CAUTION:
(1) Because most of the customers do not use X3 port, the X3 relay is selected spare parts,
ordered according to customer needs.
(2) The encoder must be used with FCU. Because most of the production line are moving at
the same speed, the encoder and FCU are selected spare parts, ordered from Saturn. For
standard S480 model, FCU has already been set inside.
