Transmitter light does not shine
It may be inappropriate because the power supply voltage (disconnection, short circuit, etc.), Solution: Check the power line indicates no light receiver <br> <br>
May be inappropriate because the power supply voltage (disconnection, short circuit, etc.), Solution: Check the power supply wiring with the light intercepted, the receiver does not light <br> <br> alarm indicator may be because:
1. Because the reflected light enters the transmitter or receiver 2. The other two light beams are not simultaneously blocked 3. The light-shielding time is set too short <br> <br> Solution:
1. Remove the reflecting object or change the direction of the optical axis 3. The two beams 2 simultaneously blocking time after interrupting the light shielding extended, alarm indicator light receiver, but no alarm signal output <br> <br> may be because:
1. 2. Wiring open or short circuit poor contact <br> <br> Solution:
Check the power line or node intermittent alarm signal output <br> <br> may be because:
1. 2. emission axis does not coincide with an obstacle contaminated by dirt cover 3. Solution <br> <br> between the reception:
1. Re-adjust the optical axis 2. Remove the obstacle 3. Clean the housing receiver warning light lit <br> <br> may be because:
1. bad 2. Wiring supply voltage below the operating voltage 3. emission, the mounting base labile obstacle 4. 5. 6. Other optical axis coincides with insufficient precision of the moving object between the light shielding <br> <br> receiving solution :
1. Check the wiring 2. Check the power supply 3. Remove obstacles or change the installation location 4. Select a place with a solid foundation 5. Re-adjust the optical axis 6. Adjust the light-shielding time or change the installation location Optical axis display voltage repeats <br > <br> reasons:
1. The switching power supply housing to optical axis misalignment poor ground 2. 3. The signal is too weak <br> <br> Solution:
1. Housing ground 2. Adjust optical axis 3. Replace long-range infrared detector

Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. This powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
Just because of the pigments, our world become colorful!
