Original instructions Air series User manual Description, warnings and instructions LIAIRE01-01
Warnings and caption for the documentation attached to the radio remote control The attached documentation is an integral part of the radio remote control and it aims at providing the instructions needed for using and maintaining the system, paying particular attention to the safety functions.
Three symbols are employed throughout documentation, which are used to highlight specific safety-related issues. They are classified according to the hazardous situation that may arise and on the possible consequences: Symbol If the highlighted instructions are not respected ... ... a dangerous situation will occur… ...consequences for people may be… ...consequences for property may be… …highly probable. … critical (death or physical damage). … critical. … probable.

Radio remote control description 1 Radio remote control description 1.1 How the radio remote control works Industrial radio remote controls are used to control machines from a distance, without physical connection between the user and the machine (i.e. wires or connecting cables). They consist of a portable transmitting unit, from which the user remotely controls the machine, and a receiving unit installed on board the machine itself. 1.2 Technical Data Command response time (typical) .............
Radio remote control description 7 1.4 Radio link The transmitting unit constantly communicates with the receiving unit through a radio link. This is an essential requirement to ensure safety for the radio remote controlled machine. The two units use messages coded through an address that is unique (produced by Autec only once) and univocal (specific for each radio remote control). Each unit can only decode messages coming from the unit with the same address.
1.8 Radio remote control description Identifying the radio remote control As required by standard IEC 60204-32, each radio remote control is uniquely identified through a serial number (SERIAL N. or S/N). The serial number is provided in the identification plate on each radio remote control unit. This is the only reference to be used both for maintenance operations and for declarations to competent bodies.
Risk assessment 9 2 Risk assessment When using and installing an industrial radio remote control it is therefore always necessary to evaluate if the machine can be radio remote controlled. In fact, as required by standards ISO 12100 and ISO 14121, all machines must undergo risk assessment and related analysis. The radio remote control can only be installed and used if this assessment gives positive results.
2.1.2 Risk assessment Delay in command response time Due to the characteristics of radio propagation (i.e.: EM interference, outof-working-range condition), a delay up to the "Maximum stop time" may occasionally occur from the moment a command in the transmitting unit is released to the moment its corresponding output in the receiving unit is deactivated.
Warnings for installation 3 11 Warnings for installation Besides instructions established by the machine's manufacturers, installers must always observe the following warnings. 3.1 General Respect and enforce the provisions of all reference standards relevant in the concerned application field (i.e. IEC 60204-32 for hoisting machines.) Always follow the instructions provided in the technical data sheet and respect values given in the technical data to carry out correct installation.
3.3 Warnings for installation Positioning the antenna The antenna is inside the receiving unit. Hence, install the receiving unit towards the working area, so that shields, structures or materials do not obstruct the radio link. In particular, the receiving unit must be placed at least 50 cm far from metal objects in its surroundings and never inside closed metal containers.
Warnings for installation 13 The STOP circuit in the receiving unit has two contacts connected in series through a wire jumper (manufacturer's standard wiring). If the machine needs a STOP circuit with two separate contacts (four wires), this bridge can be removed. In this case, the installer is responsible for wiring in a way that assures the required safety level. Group the wiring away from the electronic module, in order to avoid interferences and hazards related to electrical safety.
Warnings for installation Look up in the technical data sheet and check that the frequency band set in the radio remote control is permitted in the country of use. Correctly close the receiving unit so that the protection degree from dust and water is not jeopardised: check that the gasket is intact, correctly put the housing parts one over the other so that they overlap, and tighten the screws. 3.
Warnings for use 4 15 Warnings for use In addition to all instructions provided by the machine manufacturer, by the installer of the radio remote control and by the person responsible for the safety of the work area, users shall always respect the following warnings. 4.
4.2 Warnings for use During normal operation Pay attention to the entire work area. Immediately press the STOP pushbutton when a hazardous situation occurs. Visually and directly follow all movements of the machine and its load and remain inside the radio remote control working range.
Radio remote control life cycle 17 5 Radio remote control life cycle To ensure safe and long-lasting operation of industrial radio remote controls, carefully follow the instructions provided for each stage of the product life cycle. 5.1 Transportation and storage Radio remote controls must always be transported and stored inside their packing until they are installed on the machine. Environmental transportation and storage conditions are given in the following table.
Radio remote control life cycle All warnings for correct installation are given in chapter 3. All instructions for correct installation are given in "Part D" (related to the receiving unit). 5.3 Use The use of industrial radio remote controls is strictly limited to skilled and properly trained personnel. All warnings for correct use are given in chapter 4. All instructions for correct use are given in "Part C" (related to the transmitting unit).
Radio remote control life cycle 19 In case of malfunction or damaged parts, disable the system “machine+radio remote control” until the problem has been completely solved. After each maintenance operation, if a unit has been opened, close it correctly, in order not to endanger its protection degree from dust and water: check that the gasket is intact, correctly overlay the two parts of the housing and tighten the screws. 5.4.

Radio remote control life cycle 21 5.4.6 Preventive replacement of actuators (joysticks, pushbuttons and selectors) Each actuator on the transmitting units can be used for a maximum number of operations. Replace joysticks, pushbuttons and selectors on the transmitting unit before they reach the maximum number of operations, even though they are still working. Replacement prevents possible failures that may lead to loss of safety. Actuator Max. operations Actuator Max.
5.5 Radio remote control life cycle Machine maintenance Follow instructions provided by the machine manufacturer and by the installer of the radio remote control, in order to carry out machine maintenance. When carrying out maintenance on the machine, always disconnect power supply from the receiving unit. In the event of necessary maintenance on the machine (i.e. soldering), disconnect all the electrical connections of the receiving unit. 5.
Troubleshooting 6 23 Troubleshooting When the radio remote control does not work: -- bring the transmitting unit close to the receiving unit to avoid radio interference and disturbances -- establish whether the problem lies with the radio remote control or with the machine. Therefore, before any inspection, try to control the machine from a control unit different from the radio remote control, if present. If the problem persists, it lies with the machine.
