Description And Intended Use - Nice Moonbus MOFB Instructions Et Recommandations Pour L'installateur

1) Warnings
!
This manual has been especially written for use by qualified fitters.
No information given in this manual can be considered as being of
interest to end users!
This manual refers to MOFB-MOFOB only and cannot be used for dif-
ferent products.
Read the instructions carefully before installing this product. Improper use of
the said product or errors made during connection may jeopardise the correct
operation of the device and the safety of the persons using it.

2) Description and Intended Use

The MOFB and MOFOB photocells are detectors (type D according to EN
standard EN 12453) which can be used for automations for gates. They reveal
obstacles situated on the optical axis between the transmitter (TX) and receiv-
er (RX).
The photocells are equipped with a "BlueBus" communication system. This
means they can easily be connected up to the control unit of all the devices
using two wires only. All the photocells are quite simply connected in parallel,
and the addressing jumpers selected according to the function required (see
Table 1).
3) Installation
!
Only carry out installation work once the electricity supply to the
system has been switched off. Disconnect any buffer batteries pre-
sent.
Begin the installation process by checking the following points:
1. As it is not possible to adjust the orientation when using fixed MOFB pho-
tocells, fitters must check that the surface the device will be fastened to will
enable correct TX-RX centring. Fasten the photocells as shown in Figures
1a and 1b.
2. Position the photocells on the basis of their detection functions according
to the type of automation used. Check the position in Figures 2, 3 and 4,
and fit the jumpers as per Table 1. If the photocell needs to be used as an
4) Addressing and recognition of devices
When addressing using the special jumpers, the special "BlueBus" communi-
cation system enables the control unit to recognise the photocells and assign
them with the correct detection function. Addressing must be carried out on
both the TX and RX (and the jumpers set in the same way). Ensure there are
no other pairs of photocells with the same address.
1. Address the photocells on the basis of the function required, setting the
jumpers as shown in Table 1. Any unused jumpers must be stored in their
proper compartment ready for future use, as shown in Figure 6.
Note: Refer to the instruction manual for control units and command inter-
faces with "BlueBus" technology for a detailed description of the various oper-
ations carried out for each kind of addressing.
Note: to rectify interference problems between the various "BlueBUS" devices,
position the transmitters and receivers as shown in figures 2a and 2b.
2. Programme the devices using the control unit as described in the paragraph
entitled "Recognition of connected devices" in the instruction manual of the
various "BlueBus" interfaces or control units.
Note: If the photocell is used to replace an already existing one, the jumpers
must be set exactly as they were in the old photocell. It is not necessary to
carry out the recognition phase.
3. Adjusting the orientation: it is possible to adjust the orientation of the
adjustable MOFOB photocell. This enables the user to achieve a perfect
alignment, even if the fastening is not excellent. Proceed as per Figure 8 in
order to regulate the orientation. Loosen the screw slightly and move the
mobile part slowly. Then tighten the screw. Follow the signals of the "L"
indicator: the slower the flashes, the better the centring.
The best centring has been achieved for both the MOFB and MOFOB ver-
sions when the indicator flashes very slowly, although performance is also
acceptable when flashes are simply slow. However, the centring is at risk
when the indicator flashes quickly.

• The photocell must operate exclusively via direct TX-RX interpolation. It
must not be used for reflection purposes.
• The photocell must be fastened securely to a rigid surface, which does not
vibrate.
• Use the wires specified in the manuals for control units for the electrical
connections.
• The MOFB-MOFOB photocells can only be connected up to control units
which use "BlueBus" technology.
The non-adjustable version of the MOFB can be used as long as the surface
the device will be fastened to is flat and allows correct TX-RX centring. The
manufacturers recommend using the adjutsable MOFOB version whenever
this centring is not directly possible.
The MOFB and MOFOB photocells can be used along with the new "FT210B"
series of devices (see figures 2a and 2b). The FT210B device uses the "Blue-
BUS" technology and resolves problems related to the electrical connection
of sensitive edges on the mobile leaf (for further details consult the FT210B
use manual).
opening device (see figures 2a, 2b, 3, 4 and the FA1 and FA2 addresses in
table 1), cut the jumper between points "A" both on the TX and on the RX
as shown in fig. 5.
3. Connect the electric cable to the appropriate TX and RX terminals. From an
electrical viewpoint, TX and RX must be both connected in parallel as
shown in Figure 5, and to the "BlueBus" terminal of the interfaces or con-
trol units. It is not necessary to observe any polarity.
