Microwave Sensor
EL-M0751
Manual
Welcome to use EL-M0751 Microwave Sensor!
The product is a new saving-energy switch; it adopts microwave
sensor with high-frequency electro-magnetic wave (5.8GHz),
integrated circuit. It gathers automatism, convenience, safety,
saving-energy and practicality functions. It works by receiving
human motion. 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.
Detection is possible through doors, panes of glass or thin walls.
SPECIFICATION:
Power Sourcing: 220-240V/AC Power Frequency: 50Hz
HF System: 5.8GHz CW radar, ISM band Detection Range: 180°
Ambient Light: <3-2000LUX (adjustable) Installing Height: 1.5~3.5m
Rated Load: 1200W (incandescent lamp) Transmission Power: <10mW
300W (energy-saving lamp) Time-Delay: min.:10sec±3sec
Power Consumption: approx 0.9W Max.: 15min±2min
Detection Distance:2- 12m(radius) adjustable
FUNCTION:
Can identify day and night: It can work in the daytime and at night when it is adjusted to the
“sun” position (max). It can work in the ambient light less than 3LUX when it is adjusted to
the “moon” position (min). As for the adjustment pattern, please refer to the testing pattern.
SENS adjustable: It can be adjusted according to using location; low sensitivity with 1m for
detection distance; High sensitivity with 8m, it fits for large room.
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.
Time–Delay is adjustable. It can be set according to the consumer’s desire. The minimum
time is 10sec±3sec. The maximum is 15min±2min.
NOTE: the high-frequency output of this
sensor is <10mW that is just one 100th of the
transmission power of a mobile phone or the
output of a microwave oven.
INSTALLATIION: (see the diagram)
Shut off power.
Loosen the screw on the bottom lid,
open the wiring hole, pass the wire
of power and load through the
bottom lid.
Fix the bottom lid with inflated screw
on the selected position.
Connect the power and load wire
into connection-wire column
according to the connecting figure.
Put the sensor on the bottom lid, twist the screw tightly then electrify it and test it.
CONNECTION-WIER SKETCH DIAGRAM
TEST:
Turn the SENS knob clockwise on the maximum. Turn the TIME knob anti-clockwise on the
minimum, Turn the LUX knob clockwise on the maximum.
When you switch on the power, the light will be on at once, and 5-30 seconds later will be
off automatically. Then if the sensor receives induction signal, it can work normally.
After 5-10sec of the first detection, the light could work again. If there is no induction signal,
the load should be stopped working within 5-15sec.
Note: when testingin daylight, please turn LUX knob to (SUN) position, otherwise the
sensor lamp could not work!
NOTES
:
The unrest objects can’t be regarded as the installation basis-face.
In front of the detection window there shouldn’t be hinder or unrest objects affecting
detection.
Avoid installing it near air temperature alteration zones for example: air condition, central
heating, etc.
In order to avoid the unexpected damage of product, please add a safe device of 6A when
installing microwave 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. Whether the indicator light is turned on after sensing? If yes, please check load.
c. If the indicator light is not turn on after sensing, please check if the working light
corresponds to the ambient light.
d. Please check if the working voltage corresponds to the power source.
The sensitivity is poor:
a. Please check the ambient temperature.
b. Please check if the signals source is in the detection fields.
c. Please check the installation height.
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 corresponds to the instruction.
d. If the air temperature changes near the sensor, air condition or central heating etc.
