9.1 Warnings for the Installer
In addition to all information made available by the Machine
Manufacturer, the Installer should always take the following
precautions:
• understand and comply with all the technical and warning
provided by the Manufacturer of the Machine;
• carry out a thorough risk assessment considering the use of the
Machine with the aid of the Radio Remote Control.
• implement and comply with the provisions of the reference
standards for the field of application of the Machine on which
installation is being carried out;
• understand and comply with all the applicable Laws, Regulations
and Standards, also local;
• comply with all the warnings and instructions given by the person
in charge of starting up the Machine and preparing it for work;
• comply with all the indications and warnings contained in the
Manual of the Radio Remote Control;
• use the Elca Radio Remote Control only as indicated in this
Manual and in all the instructions provided by Elca;
• use the Machine on which the Elca Radio Remote Control is
installed only in safe conditions and only if it is possible to get a
good view of the working area of the Machine;
• check that there are no hazardous conditions in the event the
Radio Remote Control stops due to the loss of the radio link;
• prevent the use of the machine when there are problems, faults,
wear or breakages;
• immediately inform your superiors and/or workplace and/or
Machine managers of any faults that could cause the Radio
Remote Control and/or the Machine to malfunction or that could
be a cause of injury to Persons and damage to property;
• keep the Transmitting Unit safe so that it cannot be used by
unauthorised or unqualified personnel;
COMPLY WITH THE ADDITIONAL WARNINGS AND
INSTRUCTIONS THAT ARE CONTAINED IN OTHER PARTS OF
THIS MANUAL.
9.2 Positions and mounting of the Receiving Unit
Position the Receiving Unit so that it is easily accessible. Position
the Receiving Unit so that it is as far away as possible from metal
parts (at least 50 cm) and never inside metallic or conductive
materials.
Position the Receiving Unit vertically, with the cable gland or plug
facing down.
Fix the Receiving Unit in four points using the holes on the housing.
Never put a hole in the Receiving Unit.
When installing on Machines that are subject to heavy stresses (for
example: vibrations, rocky terrain, sudden movements), we
recommend fixing the Receiving Unit to the Machine with vibration
dampers.
9.3 Receiving Unit wiring
By wiring is meant the electric connections using cables and that
are made inside the Receiving Unit or between the Machine and the
Receiving Unit.
In the wiring phase it is necessary to:
• avoid exposing the Receiving Unit to strong vibrations, if
necessary using appropriate vibration dampers;
• connect the Receiving Unit to the machine using multi-pole
connectors so that it can be easily disconnected if it needs to be
sent to a service centre;
• for the wiring, use cables of a suitable diameter max. 2.5 mm²
terminated with wire clips or terminals;
• the power supply of the Receiving Unit must be protected
against short circuits;
• always make sure that the value of the supply voltage complies
with the rated voltage indicated on the data plate of the Receiving
Unit.
• provide for the possible disconnection of the power supply to the
Receiving Unit during installation, wiring and maintenance
operations;
• avoid using the connector for the multi-feed power supply of the
Receiving Unit (0, 48, 55, 110, 230 Vac) to distribute power to the
rest of the control relays;
• pay attention to the current in the STOP and SAFETY relays so
that it never exceeds the permitted value (see paragraph 11.1 );
• you MUST always use the STOP contact on the Receiving Unit;
• join the wires together by means of binding, making sure that the
wires are far away from the electronic module and are sufficiently
fastened so they remain stationary even if released from the
connector, and avoid potential hazards related to electrical
safety.
When the installation is finished, it is necessary to:
• test the machine operated by the Radio Remote Control,
checking the actual safety of the machine by means of the STOP
command, the exact correspondence of the command symbols
with the actual movement of the machine;
• check that during the installation operations were not carried
out that render the Machine's safety systems ineffective (limit
switches, interlocks, load limiters, etc.).
• check that the contact of the SAFETY command is in series with
all commands to which protection is required;
• check also that the Machine operates correctly the without the
use of the Radio Remote Control where possible;
• if abnormal operations are experienced, DISABLE the Machine
until the problem s completely resolved;
• close the Receiving Unit checking firstly whether the gasket in
the cover is undamaged.
9.4 Positioning the antenna
Install the Receiving Unit in a vertical position, in a free area of the
Machine that can easily be accessed, where there are no guards,
panels, parts, surfaces or the like so that shields, structures or
materials do not obstruct the radio link. In particular the Receiving
Unit should be positioned not less than 50 cm from surrounding
metal objects and should never be located inside closed metal
containers.
