In carrying out the risk analysis to establish whether the Radio
Remote Control can be installed on a Machine, the Manufacturer of
the Machine and/or the Installer of the Radio Remote Control must
respect all Laws, Regulations and Standards, also local, regarding
the assessment of the risks and the safety of the Machine and the
following recommendations:
• some Machines cannot be fitted with a Radio Remote Control, as
established in paragraph 8.6 ). Also all the other circumstances
that might limit, impede or impose conditions for the use of a
Radio Remote Control on the Machine, or which could effect it
being used correctly and safely should be evaluated.
• The radio link between the two Units can be interrupted (see
paragraph 8.2.3 ).
• all the information regarding the installation, use and
maintenance supplied by Elca should be taken into consideration
(see paragraph 8.6 , paragraph 10 and paragraph 14 ).
• there is a delay between the release of a command in the
Transmitting Unit and the deactivation of the relative output in the
Receiving Unit (see paragraph 7.3 ).
• there is a delay between the activation of a command in the
Transmitting Unit and the activation of the relative output in the
Receiving Unit (see paragraph 7.3 ).
• additional measures might be needed to protect the actuators
(see paragraph 7.4 ).
• it is possible that a command is activated or deactivated
because of electrical and/or mechanical faults.
7.3 Delay in the command response time
In normal conditions, the delay between the activation of a
command in the Transmitting Unit and the activation of the
relative output in the Receiving Unit requires a time equal to the
"Command response time" (typical)" indicated in the Technical
Data (see paragraph 8.3 ). In situations where there is a poor
quality radio link (for example: interference, range of action
reached) this delay can extend up to the "Maximum stop time"
indicated in the Technical Data (see paragraph 8.3 ).
It should be remembered that due to the characteristics of the
radio medium (for example: interference, range of action
reached), the delay between the release of a command in the
Transmitting Unit and the deactivation of the relative output in
the Receiving Unit can extend up to the "Maximum stop time"
indicated in the Technical Data (see paragraph 8.3 ).
The Manufacturer of the Machine, the Installer, the Owner, the
User and the Maintenance Technician need to make sure that
these delays can never lead to a situation of danger in the
specific application.
7.4 Unintended activations of the commands
The User should operate the Radio Remote Control correctly,
following the use and maintenance instructions.
If the Unit is used correctly, accidental contact with parts of
the body of the User or with foreign objects, does not cause the
unintended operation of the actuators.
Any action is carried out on the Transmitting Unit, or part of it,
in order to operate the actuators in a way other than that
indicated in the Manual is an incorrect use of the Radio Remote
Control and cause serious damage to Persons and/or property.
The User should use the Radio Remote Control in compliance
with the use and maintenance instructions and all applicable
Laws, Regulations and Standards, also local, in the country
where the Radio Remote Control and the Machine are used,
always maintaining control of the Radio Remote Control and
the position of use just as described in the specific part of the
Transmitting Unit.

The Manufacturer of Machine and/or the Installer should
assess and eventually adopt additional protective measures for
the actuators (for example: two-hand controls, "dead-man"
function) in the case where particular locations, equipment and
working modes can create situations of risk and in the case this
is required by the applicable Laws, Regulations and Standards
in the country where the Radio Remote Control and the
Machine are used.
It is possible that a command is activated or deactivated
because of electrical and/or mechanical faults, which can
affect the Radio Remote Control and/or the Machine.
The Manufacturer of the Machine and/or the Installer of the
Radio Remote Control should carefully assess what the
consequences of this malfunction are. If the risk analysis
requires it, protective measures should be prepared that avert,
reduce or signal situations of potential risk.
If a command is activated and/or deactivated because of
electrical and/or mechanical faults:
• press the STOP button to put the machine in a safe state,
• disable the Radio Remote Control and cease using the
"Machine+Radio Remote Control" system until the problem is
solved by means of the required technical intervention.
8 Radio Remote Control of the Range
8.1 Characteristics
An Elca Radio Remote Control of the E2 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 wifi
or connection cables.
The User manages the machine from a distance using a Transmitting
Unit (portable) that dialogues with a Receiving Unit (fixed) 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 units of Elca E2 series radio remote
controls uses one of the frequencies permitted by the US and
Canadian standards in force when the system is put on the market.
The E2 range operates using the 915.00 - 928.00 MHz frequency
band.
Depending on the specific 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 configured 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.
