8.7. GENERAL FUNCTIONS
CONTROL BOARD
The regulator is prepared for mana-
gement of different machine models
depending on the position of the DIP
switches present on the control.
To select the AIR-CONDITIONING mo-
del, the DIP switches must be set ac-
cording to the layout shown here. The
control and all loads must be discon-
nected from the main power supply.

8.8. TERMINALS CONNECTION
NETWORK - CONTROLS.
8.8. 1 . Electric connections
Shielded and twisted bipolar cables
must be used to connect the terminals
to the control or the controls network,
at the relative clamps indicated on the
terminal and on the control panel.
The maximum distance from the termi-
nal from the relative control is 30 m.
The power supply voltage is 24 Vdc
with data transmission on the twisted
pair connection cable with packs at a
transmission speed of 4800 bit/s and
proprietor protocol.

mounted in the different versions to ge-
nerate different product codes depen-

All parameters will be configurable and
many functions present can be acti-
vated according to requirements and
applications.
The inputs and outputs will all be con-
figurable via software in the different
functionalities for greater flexibility and
easy installation.
