MAINTENANCE SCHEDULE
Important! – System maintenance must be performed by tech-
nical and qualified personnel, in strict observance of safety
standards as envisaged by current legislation and the safety
precautions stated in Chapter 1 - “General safety warnings and
precautions”, at the start of this manual.
In general, the road barrier does not require special maintenance;
however, regular checks over time will guarantee system efficiency and
ensure correct operation of the safety systems installed.
If the road barrier is equipped with other devices not mentioned in this
manual, follow the instructions in the relative maintenance schedules.
Considering normal domestic use of the automation, periodic checks
of the system are recommended: every 6 months or 50,000 maneou-
vres
.
Note also that in the event of spring breakage, the road barrier still
remains compliant with the requirement in 4.3.4 of the standard EN
12604: 2000.
• The pole balancing system must be checked at least twice a year,
preferably when the season changes.
At the envisaged interval, the following checks and replacements must
be made for maintenance.
1 Disconnect any electrical power source.
2 Check the state of deterioration of all the materials of the barrier,
paying special attention to cases of corrosion or oxidation of the
structural parts; replace the parts that do not provide sufficient
guarantee.
3 Check that the screw connections are adequately tightened (espe-
cially those of the balancing screw)
4 Check the absence of clearance between the balancing lever and
the output shaft. If this is the case, tighten the central screw down.
5 Lubricate the rod end of the balancing screw and the lower bolt.
6 In the M7BAR and LBAR versions, check the perfect locking
between the two pole segments. Use the expansion screws if nec-
essary.
7 Position the pole in the vertical position and make sure that the
pitch between the loops of the balancing screw is constant without
deformations.
8 Release and check the correct balancing of the pole and any
obstacle during manual opening and closing.
9 Release again and carry out the test procedure.
10 Check protection against the risk of lifting: on automations
with vertical movement, it must be ensured that there is no risk of
lifting. This test can be performed as follows: hang a weight of 20
kg mid-way along the pole (for example, a sack of gravel), activate
an Opening manoeuvre and ensure that during operation the pole
does not exceed the height of 50 cm from the closing position. If
the pole exceeds this height, reduce the motor force (see chapter 6
- Table 7).
MAINTENANCE REGISTER
Important – This register must be given to the automation owner after compilation of all required parts.
This register must list all maintenance operations, repairs and modifications performed. The Register must be updated on each operation and
stored in a safe place for future inspections by authorised organisations.
This Maintenance Register refers to the following automation:
mod. MBAR and LBAR - serial n° ......................... - date of installation ......................... - at ...............................................................................
The following enclosed documents are part of the 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 50,000 manoeuvre cycles , depending on which event occurs first.
11 If hazardous situations generated by the moving poles are protect-
ed by means of impact force limitation, measure the force as spec-
ified in the standard EN 12445. If motor force control is used as
auxiliary function with the system for reduction of impact force, test
and identify the setting that obtains the best results.
12 Check efficiency of the release system: place the pole in the
Closing position and manually release the gearmotor (see para-
graph 3.6) ensuring that there is no difficulty with this procedure.
Ensure that the manual force required to move the pole on opening
is no greater than 200 N (approx. 20 Kg); the force is measured
perpendicular to the pole and at 1 m from the rotation axis. Lastly,
ensure that the key required for manual release is available in the
vicinity of the automation.
13 Power supply disconnection system check: by using the pow-
er disconnect device, and disconnecting any buffer batteries, en -
sure that all leds on the control unit are off and that the rod re mains
stationary when any commands are sent. Check efficiency of the
locking device to prevent inadvertent and/or unauthorised connec-
tion.
