Check the power wiring
The LED of the receiver doesn't light up Power f open circuitailure ( , short-circuit, etc.)
1.By reflecting, or light from other sources enter the
receiver
2.Both beams are not blocked at the same time
3.Response time is set too short
The LED of the receiver doesn't light up
when the light is blocked
1.Remove the reflecting object or change the
direction of beam
2. Block both beams at the same time
3.Prolong the response time
The receiver alarm indicator ON after the
beam is blocked, but there is NO alarm
signal output
1.Broken circuit or short-circuit of the wiring
2.Poor contact
1.Check the wiring and contact
2.Connect the cable
The alarm indicator of the receiver is
constantly ON.
1.The beam doesn't match closely
2.There is obstacle presents between the transmitter
and the receiver
3.The cover is polluted.
1.Re-adjust the beam
2.Remove the obstacle
3.Clear the cover
Intermittent alarm signal output
1.Improper wiring
2.The supply voltage does not reach 13V or higher
3.The potential obstacle appears to block the beams
due to the effect of wind and rain
4.The installation base unstable
5.The beam coincidence accuracy is inadequate
6.Beams blocked by other moving objects
7.Response time too short
8.Level 5 LED does not light up before the cover is
put on
1.Check the wiring
2.Check the supply power
3.Remove the obstacle or change the location
4.Select a site with a stable base
5.Re-adjust the optical axis
6.Adjust the shade time or change the install location
7.Re-adjust the response time
8.Re-adjust the optical axis, and make the signal
reception reaches its top.
