– Suction cup: a 24V max 10W suction cup can be connected (versions
with electromagnet only, without electronic devices) . When the pole is closed,
the suction cup is activated to lock the pole in place . During the opening and
closing manoeuvre it is deactivated .
– Electric block: a 24 V max 10 W electric block with latch can be connect-
ed (versions with electromagnet only, without electronic devices) . During the
opening manoeuvre, the electric lock is activated and remains active to free
the pole and perform the manoeuvre . In the closing manoeuvre ensure that
the electric block re-engages mechanically .
– Electric lock: a 24 V max 10 W electric lock with latch can be connected
(versions with electromagnet only, without electronic devices) . At the start of
the opening manoeuvre, the electric lock is activated for a short period to re-
lease the pole and complete the manoeuvre . In the closing manoeuvre en-
sure that the electric lock re-engages mechanically .
• FLASH = this output is programmable by using the Oview programmer . It is
possible to connect the same devices of the LIGHT output . In the factory it is
configured for operation with flashing light 12 V 21 W .
• SCA = this output is programmable by using the Oview programmer . It is
possible to connect the same devices of the LIGHT output . In the factory it is
configured for operation with Pole Open Indicator 24 V 10 W .
• BLUEBUS = this terminal enables the connection of compatible devices; all
are connected in parallel with just two wires conveying the electric power and
communication signals . For further details see Chapter 8 .
• STOP = input for devices that block or shut down the manoeuvre in pro-
gress; by setting the input accordingly, it is possible to connect Normally
Closed type contacts, Normally Open contacts, constant resistance or opti-
cal devices . For further details see chapter 8 .
• PP = input for devices control movement in Step-Step mode, enabling the
connection of Normally Open contacts .
• OPEN = input for devices which control only opening manoeuvre . NO con-
tacts can be connected to this input .
• CLOSE = input for devices which control only closing manoeuvre . NO con-
tacts can be connected to this input .
• AERIAL = input for connection of the aerial for the radio receiver (the aerial is
incorporated on LUCY B, MBL, MLBT) .
• LED BOARD OUTPUT = this output is programmable (see Chapter 6, par-
agraph 6 .2 - Level 2 programming - adjustable parameters) and is used
to connect the led flashing light board (XBA7) or the led traffic lights board
(XBA8) . With the factory setting, it performs the flashing light function, flash-
ing at intervals of 0 .5 s lit and 0 .5 s off . In addition, diagnostic flashing is per-
formed .
• LOOP1 = Loop Detector input to connect a loop detector, for the detention
of metal masses . The operating modes associated to this input may be mod-
ified with the Oview programmer (see paragraph 7 .5 – Loop Detector) . Fac-
tory setting: configuration for the opening manoeuvre
• LOOP2 = Loop Detector input to connect a loop detector, for the detention
of metal masses . The operating modes associated to this input may be mod-
ified with the Oview programmer (see paragraph 7 .5 – Loop Detector) . Fac-
tory setting: configuration for the opening manoeuvre .
• MASTER-SLAVE = connector for the connection of 2 barriers in Master-
Slave mode (see paragraph 7 .6 – Master-Slave) .
IMPORTANT! – NEVER CONNECT DEVICES OTHER THAN THOSE SPE-
CIFIED.

4.2 - Initial start-up and electrical connections

CAUTION! – The final connection of the automation to the electrical
mains must be made exclusively by a qualified skilled technician, in ob-
servance of current local standards.
Connect the control unit to an electric power line equipped with an earthing
system . Envisage a mains disconnect device, with a contact opening distance
that ensures complete disconnection in the conditions of overvoltage category
III, or envisage a plug and socket system .
After powering up the control unit, perform the following checks:
• Make sure that the "Bluebus" led flashes quickly for a few seconds and then
regularly with a frequency of about one flash per second .
• If photocells are present, check that the leds on the latter also flash (both on
TX and RX elements); the type of flash is not significant as this depends on
other factors .
• Check that the device connected to the FLASH output or XBA7 led flashing
light is off (with factory setting) .
If the above conditions are not satisfied, switch off the power supply to the con-
trol unit and check the electrical connections previously made .
For more useful information see also chapter "8 Troubleshooting" (trouble-
shooting guide) .

4.3 - Pre-set functions

The control unit is equipped with a series of programmable functions, which
are factory set with the most commonly used values . These values can be
modified at any time: See chapter 6 .

4.4 - Recognition of the connected devices

After the initial power-up, the control unit must be able to recognise the devices
connected on the inputs "Bluebus" and "Stop" .
CAUTION! – The learning phase must be performed even if no device is
connected to the control unit.
To indicate whether this operation is necessary, leds "L1" and "L2" on the con-
trol unit emit a number of flashes .
01. Press and hold down "Open" and "Set" keys at the same time;
02. Release the keys when LEDs L1 and L2 start
flashing quickly (after approx . 3 seconds) .
03. Wait a few seconds for the control unit to
complete the device learning phase . At the
end of this phase, the "Stop" led must be
lit and leds "L1" and "L2" must turn off (leds
"L3" and "L4" may start flashing to indicate
that the positions have not be learnt) .
This procedure must be repeated in the case of modifications to the devices
connected to the terminals BlueBus and Stop; for example, after connecting a
new device to the control unit .

4.5 - Recognition of limit positions on opening and closing

After learning the connected devices, the control unit also has to learn the po-
sitions of the mechanical stops . In this phase, the pole travel distance is read,
measured from the closing mechanical stop to the opening mechanical stop .
01. Manually release the gearmotor (see chapter 3 .6) and manually position
the pole at approx . 45° (mid-travel);
02. Lock the gear motor (see paragraph 3 .6);
03. Press and hold down "Close" and "Set" keys at the same time;
04. Release the keys when the manoeuvre starts (after approx . 3 seconds);
05. Wait a few seconds for the control unit to
complete the position learning phase: close,
open and close of the pole, with intervals with
a 3 second pause .
Warnings! • Do not interrupt the three ma-
noeuvres: if they are interrupted, it will be nec-
essary to repeat the entire procedure from
point 01 . • While performing the three ma-
noeuvres, make sure that the pole balancing
lever hits the mechanical stops on the limit switches . If this does not hap-
pen, stop the procedure, adjust the mechanical stops on the limit switch
and repeat the procedure from point 01 . • If leds "L3" and "L4" flash after
completion of the three manoeuvres, an error has occurred . In this case,
repeat the entire procedure starting from step 01 .
IMPORTANT! – The parameters concerning the deceleration positions and the
braking intensity, are functions preset by the unit . In any case it is possible to
modify them by directly acting on the unit, modifying the parameters "L5 Long/
short deceleration (see Table 6 - paragraph 6 .1)" and "L8 Braking (see Table
6 - paragraph 6 .2)" or by using the Oview programmer .

4.6 - Pole movement check

After learning about the devices, a number of Opening and Closing manoeu-
vres should be performed to ensure correct pole movement .
01. Press "Open" to activate an Opening manoeuvre; ensure that the pole
starts to decelerate before reaching the opening position;
02. Press "Close" to activate a Closing manoeuvre; ensure that the pole starts
to decelerate before reaching the closing position;
03. Make sure that the led flashing light, if present, flashes at regular intervals
(0 .5 sec on, 0 .5 sec off) during a manoeuvre;
04. Run a number of Opening and Closing manoeuvres to ensure that there
are no points of increased friction or malfunctions .
CAUTION – If the manoeuvre starts from a position different from that of one
of the mechanical stops (opening or closing), it is performed at low speed .
