Table 4 shows the programming operations of the dip-switch
inside the transmitter and of the BUS Photocells receiver.
8.3 MEMORY STORAGE OF BUS ACCESSORIES
You can add the BUS photocells to the system at any time,
simply by memory-storing them on the board, observing the
following procedure:
Install and program the accessories using the required
address (see paragraph
8.2
)
Cut power to the board.
Connect the two accessories cables to the red
terminal-board J10 (any polarity will do).
Power up the board, taking care to first connect the
main power supply (transformer output) and then any
batteries.
Quickly press once only the SW1 (SET-UP) push-button, to
execute learning. The BUS LED flashes.
Give an OPEN impulse, leaves will move and the BUS
learning procedure is over.
The board has memory stored the BUS accessories. Follow the
instructions in the table below to check if the BUS connection
is correct.
Tab. 5 - Description of BUS LED
Steady light
Normal operation (LED ON even in the
absence of photocells)
Slow flashing
lamp
(flash
every 0.5 sec)
At least one input engaged: photocell
engaged or not aligned, Open A or Open
B or Stop input engaged
Light OFF
(flash every 2.5
sec)
BUS line short circuited
Fast flashing
lamp
(flash
every 0.2 sec)
If you have detected a BUS connection
error, repeat the acquisition procedure. If
the error is repeated, make sure that there
is not more than one accessory with the
same address in the system (also see the
accessories instructions)

9 MEMORY STORING THE RADIO CODE
The control board has an integrated 2-channel decoding
system (DS, SLH, LC) named OMNIDEC. This system makes it
possible to memory-store both total opening (OPEN A) and
partial opening (OPEN B) of the automated system - this is
made possible by an additional receiver module (Fig.10 ref.
) and radio controls on the same frequency.
The 3 types of radio codes (DS, LSH, LC) cannot
coexist.
Only one radio code can be used at a time.
To change over from one code to another, you
must delete the existing one (see paragraph
on deletion), and repeat the memory-storage
procedure.
