1. INTRODUCTION
The manual you have in your hands is a guide for the correct use of the multi-frequency receiver IT3R10.
This receiver, together with the associated remote control, has been specifically designed for the wireless
remote control of electromechanically operated machinery.
The radio signals used employ FM frequency modulation and FFSK encoding. The most advanced
technology and the latest generation microprocessors have been used in electronic design.
To avoid unwanted operations, the receiver is provided with various security mechanisms that will be
described in the next chapters. Any auto-detection of anomalies blocks the execution of operations.
The type of transmission used, GCFI (Intelligent Changing Frequency Management) provides the
equipment with an intelligent system enabling it to change to vacant frequencies automatically and at
random, thereby avoiding interferences which could cause continuous downtimes during operation.
The receiver works in the UHF band at frequencies between 433,050 and 434,775 MHz or between
868,000 and 870,000 MHz as prescribed in telecommunications regulations I-ETS 300 220.
Contact Itowa for other certificates.
2. GENERAL TERMS FOR THE CORRECT AND SAFE USE OF RADIO
REMOTE CONTROL
For maximum safety when handling the radio control, the user must follow the rules indicated in this
manual.
Whenever the crane has to be manoeuvred, the radio control operator must be in a place where he can
view the whole manoeuvre being performed. If this is not possible, he should position himself where he can
see as much of the manoeuvre as possible, and coordinate with another person when he cannot see
properly. Never perform a manoeuvre which may be partially uncontrolled.
When the operator finishes his work on the receiver, he must activate the emergency stop (STOP
BUTTON) of the transmitter and must take care not to leave the machine control accessible to
unauthorized personnel.

5.3. START-UP
Once the receiver is installed and connected, when the general switch of the machine is turned on, the
LED located on the front of the receiver set will light up, to verify its correct operation
The following steps will be done with the transmitter associated with the receiver:
Insert a charged battery into the transmitter set, release the STOP BUTTON and press the START1) button.
The remote control will start to work activating the stop and start relays of the receiver, and the2) general contactor will be locked. The LED on the transmitter and receiver will start to flash and the
S1 LED on the receiver will be activated, indicating that the radio control unit is in working mode.
From this moment, if any button is pressed, the corresponding operation will be activated. The3) selected operation will remain active while the button is pressed.
To keep the radio channel free and to avoid the operator could accidentally leave the machine on when it
is not in use, the remote control is equipped with an automatic stop system. This system is activated after
180 seconds (it can be programmed) after not operating, sending a stop sequence to the receiver,
causing the machine to stop.

7. DISPLAY THE EQUIPMENT CODE
The code of the equipment is a unique hexadecimal code shared between the transmitter and the
receiver, and identifies and links them by radio frequency.
In case you need to know the equipment code, the receiver allows its display by acting on jumper J1 on
the motherboard.
To start the display, place the jumper in the position indicated in the following image:
Detail of jumper J1 to show the equipment code
At this point, starts the code display sequence through the LED, The value in hexadecimal of each
number will be represented by a LED on the front panel of the receiver by a number of flashes equal to
that value, starting with LED S1 with the first digit of the code (reading from left to right).
The following table indicates the correspondence between the hexadecimal value of each digit and the
number of flashes that will correspond to the LED that represents it.

Note once the receiver detects the position of jumper J1, the functional test of all LEDs begins, without
interruption. Between the presentation of one LED and another, all the LEDs flash as a separation mark.
If the position of jumper J1 is changed during the test, the sequence is not interrupted. For a better
understanding of this process, we propose an example of code and the result of its display.
