Multi sensor HF DIM MULTI
[attachment=30862]
Range of application
HF DIM MULTI works in connection with fluorescent lamps and compact fluorescent lamps with
electronic ballasts with an 1...10 V interface.
It comprises a constant-light control and a presence detection in one unit. Both in light stabilising and
presence detection it provides a gliding light control. Utilising photosensors, the daylight is only
supplemented by the amount of artificial light required to reach the preadjusted target of intensity.
Motion sensors adjust the artificial light in a sliding manner to the target light level when someone
enters the room and dim it again in the same way when the room is being left. After a delay time the
light is switched off.
The HF DIM MULTI is wired to the low-voltage interface as well as to the supply side (L and N). Its
output can directly be used for the ON/OFF switching of the electronic ballasts.
Operation
HF DIM MULTI is well suited for public, industrial and private rooms. The control maintains constant
illumination at a pre-set light value. The integrated presence detector ensures that the light will only
become intense if a person enters the area of detection.
After the target light level has been set only the amount of artificial light required for achieving this
target is added to the daylight. If there is enough daylight the lamps are switched off (delay-time: max 3
min). Furthermore, the presence detection adjusts the artificial light up or down (within the detection
area of the sensor) in a gliding manner so that, in addition to the energy saving effect, also a gentle
treatment of the lamps and thus an extension of their service life occurs. An additional push-button for
switching-on can be used.
The presence detection may be deactivated (O/I). In this case the lamps are always switched on if
there is not enough daylight. To avoid an unintended switching-on at night a monitoring switch should
be used (Alternative 4).
Area of detection and extension of presence detection
The presence detection has an acquisition range of approx. 100°. It surveys an area of approx. 7m in
diameter if the height of the room is 3 m.
If a larger area is supposed to be jointly surveyed the presence detection of several controls may be
connected to each other (Alternative 2+3). In this case, each control can work individually as a
constant- light control in its area. The presence detection, however, is done jointly for the whole area of
the room. It is sufficient, if one of the controls recognises a movement (Alternative 2).
Vice versa, all controls may be individually employed for a differentiation of the area of detection
(Alternative 3).
Construction, assembly and wiring
HF DIM MULTI can be mounted on ceilings or can be clipped on T8 or T5 tubes.
The mounting plate of the surface control is fixed by screws on the ceiling and then wired.
Consequently just the function part is fixed to the wired mounting plate. Function part and mounting
plate are strictly separated from each other.
With the attached clips the sensor can be mounted to lamp fixtures with a minimum inner width of 60
mm. The clip is to be fixed to the button of the sensor and would be snapped-on the lamp tube with a
diameter of 26 mm or 16 mm. The clip should be fixed to one end of the tube in order to avoid a too
high unit load. The clip can be adjusted to the different depth of the lamp fixtures through a more or
less deep fixation. It now can be wired.
Wiring instructions
The actual light intensity as actual value for the constant light control should always be picked up by
the sensor indirectly at the point of reference. Direct light on the sensor from the interior illumination or
the illumination of the place of work is to be avoided.
The optics of the presence sensor are designed for a ceiling height of 2.5 m to 3.0 m. In higher rooms
the density detection of the sensor diminishes.
It is best to wire the control in such a way that the intensity adjustment trimmer points in the direction of
the window. This will inevitably align the detection area of the photosensor correctly with the room. The
mounting into a draught (e.g. close to a ventilator or air-conditioner) should be avoided.
