Other Functions
(1) Automatic Compensation of Light
When dust exists in the working environment of the detector, the
transmitting window, receiving window and reflector may be covered
with dust, which will affect normal operation. In order to solve the
problem, the detector is designed with automatic compensation of light.
When there is dust on windows, the detector can judge the amount of
dust, and compensate the received signal through internal program
and circuit to ensure the detector can continue working normally. The
detector gives fault signal when dust on the lens and reflector surface
reaches a certain level and light compensation reaches the limit for the
detector to work normally.
(2) Self-diagnosis on Optical Signal
The detector has functions of checking transmitting, receiving and
amplifying circuit. When there is fault with these three parts of circuit
during operation, the detector will generate fault information.
VIII Troubleshooting
If the detector reports fault after long time running, please first check
if it’
s damaged. Make sure it’
s securely installed on the wall or other
fixed supporters. Then check the dust accumulation level and
position deviation to see if these has resulted in fault in automatic
compensation, and then consider other types of fault.
If the surface of the transmitting/receiving window or the reflector is
