Note: If the detector is mounted in special environment where
there are slight dust or where it’s damp, seal the four

1. Steps:
1) Take off the protective membrane carefully on the surface of the
reflector and of the detector cover. Do not scratch or
contaminate their surfaces.
2) Remove the detector’s top cover, and power up the detector
with 24VDC. Two minutes later, put the magnet of commission
tool close to the reed switch (around the red LED) of detector’s
interface board. There may be two cases with the LEDs:
a. Green LED flashes.
b. Green LED illuminates continuously.
Take away the commission tool.
3) If Green LED flashes, it means the received light is quite weak
(the slower the flashing frequency, the weaker the received light
signal is). Tune the adjusting wheel and rotary rack on the
