"LENGTH-WEIGHT" chart
and other data are provided in Point 4.2 "Technical Data".
Satisfactory operation requires the correct positioning of the
LIVI 500 operator with respect to the gate; DEA System recom-
mended measurements are shown in F5 page 32.
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. The chart
"LENGTH-WEIGHT" correlating the length of the gate leaf and
its weight in typical situations can be used in selecting the auto-
mation according to the gate to be automated.
We suggest to use the rail arm (art. 560B) with models 501L
and 503L.
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 500 gate operator is always delivered packed in
boxes that guarantee the product adequate protection. Carefully
read any warnings or instructions for storage and handling pro-
vided 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
MALFUNCTION
When the opening command is given,
the gate wing fails to move and the
operator's electric motor fails to start
When the opening command is given,
the motor starts but the gate wing fails
to move
The operator jerks during movement
Operating instructions and warnings
(see also "6 Complete Closing Assembly"); in particular, af-
ter carefully assessing the characteristics of the supports and
the gate, the attachments must also be designed and posi-
tioned according to the angle of opening desired (see F2, F5
Page 31 e 32);
• fasten the bracket and the operator (see F6 page 33);
• assemble carter and arm (see F7 and F8, page 33);
• fasten the arm or the rail to the gate leaf by welding the
attachment or with 4 fixing screws (not included).
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.
WARNING To ensure compliance with regulations and safe
operation of the motor, we recommend to use DEA System
control panels only.
The fastening of the attachments must be performed with
extra attention on both iron pillars and masonry works and gates
of any type.
The necessity of installing reinforcement plates for iron
pillars and gates must be carefully assessed whenever the re-
maining part of the structure does not appear sufficiently strong,
whenever the metal plate used does not appear thick enough or
whenever the morphology of the gate appears to lack solidity.
To install the bracket on masonry posts use appropriate
screw anchors (mechanical or chemical fixing) not included.
Keep all welding seams well protected from corrosion.
Give extra attention to the alignment of the attachments and
their correct vertical positioning.
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 special con-
trol unit for gate operators; see the instructions provided for such
device for further information. When using art. 502EN together
with control panel art. 202RR, use the supplied adaptor cable
by installing it on the control panel and connect to the encoder
reader paying attention to indicated polarity as shown in picture
F12 at page 34.
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.
"TROUBLE-SHOOTING" table
CAUSES / SOLUTIONS
The operator is not receiving correct power supply. Check all connections, fuses,
and the power supply cable conditions and replace or repair if necessary
Check that the unlocking system is closed (see F9, page 33)
Make sure that the electronic device for electric power adjustment is in good
condition
If the wing of the gate does not move freely, release the piston and readjust the
rotation points
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.
