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 1.3)
- 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 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, out-
of-working-range condition), a delay up to the "Passive 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.
