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.
1.7 Radio remote control description Protection against unintended movements from the rest position This function protects the system “machine+radio remote control” from unintended movements, namely machine movements not activated intentionally by the user, but resulting from possible electrical and mechanical failure of the radio remote control. Such function checks the neutral (rest) position of the actuators that control the machine's movements.
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.
Risk assessment 2.1.3 Protection from unintended activation The transmitting unit housing is manufactured so that it protects the actuators from unintentional activation, while meeting at the same time the operating needs, the comfort requirements and law limits. Assessment shall be made to establish possible additional protection measures for the actuators (i.e.
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.
Warnings for installation Fix the receiving unit in four points, using the specific holes in the housing. Do not perforate the receiving unit in any case. When installing on machines that vibrate, it is recommended to fix the receiving unit to the machine with the appropriate vibration dampers. 3.3 Positioning the antenna If this warning is disregarded, the radio remote control working range may be reduced. The antenna is inside the receiving unit.
Warnings for installation 13 WARNING: If the receiving unit is shielded by metal structures or is installed inside metal cabinets, use the appropriate extension kit for the antenna. In this case, install the antenna in a vertical position, and if possible towards the working area.
3.4 Warnings for installation Wiring The power supply of the receiving unit must be connected using an omnipolar switch with a switch-contact gap of at least 3 mm, that allows power supply disconnection during installation, wiring and/or maintenance operations. The receiving unit's power supply must be protected against short circuit by means of an external device (e.g. fuse, thermal magnetic circuit breaker).
Warnings for installation 15 Pay special attention to currents and voltages flowing in the SAFETY and STOP outputs: they shall not exceed the maximum permitted values (see technical data of the receiving unit). To obtain the protection from unintended movements from the rest position, connect the contact of the SAFETY relay in series with the movement commands. The STOP circuit in the receiving unit has two contacts connected in series through a wire jumper (manufacturer's standard wiring).
3.5 Warnings for installation At end of installation Make sure that during installation the protection measures on the radio remote control and/or in the machine have not been made ineffective by possible procedures carried out. 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.
Warnings for use 4 17 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.

All instructions for correct installation are given in "Part D" of the manual (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" of the manual (related to the transmitting unit).
Radio remote control life cycle 21 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 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.
Radio remote control life cycle 5.5 25 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.
6 Troubleshooting 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.
