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 perfectly 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 from attack surface; in both cases is 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 to apply the metal bracket – provided –
with a screw.
4. Complete cable system and electrical connection to the station or control and feeding
apparatus following the schema on next page. Bind with one or more clamps the cable
to make it integral with the supporting structure.
5. If radio version is used, check rain sensor memorization has been done on control
device (Kato ADV Radio).
6. 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. ELECTRICAL CONNECTIONS
Electrical connections should be carried out in compliance with safety rules and
keeping in mind the meaning of various symbols and colours of the wires of the
feeding cable.

Sensor can work with any station unit or apparatus able to interpret its signal,
therefore the connections of the power cord are called in the specific instructions
of the central or equipment.

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.
10. RADIO CONTROL FOR CLOSING DUE TO RAIN (NRS1R)
The NRS1R radio rain sensor is a device capable of controlling the KATO ADV RADIO
motor remotely through a 433.92MHz signal.

7

THE RAIN SENSOR IS NOT FACTORY-PROGRAMMED (ASSOCIATED).
First follow the instructions provided below concerning the specific operation of the machines
you would like to control, then those of the actuator to be controlled (KATO ADV RADIO).
10.1. Saving the rain sensor on KATO ADV RADIO
The NRS1R rain sensor, as soon as it senses the presence of rain, transmits a unique signal
at the radio frequency 433.92 MHz. The NRS1R rain sensor can be used to control several
actuators, as long as the sensor is associated with the various KATO ADV RADIO actuators
and thus a window, with the procedure described below.
The encoding used varies for each channel, so each transmission will send a signal that is different
from all the others. It follows that the receiver must be able to recognize the enabled transmitters,
thus the transmission codes should be saved following the procedure below:
 Equip yourself with the NRS1R radio rain sensor, checking beforehand that it is working
and is powered properly (Blue LED flashing).
 On the KATO ADV RADIO actuator, briefly press (for about 1 second) the small “PRG”
button located near the terminal block. The slowly flashing LED indicates that it is waiting
to receive a valid radio code.
 Within 10 seconds, place the palm of your hand on the rain sensor (on the grey circular
zone) waiting for the Red LED rain indicator to start flashing.
 If the code is saved correctly, the LED on the KATO ADV RADIO actuator will emit one
long flash (1 sec.) as confirmation; then the LED will go out and remain at rest.
 If the code is not saved correctly - due to the memory being full, for example, or the
sensor being incompatible - the LED on the KATO ADV RADIO actuator will emit a series
of quick flashes for about 1 second; then the LED will go out and remain at rest.
