Operating Instructions (GB)
The product complies with the electromagnetic compatibility (EMC) requirements of the current European
guidelines. Conformity has been established and the relevant documentation has been deposited by the
manufacturer.
1 Mode of operation
The fixed transmitter TX-121 transmits the information of a potential free contact (i.e. sensors) and is
designed for a supply voltage of 4-16V
All receivers of the series SH-12 including the module CX-12 R are suitable with TX-121.
It must be noted that for applications or installations involving wireless transmission and which could have
an influence to safety of man or machine there may be a risk of unforeseen operation from extraneous
uncontrolled radio signals.
2 Safety Precautions
Please read, and abide by, the recommendations contained in these operating
instructions. Damage caused by incorrect application or by failure to follow these
operating instructions is not covered by warranty.
The manufacturer will under no circumstance be held responsible for further or consequential
damage that may be attributed to direct or indirect use of this product. All changes or
modifications not expressly approved by the manufacturer will void the warranty.
• For reasons of safety and conformity (CE) it is not permitted to modify or change parts of the product.
Repair or any kind of soldering on the circuit board is forbidden.
• The product should only be used in a case adequate for mains-voltage if applied!
• Electrical devices should be out of reach of children. Please be extra careful if children are around.
• For commercial use, compliance must be made with the recommendations and instructions of the
responsible regional/national authorities.
• Product operation and maintenance must be performed under the supervision of authorised, qualified
personnel.
• Opening the product and installation has to be performed by authorised electricians only.
• The product must not be installed or used in places where a risk of explosion may exist.
• TX-121 is a state-of-the-art product. However, there is a risk of danger if installation or operation is
performed by unqualified personnel
3 Preparation
Start installing the Transmitter-module CX-12 T, connecting the receiver carefully to the socket on the
board. Make sure the Transmitter is fixed and all Pins are connected well (solder them). Then solder the
antenna cable (173mm) in the appropriated pin (ref. Fig.)
Space must be enough to place all cables correctly and free from the electronic parts inside. Powered
wiring must not be mounted over the electronic board.
Ensure that the antenna is mounted as far as possible away from power wiring and is
not in contact with any powered part particularly in the terminal connection area.
For further description of functions and features, the correct preparation and tooling off the module is
expected.

4 Mise en service
Orienter l'antenne de sorte qu'elle se détache le plus possible de l’appareil.
Connectez la tension d'alimentation aux deux bornes (4,5 ... 16 V).
Tous les émetteurs de la série SH-12 doivent être programmés en fonction du bon récepteur. Pour plus
de détails, référez vous s'il vous plaît au manuel du récepteur. Pour déclencher un processus de
transmission, il vous suffit de faire un pontage entre les bornes à vis du contact à connecter et assurez-
vous qu’ une distance d'au moins 1mètre doit être maintenue entre l'émetteur et le récepteur.
La LED 1 clignote en témoin du contact radio avec le récepteur environ 3 fois / seconde pendant le
processus de transmission. Si l'émetteur ne reçoit pas de rétroaction du récepteur, la LED clignote
pendant environ 2 secondes très rapidement en signe que l'émetteur cherche le contact radio. Passé ce
délai, la transmission sera interrompue.
La LED 2 clignote plusieurs fois pour indiquer la rétroaction reçue par le récepteur au début et
à la fin du processus de transmission. Cette fonction (conjointement au CX-12 R) dépend du
réglage du module de réception.
Respectez impérativement les données techniques pour la mise sous tension ainsi que la polarité
en courant continu
