8 INSTALLATION OF BUS ACCESSORIES
This board is supplied with a BUS circuit enabling easy
connection of a high number of BUS accessories (e.g. up to
16 photocells pairs), using only two cables.
Below we describe the addressing and memory storage of the
encoders and BUS photocells.
For other future accessories, refer to the specific instructions.
Connection of the BUS input to the control board is via the
bipolar cables which come out of the encoders.
Unlike the case of the photocell devices, the polarity of the BUS
line connection determines whether the encoder belongs to
one leaf rather then the other.
This is why you must pay great attention to the indications of
the status LEDs on the body of each encoder (Fig.8).
Below we list the functions of LEDs LD1, DL2, and DL3, and their
statuses:

must always be lighted to guarantee correct connection
between encoder and board.
DL 2
determines the leaf on which the encoder is installed.
Providing the configuration is correct, the automated system
will show: an encoder with DL 2 lighted in the leaf 1, and an
encoder with DL 2 OFF in the leaf 2. If there is an incorrect
connection, i.e. indicating two encoders with the same
status of the DL 2 LEDs, during the learning procedure of the
BUS accessories, the DL 1 LEDs of both encoders show the
FLASHING status. In this situation, refer to the configuration
in TAB.3 to define which encoder connection to rotate.
DL 3
indicates, on a steady flashing beam, the reading
of the pulses while the leaf is moving. When the leaf is
motionless, DL 3 can be either lighted or OFF.
N.B. in particular motionless leaf positions, DL3 may flutter
considerably. This signal must not be considered a fault.

If the A Logic was selected, the board begins to count
the pause time (max 10 min) and, after the required time
has elapsed, give an OPENING pulse to continue the
procedure. Otherwise, if you have selected the EP logic,
give an OPEN pulse to continue the procedure.
Leaf 2 (if present) starts the closing movement an the board
begins to count the delay of the leaf 1 at closing.
After the required time has elapsed, give an OPEN pulse
to make leaf 1 start the closing movement. If leaf 2 is not
present, the pulse given in point 9 directly makes leaf 1
close.
Leaves 1 and 2 (if present) stop when they reach the closing
mechanical stop.
Wait for LEDs LD4 and LD5 to go OFF, which means that the
SETUP procedure has finished.
When the SET-UP procedure has been started,
if the leaves at point 4 and 5 open instead of
closing, the motor power supply cables must
be changed over.
When using the MANUAL SET-UP, the slow-down
spaces, and leaf delays at opening are preset
by the board and cannot be modified. However,
delay at leaf closing and pause time can be
programmed during learning.

8.2 ADDRESSING THE BUS PHOTOCELLS
Important: the same address must be given to
both transmitter and receiver.
Make sure that there are no two or more
photocells pairs with the same address.
If no BUS accessory is used, leave the BUS
connector free (J10 - Fig. 7).
