7.3 - Adding or removing devices

New devices can be added at any time, connected to the BlueBus and Stop
input or those present can be deleted as required. To do this, proceed as fol-
lows:

01.

Press and hold down “

▲

” and “

Set

” keys at the same time;

02.

Release the buttons when LEDs

and

start flashing very quickly (after

approx. 3 s);

03.

Wait a few seconds for the control unit to finish connected device self-
learning;

04.

At the end of this phase, the

STOP

LED must remain lit, while LEDs

and

turn off (where relevant LEDs L3 and L4 start flashing).

After performing this procedure, the automation testing procedure must be per-
formed as described in chapter 5.1.

7.3.1 - Bluebus Inlet

This Bluebus system allows device connections to be made using just 2 con-
ductors for both the electricity supply and the communication signals. All
devices are connected in parallel on the same 2 Bluebus wires, without the
need to observe polarity. Each device is individually recognized because a
unique address is assigned to it during installation. Bluebus can be used to
connect the following: photocells, safety devices, control devices such as key-
boards and readers for transponder cards, indicator lamps, etc. The control
unit recognises each one of the devices connected during the self-learning
phase and is able to detect all possible faults in maximum safety. For this rea-
son each time a device is connected to or removed from Bluebus the self-
learning phase must be repeated, as described in paragraph 4.4.

7.3.2 - Photocells

The Bluebus system enables the control unit to recognise the photocells, con-
trol routing of the relative jumpers (see

Table 11

) and enables assignment of

the correct value for the obstacle detection function. The routing operation is
performed both on TX and RX, positioning the jumpers in the same way with a
check that there are no pairs of photocells with the same address.
The photocells may be installed as shown in

fig. D

Important

– After installing

or removing the photocells, the device learning phase must be performed, as
described in paragraph 4.4.

It is possible to install the TX or RX photocell inside the caisson of the barrier, in
the space provided (

fig. 53

To install the photocell, proceed as follows:

01.

Extract the board of the photocell from its box by prizing it out with a slot-
ted tip screwdriver (

fig. 53-a

IMPORTANT!

- Do not damage the electric

components inside;

02.

Open the box prepared for the photocells, present in the accessory box
(

fig. 53-b

);

03.

Block the board on the bottom of the box (

fig. 53-c

);

04.

Pierce the rubber arranged for the passage of the electric cable (

fig. 53-d

);

05.

Route the electric cable and connect it to the terminal of the photocell (

fig.

53-e

);

06.

Close the bottom of the box with the cover, taking care to block the rubber
in its seat (

fig. 53-f

);

07.

Hook the box on the lens on the side of the caisson by making it slide from
top to bottom (

fig. 53-g

NOTE

– 2 photocells with control function “opens FA1” and “opens FA2” can

be connected to the Bluebus input (it is necessary to cut the A jumper at the
rear of TX and RX cards). When these photocells intervene, the control unit
commands an opening manoeuvre. For further information, refer to the instruc-
tion manual for the photocells.

7.3.3 - MOTB digital selector and proximity reader for MOMB

transponder cards

The Bluebus system enables connection of up to 4 MOTB digital selectors or 4
MOMB transponder badge readers.
MOTB enables control of the automation, by entering one of the memorised
numerical codes on the keypad.
MOMB enables control of the automation by simply placing the memorised
transponder bade close to the automation.
These devices have an individual code, which is recognised and memorised by
the control unit during the phase for learning all connected devices (see para-
graph 4.4).
This prevents an fraudulent attempts to replace a device or use of the automa-
tion by unauthorised persons. For further information, refer to the instruction
manual for MOTB and MOMB.

7.3.4 - STOP Input

The Stop input causes the manoeuvre to stop immediately followed by a short
reverse run. Devices with normally open NO or normally closed NC contact
outputs, optical devices (Opto Sensors), or devices with 8.2 k

constant resist-

ance output such as sensitive edges can be connected to this input. The con-
trol unit, during the learning phase, recognises the type of device connected
and activates a STOP command when any variation in the learnt status occurs.
When set accordingly, more than one device can be connected to the STOP
input, also different from one another;
• Several NO devices can be connected in parallel, with no limit to the number;
• Several NO devices can be connected in series, with no limit to the number;
• Two devices with an 8.2k

constant resistance output can be connected in

parallel; multiple devices must be connected “in cascade” with a single
8.2k

termination resistance;

• An NO and NC type combination is also possible, placing the 2 contacts in

parallel. In this case, a 8.2 k

resistance must be placed in series with the NC

contact; this also enables the combination of 3 devices: NO, NC and 8.2 k

Caution

– If the STOP input is used to connect devices with safety functions,

only the devices with a constant resistance of 8.2 k

or OPTO SENSOR opti-

cal devices guarantee adequate safety levels against faults.
For connection of an optical device type OPTO SENSOR make the connec-
tions as shown in
