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 -
model number, technical characteristics, production date and serial number.
In the event of a complaint, please indicate the serial number (SN) displayed on the
label. An explanation of the symbols used on the label to abbreviate the technical
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:
1.
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
3.
Support can be of 2 types depending fro
suggested to make the cable exit below
o Surface flat / tilted –
with high resistance adhesive and suitable for weather or
fixed with a screw;
o Fix support
such as rod or similar where
with a screw.
4. Complet
e cable system and electrical connection to the station or control and
feeding apparatus following the schema on next page
clamps the cable to make it integral with the supporting structure
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
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.
