Ⅱ. Installation and wiring
- Installation of controller should be stable and dimensions are as follows:
Overall dimension:82×58×20(mm)
Installation dimension:43×75(mm)
Installation hole diameter:3.5(mm)
- controller can work under 12V or 24V voltage. Please connect storage battery at first for use. Controller will automatically identify voltage of storage battery and start to work. If it is the 12V system, the nixie tube will show ‘0’. If it is the 24V system, the nixie tube will show ‘1’.
- Please connect the storage battery first, then the photoelectric cell and the load.Pay attention to the “+” and “–” in case of reverse connection.
- The anti-reverse connection is available. Even you connect the photocell and battery wrongly, the controller will not be harmed.
Wiring diagram is as follows:
Ⅲ.Connection of LED
- The Controller is internally installed with constant current source. The max. output voltage is 70V. The max. amount of LED lights can be connected is 20.
- The controller can automatically identify voltage of 12V and 24V. While connect with LED load, please ensure the number of LED lights in series is appropriate.
The following data is we recommended.
System voltage | The Min.No.(n) Of LED lights In series |
Output voltage |
Output power |
12V | n≥ 5 | VO≥ 16V | PLED≤ 30W |
24V | n≥ 10 | VO≥ 32V | PLED≤ 70W |
- Please connect LED light first and then open the load.
Warning: if the number of LED in series is not appropriate, the controller or the LED load will be harmed.

Ⅴ.Introduction of mode and table of settings
controller has two working modes. Table of settings is as follows:
- Light control + time control (1.-4.): When there is no sunlight, the light intensity will fall to the starting point. The controller will affirm the starting signal after a delay of 10 minutes. Load will be opened as per set parameters to start working and will switch the power as per the set time. When there is sunlight, the light intensity will rise up to the starting point. The controller will close output after confirming closing signal in a delay of 10 minutes and the load will stop working.
- Demo mode (5.): Under this mode the user can control the on and off of load by keys no matter it is day or night. The time for demo mode is 8 seconds. Without key press after 8 seconds, it will back to the normal working mode.
LED1 Display | Mode | LED 2 Display | parameter |
1. | Working with 100% power | 0 – 4. | Working for 0-14 hours with 100% power |
2. | Working with 75% power | 0 – 4. | Working for 0-14 hours with 75% power |
3. | Working with 50% power | 0 – 4. | Working for 0-14 hours with 50% power |
4. | Working with 25% power | 0 – 4. | Working for 0-14 hours with 25% power |
5. | Demo mode | 0 – 4 | 0 load is off 1 load works with 100% power 2 load works with 75% power 3 load works with 50% power 4 load works with 25% power |
Ⅵ.Methods for setting
1. Modes and parameter scan
There are two nixie tubes installed on the controller. The first one shows the modes and the second shows the parameter under the mode. In normal state, the mode and parameter will show from nixie tubes after the key-press. Every key-press shows different number (mode) in first nixie tube and the the parameter changes accordingly in the second one.
2. Adjustment of parameter.
Press a key for more than 3s till the nixie tube shows the parameter starting to twinkle. Release the key and then press the key again, figures of nixie tube will change one digit each time until digits shown on the nixie tube match the digits corresponding to the mode the user has selected. Wait until the nixie tube stop twinkling or press the key again for more than 3s to finish the setting process.
- Demo mode.
After finishing the “mode and parameter scan” process, adjust the fist nixie tube showing 5, then press the key more than 3s till the second nixie tube start twinkling. After that, the parameter in second nixie tube changes every time as per the key press. At the same time, the load power will change as described in “modes and table of setting”. After that, please wait till the nixie tube stop to twinkling and back to the normal working mode.
