ILGA

Light grids

The fully automatic light grid with flat shape

The ILGA extends the ILG product range by a flat version turned through 90° which can be screwed or clamped on, in or behind a wall. It is also as „flat as a pancake“.

The ILGA is the only flat light grid on the market which in the lowest price segment combines an enormous range of different versions together with high technical capabilities. But there is no need to worry: first of all it is a perfectly normal light grid - simply connect and ready to use. Due to the free parameterability without auxiliaries you can, however, adapt the ILGA directly on site to most unforeseen installation situations and customer wishes, such as hiding one or more disruptive objects of any size in the light path, or inverting the function of the output. Illuminated ILGA, ILGA with heating, ILGA groups, adjustable buzzers etc. are also available.

ILGA light grids are used as reversing devices on doors and gates, in passenger lifts, on access openings in industrial production, in automatic stores, for the monitoring of cargo, etc.

Example: ILGA-LED, the ILG with integrated red-green LEDs for signalization of "door will close/closes/is open"

The version ILGA-LED is illuminated with red and green LEDs. The sensor strips are preferably mounted on the door leaves. When the door opens, or if it is already open, the ILGA-LED lights up in green to show that „everything is okay“. Before the door begins to close, it flashes several times in red to indicate „caution, the door is about to close“. When the door is closing, or if it is already closed, it remains red. If the door is closed for more than 60 seconds, the LEDs go off in order to save energy.

The ILGA-LED therefore offers additional safety and a „visible investment“ for your customer. It is particularly well-suited, for example, for retirement homes, hospitals and public buildings.

EN 81-20

The distance between the individual light beams is, directly at the sensor units, the same as the distance between the LEDs (channels). Owing to the triple crossing of the light beams, a higher resolution occurs in the centre section of the safe area than directly at the sensor units. In the drawing, the size of the clearly recognised objects is indicated with B, C, D, E. Thus, for the different light grid versions the following applies:

grid 12: B=118 mm D=59 mm C=39 mm
grid 06: B= 59 mm D=30 mm C=20 mm
grid 04: B= 40 mm D=21 mm C=14 mm

Acc. to EN 81-20 the light grid must recognize objects with a diameter of 50 mm (B in the drawing) at power-operated lift doors. Light grids with channel grid 04 meet the standards without restriction. At grid 06, cross beams must be parameterized (standard) and each sensor unit must be fitted recessed to min. A/8 from the edge of the door (E in the drawing), for example with a clear door width of 900 mm at least 113 mm. Channel grid 12 is not allowed with EN 81-20.

EN 81-20 is met when the light rays are between 25 and 1600 mm above the car door threshold. If you want to mount the light grid directly on the door edge, please use min. ILGA-42/04.

Acc. to EN 81-20 a failure of the light grid must be recognized. The default test input of the ILGA is available for it (see data sheet).

EN 81-70

The standard is met when the light rays are between 25 and 1800 mm above the cabin door threshold. Use for this purpose e.g. min. ILGA-31/06 or ILGA-46/04.
