DCS Installation and Commissioning Considerations

General installation of DCS control systems is strictly regulated. It is particularly important to select construction units with good qualifications and construction experience. After the selection of the control system, the technical personnel of the construction unit shall be involved in the design of the control system, the construction drawings, the formulation of construction measures and technical training. Before the project is started, a strict schedule must be established according to the schedule requirements, and the construction unit must be required to organize the construction strength and come up with their construction plans. Therefore, pay special attention to the following issues during DCS installation and commissioning:

1. During construction, it is necessary to pay attention to the reliable insulation of the cabinet and the ground and the grounding of the busbars of the cabinet. At the same time, the holes must be fireproofed, and the cabinets must be protected against vibration.

2. When laying cables, special attention should be paid to the separation of strong electricity and weak electricity, and reliable grounding and anti-jamming of shielded cables. In the wiring process must be in accordance with the design drawing _ [, in the wiring, cable and core markings to be clear and complete, can be maintained for a long time; crimp terminals must be pre-installed with insulation tube end processing.

3, to strictly control the environmental conditions of electronic equipment, pay attention to do a good job of fire, air conditioning, ventilation and lighting work. Special mention should be made of ventilation and air conditioning. Since the DCS control system has strict temperature requirements, the air conditioning system should be put into operation as soon as possible. The air outlet of the air conditioner must not be facing the cabinet or other DCS electronic equipment, so as to avoid the condensation water from penetrating into the equipment. At the same time, electronic cards must not allow dust to enter. Therefore, it is required that the electronic environment can always keep the environment clean and the filter screen clean, and pay attention to dehumidification and adjustment of the temperature.

The DCS installation and commissioning can be imagined to the importance of production and ensure the smooth production. However, if you do not pay attention to the precautions of DCS installation and commissioning during the production process, it will easily cause errors in production and affect the production results.
