EXTRAORDINARY MAINTENANCE AND REPAIRS
If a complicated repair or replacement of electromechanical parts
is necessary, the unit in question (control unit, gearmotor unit)
should be removed in order for the repair to be carried out by the
manufacturer or by authorised technicians. Otherwise, the safety
and reliability of the barrier may be reduced (such as the guarantee
for example).
NOTE: if the barrier is used in a saline environment or
an environment that is highly contaminated by corrosive
chemical reactants, the frequency of the maintenance controls
must be increased due to the increased environmental
deterioration; In this case the external metal cabinet should
also be inspected.
This paragraph deals with the most probable causes of common
faults, in order to promptly re-establish the barrier.
In any case the indicated case study is incomplete (both from a
cause point of view as well as a fault point of view).
a_ The barrier is blocked (open, closed or half-open):
1_ no power supply;
2_ ineffi cient commands;
3_ blown power supply fuse;
4_ photocells (also enabled during opening) active because they
are incorrectly aligned and/or covered (grass, etc);
b_ the barrier continues to open and close;
1_ check the false contacts of the remote control buttons and the
key selector switches that remain on;
c_ the barrier remains open;
1_ the photocells are active because they are not aligned and/or
dirty (mud, etc) and/or covered (grass, etc);
d_ the barrier has diffi culty in opening;
1_ the bar balancing spring needs adjusting;
e_ the barrier lifts/lowers more than the foreseen limits;
1_ the mechanical limit switches need adjusting (see chapter
"LIMIT SWITCH ADJUSTMENT").
When the barrier has reached the end of its useful life it should
be removed and the reusable materials should be recycled. Pay
attention to that which is stipulated by local and/or national laws
and regulations. Care should be taken when recycling the following
parts:
•
cabinet painted with epoxy paint
•
methacrylate fl ashing light dome
•
polycarbonate control unit box
•
electronic cards
•
12V dc dry battery (lead acid)
•
lithium grease inside the reduction gear
•
minor plastic and/or rubber connections and protections.
RESPECT THE ENVIRONMENT!
DISMANTLING WARNINGS: the barrier dismantling operations
must respect the safety measures: therefore, disconnect the power
supply before proceeding. Slacken (not completely) the adjustment
nut of the balancing spring so that the bar can be comfortably and
safely removed. Then unscrew the blocking screws on the base of
the cabinet in order to process as desired.
The bar, which can be purchased on request, is packed separately
from the barrier that is packaged in a cardboard box.
Care and attention must be taken throughout the handling phase.
Ideally, a manual or motorised trolley should be used for lifting
and movement. The items must be stored upright, even for short
periods, respecting the direction that is indicate on the packaging

and taking into consideration that high centres of gravity cause
instability.
The bar must be stored making sure that there are no protruding
parts or loads that could damage it. Once unpacked, make sure
that it is intact. Do not discard the packaging, but rather recycle it
following local laws.
WARNING: to prevent suffocation or similar dangers, do not
allow children to handle the packaging.
