Dea LIVI 400 Instrucciones De Uso página 11

4.4 Appropriate conditions of use
The LIVI is designed for installation in sliding gates as an
actuator for the operational automatism as shown in F3 on Page
31. Brackets for both "horizontal" (standard) and "vertical"
(see "PRODUCT ACCESSORIES" table) installation have been
arranged for. The LIVI has been designed and tested for opera-
tion under "normal" civil gate opening conditions; temperature
limits, degrees of protection against dust and water, and other
data are provided in Point 4.2 "Technical Data". Satisfactory
operation requires the correct positioning of the LIVI operator
with respect to the gate; DEA System recommended measure-
ments are shown in F3 page 31. The automatism required must
be selected according to the gate to be moved; the attrition on
the attachments, the weight, the length/height of the gate wing,
and the degree of closing of the surfaces are the elements to be
considered.
WARNING The use of the product under unusual conditions
not foreseen by the manufacturer can create situations of dan-
ger, and for this reason all the conditions prescribed in these
instructions must be respected.
WARNING Under no circumstances must the product be
used in explosive atmospheres or surroundings that may prove
corrosive and damage parts of the product.
4.5 Instructions for risk-free operation
4.5.1 Transport
The LIVI gate operator is always delivered packed in boxes
that guarantee the product adequate protection. Carefully read
any warnings or instructions for storage and handling provided
on the box.
4.5.2 Installation, assembly and disassembly
The following operations are essential to the correct laying
of the product:
• The careful definition of the entire automatic opening layout
(see also paragraph "6 Complete Closing Assembly");
in particular, after carefully assessing the characteristics
of the place you have selected, define model and correct
positioning of the foundation base (see F3, pages 31);
• screw in the foundation base (see F8 page 32) or put it in
concrete with item nr. 460;
• Check carefully the correct positioning of the foundation
base;
• Screw LIVI and the foundation base together using
appropriate screws (see F7 page 32);
MALFUNCTION
When the opening or closing
command is activated the gate
leaf fails to move and the opera-
tor's electric motor fails to start.
When the opening command
is activated, the motor star-
ts but the gate leafs fail to
move
The gate moves by fits and
starts, it is noisy, it stops at
half run or it does not start
Operating instructions and warnings
"TROUBLE-SHOOTING" table
The operator is not receiving correct power supply. Check all connections, fuses, and the
power supply cable conditions and replace or repair if necessary. If the gate does not close
check the correct functioning of photocells.
Check that the unlocking system is closed (see F9, page 32)
Check the electronic force adjustment device and the mechanical clutch
ake sure that the motor does not push in the opposite direction, the limit switch electrical
connections might be reversed
Make sure that nothing hinders the gate wheels movement and the slide in which they roll;
There always must be backlash between rack and pinion; make sure the rack is accurately
positioned.
The power of the gearmotor may be insufficient for the characteristics of the gate's wing;
check the choice of model whenever requiredh
If the operator attachment to the gate bends or is badly fastened, repair and/or buttress it.
WARNING All installation, maintenance, cleaning or repair
operations on any part of the system must be performed exclu-
sively by qualified personnel with the power supply discon-
nected working in strict compliance with the electrical standar-
ds and regulations in force in the nation of installation.
4.5.3 Starting
The installation of the product requires masonry and/or wel-
ding and electrical connection operations using adequate equi-
pment for the job in complete respect of the accident-prevention
standards and regulations in force in the nation of installation.
The product must be electrically connected to a gate ope-
rator control board which is built-in in some LIVI models; see
the instructions provided for such device for further information.
4.5.4 Use
The product is destined for incorporation in the assembly of
devices that comprise the gate's automatism. DEA System assu-
mes that it will always be used in compliance with the standards
and regulations in force.
All LIVI models have an unlocking system; the working of
this system is the following: after unlocking the lock on the han-
dle (protected by a plastic cover) turn the lever in the direction
shown in F9, page 32; the operator is now unlocked and, if no
obstructions hinder its movement, the gate can now move freely.
The opposite procedure, that is the rotation of the lever up to
the limit switch and the locking of the lock (remember to protect
the lock with the appropriate cover) returns LIVI to its normal
working conditions.
4.5.5 Adjustment
Each LIVI model is equipped with a limit switch whose ope-
ration must be adjusted on site. DEA System supplies two limit
switch cams (see F4 page 30) which must be installed on the
gate rack and subsequently adjusted so as to guarantee the
gate functionality and safety distance both during opening and
closing. Some LIVI models are equipped with mechanical clutch
to limit the pressure of the gate against an obstacle obstructing
its travel while opening or closing. Follow these instructions to
adjust it (see F6 page 31):
•disconnect power supply to the operator;
•hold firmly the motor shaft with a wrench while rotating the
grub screw with an Allen wrench (turn clockwise to increase
force, and turn counterclockwise to reduce force);
