5) Testing and checking operation
After the recognition phase, check that the LED on the photocell starts flashing (both on TX and RX). Check Table 2 for the state of the photocell based on the
way LED "L" flashes.

Warning: After you have added or removed any photocells, the automation
system must be tested again according to the directions contained in the
installation manual.
To check the photocells and make sure that there is no interference with oth-
er devices, pass a 5 cm diameter, 30 cm long cylinder on the optical axis, first
near TX, then near RX and finally at the mid-point between them (shown in
Figure 9) and make sure that in all these cases the device is triggered, switch-
ing from the active to the alarm status and vice-versa; finally, that it causes the
6) Maintenance
The photocells do not require any special maintenance work. However, it is nec-
essary to check them at least once every six months in order to evaluate their con-
dition (presence of damp, oxides, etc.). The outer covering and lenses must be
cleaned, then testing carried out again, as described in the previous paragraph.
6.1) Disposal
As for the installation, the disposal of the product at the end of its effective life,
must be performed by qualified personnel. This product is made of various
types of material, some of which can be recycled while others must be dis-
posed of. Enquire about the recycling or disposal systems available for this
product category in compliance with regulations locally in force.
Warning: some parts of the product may contain polluting or hazardous sub-
stances that, if incorrectly disposed of, could have a damaging effect on the
environment or on the health of individuals.

To check the photocells as an optical presence sensor (type D),according to
the EN 12445 standard, is performed with the 700x300x200mm test paral-
lelepiped with 3 opaque black sides and 3 polished white sides or mirrored as
shown in figure 10 following that stipulated by chapter 7 of the EN
12445:2000 standard (or enclosure A of prEN 12445:2005).
The photocells have been studied and designed in order that that they will
operate in normal conditions for at least 10 years. It is, therefore, necessary
to increase the frequency of the maintenance work carried out on the said
photocells after this period of time has elapsed.
As indicated by the symbol in figure 11, this product
must not be disposed of in household waste. Per-
form "separated collection" for disposal in compli-
ance with regulations locally in force, or return the
product to the manufacturer when purchasing a
replacement.
Heavy fines may be imposed by local laws for the illegal disposal of this prod-
uct.
Detector for gate and door automation systems (type D according to EN standard 12453), consisting in a "TX"
transmitter and "RX" receiver.
TX-RX direct optical interpolation with modulated infrared ray.
The device can only be connected to "BlueBus" networks, from which it receives its power supply and sends
output signals.
1 "BlueBus" unit.
Opaque objects (larger than 50 mm) located on the optical axis between TX and RX, which move more
slowly than 1.6m/s.
20° +/- 25%
Approximately 20°.
Approximately 30° along the horizontal and vertical axes.
Up to 15m for a maximum TX-RX misalignment of ± 5° (the device can detect and signal an obstacle even in
particularly bad weather conditions).
Up to 30m for a maximum TX-RX misalignment of ± 5°.
Up to 50 m.
Up to 7 detectors with the protection function, and 2 with the opening command function.
The automatic synchronism prevents any interference among the various detectors.

Action
Make sure the voltage for the photocell terminals is approximately 8-12
Vdc. If the voltage is correct, the photocell is probably broken.
Repeat the learning procedure on the control unit. Make sure that all the
photocell pairs have different addresses

It is at the very limit of normal operation. Check the TX-RX alignment
and make sure the glasses are clean.
Make sure that the LED on TX flashes once slowly. Check to see if there
is an obstacle between TX and RX. Check the TX-RX alignment
