INSTALLATION INSTRUCTIONS
• The ground must be stable enough to firmly hold the plinth and the
anchor plates.
• Where possible protect the barrier cabinet from accidental knocks by
passing vehicles.
• Work out the run of the cables according to the command and control
devices fitted and make sure the system conforms to the local standard
and regulations in force (see installation example fig.1 pag. 2).
It is very important that the barrier be well fixed to the fasten-
ing base as the ground anchors could loosen throughout time
due to movement and vibration and cause damage to the
cabinet.
FITTING THE UNIT (fig.3-3a)
Prepare a cement base with the base plate and anchors "A" embed-
ded. The cable passage pipe "B" and the four threaded bolts M12 must
protrude (30mm) from the base plate.
The base plate must be perfectly in square, its surface must be clean
and the four threaded bolts must emerge perpendicularly.
Note: the cement base should preferably protrude 50 mm out of the
ground in order to avoid water build up which could damage the appli-
ance. Remove the 4 self-locking nuts "D" from the four threaded bolts
(used to fasten down the anchors) and insert the base of the barrier "C".
Fasten down the barrier using the 4 self-locking nuts "D" and washers
supplied with the appliance. It is also possible to fasten the barrier to
an already existing cement base as long as the thickness of the base is
great enough to guarantee a strong hold for the rawlplugs.
We advise you to use the following type of rawlplug: "Steel anchor bolts
M12/Ø20 for heavy duty use".
OPENING THE ACCESS DOOR/FLIP-BACK HOOD (fig.8)
Use the supplied key to open the access door or the flip-back hood.
Opening the access door forces the passive safety microswitches at
positions "U" and "V" to cut in so blocking the command functions (the
indication "StOP" will appear flashing on the display; see page 21).
To activate the control unit you will have to block the microswitch in the
closed position. If the boom isn't completely closed the control unit will
start a pre-flashing sequence for 10 seconds before closing; to avoid
this function press the "PROG" button briefly.
You are however always advised to shut off the power at the mains
before accessing the internal components.
ASSEMBLING THE STANDARD BOOM (fig. 4-5)
The boom is supplied complete with the following:
- flashing warning leds
- rubber profile
The boom lights are pre-wired and are fitted with a fast-fitting jack.
1) Pass the wiring cables through the boom holder before fitting the
boom into its seat.
2) Insert the fastening plate "H" (fig. 5) into the lower groove of the boom.
This will allow boom to be fixed to the cabinet.
3) Insert the boom into the boom holder "I" and fasten down using the
screws "J".
4) Connect the wiring to the control unit following the diagram (fig. 18)
5) Once you have completed the wiring carry out a few trial manoeu-
vres.
ASSEMBLING THE ARTICULATED BOOM 716/EL3424ASKU
(fig.6)
The boom should be prepared in the same way as shown in the para-
graph "Assembling the standard boom" (fig. 5) for the end cap "K"
and the rubber buffer "G" which should be divided into two parts.
1) Fasten the support "29" to the upper internal plate of the barrier
in the front position with the door open using the two screws "31"
and relative washers "30".
2) Position part "24" inside the boom holder sleeve over the rotation
pin and fasten down along with bracket "25" using the two screws
"4".
3) If you wish to shorten the boom it can be done to both the first part
(the part that is inserted into the boom holder) by shortening it at
a distance of 100 to 200 mm from the end and then shortening
the tie rod "22" by the same distance (shorten the chain "20" by
moving the chain clip "16"), as well as to the end part which can
be shortened by up to 500 mm.
Once you have completed the above mentioned operations, move
the boom holder to a vertical position and slide the boom completely
in from the top after having loosened the screws "Q" by three or
four turns as described in the paragraph "Assembling the standard
boom".
During this stage the boom remains at 90° as the chain will not yet
allow a greater rotation.
While you are inserting the boom watch out for the threaded tie rod
which protrudes from the inside of the boom as it has to be passed
over the "chain guide" part "24" and then passed through the hole
"P" and temporarily fastened to the support "29" (to fasten it you will
require the two nuts "28" one above and one below the support).
Calibrating the articulated boom:
- fasten down the screws "Q"
- carry out a closing manoeuvre. Make sure that the boom is hori-
zontal and completely lined up with the rest of the boom.
You should adjust the first part of the boom following the instructions
in the paragraph "mechanical adjustment of the horizontal posi-
tion of the boom" and then adjust the head of the boom by means
of the nuts "28".
Attention: the pull carried out by the tie rod "27" (caused by tighten-
ing the nuts) must be slightly greater than the effect of the dropping
of the head of the boom (not very tight). In fact over tightening will
put stress on the chain inside the boom and cause it to wear rapidly
leading to a loss of drag force.
ASSEMBLING THE FIXED SUPPORT POLE (fig. 7)
The fixed support pole is positioned at the head of the boom and func-
tions as a reference point for the closing of the barrier.
When the boom is moving it should never crash into the support pole
but should rest lightly against it instead.
The rubber buffer normally covers the entire length of the boom.
If you are using a support pole the buffer should be slid back towards
the boom holder so as to free the space required for the head of the
boom to rest against the support pole.
Prepare a cement base in which the anchor plate "S" is to be inserted
(make sure that the M8 threaded bolts are protruding by 30 mm).
The base must be perfectly level, the threaded M8 bolts must emerge
perpendicularly and be perfectly clean.
Unscrew the four self-tapping screws "D" on the four threaded bolts
(needed to block the anchors fig. 3a) and insert the base.
Fasten down using the supplied nuts and washers.
It is also possible to fix the base of the support to cement base or
pavement which already exists as long as it is wide enough and strong
enough to take the anchor bolts.
We advise you to use the following type of rawlplug: "Steel anchor bolts
M8/Ø14 for heavy duty use".
MECHANICAL ADJUSTMENT OF THE HORIZONTAL POSITION OF
THE BOOM (fig. 9)
Connect the power to the electronic programmer (page 19) and then
press the closing button so that the boom is stopped by the closing
travel limit micro-switch.
To adjust the horizontal position of the boom you must not alter the
microswitch located under the plate (this microswitch intercepts the
geared reduction lever and stops it at the closed position giving the
maximum deceleration to the boom).
The intervention is to be carried out on the adjustable tie rod "Z" after
having loosened the nuts "J" (threaded to the left) and "K" (threaded
to the right). One clockwise turn of the component "Z" (figure 9a) will
lower the head of the boom. One anticlockwise turn of the component
"Z" (figure 9b) will heighten the head of the boom.
For booms fitted with a fixed support pole you are advised to let all the
weight rest on the ground so that the articulated component "W" is free
and can be moved manually. Tighten the locknuts "J" and "K" making
sure that the upper articulated joint is aligned with the lower joint.
Attention!: Each time the horizontal position of the boom is
adjusted using the tie rod, the opening direction travel limit
microswitch must also be adjusted (see the following chap-
ter)
ADJUSTING THE OPENING DIRECTION TRAVEL LIMIT MICROS-
WITCH FOR THE VERTICAL POSITION OF THE BOOM (fig.10-11)
After adjusting the horizontal position of the boom proceed as follows:
1) Loosen the setting screw "X" by four or five turns so that it anticipates
the intervention of the microswitch "A1".
2) Lower the rubber buffer "Y" by three or four turns after having released
it from the nut locking it to the plate.
3) Carry out a trial manoeuvre to see if the boom comes to rest vertically
or as near as possible to the vertical position.
