14.2.3 Quarterly routine maintenance
At least every three months:
• check that the commands sent and movements carried out by
the Machine correspond;
• check that when no movement command is sent the contact of
the SAFETY relay is open. After carrying out the maintenance the
work must be recorded (date, signature, comments) as evidence
that the control was duly carried out. Keep the record together
with the other installation documents, since it is an important
maintenance intervention concerning safety.
14.3 Special maintenance
By special maintenance is meant the operation and the entirety of
repair operations that have to be carried out following breakages,
faults or malfunctions of the Radio Remote Control.
Special maintenance beings the Radio Remote Control back to its
original conditions of use and operation.
Special maintenance should only be carried out by a qualified
Elca person.
The qualified Elca person is a specialised technician who has
the specific skills and competences with regard to the Radio
Remote Control.
No specialised technician can carry out special maintenance
operations on the Radio Remote Control if he does not belong
to the Elca assistance network or who is not expressly
authorised by Elca.
For the special maintenance operations only original Elca parts
and materials should be used.
The instructions and maintenance Manual should be available
for the specialised technician entrusted with the special
maintenance operations.
When requesting assistance and/or spare parts from Elca, you
must provide the serial number of the Radio Remote Control, the
date of purchase, and the problem encountered.
To enable the request to be met it is also helpful to know the address
of the place where the Radio Remote Control is used, the name and
telephone number of the person to contact, as well as the company
supplying the Radio Remote Control.
15 Guide to solving problems
If the Radio Remote Control is not working correctly, carry out the
following preliminary controls:
• move all the Transmitting Units in the work area away from the
Elca Transmitting Unit used, in order to avoid possible radio
disturbance and interference;
• move the Elca Transmitting Unit closer to the corresponding Elca
Receiving Unit, in order to avoid possible radio disturbance and
interference, positioning it always in a safe place with a complete
view of the Machine, the work area and the load, if present;
• check to see if the problem is with the Radio Remote Control or
the Machine: to this end, it is necessary to do a control test of the
Machine using a different control station to the Radio Remote
Control, if present. If the problem persists after this test, you
need to work on the Machine following the Manufacturer's
instructions. Otherwise the problem is with the Elca Radio Remote
Control, so further controls will be needed.

16 Decommissioning and disposal
16.1 Decommissioning
After its decommissioning the Radio Remote Control should be
transported and kept in accordance to what is in paragraph 8.5 .
16.2 Disposal
If disposing of all the parts of the Transmitting Unit and its charging
system, they all should be treated as separated waste. Disposal
should comply with the legal provisions and regulations in force in
the country of use.
SUGGESTED REMEDY
Supply power to the
Receiving Unit.
Check for voltage on
the power supply
terminals. Check that
the power cable is
connected correctly.
Ensure there are no
other similar systems
or sources of
interference such as
radio relay systems or
transmitters. Switch
off the Transmitting
Unit and then switch
it back on.
Check that the
Transmitting Unit is
active and correctly
connected. Make sure
that the operating
distance is within the
work range and that
