5.1 OPERATION DESCRIPTION
The receiving apparatus decodes the digital data sequence and transforms it into electric impulses, which are
necessary for the machine to carry out the selected command.
When the receiving apparatus is being correctly powered, the internal Power LED lights up. The RF Signal LED
indicates the presence of a radio link and the RC connection LED signals that the Radio remote control is
operating correctly. The power input is protected by a fuse.
A machine emergency circuit, which works on the power teleswitch by disconnecting the power supply from all the
relays, can be connected to receivers powered by direct current.
The receiving unit is made up of two essential parts:
1. Receiving and decoding unit: This unit is made up of two functional blocks: the radio block which selects the
signals coming from the antenna and extracts a useful signal, and the decoding block, which analyses the
signal extracted from the radio block, controlling that the decoded data does not contain errors and that the
telegram address corresponds to the one on the connection key. The decoding block also checks itself to
ensure that there are no internal faults, ensures that the supply voltage value is correct and handles system
functionality in general. If everything is normal, the safety circuit (STOP) with relays (2 STOP relays each
guided contact) activates and the relays that correspond to the transmitted commands also activate. The safety
circuit is constantly held under control and when an irregularity arises the whole system is stopped. The system
is also stopped when the decoding unit is not able to extract exact data within a certain period of time (Passive
Stop Time). The manufacturer guarantees connection key individuality, therefore each receiver can only work
with its associated transmitter.
2. Command actuators. These relays activate the machine functions. The normally closed or open contacts are
given on the main card. The supply inputs are protected against over-voltages, as are the normally open
contacts of the relays.
All the outputs of receivers powered by alternate current are available as a pure contact, and the NO contact is
protected from over-voltages. The STOP contact can be used to serial connect a machine emergency circuit, run a
power teleswitch or disconnect the relay commons when the system is not operating. The Start and Alarm relays
are activated by the Start command. The Enable relay remains active while the receiver is operating.
All the NO outputs of receivers powered by direct current are protected by recovery diodes. Wherever a power
relay or teleswitch is present, the STOP contacts are prepared for running the relay or the teleswitch in order to
