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.
Radio remote control description 1.5 7 Safety function: stop protection The stop function brings the machine to a safe state every time it is necessary to stop it due to a potentially hazardous situation. Depending on the situation, this function can either be deliberately activated by the operator through the STOP pushbutton, or it is automatically activated when the radio link is incorrect or interrupted (the receiving unit autonomously stops the radio remote control). 1.
2 Risk assessment 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. The radio remote control can only be installed if this assessment gives positive results.
Risk assessment 2.1.2 9 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.
3 Warnings for installation 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.
Warnings for installation 3.3 11 Positioning the antenna The antenna is inside the receiving unit. Hence, install the receiving units 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 Group the wiring away from the electronic module, in order to avoid interferences and hazards related to electrical safety. Evaluate the radio remote control's wiring and remember that if the output dedicated to the machine's horn, siren or blinker is used for another command due to application's and/or functional reasons, some procedures in the “Configuration Menu” may result unavailable later on.
Warnings for installation 3.6 13 Testing The installer must check and complete the technical data sheet in all its parts, adding the date the system has been put into service, his stamp and signature. After installing and wiring the receiving unit, test the system “machine+radio remote control”, and check that the operations carried out correspond exactly to the commands sent (in particular check the STOP command).
4 Warnings for use 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.
Warnings for use 15 Visually and directly follow all movements of the machine and its load and remain inside the radio remote control working range. Pay particular attention to warnings and visual and acoustic signals, and take all measurements and steps to avoid that movements of the remote controlled machine may lead to hazardous situations for people and/or property. In case of malfunction, disable the system “machine+radio remote control” until the problem has been completely solved.
Radio remote control life cycle 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 17 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).
5.4 Radio remote control life cycle Radio remote control maintenance The following instructions provide information to safely carry out routine and special maintenance operations for the radio remote control. They shall be completed by: -- instructions provided by the machine manufacturer -- directions provided by the installer of the radio remote control on the machine -- regulations regarding safety at work and accident prevention in force in the country where the radio remote control is used.
Radio remote control life cycle 19 5.4.2 Daily routine maintenance Before starting to work: -- make sure that the transmitting unit panel symbols can be easily recognised and replace the panel if necessary -- check that the three plates on the transmitting unit are readable and intact -- make sure that the mechanical operation of the STOP pushbutton is correct.
Radio remote control life cycle 5.4.5 Special maintenance Special maintenance consists of repairs needed due to radio remote control failure, damage or malfunction, carried out with the aim of restoring the original usage and working conditions.
Troubleshooting 6 21 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.
