Any data reported in this table is not binding and may be susceptible to variations without notice.

4. ID PLATE AND MARKING DATA

NRS1 rain sensors have CE marking and comply with the Standards listed in the

Declaration of Conformity.

The plate data is displayed on an adhesive label placed on the outside of the casing,

which must remain intact and visible.

The main information it displays includes: manufacturer's address, product name -

characteristics is given in the table in the chapter on “TECHNICAL DATA”.

5. TECHNICAL INFORMATION

NRS1 rain sensor, to completely fulfil its task, has to be placed out in the open fully

exposed to any precipitation, possibly over the roof or in a similar position, or where

can be affected by rainfall.

Sensor can be connected to all stations or devices where signal processing is

foreseen or where a free contact signal is necessary (free from tension).

Feeding cable is 5 m long, made weather resistant, fire retardant and UV resistant.

6. ADVICES AND INSTRUCTION FOR MOUNTING

THESE INSTRUCTIONS ARE INTENDED FOR TECHNICAL AND SPECIALIZED PERSONNEL.

THUS BASIC SAFETY AND WORKING TECHNIQUES ARE NOT DISCUSSED.

To guarantee perfect function and facilitate installation, please note the following

indications and warnings:

Check that the cable length is sufficient to link to the station or control

apparatus. The eventual junction for extending the cable must be

sealed with a cable of the same type and colours.

Warning.

Check that the power supply is the same as those indicated on

technical data applied to the device.

To keep efficient and have a perfect functioning we suggest to clean the

sensitive part

at least any 6 months or any time is dirty due to smog, leaves,

impurity, etc.

Advices for sensor installation:

Choose the most suitable position where place the rain sensor. It has to be put

outside in direct contact with weathering.

2. The sensor is

placed slightly tilted (~ 20 °) to facilitate the flow of water, in a position

that does not have shelters to the fall of rain. Place it under the trees is not

recommended because it alters the natural weather event

Support can be of 2 types depending fro

5. Make a functional test.

To test a rain sensor is sufficient to wet (pour or spray water) on sensitive part of it; the

sensor transmits the signal of “wet sensor”. LED indicators of various apparatus should

light.

7.1. Replace P2 rain sensor on N series units

In the case of useNRS1 rain sensor to replace the old P2 on N series stations, during

connection phase operate as follows:

 RED wire connected at the place of WHITE wire;

 BLACK AND GREEN WIRES CONNECTED TOGETHER AT THE PLACE OF YELLOW WIRE;

 BLUE WIRE CONNECTED AT THE PLACE OF BLUE WIRE;

 PURPLE WIRE HAS TO BE INSULATED AND NOT CONNECTED.

8. DIP-SWITCHES SELECTION

In the sensor base, covered by a black cap, there is the access to dip-switches to

program the sensor which give the possibility of modifying status and sensitiveness.

Dip-switches meaning is the following:

DIP 1

DIP2

SENSITIVENESS

OFF

Maximum sensitiveness

ON OFF Medium-high sensitiveness

OFF ON Medium-low sensitiveness

ON ON Minimum sensitiveness

The sensor leaves the factory with the maximum sensitiveness set.

9. LED SIGNALS

Rain sensor has 2 signalling LED that indicate the functioning status.

 B - BLUE led flashing indicates that the sensor is fed.

 R - RED led lit fix indicates “wet sensor”; it has active command.
