1 Description of the AIR series' radio remote controls
1.1 How the radio remote control works
Industrial radio remote controls are used to control machines from a distance, without phys-
ical 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.
The two units constantly communicate with one another through a radio link. They automat-
ically search for a free working frequency.
The two units use messages coded through an address that is unique (produced by Autec
only once) and univocal (specific for each radio remote control).
1.2 Applications
AIR series' radio remote controls can be installed on hoisting and material handling machines
(i.e. overhead cranes).
As required by standards ISO 12100 and ISO 14212, risk assessment must be carried out
for each machine (see chapter 3). The radio remote control can only be used if this assess-
ment gives positive results. However, this radio remote control cannot be installed:
- on machines installed in places where equipment with explosion-proof characteristics is re-
quired
- on machines for moving, raising and transporting people.
- on machines that may generate dangerous situations if they stop due to the loss of radio
link
