7.2. Connecting the receiver
Do not perform any operation until the equipment is powered off.
The power supply for the radio remote control should be located downstream from the machine’s main
switch.
Connecting it directly to the mains distribution network is prohibited. The mains disconnecting
switch must be equipped with a device to prevent unauthorized closing (padlock). It must be
easily accessible and be attached outside of the equipment. The distance between contacts
must be of at least
3 mm.
The connection between the receiving unit and the machine should always be REMOVABLE. If the
connection is made directly on the terminal board inside the machine, a multipolar connector should
be used, so that the receiver can be disconnected and the original wired controls restored at any time.
Conductors and cables shall be selected so as to be suitable for the existing operating conditions (for
example, voltage, current, protection against electric shock, grouping of cables), as well as external
influences (for example, ambient temperature, presence of water or corrosive substances, mechanical
stresses-including stresses during installation- and fire hazards). When cables are installed on hoisting
machines used in the open air (outside buildings or other protective structures), they shall be suitable
for outdoor use (for example, UV-resistant, adequate temperature range), or be appropriately
protected.
The wire connections between the receiving unit and the machine should respect the Standard
EN60204 and must be stranded. The wires must have a cross-section of at least 0.75 mm2 and less
than 13 mm2 and be self-extinguishing. If the equipment is used with ambient temperature of 70°C the
maximum conductor operating temperature must be greater than 75°C.
Use ferrules for conductor ends, if possible, and make sure that the terminals are fastened tightly.
Consult the transmitting unit control diagram (Annex T) and the receiving unit wiring diagram (Annex
R) to identify the equivalent actuators in both units.
In the HDC version, the receiver is also intended to be electrically powered at a voltage of 24 VAC
50/60 Hz. Connect it to an external source where the dedicated 24 VAC output is separated from
dangerous voltage parts by double or reinforced insulation.
In all receiver versions, the loads connected to the relay board must have a protection against over
currents and overloads.
In the HDC version, the receiver is intended to be electrically powered in the voltage range 11 to 30
Vdc. Connect it to an external source where the dedicated 11-30 Vdc output is protected against
overvoltage and short circuit. The 11-30 Vdc dedicated output external source must be connected to
the main terminal earth protection or separated from the primary circuit by means of a metal screen
connected to the main terminal of the earth protection.
When the receiver type HDC is provided with a metallic connector (mounted on the enclosure), the
device shall be placed in a "service access area" not accessible to the operator, but only by the
service staff
(EN 60950-1 4.5.4 Touch temperature limits of metals at 70°C)
Be sure to note the supply voltage when connecting the receiving unit
.
In versions HAC and LAC, the fuse current must be adjusted to the supply voltage.
After installing, test the radio remote control and the machine to make sure they work as
expected. In addition, it is very important to make sure that the STOP circuit works properly.
Pressing the STOP button during normal operation should open the contacts of relays A and B
in the E-STOP circuit.
Lastly, fill-out the sheet showing the connection diagram between the receiving unit and the machine
and write down the date of installation in the document DECLARATION OF CONFORMITY.
