Instruction Manual

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.

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. Every time this link is incorrect
or interrupted, the Receiving Unit stops the commands and orders the Machine to stop.
The Machine stops only if the wiring between the Receiving Unit and the
Machine itself is correct.
The two Units in a Radio Remote Control encode their messages through an address that is
unique (produced by Autec only once and non repeatable for other Radio Remote Controls)
andunivocal(speci󰘰c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,
- exceededworkingrange(see"PartB"intheInstructionManual),
- 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.
