good job of moisture-proof, and then fix the junction box plate.
3. For different weighing sensors, input, output and feedback should be distinguished according to different color labels.
System grounding
The grounding of electronic weighing system is very important. It not only protects personal safety, but also ensures the stability and reliability of the system. The grounding measures of the system can not be ignored. Generally, the electronic weighing system has two grounding points, one is the weighing platform grounding, with one or more grounding cables, the weighing body and grounding pile connected. The other is the grounding pile in the pound room, so that the instrument case is grounded.
