Connection of the Graphic terminal (standard)
The terminal can be installed at a maximum distance of 500 metres
from the control board.
Up to 50 metres, it can be connected directly with telephone wire.
From 50 to 200 metres, it is necessary to use the TCONN bypass
cards and AWG 20/22 shielded cable with 2 twisted pairs.
From 200 to 500 metres, it is necessary to use the TCONN bypass
cards, AWG 20/22 shielded cable with 1 twisted pair and external
20...30Vdc (150 mA) power supply.

Connection of the User terminal (optional)
The terminal can be installed on the RS485 Filed-bus at a maximum
distance of 100 metres from the control board.
The connection requires the following:
Power supply at 230Vac 50/60Hz (L&N): 2 wires (section 0.5 at
1.5 mm
2
).
Note: The power supply of the electrical cabinet (230 V) must be
used for terminal power.
Communication with the board (RX+/TX+ & RX-/TX-): shielded
cable type AWG20 or AWG22 with 1 braided pair + drainwire +
shielding (e.g., model BELDEN 7703NH).

Important: It is recommended to insert an electrical resistance of
120, between connectors TX+ and TX- of the board output and
on the fi nal component of the RS485 network, to avoid potential
problems of communication.
Confi guration:
To ensure communication between the User terminal and the control
board, the terminal must be confi gured with address 10 and speed
19200 bps.
The terminal is sent addressed, and on the power up, the screen
should display the fi rmware version “1.1” on the power up and, then,
the “
init” symbol. The terminal will be fully operational after a
few seconds.
In the unlikely event of a communications failure the screen will
display “
Cn”. Please make sure to check connections and the
fi rmware version.
14.2. Connection of terminals to the control board
14 - CONECTIONS
Confi guration:
To ensure communication between the Graphic terminal and the
control board, the terminal must be confi gured with address 16.
In the event of a terminal supplied separately, this is not sent
addressed and the following procedure must be carried out:
1) Simultaneously press the
+ + keys.
2) On the screen accessed, set address 16 in:
Display address setting.
