1. INTRODUCTION
This manual is a guide for the correct use of the ITOWA remote control set.
This set has been specially designed for the wireless remote control of all types of electro-mechanical
machinery.
The most advanced technology and the latest generation microprocessors have been incorporated in the
electronic design. This means total safety when using the radio control.
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.
2. GENERAL RULES FOR THE CORRECT AND SAFE USE OF THE
RADIOCONTROL
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.
Do not leave the radio control transmitter on the ground or on metal blocks. If you must do so, activate
the emergency stop (STOP BUTTON) of the radio control.
At the end of the working day, or if the radio control operator has to leave the radio control, he should
activate the emergency stop (STOP BUTTON) of the radio control and place the battery in the charger for
recharging.
Procedure to Lock the Keyboard
The equipment can have the option of keyboard lock on the transmitter by means of a system of
sequential lock/unlock of buttons. This system is similar to the one used to lock telephones
To lock the keyboard press the start button 5 times in less than 3 seconds, with the STOP BUTTON
pressed. Both leds and will light up for 3 seconds.
To unlock the keyboard, repeat the same operation, that is, press the start button 5 times in less than 3
seconds, with the STOP BUTTON pressed. The operation will also be indicated in the same way, that is,
both leds and will light up for 3 seconds.

We would point up that if your press the start push button when the transmitter is blocked, the led and
the led blink alternately.
In case the start button is pressed while the keyboard is locked, both leds will blink alternatively.

3.2. RECEIVER
The receiving unit consists of a cabinet, which houses the various electronic systems to receive
orders and activate/deactivate the corresponding relays for each manoeuvre of the crane.
The signal received by the antenna is injected into the receiver, which supplies a low frequency signal
in FFSK code to the microprocessor. The control module checks that the information received is free
of errors, and then draws up the corresponding order to activate corresponding relay.
For further safety, both the software and the hardware of all surveillance systems are double.

3.3. BATTERY CHARGER
The charger charges the batteries quickly and safely. The batteries supplied are Ni-MH, from which the
charger extracts their maximum power. It is able to detect faulty batteries, short circuits or overheating
and can recuperate batteries that have been flat for a long period of time.
The charger has 2 display leds, one for power supply indicating that the set is connected to the mains,
and the other indicating that the battery is being charged. When the battery is inserted, the charger
tests its level and then charges accordingly for approximately 20 minutes (led is on), or it keeps it
charged (led flashes), until it is fully charged (led is off). Complete charging takes less than 8 hours. For
safety purposes, the maximum charging time is limited to 12 hours.
Charging should be performed at a temperature of between -10 and 50ºC.

5.2. CONNECTING THE SET
It is recommended to connect the set with a standard multi-cable hose. This hose will be connected to the set
at one end, by means of the supplied Itowa connector, and the other end will be connected to a multi-pole
connector identical to the one used by the machine to interconnect with its pushbutton box.
5.3 . POWER SUPPLY OF THE RECEIVER
¡ATTENTION!: CONNECTION SHOULD BE MADE SO THAT WHEN GENERAL SWITCHING IS
TURNED OFF, THE REMOTE CONTROL RECEIVER IS ALSO TURNED OFF.
¡ATTENTION!: AS A SAFETY MEASURE ENSURE THAT IT IS EARTHED WITH THE
CORRESPONDING PIN OF THE CONNECTOR.
Itowa will not be held responsible for incorrect installation.
5.4. START-UP
Once the receiver is installed, when the general switch of the machine is turned on, the leds located on the
front of the receiver set will light up, for testing.
Insert a charged battery in the transmitter, switch off the STOP BUTTON and press the START button, the
remote control will start to operate by turning on the stop and start relays, and the general contactor will be
locked. The led and the S1 led (Start-up led) of transmitter will light up indicating that the remote control
is in operating mode. From this moment, if any button is pressed, the corresponding manoeuvre will be
activated. The selected manoeuvre will remain active while the button is pressed.
To keep the radio channel free and to avoid the operator from accidentally leaving the machine on when not
in use, the remote control is equipped with an automatic shutoff system. This system is activated after 180
seconds (this can be programmed) after not operating, sending a shutoff sequence to the receiver, causing
the machine to stop.
5.4.1. SETTING THE TRANSMISSION TIME
The automatic stop time can be set from the pushbuttons and can be changed between three values:
1) Lock the STOP BUTTON and remove the battery.
2) Press either of the first two manoeuvre buttons and keep them passed while you insert the battery.
3) Wait approximately one second and unlock the STOP BUTTON .

4) Release the manoeuvre button and then press it again.
5) The leds and will start to flash simultaneously from one to three times, indicating the set time,
which can be:
- Mode 1: 180 seconds (one flash).
- Mode 2: 330 seconds (two flashes).
- Mode 3: continuous transmission (three flashes).
Repeat this sequence to change from one mode to another in a cycle.
To activate the transmitter again, the battery should be removed and then inserted.
5.4.2. BATTERY STATUS
When the transmitter detects that the battery is at a certain level of discharging, the led will start to
flash and the horn will turn on intermittently (reserve). After about 10 minutes, the transmitter will switch
off and the led will be permanently on (flat battery).
6. MAINTENANCE OF THE RADIOCONTROL SET
The equipment you have purchased is manufactured using top quality materials to ensure perfect working
order and operation of the remote control. Similarly to all machinery and equipment, the remote control
requires minimum basic maintenance tasks that should be performed. In order to increase the life span
of the apparatus and avoid unnecessary repair costs, we advise you to carefully follow these preservation
and maintenance recommendations.
- Use the fastening accessories and shoulder strap suitably and adjust them so that the set can be
used comfortably and safely.
- The pushbuttons of the set are of elastic material to give elasticity, touch and water tightness, this
means that special care should be taken not to use sharp objects which could damage the structure
of the pushbutton. Replace the pushbuttons immediately if they are worn or damaged.
¡ATTENTION!: ORIGINAL SPARE PARTS SHOULD BE USED FOR ALL REPAIRS, SAFETY
SPECIFICATIONS OF THIS EQUIPMENT AND OF THE TRANSMITTER AND UHF
RECEIVER SHOULD NOT BE MOVED.

6.1. MAINTENANCE OF THE TRANSMITTER
¡ATTENTION!: BEFORE HANDLING THE TRANSMITTER, TURN OFF THE GENERAL
SWITCH OF THE MACHINE.
The good condition of the transmitter should be checked, paying particular attention to joints and rubber
protections of the various parts. Replace immediately is they have been cut or damaged as the result of
improper use of the apparatus.
Check the contacts of the battery holder ensuring that they are clean and free of rust, and that the spring
return force is correct.
6.2. MAINTENANCE OF THE RECEIVER
Maintenance of the receiver is identical to the transmitter. The following parts should be checked:
· The connection between the receiver and the electrical equipment of the machine.
· The correct working order of the active and passive safety circuits.
· The correct working order of all the leds display messages.
· The receiver cover and packing gland should be properly sealed.
· The firm fastening of the whole unit.
· If the antenna is exterior, check that the connection is clean and free of rust.
To check the working order of the active safety circuit, simply press the STOP BUTTON while the remote
control is on. The general contactor should drop immediately.
To check the working order of the passive safety circuit, remove the battery from the transmitter. The
general contactor should drop after within a maximum of 1.9 seconds.
6.3. MAINTENANCE OF THE CHARGER
The following parts should be checked:
Contacts (which should be clean and free of rust).
The correct display and indication of the leds.
¡ATTENTION!: IF YOU DETECT ANY ANOMALY IN THE WORKING ORDER OF THE SET,
IT SHOULD BE IMMEDIATELY SWITCHED OFF.
If you have any doubt or enquiry, contact our Technical Assistance Service or any of our authorised
technicians.

6.4. BATTERY CHARGING
The batteries supplied with ITOWA equipment do not have a memory effect, meaning that they can be
charged without having to be totally flat. Therefore, in order to lengthen their life span, it is
recommended to use one battery every half day of work.
7. DISPLAYING THE CODE
7.1. DISPLAYING THE CODE OF THE SET
If you want to know the code of the set, the receiver can display it by turning on jumper J1 of the base
plate.
To start displaying, place the jumper in the position indicated in the following figure:
The presentation sequence of the code will start through the LEDS. The hexadecimal value of each
group will be represented by a LED of the front panel of the receiver through a number of flashes equal
to this value, starting with LED S1 with the first digit of the code (reading from left to right).
The following table shows the correspondence between the hexadecimal value of each digit and the
number of flashes corresponding to the LED it represents.

Bear in mind that once the receiver detects the position of jumper J1, the test of all the LEDs is carried
out 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 better understanding of this process, an example of the code and the resulting display
is given. The code of the example is: 01A38E
