Dear Customer, thank you for purchasing a MASTER S.p.A. product. This guide contains all the information you will need
concerning the use of this product.Read the instructions carefully and keep them for further consultation. The AT12 is a power
supply module for rain radio sensor; in addition to powering the sensor, the device is able to transmit to the associated receiver
devices, the signal of rain presence detected by the rain sensor. The module is designed to be associated with the rain sensor
X11. All other use beyond the field defined by MASTER S.p.A. is forbidden. This, as well as the breach of the instructions given in
this guide, shall release MASTER S.p.A. from any liability and shall annul the product warranty.

01. WARNIGS
Incorrect installation can cause serious injuries • Keep these instructions for future maintenance work and disposal of the product •
All the product installation, connection, programming and maintenance operations must be carried out only by a qualified and
skilled technician, who must comply with laws, provisions, local regulations and the instructions given in this manual • The wiring
must comply with current IEC standards • Certain applications require hold-to-run operation and can exclude the use of radio
controls or require particular safety devices.
WARNINGS FOR INSTALLATION
Check that the package is intact and has not been damaged in transit • The product is designed to be inserted inside of junction
boxes. The module does not provide any protection against water and only essential protection for contact with solids • It is
forbidden to install the module in areas not adequately protected, and near sources of heat • Install the product carefully, using
suitable tools • If there are several radio appliances in the same system, they must not be less than 1.5 m apart • Do not install the
product near metal surfaces • Do not modify or replace parts without the manufacturer's permission. Do not pierce or tamper the
box • The antenna cable carries line voltage. Do not cut the antenna cable as this would be dangerous. If the antenna cable is
damaged, replace the product.
WARNINGS FOR USE
Before operating the roller shutter/awning, make sure there are no people or objects in the area involved in its movement. Check
the automation during movement and keep people at a safe distance, until the movement ends • Do not operate the roller
shutter/awning when maintenance operations are being carried out (e.g. window cleaning). If the control device is automatic,
disconnect the motor from the power line.
02. ELECTRICAL CONNECTIONS
Make the connections with the power switched off • Check that the power line does not come from electrical circuits intended for
lighting • A circuit breaker or residual current device must be inserted in the power line. An isolating device with overvoltage
category III, namely distance between contacts of at least 3.5 mm, must be inserted in the power line • The product has no
protection against overloads or short circuits. Install a protective device in the power line that is appropriate for the load, such as a
fuse of max. 200 mA.

ALIMENTAZIONE
DI RETE
The module can be powered at 120 Vac or 230 Vac. The supply voltage must be applied to terminals 1 and 2.
The rain sensor X11 is equipped with a terminal block with 4 contacts. Terminals 1 and 2 of the rain sensor must be connected to
terminals 7 and 8 of the PS12 TX MIR (Contact neutral); terminals 3 and 4 of the rain sensor must be connected to terminals 5 and
6 (supply voltage). Terminals 3 and 4 of the module are not used. When you switch on the module, the LED lights up briefly.

Notes on radio systems
Do not use radio systems in places with strong interference (for example, near
police stations, airports, banks, hospitals). It is in any case advisable to carry out a
technical inspection prior to installing any radio system in order to identify possible
sources of interference. Radio systems can be used where any disturbances or
malfunction of the transmitter or receiver do not constitute a risk factor, or if such
factor is eliminated using appropriate safety systems. The presence of radio
devices working at the same transmission frequency (433.42 MHz) may interfere
with the radio receiver and reduce the range of the system, limiting functionality.

03. BUTTONS AND LED
433,42 MHz
On the back of the module there are two buttons (P1 and
P2) and a LED to use during the configuration procedures
04. MEMORIZATION - DELETION OF THE MODULE IN A RECEIVER DEVICE
01. Bring the motor connected to the receiving device in an intermediate position.
02. Press PROG of a transmitter already in memory in the receiving device for 5 seconds.
The motor performs two movements uphill.
03. Within 15 seconds, briefly press the P2 button:
the motor carries out 1 short upward movement if the sensor was stored
the motor makes 1 short downward movement if the sensor was deleted
05. OPERATING LOGIC
When rain sensor X11 detects the presence of rain, the contact across terminals 7 and 8 closes.
If the contact is closed for at least 2 seconds, the module performs some transmissions during which the LED lights. At the end of
transmission the LED will flash to indicate that transmission for rain presence have been made.
When the rain sensor X11 detects the absence of rain, the contact across terminals 7 and 8 opens.
If the contact is open for at least 60 seconds, the LED will stop flashing and the module AT12 is ready for new transmissions in case
of rain.
Manoeuvre associated with rain sensor
It's possible to select the type of movement (upward or downward) that must be commanded by the module in rain case.
The factory sets the module to command an upward movement.
To modify this setting:
- press the P1 button of module AT12 for approximately 4 seconds until the LED flashes, then release the button. The module
changes the operation associated with the presence of rain and back to the normal activities.
06. FAQ
? The module doesn't work.
- Check that to terminals 1 and 2 is present the mains voltage.
- Check that the power LED on the module lights up briefly.
? I can not store the module in the memory of the receiving device.
- Make sure that the receiving device operates with its hand-held transmitter.
- Make sure that the environment is not disturbed by other devices operating on the same frequency (eg radio headphones,
alarms, etc.).
- Be sure to correctly perform the storage procedure (see point 04).
- Bring the module near to the receiving device and redo the storage procedure (see point 04).
? The rain sensor is working properly, but the maneuver performed by the receiving device is not the one you want.
- Change the maneuver associated with rain sensor (see section 05).
