MAINTENANCE SCHEDULE
Caution! – 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 safe-
ty instructions specified in Section 1 - - “General safety precau-
tions and warnings”, found at the beginning of this manual.
In general, this road barrier mechanism does not require special main-
tenance; however, regular checks over time will ensure system effi-
ciency and correct operation of the safety systems installed.
For maintenance of devices added to road barrier 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.
It should be noted that even in the event of a spring breaking, the road
barrier mechanism remains compliant with the requirement in 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 bar-
rier mechanism, paying particular attention to corrosion or oxida-
tion of the structural parts. Replace any parts which are below the
required standard.
3
Make sure the screwed connections are properly tightened (espe-
cially those of the balancing spring)
4
Check that there is no play between the balance lever and the out-
put shaft. If necessary, fully tighten the central screw.
5
Lubricate the swivel head of the balancing spring and the lower an-
chor.
6
On the WIDEL version, check the perfect locking between the two
segments of the boom. If necessary, adjust the expansion screws.
7
Place the boom in an upright position and verify that the pitch be-
tween the coils of the balancing spring is constant with no defor-
mation.
8
Release and check the correct balancing of the boom and for any
obstacles during manual opening and closing.
9
Relock and carry out the testing procedure.
10 Check on the safeguard against any lifting hazard:
in auto-
mations with vertical movement you must ensure that there is no
lifting hazard. This test can be done as follows: hang a weight of
20 kg (for example, a sack of gravel) halfway along the length of
the boom; command an Opening manoeuvre and check that dur-
ing the manoeuvre the boom does not exceed a height of 50 cm
above its closed position. If the boom exceeds this height it is nec-
essary to reduce the working force by using the FL trimmer (Sec-
tion 7.1)
11
If the dangerous situations caused by the movement of the boom
have been safeguarded by limiting the force of impact, the impact
force must be measured according to EN Standard 12445 and, if
the control of the “motor force” is used to assist the system for the
reduction of the impact force, it is necessary to experiment and, in
the end, find the adjustment that provides the best results.
12 Check the efficiency of the manual release system:
a - place
the boom in its Closed position and perform the manual release of
the gearmotor (see paragraph 3.6), making sure that it takes place
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 Finally, check that the manual release key
is available near the automatism.
13 Check on the power supply disconnection system:
oper-
ate the power disconnection device and disconnect any avail-
able back-up batteries; check that all the LEDs on the control unit
are OFF and that the boom remains still when a command is sent
Check the efficiency of the locking system to prevent any uninten-
tional or unauthorised connection.
Maintenance schedule
(to be given to the end user of WIDE)
MAINTENANCE REGISTER
Important
– Before passing this maintenance register on to the owner of the automatism, make sure all the gaps are filled in with the informa-
tion required.
This register must contain a list of all the maintenance activities, repair work and alterations to the automatism. The register must be updated ev-
ery 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: WIDE - Serial No.: ...................................... installation date ............................., - at ............................................................................
