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 NUUR - serial no° ................. - installed on .................
- at .................................................................
The following attached documents are part of the Maintenance
Register:
1) - Maintenance schedule

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.

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 NUUR6, 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.
