05. 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);
06. 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) .

3.5.3 - Assembling a pole formed of two pieces, either whole or cut.

Possible lengths:
M7BAR: 5,00 m = XBA15 (3,15 m -1,30m = 1,85*) + XBA15 (3,15 m)
6,33 m = XBA15 (3,15 m) + XBA15 (3,15 m)
7,33 m = XBA15 (3,15 m*) + XBA14 (4,15 m)
L9BAR: 7,33 m = XBA15 (3,15 m*) + XBA14 (4,15 m)
8,33 m = XBA14 (4,15 m) + XBA14 (4,15 m)
9,33 m = XBA14 (4,15 m*) + XBA5 (5,15 m)
(*) - CAUTION! – In rods made up of two pieces, it is obligatory to an-
chor the shorter piece to the aluminium support. Point 02 of the pro-
cedure must therefore be changed as follows:
01. Mod . M3BAR - M5BAR - M7BAR: insert the aluminium coupling into one
end of the shorter pole and lock it with the screw provided (fig. 23) .
02. Model L9BAR: insert the aluminium coupling into one end of the shorter
pole and lock it with the screw provided (fig. 24) .
03. Insert the universal joint in the free ends of the two poles . Take care in
correctly 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 im-
pact protection rubber in the slot, through to the end of the pole; then in-
sert 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) .

3.5.4 - Installation of required pole accessories

After installing the pole and the protection rubber, before proceeding any fur-
ther it is important to install any other accessories that may be required on the
pole . For instructions on installation of these accessories, refer to their instruc-
tion manuals .

3.6 - Manually releasing and locking the barrier

This operation is required in the event of a power failure or malfunction .
To manually release or lock the barrier, insert the key provided and turn it 180°
to the right or to the left (fig. 32) .
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).

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. From inside the caisson, pull the U-shaped clip holding the lock cylinder in
place (fig. 33-b) and pull off the cylinder on the outside of the caisson(fig.
33-c);
03. From the other side of the caisson, remove the plastic cap (fig. 34-a) and
insert the lock cylinder into the hole provided (fig. 34-b);
04. Finally, from inside the caisson, insert the U-shaped clip for holding the
locking cylinder in place from below (fig. 34-c) .

3.7 - Limit switch mechanical stop adjustment

01. Manually release the gearmotor: see paragraph 3 .6;
02. Manually move the pole through a complete Opening and Closing ma-
noeuvre;
03. Then use the screws on the mechanical limit switch stops (fig. 35 and 36)
to adjust the horizontal pole setting, when it is closed, and the vertical pole
setting, when it is open .
04. Tighten the nuts well .

3.8 - Pole balancing

Balancing the pole serves to find the best balance between the total pole weight
complete with the accessories installed and the force opposed to it by the ten-
sion of the balancing spring . Proceed as follows to check whether spring ten-
sion is appropriate to balance the weight of the pole and its accessories, if any .

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 clock-
wise (fig. 37-a) . If, on the contrary, the pole tends to drop, increase spring
tension by manually turning it clockwise (fig. 37-b) . Note - the off-balance
6 – English
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. Lock the balancing spring in place with the nut (fig. 37-c);
05. Manually lock the gearmotor: see paragraph 3 .6 .

3.8.2 - L9BAR 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 the nut
clockwise (fig. 38-a) . If, on the contrary, the pole tends to drop, increase
spring tension by turning the nut anti-clockwise (fig. 38-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 value of the nominal torque (for this product, about 6 .5
kg at 1 m) . [(*) force measured at right angles to the pole and at 1 m from
the rotation axis] .
03. Manually lock the gearmotor: see paragraph 3 .6 .

ELECTRICAL CONNECTIONS

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 "Flashing 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 in-
dicator": if programmed with one of these 5 functions on the "LIGHT" out-
put, 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): 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% .
