Bar balancing
Check the bar is balanced correctly repeating the operations described in “Bar fixing, spring fitting and bar balancing”. This operation is funda-
mental for the correct functioning and duration of the barrier. If necessary, increase the preloading of the springs in order to compensate for its
wear. See the subsequent paragraph “Extraordinary maintenance and repairs” in the event the springs need to be changed.
FREQUENCY: every 100.000 manoeuvres or 6 months,
failing which the guarantee lapses
.
Control of the force limitation efficiency
Check the correspondence between the true operation and the operation established during installation.
FREQUENCY: every 100.000 manoeuvres or 6 months,
failing which the guarantee lapses
.
Control of the 12V dc battery
Check the charge level of the battery by means of a tester. If replacement is necessary, substitute the flat battery with an original and do not
dispose of it in the environment.
FREQUENCY: every 100.000 manoeuvres or 6 months,
failing which the guarantee lapses
.
Control of the remaining protection and safety devices
Photocells: they can trigger both in opening as well as in closing; check the dip-switch programming. Clean the outer casing.
Check that the following specifications are respected:
• The flashing light is working and visible;
• The adhesive danger sign on the door is well attached and visible;
• The adhesive danger sign on the back of the barrier is well attached and visible. If these signs do not correspond to the stated conditions,
restore their original effectiveness or, if this is impossible, replace them.
FREQUENCY: every 6 months,
failing which the guarantee lapses
.
6. EXTRAORDINARY MAINTENANCE AND REPAIRS
ATTENTION: ON COMPLETION OF THE FIRST 2000 MANOEUVRES, THE ROD BALANCING PROCEDURE MUST BE CARRIED OUT AGAIN.
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).
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.
7. TROUBLESHOOTING
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_ inefficient 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 difficulty 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”).
8. DECOMMISSION
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 flashing light dome
• ABS 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 springs adjusting tie-rods 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.
9.TRANSPORT
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 move-
