Risk analysis
All warnings listed in this manual have to be taken into account during risk anal-
ysis and when setting out protection measures.
All machines must undergo a risk analysis: it is therefore necessary to evaluate, within the limits
of this analysis, if the machine can be radio remote controlled.
Some warnings and information for risk analysis for one or more machines controlled by a “Mas-
ter/Slave” or “Master/Master” system are provided in this paragraph.
Following information is NOT exhaustive and/or DOES NOT replace requirements of current reg-
ulations in this field.
Risk analysis must always be carried out bearing in mind that the radio remote
control system consists of one or more transmitting units and of more receiving
units.
The machine producer and/or the person who decides upon radio remote control
use and installation is responsible for this analysis.
Autec cannot be held responsible if the risk analysis is not carried out correctly.
When carrying out risk analysis for the machine, the following aspects regarding the radio re-
mote control have to be considered:
1.working application
2.loss of radio link
3.the unintended activation or loss of a command
Working
application
Following has to be taken into account:
- wiring must guarantee correct operation according to whether the receiving unit is installed
on a single machine or on different machines;
- if paired controls amongst the different machines are needed, the radio remote control cannot
guarantee synchronism between the different receiving units;
- if the remote controlled machines are not within the same visual field, the operator should
always be able to know which machines are being activated in a particular moment (i.e.
through an acoustic or light signal).
Loss of radio link
It must be taken into account the fact that radio link with one or more receiving units can be
lost due to radio interferences, power supply disconnection and electrical failures
Carefully evaluate which consequences such malfunction can have.
Activation and
loss of a
command
It must be taken into account that unintentional activation of a command and/or loss of com-
mand selection can be possible. Such unusual situations can be caused by electromechanical or
mechanical failure of the system “radio remote control”.
Carefully evaluate which consequences such malfunction can have.
If required by the risk analysis, draw up protection measures to prevent, reduce
and report potential hazard situations.

Documentation
Instructions
for the
management of
documentation
Documentation enclosed with each radio remote control includes at least the following:
- instruction and warnings manual
- battery charger manual
- technical data sheet.
Make sure that such documents have been supplied: if they are not, please ask them
to Autec specifying the product serial number.
Technical data
sheet
The technical data sheet shows the wiring diagram between the receiving unit and the machine.
The technical data sheet must be filled in and checked by the installer, who is responsible for a
correct wiring. Once all necessary checks have been carried out, the installer must undersign
the technical data sheet, which must be kept with the user's manual (always keep a copy of this
data sheet for administrative purposes).
