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. Always remember that:
- photos and drawings are useful examples that help understand the instructions and
warnings of each radio remote control conguration
- if necessary, contact Autec if any of the instructions and/or warnings are not clear.
No part of the documentation may be reproduced, in any form or by any means, without
written permission of Autec (including recording and photocopying).
If documentation is lost or damaged, ask Autec for a copy. Please specify the serial number
of the related radio remote control.
The documentation must be kept for the whole life of the radio remote control: after reading
it, keep it on hand for future reference.
All installation, usage and maintenance operations must be carried out by qualied technicians
who are suitably trained with respect to the relevant norms and laws.
Information contained in the radio remote control documentation adds to and completes the
information provided by the manufacturer of the remote controlled machine and/or by those
who install the radio remote control on the machine.
Therefore, this documentation must be read and understood in all its parts by the user and by:
- the radio remote control owner and/or installer
- the person responsible for and in charge of maintenance and/or safety in the workplace
where the radio remote control is used.
As for instructions and warnings regarding the machine where the radio remote control is
installed, follow the instructions given in the machine's manual.

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.

Working range (typical) ..................................................................... 75-100m (240-330ft)

Max. stop time ............................................................................................................. 0.5s

1.3 Applications
AIR series' radio remote controls can be installed on hoisting and material handling machines
(i.e. overhead cranes).
AIR series radio remote controls cannot be installed:
- on machines working in zones with risk of explosion
- on machines for people lifting and transportation (the machine's
manufacturer may authorize installation and use of a radio remote
control on such applications under their own responsibility, if the risk
assessment they carried out gave positive results)
- on machines that may generate dangerous situations if they stop due
to the loss of radio link
- on machines for which a risk assessment is not possible or gave negative
results
Autec cannot be held responsible if the radio remote control is installed on forbidden
applications.

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 (specic for each radio remote control). Each unit can only decode
messages coming from the unit with the same address.
This prevents messages from other radio equipment from activating any "machine+radio
remote control" system function.
1.5 Classicationofcommands
Commands sent by the transmitting unit are classied according to their type.
1.5.1 Type of command: analogue or digital
Commands sent by the transmitting unit can either be analogue or digital.
Analogue commands generate proportional outputs as a function of the position of the
corresponding actuator.
Digital commands switch the status of their corresponding output, according to the position
of the related actuator. This status can either be on or o.
1.5.2 Name of commands
All commands sent by the transmitting unit are identied by abbreviations, which are written in
the technical data sheet to highlight the match between commands sent and machine functions.
1.6 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).
The stop function by means of radio remote control is available only if the radio remote
control is started up (see "Starting up the radio remote control" in the "Part C" of the manual).
In any other condition the transmitting unit is not able to bring the machine in a safe state.
Never leave the transmitting unit unguarded in order to avoid uncertainty
about the availability or unavailability of the stop function.
The life time of the stop function is 20 years. In any case, the radio remote
control must be replaced within this period.

Radio remote control description
1.7 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. Each time one of those actuators is operated, the transmitting unit sends both
the movement command and the “SAFETY” command.
1.8 Identifying the radio remote control
As required by standard IEC 60204-32, each radio remote control is uniquely identied through
a serial number (SERIAL N. or S/N).
The serial number is provided in the identication 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.
Plates on the units must not be:
- removed from their position (removal voids the guarantee)
- altered or damaged (contact Autec for replacement)

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.
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.
If required by the risk assessment, implement protection measures to prevent, reduce and
report potential hazardous situations.
2.1 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 1.3)
- 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
2.1.1 Aspects related to radio link
Whenever the radio link is interrupted (i.e. stop, low battery, automatic switch o, receiving
unit not powered):
- all outputs of the receiving unit are disabled
- it is not possible to enable or disable the machine commands through the transmitting
unit until the radio remote control is started up again.
2.1.2 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.
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 specic uses.
