How the radio remote control works
1 Description of the AIR series' radio remote controls
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.
The two units constantly communicate with one another through a radio link. They automatically search for a free working frequency.
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).
1.2
Applications
AIR series' radio remote controls can be installed on hoisting and material handling machines
(i.e. overhead cranes).
As required by standards ISO 12100 and ISO 14212, risk assessment must be carried out
for each machine (see chapter 3). The radio remote control can only be used if this assessment gives positive results. However, this radio remote control cannot be installed:
- on machines installed in places where equipment with explosion-proof characteristics is required
- on machines for moving, raising and transporting people.
- on machines that may generate dangerous situations if they stop due to the loss of radio
link

Safety Functions
Autec radio remote controls are equipped with some functions that provide high safety levels,
in order to safeguard the safety of people and property.
1.4.1 Stop
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 ac-

tivated when the radio link is incorrect or interrupted (the receiving unit autonomously stops
the radio remote control).
1.4.2 Protection against unintended movements from the standstill position (UMFS)
This safety 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 safety function checks the neutral (rest) position of pushbuttons controlling the machine's movements. Each time one of those pushbuttons is operated, the transmitting unit
sends both the movement command and the SAFETY command.
1.5
Identifying the radio remote control
As required by standard IEC 60204-32 , each radio remote control is uniquely identified
through a serial number (S/N).
The S/N is provided in the identification plate in the two units.

3 Risk assessment
Always evaluate whether the machine can be radio remote controlled. In fact, as required by
technical standards specific to the market where the system “machine+radio remote control”
is used, each machine must undergo risk assessment and risk analysis.
The radio remote control can only be installed if this assessment gives positive results.
The machine manufacturer and/or the person who decides upon radio remote
control installation and use is responsible for this risk assessment.
Autec cannot be held responsible if this assessment has not been carried out correctly or is incomplete.

Risk assessment
Risk assessment for radio remote controlled machines
If required by the risk assessment, draw up protection measures to prevent, reduce and report potential hazard situations.
3.1
Risk assessment for radio remote controlled machines
When carrying out risk assessment for the machine or for the system where the radio remote
control is installed, the following must be considered:
- some machines cannot be radio remote controlled: check for forbidden applications (see
paragraph 1.2)
- the radio link between the two units may be interrupted due to persistent disturbance or
interference.
- all warnings related to installation, use and maintenance provided by Autec must be taken
into account
3.1.1 Aspects related to radio link
Whenever the radio link is interrupted (i.e. stop, low battery, automatic switch off, receiving
unit not powered):
- all outputs in the receiving unit are disabled: if this generates a hazardous situation, the
corresponding commands on the machine must be kept active
- it is not possible to enable or disable the machine commands until the radio remote control
is started up again.
3.1.2 Delay in command response time
Due to the characteristics of radio propagation (i.e.: EM interference, out-of-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.
Those who decide upon the installation of the radio remote control must make sure that this
delay never leads to a dangerous situation in the specific uses.
3.1.3 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. commands requiring two-hand operation, “dead-man” function) if particular environments, equipment and working modes could cause accidental bumps to the actuators.
3.2
Staff training
All installation, usage and maintenance operations must be carried out by qualified technicians who are suitably trained with respect to:
- warnings resulting from risk assessment
- regulations and reference laws
- instructions and warnings provided in the documents related to the industrial radio remote
control and to the radio remote controlled machine

Working conditions
- instructions provided by those who install the radio remote control on the machine and by
the person in charge for workplace safety where the system machine+radio remote control
is used
3.3
Working conditions
To guarantee correct radio remote control operation, all current regulations regarding safety
at work and accident prevention should be respected. All applicable standards and regulations valid in the user country regarding the use of both the machine and the radio remote
control must always be respected.

- make sure that the working and usage conditions are safe
- pull or turn the STOP pushbutton in the arrow direction to unlock it
- start up the radio remote control.
4.2.6 Switching off
The A8 unit automatically switches off in the following cases:
- voluntary switch off when the START pushbutton and immediately afterward the FUNCTION pushbutton are deeply pressed for 3 seconds
- as a response when the STOP pushbutton is pressed
- automatic switch off when there are no enabled commands for a predetermined timeframe.
This timeframe is provided tin the technical data sheet (SWITCH-OFF).
Before the A8 unit switches off automatically, the green and red LEDs blink alternating for
30 seconds.
4.3
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.
Before starting to work, the user shall do the following:
- stand in a position that allows the direct supervision of the remote controlled
machine and its load, and stay in a place ensuring safety conditions in respect of other operations and/or activities and/or processes that are carried
out in the working environment;
- never start up or use the transmitting unit if the working conditions present
the risk of losing balance or tripping;
- always check that the mechanical operation of the STOP pushbutton is correct. If it is impossible or difficult to press this pushbutton, do not use the radio remote control;
- only start up the transmitting unit when starting work: improper use may
cause hazardous situations;
- never start up or use the transmitting unit in closed spaces, with the machine
not in sight, or outside the radio remote control working range: in such cases
it is in fact still possible to build a radio link, thus causing the risk that unwanted commands be carried out by the machine;
AUTEC - AIR series

Warnings for use
- get familiar with the correspondence between the pushbuttons and the machine's movements (this is indicated in the attached technical data sheet) and
learn symbols on the panel of the A8 unit (symbols used are defined by the
machine manufacturer and/or installer depending on the machine's operation
and functions).
During normal operation, the user shall do the following:
- visually and directly follow all movements of the machine and its load and remain inside the radio remote control working range;
- use the transmitting unit in a simple and comfortable way, avoiding accidental falls; the hand strap (wrist band) provided with the radio remote control is
used for that purpose;
- pay particular attention to warnings and visual/acoustic signals, and take all
measurements and steps to avoid that movements of the remote controlled
machine leads to hazardous situations for people and/or property;
- pay attention to the entire work area. Immediately press the STOP pushbutton
when a hazardous situation occurs;
- pay attention to the low battery signals. The A8 unit cannot be used during
the charging process; all dangerous operations (i.e. hanging load) must
therefore be brought to an end before the battery is completely flat;
- in case of malfunction, disable the system “machine+radio remote control”
until the problem has been completely solved.
After using the radio remote control, the user shall do the following:
- switch off the transmitting unit when work is stopped or temporarily interrupted. Do not leave the load hanging (even while recharging the unit);
- never leave the transmitting unit unattended if it is on.

5.4
Warnings for installation
The radio remote control can only be installed and tested by competent staff that masters the
technical knowledge required to carry out such procedure and is qualified according to the
regulation of the country where the radio remote control is installed. Only if the radio remote
control is installed correctly can it be used safely.
Besides instructions established by the machine's manufacturers, installers must always observe the following warnings.
5.4.1 General
Respect and enforce the provisions of all reference standards relevant in the
concerned application field (i.e. EN IEC 60204-32 for hoisting machines).
Always follow the instructions provided in the technical data sheet to carry out
correct installation.
5.4.2 Mounting and fastening the unit in the best position

5.4.3 Positioning the antenna
The antenna is inside the receiving unit. Hence, install the receiving units so
that shields, structures or materials do not obstruct the radio link; in particular:
- the receiving unit shall not be placed inside closed metal containers
- the receiving unit must be placed at least 50 cm far from metal objects in its
surroundings.
If this warning is disregarded, the radio remote control working range may be reduced.
5.4.4 Wiring
The receiving unit's AC power supply must be as follows:
- be protected against short circuit
- have a switch that allows power supply disconnection during installation,
wiring and/or maintenance operations.
Pay special attention to the currents flowing in the SAFETY and STOP outputs:
they shall not exceed the maximum permitted values.
To obtain the UMFS protection, connect the contact of the SAFETY relay in series with the movement commands.

common wire input
movement commands common wire
selection commands common wire
Group the wiring away from the electronic module, in order to avoid interferences and hazards related to electrical safety.
The STOP circuit in the receiving unit has two contacts connected in series
through the bridge between terminal 34 and 35 (producer 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.
5.4.5 At end of installation
Make sure that during installation the safety mechanisms on the radio remote
control and/or in the machine have not been made ineffective by possible procedures carried out.
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 screw in the screws.

5.4.6 Testing
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).
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.
In case of malfunction, disable the system “machine+radio remote control” until the problem has been completely solved.
6 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.
All fine-tuning, checking and maintenance actions carried out on the radio remote control
shall be verified and recorded by the person in charge of carrying out maintenance on the
machine.
In case of malfunction or damaged parts, disable the system “machine+radio
remote control” until the problem has been completely solved.
Before any maintenance operation, disconnect power supply from the receiving unit.
After any maintenance operation:
- always make sure that commands sent by the transmitting unit only activate
the corresponding expected operations
- if the transmitting 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.
6.1
Routine maintenance
Routine maintenance consists of operations needed to preserve the radio remote control normal usage conditions, thus implementing fine-tuning, checks, planned replacement actions
that necessarily arise from the normal use of the product.
All given instructions must be followed correctly at each commissioning, that is:
- whenever the radio remote control and/or the machine is installed or assembled
- whenever the machine location/position changes
- after special maintenance.

Radio remote control maintenance
Routine maintenance
Routine maintenance carried out as described in this manual is fundamental for using the radio remote control safely.
Special applications may need more specific routine maintenance actions to be carried out
at different periods (i.e. if the working environment is particularly dirt, in case of heavy applications or if the system is used very frequently, some maintenance actions may be required
more frequently, depending on the decision of the person in charge for safety in the worksite).
6.1.1 Daily routine maintenance
Before starting to work:
- make sure that the recharging contacts are always clean
- make sure that the pushbuttons' gaskets are intact, soft and elastic
- 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.
During normal operation:
- check structural integrity of the transmitting unit
- make sure that materials that could endanger the transmitting unit usage and safety (such
as concrete, sand, lime, dust) do not deposit on it.
After using the radio remote control:
- clean the transmitting unit: never use solvents or flammable/corrosive materials and do not
use high-pressure water cleaners or steam cleaners
- store the transmitting unit in clean and dry areas.
6.1.2 Three-month routine maintenance
Every three months:
- remove dust or deposit of material from the receiving unit: never use solvents or flammable/corrosive materials to clean it, and do not use high-pressure water cleaners or steam
cleaners
- check structural integrity of the receiving unit
- make sure that the wiring of the receiving unit is intact and connected
- make sure that the receiving unit panel symbols can be easily recognised and replace the
panel if necessary
- check that the plates on the receiving unit are readable and intact.
6.1.3 Six-month routine maintenance
Every six months:
- make sure that all the relay contacts of the receiving unit operate correctly, and check that
the contact closes when the corresponding manoeuvre is enabled and opens when the
manoeuvre is disabled
- check the correct correspondence between the commands that are sent and the manoeuvres that are carried out by the machine

Special maintenance
- check that the contact of the SAFETY relay is open when no movement command has
been sent. This is safety critical maintenance: it is necessary to keep a record (date, signature, comments) showing that this check has been regularly carried out. Keep the record
together with other installation documents.
6.2
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.
Prior to contacting the support service technicians:
- read and understand all documents related to the radio remote control, and make sure that
all the instructions they contain have been accomplished correctly
- follow the instructions to detect possible malfunctions and their origins.
Any fault should be repaired by authorised personnel only (contact the support service of the machine's manufacturer), using original Autec spare parts only.
The following radio remote control data must be reported in order to make interventions faster and more reliable:
- radio remote control serial number (S/N)
- purchase date (given on the certificate of guarantee)
- description of the problem found
- address and telephone number of the place where the device is being used (with the name
of the person to contact)
- local supplier.
6.3
Malfunctions
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.
Look for radio remote control malfunctions as follows.
