8 Radio Remote Control of the Range E1
8.1 Characteristics
An Elca Radio Remote Control of the E1 series belongs to a family of
industrial Radio Remote Controls, that can mainly be used, but not
only, for controlling lifting and transportation apparatus.
With a Radio Remote Control it is possible to control the Machine
from a remote position and without a physical connection using wi
or connection cables.
The User manages the machine from a distance using a Transmitting
Unit (portable) that dialogues with a Receiving Unit (xed) installed
on the Machine itself.
This chapter contains images of the individual units that make up the
Radio Remote Control, please look at the parts concerning each Unit.
8.2 Frequencies and radio link
8.2.1 Frequencies
The radio link between the Elca Radio Remote Control units in the
E1 range occurs at one of the frequencies permitted under European
regulations in force at the time when placed on the market.
The E1 range operates using the 434,050-434,790MHz frequency band.
Depending on the specic market there are laws and regulations
that establish the frequency with which a Radio Remote Control
can operate.
If these laws and standards are not respected, the Radio
Remote Control cannot and should not be used.
It is not the responsibility of Elca to check whether the Radio
Remote Control is congured during installation and used with
a frequency other than that permitted in the country where
it is to be used.
The Radio Remote Control is made in such a way that when started it
looks for a free frequency to use. The automatic search for a frequency
allows a free frequency to be found free from interference. It also allows
other apparatus in the vicinity not to be disturbed and vice-versa not
to be disturbed by them.

8.2.3 Description of the radio link
The Transmitting Unit communicates with the Receiving Unit using a
radio link.
The system uses electromagnetic waves to transport the control signals.
The Transmitting Unit and the Receiving Unit communicate through
codied messages that contain a unique code.
Each unit can decode only the messages coming from the Unit that
possess the same code. This is to exclude the possibility that another
radio apparatus could send commands to the Machine on which the
Radio Remote Control is installed.
Each Radio Remote Control operates within and not beyond a certain
distance, beyond which the communication between the Units is lost.
This distance is called “operating range”.
