Measuring the intensity of outdoor lighting

The intensity of outdoor lighting (N.B.: it serves for the measurement of indirect illumination - it is not a sun sensor!) is measured by the RI-C-0401I module, which is designed as a separate wall-mounted module with a higher protection. In addition to the lighting sensor, the module also includes a terminated outdoor temperature sensor.

Inside the box is located the C-RI-0401S module, whose detailed description is given at the end of this manual, where the module C-RI-0401S is described. The actual sensor of lighting and temperature is connected to this module, which only needs to be connected to the CIB bus. This connection is enabled by the output of the C-RI-0401S module with a terminal block.

Fig. 1. A view the C-RI-0401I module (on the left is the module itself with the temperature sensor and a gland for the CIB cable, on the right is the housing with the light sensor), including the mounting holes.

Notes:

1. The box is equipped with 4 bayonet screws; the cap and the body of the box are connected with a cable.

2. Be cautious when handling with the internal circuits during the assembly and closing the box (to avoid damaging wires or squashing them under the lid when closing the module).

3. A standard cable for the CIB can be used as a supply cable, with regard to the placement.

4. When installing the C-RI-0401I module you must take into account the surge protection - avoid installation near the conductive grid of the lightning conductor, or close to large metal structures of the house (minimum distances must be observed) . If necessary, it is possible to install the over-voltage protection on the CIB bus on the zones boundary.

5. The temperature sensor in the module (the stem is 60mm) is the Pt1000 type, W₁₀₀ = 1.385.
