Description: 1. This controller is a two-axis solar tracking controller: precise internal and external ring hole sensors are used to detect the position of the sun, and the sensor signal is analyzed and evaluated by the single-chip circuit of the controller. 2. The platform corresponding to this controller must be a platform with two degrees of freedom, and the platform drive motor is a DC brush motor: the motor voltage is 12 or 24 V, and the current of a single motor must be less than 15 A (by default, each axle is equipped with a 10A fuse). We all four directions of the platform should be limit switches. The controller consists of the following main components: Main Controller Insolation Sensor: 1. 4 mm main controller mounting hole: left and right hole distance: 174 mm, top and bottom hole distance: 60 mm 2. The product adopts waterproof housing as housing and is rainproof when installed vertically: there are up to 6 waterproof sockets to connect the line. 3. All circuit connections on the motherboard accept terminal wiring, and the top cover ma display and six operating buttons that can be used to display parameters and perform manual operations or parameter settings. Sunlight Sensor: 1. Install the sunlight sensor on the upper level of the platform and observe the operation of the platform. Make sure you are parallel to the top plane of the platform. When the platform is erected, the direction of the outlet hole on the detection head should be pod ground. 2. In the northern hemisphere, the detection head should be mounted on the eastern edge of the northern side of the platform, if possible. For installations in the southern hemisphere, this is the eastern edge of the southern wall Main Distribution Box: The main control box should be installed close to the platform base column, without moving with the platform, as far as possible, so that it is not exposed to rain, sunlight and other factors, and the outlet hole should be directed downwards to prevent rainwater from entering. It is better to be able to observe and operate comfortably. Installation method: Sunlight Sensor: 1. Install the sunlight sensor on the upper level of the platform and observe the operation of the platform. Make sure you are parallel to the top plane of the platform. When the platform is erected, the direction of the outlet hole on the detection head should be pod ground. 2. In the northern hemisphere, the detection head should be mounted on the eastern edge of the northern side of the platform, if possible.

It is better to be able to observe and operate comfortably. Limit switch wiring: 1. Limit switch is necessary There are two ways to limit the limit from AB (the limit switch must be purchased by yourself). A: A: Use the external limit switch control method to realize the limit: The external limitation method is: Use the normally closed micro switch to set the four platform positions that need to be limited, and control directly the corresponding motor. power circuit to reach the limit, With this method, care should be taken to ensure that the limit switch and the diode connected in parallel can conduct sufficient current. If you are using a limit electric pusher, you do not need this method because the limit electric pusher is equipped with an A-mode limit circuit. B: The limit signal is entered into the controller to meet the limit and a limit switch with a normally open contact must be used. When a given direction reaches the limit, the switch is pushed upwards, the switch is closed and turned on, and the limit is turned on. The Masa (G) of the clamp is compact to the clamp in the right direction, and the output in that direction is stopped at that time. With this method, care should be taken to ensure that the limit switch and the diode connected in parallel can conduct sufficient current. If you are using a limit electric pusher, you do not need this method because the limit electric pusher is equipped with an A-mode limit circuit. ) Note that the top is the detection area. When the metal is within a 5 mm radius, a limit signal will be displayed. The two-axis drive motor should be able to drive the platform to move smoothly within the appropriate range when not connected to the control board and powered from a separate power source. In this case, the motor can be connected to the appropriate contact of the motor terminal on the control board. , Please note that the east-west axle motor and north-south oil engine should not be incorrectly connected. 1 * Solar Tracking Controller Kit
