MAINTENANCE SCHEDULE (to be handed to the end user)
m
This maintenance register must be passed on to the new owner of the automation, after having filled in the
relevant sections.
This register must contain a list of all the maintenance activities, repair work and alterations to the automation. The register must be
updated every time work is carried out and must be stored carefully so that it is available for any inspections that may be required
by the relative authorities.
This “Maintenance register” refers to the following automation:
model: M-BAR and L9BAR - serial no. ................. - installed on ................. - at .................................................................
The following attached documents are part of the Maintenance Register:
1) - Maintenance schedule
2) - ............................................................................................
3) - ............................................................................................
4) - ............................................................................................
5) - ............................................................................................
6) - ............................................................................................
According to the enclosed document “Maintenance Schedule”, maintenance operations must be performed at the following
intervals: every 6 months or every 50.000 manoeuvre cycles , depending on the event that occurs first.
MAINTENANCE SCHEDULE
m
Warning! – All maintenance work on this system must
be carried out by qualified technical personnel, in
full compliance with the safety standards provided
for by the laws in force and the safety instructions
specified in the “GENERAL SAFETY WARNINGS
AND PRECAUTIONS ” chapter, at the beginning of
this manual.
In general, this boom gate mechanism does not require special
maintenance; however, regular checks over time will ensure
system efficiency and correct operation of the safety systems
installed.
For maintenance of devices added to the boom gate mechanism,
follow the provisions laid down in the respective maintenance
schedules.
As a general rule, it is advisable to perform a periodic check
every 6 months or 50.000 manoeuvres.
Bear in mind that should the spring break, the boom gate will
nonetheless conform to the requirement set out in section 4.3.4
of the EN 12604:2000 standard.
m
The boom balancing system must be checked at
least 2 times a year, preferably when the seasons
change.
These checks and replacements must be performed at the
scheduled maintenance intervals:
1. disconnect all power supplies
2. check for any deterioration of the components which
form the barrier mechanism, paying particular attention to
corrosion or oxidation of the structural parts; replace any
parts that are below the required standard
3. make sure that all screwed connections are properly
tightened (especially those of the balancing spring)
4. check that there is no clearance between the balancing
lever and the exit shaft. If necessary, fully tighten the
central screw
5. lubricate the swivel head of the balancing spring and the
lower anchor
6. on versions M7BAR and L9BAR , check the perfect
locking between the two boom segments. If necessary,
adjust the expansion screws.
7. place the boom in the vertical position and verify that the
pitch between the coils of the balancing spring is constant
without any deformation
8. unlock and check the correct balancing of the boom and
for any obstacles during manual opening and closing
9. relock the boom and run the testing procedure.
10. Verification of the safeguard against the risk of lifting:
on automations with vertical movement, it is necessary
to check that there is no lifting danger. This test can be
carried out as follows: hang a 20 kg load (e.g. a sand bag)
halfway along the length of the boom then command an
opening manoeuvre and check that during the manoeuvre
the boom does not exceed a height of 50 cm above its
closed position. If the boom exceeds this height, the
motor force must be reduced (refer to the “ Programming
the control unit ” paragraph).
11. If potentially dangerous situations due to the boom’s
movement have been prevented by limiting the impact
force, the latter must be measured according to the EN
12445 standard and, if the “motor force” control is used to
aid the system in reducing the impact force, it is necessary
to test various adjustments to find the one that gives the
best results.
12. Checking the efficiency of the unlocking system:
place the boom in the “closed” position and manually
unlock the gearmotor (refer to the “ Manually unlocking
and locking the gearmotor ” paragraph), making sure
that this occurs without difficulty. Check that the manual
force for moving the boom to the “open” position does
not exceed 200 N (approximately 20 kg); the force is
measured perpendicular to the boom and at 1 m from the
axis of rotation. Lastly, check that the manual release key
is available near the automation.
13. Check the power supply disconnection system:
operate the power disconnection device and disconnect
any available back-up batteries; check that all the LEDs
on the control unit are OFF and that the boom remains
stationary when a command is sent. Check the efficiency
of the locking system to prevent any unintentional or
unauthorised connection.
