USER'S MANUAL
1. INTRODUCTION
The manual you have in your hands is a guide to the correct use of the ITOWA multi-frequency MINI
TINY.
This transmitter is specially designed for remote control, without cables, Itowa receivers that act
directly on electromechanical drive machinery.
The radio signals employed use FM frequency modulation and FFSK coding. In the electronic design,
the most advanced technology and the latest generation microprocessors have been used, which
allow total safety of operation.
In order to avoid undesired manoeuvres, the transmitter is equipped with various safety mechanisms
which will be described in the following chapters. Any auto-detection of anomalies blocks the
execution of manoeuvres.
The transmitter works in the UHF band with frequencies between 433.050 and 434.775 MHz (UN 30
and 32 of the C.N.A.F.), or between 868.000 and 870.000 MHz (UN 39 of the C.N.A.F.) as stipulated
in the telecommunications regulation I-ETS 300 220.
Contact Itowa for other certificates.
GCFI VERSION
The GCFI (Intelligent Frequency Change Management) version is equipped with an intelligent system
that allows you to switch to unoccupied frequencies randomly and automatically, preventing
interference that can cause continuous stops during operation.
NOTE: EVERYTHING RELATED TO THE CHANGE OF FREQUENCY AND WORKING CHANNEL
IN THIS MANUAL IS NOT VALID FOR THIS VERSION OF THE DEVICE.

2. GENERAL INSTRUCTIONS FOR THE CORRECT AND SAFE
USE OF THE TRANSMITTER
In those applications where the operation of the system requires an operator, you must follow the
rules described in this manual.
Whenever the operator of the transmitter has to carry out any movement of the machine, he must be
located in a place where he can see at all times the manoeuvre he is performing.
If it is impossible to achieve this, you must place yourself in a position that allows you to see the
maximum possible manoeuvre and in hidden places you must use a signpost. Never carry out a
manoeuvre that may have an uncontrollable aspect.
Do not leave the radio control transmitter on the ground or on top of metal blocks, if necessary, lock
the emergency stop that has been set on the radio control and turn the machine OFF.
In the case of applications with an operator, when the operator ends his working day or has to move
away from the transmitter, he must activate the emergency stop system and turn the machine to the
OFF position.

3.1. GENERAL DESCRIPTION
The transmitter box incorporates the 48 / 115 / 230 Vac or 12 / 24 Vdc power supply inputs, the opto-
coupled digital input terminal block and the radio transmitter. Inside the transmitter box you will find
the electronics responsible for the radio transmission of the machine movements.
The commands coming from the different drives are acquired by the microprocessor, which is in
charge of elaborating the FFSK signal by adding the address and control codes and injecting it to the
UHF transmitter. The transmitter incorporates the signal of that order to the carrier frequency, which
previously filtered, will be emitted by the antenna.
As you can see from the block diagrams (Fig. 3.1. and Fig 3.2.), the transmitter consists of 4 parts:
Fig. 3.1. Block diagram of the UNIDIRECTIONAL transmitter.
Fig. 3.2. Block diagram of the GCFI transmitter.
For the GCFI models, the UHF transmitter becomes a transceiver in order to establish a bidirectional
communication with the receiver.

This is a non-watertight assembly (IP50 protection) designed mainly for a location in an electrical
cabinet or similar, protected from external agents and from humidity and dirt.
The mounting system of the transmitter, standard DIN-35 rail, does not require any adaptation
process, simply place it on the rail and apply light pressure.
The connection terminal block is located in an easily accessible position for connecting the
transmitter.

5. INSTALLATION AND START-UP
5.1. TRANSMITTER INSTALLATION
The transmitter has to be located in an accessible area so that it can be easily handled.
*It is recalled, in compliance with RD 171/2004 of Coordination of Business Activities, that you must
guarantee the safety conditions for the maintenance of the machine in issue, especially in its
accessibility and transit areas to the points where the operator must perform his work.
In applications with external antennas, the antenna should be free of metal shields in order to achieve
a better radio link and avoid communication cuts.
5.1.1. CTN MODEL FIXATION
Optional fixation
Figure 5.1. CTN model fixing
The magnetic fixation should be placed on a metal surface with a MINIMUM THICKNESS OF 4 MM
and where the two magnets make flat contact with the surface.

5.2. CONNECTION
It is recommended to connect the transmitter with a standard multi-cable hose. This hose will be
connected to the transmitter at one end through the Itowa terminal strip supplied for the CTN model or
to the terminal block for the CPH model, while at the other end a multi-pin connector will be placed,
identical to the one used by the machine to interconnect with its conventional button panel.

ATTENTION!: THE CONNECTION MUST BE MADE IN SUCH A WAY THAT WHEN THE
MAIN SWITCH IS DEACTIVATED, THE TRANSMITTER IS ALSO
DEACTIVATED.
ATTENTION!: AS A SAFETY MEASURE, IT IS ESSENTIAL TO ENSURE A GROUND
CONNECTION USING THE CORRESPONDING PIN ON THE
CONNECTOR.
Itowa is not responsible for improper installation.
5.4. START-UP
Once the transmitter has been installed, unlock the EMERGENCY STOP to start it up. The transmitter
leds will light up, as a test and the receiver will start to work activating the stop and start relays (if any)
and the general contractor of the machine will be interlocked. From this moment on, the activation of
any manoeuvre on the transmitter will lead to the activation of the corresponding relay on the receiver.
This selected relay will remain active as long as the manoeuvre remains active in the transmitter.

6. MAINTENANCE OF THE TRANSMITTER
The transmitter that you have purchased is made with top quality materials that ensure perfect
operation and functionality. Like any other machine or device, this transmitter requires a few basic
attentions that should be fulfilled. In order to increase the service life of your transmitter as much as
possible, and to avoid unnecessary repair costs, we recommend that you carefully follow the
following conservation and maintenance tips:
• Use suitable fastening accessories and adjust them in such a way that the use of the transmitter is
comfortable and safe.
• Avoid unnecessary collisions.
• It is advisable not to leave the transmitter unnecessarily exposed to the solar rays.
In general, it is advisable to carry out a complete revision of the waterproofing devices that protect
the transmitter from adverse weather conditions from time to time. It is advisable that this revision is
carried out by a Technical Assistance Service accredited by ITOWA, as improper waterproofing
can cause irreparable damage to the units.
ATTENTION!: BEFORE ANY MANIPULATION, DEACTIVATE THE MAIN SWITCH OF
THE MACHINE.
ATTENTION!: ORIGINAL SPARE PARTS MUST BE USED FOR ALL REPAIRS AND
UNDER NO CIRCUMSTANCES MUST THE SAFETY FEATURES OF
THE TRANSMITTER BE ALTERED.
For the maintenance of the transmitter, the following parts must be checked:
• The connection between the transmitter and the machine's electrical equipment.
• The correct operation of the active and passive safety circuits.
• The correct operation of all the leds through the startup test.
• Correct sealing of the transmitter cover and cable entries (Model CTN).
• The firm fixation of the whole set.
• If you have an external antenna, check that the connection is clean and free of rust. 13

 
MINI TINY
USER'S MANUAL
In order to check the functioning of the active safety, it will be enough to activate the EMERGENCY
STOP on the transmitter while it is running. The general contactor must fall immediately.
To check the function of the passive safety, disconnect the power supply or battery of the transmitter.
The general contactor should fall out after no more than 1.9 seconds.
ATTENTION!: IF ANY MALFUNCTION IS DETECTED IN THE OPERATION OF THE
TRANSMITTER, THIS MUST BE SHUT DOWN IMMEDIATELY.
For any doubt or question do not hesitate to contact our Technical Assistance Service or any of our
authorized technicians.
