3.1. GENERAL DESCRIPTION
The receiving unit consists of a box inside which are the different electronic systems for the
reception of commands and the activation/deactivation of the relays required for each machine
manoeuvre.
The receiver assembly can be divided into three blocks (Fig. 3.1.), UHF receiver, control circuit and
relay circuit.

The signal captured by the antenna is injected to the receiver, which supplies the microprocessor
with a low frequency signal in FFSK code. The control module is in charge of checking that the
information received is free of errors, then elaborating the pertinent commands to activate the
opportune relay.
For GCFI models, the transmitter becomes a transceiver in order to establish two-way
communication with the transmitter.
