The SDK-6 computerized (latitude and longitude) intelligent street light controller uses a dedicated computer chip to automatically determine the on/off time according to the local latitude and longitude and seasonal changes. Users do not need to input specific switch times (the local latitude and longitude are pre-set at the factory). The controller can be put into normal use.
The controller has two outputs, A, B, and each can be set to three modes: "all night light" (turn on in the evening until early morning), "midnight light" (turn on in the evening until late at night), and "2 on 2 off" (turn on the midnight light again in the early morning). At the factory, route A is set to full night light and route B is set to midnight light mode.

To save power consumption, the controller operates normally with a flashing second signal. In addition to the control status indication of channels A and B. Do not display any other content. Press any button or when the power is just turned on, the current clock will be displayed and will turn off after 1 minute.
2. Query switch time
The query button allows you to view the actual on/off time for the current day and any other day. Press the 'Query' button to immediately start sequentially querying the switch time. Each time you press the 'Query' button, the display content changes, and the display order is as follows:

Changes to the date during the query process do not affect the actual running calendar clock within the controller; The query process will not interfere with the output control status of channels A and B. After the query is completed, press and hold the "Query" button for more than 2 seconds, or stop pressing the button for 1 minute. Restore the display clock.
3. Adjustment of control parameters (setting method)
By setting, the clock of the controller can be adjusted. Change the originally set latitude and longitude, and modify the control mode of A and B routes: the switch time determined by latitude and longitude can be adjusted within ± 120 minutes.
In the clock display state, press the "Settings" button for more than 2 seconds to enter the settings state; After entering the setting state, the output control remains unchanged from the original state.
There must be a current modification item flashing in the setting state. The contents that can be set are: hour, minute, second, year, month, day, longitude (east longitude), latitude (east longitude), latitude (north latitude), evening light on time, morning light off time, A route working mode (A=1, 2, 3 respectively represent all night, midnight, 2 on 2 off), B route working mode, half night light off time (used in conjunction with midnight light and 2 on 1 mode).
Use the "+" and "-" keys to adjust the current flashing content, press the "Search/Move" key to move the current flashing content, and press the "Set/Line Break" key to change pages; After modification, hold down the "Settings/Line Break" button for more than 2 seconds. Or stop pressing the button for 3 minutes, save the edited and modified content, exit the settings state, and restore the display clock.

4. Manual emergency light on
Press the 'Manual' button for more than 2 seconds. A. The B output immediately turns on the light, and the panel indicates "manual"; Press again to restore to automatic mode.
5. Light sensing control with light control controller
Type 6 controller is the basic type; The light control controller has added light sensing input. Based on the determination of the switch time according to latitude and longitude, fuzzy mathematical methods are used to process the changes in natural light. The lights are turned on appropriately in the evening on rainy days, with a maximum advance time of 30 minutes. Once the light is turned on, it will not switch frequently due to fluctuations in lighting.
The benchmark value for comparison adopts a self-tuning intelligent fine-tuning method, which does not require manual adjustment; The automatic calibration technology used can eliminate the detection error of actual illumination caused by different installation conditions of the photosensitive device and the drift of device parameters during long-term operation. The requirements for installing a light control controller are: it should be able to feel natural light and not be disturbed by other artificial lighting except for the street lamps it controls.
