• 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) .
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
observance of current local standards.
Connect the control unit to an electric power line equipped with an earthing
system . The power supply line must be protected by suitable magneto-thermal
and differential switches . 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 is off (with factory set-
ting) .
• Ensure that the light on the control unit is switched off .
If the above conditions are not satisfied, switch off the power supply to the
control unit and check the electrical connections previously made .
For more useful information see also chapter “7 Troubleshooting” .
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 posi-
tions 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 .
CAUTION! – All electrical connections must be made with the unit dis-
connected from the mains power supply.
01.
Loosen the screws of the cover ( fig. 25 );
02. Route the electric cables inside S4BAR, starting from the base towards the
control unit and routing them to the left;
03.
Connect the wires of the electric power cable to the 3-contact terminal
with fuse and secure the cable with the collar (
fig. 26
);
04. Connect the other cables as shown in the wiring diagram in fig. 27 .
Note – To facilitate cable connections, the terminals can be removed from
their seats .
4.1 - Description of the electrical connections
• FLASH = this output is programmable (see Chapter 6, paragraph 6 .2 - Lev-
el 2 programming - adjustable parameters) to connect one of the following
devices:
– Flashing light : if programmed as “flashing light” on the “FLASH” output,
a NICE flashing light model “LUCY B, MLB or MLBT” with a 12 V 21 W car
type lamp. During the manoeuvre it flashes at intervals of 0.5 s lit and 0.5 s
off .
– “pole open indicator” - “activated if the pole is closed” - “acti-
vated if pole is open” - “flashing light for pole lights” and “main-
tenance indicator”
: if programmed with one of these 5 functions on the
“FLASH” output, a 24 V indicator (max. 10 W) can be connected for the
following signals:
“Pole open indicator” function
Pole closed: Off
Pole opening: Slow flashing light
Pole closing: Quick flash light
Pole open (not closed): lit
“Active if pole closed” function
Pole closed: On
All other cases: Off
“Active if pole open” function
Pole open: On
All other cases: Off
Function “flashing light for pole lights”
The indicator light or pole lights indicate execution of the manoeuvre in
progress by flashing constantly at regular intervals (0.5 sec on; 0.5 sec-
onds off)
Function “Maintenance indicator”
- indicator lit on for 2 seconds at the start of the opening manoeuvre =
number of manoeuvres less than 80%
- flashing light indicator during execution of the entire manoeuvre = num-
ber of manoeuvres between 80 and 100%
- indicator constantly flashing = number of manoeuvres greater than
100%.
– 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 con-
nected (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 manoeu-
vre 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 release the pole and complete the manoeuvre . In the closing manoeuvre
ensure that the electric lock re-engages mechanically .
• 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 .
