2. USE INSTRUCTIONS
2.1 GENERAL INFORMATION
The ELCA Radio System Type MITO is an innovative family of low-power industrial radio remote controls, used to control
appliances that do not require Stop safety function.
The ELCA Radio Remote Control System Type MITO is comprised of two main Units:
- a Transmitting Unit (AT) that sends the command selected by operator in the form of a sequence of digital data;
- a Receiving Unit (AR) that decodes the sequence of digital data for the machine to perform selected command.
The radio control system allows the operator free movement around the machine. The transmitting unit requires no cable
connections and the operator can stand at a safe distance from the machine, in a position affording a better view of
machine movements.
Each Radio remote control uses a unique identifier code set at the factory that cannot be modified. This way, each
transmitting unit can only operate with the associated receiving units and will not conflict with other radio remote controls.
One or more transmitting units can be associated to a given receiving unit through the identifier code learn procedure.
Working frequency is automatically selected when the transmitter is activated from available low-noise frequencies. In
service, any persistent radio noise will automatically trigger a frequency change without interrupting operation.
The special LbT (Listen before Transmit) Full Duplex technology used by the MITO system allows the selection of low-
noise frequencies, and also provides a 2-way communication link between transmitter and receiver, i.e. is capable of
handling feedback information from the receiver. Such two-way communication ensures full control of the machine, as
the receiver sends back an “acknowledge” signal after receiving each command to confirm that the command has been
carried out. If the transmitter receives no “acknowledge” signal, it stops transmission alerting operator to the fact the safe
transmission is not ensured.
The sophisticated signal coding / decoding protocol used by the system ensures high reliability of transmission data with
a Hamming distance of 10 and above.
Product not suitable for use on machines for lifting things, people and all those applications which require a STOP
command with safety function.
2.2 APPLICATIONS AND USE CONDITIONS NOT PERMITTED
The Radio Remote Control MITO, should NOT be used:
- for the control of devices in which both require the presence of a Stop safety command;
- for the control of devices for lifting persons;
- on machines that require the capability to operate in explosive atmosphere (ATEX);
- on equipment where the stop of the remote control is not sufficient to put in safety conditions the
driven machine, which can then be a possible cause of danger;
- on machines where risk analysis is not possible or has given negative results;
