4 Radio Remote Control features
Air series' Radio Remote Controls are used to control Machines from a distance, without
physical connection (by way of example: wires or connecting cables) between the Transmitting
Unit handled by the User and the Receiving Unit installed on the Machine, hence between
the User and the Machine.
They consist of a portable Transmitting Unit, from which the User can remotely control a
Machine, and a Receiving Unit installed on board the Machine itself.
Images of the single Units belonging to the Radio Remote Control can be found in the specic
manual that refers to each Unit.
4.1 Description of radio link
The Transmitting Unit communicates with the Receiving Unit through a radio link. Such
link must be continuous to promote safety in the use of the Machine. Each time this link is
incorrect or interrupted, the Receiving Unit stops the Radio Remote Control command and
instructs the Machine to stop: the Machine stops only if the wiring between the Receiving
Unit and the Machine itself is made in a correct manner.
The two Units in a Radio Remote Control code their messages through an address that is
unique (produced by Autec only once and non repeatable for other Radio Remote Controls)
and univocal (specic for each Radio Remote Control and associated to it).
Each Unit can only decode messages coming from the Unit with the same address.
This prevents messages from other radio equipment from activating any "Machine+Radio
Remote Control" system function.
The radio link is interrupted in the following cases:
- stop (see paragraph 4.2.2),
- low battery,
- automatic switch o,
- no power supply in the Receiving Unit,
- out of working range condition (see paragraph 4.3),
- presence of metal obstructions.
WARNING: The maximum working range may vary significantly and
unpredictably when special conditions occur in the working environment
(by way of example: temporary presence of electromagnetic interference
and/or metal obstructions).
When a radio link is interrupted:
- all outputs in the Receiving Unit are disabled,
- it is not possible to enable or disable the Machine commands through the Transmitting
Unit until the Radio Remote Control is started up again.
