5.2) Commissioning
!
Warning: commissioning can take place only after all the test-
ing phases of the automation system have been terminated suc-
cessfully. It is not permissible to execute partial commissioning or to
enable use of the system in makeshift conditions.
1. Before commissioning the automation system inform the owner of
any residual hazards and risks.
6) Maintenance
!
Warning: maintenance operations must be performed in strict
compliance with the safety directions provided in this manual and in
compliance with applicable legislation and standards.
1. Periodically check unit IB and relative photocells (at least every 6
months). This procedure must be performed by executing all the
tests and checks specified in heading 5.1 "Testing".
2. Check that unit IB does not display any signs of deterioration such
as traces of humidity, oxidation, etc. If signs of deterioration are
observed, unit IB must be replaced.
7) Disposal
!
Warning: certain components of the unit may contain pollu-
tants; do not pollute the environment.
This product is made from various kinds of material, some of which
can be recycled. Make sure you recycle or dispose of the product in
compliance with laws and regulations in force locally.
8) Diagnostics and signals
Unit IB is equipped with a LED "L" (see figure 7), the signals of which depend on the operating status.

2. When creating the technical folder to accompany the automation
system the following documents are mandatory: assembly draw-
ing (e.g. Figure 1), electrical wiring diagram (e.g. Figure 8), risk
analysis and solutions adopted; declaration of conformity of the
manufacturer of all the devices utilised (for unit IB use the "EC
Declaration of Conformity" contained in this manual).
3. Include the maintenance prescriptions for unit IB with the system
maintenance plan (see chapter 6).
3. Unit IB is designed to function in normal conditions for at least 10
years, therefore the frequency maintenance
should be increased once this period has elapsed.
Action
Device healthy
Check power supply on red and black wires; if voltage is
correct then unit IB is probably faulty.
During the programming phase it is normal for the LED
to remain lit for approximately 4 seconds. In other circumstances
this signal probably indicates the presence of a fault.
As soon as power is connected it is normal for the LED
to flash at high frequency for approximately 2 seconds.
In other circumstances this signal indicates a bluebus
overload; check connected devices for short circuits or faults.
Check that the photocells are positioned as shown in the
figures relative to the programming type.
Ensure that no other optical devices are interfering with the
photocells.
Program unit IB (see chapter 4)
If devices have been added to or removed from the system
the unit must be reprogrammed (see chapter 0)
