modularDIM Sensor DAYLIGHT

modularDIM Sensor DAYLIGHT

Ceiling sensor for detecting daylight in conjunction with the modularDIM DM expansion module.

The proDIM sensor DAYLIGHT light sensor measures the daylight entering the room through the window. Daylight controls proDIM KL3454 use this value for controlling the room lighting.

Design notes

The light sensor is exclusively for capturing the proportion of daylight in the room; The functionality of the daylight-based control depends essentially on the correct positioning of the light sensor:
• The light sensor has to be mounted looking freely in the daylight direction (window).
• Please, avoid the incidence of artificial light and direct sunlight.
• Distance between light sensor and window at most equal to window height: c ≤ a
• The light sensor is mounted in front of the window’s centre; distance between light sensor and window at most equal to window with: c ≤ b
• If the window lintel heights are much more than one sixth of the light sensor distance the light sensor must be suspended or inclined.
• Please, avoid larger shading of the light sensor’s angle of view, e.g. as a result of large window lintel heights, window cross bars or luminaire housings in front of the light sensor. Maximum shading allowed is 15 %.
• In case of different proportions – or if you have concerns about positioning the light sensor – please contact your sales office.
• A two-core cable (0.5–1.5 mm²) is used from the light sensor to the daylight-dependent control device. The maximum length allowed depends on the control device.
• If on account of awkward room geometry (too narrow or built up windows, shadowed ceiling, too large window lintel heights) the daylight at the light sensor is not sufficient for programming a daytime system point (see daylightbased control module) the light sensor can be switched to a higher sensitivity: Move the internal slide switch on the right next to the terminal for the light sensor line from the bottom position “5000” (dissolution corresponds to approx. 1 lx) to the top position “1000” (dissolution corresponds to approx. 0.2 lx).
