RoHS compliant.
Settings
Detection range
Detection range can be reduced by selecting the combination on the DIP switches to fit precisely each application.
Hold-time
Hold-time means the time period to keep the lamp on 100% after motion detected.
*when hold-time set as 3s, sensor enters into test mode, this test mode is mainly for users to choose the desired detection range. In this mode, the daylight sensor is disabled, when there is no motion, fixture keeps off, when there is motion detected, fixture keeps a cycle of 3s on and 2s off.
Daylight sensor
Daylight sensor means the daylight threshold to enable or disable the sensor function.
"Disable": The sensor works always, even during daylight.
w50lux": The sensor works only in twilight.
w10lux, 2luxw: The sensor works only in the dark.
Stand-by period
This is the time period that the lamp remains at a low light level before it is completely switched off in the long absence of people.
?+? means bi-level dimming control, the fixture never switch off.
Stand-by dimming level
This is the dimmed low light level you would like to have after the hold-time in the absence of people.
Daylight monitoring function
Utilizing the Dual-PD technology, this sensor can tell the difference of natural light and artificial light(lamp) from behind the diffuser, switch on automatically(even without movements) when the ambient light is below target value, and then switch off automatically whenever the artificial light is not required(ambient light is bright enough).
This is the REAL & INTELLIGENT daylight monitoring sensor for built-in installation.
Note: Lux-Off sampling time?30s; Lux-On sampling time?10s.
Lux-On function takes effect only when standby dimming period set at.
