ELECTRICAL CONNECTIONS

4

CAUTION! – All electrical connections must be made with the unit dis-
connected from the mains power supply.

01.

Remove the cover by loosening the screws and turning the key clockwise
(

fig. 39

);

02.

Route the electric cables inside the barrier, starting from the base towards
the control unit and routing them to the left. Instead, the cables of the Loop
detectors and for the “Master-Slave” mode must be made by routing them
to the right;

03.

Route the power supply cable through the cable gland and connect them
to the 3-contact terminal with fuse. Tighten the cable gland by tightening
the screws (

fig. 40

);

04.

Connect the other cables as shown in the wiring diagram in 

fig. 41

. 

Note –

To facilitate cable connections, the terminals can be removed from their
seats.

4.1 - Description of the electrical connections

• LIGHT

= this output is programmable (see Chapter 6, paragraph 6.2 - Level

2 programming - adjustable parameters) to connect one of the following
devices:

– Flashing light

: if programmed as “flashing light” on the “LIGHT” output,

a NICE flashing light model “LUCY B, MLB or MLBT” with a 12 V 21 W car
type lamp can be connected. During the manoeuvre it flashes at intervals of
0.5 s lit and 0.5 s off. Factory setting: configuration for operation as “Flash-
ing light for pole lights” 24 V/10 W.

– “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 “LIGHT”

output, a 24 V indicator (max. 10 W) can be connected for the following sig-
nals:

“Pole open indicator” function

Pole closed: Off

Pole opening: slow flashing light

Pole closing: quick flash light

Pole open (not closed): on

“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
seconds 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 =
number 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). Dur-
ing 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 connect-

ed (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.

• 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.

3.5.3 - Pole assembly (6 metres / 9 metres)

01.

Assemble the two plastic pole insertions (

fig. 23

);

Important:

to compose the required pole, use the pole accessory as

described below:

6 m pole

= 2 pieces XBA15 mod.

7 m pole

= 1 piece XBA15 mod + 1 piece XBA14 mod.; 

IMPORTANT! -

Position the XBA15 mod. pole first (3150 mm)
8 m pole

= 2 pieces XBA14 mod.

9 m pole

= 1 piece XBA14 mod + 1 piece XBA5 mod.; 

IMPORTANT! -

Position the XBA14 mod. pole first (4150 mm)

02.

Insert, from the same end of the pole, the insertions just assembled. Use a
rubber mallet (

fig. 24

);

03.

Insert the universal joint in the free ends of the two poles. Take care in cor-
rectly directing the joint since the heads of the screws must be on the
same part of the holes on the poles (

fig. 30

);

04.

Act to the same degree on the three screws of the joint by loosening them
in a way to “expand” the joint inside the poles (

fig. 31

);

05.

Lightly grease the aluminium guide on both sides (

fig. 25

);

06.

Perform this operation on both ends of the pole: insert the first part of impact
protection rubber in the slot, through to the end of the pole; then insert the
joint for the impact protection rubber (

fig. 26

) and repeat with all parts;

07.

The impact protection rubber may protrude by about 1 cm from the end of
the profile (

fig. 27

):

A)

position the pole plug and lock it with the two screws (

fig. 28

);

B)

position and block the two rubber cover plugs (

fig. 28

);

08.

Insert the pole assembly in the pole support shell, pushing it up to the end
and then tighten the 6 previously inserted support screws fully down (

fig. 29

).

3.6 - Manually releasing and locking the barrier

This operation is required in the event of a power failure or malfunction.

IMPORTANT!
– The release and locking operations must be performed only when the
pole is horizontal and stationary.
– It is possible to carry out the manual release and lock on both sides of
the barrier by moving the locking cylinder (see paragraph 3.6.1).

To manually lock and release the barrier, insert the key supplied and turn it by
180° (

fig. 32

); the key can be turned to the left or to the right.

3.6.1 - How to move the locking cylinder for manual release and lock

01.

Insert the key supplied and turn through 180° clockwise (

fig. 33-a

);

02.

Remove the locking cylinder by using a wrench (

fig. 33-b

and 

33-c

)

03.

From the other side of the caisson, remove the rubber plug (

fig. 33-a

);

04.

Position the ring nut and insert the locking cylinder inside the pre-drilled
hole and lock it as shown in 

fig. 34-b

and 

34-c

.

3.7 - Mechanical stop adjustment

01.

Manually release the gearmotor: see paragraph 

3.6

;

02.

Manually move the pole through a complete Opening and Closing manoeuvre;

03.

Then adjust the mechanical stop screws (

fig. 33 

and

34

) to align the pole

vertically and horizontally;

04.

Tighten down the nuts.

3.8 - Pole balancing

The pole needs to be balanced to establish the best balance between two fac-
tors: the 

weight

of the pole and any accessories and the counterposed 

force

of the balancing spring. The latter individually guarantees the balancing of the
pole; if this rises or lowers, proceed as described in the paragraphs below.

3.8.1 - M3BAR / M5BAR / M7BAR Pole balancing

01.

Manually release the gearmotor: see paragraph 

3.6

;

02.

Manually move the pole to mid-travel (45°) and leave stationary. If the pole
tends to lift, reduce the tension of the spring by manually turning it clockwise
(

fig. 37-a

). If the pole tends to lower, reduce the tension of the spring by

manually turning it anti-clockwise (

fig. 37-b

). 

Note - the off-balance value is

only acceptable when the force required to move the pole

*

when open,

closed and in all the other positions, is lower than or equal to half of the
nominal value (equal to about 1.5 kg for M3; 3.5 kg for M5 and 4.5 kg for
M7, about 5 kg at 1 m).

[(

*

) force measured at right angles to the pole and at

1 m from the rotation axis].

03.

Repeat point 02 positioning the pole also at approx. 20° and approx. 70°. If
the pole remains still in position, this means that balancing is correct; a slight
off balance is admissible, 

but the pole must never move significantly

.

04.

Tighten the nut to lock the balancing spring (

fig. 37-c

);

05.

Manually lock the gearmotor: see paragraph 

3.6

.

3.8.2 - LBAR Pole balancing

01.

Manually release the gearmotor: see paragraph 

3.6

;

02.

Manually move the pole to mid-travel (45°) and leave stationary. If the pole
tends to rise or lower, it is necessary to use the nut (

fig. 38

) to increase or

decrease the tension of the spring. 

Note - the off-balance value is only

acceptable when the force required to move the pole

*

when open, closed

and in all the other positions, is lower than or equal to half of the value of
the nominal torque (for this product, about 6.5 kg at 1 m).

[(

*

) force meas-

ured at right angles to the pole and at 1 m from the rotation axis].

03.

Manually lock the gearmotor: see paragraph 

3.6
