Functional Description
SENSOR – CONSTANT LIGHT CONT MOTION SENSOR
Function Description:
The integrated constant light controller ensures that the luminaire adapts automatically to the ambient
brightness, i.e. it only provides as much light as is actually required. The integrated motion sensor switches
the luminaire on or off depending on whether it detects a presence. The brightness can be individually ad-
justed at any time without having to intervene with the programming. In this case, the luminaire is operated
as described under DIMMER SWITCH. The “new” brightness setting is thus temporary and is only maintained
for as long as the luminaire is switched on (to save this light level permanently, see SAVING THE LIGHT
LEVEL, pages 9 - 10)
Other Functional Features
• If there is sufficient ambient light, the luminaire remains switched off even if motion is detected.
• If there is sufficient ambient light, the luminaire switches itself off and remains switched off until the light
level drops below the preset intensity.
• If the luminaire is switched off manually using the switch, the luminaire remains switched off as long as no
motion is registered within its detection range for a period from 5 to 30 minutes (depending on setting –
factory setting: 15 minutes). No motion will be detected within the detectable range. Only after this period
has elapsed does the luminaire automatically switches itself on again if motion is detected.
• If the power supply is interrupted, such as in the case of changing power sockets, the luminaire will switch
back on when the power supply is resumed even if nobody is within the detection range and the luminaire
was previously switched off.
• When the luminaire is switched on, it always comes back on at the set brightness level.
