19.6 MAINTENANCE SCHEDULE
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 STEP 1 - "General safety warnings and
precautions", located at the beginning of this manual.
Note – If the system features other devices which are not mentioned in
this manual, please consult the respective maintenance schedules for the
relevant instructions.
Assuming the automation is subjected to normal domestic use, the
periodic inspection of the system should be carried out every 6 months
or, if the automation is used frequently and the door moves rapidly, when
a certain number of manoeuvre cycles have been reached.
To calculate this number of manoeuvres, refer to the estimated durability
parameter (see "Product technical specifications") and schedule a
maintenance intervention every time 10% of total number of the
manoeuvre cycles set for this parameter is reached; for example,
if the total durability is 100,000 manoeuvre cycles, maintenance must be
carried out every 10,000 cycles.
The following checks and replacements must be performed at the
intervals scheduled for maintenance:
A. Disconnect any source of electrical power supply.
B. Check all the equipment comprising the automation for wear
and tear; moreover, check the moving parts to assess their degree
of wear and look for any signs of erosion or oxidation on structural
parts; if necessary, replace any parts that do not offer sufficient
guarantees.
C. Make sure that the product is securely anchored to the fastening
surface and that the fastening nuts are firmly tightened.
D. Check that the manual manoeuvre release mechanism is in good
working order; the force required to operate the release mechanism
must not exceed 220 N.
E. Reconnect the electric power sources and carry out the following
checks in the order in which they are given:
1 Using the transmitter, perform a few trial door opening and closing
manoeuvres, verifying that the leaf moves as it should.
It is worthwhile running a series of tests in order to evaluate whether the
door moves smoothly and to check for any assembly defects and poor
adjustment, as well as the presence of any friction points.
2 Check, one-by-one, that all the safety devices mounted in the system
(photocells, sensitive edges, etc.) work properly. Photocells: make the
device intervene during an Opening or Closing manoeuvre and check
that the control unit stops the manoeuvre and reverses the movement
completely (the warning light flashes twice, stops, and then repeats
the two flashes). Sensitive edges: make the device intervene during
an Opening or Closing manoeuvre and check that the control unit
stops the manoeuvre and reverses the movement for a short while
(the warning light flashes four times, stops, and then repeats the four
flashes).
3 Check that there is no interference between the photocells and other
equipment by proceeding as follows: block the line of sight between
the pair of photocells (Fig. "48") by passing a cylinder (5 cm diameter
and 30 cm length) close to the TX photocell first and then close to
the RX photocell, and, lastly, at the mid-point between the two. Ensure
that in all cases the device engages, changing from the enabled status
to the alarm status and vice versa; lastly, ensure that it triggers the
expected action in the control unit (for example, reversal of movement
during the closing manoeuvre).
4After positioning an obstacle along the door's closing trajectory,
command a closing manoeuvre and check that the automation
reverses the movement as soon as the door touches the obstacle
(safety manoeuvre).
Warning! – use a 5 cm-high piece of wood as the obstacle,
positioning it as shown in Fig. "49".
19.7 MAINTENANCE REGISTER
Important – Before passing this maintenance register on to the owner
of the automation, make sure that all the necessary information has been
filled in.
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 .............................,
serial no. ................................,
installation date .............................,
installation location ..................................................................................
................................................................................................................
................................................................................................................
................................................................................................................

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 ............. months, or every ............. manoeuvre cycles,
depending on the event that occurs first.
