LED external control and internal control guardrail tube installation methods and common problems
Main materials: LED guardrail light; guardrail light installation clip, waterproof transformer, LED guardrail light main controller, LED guardrail light sub-controller, auxiliary materials: male and female plug, super five kinds of network cable, two core power cord, self-tapping screws, Colloidal particles, etc.
LED external control guardrail light installation steps:
The first step: first install the LED guardrail light on the wall: punch the wall, install the expansion screw, and then install the LED guardrail light, lock it with self-tapping screws; the distance between the guardrail lights is according to the customer’s requirements. Fixed; generally between 1CM and 3CM.
Step 2: Then connect the signal line and power line of the LED guardrail light. The signal line is generally a four-core or five-core male and female plug; the power cord is a two-core male and female plug;
The third step: install the power supply (transformer or switching power supply); calculate the number of guardrail lights that each transformer can carry according to the power of the transformer and the power of the guardrail lamp; for example, the 108-color LED colorful guardrail light is 10W/M; The LED guardrail light is 12W/M; if a 400W waterproof transformer is used, it can be equipped with 108 lamps and 36M tubes; for 144 lamps with 32 M tubes. If it can be changed, it can be equipped with a 36M tube; the transformer is placed between the 18th and the 19th, and the two lines are taken out, with 18 on each side.
Note: 1. The transformer generally only uses 80% to 90% of the power;
2. Regardless of the power of the transformer, the tube connected to each side should preferably not exceed 25M; because the power supply wire has power loss; the lower the brightness of the LED barrier light to the rear;
The fourth step: the installation of the LED guardrail light controller;
First install the sub-controller, directly connect the sub-controller to the LED guardrail lamp; there are generally three outlet ends at both ends of the sub-controller, one end of which is generally connected to the power supply line 24V or 12V, note that this power supply line is only the sub-controller For power supply, the power supply of the guardrail tube should be additionally connected. The other two terminals at the other end are the signal lines input from the main controller, and the other is the signal line for the output of the guardrail tube. Which control unit is marked on the sub-controller. Which one is connected to the control! Signal signal (five-core male and female plug), power supply to the power supply (two core male and female plug); then the sub-controller and the main controller signal docking, if the distance between the sub-control and the master will In the long-term, you can connect with super five types of network cables, so the signal is better; each sub-control can only bring a fixed number of LED digital tubes, which can generally be brought to 100M; when making the outline of the building, each sub-control belt has one way; The situation is installed according to the LED renderings (the manufacturer will help you calculate how much sub-control, how to use each sub-control, generally there will be installation drawings). The sub-control and the main control are also connected by a super five-wire network cable; the network cables are all eight lines, and the male and female signal plugs are connected with the network cable, and are now connected to the sub-control; the signal lines between the digital tubes of different loops are required. disconnect.
The fifth step: power, pass signal.
Connect all the transformers to a 220V main power supply, then use an air switch and time switch; control the LED digital tube (LED guardrail light) to be unified; then plug the main controller into the 220V power supply.
