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 documentation adds to and completes the information provided
by the manufacturer of the remote controlled 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.
Three symbols are employed throughout documentation, which are used to highlight specic
safety-related issues. They are classied according to the hazardous situation that may arise
and on the possible consequences:
If the highlighted instructions are not respected ...
Symbol
... a dangerous situation
will occur…
…highly probable.
...consequences for
people may be…
… critical (death or
physical damage).
...consequences for
property may be…
… critical.
… probable.
… probable.
… critical (death or
physical damage).
… moderate (non-severe
physical damage).
… critical.
… moderate.
This symbol is also used, and it identies texts to be read carefully.

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 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 installed in places where equipment with explosion-proof characteristics
is required
- 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.
1.3 Technical Data
Command response time (typical) ........................................................................... 100ms
(Typical) working range ..................................................................... 75-100m (240-330ft)
Stop time (typical) ................................................................................................... 100ms
Max. stop time ............................................................................................................. 0.5s
Performance Level of safety functions according to ISO 13849-1:
Stop protection ........................................................................................................... PL d
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.
This address is unique (Autec produces it only once), univocal (specic for each radio remote
control) and not reproducible. Each unit can only decode the messages coming from the unit
with the same address.
This prevents messages from other radio equipment from activating any system function.

1.5 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).
1.6 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 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.
1.7 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.).
The SERIAL N. 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.
These plates must not be:
- removed from their position (removal will invalidate the guarantee)
- altered or damaged (contact Autec for replacement)

Risk assessment
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.
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.
If required by the risk assessment, draw up protection measures to prevent, reduce and
report potential hazard 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 1.2)
- 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
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 until the radio remote
control is started up again.
