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
codified 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".
The radio link is sensitive to particular conditions in the
environment, like for example the presence of metal obstacles
or electromagnetic interference.
If the connection between the Transmitting Unit and the Receiving
Unit is interrupted or is incorrect, the system provides that the
Receiving Unit commands the Machine to stop.
There are various reasons for an interruption of the connection:
• programmed automatic shut-off;
• Transmitting Unit low battery;
• no power supply to the Transmitting Unit;
• STOP button pressed;
• automatic connection interruption;
• operating range exceeded;
• presence of metal obstacles.
For the Machine to stop, however, the wiring between the units
must have been made correctly.
When the radio link is interrupted all the outputs of the Receiving
Unit are disabled. To be able to activate/deactivate the controls of
the Machine using the Transmitting Unit the Radio Remote Control
must be switched on again.
8.2.4 Stop
The shut-down is a safety function that puts the Machine in a safe
state each time it is necessary to stop it because of a potentially
dangerous situation.
The stop function can activate:
• by the operator pressing the red STOP button on the Transmitting
Unit (manual mode).
• automatically by the Receiving Unit if the radio link between the
Units is incorrect or interrupted (automatic mode).
THE USER MUST ALWAYS PAY THE UTMOST ATTENTION TO THE
SAFE AND CORRECT WORKING OF THE MACHINE IN
ACCORDANCE WITH THE INSTRUCTIONS AND WARNINGS
PROVIDED IN THIS MANUAL, THE INSTRUCTIONS AND
WARNINGS IN THE MANUAL OF THE MACHINE AND IN
COMPLIANCE WITH ALL APPLICABLE LAWS, REGULATIONS
AND STANDARDS, ALSO LOCAL.
THE ACTIVATION OF THE STOP BUTTON OR THE RETURN OF
THE ACTUATORS TO THE REST POSITION MIGHT NOT CAUSE
THE MACHINE TO STOP IMMEDIATELY.
THE STOP BUTTON MIGHT NOT ACTIVATE A BRAKE.
MOREOVER, DIFFERENT MACHINES HAVE DIFFERENT
RESPONSE TIMES AND STOPPING DISTANCES. EVEN IF THE
STOP FUNCTION IS USEFUL, THE USER SHOULD BE FULLY
AWARE OF THE MOVEMENTS AND WORKING AREAS OF THE
MACHINE AND SHOULD PROVIDE FOR THE SAFE OPERATION
OF THE MACHINE, TAKING INTO CONSIDERATION THESE
RESPONSE TIMES AND STOPPING DISTANCES.
FAILURE TO COMPLY WITH THESE INSTRUCTIONS, EVEN
TEMPORARILY, CAN CAUSE SERIOUS INJURIES OR DEATH OR
DAMAGE TO PROPERTY.
The stop function using the Radio Remote Control is only
available if the Radio Remote Control has been started.
Never leave the Transmitting Unit unattended so that there is
no doubt about the availability of the stop function.
The "useful life", as defined in international standards and
requirements, of the stop function is 20 years. in any case, the
Radio Remote Control should be replaced before then. The
"useful life" cannot be understood as a warranty period.
After the STOP button is activated in the Transmitting Unit, the
Machine is no longer controlled by the Radio Remote Control.
The possible risks deriving from the activation of the stop
function should be evaluated both by the Installer of the Radio
Remote Control as well as by the Manufacturer and the Owner
of the Machine on which the Radio Remote Control is installed.
The User of the Radio Remote Control should be adequately
trained in this regard.

The technical data of the Transmitting Unit in the E2 range are
reported in Part 1 e and in the relative Position of Controls and
Connection Diagram.
8.4 Identification of the Radio Remote Control
The serial number (Serial Num.) uniquely identifies the Radio
Remote Control.
The serial number can be found on the data plate of the Radio
Remote Control; each unit of the Radio Remote Control has its own
data plate.
When sending a request regarding an Elca Radio Remote Control
the serial number (Serial Num.) of the Radio Remote Control itself
must be provided.
The Serial Num. should be reported in all communications with Elca
or with Persons who require information, spare parts or technical
data regarding the Radio Remote Control.
Do not remove the data plate on the Units from their position,
since removing it will immediately void the warranty.
If the data plate has been altered or damaged, contact Elca for
a replacement.
8.5 Transportation and/or storage
The Radio Remote Control and all its parts should be transported
and
stored
according
to
environmental conditions:
Operation
Transportation
Storage
The original packaging should be kept for the entire life of the
product.
Use the original packaging for transporting and storing the Radio
Remote Control in all the phases of its life, for example before
installing and after its removal.
