MAINTENANCE SCHEDULE

Caution!

- System maintenance must be performed by technical

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, SBAR does not require special maintenance. However, reg-
ular checks over time will guarantee system efficiency and ensure cor-
rect operation of the safety systems installed.
If SBAR 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, more specifically, the
period of maintenance can be calculated on the basis of these factors:
• If SBAR is set for use at high speeds, with high force levels or with
the pole weight increased by the use of accessories, more frequent
checks are required. In general; to establish the number of cycles
between each maintenance operation, estimate the durability as spec-
ified in table 4 and plan intervention at least every 10% of the resulting
manoeuvres; e.g. if total durability is 500,000 (*); maintenance should
be performed every 50,000 cycles.

(*) Special warning regarding spring replacement:

the balancing

system is based on the use of a spring. The lifetime of this spring is on
average greater than 500,000 cycles, but for an adequate safety mar-
gin, the spring should be replaced before this limit.

Note also that in the event of spring breakage, SBAR still remains com-
pliant 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

Ensure that all specifications in this manual have been observed,
with special reference to the chapter “1 Safety Instructions”.

2

Check correct balancing of the pole, see paragraph 3.8.

3

Check correct operation of the manual release, see paragraph 3.6.

4

Using the transmitter or key-operated selector switch, perform
tests of opening, closing and stopping the barrier, and ensure that
pole movement corresponds to specifications. Test several times to
check for pole movement and any defects in assembly or adjust-
ment and any possible points of friction.

5

Check operation of all system safety devices one at a time (photo-
cells, sensitive edges, etc.). Each time a device is activated the
“Bluebus” LED on the control unit must flash rapidly twice to con-
firm acknowledgement of the event.

6

Check correct operation of the photocells as follows: depending on
whether one or two pairs of photocells have been installed, one or
two parallelepipeds in rigid material are required (e.g. wooden panels)
with the measurements 70 x 30 x 20 cm. Each parallelepiped must
have three sides, one for each size, in reflective material (e.g. mirror

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. SBAR. - Serial n° ......................... - Date of installation ...................... - at ......................................................................................

The following enclosed documents are part of the Register:

According to the enclosed document “Maintenance Schedule”, maintenance operations must be performed at the following intervals:

or white gloss paint) and three sides in opaque material (e.g. black
matt paint). To test the photocells positioned at 50 cm from the
ground, the parallelepiped must be placed on the ground or raised at
50 cm in the case of photocells placed at 1 m from the ground.

When testing one pair of photocells, the test specimen must be po -
sitioned exactly at the centre of the pole with the 20 cm sides facing
the photocells and moved along the entire length of the pole (

fig. 46

).

When testing two pairs of photocells, the test must first be per-
formed individually for each pair of photocells, using one test spec-
imen, and then repeated using two test specimens.

Each test specimen must be positioned laterally with respect to the
centre of the pole, at a distance of 15 cm sides and then moved
along the entire length of the pole (

fig. 47

).

During these tests, the test specimen must be read by the photo-
cells in any position.

7

To ensure there is no interference with other devices, pass a cylin-
der (diameter 5 cm, length 30 cm) through the optic axis joining the
pair of photocells (

fig. 48

): pass the cylinder first close to the TX

photocell, then close to the RX and lastly at the centre between the
two. Ensure that in all cases the device engages, changing from
the active status to alarm status and vice versa, and that the envis-
aged action is generated in the control unit (for example movement
inversion in the 

Closing

manoeuvre).

8

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 Open-
ing 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).

9

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.

10

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.

11

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
reconnection.
