1.2 Applications
In compliance with the risk assessment (see chapter 2), this radio remote control
can be installed on hoisting and material handling machines and on machines for
moving, raising and transporting people (i.e. hydraulic cranes, aerial work plat-
forms, telehandlers, concrete pumps).
This radio remote control cannot be installed:
- on machines installed in places where equipment with explosion-proof
characteristics is required
- on machines where the receiving unit power supply does not come from
a battery or from a power supply unit with safety isolating transformer
- to control loads that are not isolated from AC power supply (if that is the
case)
- on machines that may generate dangerous situations if they stop due to
the loss of radio link
- on machines for which a risk assessment (see chapter 2) is not possible
or gave negative results.
Autec cannot be held responsible if the radio remote control is installed on forbid-
den applications.
1.3 Radio link
The two units constantly communicate with one another through a radio link. This
is an essential requirement to ensure safety for the radio remote controlled ma-
chine.
Messages from the units are coded through an address stored in the S-KEY (see
paragraph 6.2). This address is unique (Autec produces it only once), univocal
(specific 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.
The units send coded messages to one another:
- messages sent by the transmitting unit contain operational commands to be
carried out by the machine
- messages sent by the receiving unit contain information useful for the auto-
matic management of the working frequency and information about measure-
ments collected from the machine (Data Feedback function).
