Zhejiang University Zhongkong DCS issues
Thread Content
Our company uses two Zhejiang University Zhongkong DCS systems, with two control cabinets. Due to internal company reasons, we now want to move these two control cabinets to a new location (600 meters away). What issues should we be aware of? It also has a UPS power supply. I’m not quite sure how to deal with issues related to wiring, lighting, and the power supply; any experts out there who can offer some advice would be greatly appreciated. It’s urgent
1. Don’t rush; believe that problems can always be solved. 2. Actually, if you think about it carefully, it’s not much different from when the new DCS system was introduced. 3. First, please describe the situation on site in more detail. Currently, each of the two control cabinets is equipped with a controller, which means there are two separate systems ； It’s still one system; the other cabinet is a remote cabinet ； Secondly, regarding what you said about \"wanting to move these two control cabinets to another location (a distance of 600 meters)\\", does that mean both cabinets need to be moved 600 meters to another place at the same time, or is it one cabinet that needs to be moved closer to the other?
Originally, there were two control cabinets together, forming one system; now they have been moved to another location. What concerns me most is how to handle the power supply inside, the signal cables, and other similar issues. Please advise, those with experience

First, communicate well with the technical team and shut down the control system. Find an electrician to shut down the UPS, and disconnect the cables linking the two cabinets. Be careful not to lose the labels on those cables; it’s best to gather the cables from each cabinet together and tie a knot at the end, so it will be easier to reconnect them later. As for the controllers and cards inside the control cabinet, there is no need to remove them; simply lock the cabinet door and be careful during transportation. As for the power supply and UPS components, it is best to seek the assistance of professional electrical technicians. Here’s another suggestion: use a digital camera to take good photos of the control cabinet before it is disassembled, especially of the parts that will be taken apart, such as the wiring terminals and power terminals. Take photos while removing it, and mark the terminals of the wires that have been removed. Be careful and there will be no problem.
The original poster might have merged two control rooms into one; now they want to move the two control cabinets from one control room to another. It seems like it will require the same amount of work as starting over from scratch, or even more. Pay attention to the following points: 1. If there are diagrams for the original system, organize the most recent modifications accordingly. There are no images, so you’ll need to create one yourself; otherwise it will be impossible to start with the wiring. 2. Power supply: if it is to be shared with the new system, check whether its capacity is sufficient; it’s not difficult to set it up separately either – just follow the instructions in the diagram. 3. Make marks when removing the stitches; it’s best to secure them with tape, as labels can sometimes get removed when the threads are pulled. 4. Pay attention to grounding; it cannot be taken lightly – follow the specifications. 5. If it is not moved, it can be used as a remote station, allowing this system to be controlled from the new control room.
