Product Description And Intended Use; Installation; Preliminary Checks For Installation; Product Application Limit - Nice M3BAR Instructions And Warnings For Installation And Use

lously the provisions in the "Maintenance Schedule" Section (removable insert
at the end of the manual) .
• Mechanical resistance and stability
The product is designed and manufactured so that the forces, impacts and
stress incurred during normal use do not cause any damage or jeopardise its
mechanical performance .
Warning: See notes to the requirement "Safe opening for vertically moving
doors" .
• Operating forces for power-operated closures
The operating forces exerted by the boom with regard to the risks of crushing
and impact are safeguarded against by means of one of these three methods:
1 For operation with "hold-to-run command" (man present): as specified
in EN 12453 . In this case the command button must be placed in view of the
automation and if it is accessible to the public, the command button must not
be available to them, e .g . use only with a key switch .
2 For "Semi-automatic" operation: by limiting the forces as specified in EN
12453 .
3 For "automatic" operation: by limiting the forces as specified in EN 12453;
in this case, at least one pair of photocells must necessarily be installed as
shown in Fig . 1 .
Special warning to ensure continued compliance with the requirement:
see notes to the requirement "Safe opening for vertically moving doors" .

PRODUCT DESCRIPTION AND INTENDED USE

MBAR and L9BAR are electromechanical road barriers for residential and in-
dustrial use; they control the opening and closing of a road transit point with
widths from 3 to 8 metres .

IMPORTANT! – All uses other than the intended use described and use
in environmental conditions other than those described in this manual
should be considered improper and forbidden!
These barriers are fitted with an electromechanical gearmotor with a 24 V mo-
tor, with incorporated Loop Detector for 2 magnetic loops, with electric limit
switch system and a flashing light signal which can be incorporated in the lid
(optional accessory) . These two models may be installed as counterposed bar-
riers in "Master-Slave" mode to cover a surface of a road transit point exceed-
ing 8 metres (see paragraph 7 .5) .
The control unit is set up for connection to devices belonging to the Nice Op-
era system and to the "Solemyo" solar power system (see paragraph 4 .10 .3) .
The barriers run on electric energy and in the event of a power failure the pole
can be released and moved manually . Alternatively the buffer battery model
PS224 can be used (optional accessory - see paragraph 4 .10 .2), which guar-
antees a number of automation manoeuvres in the first few hours of power fail-
ure . Should you desire to prolong this period or extend the number of manoeu-
vres, the Stand by function should be enabled (see table 6) .
Important points on consulting the manual
- In this manual, the words "road barrier" refer to the two products "MBAR" and
"L9BAR" .

INSTALLATION

3.1 - Preliminary checks for installation

Before proceeding with installation, check the condition of the product compo-
nents, suitability of the selected model and conditions of the intended installa-
tion environment .
• Ensure that all material used is in perfect condition and suitable for use .
• Ensure that all product application limits can be observed (see paragraph
3 .2) .
• Ensure that the selected installation environment is compatible with the over-
all dimensions of the product (fig. 2) .
• Ensure that the selected surfaces for barrier installation are solid and guaran-
tee a stable fixture .
• Make sure that the fixing zone is not subject to flooding . If necessary, mount
the barrier raised from the ground .
• Ensure that the space around the barrier enables easy and safe completion
of manual manoeuvres .
• Ensure that there are no obstacles along the pole trajectory which prevent the
opening and closing manoeuvres .
• Ensure that each device to be installed is in a sheltered location and protect-
ed against the risk of accidental impact .

3.2 - Product application limit

Before installing the product, ensure that all values specified in the chapter
"Technical product specifications" are compatible with the intended use .
– Ensure that the estimated durability (see paragraph 3 .2 .1) is compatible with
the intended use .
– Ensure that all limits, conditions and warnings in this manual can be ob-
served .

3.2.1 - Product durability

The lifetime is the average economic duration of the product . The value of life-
time is strongly influenced by the intensity of the manoeuvres, i .e . the sum of all
factors that contribute to product wear (see Table 2) .
To estimate the lifetime of your automation, proceed as follows:
01. Add the values of the items in Table 2 regarding the system conditions;
02. In Graph 1 from the value obtained above, trace vertical line until it inter-
sects the curve; from this point trace a horizontal line until it intersects the
line of the "manoeuvre cycles" . The obtained value is the estimated lifetime
of your product .
The lifetime values specified in the graph are only obtainable if the maintenance
schedule is strictly observed (see chapter "Maintenance schedule") . The esti-
mation of lifetime is made on the basis of design calculations and the results of
tests performed on prototypes . As it is only an estimation, it does not represent
any form of guarantee on the effective lifetime of the product .
Example of calculating the durability of the road barrier (refer to Table 2 and
Graph 1): M5BAR with mobile support (severity index of 10%) - Speed level 3 (se-
verity index of 10%) - Braking (severity index of 10%):
Total severity index = 30%
The estimated durability is approx. 550,000 manoeuvre cycles .
