7. RADIO REMOTE CONTROL OPTIONS
These options may not be present in your radio remote control. Consult technical attachments and
read the paragraphs for the options included with the radio remote control
7.1. MTRS and MTRS Easy Option
The transmitter-receiver multi system enables each receiver to be able to recognise a maximum of 8
transmitters with which it can operate one at a time, and every transmitter to be able to operate with a
maximum of 16 receivers at the same time.
The MtrS and MtrS Easy option is available on the full range of transmitters and receivers apart from 4
transmitters recognisable on L and M receivers, whereas with the H series it can reach up to 8
transmitters. The MtrS and MtrS Easy are differentiated by the Lock and Unlock procedure described
subsequently.
The MtrS or MtrS Easy option is indicated for all those application sectors which require for multiple
operators to safely operate on the machines:
• Automatic warehouses
• Funicular cranes
• Overhead travelling crane
7.1.1. Transmitter
7.1.1.1. Definition of combination
The combination indicates which receivers have to work at the same time
during the working session.
The combinations are personalised depending on the clients needs and are
programmed by IMET during the radio remote control manufacture.
Each transmitter can handle up to 16 different receiver combinations with which it can operate at the
same time.
The combinations may vary from one transmitter to another. The MtrS option enables to realise
different functioning, typical of lifting machines:
• TANDEM
• MASTER-SLAVE
• CATCH-PITCH (TAKE-RELEASE)
7.1.1.2. Selecting the desired combination
Attention: if a toggle switch is not present, pass on to the next paragraph.
The desired receiver combination is selected using a rotating selector. Makes it possible to select the
receivers and therefore the machines on intends to operate with. Once the desired work combination
has been set, one must proceed with taking control of the receivers in order to guarantee that they are
exclusively used by the transmitter.
7.1.1.3. Lock procedure
This procedure allows taking control of the receivers to guarantee the exclusive use on behalf of the
transmitter.
Before proceeding, ensure that all receivers are free, meaning they are not already being exclusively
used by other transmitters (see page 12).
