Instruction Manual
Radio control devices T3, T5 and T7.
version 1.4 Genn. 10
OPERATING PRINCIPLE
Description of the Transmitter
The commands given with the buttons are processed by the
microprocessor which constructs the coupling telegram including the
univocal code and sends it to the radio transmission module.
Description of the Receiver
The coupling telegram received by the radio receiving module is
processed by both microprocessors μPA and μPB which check its
authenticity, comparing it with the univocal code. If the data received
are valid, microprocessor A activates the Safety Relays while
microprocessor B activates the relays of the controls.
In the case of active or passive emergency commands, lack of radio
signal or disturbance, the microprocessors A and B both block the
operating machine.
The processing of the data is carried out independently in the two
microprocessors. This means that safety is always guaranteed even
in the case of a breakdown of one of the two microprocessors
(redundant safety system).
