Read Instructions

Assembly instructions: The rain sensor has bores in each edge of the bottom. By means of these 4 holes it may be screwed on a metal angle, a sun blind or the like. The screws that are used may only reach 16 mm at maximum inside the module bores. Please use sheet metal or plastic screws Ø 2.9 mm...3 mm. Mounting has to be done in such a manner that the gold-plated sensor surface is slightly inclined to-wards the points of the sensor surface enabling the water to flow off and preventing the water from staying on the sensor surface. The connecting cable will be led into a watertight switching outlet and wired up there. Please use a stabilised 12 V-power supply with a power of > 150 mA as current supply. The relay contact in the module may only be loaded up to 25 V and 2 amperes at maximum. In case you wish to control higher loads or larger voltages (e.g. 230 V~ motors), you have to interpose another relay approved for this breaking capacity. Setting into operation: After switching on the operating voltage of 12 V, the installed LED 1 lights up. If you put some drops of water on the sen-sor surface now, LED 2 lights up and the relay switches on. At the same time a sensor heating switches on which shall cause an accelerated drying of the sensor surface. This heating has a power of approx. 1 W and after a certain time it increases the temperature of the sensor sur-face by some degree Celsius compared to the ambient temperature.
If the sensor plate gets into contact with rain or slushy snow / hail, it switches on a relay. Sun blinds may be retracted with that, skylights may be closed or a simple rain alarm can be given. The automatically heated surface of the sensor prevents any freezing or wetting of the sensor surface. 2 installed LEDs indicate the function. Operating voltage: 12V=, current consumption: 8/120mA (without / with heating). Relay contact: 1 x ON, max. 25V 2A. Waterproof-encapsulated electronics.
