INTRODUCTION

The manual you have in your hands is a guide for the correct use of the COMBI SPOHN remote control. This unit, together with the associated receiver, 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. This allows total safety in the use of the radio remote control.

To avoid unwanted operations, the system is provided with various security mechanisms that will be described in the next chapters. Any self-detection of anomalies blocks the execution of the operations.
The receiver works in the UHF band at 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 prescribed in the telecommunications regulations I-ETS 300 220.

GCFI VERSION
The GCFI (Intelligent Frequency Change Management) version provides the equipment with an intelligent system enabling it to change to vacant frequencies automatically and at random, thereby avoiding interferences that could cause continuous downtimes during operation.

ATTENTION!:
EVERYTHING RELATED IN THIS MANUAL TO THE CHANGE OF FREQUENCY AND THE WORKING CHANNEL, IS NOT VALID FOR THE GCFI VERSION.

GENERAL TERMS FOR THE CORRECT AND SAFE USE OF THE RADIO REMOTE CONTROL

• The user, in order to have maximum security in the handling of the remote control, must follow the rules described in this manual.
• The operator of the remote control, when he has to perform any command of the device, must be located in a place where he can visualize at all times the maneuver he is performing. If it’s impossible to do so, he must be located in a place where he can see the maximum possible manoeuvre, and in the hidden places, an assistant is required. Never perform a maneuver that may have an uncontrolled part.
• Do not leave the transmitter of the remote control on the floor or on top of metal blocks, in case you have to do it, activate the emergency stop (STOP BUTTON) of the transmitter and put the key/switch in its OFF position or lock the keyboard in if enabled (see section 2.1 – Keypad Lock Procedure).
• When the operator of the remote control ends his working day or has to leave the remote control, he must activate the emergency stop (STOP BUTTON) and place the battery in the charger for its recharging.

REMOTE CONTROL
This is a watertight (IP65) remote control panel made of highly resistant plastic material. On the front part, there are the pushbuttons and manipulators for manoeuvres, power switch, emergency stop button, and indicative LEDs, and on the back part it incorporates the housing for the interchangeable batteries.

The transmitter consists of three parts: buttons, control circuit and UHF transmitter/transceiver.

• The commands coming from the buttons are acquired by the microprocessor, which is in charge of elaborating the FFSK signal by adding the direction and control codes and injecting them into the UHF transmitter. The transmitter incorporates the signal of that command into the carrier frequency, which, previously filtered, will be emitted by the antenna.
• In the case of the models that incorporate the GCFI version, the transmitter becomes a transceiver in order to establish a two-way communication with the receiver.

DESCRIPTION OF MANOEUVRES
There are different control configurations adapted to each application. A document with the specific configuration for each application is delivered with the equipment.

Optionally, this range of remote controls can incorporate the following functions:

• Tandem/Trolley pre-selection: the transmitter can communicate with two different receivers.
• Pitch & Catch: operating mode in which several transmitters (between 2 and 4) and 1 receiver are associated.
• Master/Slave: operating mode in which 2 transmitters are associated with 2 receivers.
• IR Security: This infrared (IR) safety locking system makes it possible to limit the communication range to a certain area, disabling the maneuvers (Range Control) or preventing start-up (Start Control).
• Option Data Feedback: the transmitter and receiver use two-way communication, so the transmitter can receive information from the receiver and display it through the LEDs.
• NOTE: In case of incorporating any of these options, an annexed manual is provided.

LED INFORMATION
The various operating and fault diagnosis states are indicated by 2 LEDs:

On indicates that the remote control is transmitting.

GCFI versions: flashing rapidly or temporarily off indicates correct communication. If it remains on when a manoeuvre is activated, it indicates that there is no communication with the receiver.

| Battery status. You can see the indication details of this LED in section 5.2.2 of this manual.

NOTE:
You will find details of the information provided by the LEDs in section 10.

On some COMBI SPOHN remote control models, additional LEDs may be available to provide further information. The function of these LEDs can be found in the accompanying documentation that will be delivered with the special equipment.

BATTERY CHARGER
The charger is for indoor use. The charger allows a fast and safe charging of batteries. The batteries supplied are Ni-MH and the charger is designed to optimize their charge and life span. It’s capable of detecting defective, short-circuited or overheated batteries and can recover discharged batteries after a long period.

BATTERY CHARGING PROCESS
The charger has two indicator LED, one for power, which indicates that the appliance is connected to the power supply, and another for charging, which indicates that charging is in progress. When inserting the battery, the charger checks the charge level and can perform two actions based on it:

• If the charge level is low, a precharge is performed (LED flashing)
• A constant charging is performed for approx. 20 minutes (LED on fixed).

After this time, the charger verifies the state of the battery and adapts the load to each case. When the charging process ends, the LED turns off. A full charge takes approximately 4 and a half hour. Charging should be done at a temperature between -10 and 50 ºC.

Before using the remote control for the first time, make a full charge of the batteries.

INSTALLATION AND START-UP

INSTALLATION OF THE RECEIVER

• The details of the receiver installation can be found in the corresponding manual.
• It is indispensable that you consult the mentioned manual before starting up.

START-UP

• Once the receiver has been installed, by activating the main switch on the machine, the LEDs on the front of the receiver will light up to verify that it is working correctly.
• Insert a charged battery into the remote control and unlock the EMERGENCY STOP BUTTON. When the START button is pressed, the remote control will start working by activating the stop and start relays, and the general contractor will be locked. The LED on the remote control will be activated, indicating that the remote control is in work mode. From this moment on, pressing any button will activate the corresponding manoeuvre. The selected manoeuvre will remain active as long as the button is pressed.
• To keep the radio channel free and prevent the operator from accidentally leaving the machine running when not in use, the remote control has been fitted with an automatic stop system. If no action is taken, this system acts after 180 seconds (configurable), sending a stop sequence to the receiver, which will cause the machine to stop.
• When the machine stops, the frequency channel on which the device is working is displayed through pulses on the and LEDs of the receiver. The display begins with the tens pulses by the LED and continues with the units by the LED.
• In case that the value of tens or units will be zero, the display of this LED will be skipped. Further details of this channel display are given in Chapter 8.

SETTING THE TRANSMISSION TIME
The configuration of the automatic stop time (default 180 seconds) is done from the pushbutton panel, and this time can be changed between three values as follows:

1. Lock the STOP button and turn the on/off switch or key to the OFF position.
   ATTENTION!: REMEMBER THAT LOCKING THE E-STOP BUTTON IS THE SAME AS STOPPING THE REMOTE CONTROL, WHICH MEANS, DEACTIVATING IMMEDIATELY ANY RELAY OPERATED IN THE RECEIVER.

2. Operate any of the directions of the joystick marked as TIME in the following figure and, keeping it pressed, turn the on/off switch or key to the ON position.

3. Wait between 3 and 5 seconds approximately and unlock the EMERGENCY-STOP Button.

4. Release the TIME button and reactivate it.

5. The and LEDs will flash simultaneously one to three times indicating the time that has been 5)programmed, which can be :

   • Mode 1: 180 seconds (one flash).
   • Mode 2: 330 seconds (two flashes).
   • Mode 3: continuous emission (three flashes).

Repeat the sequence successively to change from one mode to another cyclically. To activate the transmitter again, press the START button.

BATTERY STATUS
The transmitter is provided with an indicator LED of the battery status. When the remote control detects that the battery is at a low level of charge (reserve status), the LED will start to flash and the horn manoeuvre will be activated intermittently: After approximately 10 minutes, the transmitter turns off, and sends a stop sequence to the receiver, and the LED lights on fix (battery empty). When the battery is in reserve, it is recommended to charge the battery.

ATTENTION!:
WHEN THE BATTERY IS IN RESERVE, IT IS NOT POSSIBLE TO PERFORM THE FOLLOWING FUNCTIONS: MODE FREQUENCY CHANGE, FREQUENCY CHANGE, KEYBOARD LOCK AND CHANGE THE AUTOMATIC DISCONNECTION TIME.

MAINTENANCE OF THE REMOTE CONTROL

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.

ATTENTION!:
IF ANY ANOMALY IS DETECTED IN THE OPERATION OF THE EQUIPMENT, IT MUST BE PUT OUT OF SERVICE IMMEDIATELY.

In order to increase the life of your equipment as much as possible, and avoid unnecessary repair costs, we recommend that you carefully follow the following conservation and maintenance tips:

• Avoiding unnecessary hits on the equipment.
• Use the attachment accessories, and shoulder strap, properly and adjust it so that the use of the equipment is comfortable and safe.
• Although the equipment has a high degree of water tightness (IP65), it shouldn’t be totally or partially submerged and shouldn’t be left in places where it could flood if it rains.
• The pushbuttons of the set are made of an elastic material to give them elasticity, texture and water tightness, so you must take special care to avoid touching them with sharp objects that could damage the structure of the button. When the button is worn out or damaged it must be replaced immediately.
• It’s also advisable not to leave the remote unnecessarily exposed to the sun’s rays.
• Check that the battery holder contacts are free of dirt and rust and that they exert the spring return force correctly.

ATTENTION!:
BEFORE ANY MANIPULATION PROCEED TO DEACTIVATE THE MAIN SWITCH OF THE MACHINE.

Generally, it’s advisable to carry out a complete revision of the water- tightness devices that protect both the receiver and the transmitter from bad weather conditions every now and then. It’s advisable that this revision is done by a Technical Assistance Service accredited by ITOWA, since bad waterproofing can cause irreparable damage to the equipment. In the case of the remote control, pay particular attention to the joints and rubber protections of the different drives, replacing them immediately if they have been cut or suffered other damages.

ATTENTION!:
ORIGINAL SPARE PARTS SHOULD BE USED FOR ANY REPAIRS, AND THE SAFETY FEATURES AS WELL AS THOSE OF THE UHF TRANSMITTER AND RECEIVER SHOULD NEVER BE ALTERED.

• To test the function of the active safety, simply actuate the EMERGENCY STOP BUTTON on the transmitter while it is running. The general contractor must fall down immediately.
• To check the operation of the passive safety, disconnect the power or remove the battery from the transmitter. The general contractor should drop after within a maximum of 1.6 seconds.

MAINTENANCE OF THE CHARGER
The following parts will be checked:

• Contacts (which must be free of dirt and rust)
• The correct display and indication of the LEDs.

If you have any questions or doubts, please do not hesitate to contact our Technical Assistance Service or any of our authorized technicians.

BATTERY CHARGING
The batteries included in the ITOWA equipment have no memory effect, which means that they can be put into charge without being completely discharged. For this reason, and in order to extend their useful life, it’s recommended to use one battery every half working day.

DISPLAY

DISPLAY OF THE EQUIPMENT CODE
In case you need to know the equipment’s code, the receiver allows you to display it. You can consult the manual of the receiver associated to this remote control to see the procedure that has to be followed, in order to see this code.

DISPLAY OF THE WORKING CHANNEL
It is important to know the frequency channel in which you are working to make a frequency change or to detect possible interferences from other equipment on the communication between the transmitter and receiver.

To know the frequency channel of the transmitter, please follow the below steps:

1. Activate the EMERGENCY STOP button.
2. Remove the battery or, if you have a key / switch put it on the OFF position.
3. Activate the START button and, keeping it pressed, move the switch/key to the ON position.
4. The frequency channel is then displayed by the LEDs and as follows:
   • First, the LED will flash as many times as tens have the frequency channel. In case it is zero it will not flash.
   • Then, the LED will flash as many times as the frequency channel has units. In case it is zero, it will not flash.
   • Once tens and units have been displayed, the transmitter can be started.

CHANGING THE WORKING FREQUENCY

CHANGING THE WORKING FREQUENCY (NOT VALID FOR GCFI VERSIONS)

• ATTENTION!: THE WORKING FREQUENCY SHOULD ONLY BE CARRIED OUT BY AUTHORISED STAFF.
• ATTENTION!: IF THE BATTERY HAS BEEN PUT ON STANDBY DUE TO LOW CHARGE, IT WILL NOT BE POSSIBLE TO SELECT A FREQUENCY CHANGE MODE OR CHANGE THE FREQUENCY.

OPERATION MODE
The system can operate in three modes:

• Mode 1: change of frequency disabled.
• Mode 2: change of frequency in manual mode.
• Mode 3: change of frequency in automatic mode.
  • ATTENTION!: THE EQUIPMENT IS DELIVERED WITH THE CHANGE OF FREQUENCY IN AUTOMATIC MODE.

Changing the operation mode:

1. Unlock the STOP BUTTON and turn the on/off switch or key to the OFF position. Press START and the joystick in UNITS (see Fig. 9 1) at the same time and, keeping them pressed, turn the key/switch to the ON position. The LEDs and will flash simultaneously from one to three times indicating the mode of operation that has been programmed, which may be:
   • Mode 1: change of frequency disabled (one flash).
   • Mode 2: change of frequency in manual mode (two flashes).
   • Mode 3: change of frequency in automatic mode (three flashes).
2. Without releasing the START button, each time the unit joystick is operated it will change the mode of operation successively from mode 1 (frequency change disabled) to mode 2 (frequency change in manual mode), to mode 3 (frequency change in automatic mode), from mode 3 again to mode 1 and so on.

The system works in the UHF band in the frequencies between 433.050 MHz and 434.775 MHz, or between 868.000 MHz and 870.000 MHz, depending on the model purchased, and complies with the requirements of the telecommunications and safety regulations I-ETS 300-220 (see section 9.5 CHANNEL ASSIGNMENT TABLE).

AUTOMATIC FREQUENCY CHANGE PROCEDURE

ATTENTION!:
TO PERFORM AN AUTOMATIC FREQUENCY CHANGE, THE AUTOMATIC FREQUENCY CHANGE MODE MUST FIRST BE SELECTED (MODE 3, SEE SECTION 9.1).

To change the working frequency automatically, proceed as follows:

1. If you are working with the remote control, as a safety measure, remove the transmitter battery to disconnect the equipment.
2. Insert a charged battery. It is not possible to change frequency with a discharged battery.
3. Make sure the receiver is ready for operation. The LEDs will display the following message, indicating that there is voltage and that it does not detect the channel occupied by another system:
   • ATTENTION!: PLACE THE TRANSMITTER AS CLOSE AS POSSIBLE TO THE RECEIVER.
4. If the STOP BUTTON is locked (pressed) it must be unlocked (released).
5. Press the START button (see section 9.1) to start the equipment and, keeping it pressed, lock the STOP button. The device automatically selects a new frequency and the new channel is sent to the receiver. The transmitter and the receiver will indicate the new frequency channel with the LEDs.
   To indicate this information on the transmitter, the and LEDs are used. First, there are as many flashes of the LED as the number of tens to be displayed, and then as many flashes of the LED as the number of units to be displayed. A very similar sequence occurs at the receiver: the LED indicates the tens and the LED the units.

If the frequency change has been made correctly the indicators and will stop flashing and the equipment is ready to work. If the frequency change is not successful, repeat the process until the receiver picks up a free channel.
After changing the working channel, in order to continue operating with the radio control, release the emergency stop button (STOP BUTTON) and press the START push button. In the receiver, the S1 indicator will activate, indicating that the stop and start relays are activated. As a consequence, the remote control is operating correctly and all manoeuvres can be performed.

MANUAL FREQUENCY CHANGE PROCEDURE

ATTENTION!:
TO PERFORM A MANUAL FREQUENCY CHANGE, THE MANUAL FREQUENCY CHANGE MODE MUST FIRST BE SELECTED (MODE 2, SEE SECTION 9.1).

To change the operating frequency in manual mode, proceed as follows:

1. If you are working with the remote control, as a safety measure, remove the transmitter battery to disconnect the equipment.
2. Insert a charged battery. It is not possible to change frequency with a discharged battery.
3. Check that the receiver is ready to work. The LEDs on the receiver will light up as follows, indicating that there is voltage and it does not detect the channel occupied by another system:
   • ATTENTION!: PLACE THE TRANSMITTER AS CLOSE AS POSSIBLE TO THE RECEIVER.
4. If the STOP BUTTON is locked (pressed) it must be unlocked (released).
5. Press the START button (see section 9.1) to start the equipment and, keeping it pressed, lock the STOP button. The illuminated indicators and from the transmitter will flash alternately. The receiver is waiting for the new working channel.
6. From this moment on, you will have one minute to introduce the new working channel. After this time, the device will exit the programming mode and will maintain the old channel, displaying the working channel through the LEDs on both the transmitter and the receiver, as described in the previous section.
7. Enter the channel number, e.g. 27, by pressing the joystick or by moving the corresponding remote Control to TENS twice and to UNITS seven times. Press VALIDATE. The selected channel is sent to the receiver, which will indicate the new channel via the LEDs, just like the transmitter.

The frequency change has been successfully completed and the indicators and will stop flashing. After the change of the working channel, in order to continue operating with the radio control, it is necessary to unlock the emergency STOP BUTTON and act on the START button. The indicator S1 on the receiver, if fitted, will light up permanently, indicating that the stop and start relays are activated and, consequently, the general contactor of the machine should be reset, and any manoeuvre can now be performed.

NOTE:
If the frequency change has been started in manual mode and the validate button is pressed without first entering the units or tens, the remote control unit will automatically select the first channel in the working band (see channel assignment table in section 9.5).

CHECKING THE SELECTED CHANNEL
After changing the frequency, it is advisable to check that the selected channel is not already occupied. Carry out the following operations:

1. Turn off the transmitter by pressing the STOP BUTTON.
2. If the channel is busy, the LED on the receiver will remain on, indicating that the channel is busy.

In this case, it is necessary to change the new transmitting channel as many times as necessary until we find a free channel. This will avoid abnormalities in the functioning of the machine.
