EDGE LIGHT 

= this is a 12 V/21 W indicator light which can be configured in 

various ways, by means of the Oview programmer . With the factory setting, it 

performs the flashing light function, flashing at intervals of 0.5 s lit and 0.5 s 

off. With the edge light, diagnostic flashing is performed.

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 setting).

• 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 (

Fig. 32

) .

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 (

Fig. 33

) .

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: pole closing, opening and closing.

06. 

Press “

Open

” for the pole to run a complete Opening manoeuvre .

07. 

Press “

Close

” for the pole to run a complete Closing manoeuvre .

During these manoeuvres, the control unit memorises the force required to 

complete these manoeuvres .

CAUTION!  –  The  learning  phases  must  never  be  interrupted. 

If this 

occurs, the entire learning procedure must be repeated .

At the end of the learning phase, if leds “L3” and “L4” flash, this means that 

there is an error . The phase for learning the mechanical stops can be repeated 

at any time, also after installation (for example, if the position of a mechanical 

stop is moved) .

IMPORTANT 

– The deceleration points are calculated automatically by the 

control unit; after the position search phase, at least 2 or 3 complete manoeu-

vres must be performed before that control unit can correctly calculate the 

points of deceleration .

4.6 - Pole movement check

After learning the devices and completing the 2-3 manoeuvres to calculate 

deceleration, a number of Opening and Closing manoeuvres should be per-

formed to ensure correct pole movement .

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. 29

);

02.

  Route the electric cables inside X-Bar, 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. 30

);

04.

  Connect the other cables as shown in the wiring diagram in 

Fig. 31

 .  

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” - “activated 

if pole is open” - “flashing light for pole lights” and “maintenance 

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 .
