LX118B Infrared Motion Sensor Switch

The product is a new saving-energy switch; it adopts good sensitivity detector, integrated circuit and SMT. It gathers automatism, convenience, safety, saving-energy and practicality functions. The wide detection field is made up of up and down, left and right service field. It works by receiving human motion infrared rays. When one enters the detection field, it can start the load at once and identify automatically day and night; Its installation is very convenient and Its using is very wide. It has functions of power indication and the detection indication.

SPECIFICATIONS：

FUNCTION:

• Detection field: the detection field (see the following diagram) is made up of up and down, left and right service field, It can be selected according to the consumer’s desire. the orientation of moving has great relationship with the sensitivity；
• Can identify day and night: The consumer can adjust work ambient light. It can work in the daytime and at night when it is adjusted on the “sun” position (max). It can work in the ambient light less than 3LUX when it is adjusted on the “moon” position (min). As for the adjustment pattern, please refer to the testing pattern;
• Power and detection indication: The indicator lamp can flash one time every 4sec after switching on the power. It can flash 2 times every 1sec after it receives the signals. At the same time, it can show the sensor normal conditions for the detection and the power；
• Time-Delay is added continually: When it receives the second induction signals after the first induction, it will compute time once more on the basic of the first time-delay rest. (Set time).
• Time–Delay is adjustable. It can be set according to the consumer’s desire. The minimum time is 8sec±3sec. The maximum is 7min±2min.

Correct moving orientation		incorrect moving orientation

INSTALLATION （see the following diagram）

• Switch off the power；
• Screw off the nail on the bottom. Open the wire hole. The power wire and the load wire are bored in the bottom；
• Fix the bottom on the selected position with the inflated screw；
• Connect the power and the load with the connection-wire column according to the sketch diagram；
  So you can test it。

• Fix the sensor on the bottom, please screw the nail and switch on the power.

CONNECTION-WIRE DIAGRAM（see the right figure）

TEST：

• Turn the light-control knob clockwise on the maximum(sun), turn the time knob clockwise on the minimum；
• When you switch on the power, the load doesn’t work and the indicator lamp flashes one time every 4sec. After 5~10sec, the load work and the indicator lamp flash two times every 1sec. Under the conditions of no induction signal the load should stop working within 5~30sec, the indicator lamp should flash still one time every 4sec;

• After the first is out, make it sense again after 5~10sec. The load should work and the indication flash speed is two times every 1sec. The load should stop working within 5~15sec;
• Turn ambient light knob anti-clockwise on the minimum. If it is adjusted in the less than 3LUX, the inductor load should not work after load stop working. If you cover the detection window with the opaque objects (towel etc), the load work .under no induction signal condition, the load should stop working within 5~15sec；

NOTES：

• Electrician or experienced human can install it；
• The unrest objects can’t be regarded the installation basis-face；
• In front of the detection window there shouldn’t be hinder or unrest objects effecting detection.
• Avoid installing it near air temperature alteration zones for example: air condition, central heating, etc
• For your safety. Please don’t open the case if you find hitch after installation.
• In order to avoid the unexpected damage of product, please add a safe device of 6A when installing infrared sensor, for example, fuse, safe tube etc.

SOME PROBLEM AND SOLVED WAY

• The load don’t work：
                a.Check the power and the load；
                b.If the load is good；
                c.If the indicator lamp speed quicken after sensing;
                d.Please check if the working light correspond to the ambient light。

• The sensitivity is poor：
                a.Please check if in front of the detection window there are hinder that effect to receive the signals。
                b.Please check the ambient temperature;
                c.Please check if the signals source is in the detection fields;
                d.Please check the installation height;
                e.If the moving orientation is right.

• The sensor can’t shut automatically the load:
                a.If there are continual signals in the detection fields;
                b.If the time delay is set to the longest;
                c.If the power correspond to the instruction.
                d.If the air temperature change near the sensor, for example air condition or central heating etc.
