Rayrun N21 2-Wire CCT LED Controller User Manual

Rayrun N21 2-Wire CCT LED Controller User Manual

Introduction

N21 LED controller is designed to drive 2-wire tunable white (CCT) constant voltage LED products in voltage range of DC5-24V. With the RF remote controller, user can setup
LED brightness and color temperature with + – and shortcut keys.

Function & Size

Power supply input

Install positive power cable into the terminal marked with ‘+’ and negative power cable into the terminal marked with ‘-’. The controller can accept DC power from 5V to
24V, the output voltage is the same as the power supply, please make sure the LED rated voltage is same as the power supply.

Model: N21

Work status indicator

This indicator shows all working status of the controller.
It displays different events as following: Steady green:
Normal working. Single green blink: Command received.
Long single yellow blink: Brightness or CCT limit.
Red flash: Overload protection.
Yellow flash: Over heat protection.
Green flash 3 times: New remote controller paired

LED output

Connect LED loads to this terminal. Install LED positive cable into the terminal marked with ‘+’ and negative LED cable into the terminal marked with ‘-’. Please make sure
the LED rated voltage is same as the power supply and each channel’s maximum load current is in range of the controller’s rated current.
If the light color temperature is reversed from the remote controller operation, Please reverse the + and – cable to correct.

Wiring

Please connect the controller output to LED loads and power supply to the controller power input. The power supply voltage must be same as the LED load’s
rated voltage. Check all cables to be well connected and insulated before power on.

Functions

4. Turn ON / OFF

Press ‘I’ key to turn on unit or press ‘O’ key to turn off.
The controller will memorize the on/off status and will restore to the previous status on next power on.
Please use remote controller to turn on the unit if it was switched to off status before power cut.

5. Brightness control

Adjust light brightness. Press  key to increase brightness and press  key to decrease. The controller applies brightness gamma correction on dimming control and makes the brightness tuning more smooth to human sense.

6. Color temperature control

Adjust light color temperature. Press             key to increase color temperature and press key to decrease.

7. Brightness shortcut keys

Jump to the relative brightness level when press the corresponding keys.

8. Color temprature shortcut keys

Set the color temperature to full cool white, full warm white or neutral white which is 50% warm and 50% cool white.

9. Remote indicator

This indicator blinks when remote controller is working. The indicator will flash slowly when the remote battery is used out, please change the battery in this case. The battery type is CR2032 cell.

10.   Using the remote controller

Please pull out the battery insulation tape before using. The RF wireless remote signal can pass through some nonmetal barrier. For proper receiving remote signal, please do not install the controller in closed metal parts.

11.   Pair a new remote controller

The remote controller and receiver is 1 to 1 paired as factory default. It’s possible to pair maximum 5 remote controllers to one receiver and each remote controller can be paired to any receiver.
To pair a new remote controller, please operate with the following two steps:

• Plug off the power of receiver and plug in again after more than 5
• Press and  key simultaneously for about 3 seconds, within time of 10 seconds after the receiver powered

12. Keep current remote only

If one receiver is paired with several remote controllers and only one remote need to be kept, user can pair the current using remote for the second time, then the receiver will unpair all other remote controllers.

1.   Protection

The controller has protection function against output short circuit, overload and overheat. It will run into protection and stop working at these extreme conditions. The controller will try to recover working after a while once the working condition is good.
For protection issues, please check the situation with different indicator information:
Red flash: Check the output cables and load, make sure no short circuit and the load current is in rated range. Also the load must be constant voltage type.
Yellow flash: Check the installation environment, make sure in a rated temperature range and with good ventilation or heat dissipation condition.
