3 RADIO REMOTE CONTROL DESCRIPTION
Industrial radio remote controls are used to
command machines from a distance. Each in-
dustrial radio remote control is made up of a
portable transmitting unit, from which the
user can remotely control the machine, and a
receiving unit installed on board the machine
itself. The transmitting unit sends a coded
message over radio frequency transmission.
This message contains a value called “ad-
dress”, which lets the receiving unit decode
only the messages coming from its own
transmitting unit (the one that has the same
address).
This ensures that no interference can activate
any command. If the radio frequency trans-
mission is disturbed, incorrect or interrupted,
the receiving unit autonomously stops the
whole system.
4 WARNINGS REGARDING INSTALLATION
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS MAY RE-
SULT IN SERIOUS INJURY OR DEATH TO PERSONNEL AND DAMAGE
TO EQUIPMENT.
Installation must only be carried out by qualified people and in ac-
cordance with the standards and regulations in the country in which
the system is to be installed. Only a correct installation can ensure
the necessary level of safety during subsequent radio remote con-
trol use.
General
indications
Respect the machine operational characteristics when connecting the Radio remote
control. The safety circuits on the radio remote control and/or present on the
machine should not be bypassed (or excluded).
The receiving unit wiring can be configured very easily, therefore it can be installed
without having to modify the machine. Do not modify the machine electric panel with-
out the machine manufacturer authorization.
Disconnect the receiving unit by detaching all the electrical connec-
tions each time some welding operation is performed on the ma-
chine.
Installation
The receiving unit must be placed in a position that favours reception of the
signals issued by the transmitting unit.
It should therefore be assembled vertically (antenna upwards). The receiving unit
should also be easily accessible to permit operation under safe conditions.
If the receiving unit is covered by metal structures or installed inside metal panels,
use the appropriate extension kit for external antennas.
The antenna must never come into contact with metal parts.
It is forbidden to pierce the receiving unit casing. Doing so compromises the
protection degree against external agents (level IP65).
The vehicle creates vibrations, therefore antivibration blocks must always be used to
reduce the effect that these vibrations have on the receiving unit.
The receiving unit must be positioned away from heat sources (exhaust pipes, alter-
nators, radiators etc.)
Wiring
Most machines are connected to the receiving unit by multiple-pole plugs which per-
mit quick disconnection of the radio remote control for replacement with a hard wired
